explains how to contribute changes to the Gitea project. It assumes you have followed the [installation instructions](https://github.com/go-gitea/docs/tree/master/en-US/installation). Sensitive security-related issues should be reported to [security@gitea.io](mailto:security@gitea.io). - -## Bug reports - -Please search the issues on the issue tracker with a variety of keywords to ensure your bug is not already reported. - -If unique, [open an issue](https://github.com/go-gitea/gitea/issues/new) and answer the questions so we can understand and reproduce the problematic behavior. - -To show us that the issue you are having is in Gitea itself, please write clear, concise instructions so we can reproduce the behavior (even if it seems obvious). The more detailed and specific you are, the faster we can fix the issue. Check out [How to Report Bugs Effectively](http://www.chiark.greenend.org.uk/~sgtatham/bugs.html). - -Please be kind, remember that Gitea comes at no cost to you, and you're getting free help. - -## Discuss your design - -The project welcomes submissions but please let everyone know what you're working on if you want to change or add something to the Gitea repositories. - -Before starting to write something new for the Gitea project, please [file an issue](https://github.com/go-gitea/gitea/issues/new). Significant changes must go through the [change proposal process](https://github.com/go-gitea/proposals) before they can be accepted. - -This process gives everyone a chance to validate the design, helps prevent duplication of effort, and ensures that the idea fits inside the goals for the project and tools. It also checks that the design is sound before code is written; the code review tool is not the place for high-level discussions. - -## Testing redux - -Before sending code out for review, run all the tests for the whole tree to make sure the changes don't break other usage and keep the compatibility on upgrade. To make sure you are running the test suite exactly like we do, you should install the CLI for [Drone CI](https://github.com/drone/drone), as we are using the server for continous testing, following [these instructions](http://readme.drone.io/0.5/install/cli/). After that you can simply call `drone exec` within your working directory and it will try to run the test suite locally. - -## Code review - -Changes to Gitea must be reviewed before they are accepted, no matter who makes the change even if it is an owner or a maintainer. We use GitHub's pull request workflow to do that and we also use [LGTM](http://lgtm.co) to ensure every PR is reviewed by at least 2 maintainers. - -Please try to make your pull request easy to review for us. Please read the "[How to get faster PR reviews](https://github.com/kubernetes/community/blob/master/contributors/devel/faster_reviews.md)" guide, it has lots of useful tips for any project you may want to contribute. Some of the key points: - -* Make small pull requests. The smaller, the faster to review and the more likely it will be merged soon. -* Don't make changes unrelated to your PR. Maybe there are typos on some comments, maybe refactoring would be welcome on a function... but if that is not related to your PR, please make *another* PR for that. -* Split big pull requests into multiple small ones. An incremental change will be faster to review than a huge PR. - -## Sign your work - -The sign-off is a simple line at the end of the explanation for the patch. Your signature certifies that you wrote the patch or otherwise have the right to pass it on as an open-source patch. The rules are pretty simple: If you can certify [DCO](DCO), then you just add a line to every git commit message: - -``` -Signed-off-by: Joe Smith -``` - -Please use your real name, we really dislike pseudonyms or anonymous contributions. We are in the open-source world without secrets. If you set your `user.name` and `user.email` git configs, you can sign your commit automatically with `git commit -s`. - -## Maintainers - -To make sure every PR is checked, we have [team maintainers](https://github.com/orgs/go-gitea/teams/maintainers). Every PR **MUST** be reviewed by at least two maintainers (or owners) before it can get merged. A maintainer should be a contributor of Gitea (or Gogs) and contributed at least 4 accepted PRs. A contributor should apply as a maintainer in the [Discord #develop channel](https://discord.gg/NsatcWJ). The owners or the team maintainers may invite the contributor. A maintainer should spend some time on code reviews. If a maintainer has no time to do that, they should apply to leave the maintainers team and we will give them the honor of being a member of the [advisors team](https://github.com/orgs/go-gitea/teams/advisors). Of course, if an advisor has time to code review, we will gladly welcome them back to the maintainers team. If a maintainer is inactive for more than 3 months and forgets to leave the maintainers team, the owners may move him or her from the maintainers team to the advisors team. - -## Owners - -Since Gitea is a pure community organization without any company support, to keep the development healthy we will elect three owners every year. All contributors may vote to elect up to three candidates, one of which will be the main owner, and the other two the assistant owners. When the new owners have been elected, the old owners will give up ownership to the newly elected owners. If an owner is unable to do so, the other owners will assist in ceding ownership to the newly elected owners. - -After the election, the new owners should proactively agree with our [CONTRIBUTING](CONTRIBUTING.md) requirements on the [Discord #general channel](https://discord.gg/NsatcWJ). Below are the words to speak: - -``` -I'm honored to having been elected an owner of Gitea, I agree with [CONTRIBUTING](CONTRIBUTING.md). I will spend part of my time on Gitea and lead the development of Gitea. -``` - -To honor the past owners, here's the history of the owners and the time they served: - -* 2016-11-04 ~ 2017-12-31 - * [Lunny Xiao](https://github.com/lunny) - * [Thomas Boerger](https://github.com/tboerger) - * [Kim Carlbäcker](https://github.com/bkcsoft) - -## Versions - -Gitea has the `master` branch as a tip branch and has version branches such as `v0.9`. `v0.9` is a release branch and we will tag `v0.9.0` for binary download. If `v0.9.0` has bugs, we will accept pull requests on the `v0.9` branch and publish a `v0.9.1` tag, after bringing the bug fix also to the master branch. - -Since the `master` branch is a tip version, if you wish to use Gitea in production, please download the latest release tag version. All the branches will be protected via GitHub, all the PRs to every branch must be reviewed by two maintainers and must pass the automatic tests. - -## Copyright - -Code that you contribute should use the standard copyright header: - -``` -// Copyright 2017 The Gitea Authors.

See the [wiki][] for various options to do this. - -Syntax-wise, it is as close as possible to jQuery, with the same function names when possible, and that warm and fuzzy chainable interface. jQuery being the ultra-popular library that it is, I felt that writing a similar HTML-manipulating library was better to follow its API than to start anew (in the same spirit as Go's `fmt` package), even though some of its methods are less than intuitive (looking at you, [index()][index]...). - -## Installation - -Please note that because of the net/html dependency, goquery requires Go1.1+. - - $ go get github.com/PuerkitoBio/goquery - -(optional) To run unit tests: - - $ cd $GOPATH/src/github.com/PuerkitoBio/goquery - $ go test - -(optional) To run benchmarks (warning: it runs for a few minutes): - - $ cd $GOPATH/src/github.com/PuerkitoBio/goquery - $ go test -bench=".*" - -## Changelog - -**Note that goquery's API is now stable, and will not break.** - -* **2017-02-12 (v1.1.0)** : Add `SetHtml` and `SetText` (thanks to @glebtv). -* **2016-12-29 (v1.0.2)** : Optimize allocations for `Selection.Text` (thanks to @radovskyb). -* **2016-08-28 (v1.0.1)** : Optimize performance for large documents. -* **2016-07-27 (v1.0.0)** : Tag version 1.0.0. -* **2016-06-15** : Invalid selector strings internally compile to a `Matcher` implementation that never matches any node (instead of a panic). So for example, `doc.Find("~")` returns an empty `*Selection` object. -* **2016-02-02** : Add `NodeName` utility function similar to the DOM's `nodeName` property. It returns the tag name of the first element in a selection, and other relevant values of non-element nodes (see godoc for details). Add `OuterHtml` utility function similar to the DOM's `outerHTML` property (named `OuterHtml` in small caps for consistency with the existing `Html` method on the `Selection`). -* **2015-04-20** : Add `AttrOr` helper method to return the attribute's value or a default value if absent. Thanks to [piotrkowalczuk][piotr]. -* **2015-02-04** : Add more manipulation functions - Prepend* - thanks again to [Andrew Stone][thatguystone]. -* **2014-11-28** : Add more manipulation functions - ReplaceWith*, Wrap* and Unwrap - thanks again to [Andrew Stone][thatguystone]. -* **2014-11-07** : Add manipulation functions (thanks to [Andrew Stone][thatguystone]) and `*Matcher` functions, that receive compiled cascadia selectors instead of selector strings, thus avoiding potential panics thrown by goquery via `cascadia.MustCompile` calls. This results in better performance (selectors can be compiled once and reused) and more idiomatic error handling (you can handle cascadia's compilation errors, instead of recovering from panics, which had been bugging me for a long time). Note that the actual type expected is a `Matcher` interface, that `cascadia.Selector` implements. Other matcher implementations could be used. -* **2014-11-06** : Change import paths of net/html to golang.org/x/net/html (see https://groups.google.com/forum/#!topic/golang-nuts/eD8dh3T9yyA). Make sure to update your code to use the new import path too when you call goquery with `html.Node`s. -* **v0.3.2** : Add `NewDocumentFromReader()` (thanks jweir) which allows creating a goquery document from an io.Reader. -* **v0.3.1** : Add `NewDocumentFromResponse()` (thanks assassingj) which allows creating a goquery document from an http response. -* **v0.3.0** : Add `EachWithBreak()` which allows to break out of an `Each()` loop by returning false. This function was added instead of changing the existing `Each()` to avoid breaking compatibility. -* **v0.2.1** : Make go-getable, now that [go.net/html is Go1.0-compatible][gonet] (thanks to @matrixik for pointing this out). -* **v0.2.0** : Add support for negative indices in Slice(). **BREAKING CHANGE** `Document.Root` is removed, `Document` is now a `Selection` itself (a selection of one, the root element, just like `Document.Root` was before). Add jQuery's Closest() method. -* **v0.1.1** : Add benchmarks to use as baseline for refactorings, refactor Next...() and Prev...() methods to use the new html package's linked list features (Next/PrevSibling, FirstChild). Good performance boost (40+% in some cases). -* **v0.1.0** : Initial release. - -## API - -goquery exposes two structs, `Document` and `Selection`, and the `Matcher` interface. Unlike jQuery, which is loaded as part of a DOM document, and thus acts on its containing document, goquery doesn't know which HTML document to act upon. So it needs to be told, and that's what the `Document` type is for. It holds the root document node as the initial Selection value to manipulate. - -jQuery often has many variants for the same function (no argument, a selector string argument, a jQuery object argument, a DOM element argument, ...). Instead of exposing the same features in goquery as a single method with variadic empty interface arguments, statically-typed signatures are used following this naming convention: - -* When the jQuery equivalent can be called with no argument, it has the same name as jQuery for the no argument signature (e.g.: `Prev()`), and the version with a selector string argument is called `XxxFiltered()` (e.g.: `PrevFiltered()`) -* When the jQuery equivalent **requires** one argument, the same name as jQuery is used for the selector string version (e.g.: `Is()`) -* The signatures accepting a jQuery object as argument are defined in goquery as `XxxSelection()` and take a `*Selection` object as argument (e.g.: `FilterSelection()`) -* The signatures accepting a DOM element as argument in jQuery are defined in goquery as `XxxNodes()` and take a variadic argument of type `*html.Node` (e.g.: `FilterNodes()`) -* The signatures accepting a function as argument in jQuery are defined in goquery as `XxxFunction()` and take a function as argument (e.g.: `FilterFunction()`) -* The goquery methods that can be called with a selector string have a corresponding version that take a `Matcher` interface and are defined as `XxxMatcher()` (e.g.: `IsMatcher()`) - -Utility functions that are not in jQuery but are useful in Go are implemented as functions (that take a `*Selection` as parameter), to avoid a potential naming clash on the `*Selection`'s methods (reserved for jQuery-equivalent behaviour). - -The complete [godoc reference documentation can be found here][doc]. - -Please note that Cascadia's selectors do not necessarily match all supported selectors of jQuery (Sizzle). See the [cascadia project][cascadia] for details. Invalid selector strings compile to a `Matcher` that fails to match any node. Behaviour of the various functions that take a selector string as argument follows from that fact, e.g. (where `~` is an invalid selector string): - -* `Find("~")` returns an empty selection because the selector string doesn't match anything. -* `Add("~")` returns a new selection that holds the same nodes as the original selection, because it didn't add any node (selector string didn't match anything). -* `ParentsFiltered("~")` returns an empty selection because the selector string doesn't match anything. -* `ParentsUntil("~")` returns all parents of the selection because the selector string didn't match any element to stop before the top element. - -## Examples - -See some tips and tricks in the [wiki][]. - -Adapted from example_test.go: - -```Go -package main - -import ( - "fmt" - "log" - - "github.com/PuerkitoBio/goquery" -) - -func ExampleScrape() { - doc, err := goquery.NewDocument("http://metalsucks.net") - if err != nil { - log.Fatal(err) - } - - // Find the review items - doc.Find(".sidebar-reviews article .content-block").Each(func(i int, s *goquery.Selection) { - // For each item found, get the band and title - band := s.Find("a").Text() - title := s.Find("i").Text() - fmt.Printf("Review %d: %s - %s\n", i, band, title) - }) -} - -func main() { - ExampleScrape() -} -``` - -## License - -The [BSD 3-Clause license][bsd], the same as the [Go language][golic].

- dec := NewU32Base128Decoder(&buf) - x, err := dec.GetU32() - -## Use Cases - -Using fixed width integers, such as uint32 and uint64, usually waste large amounts of space, especially when encoding small values. -Optimally, smaller numbers should take less space to represent. - -Using integer encoding algorithms is especially common in specific applications, such as storing edge lists or indexes for search engines. -In these situations, you have a sorted list of numbers that you want to keep as compactly as possible in memory. -Additionally, by storing only the difference between the given number and the previous (delta encoding), the numbers are quite small, and thus compress well. - -For an explicit example, the Web Data Commons Hyperlink Graph contains 128 billion edges linking page A to page B, where each page is represented by a 32 bit integer. -By converting all these edges to 64 bit integers (32 | 32), sorting them, and then using delta encoding, memory usage can be reduced from 64 bits per edge down to only 9 bits per edge using the Base128 integer encoding algorithm. -This figure improves even further if compressed using conventional compression algorithms (3 bits per edge). - -## Encodings supported - -`govarint` supports: - -+ Base128 [32, 64] - each byte uses 7 bits for encoding the integer and 1 bit for indicating if the integer requires another byte -+ Group Varint [32] - integers are encoded in blocks of four - one byte encodes the size of the following four integers, then the values of the four integers follows - -Group Varint consistently beats Base128 in decompression speed but Base128 may offer improved compression ratios depending on the distribution of the supplied integers. -

Every language corresponding to a locale file, for example, under `conf/locale` folder of [gogsweb](https://github.com/gogits/gogsweb/tree/master/conf/locale), there are two files called `locale_en-US.ini` and `locale_zh-CN.ini`. - -The name and extensions of locale files can be anything, but we strongly recommend you to follow the style of gogsweb. - -## Minimal example - -Here are two simplest locale file examples: - -File `locale_en-US.ini`: - -```ini -hi = hello, %s -bye = goodbye -``` - -File `locale_zh-CN.ini`: - -```ini -hi = 您好，%s -bye = 再见 -``` - -### Do Translation - -There are two ways to do translation depends on which way is the best fit for your application or framework. - -Directly use package function to translate: - -```go -i18n.Tr("en-US", "hi", "Unknwon") -i18n.Tr("en-US", "bye") -``` - -Or create a struct and embed it: - -```go -type MyController struct{ - // ...other fields - i18n.Locale -} - -//... - -func ... { - c := &MyController{ - Locale: i18n.Locale{"en-US"}, - } - _ = c.Tr("hi", "Unknwon") - _ = c.Tr("bye") -} -``` - -Code above will produce correspondingly: - -- English `en-US`：`hello, Unknwon`, `goodbye` -- Chinese `zh-CN`：`您好，Unknwon`, `再见` - -## Section - -For different pages, one key may map to different values. Therefore, i18n module also uses the section feature of INI format configuration to achieve section. - -For example, the key name is `about`, and we want to show `About` in the home page and `About Us` in about page. Then you can do following: - -Content in locale file: - -```ini -about = About - -[about] -about = About Us -``` - -Get `about` in home page: - -```go -i18n.Tr("en-US", "about") -``` - -Get `about` in about page: - -```go -i18n.Tr("en-US", "about.about") -``` - -### Ambiguity - -Because dot `.` is sign of section in both [INI parser](https://github.com/go-ini/ini) and locale files, so when your key name contains `.` will cause ambiguity. At this point, you just need to add one more `.` in front of the key. - -For example, the key name is `about.`, then we can use: - -```go -i18n.Tr("en-US", ".about.") -``` - -to get expect result. - -## Helper tool - -Module i18n provides a command line helper tool beei18n for simplify steps of your development. You can install it as follows: - - go get github.com/Unknwon/i18n/ui18n - -### Sync locale files - -Command `sync` allows you use a exist local file as the template to create or sync other locale files: - - ui18n sync srouce_file.ini other1.ini other2.ini - -This command can operate 1 or more files in one command. - -## More information - -- The first locale you load to the module is considered as **default locale**. -- When matching non-default locale and didn't find the string, i18n will have a second try on default locale. -- If i18n still cannot find string in the default locale, raw string will be returned. For instance, when the string is `hi` and it does not exist in locale file, simply return `hi` as output. diff --git a/vendor/github.com/Unknwon/paginater/README.md b/vendor/github.com/Unknwon/paginater/README.md deleted file mode 100644 index 8e608ed3ea..0000000000 --- a/vendor/github.com/Unknwon/paginater/README.md +++ /dev/null @@ -1,65 +0,0 @@ -Paginater [![Build Status](https://drone.io/github.com/Unknwon/paginater/status.png)](https://drone.io/github.com/Unknwon/paginater/latest) [![](http://gocover.io/_badge/github.com/Unknwon/paginater)](http://gocover.io/github.com/Unknwon/paginater) -========= - -Package paginater is a helper module for custom pagination calculation. - -## Installation - - go get github.com/Unknwon/paginater - -## Getting Started - -The following code shows an example of how to use paginater: - -```go -package main - -import "github.com/Unknwon/paginater" - -func main() { - // Arguments: - // - Total number of rows - // - Number of rows in one page - // - Current page number - // - Number of page links - p := paginater.New(45, 10, 3, 3) - - // Then use p as a template object named "Page" in "demo.html" - // ... -} -``` - -`demo.html` - -```html -{{if not .Page.IsFirst}}[First](1){{end}} -{{if .Page.HasPrevious}}[Previous]({{.Page.Previous}}){{end}} - -{{range .Page.Pages}} - {{if eq .Num -1}} - ... - {{else}} - {{.Num}}{{if .IsCurrent}}(current){{end}} - {{end}} -{{end}} - -{{if .Page.HasNext}}[Next]({{.Page.Next}}){{end}} -{{if not .Page.IsLast}}[Last]({{.Page.TotalPages}}){{end}} -``` - -Possible output: - -``` -[First](1) [Previous](2) ... 2 3(current) 4 ...

This decision is made based on the fact that Couchbase FTS always uses Batches. - -NOTE: As a side-effect of this decision, it should be clear that performance tuning may depend on the batch size, which may in-turn require changes in FTS. - -From this point forward, only Batch mutations will be discussed. - -Sequence of Operations: - -1. For each document in the batch, search through all existing segments. The goal is to build up a per-segment bitset which tells us which documents in that segment are obsoleted by the addition of the new segment we're currently building. NOTE: we're not ready for this change to take effect yet, so rather than this operation mutating anything, they simply return bitsets, which we can apply later. Logically, this is something like: - - ``` - foreach segment { - dict := segment.Dictionary("\_id") - postings := empty postings list - foreach docID { - postings = postings.Or(dict.PostingsList(docID, nil)) - } - } - ``` - - NOTE: it is illustrated above as nested for loops, but some or all of these could be concurrently. The end result is that for each segment, we have (possibly empty) bitset. - -2. Also concurrent with 1, the documents in the batch are analyzed. This analysis proceeds using the existing analyzer pool. - -3. (after 2 completes) Analyzed documents are fed into a function which builds a new Segment representing this information. - -4.

When a caller gets an IndexReader, they get a copy of this pointer, and can use it as long as they like. The IndexSnapshot contains SegmentSnapshots, which only contain pointers to immutable segments. The deleted posting lists associated with a segment change over time, but the particular deleted posting list in YOUR snapshot is immutable. This gives a stable view of the data. - -#### Term Search - -Term search is the only searching primitive exposed in today's bleve.index API. This ultimately could limit our ability to take advantage of the indexing improvements, but it also means it will be easier to get a first version of this working. - -A term search for term T in field F will look something like this: - -``` - searchResultPostings = empty - foreach segment { - dict := segment.Dictionary(F) - segmentResultPostings = dict.PostingsList(T, segmentSnapshotDeleted) - // make segmentLocal numbers into global numbers, and flip bits in searchResultPostings - } -``` - -The searchResultPostings will be a new implementation of the TermFieldReader inteface. - -As a reminder this interface is: - -``` -// TermFieldReader is the interface exposing the enumeration of documents -// containing a given term in a given field. Documents are returned in byte -// lexicographic order over their identifiers. -type TermFieldReader interface { - // Next returns the next document containing the term in this field, or nil - // when it reaches the end of the enumeration. The preAlloced TermFieldDoc - // is optional, and when non-nil, will be used instead of allocating memory. - Next(preAlloced *TermFieldDoc) (*TermFieldDoc, error) - - // Advance resets the enumeration at specified document or its immediate - // follower. - Advance(ID IndexInternalID, preAlloced *TermFieldDoc) (*TermFieldDoc, error) - - // Count returns the number of documents contains the term in this field. - Count() uint64 - Close() error -} -``` - -At first glance this appears problematic, we have no way to return documents in order of their identifiers. But it turns out the wording of this perhaps too strong, or a bit ambiguous. Originally, this referred to the external identifiers, but with the introduction of a distinction between internal/external identifiers, returning them in order of their internal identifiers is also acceptable. **ASIDE**: the reason for this is that most callers just use Next() and literally don't care what the order is, they could be in any order and it would be fine. There is only one search that cares and that is the ConjunctionSearcher, which relies on Next/Advance having very specific semantics. Later in this document we will have a proposal to split into multiple interfaces: - -- The weakest interface, only supports Next() no ordering at all. -- Ordered, supporting Advance() -- And/Or'able capable of internally efficiently doing these ops with like interfaces (if not capable then can always fall back to external walking) - -But, the good news is that we don't even have to do that for our first implementation. As long as the global numbers we use for internal identifiers are consistent within this IndexSnapshot, then Next() will be ordered by ascending document number, and Advance() will still work correctly. - -NOTE: there is another place where we rely on the ordering of these hits, and that is in the "\_id" sort order. Previously this was the natural order, and a NOOP for the collector, now it must be implemented by actually sorting on the "\_id" field. We probably should introduce at least a marker interface to detect this. - -An ASCII art example: - -``` -Let's start with the IndexSnapshot we ended with earlier: - -3 - Index Batch [ C' ] - - segment 0 1 2 - numbers [ 1 2 3 ] [ 1 ] [ 1 ] - \_id [ A B C ] [ B ] [ C ] - - Compute bitset segment-0-deleted-by-2: - [ 0 0 1 ] - - OR it with previous ([ 0 1 0 ]) (call it 0-12) - [ 0 1 1 ] - -Compute bitset segment-1-deleted-by-2: - [ 0 0 0 ] - -OR it with previous (nil) - still just nil - - - IndexSnapshot - segments [ 0 1 2 ] - deleted [ 0-12 nil nil ] - -Now let's search for the term 'cat' in the field 'desc' and let's assume that Document C (both versions) would match it. - -Concurrently: - - - Segment 0 - - Get Term Dictionary For Field 'desc' - - From it get Postings List for term 'cat' EXCLUDING 0-12 - - raw segment matches [ 0 0 1 ] but excluding [ 0 1 1 ] gives [ 0 0 0 ] - - Segment 1 - - Get Term Dictionary For Field 'desc' - - From it get Postings List for term 'cat' excluding nil - - [ 0 ] - - Segment 2 - - Get Term Dictionary For Field 'desc' - - From it get Postings List for term 'cat' excluding nil - - [ 1 ] - -Map local bitsets into global number space (global meaning cross-segment but still unique to this snapshot) - -IndexSnapshot already should have mapping something like: -0 - Offset 0 -1 - Offset 3 (because segment 0 had 3 docs) -2 - Offset 4 (becuase segment 1 had 1 doc) - -This maps to search result bitset: - -[ 0 0 0 0 1] - -Caller would call Next() and get doc number 5 (assuming 1 based indexing for now) - -Caller could then ask to get term locations, stored fields, external doc ID for document number 5. Internally in the IndexSnapshot, we can now convert that back, and realize doc number 5 comes from segment 2, 5-4=1 so we're looking for doc number 1 in segment 2. That happens to be C... - -``` - -#### Future improvements - -In the future, interfaces to detect these non-serially operating TermFieldReaders could expose their own And() and Or() up to the higher level Conjunction/Disjunction searchers. Doing this alone offers some win, but also means there would be greater burden on the Searcher code rewriting logical expressions for maximum performance. - -Another related topic is that of peak memory usage. With serially operating TermFieldReaders it was necessary to start them all at the same time and operate in unison. However, with these non-serially operating TermFieldReaders we have the option of doing a few at a time, consolidating them, dispoting the intermediaries, and then doing a few more. For very complex queries with many clauses this could reduce peak memory usage. - - -### Memory Tracking - -All segments must be able to produce two statistics, an estimate of their explicit memory usage, and their actual size on disk (if any). For in-memory segments, disk usage could be zero, and the memory usage represents the entire information content. For mmap-based disk segments, the memory could be as low as the size of tracking structure itself (say just a few pointers). - -This would allow the implementation to throttle or block incoming mutations when a threshold memory usage has (or would be) exceeded. - -### Persistence - -Obviously, we want to support (but maybe not require) asynchronous persistence of segments. My expectation is that segments are initially built in memory. At some point they are persisted to disk. This poses some interesting challenges. - -At runtime, the state of an index (it's IndexSnapshot) is not only the contents of the segments, but also the bitmasks of deleted documents. These bitmasks indirectly encode an ordering in which the segments were added. The reason is that the bitmasks encode which items have been obsoleted by other (subsequent or more future) segments. In the runtime implementation we compute bitmask deltas and then merge them at the same time we bring the new segment in. One idea is that we could take a similar approach on disk. When we persist a segment, we persist the bitmask deltas of segments known to exist at that time, and eventually these can get merged up into a base segment deleted bitmask. - -This also relates to the topic rollback, addressed next... - - -### Rollback - -One desirable property in the Couchbase ecosystem is the ability to rollback to some previous (though typically not long ago) state. One idea for keeping this property in this design is to protect some of the most recent segments from merging. Then, if necessary, they could be "undone" to reveal previous states of the system. In these scenarios "undone" has to properly undo the deleted bitmasks on the other segments. Again, the current thinking is that rather than "undo" anything, it could be work that was deferred in the first place, thus making it easier to logically undo. - -Another possibly related approach would be to tie this into our existing snapshot mechanism. Perhaps simulating a slow reader (holding onto index snapshots) for some period of time, can be the mechanism to achieve the desired end goal. - - -### Internal Storage - -The bleve.index API has support for "internal storage". The ability to store information under a separate name space. - -This is not used for high volume storage, so it is tempting to think we could just put a small k/v store alongside the rest of the index. But, the reality is that this storage is used to maintain key information related to the rollback scenario. Because of this, its crucial that ordering and overwriting of key/value pairs correspond with actual segment persistence in the index. Based on this, I believe its important to put the internal key/value pairs inside the segments themselves. But, this also means that they must follow a similar "deleted" bitmask approach to obsolete values in older segments. But, this also seems to substantially increase the complexity of the solution because of the separate name space, it would appear to require its own bitmask. Further keys aren't numeric, which then implies yet another mapping from internal key to number, etc. - -More thought is required here. - -### Merging - -The segmented index approach requires merging to prevent the number of segments from growing too large. - -Recent experience with LSMs has taught us that having the correct merge strategy can make a huge difference in the overall performance of the system.

(July 2013) -A boiling liquid expanding vapor explosion (BLEVE, /ˈblɛviː/ blev-ee) is an explosion caused by the rupture of a vessel containing a pressurized liquid above its boiling point.[1] -Contents [hide] -1 Mechanism -1.1 Water example -1.2 BLEVEs without chemical reactions -2 Fires -3 Incidents -4 Safety measures -5 See also -6 References -7 External links -Mechanism[edit] - -This section needs additional citations for verification. Please help improve this article by adding citations to reliable sources. Unsourced material may be challenged and removed. (July 2013) -There are three characteristics of liquids which are relevant to the discussion of a BLEVE: -If a liquid in a sealed container is boiled, the pressure inside the container increases. As the liquid changes to a gas it expands - this expansion in a vented container would cause the gas and liquid to take up more space. In a sealed container the gas and liquid are not able to take up more space and so the pressure rises. Pressurized vessels containing liquids can reach an equilibrium where the liquid stops boiling and the pressure stops rising. This occurs when no more heat is being added to the system (either because it has reached ambient temperature or has had a heat source removed). -The boiling temperature of a liquid is dependent on pressure - high pressures will yield high boiling temperatures, and low pressures will yield low boiling temperatures. A common simple experiment is to place a cup of water in a vacuum chamber, and then reduce the pressure in the chamber until the water boils. By reducing the pressure the water will boil even at room temperature. This works both ways - if the pressure is increased beyond normal atmospheric pressures, the boiling of hot water could be suppressed far beyond normal temperatures. The cooling system of a modern internal combustion engine is a real-world example. -When a liquid boils it turns into a gas. The resulting gas takes up far more space than the liquid did. -Typically, a BLEVE starts with a container of liquid which is held above its normal, atmospheric-pressure boiling temperature. Many substances normally stored as liquids, such as CO2, oxygen, and other similar industrial gases have boiling temperatures, at atmospheric pressure, far below room temperature. In the case of water, a BLEVE could occur if a pressurized chamber of water is heated far beyond the standard 100 °C (212 °F). That container, because the boiling water pressurizes it, is capable of holding liquid water at very high temperatures. -If the pressurized vessel, containing liquid at high temperature (which may be room temperature, depending on the substance) ruptures, the pressure which prevents the liquid from boiling is lost. If the rupture is catastrophic, where the vessel is immediately incapable of holding any pressure at all, then there suddenly exists a large mass of liquid which is at very high temperature and very low pressure. This causes the entire volume of liquid to instantaneously boil, which in turn causes an extremely rapid expansion. Depending on temperatures, pressures and the substance involved, that expansion may be so rapid that it can be classified as an explosion, fully capable of inflicting severe damage on its surroundings. -Water example[edit] -Imagine, for example, a tank of pressurized liquid water held at 204.4 °C (400 °F). This vessel would normally be pressurized to 1.7 MPa (250 psi) above atmospheric ("gauge") pressure. Were the tank containing the water to split open, there would momentarily exist a volume of liquid water which is -at atmospheric pressure, and -204.4 °C (400 °F). -At atmospheric pressure the boiling point of water is 100 °C (212 °F) - liquid water at atmospheric pressure cannot exist at temperatures higher than 100 °C (212 °F). It is obvious, then, that 204.4 °C (400 °F) liquid water at atmospheric pressure must immediately flash to gas causing an explosion. -BLEVEs without chemical reactions[edit] -It is important to note that a BLEVE need not be a chemical explosion - nor does there need to be a fire - however if a flammable substance is subject to a BLEVE it may also be subject to intense heating, either from an external source of heat which may have caused the vessel to rupture in the first place or from an internal source of localized heating such as skin friction. This heating can cause a flammable substance to ignite, adding a secondary explosion caused by the primary BLEVE. While blast effects of any BLEVE can be devastating, a flammable substance such as propane can add significantly to the danger. -Bleve explosion.svg -While the term BLEVE is most often used to describe the results of a container of flammable liquid rupturing due to fire, a BLEVE can occur even with a non-flammable substance such as water,[2] liquid nitrogen,[3] liquid helium or other refrigerants or cryogens, and therefore is not usually considered a type of chemical explosion. -Fires[edit] -BLEVEs can be caused by an external fire near the storage vessel causing heating of the contents and pressure build-up. While tanks are often designed to withstand great pressure, constant heating can cause the metal to weaken and eventually fail. If the tank is being heated in an area where there is no liquid, it may rupture faster without the liquid to absorb the heat. Gas containers are usually equipped with relief valves that vent off excess pressure, but the tank can still fail if the pressure is not released quickly enough.[1] Relief valves are sized to release pressure fast enough to prevent the pressure from increasing beyond the strength of the vessel, but not so fast as to be the cause of an explosion. An appropriately sized relief valve will allow the liquid inside to boil slowly, maintaining a constant pressure in the vessel until all the liquid has boiled and the vessel empties. -If the substance involved is flammable, it is likely that the resulting cloud of the substance will ignite after the BLEVE has occurred, forming a fireball and possibly a fuel-air explosion, also termed a vapor cloud explosion (VCE). If the materials are toxic, a large area will be contaminated.[4] -Incidents[edit] -The term "BLEVE" was coined by three researchers at Factory Mutual, in the analysis of an accident there in 1957 involving a chemical reactor vessel.[5] -In August 1959 the Kansas City Fire Department suffered its largest ever loss of life in the line of duty, when a 25,000 gallon (95,000 litre) gas tank exploded during a fire on Southwest Boulevard killing five firefighters. This was the first time BLEVE was used to describe a burning fuel tank.[citation needed] -Later incidents included the Cheapside Street Whisky Bond Fire in Glasgow, Scotland in 1960; Feyzin, France in 1966; Crescent City, Illinois in 1970; Kingman, Arizona in 1973; a liquid nitrogen tank rupture[6] at Air Products and Chemicals and Mobay Chemical Company at New Martinsville, West Virginia on January 31, 1978 [1];Texas City, Texas in 1978; Murdock, Illinois in 1983; San Juan Ixhuatepec, Mexico City in 1984; and Toronto, Ontario in 2008. -Safety measures[edit] -[icon] This section requires expansion.

The fuel-air bomb is one of the most well-known types of thermobaric weapons. -Most conventional explosives consist of a fuel-oxidizer premix (gunpowder, for example, contains 25% fuel and 75% oxidizer), whereas thermobaric weapons are almost 100% fuel, so thermobaric weapons are significantly more energetic than conventional condensed explosives of equal weight. Their reliance on atmospheric oxygen makes them unsuitable for use underwater, at high altitude, and in adverse weather. They do, however, cause considerably more destruction when used inside confined environments such as tunnels, caves, and bunkers - partly due to the sustained blast wave, and partly by consuming the available oxygen inside those confined spaces. -There are many different types of thermobaric weapons rounds that can be fitted to hand-held launchers.[1] -Contents [hide] -1 Terminology -2 Mechanism -2.1 Fuel-air explosive -2.1.1 Effect -3 Development history -3.1 Soviet and Russian developments -3.2 US developments -4 History -4.1 Military use -4.2 Non-military use -5 See also -6 References -7 External links -Terminology[edit] -The term thermobaric is derived from the Greek words for "heat" and "pressure": thermobarikos (θερμοβαρικός), from thermos (θερμός), hot + baros (βάρος), weight, pressure + suffix -ikos (-ικός), suffix -ic. -Other terms used for this family of weapons are high-impulse thermobaric weapons (HITs), heat and pressure weapons, vacuum bombs, or fuel-air explosives (FAE or FAX). -Mechanism[edit] -In contrast to condensed explosive, where oxidation in a confined region produces a blast front from essentially a point source, a flame front accelerates to a large volume producing pressure fronts both within the mixture of fuel and oxidant and then in the surrounding air.[2] -Thermobaric explosives apply the principles underlying accidental unconfined vapor cloud explosions, which include those from dispersions of flammable dusts and droplets.[3] Previously, such explosions were most often encountered in flour mills and their storage containers, and later in coal mines; but, now, most commonly in discharged oil tankers and refineries, including an incident at Buncefield in the UK in 2005 where the blast wave woke people 150 kilometres (93 mi) from its centre.[4] -A typical weapon consists of a container packed with a fuel substance, in the center of which is a small conventional-explosive "scatter charge". Fuels are chosen on the basis of the exothermicity of their oxidation, ranging from powdered metals, such as aluminium or magnesium, to organic materials, possibly with a self-contained partial oxidant. The most recent development involves the use of nanofuels.[5][6] -A thermobaric bomb's effective yield requires the most appropriate combination of a number of factors; among these are how well the fuel is dispersed, how rapidly it mixes with the surrounding atmosphere, and the initiation of the igniter and its position relative to the container of fuel. In some designs, strong munitions cases allow the blast pressure to be contained long enough for the fuel to be heated up well above its auto-ignition temperature, so that once the container bursts the super-heated fuel will auto-ignite progressively as it comes into contact with atmospheric oxygen.[7][8][9][10][11][12][13][14][15][16][17] -Conventional upper and lower limits of flammability apply to such weapons. Close in, blast from the dispersal charge, compressing and heating the surrounding atmosphere, will have some influence on the lower limit. The upper limit has been demonstrated strongly to influence the ignition of fogs above pools of oil.[18] This weakness may be eliminated by designs where the fuel is preheated well above its ignition temperature, so that its cooling during its dispersion still results in a minimal ignition delay on mixing. The continual combustion of the outer layer of fuel molecules as they come into contact with the air, generates additional heat which maintains the temperature of the interior of the fireball, and thus sustains the detonation.[19][20][21] -In confinement, a series of reflective shock waves are generated,[22][23] which maintain the fireball and can extend its duration to between 10 and 50 ms as exothermic recombination reactions occur.[24] Further damage can result as the gases cool and pressure drops sharply, leading to a partial vacuum. This effect has given rise to the misnomer "vacuum bomb". Piston-type afterburning is also believed to occur in such structures, as flame-fronts accelerate through it.[25][26] -Fuel-air explosive[edit] -A fuel-air explosive (FAE) device consists of a container of fuel and two separate explosive charges. After the munition is dropped or fired, the first explosive charge bursts open the container at a predetermined height and disperses the fuel in a cloud that mixes with atmospheric oxygen (the size of the cloud varies with the size of the munition). The cloud of fuel flows around objects and into structures. The second charge then detonates the cloud, creating a massive blast wave. The blast wave destroys unreinforced buildings and equipment and kills and injures people. The antipersonnel effect of the blast wave is more severe in foxholes, on people with body armor, and in enclosed spaces such as caves, buildings, and bunkers. -Fuel-air explosives were first developed, and used in Vietnam, by the United States. Soviet scientists, however, quickly developed their own FAE weapons, which were reportedly used against China in the Sino-Soviet border conflict and in Afghanistan. Since then, research and development has continued and currently Russian forces field a wide array of third-generation FAE warheads. -Effect[edit] -A Human Rights Watch report of 1 February 2000[27] quotes a study made by the US Defense Intelligence Agency: -The [blast] kill mechanism against living targets is unique–and unpleasant.... What kills is the pressure wave, and more importantly, the subsequent rarefaction [vacuum], which ruptures the lungs.... If the fuel deflagrates but does not detonate, victims will be severely burned and will probably also inhale the burning fuel. Since the most common FAE fuels, ethylene oxide and propylene oxide, are highly toxic, undetonated FAE should prove as lethal to personnel caught within the cloud as most chemical agents. -According to a U.S. Central Intelligence Agency study,[27] "the effect of an FAE explosion within confined spaces is immense. Those near the ignition point are obliterated. Those at the fringe are likely to suffer many internal, and thus invisible injuries, including burst eardrums and crushed inner ear organs, severe concussions, ruptured lungs and internal organs, and possibly blindness." Another Defense Intelligence Agency document speculates that because the "shock and pressure waves cause minimal damage to brain tissue…it is possible that victims of FAEs are not rendered unconscious by the blast, but instead suffer for several seconds or minutes while they suffocate."[28] -Development history[edit] -Soviet and Russian developments[edit] - -A RPO-A rocket and launcher. -The Soviet armed forces extensively developed FAE weapons,[29] such as the RPO-A, and used them in Chechnya.[30] -The Russian armed forces have developed thermobaric ammunition variants for several of their weapons, such as the TGB-7V thermobaric grenade with a lethality radius of 10 metres (33 ft), which can be launched from a RPG-7. The GM-94 is a 43 mm pump-action grenade launcher which is designed mainly to fire thermobaric grenades for close quarters combat. With the grenade weighing 250 grams (8.8 oz) and holding a 160 grams (5.6 oz) explosive mixture, its lethality radius is 3 metres (9.8 ft); however, due to the deliberate "fragmentation-free" design of the grenade, 4 metres (13 ft) is already considered a safe distance.[31] The RPO-A and upgraded RPO-M are infantry-portable RPGs designed to fire thermobaric rockets. The RPO-M, for instance, has a thermobaric warhead with a TNT equivalence of 5.5 kilograms (12 lb) of TNT and destructive capabilities similar to a 152 mm High explosive fragmentation artillery shell.[32][33] The RShG-1 and the RShG-2 are thermobaric variants of the RPG-27 and RPG-26 respectively. The RShG-1 is the more powerful variant, with its warhead having a 10 metres (33 ft) lethality radius and producing about the same effect as 6 kg (13 lb) of TNT.[34] The RMG is a further derivative of the RPG-26 that uses a tandem-charge warhead, whereby the precursor HEAT warhead blasts an opening for the main thermobaric charge to enter and detonate inside.[35] The RMG's precursor HEAT warhead can penetrate 300 mm of reinforced concrete or over 100 mm of Rolled homogeneous armour, thus allowing the 105 millimetres (4.1 in) diameter thermobaric warhead to detonate inside.[36] -The other examples include the SACLOS or millimeter wave radar-guided thermobaric variants of the 9M123 Khrizantema, the 9M133F-1 thermobaric warhead variant of the 9M133 Kornet, and the 9M131F thermobaric warhead variant of the 9K115-2 Metis-M, all of which are anti-tank missiles. The Kornet has since been upgraded to the Kornet-EM, and its thermobaric variant has a maximum range of 10 kilometres (6.2 mi) and has the TNT equivalent of 7 kilograms (15 lb) of TNT.[37] The 300 mm 9M55S thermobaric cluster warhead rocket was built to be fired from the BM-30 Smerch MLRS. A dedicated carrier of thermobaric weapons is the purpose-built TOS-1, a 24-tube MLRS designed to fire 220 mm caliber thermobaric rockets. A full salvo from the TOS-1 will cover a rectangle 200x400 metres.[38] The Iskander-M theatre ballistic missile can also carry a 700 kilograms (1,500 lb) thermobaric warhead.[39] - -The fireball blast from the Russian Air Force's FOAB, the largest Thermobaric device to be detonated. -Many Russian Air Force munitions also have thermobaric variants. The 80 mm S-8 rocket has the S-8DM and S-8DF thermobaric variants. The S-8's larger 122 mm brother, the S-13 rocket, has the S-13D and S-13DF thermobaric variants. The S-13DF's warhead weighs only 32 kg (71 lb) but its power is equivalent to 40 kg (88 lb) of TNT. The KAB-500-OD variant of the KAB-500KR has a 250 kg (550 lb) thermobaric warhead. The ODAB-500PM and ODAB-500PMV unguided bombs carry a 190 kg (420 lb) fuel-air explosive each. The KAB-1500S GLONASS/GPS guided 1,500 kg (3,300 lb) bomb also has a thermobaric variant. Its fireball will cover over a 150-metre (490 ft) radius and its lethality zone is a 500-metre (1,600 ft) radius.[40] The 9M120 Ataka-V and the 9K114 Shturm ATGMs both have thermobaric variants. -In September 2007 Russia exploded the largest thermobaric weapon ever made. The weapon's yield was reportedly greater than that of the smallest dial-a-yield nuclear weapons at their lowest settings.[41][42] Russia named this particular ordnance the "Father of All Bombs" in response to the United States developed "Massive Ordnance Air Blast" (MOAB) bomb whose backronym is the "Mother of All Bombs", and which previously held the accolade of the most powerful non-nuclear weapon in history.[43] The bomb contains an about 7 tons charge of a liquid fuel such as ethylene oxide, mixed with an energetic nanoparticle such as aluminium, surrounding a high explosive burster[44] that when detonated created an explosion equivalent to 44 metric tons of TNT. -US developments[edit] - -A BLU-72/B bomb on a USAF A-1E taking off from Nakhon Phanom, in September 1968. -Current US FAE munitions include: -BLU-73 FAE I -BLU-95 500-lb (FAE-II) -BLU-96 2,000-lb (FAE-II) -CBU-55 FAE I -CBU-72 FAE I -The XM1060 40-mm grenade is a small-arms thermobaric device, which was delivered to U.S. forces in April 2003.[45] Since the 2003 Invasion of Iraq, the US Marine Corps has introduced a thermobaric 'Novel Explosive' (SMAW-NE) round for the Mk 153 SMAW rocket launcher. One team of Marines reported that they had destroyed a large one-story masonry type building with one round from 100 yards (91 m).[46] -The AGM-114N Hellfire II, first used by U.S. forces in 2003 in Iraq, uses a Metal Augmented Charge (MAC) warhead that contains a thermobaric explosive fill using fluoridated aluminium layered between the charge casing and a PBXN-112 explosive mixture. When the PBXN-112 detonates, the aluminium mixture is dispersed and rapidly burns. The resultant sustained high pressure is extremely effective against people and structures.[47] -History[edit] -Military use[edit] - -US Navy BLU-118B being prepared for shipping for use in Afghanistan, 5 March 2002. -The first experiments with thermobaric weapon were conducted in Germany during World War II and were led by Mario Zippermayr. The German bombs used coal dust as fuel and were extensively tested in 1943 and 1944, but did not reach mass production before the war ended. -The TOS-1 system was test fired in Panjshir valley during Soviet war in Afghanistan in the early 1980s.[48] -Unconfirmed reports suggest that Russian military forces used ground delivered thermobaric weapons in the storming of the Russian parliament during the 1993 Russian constitutional crisis and also during the Battle for Grozny (first and second Chechen wars) to attack dug in Chechen fighters. The use of both TOS-1 heavy MLRS and "RPO-A Shmel" shoulder-fired rocket system in the Chechen wars is reported to have occurred.[48][49] -It is theorized that a multitude of hand-held thermobaric weapons were used by the Russian Armed Forces in their efforts to retake the school during the 2004 Beslan school hostage crisis. The RPO-A and either the TGB-7V thermobaric rocket from the RPG-7 or rockets from either the RShG-1 or the RShG-2 is claimed to have been used by the Spetsnaz during the initial storming of the school.[50][51][52] At least 3 and as many as 9 RPO-A casings were later found at the positions of the Spetsnaz.[53][54] The Russian Government later admitted to the use of the RPO-A during the crisis.[55] -According to UK Ministry of Defence, British military forces have also used thermobaric weapons in their AGM-114N Hellfire missiles (carried by Apache helicopters and UAVs) against the Taliban in the War in Afghanistan.[56] -The US military also used thermobaric weapons in Afghanistan. On 3 March 2002, a single 2,000 lb (910 kg) laser guided thermobaric bomb was used by the United States Army against cave complexes in which Al-Qaeda and Taliban fighters had taken refuge in the Gardez region of Afghanistan.[57][58] The SMAW-NE was used by the US Marines during the First Battle of Fallujah and Second Battle of Fallujah. -Reports by the rebel fighters of the Free Syrian Army claim the Syrian Air Force used such weapons against residential area targets occupied by the rebel fighters, as for instance in the Battle for Aleppo[59] and also in Kafar Batna.[60] A United Nations panel of human rights investigators reported that the Syrian government used thermobaric bombs against the rebellious town of Qusayr in March 2013.[61] -Non-military use[edit] -Thermobaric and fuel-air explosives have been used in guerrilla warfare since the 1983 Beirut barracks bombing in Lebanon, which used a gas-enhanced explosive mechanism, probably propane, butane or acetylene.[62] The explosive used by the bombers in the 1993 World Trade Center bombing incorporated the FAE principle, using three tanks of bottled hydrogen gas to enhance the blast.[63][64] Jemaah Islamiyah bombers used a shock-dispersed solid fuel charge,[65] based on the thermobaric principle,[66] to attack the Sari nightclub in the 2002 Bali bombings.[67] -See also[edit] -Bunker buster -Dust explosion -FOAB -Flame fougasse -MOAB -RPO-A -SMAW -References[edit] -Jump up ^ Algeria Isp (2011-10-18).

American Quarter (diameter 24 mm) for comparison. -Gunpowder, also known as black powder, is a chemical explosive—the earliest known. It is a mixture of sulfur, charcoal, and potassium nitrate (saltpeter). The sulfur and charcoal act as fuels, and the saltpeter is an oxidizer.[2][3] Because of its burning properties and the amount of heat and gas volume that it generates, gunpowder has been widely used as a propellant in firearms and as a pyrotechnic composition in fireworks. -Gunpowder is assigned the UN number UN0027 and has a hazard class of 1.1D. It has a flash point of approximately 427–464 °C (801–867 °F). The specific flash point may vary based on the specific composition of the gunpowder. Gunpowder's gravity is 1.70–1.82 (mercury method) orŠ 1.92–2.08 (pycnometer), and it has a pH of 6.0–8.0. It is also considered to be an insoluble material.[4] -Gunpowder was, according to prevailing academic consensus, invented in the 9th century in China,[5][6] and the earliest record of a written formula for gunpowder appears in the 11th century Song Dynasty text, Wujing Zongyao.[7] This discovery led to the invention of fireworks and the earliest gunpowder weapons in China. In the centuries following the Chinese discovery, gunpowder weapons began appearing in the Muslim world, Europe, and India. The technology spread from China through the Middle East or Central Asia, and then into Europe.[8] The earliest Western accounts of gunpowder appear in texts written by English philosopher Roger Bacon in the 13th century.[9] -Gunpowder is classified as a low explosive because of its relatively slow decomposition rate and consequently low brisance. Low explosives deflagrate (i.e., burn) at subsonic speeds, whereas high explosives detonate, producing a supersonic wave. Gunpowder's burning rate increases with pressure, so it bursts containers if contained but otherwise just burns in the open. Ignition of the powder packed behind a bullet must generate enough pressure to force it from the muzzle at high speed, but not enough to rupture the gun barrel. Gunpowder thus makes a good propellant, but is less suitable for shattering rock or fortifications. Gunpowder was widely used to fill artillery shells and in mining and civil engineering to blast rock roughly until the second half of the 19th century, when the first high explosives (nitro-explosives) were discovered. Gunpowder is no longer used in modern explosive military warheads, nor is it used as main explosive in mining operations due to its cost relative to that of newer alternatives such as ammonium nitrate/fuel oil (ANFO).[10] Black powder is still used as a delay element in various munitions where its slow-burning properties are valuable. -Formulations used in blasting rock (such as in quarrying) are called blasting powder. -Contents [hide] -1 History -1.1 China -1.2 Middle East -1.3 Mainland Europe -1.4 Britain and Ireland -1.5 India -1.6 Indonesia -2 Manufacturing technology -3 Composition and characteristics -4 Serpentine -5 Corning -6 Modern types -7 Other types of gunpowder -8 Sulfur-free gunpowder -9 Combustion characteristics -9.1 Advantages -9.2 Disadvantages -9.3 Transportation -10 Other uses -11 See also -12 References -13 External links -History[edit] - -Early Chinese rocket - -A Mongol bomb thrown against a charging Japanese samurai during the Mongol invasions of Japan after founding the Yuan Dynasty, 1281. -Main article: History of gunpowder -Gunpowder was invented in China while taoists attempted to create a potion of immortality. Chinese military forces used gunpowder-based weapons (i.e. rockets, guns, cannons) and explosives (i.e. grenades and different types of bombs) against the Mongols when the Mongols attempted to invade and breach city fortifications on China's northern borders. After the Mongols conquered China and founded the Yuan Dynasty, they used the Chinese gunpowder-based weapons technology in their attempted invasion of Japan; they also used gunpowder to fuel rockets. -The mainstream scholarly consensus is that gunpowder was invented in China, spread through the Middle East, and then into Europe,[8] although there is a dispute over how much the Chinese advancements in gunpowder warfare influenced later advancements in the Middle East and Europe.[11][12] The spread of gunpowder across Asia from China is widely attributed to the Mongols. One of the first examples of Europeans encountering gunpowder and firearms is at the Battle of Mohi in 1241. At this battle the Mongols not only used gunpowder in early Chinese firearms but in the earliest grenades as well. -A major problem confronting the study of the early history of gunpowder is ready access to sources close to the events described. Often enough, the first records potentially describing use of gunpowder in warfare were written several centuries after the fact, and may well have been colored by the contemporary experiences of the chronicler.[13] It is also difficult to accurately translate original alchemy texts, especially medieval Chinese texts that try to explain phenomena through metaphor, into modern scientific language with rigidly defined terminology. The translation difficulty has led to errors or loose interpretations bordering on artistic licence.[14][15] Early writings potentially mentioning gunpowder are sometimes marked by a linguistic process where old words acquired new meanings.[16] For instance, the Arabic word naft transitioned from denoting naphtha to denoting gunpowder, and the Chinese word pao evolved from meaning catapult to referring to cannon.[17] According to science and technology historian Bert S. Hall: "It goes without saying, however, that historians bent on special pleading, or simply with axes of their own to grind, can find rich material in these terminological thickets."[18] -China[edit] -Further information: Wujing Zongyao, Four Great Inventions and List of Chinese inventions - -Chinese Ming Dynasty (1368-1644) matchlock firearms -Saltpeter was known to the Chinese by the mid-1st century AD and there is strong evidence of the use of saltpeter and sulfur in various largely medicinal combinations.[19] A Chinese alchemical text dated 492 noted saltpeter burnt with a purple flame, providing a practical and reliable means of distinguishing it from other inorganic salts, thus enabling alchemists to evaluate and compare purification techniques; the earliest Latin accounts of saltpeter purification are dated after 1200.[20] - -Yuan Dynasty bronze hand cannon from 1332 at th (c. 808); it describes mixing six parts sulfur to six parts saltpeter to one part birthwort herb (which would provide carbon).[21] -The first reference to the incendiary properties of such mixtures is the passage of the Zhenyuan miaodao yaolüe, a Taoist text tentatively dated to the mid-9th century AD:[20] "Some have heated together sulfur, realgar and saltpete with honey; smoke and flames result, so that their hands and faces have been burnt, and even the whole house where they were working burned down."[22] The Chinese word for "gunpowder" is Chinese: 火药/火藥; pinyin: huŏ yào /xuou yɑʊ/, which literally means "Fire Medicine";[23] however this name only came into use some centuries after the mixture's discovery.[24] During the 9th century, Taoist monks or alchemists searching for an elixir of immortality had serendipitously stumbled upon gunpowder.[8][25] The Chinese wasted little time in applying gunpowder to the development of weapons, and in the centuries that followed, they produced a variety of gunpowder weapons, including flamethrowers, rockets, bombs, and land mines, before inventing guns as a projectile weapon.[26] Archaeological evidence of a hand cannon has been excavated in Manchuria dated from the late 1200s[27] and the shells of explosive bombs have been discovered in a shipwreck off the shore of Japan dated from 1281, during the Mongol invasions of Japan.[28] -The Chinese "Wu Ching Tsung Yao" (Complete Essentials from the Military Classics), written by Tseng Kung-Liang between 1040–1044, provides encyclopedia references to a variety of mixtures that included petrochemicals—as well as garlic and honey. A slow match for flame throwing mechanisms using the siphon principle and for fireworks and rockets are mentioned. The mixture formulas in this book do not contain enough saltpeter to create an explosive however; being limited to at most 50% saltpeter, they produce an incendiary.[29] The Essentials was however written by a Song Dynasty court bureaucrat, and there's little evidence that it had any immediate impact on warfare; there is no mention of gunpowder use in the chronicles of the wars against the Tanguts in the eleventh century, and China was otherwise mostly at peace during this century. The first chronicled use of "fire spears" (or "fire lances") is at the siege of De'an in 1132.[30] - -Formula for gunpowder in 1044 Wujing zongyao part I vol 12 - - -Instruction for fire bomb in Wujing zongyao - - -Fire bomb - - -Fire grenade - - -Proto-cannon from the Ming Dynasty text Huolongjing - - -Land mine from the Ming Dynasty text Huolongjing - - -Fire arrow rocket launcher from the Wujing zongyao -Middle East[edit] -Main articles: Inventions in the Islamic world and Alchemy and chemistry in Islam - -The Sultani Cannon, a very heavy bronze breech-loading cannon of type used by Ottoman Empire in the conquest of Constantinople, in 1453. -The Muslims acquired knowledge of gunpowder some time between 1240 and 1280, by which time the Syrian Hasan al-Rammah had written, in Arabic, recipes for gunpowder, instructions for the purification of saltpeter, and descriptions of gunpowder incendiaries. Gunpowder arrived in the Middle East, possibly through India, from China. This is implied by al-Rammah's usage of "terms that suggested he derived his knowledge from Chinese sources" and his references to saltpeter as "Chinese snow" Arabic: ثلج الصين‎ thalj al-ṣīn, fireworks as "Chinese flowers" and rockets as "Chinese arrows".[31] However, because al-Rammah attributes his material to "his father and forefathers", al-Hassan argues that gunpowder became prevalent in Syria and Egypt by "the end of the twelfth century or the beginning of the thirteenth".[32] Persians called saltpeter "Chinese salt" [33][34][35][36][37] or "salt from Chinese salt marshes" (namak shūra chīnī Persian: نمک شوره چيني‎).[38][39] - -A picture of a 15th-century Granadian cannon from the book Al-izz wal rifa'a. -Al-Hassan claims that in the Battle of Ain Jalut of 1260, the Mamluks used against the Mongols in "the first cannon in history" gunpowder formula with near-identical ideal composition ratios for explosive gunpowder.[32] Other historians urge caution regarding claims of Islamic firearms use in the 1204-1324 period as late medieval Arabic texts used the same word for gunpowder, naft, that they used for an earlier incendiary, naphtha.[13][17] Khan claims that it was invading Mongols who introduced gunpowder to the Islamic world[40] and cites Mamluk antagonism towards early musketeers in their infantry as an example of how gunpowder weapons were not always met with open acceptance in the Middle East.[41] Similarly, the refusal of their Qizilbash forces to use firearms contributed to the Safavid rout at Chaldiran in 1514.[41] -The earliest surviving documentary evidence for the use of the hand cannon, considered the oldest type of portable firearm and a forerunner of the handgun, are from several Arabic manuscripts dated to the 14th century.[42] Al-Hassan argues that these are based on earlier originals and that they report hand-held cannons being used by the Mamluks at the Battle of Ain Jalut in 1260.[32] -Hasan al-Rammah included 107 gunpowder recipes in his text al-Furusiyyah wa al-Manasib al-Harbiyya (The Book of Military Horsemanship and Ingenious War Devices), 22 of which are for rockets. If one takes the median of 17 of these 22 compositions for rockets (75% nitrates, 9.06% sulfur, and 15.94% carbon), it is nearly identical to the modern reported ideal gunpowder recipe of 75% potassium nitrate, 10% sulfur, and 15% carbon.[32] -The state-controlled manufacture of gunpowder by the Ottoman Empire through early supply chains to obtain nitre, sulfur and high-quality charcoal from oaks in Anatolia contributed significantly to its expansion the 15th and 18th century. It was not until later in the 19th century when the syndicalist production of Turkish gunpowder was greatly reduced, which coincided with the decline of its military might.[43] -Mainland Europe[edit] -Several sources mention Chinese firearms and gunpowder weapons being deployed by the Mongols against European forces at the Battle of Mohi in 1241.[44][45][46] Professor Kenneth Warren Chase credits the Mongols for introducing into Europe gunpowder and its associated weaponry.[47] -C. F. Temler interprets Peter, Bishop of Leon, as reporting the use of cannons in Seville in 1248.[48] -In Europe, one of the first mentions of gunpowder use appears in a passage found in Roger Bacon's Opus Maius and Opus Tertium in what has been interpreted as being firecrackers. The most telling passage reads: "We have an example of these things (that act on the senses) in [the sound and fire of] that children's toy which is made in many [diverse] parts of the world; i.e., a device no bigger than one's thumb. From the violence of that salt called saltpeter [together with sulfur and willow charcoal, combined into a powder] so horrible a sound is made by the bursting of a thing so small, no more than a bit of parchment [containing it], that we find [the ear assaulted by a noise] exceeding the roar of strong thunder, and a flash brighter than the most brilliant lightning."[9] In the early 20th century, British artillery officer Henry William Lovett Hime proposed that another work tentatively attributed to Bacon, Epistola de Secretis Operibus Artis et Naturae, et de Nullitate Magiae contained an encrypted formula for gunpowder. This claim has been disputed by historians of science including Lynn Thorndike, John Maxson Stillman and George Sarton and by Bacon's editor Robert Steele, both in terms of authenticity of the work, and with respect to the decryption method.[9] In any case, the formula claimed to have been decrypted (7:5:5 saltpeter:charcoal:sulfur) is not useful for firearms use or even firecrackers, burning slowly and producing mostly smoke.[49][50] - -Cannon forged in 1667 at the Fortín de La Galera, Nueva Esparta, Venezuela. -The Liber Ignium, or Book of Fires, attributed to Marcus Graecus, is a collection of incendiary recipes, including some gunpowder recipes. Partington dates the gunpowder recipes to approximately 1300.[51] One recipe for "flying fire" (ingis volatilis) involves saltpeter, sulfur, and colophonium, which, when inserted into a reed or hollow wood, "flies away suddenly and burns up everything." Another recipe, for artificial "thunder", specifies a mixture of one pound native sulfur, two pounds linden or willow charcoal, and six pounds of saltpeter.[52] Another specifies a 1:3:9 ratio.[52] -Some of the gunpowder recipes of De Mirabilibus Mundi of Albertus Magnus are identical to the recipes of the Liber Ignium, and according to Partington, "may have been taken from that work, rather than conversely."[53] Partington suggests that some of the book may have been compiled by Albert's students, "but since it is found in thirteenth century manuscripts, it may well be by Albert."[53] Albertus Magnus died in 1280. -A common German folk-tale is of the German priest/monk named Berthold Schwarz who independently invented gunpowder, thus earning it the German name Schwarzpulver or in English Schwarz's powder. Schwarz is also German for black so this folk-tale, while likely containing elements of truth, is considered problematic. -A major advance in manufacturing began in Europe in the late 14th century when the safety and thoroughness of incorporation was improved by wet grinding; liquid, such as distilled spirits or perhaps the urine of wine-drinking bishops[54] was added during the grinding-together of the ingredients and the moist paste dried afterwards. (The principle of wet mixing to prevent the separation of dry ingredients, invented for gunpowder, is used today in the pharmaceutical industry.[55]) It was also discovered that if the paste was rolled into balls before drying the resulting gunpowder absorbed less water from the air during storage and traveled better. The balls were then crushed in a mortar by the gunner immediately before use, with the old problem of uneven particle size and packing causing unpredictable results. -If the right size particles were chosen, however, the result was a great improvement in power. Forming the damp paste into corn-sized clumps by hand or with the use of a sieve instead of larger balls produced a product after drying that loaded much better, as each tiny piece provided its own surrounding air space that allowed much more rapid combustion than a fine powder. This "corned" gunpowder was from 30% to 300% more powerful. An example is cited where 34 pounds of serpentine was needed to shoot a 47 pound ball, but only 18 pounds of corned powder.[54] The optimum size of the grain depended on its use; larger for large cannon, finer for small arms. Larger cast cannons were easily muzzle-loaded with corned powder using a long-handled ladle. Corned powder also retained the advantage of low moisture absorption, as even tiny grains still had much less surface area to attract water than a floury powder. -During this time, European manufacturers also began regularly purifying saltpeter, using wood ashes containing potassium carbonate to precipitate calcium from their dung liquor, and using ox blood, alum, and slices of turnip to clarify the solution.[54] -Gunpowder-making and metal-smelting and casting for shot and cannon fee was closely held by skilled military tradesmen, who formed guilds that collected dues, tested apprentices, and gave pensions. "Fire workers" were also required to craft fireworks for celebrations of victory or peace. During the Renaissance, two European schools of pyrotechnic thought emerged, one in Italy and the other at Nuremberg, Germany. Vannoccio Biringuccio, born in 1480, was a member of the guild Fraternita di Santa Barbara but broke with the tradition of secrecy by setting down everything he knew in a book titled De la pirotechnia, written in vernacular. The first printed book on either gunpowder or metalworking, it was published posthumously in 1540, with 9 editions over 138 years, and also reprinted by MIT Press in 1966.[54] By the mid-17th century fireworks were used for entertainment on an unprecedented scale in Europe, being popular even at resorts and public gardens.[56] -In 1774 Louis XVI ascended to the throne of France at age 20. After he discovered that France was not self-sufficient in gunpowder, a Gunpowder Administration was established; to head it, the lawyer Antoine Lavoisier was appointed. Although from a bourgeois family, after his degree in law Lavoisier became wealthy from a company set up to collect taxes for the Crown; this allowed him to pursue experimental natural science as a hobby.[57] -Without access to cheap Indian saltpeter (controlled by the British), for hundreds of years France had relied on saltpetermen with royal warrants, the droit de fouille or "right to dig", to seize nitrous-containing soil and demolished walls of barnyards, without compensation to the owners.[58] This caused farmers, the wealthy, or entire villages to bribe the petermen and the associated bureaucracy to leave their buildings alone and the saltpeter uncollected. Lavoisier instituted a crash program to increase saltpeter production, revised (and later eliminated) the droit de fouille, researched best refining and powder manufacturing methods, instituted management and record-keeping, and established pricing that encouraged private investment in works. Although saltpeter from new Prussian-style putrefaction works had not been produced yet (the process taking about 18 months), in only a year France had gunpowder to export. A chief beneficiary of this surplus was the American Revolution. By careful testing and adjusting the proportions and grinding time, powder from mills such as at Essonne outside Paris became the best in the world by 1788, and inexpensive.[58] [59] -Britain and Ireland[edit] - -The old Powder or Pouther magazine dating from 1642, built by order of Charles I. Irvine, North Ayrshire, Scotland -Gunpowder production in Britain appears to have started in the mid 14th century AD with the aim of supplying the English Crown.[60] Records show that gunpowder was being made, in England, in 1346, at the Tower of London; a powder house existed at the Tower in 1461; and in 1515 three King's gunpowder makers worked there.[60] Gunpowder was also being made or stored at other Royal castles, such as Portchester. By the early 14th century, according to N.J.G. Pounds's study The Medieval Castle in England and Wales, many English castles had been deserted and others were crumbling. Their military significance faded except on the borders. Gunpowder had made smaller castles useless.[61] -Henry VIII of England was short of gunpowder when he invaded France in 1544 and England needed to import gunpowder via the port of Antwerp in what is now Belgium.[60] -The English Civil War (1642–1645) led to an expansion of the gunpowder industry, with the repeal of the Royal Patent in August 1641.[60] -Two British physicists, Andrew Noble and Frederick Abel, worked to improve the properties of black powder during the late 19th century. This formed the basis for the Noble-Abel gas equation for internal ballistics.[62] -The introduction of smokeless powder in the late 19th century led to a contraction of the gunpowder industry. After the end of World War I, the majority of the United Kingdom gunpowder manufacturers merged into a single company, "Explosives Trades limited"; and number of sites were closed down, including those in Ireland. This company became Nobel Industries Limited; and in 1926 became a founding member of Imperial Chemical Industries. The Home Office removed gunpowder from its list of Permitted Explosives; and shortly afterwards, on 31 December 1931, the former Curtis & Harvey's Glynneath gunpowder factory at Pontneddfechan, in Wales, closed down, and it was demolished by fire in 1932.[63] - -Gunpowder storing barrels at Martello tower in Point Pleasant Park -The last remaining gunpowder mill at the Royal Gunpowder Factory, Waltham Abbey was damaged by a German parachute mine in 1941 and it never reopened.[64] This was followed by the closure of the gunpowder section at the Royal Ordnance Factory, ROF Chorley, the section was closed and demolished at the end of World War II; and ICI Nobel's Roslin gunpowder factory, which closed in 1954.[64][65] -This left the sole United Kingdom gunpowder factory at ICI Nobel's Ardeer site in Scotland; it too closed in October 1976.[64] Since then gunpowder has been imported into the United Kingdom. In the late 1970s/early 1980s gunpowder was bought from eastern Europe, particularly from what was then the German Democratic Republic and former Yugoslavia. -India[edit] - -In the year 1780 the British began to annex the territories of the Sultanate of Mysore, during the Second Anglo-Mysore War. The British battalion was defeated during the Battle of Guntur, by the forces of Hyder Ali, who effectively utilized Mysorean rockets and Rocket artillery against the closely massed British forces. - -Mughal Emperor Shah Jahan, hunting deer using a Matchlock as the sun sets in the horizon. -Gunpowder and gunpowder weapons were transmitted to India through the Mongol invasions of India.[66][67] The Mongols were defeated by Alauddin Khilji of the Delhi Sultanate, and some of the Mongol soldiers remained in northern India after their conversion to Islam.[67] It was written in the Tarikh-i Firishta (1606–1607) that Nasir ud din Mahmud the ruler of the Delhi Sultanate presented the envoy of the Mongol ruler Hulegu Khan with a dazzling pyrotechnics display upon his arrival in Delhi in 1258 AD. Nasir ud din Mahmud tried to express his strength as a ruler and tried to ward off any Mongol attempt similar to the Siege of Baghdad (1258).[68] Firearms known as top-o-tufak also existed in many Muslim kingdoms in India by as early as 1366 AD.[68] From then on the employment of gunpowder warfare in India was prevalent, with events such as the "Siege of Belgaum" in 1473 by Sultan Muhammad Shah Bahmani.[69] -The shipwrecked Ottoman Admiral Seydi Ali Reis is known to have introduced the earliest type of Matchlock weapons, which the Ottomans used against the Portuguese during the Siege of Diu (1531). After that, a diverse variety of firearms; large guns in particular, became visible in Tanjore, Dacca, Bijapur, and Murshidabad.[70] Guns made of bronze were recovered from Calicut (1504)- the former capital of the Zamorins[71] -The Mughal Emperor Akbar mass-produced matchlocks for the Mughal Army. Akbar is personally known to have shot a leading Rajput commander during the Siege of Chittorgarh.[72] The Mughals began to use Bamboo rockets (mainly for signalling) and employ Sappers: special units that undermined heavy stone fortifications to plant gunpowder charges. -The Mughal Emperor Shah Jahan is known to have introduced much more advanced Matchlocks, their designs were a combination of Ottoman and Mughal designs. Shah Jahan also countered the British and other Europeans in his province of Gujarāt, which supplied Europe saltpeter for use in gunpowder warfare during the 17th century.[73] Bengal and Mālwa participated in saltpeter production.[73] The Dutch, French, Portuguese, and English used Chhapra as a center of saltpeter refining.[73] -Ever since the founding of the Sultanate of Mysore by Hyder Ali, French military officers were employed to train the Mysore Army. Hyder Ali and his son Tipu Sultan were the first to introduce modern Cannons and Muskets, their army was also the first in India to have official uniforms. During the Second Anglo-Mysore War Hyder Ali and his son Tipu Sultan unleashed the Mysorean rockets at their British opponents effectively defeating them on various occasions. The Mysorean rockets inspired the development of the Congreve rocket, which the British widely utilized during the Napoleonic Wars and the War of 1812.[74] -Indonesia[edit] -The Javanese Majapahit Empire was arguably able to encompass much of modern day Indonesia due to its unique mastery of bronze smithing and use of a central arsenal fed by a large number of cottage industries within the immediate region. Documentary and archeological evidence indicate that Arab or Indian traders introduced gunpowder, gonnes, muskets, blunderbusses, and cannons to the Javanese, Acehnese, and Batak via long established commercial trade routes around the early to mid 14th century CE.[75] Portuguese and Spanish invaders were unpleasantly surprised and occasionally even outgunned on occasion.[76] The resurgent Singhasari Empire overtook Sriwijaya and later emerged as the Majapahit whose warfare featured the use of fire-arms and cannonade.[77] Circa 1540 CE the Javanese, always alert for new weapons found the newly arrived Portuguese weaponry superior to that of the locally made variants. Javanese bronze breech-loaded swivel-guns, known as meriam, or erroneously as lantaka, was used widely by the Majapahit navy as well as by pirates and rival lords. The demise of the Majapahit empire and the dispersal of disaffected skilled bronze cannon-smiths to Brunei, modern Sumatra, Malaysia and the Philippines lead to widespread use, especially in the Makassar Strait. -Saltpeter harvesting was recorded by Dutch and German travelers as being common in even the smallest villages and was collected from the decomposition process of large dung hills specifically piled for the purpose. The Dutch punishment for possession of non-permitted gunpowder appears to have been amputation.[78] Ownership and manufacture of gunpowder was later prohibited by the colonial Dutch occupiers.[75] According to a colonel McKenzie quoted in Sir Thomas Stamford Raffles, The History of Java (1817), the purest sulfur was supplied from a crater from a mountain near the straits of Bali.[77] -Manufacturing technology[edit] - -Edge-runner mill in a restored mill, at Eleutherian Mills -For the most powerful black powder meal, a wood charcoal is used. The best wood for the purpose is Pacific willow,[79] but others such as alder or buckthorn can be used. In Great Britain between the 15th to 19th centuries charcoal from alder buckthorn was greatly prized for gunpowder manufacture; cottonwood was used by the American Confederate States.[80] The ingredients are reduced in particle size and mixed as intimately as possible. Originally this was with a mortar-and-pestle or a similarly operating stamping-mill, using copper, bronze or other non-sparking materials, until supplanted by the rotating ball mill principle with non-sparking bronze or lead. Historically, a marble or limestone edge runner mill, running on a limestone bed was used in Great Britain; however, by the mid 19th century AD this had changed to either an iron shod stone wheel or a cast iron wheel running on an iron bed.[81] The mix was dampened with alcohol or water during grinding to prevent accidental ignition. This also helps the extremely soluble saltpeter mix into the microscopic nooks and crannies of the very high surface-area charcoal. -Around the late 14th century AD, European powdermakers first began adding liquid during grinding to improve mixing, reduce dust, and with it the risk of explosion.[82] The powder-makers would then shape the resulting paste of dampened gunpowder, known as mill cake, into corns, or grains, to dry. Not only did corned powder keep better because of its reduced surface area, gunners also found that it was more powerful and easier to load into guns. Before long, powder-makers standardized the process by forcing mill cake through sieves instead of corning powder by hand. -The improvement was based on reducing the surface area of a higher density composition. At the beginning of the 19th century, makers increased density further by static pressing. They shoveled damp mill cake into a two-foot square box, placed this beneath a screw press and reduced it to 1/2 its volume. "Presscake" had the hardness of slate. They broke the dried slabs with hammers or rollers, and sorted the granules with sieves into different grades. In the United States, Irenee du Pont, who had learned the trade from Lavoisier, tumbled the dried grains in rotating barrels to round the edges and increase durability during shipping and handling. (Sharp grains rounded off in transport, producing fine "meal dust" that changed the burning properties.) -Another advance was the manufacture of kiln charcoal by distilling wood in heated iron retorts instead of burning it in earthen pits. Controlling the temperature influenced the power and consistency of the finished gunpowder. In 1863, in response to high prices for Indian saltpeter, DuPont chemists developed a process using potash or mined potassium chloride to convert plentiful Chilean sodium nitrate to potassium nitrate.[83] -During the 18th century gunpowder factories became increasingly dependent on mechanical energy.[84] Despite mechanization, production difficulties related to humidity control, especially during the pressing, were still present in the late 19th century. A paper from 1885 laments that "Gunpowder is such a nervous and sensitive spirit, that in almost every process of manufacture it changes under our hands as the weather changes." Pressing times to the desired density could vary by factor of three depending on the atmospheric humidity.[85] -Composition and characteristics[edit] -The term black powder was coined in the late 19th century, primarily in the United States, to distinguish prior gunpowder formulations from the new smokeless powders and semi-smokeless powders, in cases where these are not referred to as cordite. Semi-smokeless powders featured bulk volume properties that approximated black powder, but had significantly reduced amounts of smoke and combustion products. Smokeless powder has different burning properties (pressure vs. time) and can generate higher pressures and work per gram. This can rupture older weapons designed for black powder. Smokeless powders ranged in color from brownish tan to yellow to white. Most of the bulk semi-smokeless powders ceased to be manufactured in the 1920s.[86][87][88] -Black powder is a granular mixture of -a nitrate, typically potassium nitrate (KNO3), which supplies oxygen for the reaction; -charcoal, which provides carbon and other fuel for the reaction, simplified as carbon (C); -sulfur (S), which, while also serving as a fuel, lowers the temperature required to ignite the mixture, thereby increasing the rate of combustion. -Potassium nitrate is the most important ingredient in terms of both bulk and function because the combustion process releases oxygen from the potassium nitrate, promoting the rapid burning of the other ingredients.[89] To reduce the likelihood of accidental ignition by static electricity, the granules of modern black powder are typically coated with graphite, which prevents the build-up of electrostatic charge. -Charcoal does not consist of pure carbon; rather, it consists of partially pyrolyzed cellulose, in which the wood is not completely decomposed. Carbon differs from charcoal. Whereas charcoal's autoignition temperature is relatively low, carbon's is much greater. Thus, a black powder composition containing pure carbon would burn similarly to a match head, at best.[90] -The current standard composition for the black powders that are manufactured by pyrotechnicians was adopted as long ago as 1780. Proportions by weight are 75% potassium nitrate (known as saltpeter or saltpetre), 15% softwood charcoal, and 10% sulfur.[81] These ratios have varied over the centuries and by country, and can be altered somewhat depending on the purpose of the powder. For instance, power grades of black powder, unsuitable for use in firearms but adequate for blasting rock in quarrying operations, is called blasting powder rather than gunpowder with standard proportions of 70% nitrate, 14% charcoal, and 16% sulfur; blasting powder may be made with the cheaper sodium nitrate substituted for potassium nitrate and proportions may be as low as 40% nitrate, 30% charcoal, and 30% sulfur.[91] In 1857, Lamont DuPont solved the main problem of using cheaper sodium nitrate formulations when he patented DuPont "B" Blasting powder. After manufacturing grains from press-cake in the usual way, his process tumbled the powder with graphite dust for 12 hours. This formed a graphite coating on each grain that reduced its ability to absorb moisture.[92] -French war powder in 1879 used the ratio 75% saltpeter, 12.5% charcoal, 12.5% sulfur. English war powder in 1879 used the ratio 75% saltpeter, 15% charcoal, 10% sulfur.[93] The British Congreve rockets used 62.4% saltpeter, 23.2% charcoal and 14.4% sulfur, but the British Mark VII gunpowder was changed to 65% saltpeter, 20% charcoal and 15% sulfur.[94] The explanation for the wide variety in formulation relates to usage. Powder used for rocketry can use a slower burn rate since it accelerates the projectile for a much longer time—whereas powders for weapons such as flintlocks, cap-locks, or matchlocks need a higher burn rate to accelerate the projectile in a much shorter distance. Cannons usually used lower burn rate powders, because most would burst with higher burn rate powders. -Serpentine[edit] -The original dry-compounded powder used in fifteenth-century Europe was known as "Serpentine", either a reference to Satan[95] or to a common artillery piece that used it.[96] The ingredients were ground together with a mortar and pestle, perhaps for 24 hours,[96] resulting in a fine flour. Vibration during transportation could cause the components to separate again, requiring remixing in the field. Also if the quality of the saltpeter was low (for instance if it was contaminated with highly hygroscopic calcium nitrate), or if the powder was simply old (due to the mildly hygroscopic nature of potassium nitrate), in humid weather it would need to be re-dried. The dust from "repairing" powder in the field was a major hazard. -Loading cannons or bombards before the powder-making advances of the Renaissance was a skilled art. Fine powder loaded haphazardly or too tightly would burn incompletely or too slowly. Typically, the breech-loading powder chamber in the rear of the piece was filled only about half full, the serpentine powder neither too compressed nor too loose, a wooden bung pounded in to seal the chamber from the barrel when assembled, and the projectile placed on. A carefully determined empty space was necessary for the charge to burn effectively. When the cannon was fired through the touchhole, turbulence from the initial surface combustion caused the rest of the powder to be rapidly exposed to the flame.[96] -The advent of much more powerful and easy to use corned powder changed this procedure, but serpentine was used with older guns into the seventeenth century.[97] -Corning[edit] -For gunpowder to explode effectively, the combustible ingredients must be reduced to the smallest possible particle sizes, and thoroughly mixed as possible. Once mixed, however, for better results in a gun, makers discovered that the final product should be in the form of individual, dense, grains that spread the fire quickly from grain to grain, much as straw or twigs catch fire more quickly than a pile of sawdust. -Primarily for safety reasons, size reduction and mixing is done while the ingredients are damp, usually with water. After 1800, instead of forming grains by hand or with sieves, the damp mill-cake was pressed in molds to increase its density and extract the liquid, forming press-cake. The pressing took varying amounts of time, depending on conditions such as atmospheric humidity. The hard, dense product was broken again into tiny pieces, which were separated with sieves to produce a uniform product for each purpose: coarse powders for cannons, finer grained powders for muskets, and the finest for small hand guns and priming.[97] Inappropriately fine-grained powder often caused cannons to burst before the projectile could move down the barrel, due to the high initial spike in pressure.[98] Mammoth powder with large grains made for Rodman's 15-inch cannon reduced the pressure to only 20 percent as high as ordinary cannon powder would have produced.[99] -In the mid-nineteenth century, measurements were made determining that the burning rate within a grain of black powder (or a tightly packed mass) is about 0.20 fps, while the rate of ignition propagation from grain to grain is around 30 fps, over two orders of magnitude faster.[97] -Modern types[edit] -Modern corning first compresses the fine black powder meal into blocks with a fixed density (1.7 g/cm³).[100] In the United States, gunpowder grains were designated F (for fine) or C (for coarse). Grain diameter decreased with a larger number of Fs and increased with a larger number of Cs, ranging from about 2 mm for 7F to 15 mm for 7C. Even larger grains were produced for artillery bore diameters greater than about 17 cm (6.7 in). The standard DuPont Mammoth powder developed by Thomas Rodman and Lammot du Pont for use during the American Civil War had grains averaging 0.6 inches diameter, with edges rounded in a glazing barrel.[99] Other versions had grains the size of golf and tennis balls for use in 20-inch (50-cm) Rodman guns.[101] In 1875 DuPont introduced Hexagonal powder for large artillery, which was pressed using shaped plates with a small center core—about 1.5 inches diameter, like a wagon wheel nut, the center hole widened as the grain burned.[102] By 1882 German makers also produced hexagonal grained powders of a similar size for artillery.[102] -By the late 19th century manufacturing focused on standard grades of black powder from Fg used in large bore rifles and shotguns, through FFg (medium and small-bore arms such as muskets and fusils), FFFg (small-bore rifles and pistols), and FFFFg (extreme small bore, short pistols and most commonly for priming flintlocks).[103] A coarser grade for use in military artillery blanks was designated A-1. These grades were sorted on a system of screens with oversize retained on a mesh of 6 wires per inch, A-1 retained on 10 wires per inch, Fg retained on 14, FFg on 24, FFFg on 46, and FFFFg on 60. Fines designated FFFFFg were usually reprocessed to minimize explosive dust hazards.[104] In the United Kingdom, the main service gunpowders were classified RFG (rifle grained fine) with diameter of one or two millimeters and RLG (rifle grained large) for grain diameters between two and six millimeters.[101] Gunpowder grains can alternatively be categorized by mesh size: the BSS sieve mesh size, being the smallest mesh size, which retains no grains. Recognized grain sizes are Gunpowder G 7, G 20, G 40, and G 90. -Owing to the large market of antique and replica black-powder firearms in the US, modern gunpowder substitutes like Pyrodex, Triple Seven and Black Mag3[105] pellets have been developed since the 1970s. These products, which should not be confused with smokeless powders, aim to produce less fouling (solid residue), while maintaining the traditional volumetric measurement system for charges. Claims of less corrosiveness of these products have been controversial however. New cleaning products for black-powder guns have also been developed for this market.[103] -Other types of gunpowder[edit] -Besides black powder, there are other historically important types of gunpowder. "Brown gunpowder" is cited as composed of 79% nitre, 3% sulfur, and 18% charcoal per 100 of dry powder, with about 2% moisture. Prismatic Brown Powder is a large-grained product the Rottweil Company introduced in 1884 in Germany, which was adopted by the British Royal Navy shortly thereafter. The French navy adopted a fine, 3.1 millimeter, not prismatic grained product called Slow Burning Cocoa (SBC) or "cocoa powder". These brown powders reduced burning rate even further by using as little as 2 percent sulfur and using charcoal made from rye straw that had not been completely charred, hence the brown color.[102] -Lesmok powder was a product developed by DuPont in 1911[106] one of several semi-smokeless products in the industry containing a mixture of black and nitrocellulose powder. It was sold to Winchester and others primarily for .22 and .32 small calibers. Its advantage was that it was believed at the time to be less corrosive than smokeless powders then in use. It was not understood in the U.S. until the 1920s that the actual source of corrosion was the potassium chloride residue from potassium chlorate sensitized primers. The bulkier black powder fouling better disperses primer residue. Failure to mitigate primer corrosion by dispersion caused the false impression that nitrocellulose-based powder caused corrosion.[107] Lesmok had some of the bulk of black powder for dispersing primer residue, but somewhat less total bulk than straight black powder, thus requiring less frequent bore cleaning.[108] It was last sold by Winchester in 1947. -Sulfur-free gunpowder[edit] - -Burst barrel of a muzzle loader pistol replica, which was loaded with nitrocellulose powder instead of black powder and couldn't withstand the higher pressures of the modern propellant -The development of smokeless powders, such as cordite, in the late 19th century created the need for a spark-sensitive priming charge, such as gunpowder. However, the sulfur content of traditional gunpowders caused corrosion problems with Cordite Mk I and this led to the introduction of a range of sulfur-free gunpowders, of varying grain sizes.[64] They typically contain 70.5 parts of saltpeter and 29.5 parts of charcoal.[64] Like black powder, they were produced in different grain sizes. In the United Kingdom, the finest grain was known as sulfur-free mealed powder (SMP). Coarser grains were numbered as sulfur-free gunpowder (SFG n): 'SFG 12', 'SFG 20', 'SFG 40' and 'SFG 90', for example; where the number represents the smallest BSS sieve mesh size, which retained no grains. -Sulfur's main role in gunpowder is to decrease the ignition temperature. A sample reaction for sulfur-free gunpowder would be -6 KNO3 + C7H4O → 3 K2CO3 + 4 CO2 + 2 H2O + 3 N2 -Combustion characteristics[edit] -A simple, commonly cited, chemical equation for the combustion of black powder is -2 KNO3 + S + 3 C → K2S + N2 + 3 CO2. -A balanced, but still simplified, equation is[109] -10 KNO3 + 3 S + 8 C → 2 K2CO3 + 3 K2SO4 + 6 CO2 + 5 N2. -Although charcoal's chemical formula varies, it can be best summed up by its empirical formula: C7H4O. -Therefore, an even more accurate equation of the decomposition of regular black powder with the use of sulfur can be described as: -6 KNO3 + C7H4O + 2 S → K2CO3 + K2SO4 + K2S + 4 CO2 + 2 CO + 2 H2O + 3 N2 -Black powder without the use of sulfur: -10 KNO3 + 2 C7H4O → 5 K2CO3 + 4 CO2 + 5 CO + 4 H2O + 5 N2 -The burning of gunpowder does not take place as a single reaction, however, and the byproducts are not easily predicted. One study's results showed that it produced (in order of descending quantities) 55.91% solid products: potassium carbonate, potassium sulfate, potassium sulfide, sulfur, potassium nitrate, potassium thiocyanate, carbon, ammonium carbonate and 42.98% gaseous products: carbon dioxide, nitrogen, carbon monoxide, hydrogen sulfide, hydrogen, methane, 1.11% water. -Black powder made with less-expensive and more plentiful sodium nitrate (in appropriate proportions) works just as well but is more hygroscopic than powders made from Potassium nitrate—popularly known as saltpeter. Because corned black powder grains made with saltpeter are less affected by moisture in the air, they can be stored unsealed without degradation by humidity. Muzzleloaders have been known to fire after hanging on a wall for decades in a loaded state, provided they remained dry. By contrast, black powder made with sodium nitrate must be kept sealed to remain stable. -Gunpowder contains 3 megajoules per kilogram, and contains its own oxidant. For comparison, the energy density of TNT is 4.7 megajoules per kilogram, and the energy density of gasoline is 47.2 megajoules per kilogram. Gunpowder is a low explosive and as such it does not detonate; rather it deflagrates. Since it contains its own oxidizer and additionally burns faster under pressure, its combustion is capable of rupturing containers such as shell, grenade, or improvised "pipe bomb" or "pressure cooker" casings, forming shrapnel. -Advantages[edit] -In quarrying, high explosives are generally preferred for shattering rock. However, because of its low brisance, black powder causes fewer fractures and results in more usable stone compared to other explosives, making black powder useful for blasting monumental stone such as granite and marble. Black powder is well suited for blank rounds, signal flares, burst charges, and rescue-line launches. Black powder is also used in fireworks for lifting shells, in rockets as fuel, and in certain special effects. -Disadvantages[edit] -Black powder has a low energy density compared to modern "smokeless" powders, and thus to achieve high energy loadings, large amounts of black powder are needed with heavy projectiles. Black powder also produces thick smoke as a byproduct, which in military applications may give a soldier's location away to an enemy observer and may also impair aiming for additional shots. -Combustion converts less than half the mass of black powder to gas. The rest ends up as a thick layer of soot inside the barrel. In addition to being a nuisance, the residue from burnt black powder is hygroscopic and with the addition of moisture absorbed from the air, this residue forms a caustic substance. The soot contains potassium oxide or sodium oxide that turns into potassium hydroxide, or sodium hydroxide, which corrodes wrought iron or steel gun barrels. Black powder arms must be well cleaned both inside and out to remove the residue. The matchlock musket or pistol (an early gun ignition system), as well as the flintlock would often be unusable in wet weather, due to powder in the pan being exposed and dampened. Because of this unreliability, soldiers carrying muskets, known as musketeers, were armed with additional weapons such as swords or pikes. The bayonet was developed to allow the musket to be used as a pike, thus eliminating the need for the soldier to carry a secondary weapon. -Transportation[edit] -The United Nations Model Regulations on the Transportation of Dangerous Goods and national transportation authorities, such as United States Department of Transportation, have classified gunpowder (black powder) as a Group A: Primary explosive substance for shipment because it ignites so easily. Complete manufactured devices containing black powder are usually classified as Group D: Secondary detonating substance, or black powder, or article containing secondary detonating substance, such as firework, class D model rocket engine, etc., for shipment because they are harder to ignite than loose powder. As explosives, they all fall into the category of Class 1. -Other uses[edit] -Besides its use as an explosive, gunpowder has been occasionally employed for other purposes; after the Battle of Aspern-Essling (1809), the surgeon of the Napoleonic Army Larrey combated the lack of food for the wounded under his care by preparing a bouillon of horse meat seasoned with gunpowder for lack of salt.[110][111] It was also used for sterilizing on ships when there was no alcohol. -Jack Tars (British sailors) used gunpowder to create tattoos when ink wasn't available, by pricking the skin and rubbing the powder into the wound in a method known as traumatic tattooing.[112] -Christiaan Huygens experimented with gunpowder in 1673 in an early attempt to build an internal combustion engine, but he did not succeed. Modern attempts to recreate his invention were similarly unsuccessful. -Fireworks use gunpowder as lifting and burst charges, although sometimes other more powerful compositions are added to the burst charge to improve performance in small shells or provide a louder report. Most modern firecrackers no longer contain black powder. -Beginning in the 1930s, gunpowder or smokeless powder was used in rivet guns, stun guns for animals, cable splicers and other industrial construction tools.[113] The "stud gun" drove nails or screws into solid concrete, a function not possible with hydraulic tools. See Powder-actuated tool. Shotguns have been used to eliminate persistent material rings in operating rotary kilns (such as those for cement, lime, phosphate, etc.) and clinker in operating furnaces, and commercial tools make the method more reliable.[114] -Near London in 1853, Captain Shrapnel demonstrated a method for crushing gold-bearing ores by firing them from a cannon into an iron chamber, and "much satisfaction was expressed by all present". He hoped it would be useful on the goldfields of California and Australia. Nothing came of the invention, as continuously-operating crushing machines that achieved more reliable comminution were already coming into use.[115] -See also[edit] -Ballistics -Black powder substitute -Faversham explosives industry -Bulk loaded liquid propellants -Gunpowder magazine -Gunpowder Plot -Berthold Schwarz -Gunpowder warfare -History of gunpowder -Technology of the Song Dynasty -References[edit] -Jump up ^ http://www.merriam-webster.com/dictionary/gunpowder -Jump up ^ Jai Prakash Agrawal (2010).

Around that same year, a Syrian named Hasan al-Rammah wrote a book that, as he put it, "treats of machines of fire to be used for amusement or for useful purposes." He talked of rockets, fireworks, fire lances, and other incendiaries, using terms that suggested he derived his knowledge from Chinese sources.

The term is unique to the United States and is generally not used in other English-speaking countries, which initially used proprietary names such as "Ballistite" and "Cordite" but gradually shifted to "propellant" as the generic term. -The basis of the term smokeless is that the combustion products are mainly gaseous, compared to around 55% solid products (mostly potassium carbonate, potassium sulfate, and potassium sulfide) for black powder.[1] Despite its name, smokeless powder is not completely smoke-free;[2] while there may be little noticeable smoke from small-arms ammunition, smoke from artillery fire can be substantial. This article focuses on nitrocellulose formulations, but the term smokeless powder was also used to describe various picrate mixtures with nitrate, chlorate, or dichromate oxidizers during the late 19th century, before the advantages of nitrocellulose became evident.[3] -Since the 14th century[4] gunpowder was not actually a physical "powder," and smokeless powder can only be produced as a pelletized or extruded granular material. Smokeless powder allowed the development of modern semi- and fully automatic firearms and lighter breeches and barrels for artillery. Burnt black powder leaves a thick, heavy fouling that is hygroscopic and causes rusting of the barrel. The fouling left by smokeless powder exhibits none of these properties (though some primer compounds can leave hygroscopic salts that have a similar effect; non-corrosive primer compounds were introduced in the 1920s[5][6]). This makes an autoloading firearm with many moving parts feasible (which would otherwise jam or seize under heavy black powder fouling). -Smokeless powders are classified as, typically, division 1.3 explosives under the UN Recommendations on the transportation of Dangerous goods – Model Regulations, regional regulations (such as ADR) and national regulations (such the United States' ATF). However, they are used as solid propellants; in normal use, they undergo deflagration rather than detonation. -Contents [hide] -1 Background -2 Nitroglycerine and guncotton -3 Propellant improvements -4 Chemical formulations -5 Instability and stabilization -6 Physical variations -7 Smokeless propellant components -8 Manufacturing -9 Flashless propellant -10 See also -11 References -11.1 Notes -11.2 Sources -12 External links -Background[edit] -Military commanders had been complaining since the Napoleonic Wars about the problems of giving orders on a battlefield obscured by the smoke of firing. Verbal commands could not be heard above the noise of the guns, and visual signals could not be seen through the thick smoke from the gunpowder used by the guns. Unless there was a strong wind, after a few shots, soldiers using black powder ammunition would have their view obscured by a huge cloud of smoke. Snipers or other concealed shooters were given away by a cloud of smoke over the firing position. Black powder is also corrosive, making cleaning mandatory after every use. Likewise, black powder's tendency to produce severe fouling caused actions to jam and often made reloading difficult. -Nitroglycerine and guncotton[edit] -Nitroglycerine was synthesized by the Italian chemist Ascanio Sobrero in 1847.[7] It was subsequently developed and manufactured by Alfred Nobel as an industrial explosive, but even then it was unsuitable as a propellant: despite its energetic and smokeless qualities, it detonates instead of deflagrating smoothly, making it more amenable to shattering a gun than propelling a projectile out of it. Nitroglycerine per se is also highly unstable, making it unfit to be carried in battlefield conditions. -A major step forward was the discovery of guncotton, a nitrocellulose-based material, by Swiss chemist Christian Friedrich Schönbein in 1846. He promoted its use as a blasting explosive[8] and sold manufacturing rights to the Austrian Empire. Guncotton was more powerful than gunpowder, but at the same time was once again somewhat more unstable. John Taylor obtained an English patent for guncotton; and John Hall & Sons began manufacture in Faversham. -English interest languished after an explosion destroyed the Faversham factory in 1847. Austrian Baron Wilhelm Lenk von Wolfsberg built two guncotton plants producing artillery propellent, but it too was dangerous under field conditions, and guns that could fire thousands of rounds using gunpowder would reach their service life after only a few hundred shots with the more powerful guncotton. Small arms could not withstand the pressures generated by guncotton at all. -After one of the Austrian factories blew up in 1862, Thomas Prentice & Company began manufacturing guncotton in Stowmarket in 1863; and British War Office chemist Sir Frederick Abel began thorough research at Waltham Abbey Royal Gunpowder Mills leading to a manufacturing process that eliminated the impurities in nitrocellulose making it safer to produce and a stable product safer to handle. Abel patented this process in 1865, when the second Austrian guncotton factory exploded. After the Stowmarket factory exploded in 1871, Waltham Abbey began production of guncotton for torpedo and mine warheads.[9] -Propellant improvements[edit] -In 1863, Prussian artillery captain Johann F. E. Schultze patented a small arms propellent of nitrated hardwood impregnated with saltpetre or barium nitrate. Prentice received an 1866 patent for a sporting powder of nitrated paper manufactured at Stowmarket, but ballistic uniformity suffered as the paper absorbed atmospheric moisture. In 1871, Frederick Volkmann received an Austrian patent for a colloided version of Schultze powder called Collodin, which he manufactured near Vienna for use in sporting firearms. Austrian patents were not published at the time, and the Austrian Empire considered the operation a violation of the government monopoly on explosives manufacture and closed the Volkmann factory in 1875.[9] In 1882, the Explosives Company at Stowmarket patented an improved formulation of nitrated cotton gelatinised by ether-alcohol with nitrates of potassium and barium. These propellants were suitable for shotguns but not rifles.[10] - -Poudre B single-base smokeless powder flakes -In 1884, Paul Vieille invented a smokeless powder called Poudre B (short for poudre blanche—white powder, as distinguished from black powder)[11] made from 68.2% insoluble nitrocellulose, 29.8% soluble nitrocellusose gelatinized with ether and 2% paraffin. This was adopted for the Lebel rifle.[12] It was passed through rollers to form paper thin sheets, which were cut into flakes of the desired size.[11] The resulting propellant, today known as pyrocellulose, contains somewhat less nitrogen than guncotton and is less volatile. A particularly good feature of the propellant is that it will not detonate unless it is compressed, making it very safe to handle under normal conditions. -Vieille's powder revolutionized the effectiveness of small guns, because it gave off almost no smoke and was three times more powerful than black powder. Higher muzzle velocity meant a flatter trajectory and less wind drift and bullet drop, making 1000 meter shots practicable. Since less powder was needed to propel a bullet, the cartridge could be made smaller and lighter. This allowed troops to carry more ammunition for the same weight. Also, it would burn even when wet. Black powder ammunition had to be kept dry and was almost always stored and transported in watertight cartridges. -Other European countries swiftly followed and started using their own versions of Poudre B, the first being Germany and Austria, which introduced new weapons in 1888. Subsequently Poudre B was modified several times with various compounds being added and removed. Krupp began adding diphenylamine as a stabilizer in 1888.[9] -Meanwhile, in 1887, Alfred Nobel obtained an English patent for a smokeless gunpowder he called Ballistite. In this propellant the fibrous structure of cotton (nitro-cellulose) was destroyed by a nitro-glycerine solution instead of a solvent.[13] In England in 1889, a similar powder was patented by Hiram Maxim, and in the USA in 1890 by Hudson Maxim.[14] Ballistite was patented in the United States in 1891. -The Germans adopted ballistite for naval use in 1898, calling it WPC/98. The Italians adopted it as filite, in cord instead of flake form, but realising its drawbacks changed to a formulation with nitroglycerine they called solenite. In 1891 the Russians tasked the chemist Mendeleef with finding a suitable propellant, he created nitrocellulose gelatinised by ether-alcohol, which produced more nitrogen and more uniform colloidal structure than the French use of nitro-cottons in Poudre B. He called it pyro-collodion.[13] -Britain conducted trials on all the various types of propellant brought to their attention, but were dissatisfied with them all and sought something superior to all existing types. In 1889, Sir Frederick Abel, James Dewar and Dr W Kellner patented (Nos 5614 and 11,664 in the names of Abel and Dewar) a new formulation that was manufactured at the Royal Gunpowder Factory at Waltham Abbey. It entered British service in 1891 as Cordite Mark 1. Its main composition was 58% Nitro-glycerine, 37% Guncotton and 3% mineral jelly. A modified version, Cordite MD, entered service in 1901, this increased guncotton to 65% and reduced nitro-glycerine to 30%, this change reduced the combustion temperature and hence erosion and barrel wear. Cordite's advantages over gunpowder were reduced maximum pressure in the chamber (hence lighter breeches, etc.) but longer high pressure. Cordite could be made in any desired shape or size.[15] The creation of cordite led to a lengthy court battle between Nobel, Maxim, and another inventor over alleged British patent infringement. -The Anglo-American Explosives Company began manufacturing its shotgun powder in Oakland, New Jersey in 1890. DuPont began producing guncotton at Carneys Point Township, New Jersey in 1891.[3] Charles E. Munroe of the Naval Torpedo Station in Newport, Rhode Island patented a formulation of guncotton colloided with nitrobenzene, called Indurite, in 1891.[16] Several United States firms began producing smokeless powder when Winchester Repeating Arms Company started loading sporting cartridges with Explosives Company powder in 1893. California Powder Works began producing a mixture of nitroglycerine and nitrocellulose with ammonium picrate as Peyton Powder, Leonard Smokeless Powder Company began producing nitroglycerine-nitrocellulose Ruby powders, Laflin & Rand negotiated a license to produce Ballistite, and DuPont started producing smokeless shotgun powder. The United States Army evaluated 25 varieties of smokeless powder and selected Ruby and Peyton Powders as the most suitable for use in the Krag-Jørgensen service rifle. Ruby was preferred, because tin-plating was required to protect brass cartridge cases from picric acid in the Peyton Powder. Rather than paying the required royalties for Ballistite, Laflin & Rand financed Leonard's reorganization as the American Smokeless Powder Company. United States Army Lieutenant Whistler assisted American Smokeless Powder Company factory superintendent Aspinwall in formulating an improved powder named W.A. for their efforts. W.A. smokeless powder was the standard for United States military service rifles from 1897 until 1908.[3] -In 1897, United States Navy Lieutenant John Bernadou patented a nitrocellulose powder colloided with ether-alcohol.[16] The Navy licensed or sold patents for this formulation to DuPont and the California Powder Works while retaining manufacturing rights for the Naval Powder Factory, Indian Head, Maryland constructed in 1900. The United States Army adopted the Navy single-base formulation in 1908 and began manufacture at Picatinny Arsenal.[3] By that time Laflin & Rand had taken over the American Powder Company to protect their investment, and Laflin & Rand had been purchased by DuPont in 1902.[17] Upon securing a 99-year lease of the Explosives Company in 1903, DuPont enjoyed use of all significant smokeless powder patents in the United States, and was able to optimize production of smokeless powder.[3] When government anti-trust action forced divestiture in 1912, DuPont retained the nitrocellulose smokeless powder formulations used by the United States military and released the double-base formulations used in sporting ammunition to the reorganized Hercules Powder Company. These newer propellants were more stable and thus safer to handle than Poudre B, and also more powerful. -Chemical formulations[edit] -"Double base" redirects here. For the musical instrument, see double bass. -Currently, propellants using nitrocellulose (detonation velocity 7,300 m/s (23,950 ft/s)) (typically an ether-alcohol colloid of nitrocellulose) as the sole explosive propellant ingredient are described as single-base powder.[18] -Propellants mixtures containing nitrocellulose and nitroglycerin (detonation velocity 7,700 m/s (25,260 ft/s)) as explosive propellant ingredients are known as double-base powder.[19] -During the 1930s triple-base propellant containing nitrocellulose, nitroglycerin, and a substantial quantity of nitroguanidine (detonation velocity 8,200 m/s (26,900 ft/s)) as explosive propellant ingredients was developed. These propellant mixtures have reduced flash and flame temperature without sacrificing chamber pressure compared to single and double base propellants, albeit at the cost of more smoke. -In practice, triple base propellants are reserved mainly for large caliber ammunition such as used in (naval) artillery and tank guns. During World War II it had some use by British artillery. After that war it became the standard propellant in all British large caliber ammunition designs except small-arms. Most western nations, except the United States, followed a similar path. -In the late 20th century new propellant formulations started to appear. These are based on nitroguanidine and high explosives of the RDX (detonation velocity 8,750 m/s (28,710 ft/s)) type. -Instability and stabilization[edit] -Nitrocellulose deteriorates with time, yielding acidic byproducts. Those byproducts catalyze the further deterioration, increasing its rate. The released heat, in case of bulk storage of the powder, or too large blocks of solid propellant, can cause self-ignition of the material. Single-base nitrocellulose propellants are hygroscopic and most susceptible to degradation; double-base and triple-base propellants tend to deteriorate more slowly. To neutralize the decomposition products, which could otherwise cause corrosion of metals of the cartridges and gun barrels, calcium carbonate is added to some formulations. -To prevent buildup of the deterioration products, stabilizers are added. Diphenylamine is one of the most common stabilizers used. Nitrated analogs of diphenylamine formed in the process of stabilizing decomposing powder are sometimes used as stabilizers themselves.[20][21] The stabilizers are added in the amount of 0.5–2% of the total amount of the formulation; higher amounts tend to degrade its ballistic properties. The amount of the stabilizer is depleted with time. Propellants in storage should be periodically tested for the amount of stabilizer remaining, as its depletion may lead to auto-ignition of the propellant. -Physical variations[edit] - -Ammunition handloading powders -Smokeless powder may be corned into small spherical balls or extruded into cylinders or strips with many cross-sectional shapes (strips with various rectangular proportions, single or multi-hole cylinders, slotted cylinders) using solvents such as ether. These extrusions can be cut into short ('flakes') or long pieces ('cords' many inches long). Cannon powder has the largest pieces. -The properties of the propellant are greatly influenced by the size and shape of its pieces. The specific surface area of the propellant influences the speed of burning, and the size and shape of the particles determine the specific surface area. By manipulation of the shape it is possible to influence the burning rate and hence the rate at which pressure builds during combustion. Smokeless powder burns only on the surfaces of the pieces. Larger pieces burn more slowly, and the burn rate is further controlled by flame-deterrent coatings that retard burning slightly. The intent is to regulate the burn rate so that a more or less constant pressure is exerted on the propelled projectile as long as it is in the barrel so as to obtain the highest velocity. The perforations stabilize the burn rate because as the outside burns inward (thus shrinking the burning surface area) the inside is burning outward (thus increasing the burning surface area, but faster, so as to fill up the increasing volume of barrel presented by the departing projectile).[22] Fast-burning pistol powders are made by extruding shapes with more area such as flakes or by flattening the spherical granules. Drying is usually performed under a vacuum. The solvents are condensed and recycled. The granules are also coated with graphite to prevent static electricity sparks from causing undesired ignitions.[23] -Faster-burning propellants generate higher temperatures and higher pressures, however they also increase wear on gun barrels. -Smokeless propellant components[edit] -The propellant formulations may contain various energetic and auxiliary components: -Propellants: -Nitrocellulose, an energetic component of most smokeless propellants[24] -Nitroglycerin, an energetic component of double-base and triple-base formulations[24] -Nitroguanidine, a component of triple-base formulations[24] -D1NA (bis-nitroxyethylnitramine)[25] -Fivonite (tetramethylolcyclopentanone)[25] -DGN (di-ethylene glycol dinitrate)[26] -Acetyl cellulose[27] -Deterrents, (or moderants), to slow the burning rate -Centralites (symmetrical diphenyl urea—primarily diethyl or dimethyl)[28][29] -Dibutyl phthalate[24][29] -Dinitrotoluene (toxic, carcinogenic, and obsolete)[24][30] -Akardite (asymmetrical diphenyl urea)[26] -ortho-tolyl urethane[31] -Polyester adipate -Camphor (obsolete)[29] -Stabilizers, to prevent or slow down self-decomposition[32] -Diphenylamine[33] -Petroleum jelly[34] -Calcium carbonate[24] -Magnesium oxide[26] -Sodium bicarbonate[27] -beta-naphthol methyl ether[31] -Amyl alcohol (obsolete)[35] -Aniline (obsolete)[36] -Decoppering additives, to hinder the buildup of copper residues from the gun barrel rifling -Tin metal and compounds (e.g., tin dioxide)[24][37] -Bismuth metal and compounds (e.g., bismuth trioxide, bismuth subcarbonate, bismuth nitrate, bismuth antimonide); the bismuth compounds are favored as copper dissolves in molten bismuth, forming brittle and easily removable alloy -Lead foil and lead compounds, phased out due to toxicity[25] -Flash reducers, to reduce the brightness of the muzzle flash (all have a disadvantage: the production of smoke)[38] -Potassium chloride[39] -Potassium nitrate -Potassium sulfate[24][37] -Potassium hydrogen tartarate (a byproduct of wine production formerly used by French artillery)[39] -Wear reduction additives, to lower the wear of the gun barrel liners[40] -Wax -Talc -Titanium dioxide -Polyurethane jackets over the powder bags, in large guns -Other additives -Ethyl acetate, a solvent for manufacture of spherical powder[34] -Rosin, a surfactant to hold the grain shape of spherical powder -Graphite, a lubricant to cover the grains and prevent them from sticking together, and to dissipate static electricity[23] -Manufacturing[edit] -This section describes procedures used in the United States. See Cordite for alternative procedures formerly used in the United Kingdom. -The United States Navy manufactured single-base tubular powder for naval artillery at Indian Head, Maryland, beginning in 1900. Similar procedures were used for United States Army production at Picatinny Arsenal beginning in 1907[18] and for manufacture of smaller grained Improved Military Rifle (IMR) powders after 1914. Short-fiber cotton linter was boiled in a solution of sodium hydroxide to remove vegetable waxes, and then dried before conversion to nitrocellulose by mixing with concentrated nitric and sulfuric acids. Nitrocellulose still resembles fibrous cotton at this point in the manufacturing process, and was typically identified as pyrocellulose because it would spontaneously ignite in air until unreacted acid was removed. The term guncotton was also used; although some references identify guncotton as a more extensively nitrated and refined product used in torpedo and mine warheads prior to use of TNT.[41] -Unreacted acid was removed from pyrocellulose pulp by a multistage draining and water washing process similar to that used in paper mills during production of chemical woodpulp. Pressurized alcohol removed remaining water from drained pyrocellulose prior to mixing with ether and diphenylamine. The mixture was then fed through a press extruding a long turbular cord form to be cut into grains of the desired length.[42] -Alcohol and ether were then evaporated from "green" powder grains to a remaining solvent concentration between 3 percent for rifle powders and 7 percent for large artillery powder grains. Burning rate is inversely proportional to solvent concentration. Grains were coated with electrically conductive graphite to minimize generation of static electricity during subsequent blending. "Lots" containing more than ten tonnes of powder grains were mixed through a tower arrangement of blending hoppers to minimize ballistic differences. Each blended lot was then subjected to testing to determine the correct loading charge for the desired performance.[43][44] -Military quantities of old smokeless powder were sometimes reworked into new lots of propellants.[45] Through the 1920s Dr. Fred Olsen worked at Picatinny Arsenal experimenting with ways to salvage tons of single-base cannon powder manufactured for World War I. Dr. Olsen was employed by Western Cartridge Company in 1929 and developed a process for manufacturing spherical smokeless powder by 1933.[46] Reworked powder or washed pyrocellulose can be dissolved in ethyl acetate containing small quantities of desired stabilizers and other additives. The resultant syrup, combined with water and surfactants, can be heated and agitated in a pressurized container until the syrup forms an emulsion of small spherical globules of the desired size. Ethyl acetate distills off as pressure is slowly reduced to leave small spheres of nitrocellulose and additives. The spheres can be subsequently modified by adding nitroglycerine to increase energy, flattening between rollers to a uniform minimum dimension, coating with phthalate deterrents to retard ignition, and/or glazing with graphite to improve flow characteristics during blending.[47][48] -Modern smokeless powder is produced in the United States by St. Marks Powder, Inc. owned by General Dynamics.[49] -Flashless propellant[edit] -Muzzle flash is the light emitted in the vicinity of the muzzle by the hot propellant gases and the chemical reactions that follow as the gases mix with the surrounding air. Before projectiles exit a slight pre-flash may occur from gases leaking past the projectiles. Following muzzle exit the heat of gases is usually sufficient to emit visible radiation – the primary flash. The gases expand but as they pass through the Mach disc they are re-compressed to produce an intermediate flash. Hot combustible gases (e.g. hydrogen and carbon-monoxide) may follow when they mix with oxygen in the surrounding air to produce the secondary flash, the brightest. The secondary flash does not usually occur with small-arms.[50] -Nitrocellulose contains insufficient oxygen to completely oxidize its carbon and hydrogen. The oxygen deficit is increased by addition of graphite and organic stabilizers. Products of combustion within the gun barrel include flammable gasses like hydrogen and carbon monoxide. At high temperature, these flammable gasses will ignite when turbulently mixed with atmospheric oxygen beyond the muzzle of the gun. During night engagements the flash produced by ignition can reveal the location of the gun to enemy forces[51] and cause temporary night-blindness among the gun crew by photo-bleaching visual purple.[52] -Flash suppressors are commonly used on small arms to reduce the flash signature, but this approach is not practical for artillery. Artillery muzzle flash up to 150 feet (46 m) from the muzzle has been observed, and can be reflected off clouds and be visible for distances up to 30 miles (48 km).[51] For artillery the most effective method is a propellant that produces a large proportion of inert nitrogen at relatively low temperatures that dilutes the combustible gases. Triple based propellants are used for this because of the nitrogen in the nitroguandine.[53] -Before the use of triple based propellants the usual method of flash reduction was to add inorganic salts like potassium chloride so their specific heat capacity might reduce the temperature of combustion gasses and their finely divided particulate smoke might block visible wavelengths of radiant energy of combustion.[39] -See also[edit] -Portal icon Pyrotechnics portal -Antique guns -Ballistite -Cordite -Firearms -Gunpowder -Nitrocellulose -Small arms -Brown-brown – a drug created by mixing cocaine with cartridge powder -References[edit] -Notes[edit] -Jump up ^ Hatcher, Julian S. and Barr, Al Handloading Hennage Lithograph Company (1951) p.34 -Jump up ^ Fairfield, A.

Most "fire" found in daily life, from flames to explosions, is deflagration. Deflagration is different from detonation, which is supersonic and propagates through shock. -Contents [hide] -1 Applications -2 Oil/wax fire and water -3 Flame physics -4 Damaging deflagration events -5 See also -6 References -Applications[edit] -In engineering applications, deflagrations are easier to control than detonations. Consequently, they are better suited when the goal is to move an object (a bullet in a gun, or a piston in an internal combustion engine) with the force of the expanding gas. Typical examples of deflagrations are the combustion of a gas-air mixture in a gas stove or a fuel-air mixture in an internal combustion engine, and the rapid burning of gunpowder in a firearm or of pyrotechnic mixtures in fireworks. Deflagration systems and products can also be used in mining, demolition and stone quarrying via gas pressure blasting as a beneficial alternative to high explosives. -Oil/wax fire and water[edit] -Adding water to a burning hydrocarbon such as oil or wax produces a deflagration. The water boils rapidly and ejects the burning material as a fine spray of droplets. A deflagration then occurs as the fine mist of oil ignites and burns extremely rapidly. These are particularly common in chip pan fires, which are responsible for one in five household fires in Britain.[2] -Flame physics[edit] -The underlying flame physics can be understood with the help of an idealized model consisting of a uniform one-dimensional tube of unburnt and burned gaseous fuel, separated by a thin transitional region of width \delta\; in which the burning occurs. The burning region is commonly referred to as the flame or flame front. In equilibrium, thermal diffusion across the flame front is balanced by the heat supplied by burning. -There are two characteristic timescales which are important here. The first is the thermal diffusion timescale \tau_d\;, which is approximately equal to -\tau_d \simeq \delta^2 / \kappa, -where \kappa \; is the thermal diffusivity. The second is the burning timescale \tau_b that strongly decreases with temperature, typically as -\tau_b\propto \exp[\Delta U/(k_B T_f)], -where \Delta U\; is the activation barrier for the burning reaction and T_f\; is the temperature developed as the result of burning; the value of this so-called "flame temperature" can be determined from the laws of thermodynamics. -For a stationary moving deflagration front, these two timescales must be equal: the heat generated by burning is equal to the heat carried away by heat transfer. This makes it possible to calculate the characteristic width \delta\; of the flame front: -\tau_b = \tau_d\;, -thus - \delta \simeq \sqrt {\kappa \tau_b} . -Now, the thermal flame front propagates at a characteristic speed S_l\;, which is simply equal to the flame width divided by the burn time: -S_l \simeq \delta / \tau_b \simeq \sqrt {\kappa / \tau_b} . -This simplified model neglects the change of temperature and thus the burning rate across the deflagration front. This model also neglects the possible influence of turbulence. As a result, this derivation gives only the laminar flame speed -- hence the designation S_l\;. -Damaging deflagration events[edit] -Damage to buildings, equipment and people can result from a large-scale, short-duration deflagration. The potential damage is primarily a function of the total amount of fuel burned in the event (total energy available), the maximum flame velocity that is achieved, and the manner in which the expansion of the combustion gases is contained. -In free-air deflagrations, there is a continuous variation in deflagration effects relative to the maximum flame velocity. When flame velocities are low, the effect of a deflagration is to release heat. Some authors use the term flash fire to describe these low-speed deflagrations. At flame velocities near the speed of sound, the energy released is in the form of pressure and the results resemble a detonation. Between these extremes both heat and pressure are released. -When a low-speed deflagration occurs within a closed vessel or structure, pressure effects can produce damage due to expansion of gases as a secondary effect. The heat released by the deflagration causes the combustion gases and excess air to expand thermally. The net result is that the volume of the vessel or structure must expand to accommodate the hot combustion gases, or the vessel must be strong enough to withstand the additional internal pressure, or it fails, allowing the gases to escape. The risks of deflagration inside waste storage drums is a growing concern in storage facilities. -See also[edit] - Look up deflagration in Wiktionary, the free dictionary. -Pressure piling -References[edit] -Jump up ^ "Glossary D-H".

Lying off the north-western coast of the European mainland, the country includes the island of Great Britain (a term also applied loosely to refer to the whole country),[8] the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another state: the Republic of Ireland.[nb 4] Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea in the east and the English Channel in the south. The Irish Sea lies between Great Britain and Ireland. The UK has an area of 243,610 square kilometres (94,060 sq mi), making it the 78th-largest sovereign state in the world and the 11th-largest in Europe. -The United Kingdom is the 22nd-most populous country, with an estimated 64.1 million inhabitants.[3] It is a constitutional monarchy with a parliamentary system of governance.[9][10] Its capital city is London, an important global city and financial centre with the fourth-largest urban area in Europe.[11] The current monarch—since 6 February 1952—is Queen Elizabeth II. The UK consists of four countries: England, Scotland, Wales, and Northern Ireland.[12] The latter three have devolved administrations,[13] each with varying powers,[14][15] based in their capitals, Edinburgh, Cardiff, and Belfast, respectively. Guernsey, Jersey, and the Isle of Man are not part of the United Kingdom, being Crown dependencies with the British Government responsible for defence and international representation.[16] The UK has fourteen Overseas Territories,[17] including the disputed Falkland Islands, Gibraltar, and Indian Ocean Territory. -The relationships among the countries of the United Kingdom have changed over time. Wales was annexed by the Kingdom of England under the Acts of Union of 1536 and 1543. A treaty between England and Scotland resulted in a unified Kingdom of Great Britain in 1707, which in 1801, merged with the Kingdom of Ireland to form the United Kingdom of Great Britain and Ireland. In 1922, five-sixths of Ireland seceded from the country, leaving the present formulation of the United Kingdom of Great Britain and Northern Ireland.[nb 5] British Overseas Territories, formerly colonies, are the remnants of the British Empire which, at its height in the late 19th and early 20th centuries, encompassed almost a quarter of the world's land mass and was the largest empire in history. British influence can be observed in the language, culture, and legal systems of many of its former colonies. -The United Kingdom is a developed country and has the world's sixth-largest economy by nominal GDP and tenth-largest by purchasing power parity. The country is considered to have a high-income economy and is categorised as very high in the Human Development Index, currently ranking 14th in the world. It was the world's first industrialised country and the world's foremost power during the 19th and early 20th centuries.[18][19] The UK remains a great power with considerable economic, cultural, military, scientific, and political influence internationally.[20][21] It is a recognised nuclear weapons state and its military expenditure ranks fifth or sixth in the world.[22][23] The UK has been a permanent member of the United Nations Security Council since its first session in 1946. It has been a member state of the European Union (EU) and its predecessor, the European Economic Community (EEC), since 1973; it is also a member of the Commonwealth of Nations, the Council of Europe, the G7, the G8, the G20, NATO, the Organisation for Economic Co-operation and Development (OECD), and the World Trade Organization (WTO). -Contents [hide] -1 Etymology and terminology -2 History -2.1 Before 1707 -2.2 Since the Acts of Union of 1707 -3 Geography -3.1 Climate -3.2 Administrative divisions -4 Dependencies -5 Politics -5.1 Government -5.2 Devolved administrations -5.3 Law and criminal justice -5.4 Foreign relations -5.5 Military -6 Economy -6.1 Science and technology -6.2 Transport -6.3 Energy -7 Demographics -7.1 Ethnic groups -7.2 Languages -7.3 Religion -7.4 Migration -7.5 Education -7.6 Healthcare -8 Culture -8.1 Literature -8.2 Music -8.3 Visual art -8.4 Cinema -8.5 Media -8.6 Philosophy -8.7 Sport -8.8 Symbols -9 See also -10 Notes -11 References -12 Further reading -13 External links -Etymology and terminology -See also: Britain (placename) and Terminology of the British Isles -The 1707 Acts of Union declared that the kingdoms of England and Scotland were "United into One Kingdom by the Name of Great Britain", though the new state is also referred to in the Acts as the "Kingdom of Great Britain", "United Kingdom of Great Britain" and "United Kingdom".[24][25][nb 6] However, the term "united kingdom" is only found in informal use during the 18th century and the country was only occasionally referred to as he "United Kingdom of Great Britain".[26] The Acts of Union 1800 united the Kingdom of Great Britain and the Kingdom of Ireland in 1801, forming the United Kingdom of Great Britain and Ireland. The name "United Kingdom of Great Britain and Northern Ireland" was adopted following the independence of the Irish Free State, and the partition of Ireland, in 1922, which left Northern Ireland as the only part of the island of Ireland within the UK.[27] -Although the United Kingdom, as a sovereign state, is a country, England, Scotland, Wales, and to a lesser degree, Northern Ireland, are also regarded as countries, though they are not sovereign states.[28][29] Scotland, Wales and Northern Ireland have devolved self-government.[30][31] The British Prime Minister's website has used the phrase "countries within a country" to describe the United Kingdom.[12] Some statistical summaries, such as those for the twelve NUTS 1 regions of the UK, also refer to Scotland, Wales and Northern Ireland as "regions".[32][33] Northern Ireland is also referred to as a "province".[28][34] With regard to Northern Ireland, the descriptive name used "can be controversial, with the choice often revealing one's political preferences."[35] -The term Britain is often used as synonym for the United Kingdom. The term Great Britain, by contrast, refers conventionally to the island of Great Britain, or politically to England, Scotland and Wales in combination.[36][37][38] However, it is sometimes used as a loose synonym for the United Kingdom as a whole.[39][40] GB and GBR are the standard country codes for the United Kingdom (see ISO 3166-2 and ISO 3166-1 alpha-3) and are consequently used by international organisations to refer to the United Kingdom. Additionally, the United Kingdom's Olympic team competes under the name "Great Britain" or "Team GB".[41][42] -The adjective British is commonly used to refer to matters relating to the United Kingdom. The term has no definite legal connotation, but is used in law to refer to UK citizenship and matters to do with nationality.[43] People of the United Kingdom use a number of different terms to describe their national identity and may identify themselves as being British; or as being English, Scottish, Welsh, Northern Irish, or Irish;[44] or as being both.[45] -In 2006, a new design of British passport was introduced. Its first page shows the long form name of the state in English, Welsh and Scottish Gaelic.[46] In Welsh, the long form name of the state is "Teyrnas Unedig Prydain Fawr a Gogledd Iwerddon" with "Teyrnas Unedig" being used as a short form name on government websites.[47] In Scottish Gaelic, the long form is "Rìoghachd Aonaichte Bhreatainn is Èireann a Tuath" and the short form "Rìoghachd Aonaichte". -History -See also: History of the British Isles -Before 1707 - -Stonehenge, in Wiltshire, was erected around 2500 BC. -Main articles: History of England, History of Wales, History of Scotland, History of Ireland and History of the formation of the United Kingdom -Settlement by anatomically modern humans of what was to become the United Kingdom occurred in waves beginning by about 30,000 years ago.[48] By the end of the region's prehistoric period, the population is thought to have belonged, in the main, to a culture termed Insular Celtic, comprising Brythonic Britain and Gaelic Ireland.[49] The Roman conquest, beginning in 43 AD, and the 400-year rule of southern Britain, was followed by an invasion by Germanic Anglo-Saxon settlers, reducing the Brythonic area mainly to what was to become Wales and the historic Kingdom of Strathclyde.[50] Most of the region settled by the Anglo-Saxons became unified as the Kingdom of England in the 10th century.[51] Meanwhile, Gaelic-speakers in north west Britain (with connections to the north-east of Ireland and traditionally supposed to have migrated from there in the 5th century)[52][53] united with the Picts to create the Kingdom of Scotland in the 9th century.[54] -In 1066, the Normans invaded England from France and after its conquest, seized large parts of Wales, conquered much of Ireland and were invited to settle in Scotland, bringing to each country feudalism on the Northern French model and Norman-French culture.[55] The Norman elites greatly influenced, but eventually assimilated with, each of the local cultures.[56] Subsequent medieval English kings completed the conquest of Wales and made an unsuccessful attempt to annex Scotland. Thereafter, Scotland maintained its independence, albeit in near-constant conflict with England. The English monarchs, through inheritance of substantial territories in France and claims to the French crown, were also heavily involved in conflicts in France, most notably the Hundred Years War, while the Kings of Scots were in an alliance with the French during this period.[57] - -The Bayeux Tapestry depicts the Battle of Hastings and the events leading to it. -The early modern period saw religious conflict resulting from the Reformation and the introduction of Protestant state churches in each country.[58] Wales was fully incorporated into the Kingdom of England,[59] and Ireland was constituted as a kingdom in personal union with the English crown.[60] In what was to become Northern Ireland, the lands of the independent Catholic Gaelic nobility were confiscated and given to Protestant settlers from England and Scotland.[61] -In 1603, the kingdoms of England, Scotland and Ireland were united in a personal union when James VI, King of Scots, inherited the crowns of England and Ireland and moved his court from Edinburgh to London; each country nevertheless remained a separate political entity and retained its separate political, legal, and religious institutions.[62][63] -In the mid-17th century, all three kingdoms were involved in a series of connected wars (including the English Civil War) which led to the temporary overthrow of the monarchy and the establishment of the short-lived unitary republic of the Commonwealth of England, Scotland and Ireland.[64][65] -Although the monarchy was restored, it ensured (with the Glorious Revolution of 1688) that, unlike much of the rest of Europe, royal absolutism would not prevail, and a professed Catholic could never accede to the throne. The British constitution would develop on the basis of constitutional monarchy and the parliamentary system.[66] During this period, particularly in England, the development of naval power (and the interest in voyages of discovery) led to the acquisition and settlement of overseas colonies, particularly in North America.[67][68] -Since the Acts of Union of 1707 -Main article: History of the United Kingdom - -The Treaty of Union led to a single united kingdom encompassing all Great Britain. -On 1 May 1707, the united kingdom of Great Britain came into being, the result of Acts of Union being passed by the parliaments of England and Scotland to ratify the 1706 Treaty of Union and so unite the two kingdoms.[69][70][71] -In the 18th century, cabinet government developed under Robert Walpole, in practice the first prime minister (1721–1742). A series of Jacobite Uprisings sought to remove the Protestant House of Hanover from the British throne and restore the Catholic House of Stuart. The Jacobites were finally defeated at the Battle of Culloden in 1746, after which the Scottish Highlanders were brutally suppressed. The British colonies in North America that broke away from Britain in the American War of Independence became the United States of America in 1782. British imperial ambition turned elsewhere, particularly to India.[72] -During the 18th century, Britain was involved in the Atlantic slave trade. British ships transported an estimated 2 million slaves from Africa to the West Indies before banning the trade in 1807.[73] The term 'United Kingdom' became official in 1801 when the parliaments of Britain and Ireland each passed an Act of Union, uniting the two kingdoms and creating the United Kingdom of Great Britain and Ireland.[74] -In the early 19th century, the British-led Industrial Revolution began to transform the country. It slowly led to a shift in political power away from the old Tory and Whig landowning classes towards the new industrialists. An alliance of merchants and industrialists with the Whigs would lead to a new party, the Liberals, with an ideology of free trade and laissez-faire. In 1832 Parliament passed the Great Reform Act, which began the transfer of political power from the aristocracy to the middle classes. In the countryside, enclosure of the land was driving small farmers out. Towns and cities began to swell with a new urban working class. Few ordinary workers had the vote, and they created their own organisations in the form of trade unions. -Painting of a bloody battle. Horses and infantry fight or lie on grass. -The Battle of Waterloo marked the end of the Napoleonic Wars and the start of Pax Britannica. -After the defeat of France in the Revolutionary and Napoleonic Wars (1792–1815), the UK emerged as the principal naval and imperial power of the 19th century (with London the largest city in the world from about 1830).[75] Unchallenged at sea, British dominance was later described as Pax Britannica.[76][77] By the time of the Great Exhibition of 1851, Britain was described as the "workshop of the world".[78] The British Empire was expanded to include India, large parts of Africa and many other territories throughout the world. Alongside the formal control it exerted over its own colonies, British dominance of much of world trade meant that it effectively controlled the economies of many countries, such as China, Argentina and Siam.[79][80] Domestically, political attitudes favoured free trade and laissez-faire policies and a gradual widening of the voting franchise. During the century, the population increased at a dramatic rate, accompanied by rapid urbanisation, causing significant social and economic stresses.[81] After 1875, the UK's industrial monopoly was challenged by Germany and the USA. To seek new markets and sources of raw materials, the Conservative Party under Disraeli launched a period of imperialist expansion in Egypt, South Africa and elsewhere. Canada, Australia and New Zealand became self-governing dominions.[82] -Social reform and home rule for Ireland were important domestic issues after 1900. The Labour Party emerged from an alliance of trade unions and small Socialist groups in 1900, and suffragettes campaigned for women's right to vote before 1914. -Black-and-white photo of two dozen men in military uniforms and metal helmets sitting or standing in a muddy trench. -Infantry of the Royal Irish Rifles during the Battle of the Somme. More than 885,000 British soldiers died on the battlefields of World War I. -The UK fought with France, Russia and (after 1917) the US, against Germany and its allies in World War I (1914–18).[83] The UK armed forces were engaged across much of the British Empire and in several regions of Europe, particularly on the Western front.[84] The high fatalities of trench warfare caused the loss of much of a generation of men, with lasting social effects in the nation and a great disruption in the social order. -After the war, the UK received the League of Nations mandate over a number of former German and Ottoman colonies. The British Empire reached its greatest extent, covering a fifth of the world's land surface and a quarter of its population.[85] However, the UK had suffered 2.5 million casualties and finished the war with a huge national debt.[84] The rise of Irish Nationalism and disputes within Ireland over the terms of Irish Home Rule led eventually to the partition of the island in 1921,[86] and the Irish Free State became independent with Dominion status in 1922. Northern Ireland remained part of the United Kingdom.[87] A wave of strikes in the mid-1920s culminated in the UK General Strike of 1926. The UK had still not recovered from the effects of the war when the Great Depression (1929–32) occurred. This led to considerable unemployment and hardship in the old industrial areas, as well as political and social unrest in the 1930s. A coalition government was formed in 1931.[88] -The UK entered World War II by declaring war on Germany in 1939, after it had invaded Poland and Czechoslovakia. In 1940, Winston Churchill became prime minister and head of a coalition government. Despite the defeat of its European allies in the first year of the war, the UK continued the fight alone against Germany. In 1940, the RAF defeated the German Luftwaffe in a struggle for control of the skies in the Battle of Britain. The UK suffered heavy bombing during the Blitz. There were also eventual hard-fought victories in the Battle of the Atlantic, the North Africa campaign and Burma campaign. UK forces played an important role in the Normandy landings of 1944, achieved with its ally the US. After Germany's defeat, the UK was one of the Big Three powers who met to plan the post-war world; it was an original signatory to the Declaration of the United Nations. The UK became one of the five permanent members of the United Nations Security Council. However, the war left the UK severely weakened and depending financially on Marshall Aid and loans from the United States.[89] -Map of the world. Canada, the eastern United States, countries in east Africa, India, most of Australasia and some other countries are highlighted in pink. -Territories that were at one time part of the British Empire. Current British Overseas Territories are underlined in red. -In the immediate post-war years, the Labour government initiated a radical programme of reforms, which had a significant effect on British society in the following decades.[90] Major industries and public utilities were nationalised, a Welfare State was established, and a comprehensive, publicly funded healthcare system, the National Health Service, was created.[91] The rise of nationalism in the colonies coincided with Britain's now much-diminished economic position, so that a policy of decolonisation was unavoidable. Independence was granted to India and Pakistan in 1947.[92] Over the next three decades, most colonies of the British Empire gained their independence. Many became members of the Commonwealth of Nations.[93] -Although the UK was the third country to develop a nuclear weapons arsenal (with its first atomic bomb test in 1952), the new post-war limits of Britain's international role were illustrated by the Suez Crisis of 1956. The international spread of the English language ensured the continuing international influence of its literature and culture. From the 1960s onward, its popular culture was also influential abroad. As a result of a shortage of workers in the 1950s, the UK government encouraged immigration from Commonwealth countries. In the following decades, the UK became a multi-ethnic society.[94] Despite rising living standards in the late 1950s and 1960s, the UK's economic performance was not as successful as many of its competitors, such as West Germany and Japan. In 1973, the UK joined the European Economic Community (EEC), and when the EEC became the European Union (EU) in 1992, it was one of the 12 founding members. - -After the two vetos of France in 1961 and 1967, the UK entered in the European Union in 1973. In 1975, 67% of Britons voted yes to the permanence in the European Union. -From the late 1960s, Northern Ireland suffered communal and paramilitary violence (sometimes affecting other parts of the UK) conventionally known as the Troubles. It is usually considered to have ended with the Belfast "Good Friday" Agreement of 1998.[95][96][97] -Following a period of widespread economic slowdown and industrial strife in the 1970s, the Conservative Government of the 1980s initiated a radical policy of monetarism, deregulation, particularly of the financial sector (for example, Big Bang in 1986) and labour markets, the sale of state-owned companies (privatisation), and the withdrawal of subsidies to others.[98] This resulted in high unemployment and social unrest, but ultimately also economic growth, particularly in the services sector. From 1984, the economy was helped by the inflow of substantial North Sea oil revenues.[99] -Around the end of the 20th century there were major changes to the governance of the UK with the establishment of devolved administrations for Scotland, Wales and Northern Ireland.[13][100] The statutory incorporation followed acceptance of the European Convention on Human Rights. The UK is still a key global player diplomatically and militarily. It plays leading roles in the EU, UN and NATO. However, controversy surrounds some of Britain's overseas military deployments, particularly in Afghanistan and Iraq.[101] -The 2008 global financial crisis severely affected the UK economy. The coalition government of 2010 introduced austerity measures intended to tackle the substantial public deficits which resulted.[102] In 2014 the Scottish Government held a referendum on Scottish independence, with the majority of voters rejecting the independence proposal and opting to remain within the United Kingdom.[103] -Geography -Main article: Geography of the United Kingdom -Map of United Kingdom showing hilly regions to north and west, and flattest region in the south-east. -The topography of the UK -The total area of the United Kingdom is approximately 243,610 square kilometres (94,060 sq mi). The country occupies the major part of the British Isles[104] archipelago and includes the island of Great Britain, the northeastern one-sixth of the island of Ireland and some smaller surrounding islands. It lies between the North Atlantic Ocean and the North Sea with the south-east coast coming within 22 miles (35 km) of the coast of northern France, from which it is separated by the English Channel.[105] In 1993 10% of the UK was forested, 46% used for pastures and 25% cultivated for agriculture.[106] The Royal Greenwich Observatory in London is the defining point of the Prime Meridian.[107] -The United Kingdom lies between latitudes 49° to 61° N, and longitudes 9° W to 2° E. Northern Ireland shares a 224-mile (360 km) land boundary with the Republic of Ireland.[105] The coastline of Great Britain is 11,073 miles (17,820 km) long.[108] It is connected to continental Europe by the Channel Tunnel, which at 31 miles (50 km) (24 miles (38 km) underwater) is the longest underwater tunnel in the world.[109] -England accounts for just over half of the total area of the UK, covering 130,395 square kilometres (50,350 sq mi).[110] Most of the country consists of lowland terrain,[106] with mountainous terrain north-west of the Tees-Exe line; including the Cumbrian Mountains of the Lake District, the Pennines and limestone hills of the Peak District, Exmoor and Dartmoor. The main rivers and estuaries are the Thames, Severn and the Humber. England's highest mountain is Scafell Pike (978 metres (3,209 ft)) in the Lake District. Its principal rivers are the Severn, Thames, Humber, Tees, Tyne, Tweed, Avon, Exe and Mersey.[106] -Scotland accounts for just under a third of the total area of the UK, covering 78,772 square kilometres (30,410 sq mi)[111] and including nearly eight hundred islands,[112] predominantly west and north of the mainland; notably the Hebrides, Orkney Islands and Shetland Islands. The topography of Scotland is distinguished by the Highland Boundary Fault – a geological rock fracture – which traverses Scotland from Arran in the west to Stonehaven in the east.[113] The faultline separates two distinctively different regions; namely the Highlands to the north and west and the lowlands to the south and east. The more rugged Highland region contains the majority of Scotland's mountainous land, including Ben Nevis which at 1,343 metres (4,406 ft) is the highest point in the British Isles.[114] Lowland areas – especially the narrow waist of land between the Firth of Clyde and the Firth of Forth known as the Central Belt – are flatter and home to most of the population including Glasgow, Scotland's largest city, and Edinburgh, its capital and political centre. -A view of Ben Nevis in the distance, fronted by rolling plains -Ben Nevis, in Scotland, is the highest point in the British Isles -Wales accounts for less than a tenth of the total area of the UK, covering 20,779 square kilometres (8,020 sq mi).[115] Wales is mostly mountainous, though South Wales is less mountainous than North and mid Wales. The main population and industrial areas are in South Wales, consisting of the coastal cities of Cardiff, Swansea and Newport, and the South Wales Valleys to their north. The highest mountains in Wales are in Snowdonia and include Snowdon (Welsh: Yr Wyddfa) which, at 1,085 metres (3,560 ft), is the highest peak in Wales.[106] The 14, or possibly 15, Welsh mountains over 3,000 feet (914 m) high are known collectively as the Welsh 3000s. Wales has over 2,704 kilometres (1,680 miles) of coastline.[116] Several islands lie off the Welsh mainland, the largest of which is Anglesey (Ynys Môn) in the northwest. -Northern Ireland, separated from Great Britain by the Irish Sea and North Channel, has an area of 14,160 square kilometres (5,470 sq mi) and is mostly hilly. It includes Lough Neagh which, at 388 square kilometres (150 sq mi), is the largest lake in the British Isles by area.[117] The highest peak in Northern Ireland is Slieve Donard in the Mourne Mountains at 852 metres (2,795 ft).[106] -Climate -Main article: Climate of the United Kingdom -The United Kingdom has a temperate climate, with plentiful rainfall all year round.[105] The temperature varies with the seasons seldom dropping below −11 °C (12 °F) or rising above 35 °C (95 °F).[118] The prevailing wind is from the south-west and bears frequent spells of mild and wet weather from the Atlantic Ocean,[105] although the eastern parts are mostly sheltered from this wind since the majority of the rain falls over the western regions the eastern parts are therefore the driest. Atlantic currents, warmed by the Gulf Stream, bring mild winters; especially in the west where winters are wet and even more so over high ground. Summers are warmest in the south-east of England, being closest to the European mainland, and coolest in the north. Heavy snowfall can occur in winter and early spring on high ground, and occasionally settles to great depth away from the hills. -Administrative divisions -Main article: Administrative geography of the United Kingdom -Each country of the United Kingdom has its own system of administrative and geographic demarcation, whose origins often pre-date the formation of the United Kingdom. Thus there is "no common stratum of administrative unit encompassing the United Kingdom".[119] Until the 19th century there was little change to those arrangements, but there has since been a constant evolution of role and function.[120] Change did not occur in a uniform manner and the devolution of power over local government to Scotland, Wales and Northern Ireland means that future changes are unlikely to be uniform either. -The organisation of local government in England is complex, with the distribution of functions varying according to local arrangements. Legislation concerning local government in England is the responsibility of the UK parliament and the Government of the United Kingdom, as England has no devolved parliament. The upper-tier subdivisions of England are the nine Government office regions or European Union government office regions.[121] One region, Greater London, has had a directly elected assembly and mayor since 2000 following popular support for the proposal in a referendum.[122] It was intended that other regions would also be given their own elected regional assemblies, but a proposed assembly in the North East region was rejected by a referendum in 2004.[123] Below the regional tier, some parts of England have county councils and district councils and others have unitary authorities; while London consists of 32 London boroughs and the City of London. Councillors are elected by the first-past-the-post system in single-member wards or by the multi-member plurality system in multi-member wards.[124] -For local government purposes, Scotland is divided into 32 council areas, with wide variation in both size and population. The cities of Glasgow, Edinburgh, Aberdeen and Dundee are separate council areas, as is the Highland Council which includes a third of Scotland's area but only just over 200,000 people. Local councils are made up of elected councillors, of whom there are currently 1,222;[125] they are paid a part-time salary. Elections are conducted by single transferable vote in multi-member wards that elect either three or four councillors. Each council elects a Provost, or Convenor, to chair meetings of the council and to act as a figurehead for the area. Councillors are subject to a code of conduct enforced by the Standards Commission for Scotland.[126] The representative association of Scotland's local authorities is the Convention of Scottish Local Authorities (COSLA).[127] -Local government in Wales consists of 22 unitary authorities. These include the cities of Cardiff, Swansea and Newport which are unitary authorities in their own right.[128] Elections are held every four years under the first-past-the-post system.[129] The most recent elections were held in May 2012, except for the Isle of Anglesey. The Welsh Local Government Association represents the interests of local authorities in Wales.[130] -Local government in Northern Ireland has since 1973 been organised into 26 district councils, each elected by single transferable vote. Their powers are limited to services such as collecting waste, controlling dogs and maintaining parks and cemeteries.[131] On 13 March 2008 the executive agreed on proposals to create 11 new councils and replace the present system.[132] The next local elections were postponed until 2016 to facilitate this.[133] -Dependencies - -A view of the Caribbean Sea from the Cayman Islands, one of the world's foremost international financial centres[134] and tourist destinations.[135] -Main articles: British Overseas Territories, Crown dependencies and British Islands -The United Kingdom has sovereignty over seventeen territories which do not form part of the United Kingdom itself: fourteen British Overseas Territories[136] and three Crown dependencies.[137] -The fourteen British Overseas Territories are: Anguilla; Bermuda; the British Antarctic Territory; the British Indian Ocean Territory; the British Virgin Islands; the Cayman Islands; the Falkland Islands; Gibraltar; Montserrat; Saint Helena, Ascension and Tristan da Cunha; the Turks and Caicos Islands; the Pitcairn Islands; South Georgia and the South Sandwich Islands; and Sovereign Base Areas on Cyprus.[138] British claims in Antarctica are not universally recognised.[139] Collectively Britain's overseas territories encompass an approximate land area of 1,727,570 square kilometres (667,018 sq mi) and a population of approximately 260,000 people.[140] They are the remnants of the British Empire and several have specifically voted to remain British territories (Bermuda in 1995, Gibraltar in 2002 and the Falkland Islands in 2013).[141] -The Crown dependencies are possessions of the Crown, as opposed to overseas territories of the UK.[142] They comprise three independently administered jurisdictions: the Channel Islands of Jersey and Guernsey in the English Channel, and the Isle of Man in the Irish Sea. By mutual agreement, the British Government manages the islands' foreign affairs and defence and the UK Parliament has the authority to legislate on their behalf. However, internationally, they are regarded as "territories for which the United Kingdom is responsible".[143] The power to pass legislation affecting the islands ultimately rests with their own respective legislative assemblies, with the assent of the Crown (Privy Council or, in the case of the Isle of Man, in certain circumstances the Lieutenant-Governor).[144] Since 2005 each Crown dependency has had a Chief Minister as its head of government.[145] -Politics -Main articles: Politics of the United Kingdom, Monarchy of the United Kingdom and Elections in the United Kingdom -Elderly lady with a yellow hat and grey hair is smiling in outdoor setting. -Elizabeth II, Queen of the United Kingdom and the other Commonwealth realms -The United Kingdom is a unitary state under a constitutional monarchy. Queen Elizabeth II is the head of state of the UK as well as monarch of fifteen other independent Commonwealth countries. The monarch has "the right to be consulted, the right to encourage, and the right to warn".[146] The United Kingdom is one of only four countries in the world to have an uncodified constitution.[147][nb 7] The Constitution of the United Kingdom thus consists mostly of a collection of disparate written sources, including statutes, judge-made case law and international treaties, together with constitutional conventions. As there is no technical difference between ordinary statutes and "constitutional law", the UK Parliament can perform "constitutional reform" simply by passing Acts of Parliament, and thus has the political power to change or abolish almost any written or unwritten element of the constitution. However, no Parliament can pass laws that future Parliaments cannot change.[148] -Government -Main article: Government of the United Kingdom -The UK has a parliamentary government based on the Westminster system that has been emulated around the world: a legacy of the British Empire. The parliament of the United Kingdom that meets in the Palace of Westminster has two houses; an elected House of Commons and an appointed House of Lords. All bills passed are given Royal Assent before becoming law. -The position of prime minister,[nb 8] the UK's head of government,[149] belongs to the person most likely to command the confidence of the House of Commons; this individual is typically the leader of the political party or coalition of parties that holds the largest number of seats in that chamber. The prime minister chooses a cabinet and they are formally appointed by the monarch to form Her Majesty's Government. By convention, the Queen respects the prime minister's decisions of government.[150] -Large sand-coloured building of Gothic design beside brown river and road bridge. The building has several large towers, including large clock-tower. -The Palace of Westminster, seat of both houses of the Parliament of the United Kingdom -The cabinet is traditionally drawn from members of a prime minister's party or coalition and mostly from the House of Commons but always from both legislative houses, the cabinet being responsible to both. Executive power is exercised by the prime minister and cabinet, all of whom are sworn into the Privy Council of the United Kingdom, and become Ministers of the Crown. The current Prime Minister is David Cameron, who has been in office since 11 May 2010.[151] Cameron is the leader of the Conservative Party and heads a coalition with the Liberal Democrats. For elections to the House of Commons, the UK is currently divided into 650 constituencies,[152] each electing a single member of parliament (MP) by simple plurality. General elections are called by the monarch when the prime minister so advises. The Parliament Acts 1911 and 1949 require that a new election must be called no later than five years after the previous general election.[153] -The UK's three major political parties are the Conservative Party (Tories), the Labour Party and the Liberal Democrats, representing the British traditions of conservatism, socialism and social liberalism, respectively. During the 2010 general election these three parties won 622 out of 650 seats available in the House of Commons.[154][155] Most of the remaining seats were won by parties that contest elections only in one part of the UK: the Scottish National Party (Scotland only); Plaid Cymru (Wales only); and the Alliance Party, Democratic Unionist Party, Social Democratic and Labour Party and Sinn Féin (Northern Ireland only[nb 9]). In accordance with party policy, no elected Sinn Féin members of parliament have ever attended the House of Commons to speak on behalf of their constituents because of the requirement to take an oath of allegiance to the monarch. -Devolved administrations -Main articles: Devolution in the United Kingdom, Northern Ireland Executive, Scottish Government and Welsh Government -Modern one-story building with grass on roof and large sculpted grass area in front. Behind are residential buildings in a mixture of styles. -The Scottish Parliament Building in Holyrood is the seat of the Scottish Parliament. -Scotland, Wales and Northern Ireland each have their own government or executive, led by a First Minister (or, in the case of Northern Ireland, a diarchal First Minister and deputy First Minister), and a devolved unicameral legislature. England, the largest country of the United Kingdom, has no such devolved executive or legislature and is administered and legislated for directly by the UK government and parliament on all issues. This situation has given rise to the so-called West Lothian question which concerns the fact that members of parliament from Scotland, Wales and Northern Ireland can vote, sometimes decisively,[156] on matters that only affect England.[157] The McKay Commission reported on this matter in March 2013 recommending that laws affecting only England should need support from a majority of English members of parliament.[158] -The Scottish Government and Parliament have wide-ranging powers over any matter that has not been specifically reserved to the UK parliament, including education, healthcare, Scots law and local government.[159] At the 2011 elections the Scottish National Party won re-election and achieved an overall majority in the Scottish parliament, with its leader, Alex Salmond, as First Minister of Scotland.[160][161] In 2012, the UK and Scottish governments signed the Edinburgh Agreement setting out the terms for a referendum on Scottish independence in 2014, which was defeated 55% to 45%. -The Welsh Government and the National Assembly for Wales have more limited powers than those devolved to Scotland.[162] The Assembly is able to legislate on devolved matters through Acts of the Assembly, which require no prior consent from Westminster. The 2011 elections resulted in a minority Labour administration led by Carwyn Jones.[163] -The Northern Ireland Executive and Assembly have powers similar to those devolved to Scotland. The Executive is led by a diarchy representing unionist and nationalist members of the Assembly. Currently, Peter Robinson (Democratic Unionist Party) and Martin McGuinness (Sinn Féin) are First Minister and deputy First Minister respectively.[164] Devolution to Northern Ireland is contingent on participation by the Northern Ireland administration in the North-South Ministerial Council, where the Northern Ireland Executive cooperates and develops joint and shared policies with the Government of Ireland. The British and Irish governments co-operate on non-devolved matters affecting Northern Ireland through the British–Irish Intergovernmental Conference, which assumes the responsibilities of the Northern Ireland administration in the event of its non-operation. -The UK does not have a codified constitution and constitutional matters are not among the powers devolved to Scotland, Wales or Northern Ireland. Under the doctrine of parliamentary sovereignty, the UK Parliament could, in theory, therefore, abolish the Scottish Parliament, Welsh Assembly or Northern Ireland Assembly.[165][166] Indeed, in 1972, the UK Parliament unilaterally prorogued the Parliament of Northern Ireland, setting a precedent relevant to contemporary devolved institutions.[167] In practice, it would be politically difficult for the UK Parliament to abolish devolution to the Scottish Parliament and the Welsh Assembly, given the political entrenchment created by referendum decisions.[168] The political constraints placed upon the UK Parliament's power to interfere with devolution in Northern Ireland are even greater than in relation to Scotland and Wales, given that devolution in Northern Ireland rests upon an international agreement with the Government of Ireland.[169] -Law and criminal justice -Main article: Law of the United Kingdom - -The Royal Courts of Justice of England and Wales -The United Kingdom does not have a single legal system, as Article 19 of the 1706 Treaty of Union provided for the continuation of Scotland's separate legal system.[170] Today the UK has three distinct systems of law: English law, Northern Ireland law and Scots law. A new Supreme Court of the United Kingdom came into being in October 2009 to replace the Appellate Committee of the House of Lords.[171][172] The Judicial Committee of the Privy Council, including the same members as the Supreme Court, is the highest court of appeal for several independent Commonwealth countries, the British Overseas Territories and the Crown Dependencies.[173] -Both English law, which applies in England and Wales, and Northern Ireland law are based on common-law principles.[174] The essence of common law is that, subject to statute, the law is developed by judges in courts, applying statute, precedent and common sense to the facts before them to give explanatory judgements of the relevant legal principles, which are reported and binding in future similar cases (stare decisis).[175] The courts of England and Wales are headed by the Senior Courts of England and Wales, consisting of the Court of Appeal, the High Court of Justice (for civil cases) and the Crown Court (for criminal cases). The Supreme Court is the highest court in the land for both criminal and civil appeal cases in England, Wales and Northern Ireland and any decision it makes is binding on every other court in the same jurisdiction, often having a persuasive effect in other jurisdictions.[176] - -The High Court of Justiciary – the supreme criminal court of Scotland. -Scots law is a hybrid system based on both common-law and civil-law principles. The chief courts are the Court of Session, for civil cases,[177] and the High Court of Justiciary, for criminal cases.[178] The Supreme Court of the United Kingdom serves as the highest court of appeal for civil cases under Scots law.[179] Sheriff courts deal with most civil and criminal cases including conducting criminal trials with a jury, known as sheriff solemn court, or with a sheriff and no jury, known as sheriff summary Court.[180] The Scots legal system is unique in having three possible verdicts for a criminal trial: "guilty", "not guilty" and "not proven". Both "not guilty" and "not proven" result in an acquittal.[181] -Crime in England and Wales increased in the period between 1981 and 1995, though since that peak there has been an overall fall of 48% in crime from 1995 to 2007/08,[182] according to crime statistics. The prison population of England and Wales has almost doubled over the same period, to over 80,000, giving England and Wales the highest rate of incarceration in Western Europe at 147 per 100,000.[183] Her Majesty's Prison Service, which reports to the Ministry of Justice, manages most of the prisons within England and Wales. Crime in Scotland fell to its lowest recorded level for 32 years in 2009/10, falling by ten per cent.[184] At the same time Scotland's prison population, at over 8,000,[185] is at record levels and well above design capacity.[186] The Scottish Prison Service, which reports to the Cabinet Secretary for Justice, manages Scotland's prisons. -Foreign relations -Main article: Foreign relations of the United Kingdom - -The Prime Minister of the United Kingdom, David Cameron, and the President of the United States, Barack Obama, during the 2010 G-20 Toronto summit. -The UK is a permanent member of the United Nations Security Council, a member of NATO, the Commonwealth of Nations, G7, G8, G20, the OECD, the WTO, the Council of Europe, the OSCE, and is a member state of the European Union. The UK is said to have a "Special Relationship" with the United States and a close partnership with France—the "Entente cordiale"—and shares nuclear weapons technology with both countries.[187][188] The UK is also closely linked with the Republic of Ireland; the two countries share a Common Travel Area and co-operate through the British-Irish Intergovernmental Conference and the British-Irish Council. Britain's global presence and influence is further amplified through its trading relations, foreign investments, official development assistance and military engagements.[189] -Military - -Troopers of the Blues and Royals during the 2007 Trooping the Colour ceremony -Main article: British Armed Forces -The armed forces of the United Kingdom—officially, Her Majesty's Armed Forces—consist of three professional service branches: the Royal Navy and Royal Marines (forming the Naval Service), the British Army and the Royal Air Force.[190] The forces are managed by the Ministry of Defence and controlled by the Defence Council, chaired by the Secretary of State for Defence. The Commander-in-Chief is the British monarch, Elizabeth II, to whom members of the forces swear an oath of allegiance.[191] The Armed Forces are charged with protecting the UK and its overseas territories, promoting the UK's global security interests and supporting international peacekeeping efforts. They are active and regular participants in NATO, including the Allied Rapid Reaction Corps, as well as the Five Power Defence Arrangements, RIMPAC and other worldwide coalition operations. Overseas garrisons and facilities are maintained in Ascension Island, Belize, Brunei, Canada, Cyprus, Diego Garcia, the Falkland Islands, Germany, Gibraltar, Kenya and Qatar.[192] -The British armed forces played a key role in establishing the British Empire as the dominant world power in the 18th, 19th and early 20th centuries. Throughout its unique history the British forces have seen action in a number of major wars, such as the Seven Years' War, the Napoleonic Wars, the Crimean War, World War I and World War II—as well as many colonial conflicts. By emerging victorious from such conflicts, Britain has often been able to decisively influence world events. Since the end of the British Empire, the UK has nonetheless remained a major military power. Following the end of the Cold War, defence policy has a stated assumption that "the most demanding operations" will be undertaken as part of a coalition.[193] Setting aside the intervention in Sierra Leone, recent UK military operations in Bosnia, Kosovo, Afghanistan, Iraq and, most recently, Libya, have followed this approach. The last time the British military fought alone was the Falklands War of 1982. -According to various sources, including the Stockholm International Peace Research Institute and the International Institute for Strategic Studies, the United Kingdom has the fifth- or sixth-highest military expenditure in the world. Total defence spending currently accounts for around 2.4% of total national GDP.[22][23] -Economy -Main article: Economy of the United Kingdom - -The Bank of England – the central bank of the United Kingdom -The UK has a partially regulated market economy.[194] Based on market exchange rates the UK is today the sixth-largest economy in the world and the third-largest in Europe after Germany and France, having fallen behind France for the first time in over a decade in 2008.[195] HM Treasury, led by the Chancellor of the Exchequer, is responsible for developing and executing the British government's public finance policy and economic policy. The Bank of England is the UK's central bank and is responsible for issuing notes and coins in the nation's currency, the pound sterling. Banks in Scotland and Northern Ireland retain the right to issue their own notes, subject to retaining enough Bank of England notes in reserve to cover their issue. Pound sterling is the world's third-largest reserve currency (after the US Dollar and the Euro).[196] Since 1997 the Bank of England's Monetary Policy Committee, headed by the Governor of the Bank of England, has been responsible for setting interest rates at the level necessary to achieve the overall inflation target for the economy that is set by the Chancellor each year.[197] -The UK service sector makes up around 73% of GDP.[198] London is one of the three "command centres" of the global economy (alongside New York City and Tokyo),[199] it is the world's largest financial centre alongside New York,[200][201][202] and it has the largest city GDP in Europe.[203] Edinburgh is also one of the largest financial centres in Europe.[204] Tourism is very important to the British economy and, with over 27 million tourists arriving in 2004, the United Kingdom is ranked as the sixth major tourist destination in the world and London has the most international visitors of any city in the world.[205][206] The creative industries accounted for 7% GVA in 2005 and grew at an average of 6% per annum between 1997 and 2005.[207] - -The Airbus A350 has its wings and engines manufactured in the UK. -The Industrial Revolution started in the UK with an initial concentration on the textile industry,[208] followed by other heavy industries such as shipbuilding, coal mining and steelmaking.[209][210] -The empire was exploited as an overseas market for British products, allowing the UK to dominate international trade in the 19th century. As other nations industrialised, coupled with economic decline after two world wars, the United Kingdom began to lose its competitive advantage and heavy industry declined, by degrees, throughout the 20th century. Manufacturing remains a significant part of the economy but accounted for only 16.7% of national output in 2003.[211] -The automotive industry is a significant part of the UK manufacturing sector and employs over 800,000 people, with a turnover of some £52 billion, generating £26.6 billion of exports.[212] -The aerospace industry of the UK is the second- or third-largest national aerospace industry in the world depending upon the method of measurement and has an annual turnover of around £20 billion. The wings for the Airbus A380 and the A350 XWB are designed and manufactured at Airbus UK's world-leading Broughton facility, whilst over a quarter of the value of the Boeing 787 comes from UK manufacturers including Eaton (fuel subsystem pumps), Messier-Bugatti-Dowty (the landing gear) and Rolls-Royce (the engines). Other key names include GKN Aerospace – an expert in metallic and composite aerostructures that's involved in almost every civil and military fixed and rotary wing aircraft in production and development today.[213][214][215][216] -BAE Systems - plays a critical role on some of the world's biggest defence aerospace projects. The company makes large sections of the Typhoon Eurofighter at its sub-assembly plant in Salmesbury and assembles the aircraft for the RAF at its Warton Plant, near Preston. It is also a principal subcontractor on the F35 Joint Strike Fighter - the world's largest single defence project - for which it designs and manufactures a range of components including the aft fuselage, vertical and horizontal tail and wing tips and fuel system. As well as this it manufactures the Hawk, the world's most successful jet training aircraft.[216] Airbus UK also manufactures the wings for the A400m military transporter. Rolls-Royce, is the world's second-largest aero-engine manufacturer. Its engines power more than 30 types of commercial aircraft and it has more than 30,000 engines currently in service across both the civil and defence sectors. Agusta Westland designs and manufactures complete helicopters in the UK.[216] -The UK space industry is growing very fast. Worth £9.1bn in 2011 and employing 29,000 people, it is growing at a rate of some 7.5 per cent annually, according to its umbrella organisation, the UK Space Agency. Government strategy is for the space industry to be a £40bn business for the UK by 2030, capturing a 10 per cent share of the $250bn world market for commercial space technology.[216] On 16 July 2013, the British government pledged £60m to the Skylon project: this investment will provide support at a "crucial stage" to allow a full-scale prototype of the SABRE engine to be built. -The pharmaceutical industry plays an important role in the UK economy and the country has the third-highest share of global pharmaceutical R&D expenditures (after the United States and Japan).[217][218] -Agriculture is intensive, highly mechanised and efficient by European standards, producing about 60% of food needs with less than 1.6% of the labour force (535,000 workers).[219] Around two-thirds of production is devoted to livestock, one-third to arable crops. Farmers are subsidised by the EU's Common Agricultural Policy. The UK retains a significant, though much reduced fishing industry. It is also rich in a number of natural resources including coal, petroleum, natural gas, tin, limestone, iron ore, salt, clay, chalk, gypsum, lead, silica and an abundance of arable land. - -The City of London is the world's largest financial centre alongside New York[200][201][202] -In the final quarter of 2008 the UK economy officially entered recession for the first time since 1991.[220] Unemployment increased from 5.2% in May 2008 to 7.6% in May 2009 and by January 2012 the unemployment rate among 18 to 24-year-olds had risen from 11.9% to 22.5%, the highest since current records began in 1992.[221][222] Total UK government debt rose from 44.4% of GDP in 2007 to 82.9% of GDP in 2011.[223] In February 2013, the UK lost its top AAA credit rating for the first time since 1978.[224] -Inflation-adjusted wages in the UK fell by 3.2% between the third quarter of 2010 and the third quarter of 2012.[225] Since the 1980s, economic inequality has grown faster in the UK than in any other developed country.[226] -The poverty line in the UK is commonly defined as being 60% of the median household income.[nb 10] In 2007–2008 13.5 million people, or 22% of the population, lived below this line. This is a higher level of relative poverty than all but four other EU members.[227] In the same year 4.0 million children, 31% of the total, lived in households below the poverty line after housing costs were taken into account. This is a decrease of 400,000 children since 1998–1999.[228] The UK imports 40% of its food supplies.[229] The Office for National Statistics has estimated that in 2011, 14 million people were at risk of poverty or social exclusion, and that one person in 20 (5.1%) was now experiencing "severe material depression,"[230] up from 3 million people in 1977.[231][232] -Science and technology -Main article: Science and technology in the United Kingdom - -Charles Darwin (1809–82), whose theory of evolution by natural selection is the foundation of modern biological sciences -England and Scotland were leading centres of the Scientific Revolution from the 17th century[233] and the United Kingdom led the Industrial Revolution from the 18th century,[208] and has continued to produce scientists and engineers credited with important advances.[234] Major theorists from the 17th and 18th centuries include Isaac Newton, whose laws of motion and illumination of gravity have been seen as a keystone of modern science;[235] from the 19th century Charles Darwin, whose theory of evolution by natural selection was fundamental to the development of modern biology, and James Clerk Maxwell, who formulated classical electromagnetic theory; and more recently Stephen Hawking, who has advanced major theories in the fields of cosmology, quantum gravity and the investigation of black holes.[236] Major scientific discoveries from the 18th century include hydrogen by Henry Cavendish;[237] from the 20th century penicillin by Alexander Fleming,[238] and the structure of DNA, by Francis Crick and others.[239] Major engineering projects and applications by people from the UK in the 18th century include the steam locomotive, developed by Richard Trevithick and Andrew Vivian;[240] from the 19th century the electric motor by Michael Faraday, the incandescent light bulb by Joseph Swan,[241] and the first practical telephone, patented by Alexander Graham Bell;[242] and in the 20th century the world's first working television system by John Logie Baird and others,[243] the jet engine by Frank Whittle, the basis of the modern computer by Alan Turing, and the World Wide Web by Tim Berners-Lee.[244] -Scientific research and development remains important in British universities, with many establishing science parks to facilitate production and co-operation with industry.[245] Between 2004 and 2008 the UK produced 7% of the world's scientific research papers and had an 8% share of scientific citations, the third and second highest in the world (after the United States and China, and the United States, respectively).[246] Scientific journals produced in the UK include Nature, the British Medical Journal and The Lancet.[247] -Transport -Main article: Transport in the United Kingdom - -Heathrow Terminal 5 building. London Heathrow Airport has the most international passenger traffic of any airport in the world.[248][249] -A radial road network totals 29,145 miles (46,904 km) of main roads, 2,173 miles (3,497 km) of motorways and 213,750 miles (344,000 km) of paved roads.[105] In 2009 there were a total of 34 million licensed vehicles in Great Britain.[250] -The UK has a railway network of 10,072 miles (16,209 km) in Great Britain and 189 miles (304 km) in Northern Ireland. Railways in Northern Ireland are operated by NI Railways, a subsidiary of state-owned Translink. In Great Britain, the British Rail network was privatised between 1994 and 1997. Network Rail owns and manages most of the fixed assets (tracks, signals etc.). About 20 privately owned (and foreign state-owned railways including: Deutsche Bahn; SNCF and Nederlandse Spoorwegen) Train Operating Companies (including state-owned East Coast), operate passenger trains and carry over 18,000 passenger trains daily. There are also some 1,000 freight trains in daily operation.[105] The UK government is to spend £30 billion on a new high-speed railway line, HS2, to be operational by 2025.[251] Crossrail, under construction in London, Is Europe's largest construction project with a £15 billion projected cost.[252][253] -In the year from October 2009 to September 2010 UK airports handled a total of 211.4 million passengers.[254] In that period the three largest airports were London Heathrow Airport (65.6 million passengers), Gatwick Airport (31.5 million passengers) and London Stansted Airport (18.9 million passengers).[254] London Heathrow Airport, located 15 miles (24 km) west of the capital, has the most international passenger traffic of any airport in the world[248][249] and is the hub for the UK flag carrier British Airways, as well as for BMI and Virgin Atlantic.[255] -Energy -Main article: Energy in the United Kingdom - -An oil platform in the North Sea -In 2006, the UK was the world's ninth-largest consumer of energy and the 15th-largest producer.[256] The UK is home to a number of large energy companies, including two of the six oil and gas "supermajors" – BP and Royal Dutch Shell – and BG Group.[257][258] In 2011, 40% of the UK's electricity was produced by gas, 30% by coal, 19% by nuclear power and 4.2% by wind, hydro, biofuels and wastes.[259] -In 2009, the UK produced 1.5 million barrels per day (bbl/d) of oil and consumed 1.7 million bbl/d.[260] Production is now in decline and the UK has been a net importer of oil since 2005.[260] In 2010 the UK had around 3.1 billion barrels of proven crude oil reserves, the largest of any EU member state.[260] In 2009, 66.5% of the UK's oil supply was imported.[261] -In 2009, the UK was the 13th-largest producer of natural gas in the world and the largest producer in the EU.[262] Production is now in decline and the UK has been a net importer of natural gas since 2004.[262] In 2009, half of British gas was supplied from imports and this is expected to increase to at least 75% by 2015, as domestic reserves are depleted.[259] -Coal production played a key role in the UK economy in the 19th and 20th centuries. In the mid-1970s, 130 million tonnes of coal was being produced annually, not falling below 100 million tonnes until the early 1980s. During the 1980s and 1990s the industry was scaled back considerably. In 2011, the UK produced 18.3 million tonnes of coal.[263] In 2005 it had proven recoverable coal reserves of 171 million tons.[263] The UK Coal Authority has stated there is a potential to produce between 7 billion tonnes and 16 billion tonnes of coal through underground coal gasification (UCG) or 'fracking',[264] and that, based on current UK coal consumption, such reserves could last between 200 and 400 years.[265] However, environmental and social concerns have been raised over chemicals getting into the water table and minor earthquakes damaging homes.[266][267] -In the late 1990s, nuclear power plants contributed around 25% of total annual electricity generation in the UK, but this has gradually declined as old plants have been shut down and ageing-related problems affect plant availability. In 2012, the UK had 16 reactors normally generating about 19% of its electricity. All but one of the reactors will be retired by 2023. Unlike Germany and Japan, the UK intends to build a new generation of nuclear plants from about 2018.[259] -Demographics -Main article: Demographics of the United Kingdom - -Map of population density in the UK as at the 2011 census. -A census is taken simultaneously in all parts of the UK every ten years.[268] The Office for National Statistics is responsible for collecting data for England and Wales, the General Register Office for Scotland and the Northern Ireland Statistics and Research Agency each being responsible for censuses in their respective countries.[269] In the 2011 census the total population of the United Kingdom was 63,181,775.[270] It is the third-largest in the European Union, the fifth-largest in the Commonwealth and the 21st-largest in the world. 2010 was the third successive year in which natural change contributed more to population growth than net long-term international migration.[271][271] Between 2001 and 2011 the population increased by an average annual rate of approximately 0.7 per cent.[270] This compares to 0.3 per cent per year in the period 1991 to 2001 and 0.2 per cent in the decade 1981 to 1991.[271] The 2011 census also confirmed that the proportion of the population aged 0–14 has nearly halved (31 per cent in 1911 compared to 18 in 2011) and the proportion of older people aged 65 and over has more than trebled (from 5 to 16 per cent).[270] It has been estimated that the number of people aged 100 or over will rise steeply to reach over 626,000 by 2080.[272] -England's population in 2011 was found to be 53 million.[273] It is one of the most densely populated countries in the world, with 383 people resident per square kilometre in mid-2003,[274] with a particular concentration in London and the south-east.[275] The 2011 census put Scotland's population at 5.3 million,[276] Wales at 3.06 million and Northern Ireland at 1.81 million.[273] In percentage terms England has had the fastest growing population of any country of the UK in the period from 2001 to 2011, with an increase of 7.9%. -In 2012 the average total fertility rate (TFR) across the UK was 1.92 children per woman.[277] While a rising birth rate is contributing to current population growth, it remains considerably below the 'baby boom' peak of 2.95 children per woman in 1964,[278] below the replacement rate of 2.1, but higher than the 2001 record low of 1.63.[277] In 2012, Scotland had the lowest TFR at only 1.67, followed by Wales at 1.88, England at 1.94, and Northern Ireland at 2.03.[277] In 2011, 47.3% of births in the UK were to unmarried women.[279] A government figure estimated that there are 3.6 million homosexual people in Britain comprising 6 per cent of the population.[280] -view talk edit -view talk edit -Largest urban areas of the United Kingdom -United Kingdom 2011 census Built-up areas[281][282][283] -Rank Urban area Pop.

Welsh people could be the oldest ethnic group in the UK.[285] A 2006 genetic study shows that more than 50 per cent of England's gene pool contains Germanic Y chromosomes.[286] Another 2005 genetic analysis indicates that "about 75 per cent of the traceable ancestors of the modern British population had arrived in the British isles by about 6,200 years ago, at the start of the British Neolithic or Stone Age", and that the British broadly share a common ancestry with the Basque people.[287][288][289] -The UK has a history of small-scale non-white immigration, with Liverpool having the oldest Black population in the country dating back to at least the 1730s during the period of the African slave trade,[290] and the oldest Chinese community in Europe, dating to the arrival of Chinese seamen in the 19th century.[291] In 1950 there were probably fewer than 20,000 non-white residents in Britain, almost all born overseas.[292] -Since 1948 substantial immigration from Africa, the Caribbean and South Asia has been a legacy of ties forged by the British Empire. Migration from new EU member states in Central and Eastern Europe since 2004 has resulted in growth in these population groups but, as of 2008, the trend is reversing. Many of these migrants are returning to their home countries, leaving the size of these groups unknown.[293] In 2011, 86% of the population identified themselves as White, meaning 12.9% of the UK population identify themselves as of mixed ethnic minority. -Ethnic diversity varies significantly across the UK. 30.4% of London's population and 37.4% of Leicester's was estimated to be non-white in 2005,[294][295] whereas less than 5% of the populations of North East England, Wales and the South West were from ethnic minorities, according to the 2001 census.[296] In 2011, 26.5% of primary and 22.2% of secondary pupils at state schools in England were members of an ethnic minority.[297] -The non-white British population of England and Wales increased by 38% from 6.6 million in 2001 to 9.1 million in 2009.[298] The fastest-growing group was the mixed-ethnicity population, which doubled from 672,000 in 2001 to 986,600 in 2009. Also in the same period, a decrease of 36,000 white British people was recorded.[299] -Languages -Main article: Languages of the United Kingdom - -The English-speaking world. Countries in dark blue have a majority of native speakers; countries where English is an official but not a majority language are shaded in light blue. English is one of the official languages of the European Union[300] and the United Nations[301] -The UK's de facto official language is English.[302][303] It is estimated that 95% of the UK's population are monolingual English speakers.[304] 5.5% of the population are estimated to speak languages brought to the UK as a result of relatively recent immigration.[304] South Asian languages, including Bengali, Tamil, Punjabi, Hindi and Gujarati, are the largest grouping and are spoken by 2.7% of the UK population.[304] According to the 2011 census, Polish has become the second-largest language spoken in England and has 546,000 speakers.[305] -Four Celtic languages are spoken in the UK: Welsh; Irish; Scottish Gaelic; and Cornish. All are recognised as regional or minority languages, subject to specific measures of protection and promotion under the European Charter for Regional or Minority Languages[2][306] and the Framework Convention for the Protection of National Minorities.[307] In the 2001 Census over a fifth (21%) of the population of Wales said they could speak Welsh,[308] an increase from the 1991 Census (18%).[309] In addition it is estimated that about 200,000 Welsh speakers live in England.[310] In the same census in Northern Ireland 167,487 people (10.4%) stated that they had "some knowledge of Irish" (see Irish language in Northern Ireland), almost exclusively in the nationalist (mainly Catholic) population. Over 92,000 people in Scotland (just under 2% of the population) had some Gaelic language ability, including 72% of those living in the Outer Hebrides.[311] The number of schoolchildren being taught through Welsh, Scottish Gaelic and Irish is increasing.[312] Among emigrant-descended populations some Scottish Gaelic is still spoken in Canada (principally Nova Scotia and Cape Breton Island),[313] and Welsh in Patagonia, Argentina.[314] -Scots, a language descended from early northern Middle English, has limited recognition alongside its regional variant, Ulster Scots in Northern Ireland, without specific commitments to protection and promotion.[2][315] -It is compulsory for pupils to study a second language up to the age of 14 in England,[316] and up to age 16 in Scotland. French and German are the two most commonly taught second languages in England and Scotland. All pupils in Wales are taught Welsh as a second language up to age 16, or are taught in Welsh.[317] -Religion -Main article: Religion in the United Kingdom - -Westminster Abbey is used for the coronation of British monarchs -Forms of Christianity have dominated religious life in what is now the United Kingdom for over 1,400 years.[318] Although a majority of citizens still identify with Christianity in many surveys, regular church attendance has fallen dramatically since the middle of the 20th century,[319] while immigration and demographic change have contributed to the growth of other faiths, most notably Islam.[320] This has led some commentators to variously describe the UK as a multi-faith,[321] secularised,[322] or post-Christian society.[323] -In the 2001 census 71.6% of all respondents indicated that they were Christians, with the next largest faiths (by number of adherents) being Islam (2.8%), Hinduism (1.0%), Sikhism (0.6%), Judaism (0.5%), Buddhism (0.3%) and all other religions (0.3%).[324] 15% of respondents stated that they had no religion, with a further 7% not stating a religious preference.[325] A Tearfund survey in 2007 showed only one in ten Britons actually attend church weekly.[326] Between the 2001 and 2011 census there was a decrease in the amount of people who identified as Christian by 12%, whilst the percentage of those reporting no religious affiliation doubled. This contrasted with growth in the other main religious group categories, with the number of Muslims increasing by the most substantial margin to a total of about 5%.[327] -The Church of England is the established church in England.[328] It retains a representation in the UK Parliament and the British monarch is its Supreme Governor.[329] In Scotland the Presbyterian Church of Scotland is recognised as the national church. It is not subject to state control, and the British monarch is an ordinary member, required to swear an oath to "maintain and preserve the Protestant Religion and Presbyterian Church Government" upon his or her accession.[330][331] The (Anglican) Church in Wales was disestablished in 1920 and, as the (Anglican) Church of Ireland was disestablished in 1870 before the partition of Ireland, there is no established church in Northern Ireland.[332] Although there are no UK-wide data in the 2001 census on adherence to individual Christian denominations, it has been estimated that 62% of Christians are Anglican, 13.5% Catholic, 6% Presbyterian, 3.4% Methodist with small numbers of other Protestant denominations such as Open Brethren, and Orthodox churches.[333] -Migration -Main article: Immigration to the United Kingdom since 1922 -See also: Foreign-born population of the United Kingdom - -Estimated foreign-born population by country of birth, April 2007 – March 2008 -The United Kingdom has experienced successive waves of migration. The Great Famine in Ireland, then part of the United Kingdom, resulted in perhaps a million people migrating to Great Brtain.[334] Unable to return to Poland at the end of World War II, over 120,000 Polish veterans remained in the UK permanently.[335] After World War II, there was significant immigration from the colonies and newly independent former colonies, partly as a legacy of empire and partly driven by labour shortages. Many of these migrants came from the Caribbean and the Indian subcontinent.[336] The British Asian population has increased from 2.2 million in 2001 to over 4.2 million in 2011.[337] -One of the more recent trends in migration has been the arrival of workers from the new EU member states in Eastern Europe. In 2010, there were 7.0 million foreign-born residents in the UK, corresponding to 11.3% of the total population. Of these, 4.76 million (7.7%) were born outside the EU and 2.24 million (3.6%) were born in another EU Member State.[338] The proportion of foreign-born people in the UK remains slightly below that of many other European countries.[339] However, immigration is now contributing to a rising population[340] with arrivals and UK-born children of migrants accounting for about half of the population increase between 1991 and 2001. Analysis of Office for National Statistics (ONS) data shows that a net total of 2.3 million migrants moved to the UK in the 15 years from 1991 to 2006.[341][342] In 2008 it was predicted that migration would add 7 million to the UK population by 2031,[343] though these figures are disputed.[344] The ONS reported that net migration rose from 2009 to 2010 by 21 per cent to 239,000.[345] In 2011 the net increase was 251,000: immigration was 589,000, while the number of people emigrating (for more than 12 months) was 338,000.[346][347] -195,046 foreign nationals became British citizens in 2010,[348] compared to 54,902 in 1999.[348][349] A record 241,192 people were granted permanent settlement rights in 2010, of whom 51 per cent were from Asia and 27 per cent from Africa.[350] 25.5 per cent of babies born in England and Wales in 2011 were born to mothers born outside the UK, according to official statistics released in 2012.[351] -Citizens of the European Union, including those of the UK, have the right to live and work in any EU member state.[352] The UK applied temporary restrictions to citizens of Romania and Bulgaria, which joined the EU in January 2007.[353] Research conducted by the Migration Policy Institute for the Equality and Human Rights Commission suggests that, between May 2004 and September 2009, 1.5 million workers migrated from the new EU member states to the UK, two-thirds of them Polish, but that many subsequently returned home, resulting in a net increase in the number of nationals of the new member states in the UK of some 700,000 over that period.[354][355] The late-2000s recession in the UK reduced the economic incentive for Poles to migrate to the UK,[356] the migration becoming temporary and circular.[357] In 2009, for the first time since enlargement, more nationals of the eight central and eastern European states that had joined the EU in 2004 left the UK than arrived.[358] In 2011, citizens of the new EU member states made up 13% of the immigrants entering the country.[346] - -Estimated number of British citizens living overseas by country, 2006 -The UK government has introduced a points-based immigration system for immigration from outside the European Economic Area to replace former schemes, including the Scottish Government's Fresh Talent Initiative.[359] In June 2010 the UK government introduced a temporary limit of 24,000 on immigration from outside the EU, aiming to discourage applications before a permanent cap was imposed in April 2011.[360] The cap has caused tension within the coalition: business secretary Vince Cable has argued that it is harming British businesses.[361] -Emigration was an important feature of British society in the 19th century. Between 1815 and 1930 around 11.4 million people emigrated from Britain and 7.3 million from Ireland. Estimates show that by the end of the 20th century some 300 million people of British and Irish descent were permanently settled around the globe.[362] Today, at least 5.5 million UK-born people live abroad,[363][364][365] mainly in Australia, Spain, the United States and Canada.[363][366] -Education -Main article: Education in the United Kingdom -See also: Education in England, Education in Northern Ireland, Education in Scotland and Education in Wales - -King's College, part of the University of Cambridge, which was founded in 1209 -Education in the United Kingdom is a devolved matter, with each country having a separate education system. -Whilst education in England is the responsibility of the Secretary of State for Education, the day-to-day administration and funding of state schools is the responsibility of local authorities.[367] Universally free of charge state education was introduced piecemeal between 1870 and 1944.[368][369] Education is now mandatory from ages five to sixteen (15 if born in late July or August). In 2011, the Trends in International Mathematics and Science Study (TIMSS) rated 13–14-year-old pupils in England and Wales 10th in the world for maths and 9th for science.[370] The majority of children are educated in state-sector schools, a small proportion of which select on the grounds of academic ability. Two of the top ten performing schools in terms of GCSE results in 2006 were state-run grammar schools. Over half of students at the leading universities of Cambridge and Oxford had attended state schools.[371] Despite a fall in actual numbers the proportion of children in England attending private schools has risen to over 7%.[372] In 2010, more than 45% of places at the University of Oxford and 40% at the University of Cambridge were taken by students from private schools, even though they educate just 7% of the population.[373] England has the two oldest universities in English-speaking world, Universities of Oxford and Cambridge (jointly known as "Oxbridge") with history of over eight centuries. The United Kingdom has 9 universities featured in the Times Higher Education top 100 rankings, making it second to the United States in terms of representation.[374] - -Queen's University Belfast, built in 1849[375] -Education in Scotland is the responsibility of the Cabinet Secretary for Education and Lifelong Learning, with day-to-day administration and funding of state schools the responsibility of Local Authorities. Two non-departmental public bodies have key roles in Scottish education. The Scottish Qualifications Authority is responsible for the development, accreditation, assessment and certification of qualifications other than degrees which are delivered at secondary schools, post-secondary colleges of further education and other centres.[376] The Learning and Teaching Scotland provides advice, resources and staff development to education professionals.[377] Scotland first legislated for compulsory education in 1496.[378] The proportion of children in Scotland attending private schools is just over 4%, and it has been rising slowly in recent years.[379] Scottish students who attend Scottish universities pay neither tuition fees nor graduate endowment charges, as fees were abolished in 2001 and the graduate endowment scheme was abolished in 2008.[380] -The Welsh Government has responsibility for education in Wales. A significant number of Welsh students are taught either wholly or largely in the Welsh language; lessons in Welsh are compulsory for all until the age of 16.[381] There are plans to increase the provision of Welsh-medium schools as part of the policy of creating a fully bilingual Wales. -Education in Northern Ireland is the responsibility of the Minister of Education and the Minister for Employment and Learning, although responsibility at a local level is administered by five education and library boards covering different geographical areas. The Council for the Curriculum, Examinations & Assessment (CCEA) is the body responsible for advising the government on what should be taught in Northern Ireland's schools, monitoring standards and awarding qualifications.[382] -A government commission's report in 2014 found that privately educated people comprise 7% of the general population of the UK but much larger percentages of the top professions, the most extreme case quoted being 71% of senior judges.[383][384] -Healthcare -Main article: Healthcare in the United Kingdom - -The Royal Aberdeen Children's Hospital, an NHS Scotland specialist children's hospital -Healthcare in the United Kingdom is a devolved matter and each country has its own system of private and publicly funded health care, together with alternative, holistic and complementary treatments. Public healthcare is provided to all UK permanent residents and is mostly free at the point of need, being paid for from general taxation. The World Health Organization, in 2000, ranked the provision of healthcare in the United Kingdom as fifteenth best in Europe and eighteenth in the world.[385][386] -Regulatory bodies are organised on a UK-wide basis such as the General Medical Council, the Nursing and Midwifery Council and non-governmental-based, such as the Royal Colleges. However, political and operational responsibility for healthcare lies with four national executives; healthcare in England is the responsibility of the UK Government; healthcare in Northern Ireland is the responsibility of the Northern Ireland Executive; healthcare in Scotland is the responsibility of the Scottish Government; and healthcare in Wales is the responsibility of the Welsh Assembly Government. Each National Health Service has different policies and priorities, resulting in contrasts.[387][388] -Since 1979 expenditure on healthcare has been increased significantly to bring it closer to the European Union average.[389] The UK spends around 8.4 per cent of its gross domestic product on healthcare, which is 0.5 percentage points below the Organisation for Economic Co-operation and Development average and about one percentage point below the average of the European Union.[390] -Culture -Main article: Culture of the United Kingdom -The culture of the United Kingdom has been influenced by many factors including: the nation's island status; its history as a western liberal democracy and a major power; as well as being a political union of four countries with each preserving elements of distinctive traditions, customs and symbolism. As a result of the British Empire, British influence can be observed in the language, culture and legal systems of many of its former colonies including Australia, Canada, India, Ireland, New Zealand, South Africa and the United States. The substantial cultural influence of the United Kingdom has led it to be described as a "cultural superpower."[391][392] -Literature -Main article: British literature - -The Chandos portrait, believed to depict William Shakespeare -'British literature' refers to literature associated with the United Kingdom, the Isle of Man and the Channel Islands. Most British literature is in the English language. In 2005, some 206,000 books were published in the United Kingdom and in 2006 it was the largest publisher of books in the world.[393] -The English playwright and poet William Shakespeare is widely regarded as the greatest dramatist of all time,[394][395][396] and his contemporaries Christopher Marlowe and Ben Jonson have also been held in continuous high esteem. More recently the playwrights Alan Ayckbourn, Harold Pinter, Michael Frayn, Tom Stoppard and David Edgar have combined elements of surrealism, realism and radicalism. -Notable pre-modern and early-modern English writers include Geoffrey Chaucer (14th century), Thomas Malory (15th century), Sir Thomas More (16th century), John Bunyan (17th century) and John Milton (17th century). In the 18th century Daniel Defoe (author of Robinson Crusoe) and Samuel Richardson were pioneers of the modern novel. In the 19th century there followed further innovation by Jane Austen, the gothic novelist Mary Shelley, the children's writer Lewis Carroll, the Brontë sisters, the social campaigner Charles Dickens, the naturalist Thomas Hardy, the realist George Eliot, the visionary poet William Blake and romantic poet William Wordsworth. 20th-century English writers include the science-fiction novelist H. G. Wells; the writers of children's classics Rudyard Kipling, A. A. Milne (the creator of Winnie-the-Pooh), Roald Dahl and Enid Blyton; the controversial D. H. Lawrence; the modernist Virginia Woolf; the satirist Evelyn Waugh; the prophetic novelist George Orwell; the popular novelists W. Somerset Maugham and Graham Greene; the crime writer Agatha Christie (the best-selling novelist of all time);[397] Ian Fleming (the creator of James Bond); the poets T.S. Eliot, Philip Larkin and Ted Hughes; the fantasy writers J. R. R. Tolkien, C. S. Lewis and J. K. Rowling; the graphic novelist Alan Moore, whose novel Watchmen is often cited by critics as comic's greatest series and graphic novel[398] and one of the best-selling graphic novels ever published.[399] - -A photograph of Victorian era novelist Charles Dickens -Scotland's contributions include the detective writer Arthur Conan Doyle (the creator of Sherlock Holmes), romantic literature by Sir Walter Scott, the children's writer J. M. Barrie, the epic adventures of Robert Louis Stevenson and the celebrated poet Robert Burns. More recently the modernist and nationalist Hugh MacDiarmid and Neil M. Gunn contributed to the Scottish Renaissance. A more grim outlook is found in Ian Rankin's stories and the psychological horror-comedy of Iain Banks. Scotland's capital, Edinburgh, was UNESCO's first worldwide City of Literature.[400] -Britain's oldest known poem, Y Gododdin, was composed in Yr Hen Ogledd (The Old North), most likely in the late 6th century. It was written in Cumbric or Old Welsh and contains the earliest known reference to King Arthur.[401] From around the seventh century, the connection between Wales and the Old North was lost, and the focus of Welsh-language culture shifted to Wales, where Arthurian legend was further developed by Geoffrey of Monmouth.[402] Wales's most celebrated medieval poet, Dafydd ap Gwilym (fl.1320–1370), composed poetry on themes including nature, religion and especially love. He is widely regarded as one of the greatest European poets of his age.[403] Until the late 19th century the majority of Welsh literature was in Welsh and much of the prose was religious in character. Daniel Owen is credited as the first Welsh-language novelist, publishing Rhys Lewis in 1885. The best-known of the Anglo-Welsh poets are both Thomases. Dylan Thomas became famous on both sides of the Atlantic in the mid-20th century. He is remembered for his poetry – his "Do not go gentle into that good night; Rage, rage against the dying of the light." is one of the most quoted couplets of English language verse – and for his 'play for voices', Under Milk Wood.

George Frideric Handel, although born German, was a naturalised British citizen[411] and some of his best works, such as Messiah, were written in the English language.[412] Andrew Lloyd Webber has achieved enormous worldwide commercial success and is a prolific composer of musical theatre, works which have dominated London's West End for a number of years and have travelled to Broadway in New York.[413] -The Beatles have international sales of over one billion units and are the biggest-selling and most influential band in the history of popular music.[408][409][410][414] Other prominent British contributors to have influenced popular music over the last 50 years include; The Rolling Stones, Led Zeppelin, Pink Floyd, Queen, the Bee Gees, and Elton John, all of whom have world wide record sales of 200 million or more.[415][416][417][418][419][420] The Brit Awards are the BPI's annual music awards, and some of the British recipients of the Outstanding Contribution to Music award include; The Who, David Bowie, Eric Clapton, Rod Stewart and The Police.[421] More recent UK music acts that have had international success include Coldplay, Radiohead, Oasis, Spice Girls, Robbie Williams, Amy Winehouse and Adele.[422] -A number of UK cities are known for their music. Acts from Liverpool have had more UK chart number one hit singles per capita (54) than any other city worldwide.[423] Glasgow's contribution to music was recognised in 2008 when it was named a UNESCO City of Music, one of only three cities in the world to have this honour.[424] -Visual art -Main article: Art of the United Kingdom - -J. M. W. Turner self-portrait, oil on canvas, c. 1799 -The history of British visual art forms part of western art history. Major British artists include: the Romantics William Blake, John Constable, Samuel Palmer and J.M.W. Turner; the portrait painters Sir Joshua Reynolds and Lucian Freud; the landscape artists Thomas Gainsborough and L. S. Lowry; the pioneer of the Arts and Crafts Movement William Morris; the figurative painter Francis Bacon; the Pop artists Peter Blake, Richard Hamilton and David Hockney; the collaborative duo Gilbert and George; the abstract artist Howard Hodgkin; and the sculptors Antony Gormley, Anish Kapoor and Henry Moore. During the late 1980s and 1990s the Saatchi Gallery in London helped to bring to public attention a group of multi-genre artists who would become known as the "Young British Artists": Damien Hirst, Chris Ofili, Rachel Whiteread, Tracey Emin, Mark Wallinger, Steve McQueen, Sam Taylor-Wood and the Chapman Brothers are among the better-known members of this loosely affiliated movement. -The Royal Academy in London is a key organisation for the promotion of the visual arts in the United Kingdom. Major schools of art in the UK include: the six-school University of the Arts London, which includes the Central Saint Martins College of Art and Design and Chelsea College of Art and Design; Goldsmiths, University of London; the Slade School of Fine Art (part of University College London); the Glasgow School of Art; the Royal College of Art; and The Ruskin School of Drawing and Fine Art (part of the University of Oxford). The Courtauld Institute of Art is a leading centre for the teaching of the history of art. Important art galleries in the United Kingdom include the National Gallery, National Portrait Gallery, Tate Britain and Tate Modern (the most-visited modern art gallery in the world, with around 4.7 million visitors per year).[425] -Cinema -Main article: Cinema of the United Kingdom - -Film director Alfred Hitchcock -The United Kingdom has had a considerable influence on the history of the cinema. The British directors Alfred Hitchcock, whose film Vertigo is considered by some critics as the best film of all time,[426] and David Lean are among the most critically acclaimed of all-time.[427] Other important directors including Charlie Chaplin,[428] Michael Powell,[429] Carol Reed[430] and Ridley Scott.[431] Many British actors have achieved international fame and critical success, including: Julie Andrews,[432] Richard Burton,[433] Michael Caine,[434] Charlie Chaplin,[435] Sean Connery,[436] Vivien Leigh,[437] David Niven,[438] Laurence Olivier,[439] Peter Sellers,[440] Kate Winslet,[441] and Daniel Day-Lewis, the only person to win an Oscar in the best actor category three times.[442] Some of the most commercially successful films of all time have been produced in the United Kingdom, including the two highest-grossing film franchises (Harry Potter and James Bond).[443] Ealing Studios has a claim to being the oldest continuously working film studio in the world.[444] -Despite a history of important and successful productions, the industry has often been characterised by a debate about its identity and the level of American and European influence. British producers are active in international co-productions and British actors, directors and crew feature regularly in American films. Many successful Hollywood films have been based on British people, stories or events, including Titanic, The Lord of the Rings, Pirates of the Caribbean. -In 2009, British films grossed around $2 billion worldwide and achieved a market share of around 7% globally and 17% in the United Kingdom.[445] UK box-office takings totalled £944 million in 2009, with around 173 million admissions.[445] The British Film Institute has produced a poll ranking of what it considers to be the 100 greatest British films of all time, the BFI Top 100 British films.[446] The annual British Academy Film Awards, hosted by the British Academy of Film and Television Arts, are the British equivalent of the Oscars.[447] -Media -Main article: Media of the United Kingdom - -Broadcasting House in London, headquarters of the BBC, the oldest and largest broadcaster in the world.[448][449][450] -The BBC, founded in 1922, is the UK's publicly funded radio, television and Internet broadcasting corporation, and is the oldest and largest broadcaster in the world.[448][449][450] It operates numerous television and radio stations in the UK and abroad and its domestic services are funded by the television licence.[451][452] Other major players in the UK media include ITV plc, which operates 11 of the 15 regional television broadcasters that make up the ITV Network,[453] and News Corporation, which owns a number of national newspapers through News International such as the most popular tabloid The Sun and the longest-established daily "broadsheet" The Times,[454] as well as holding a large stake in satellite broadcaster British Sky Broadcasting.[455] London dominates the media sector in the UK: national newspapers and television and radio are largely based there, although Manchester is also a significant national media centre. Edinburgh and Glasgow, and Cardiff, are important centres of newspaper and broadcasting production in Scotland and Wales respectively.[456] The UK publishing sector, including books, directories and databases, journals, magazines and business media, newspapers and news agencies, has a combined turnover of around £20 billion and employs around 167,000 people.[457] -In 2009, it was estimated that individuals viewed a mean of 3.75 hours of television per day and 2.81 hours of radio. In that year the main BBC public service broadcasting channels accounted for an estimated 28.4% of all television viewing; the three main independent channels accounted for 29.5% and the increasingly important other satellite and digital channels for the remaining 42.1%.[458] Sales of newspapers have fallen since the 1970s and in 2009 42% of people reported reading a daily national newspaper.[459] In 2010 82.5% of the UK population were Internet users, the highest proportion amongst the 20 countries with the largest total number of users in that year.[460] -Philosophy -Main article: British philosophy -The United Kingdom is famous for the tradition of 'British Empiricism', a branch of the philosophy of knowledge that states that only knowledge verified by experience is valid, and 'Scottish Philosophy', sometimes referred to as the 'Scottish School of Common Sense'.[461] The most famous philosophers of British Empiricism are John Locke, George Berkeley and David Hume; while Dugald Stewart, Thomas Reid and William Hamilton were major exponents of the Scottish "common sense" school. Two Britons are also notable for a theory of moral philosophy utilitarianism, first used by Jeremy Bentham and later by John Stuart Mill in his short work Utilitarianism.[462][463] Other eminent philosophers from the UK and the unions and countries that preceded it include Duns Scotus, John Lilburne, Mary Wollstonecraft, Sir Francis Bacon, Adam Smith, Thomas Hobbes, William of Ockham, Bertrand Russell and A.J. "Freddie" Ayer. Foreign-born philosophers who settled in the UK include Isaiah Berlin, Karl Marx, Karl Popper and Ludwig Wittgenstein. -Sport -Main article: Sport in the United Kingdom - -Wembley Stadium, London, home of the England national football team, is one of the most expensive stadia ever built.[464] -Major sports, including association football, tennis, rugby union, rugby league, golf, boxing, rowing and cricket, originated or were substantially developed in the UK and the states that preceded it. With the rules and codes of many modern sports invented and codified in late 19th-century Victorian Britain, in 2012, the President of the IOC, Jacques Rogge, stated; "This great, sports-loving country is widely recognized as the birthplace of modern sport. It was here that the concepts of sportsmanship and fair play were first codified into clear rules and regulations. It was here that sport was included as an educational tool in the school curriculum".[465][466] -In most international competitions, separate teams represent England, Scotland and Wales. Northern Ireland and the Republic of Ireland usually field a single team representing all of Ireland, with notable exceptions being association football and the Commonwealth Games. In sporting contexts, the English, Scottish, Welsh and Irish / Northern Irish teams are often referred to collectively as the Home Nations. There are some sports in which a single team represents the whole of United Kingdom, including the Olympics, where the UK is represented by the Great Britain team. The 1908, 1948 and 2012 Summer Olympics were held in London, making it the first city to host the games three times. Britain has participated in every modern Olympic Games to date and is third in the medal count. -A 2003 poll found that football is the most popular sport in the United Kingdom.[467] Each of the Home Nations has its own football association, national team and league system. The English top division, the Premier League, is the most watched football league in the world.[468] The first-ever international football match was contested by England and Scotland on 30 November 1872.[469] England, Scotland, Wales and Northern Ireland compete as separate countries in international competitions.[470] A Great Britain Olympic football team was assembled for the first time to compete in the London 2012 Olympic Games. However, the Scottish, Welsh and Northern Irish football associations declined to participate, fearing that it would undermine their independent status – a fear confirmed by FIFA president Sepp Blatter.[471] - -The Millennium Stadium, Cardiff, opened for the 1999 Rugby World Cup. -Cricket was invented in England. The England cricket team, controlled by the England and Wales Cricket Board,[472] is the only national team in the UK with Test status. Team members are drawn from the main county sides, and include both English and Welsh players. Cricket is distinct from football and rugby where Wales and England field separate national teams, although Wales had fielded its own team in the past. Irish and Scottish players have played for England because neither Scotland nor Ireland have Test status and have only recently started to play in One Day Internationals.[473][474] Scotland, England (and Wales), and Ireland (including Northern Ireland) have competed at the Cricket World Cup, with England reaching the finals on three occasions. There is a professional league championship in which clubs representing 17 English counties and 1 Welsh county compete.[475] -Rugby league is a popular sport in some regions of the UK. It originated in Huddersfield and is generally played in Northern England.[476] A single 'Great Britain Lions' team had competed in the Rugby League World Cup and Test match games, but this changed in 2008 when England, Scotland and Ireland competed as separate nations.[477] Great Britain is still being retained as the full national team for Ashes tours against Australia, New Zealand and France. Super League is the highest level of professional rugby league in the UK and Europe. It consists of 11 teams from Northern England, 1 from London, 1 from Wales and 1 from France. -In rugby union, England, Scotland, Wales, Ireland, France and Italy compete in the Six Nations Championship; the premier international tournament in the northern hemisphere. Sport governing bodies in England, Scotland, Wales and Ireland organise and regulate the game separately.[478] If any of the British teams or the Irish team beat the other three in a tournament, then it is awarded the Triple Crown.[479] - -The Wimbledon Championships, a Grand Slam tennis tournament, is held in Wimbledon, London every June or July. -Thoroughbred racing, which originated under Charles II of England as the "sport of kings", is popular throughout the UK with world-famous races including the Grand National, the Epsom Derby, Royal Ascot and the Cheltenham National Hunt Festival (including the Cheltenham Gold Cup). The UK has proved successful in the international sporting arena in rowing. -The UK is closely associated with motorsport. Many teams and drivers in Formula One (F1) are based in the UK, and the country has won more drivers' and constructors' titles than any other. The UK hosted the very first F1 Grand Prix in 1950 at Silverstone, the current location of the British Grand Prix held each year in July. The country also hosts legs of the Grand Prix motorcycle racing, World Rally Championship and FIA World Endurance Championship. The premier national auto racing event is the British Touring Car Championship (BTCC). Motorcycle road racing has a long tradition with races such as the Isle of Man TT and the North West 200. -Golf is the sixth-most popular sport, by participation, in the UK. Although The Royal and Ancient Golf Club of St Andrews in Scotland is the sport's home course,[480] the world's oldest golf course is actually Musselburgh Links' Old Golf Course.[481] -Snooker is one of the UK's popular sporting exports, with the world championships held annually in Sheffield.[482] The modern game of lawn tennis first originated in the city of Birmingham between 1859 and 1865.[483] The Championships, Wimbledon are international tennis events held in Wimbledon in south London every summer and are regarded as the most prestigious event of the global tennis calendar. In Northern Ireland Gaelic football and hurling are popular team sports, both in terms of participation and spectating, and Irish expatriates in the UK and the US also play them.[484] Shinty (or camanachd) is popular in the Scottish Highlands.[485] -Symbols -Main article: Symbols of the United Kingdom, the Channel Islands and the Isle of Man - -The Statue of Britannia in Plymouth. Britannia is a national personification of the UK. -The flag of the United Kingdom is the Union Flag (also referred to as the Union Jack). It was created in 1606 by the superimposition of the Flag of England on the Flag of Scotland and updated in 1801 with the addition of Saint Patrick's Flag. Wales is not represented in the Union Flag, as Wales had been conquered and annexed to England prior to the formation of the United Kingdom. The possibility of redesigning the Union Flag to include representation of Wales has not been completely ruled out.[486] The national anthem of the United Kingdom is "God Save the King", with "King" replaced with "Queen" in the lyrics whenever the monarch is a woman. -Britannia is a national personification of the United Kingdom, originating from Roman Britain.[487] Britannia is symbolised as a young woman with brown or golden hair, wearing a Corinthian helmet and white robes. She holds Poseidon's three-pronged trident and a shield, bearing the Union Flag. Sometimes she is depicted as riding on the back of a lion. Since the height of the British Empire in the late 19th century, Britannia has often been associated with British maritime dominance, as in the patriotic song "Rule, Britannia!". Up until 2008, the lion symbol was depicted behind Britannia on the British fifty pence coin and on the back of the British ten pence coin. It is also used as a symbol on the non-ceremonial flag of the British Army. The bulldog is sometimes used as a symbol of the United Kingdom and has been associated with Winston Churchill's defiance of Nazi Germany.[488] -See also -Outline of the United Kingdom - United Kingdom – Wikipedia book -Walking in the United Kingdom -Flag of the United Kingdom.svgUnited Kingdom portal Flag of Europe.svgEuropean Union portal Europe green light.pngEurope portal -Notes -Jump up ^ The Royal coat of arms used in Scotland: - Royal Coat of Arms of the United Kingdom (Scotland).svg -Jump up ^ There is no authorised version of the national anthem as the words are a matter of tradition; only the first verse is usually sung.[1] No law was passed making "God Save the Queen" the official anthem. In the English tradition, such laws are not necessary; proclamation and usage are sufficient to make it the national anthem. "God Save the Queen" also serves as the Royal anthem for several other countries, namely certain Commonwealth realms. -Jump up ^ Under the Council of Europe's European Charter for Regional or Minority Languages, Scots, Ulster-Scots, Welsh, Cornish, Irish and Scottish Gaelic, are officially recognised as regional or minority languages by the British government for the purposes of the Charter. See also Languages of the United Kingdom.[2] -Jump up ^ Although Northern Ireland is the only part of the UK that shares a land border with another state, two of its Overseas Territories also share land borders with other states. Gibraltar shares a border with Spain, while the Sovereign Base Areas of Akrotiri and Dhekelia share borders with the Republic of Cyprus, Turkish Republic of Northern Cyprus and UN buffer zone separating the two Cypriot polities. -Jump up ^ The Anglo-Irish Treaty was signed on 6 December 1921 to resolve the Irish War of Independence. Effective one year later, it established the Irish Free State as a separate dominion within the Commonwealth.

"Unfinished Business: The Scotland Act 1998". The Modern Law Review 62 (2): 241–60 [p. 249]. doi:10.1111/1468-2230.00203. The UK Parliament is sovereign and the Scottish Parliament is subordinate. The White Paper had indicated that this was to be the approach taken in the legislation. The Scottish Parliament is not to be seen as a reflection of the settled will of the people of Scotland or of popular sovereignty but as a reflection of its subordination to a higher legal authority. Following the logic of this argument, the power of the Scottish Parliament to legislate can be withdrawn or overridden... -Jump up ^ Elliot, M. (2004). "United Kingdom: Parliamentary sovereignty under pressure". International Journal of Constitutional Law 2 (3): 545–627 [pp. 553–554]. doi:10.1093/icon/2.3.545. Notwithstanding substantial differences among the schemes, an important common factor is that the U.K. Parliament has not renounced legislative sovereignty in relation to the three nations concerned. For example, the Scottish Parliament is empowered to enact primary legislation on all matters, save those in relation to which competence is explicitly denied ... but this power to legislate on what may be termed "devolved matters" is concurrent with the Westminster Parliament's general power to legislate for Scotland on any matter at all, including devolved matters ... In theory, therefore, Westminster may legislate on Scottish devolved matters whenever it chooses... -Jump up ^ Walker, G. (2010). "Scotland, Northern Ireland, and Devolution, 1945–1979".

Publius 36 (1): 19–35 [p. 29]. doi:10.1093/publius/pjj011. The British parliament has the power to abolish the Scottish parliament and the Welsh assembly by a simple majority vote in both houses, but since both were sanctioned by referenda, it would be politically difficult to abolish them without the sanction of a further vote by the people. In this way several of the constitutional measures introduced by the Blair government appear to be entrenched and not subject to a simple exercise of parliamentary sovereignty at Westminster. -Jump up ^ Meehan, E. (1999). "The Belfast Agreement—Its Distinctiveness and Points of Cross-Fertilization in the UK's Devolution Programme". Parliamentary Affairs 52 (1): 19–31 [p. 23]. doi:10.1093/pa/52.1.19. [T]he distinctive involvement of two governments in the Northern Irish problem means that Northern Ireland's new arrangements rest upon an intergovernmental agreement. If this can be equated with a treaty, it could be argued that the forthcoming distribution of power between Westminster and Belfast has similarities with divisions specified in the written constitutions of federal states... Although the Agreement makes the general proviso that Westminster's 'powers to make legislation for Northern Ireland' remains 'unaffected', without an explicit categorical reference to reserved matters, it may be more difficult than in Scotland or Wales for devolved powers to be repatriated. The retraction of devolved powers would not merely entail consultation in Northern Ireland backed implicitly by the absolute power of parliamentary sovereignty but also the renegotiation of an intergovernmental agreement. -Jump up ^ "The Treaty (act) of the Union of Parliament 1706".

The organization officially commenced on 1 January 1995 under the Marrakech Agreement, replacing the General Agreement on Tariffs and Trade (GATT), which commenced in 1948.[5] The organization deals with regulation of trade between participating countries by providing a framework for negotiating and formalizing trade agreements and a dispute resolution process aimed at enforcing participants' adherence to WTO agreements, which are signed by representatives of member governments[6]:fol.9–10 and ratified by their parliaments.[7] Most of the issues that the WTO focuses on derive from previous trade negotiations, especially from the Uruguay Round (1986–1994). -The organization is attempting to complete negotiations on the Doha Development Round, which was launched in 2001 with an explicit focus on addressing the needs of developing countries. As of June 2012, the future of the Doha Round remained uncertain: the work programme lists 21 subjects in which the original deadline of 1 January 2005 was missed, and the round is still incomplete.[8] The conflict between free trade on industrial goods and services but retention of protectionism on farm subsidies to domestic agricultural sector (requested by developed countries) and the substantiation of the international liberalization of fair trade on agricultural products (requested by developing countries) remain the major obstacles. These points of contention have hindered any progress to launch new WTO negotiations beyond the Doha Development Round. As a result of this impasse, there has been an increasing number of bilateral free trade agreements signed.[9] As of July 2012, there were various negotiation groups in the WTO system for the current agricultural trade negotiation which is in the condition of stalemate.[10] -WTO's current Director-General is Roberto Azevêdo,[11][12] who leads a staff of over 600 people in Geneva, Switzerland.[13] A trade facilitation agreement known as the Bali Package was reached by all members on 7 December 2013, the first comprehensive agreement in the organization's history.[14][15] -Contents [hide] -1 History -1.1 GATT rounds of negotiations -1.1.1 From Geneva to Tokyo -1.1.2 Uruguay Round -1.2 Ministerial conferences -1.3 Doha Round (Doha Agenda) -2 Functions -3 Principles of the trading system -4 Organizational structure -5 Decision-making -6 Dispute settlement -7 Accession and membership -7.1 Accession process -7.2 Members and observers -8 Agreements -9 Office of director-general -9.1 List of directors-general -10 See also -11 Notes and references -12 External links -History - -The economists Harry White (left) and John Maynard Keynes at the Bretton Woods Conference. Both had been strong advocates of a central-controlled international trade environment and recommended the establishment of three institutions: the IMF (for fiscal and monetary issues); the World Bank (for financial and structural issues); and the ITO (for international economic cooperation).[16] -The WTO's predecessor, the General Agreement on Tariffs and Trade (GATT), was established after World War II in the wake of other new multilateral institutions dedicated to international economic cooperation – notably the Bretton Woods institutions known as the World Bank and the International Monetary Fund. A comparable international institution for trade, named the International Trade Organization was successfully negotiated. The ITO was to be a United Nations specialized agency and would address not only trade barriers but other issues indirectly related to trade, including employment, investment, restrictive business practices, and commodity agreements. But the ITO treaty was not approved by the U.S. and a few other signatories and never went into effect.[17][18][19] -In the absence of an international organization for trade, the GATT would over the years "transform itself" into a de facto international organization.[20] -GATT rounds of negotiations -See also: General Agreement on Tariffs and Trade -The GATT was the only multilateral instrument governing international trade from 1946 until the WTO was established on 1 January 1995.[21] Despite attempts in the mid-1950s and 1960s to create some form of institutional mechanism for international trade, the GATT continued to operate for almost half a century as a semi-institutionalized multilateral treaty regime on a provisional basis.[22] -From Geneva to Tokyo -Seven rounds of negotiations occurred under GATT. The first real GATT trade rounds concentrated on further reducing tariffs. Then, the Kennedy Round in the mid-sixties brought about a GATT anti-dumping Agreement and a section on development. The Tokyo Round during the seventies was the first major attempt to tackle trade barriers that do not take the form of tariffs, and to improve the system, adopting a series of agreements on non-tariff barriers, which in some cases interpreted existing GATT rules, and in others broke entirely new ground. Because these plurilateral agreements were not accepted by the full GATT membership, they were often informally called "codes". Several of these codes were amended in the Uruguay Round, and turned into multilateral commitments accepted by all WTO members. Only four remained plurilateral (those on government procurement, bovine meat, civil aircraft and dairy products), but in 1997 WTO members agreed to terminate the bovine meat and dairy agreements, leaving only two.[21] -Uruguay Round -Main article: Uruguay Round - -During the Doha Round, the US government blamed Brazil and India for being inflexible and the EU for impeding agricultural imports.[23] The then-President of Brazil, Luiz Inácio Lula da Silva (above right), responded to the criticisms by arguing that progress would only be achieved if the richest countries (especially the US and countries in the EU) made deeper cuts in agricultural subsidies and further opened their markets for agricultural goods.[24] -Well before GATT's 40th anniversary, its members concluded that the GATT system was straining to adapt to a new globalizing world economy.[25][26] In response to the problems identified in the 1982 Ministerial Declaration (structural deficiencies, spill-over impacts of certain countries' policies on world trade GATT could not manage etc.), the eighth GATT round – known as the Uruguay Round – was launched in September 1986, in Punta del Este, Uruguay.[25] -It was the biggest negotiating mandate on trade ever agreed: the talks were going to extend the trading system into several new areas, notably trade in services and intellectual property, and to reform trade in the sensitive sectors of agriculture and textiles; all the original GATT articles were up for review.[26] The Final Act concluding the Uruguay Round and officially establishing the WTO regime was signed 15 April 1994, during the ministerial meeting at Marrakesh, Morocco, and hence is known as the Marrakesh Agreement.[27] -The GATT still exists as the WTO's umbrella treaty for trade in goods, updated as a result of the Uruguay Round negotiations (a distinction is made between GATT 1994, the updated parts of GATT, and GATT 1947, the original agreement which is still the heart of GATT 1994).[25] GATT 1994 is not however the only legally binding agreement included via the Final Act at Marrakesh; a long list of about 60 agreements, annexes, decisions and understandings was adopted. The agreements fall into a structure with six main parts: -The Agreement Establishing the WTO -Goods and investment – the Multilateral Agreements on Trade in Goods including the GATT 1994 and the Trade Related Investment Measures (TRIMS) -Services — the General Agreement on Trade in Services -Intellectual property – the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) -Dispute settlement (DSU) -Reviews of governments' trade policies (TPRM)[28] -In terms of the WTO's principle relating to tariff "ceiling-binding" (No. 3), the Uruguay Round has been successful in increasing binding commitments by both developed and developing countries, as may be seen in the percentages of tariffs bound before and after the 1986–1994 talks.[29] -Ministerial conferences - -The World Trade Organization Ministerial Conference of 1998, in the Palace of Nations (Geneva, Switzerland). -The highest decision-making body of the WTO is the Ministerial Conference, which usually meets every two years. It brings together all members of the WTO, all of which are countries or customs unions. The Ministerial Conference can take decisions on all matters under any of the multilateral trade agreements. The inaugural ministerial conference was held in Singapore in 1996. Disagreements between largely developed and developing economies emerged during this conference over four issues initiated by this conference, which led to them being collectively referred to as the "Singapore issues". The second ministerial conference was held in Geneva in Switzerland. The third conference in Seattle, Washington ended in failure, with massive demonstrations and police and National Guard crowd-control efforts drawing worldwide attention. The fourth ministerial conference was held in Doha in the Persian Gulf nation of Qatar. The Doha Development Round was launched at the conference. The conference also approved the joining of China, which became the 143rd member to join. The fifth ministerial conference was held in Cancún, Mexico, aiming at forging agreement on the Doha round. An alliance of 22 southern states, the G20 developing nations (led by India, China,[30] Brazil, ASEAN led by the Philippines), resisted demands from the North for agreements on the so-called "Singapore issues" and called for an end to agricultural subsidies within the EU and the US. The talks broke down without progress. -The sixth WTO ministerial conference was held in Hong Kong from 13–18 December 2005. It was considered vital if the four-year-old Doha Development Round negotiations were to move forward sufficiently to conclude the round in 2006. In this meeting, countries agreed to phase out all their agricultural export subsidies by the end of 2013, and terminate any cotton export subsidies by the end of 2006. Further concessions to developing countries included an agreement to introduce duty-free, tariff-free access for goods from the Least Developed Countries, following the Everything but Arms initiative of the European Union — but with up to 3% of tariff lines exempted. Other major issues were left for further negotiation to be completed by the end of 2010. The WTO General Council, on 26 May 2009, agreed to hold a seventh WTO ministerial conference session in Geneva from 30 November-3 December 2009. A statement by chairman Amb. Mario Matus acknowledged that the prime purpose was to remedy a breach of protocol requiring two-yearly "regular" meetings, which had lapsed with the Doha Round failure in 2005, and that the "scaled-down" meeting would not be a negotiating session, but "emphasis will be on transparency and open discussion rather than on small group processes and informal negotiating structures". The general theme for discussion was "The WTO, the Multilateral Trading System and the Current Global Economic Environment"[31] -Doha Round (Doha Agenda) -Main article: Doha Development Round - -The Doha Development Round started in 2001 is at an impasse. -The WTO launched the current round of negotiations, the Doha Development Round, at the fourth ministerial conference in Doha, Qatar in November 2001. This was to be an ambitious effort to make globalization more inclusive and help the world's poor, particularly by slashing barriers and subsidies in farming.[32] The initial agenda comprised both further trade liberalization and new rule-making, underpinned by commitments to strengthen substantial assistance to developing countries.[33] -The negotiations have been highly contentious. Disagreements still continue over several key areas including agriculture subsidies, which emerged as critical in July 2006.[34] According to a European Union statement, "The 2008 Ministerial meeting broke down over a disagreement between exporters of agricultural bulk commodities and countries with large numbers of subsistence farmers on the precise terms of a 'special safeguard measure' to protect farmers from surges in imports."[35] The position of the European Commission is that "The successful conclusion of the Doha negotiations would confirm the central role of multilateral liberalisation and rule-making. It would confirm the WTO as a powerful shield against protectionist backsliding."[33] An impasse remains and, as of August 2013, agreement has not been reached, despite intense negotiations at several ministerial conferences and at other sessions. On 27 March 2013, the chairman of agriculture talks announced "a proposal to loosen price support disciplines for developing countries’ public stocks and domestic food aid." He added: “...we are not yet close to agreement—in fact, the substantive discussion of the proposal is only beginning.”[36] -[show]v · t · eGATT and WTO trade rounds[37] -Functions -Among the various functions of the WTO, these are regarded by analysts as the most important: -It oversees the implementation, administration and operation of the covered agreements.[38][39] -It provides a forum for negotiations and for settling disputes.[40][41] -Additionally, it is the WTO's duty to review and propagate the national trade policies, and to ensure the coherence and transparency of trade policies through surveillance in global economic policy-making.[39][41] Another priority of the WTO is the assistance of developing, least-developed and low-income countries in transition to adjust to WTO rules and disciplines through technical cooperation and training.[42] -(i) The WTO shall facilitate the implementation, administration and operation and further the objec­tives of this Agreement and of the Multilateral Trade Agreements, and shall also provide the frame work for the implementation, administration and operation of the multilateral Trade Agreements. -(ii) The WTO shall provide the forum for negotiations among its members concerning their multilateral trade relations in matters dealt with under the Agreement in the Annexes to this Agreement. -(iii) The WTO shall administer the Understanding on Rules and Procedures Governing the Settlement of Disputes. -(iv) The WTO shall administer Trade Policy Review Mechanism. -(v) With a view to achieving greater coherence in global economic policy making, the WTO shall cooperate, as appropriate, with the international Monetary Fund (IMF) and with the International Bank for Reconstruction and Development (IBRD) and its affiliated agencies. [43] -The above five listings are the additional functions of the World Trade Organization. As globalization proceeds in today's society, the necessity of an International Organization to manage the trading systems has been of vital importance. As the trade volume increases, issues such as protectionism, trade barriers, subsidies, violation of intellectual property arise due to the differences in the trading rules of every nation. The World Trade Organization serves as the mediator between the nations when such problems arise. WTO could be referred to as the product of globalization and also as one of the most important organizations in today's globalized society. -The WTO is also a center of economic research and analysis: regular assessments of the global trade picture in its annual publications and research reports on specific topics are produced by the organization.[44] Finally, the WTO cooperates closely with the two other components of the Bretton Woods system, the IMF and the World Bank.[40] -Principles of the trading system -The WTO establishes a framework for trade policies; it does not define or specify outcomes. That is, it is concerned with setting the rules of the trade policy games.[45] Five principles are of particular importance in understanding both the pre-1994 GATT and the WTO: -Non-discrimination. It has two major components: the most favoured nation (MFN) rule, and the national treatment policy. Both are embedded in the main WTO rules on goods, services, and intellectual property, but their precise scope and nature differ across these areas. The MFN rule requires that a WTO member must apply the same conditions on all trade with other WTO members, i.e. a WTO member has to grant the most favorable conditions under which it allows trade in a certain product type to all other WTO members.[45] "Grant someone a special favour and you have to do the same for all other WTO members."[29] National treatment means that imported goods should be treated no less favorably than domestically produced goods (at least after the foreign goods have entered the market) and was introduced to tackle non-tariff barriers to trade (e.g. technical standards, security standards et al. discriminating against imported goods).[45] -Reciprocity. It reflects both a desire to limit the scope of free-riding that may arise because of the MFN rule, and a desire to obtain better access to foreign markets. A related point is that for a nation to negotiate, it is necessary that the gain from doing so be greater than the gain available from unilateral liberalization; reciprocal concessions intend to ensure that such gains will materialise.[46] -Binding and enforceable commitments. The tariff commitments made by WTO members in a multilateral trade negotiation and on accession are enumerated in a schedule (list) of concessions. These schedules establish "ceiling bindings": a country can change its bindings, but only after negotiating with its trading partners, which could mean compensating them for loss of trade. If satisfaction is not obtained, the complaining country may invoke the WTO dispute settlement procedures.[29][46] -Transparency. The WTO members are required to publish their trade regulations, to maintain institutions allowing for the review of administrative decisions affecting trade, to respond to requests for information by other members, and to notify changes in trade policies to the WTO. These internal transparency requirements are supplemented and facilitated by periodic country-specific reports (trade policy reviews) through the Trade Policy Review Mechanism (TPRM).[47] The WTO system tries also to improve predictability and stability, discouraging the use of quotas and other measures used to set limits on quantities of imports.[29] -Safety valves. In specific circumstances, governments are able to restrict trade. The WTO's agreements permit members to take measures to protect not only the environment but also public health, animal health and plant health.[48] -There are three types of provision in this direction: -articles allowing for the use of trade measures to attain non-economic objectives; -articles aimed at ensuring "fair competition"; members must not use environmental protection measures as a means of disguising protectionist policies.[48] -provisions permitting intervention in trade for economic reasons.[47] -Exceptions to the MFN principle also allow for preferential treatment of developing countries, regional free trade areas and customs unions.[6]:fol.93 -Organizational structure -The General Council has the following subsidiary bodies which oversee committees in different areas: -Council for Trade in Goods -There are 11 committees under the jurisdiction of the Goods Council each with a specific task. All members of the WTO participate in the committees. The Textiles Monitoring Body is separate from the other committees but still under the jurisdiction of Goods Council. The body has its own chairman and only 10 members. The body also has several groups relating to textiles.[49] -Council for Trade-Related Aspects of Intellectual Property Rights -Information on intellectual property in the WTO, news and official records of the activities of the TRIPS Council, and details of the WTO's work with other international organizations in the field.[50] -Council for Trade in Services -The Council for Trade in Services operates under the guidance of the General Council and is responsible for overseeing the functioning of the General Agreement on Trade in Services (GATS). It is open to all WTO members, and can create subsidiary bodies as required.[51] -Trade Negotiations Committee -The Trade Negotiations Committee (TNC) is the committee that deals with the current trade talks round. The chair is WTO's director-general. As of June 2012 the committee was tasked with the Doha Development Round.[52] -The Service Council has three subsidiary bodies: financial services, domestic regulations, GATS rules and specific commitments.[49] The council has several different committees, working groups, and working parties.[53] There are committees on the following: Trade and Environment; Trade and Development (Subcommittee on Least-Developed Countries); Regional Trade Agreements; Balance of Payments Restrictions; and Budget, Finance and Administration. There are working parties on the following: Accession. There are working groups on the following: Trade, debt and finance; and Trade and technology transfer. -Decision-making -The WTO describes itself as "a rules-based, member-driven organization — all decisions are made by the member governments, and the rules are the outcome of negotiations among members".[54] The WTO Agreement foresees votes where consensus cannot be reached, but the practice of consensus dominates the process of decision-making.[55] -Richard Harold Steinberg (2002) argues that although the WTO's consensus governance model provides law-based initial bargaining, trading rounds close through power-based bargaining favouring Europe and the U.S., and may not lead to Pareto improvement.[56] -Dispute settlement -Main article: Dispute settlement in the WTO -In 1994, the WTO members agreed on the Understanding on Rules and Procedures Governing the Settlement of Disputes (DSU) annexed to the "Final Act" signed in Marrakesh in 1994.[57] Dispute settlement is regarded by the WTO as the central pillar of the multilateral trading system, and as a "unique contribution to the stability of the global economy".[58] WTO members have agreed that, if they believe fellow-members are violating trade rules, they will use the multilateral system of settling disputes instead of taking action unilaterally.[59] -The operation of the WTO dispute settlement process involves the DSB panels, the Appellate Body, the WTO Secretariat, arbitrators, independent experts and several specialized institutions.[60] Bodies involved in the dispute settlement process, World Trade Organization. -Accession and membership -Main article: World Trade Organization accession and membership -The process of becoming a WTO member is unique to each applicant country, and the terms of accession are dependent upon the country's stage of economic development and current trade regime.[61] The process takes about five years, on average, but it can last more if the country is less than fully committed to the process or if political issues interfere. The shortest accession negotiation was that of the Kyrgyz Republic, while the longest was that of Russia, which, having first applied to join GATT in 1993, was approved for membership in December 2011 and became a WTO member on 22 August 2012.[62] The second longest was that of Vanuatu, whose Working Party on the Accession of Vanuatu was established on 11 July 1995. After a final meeting of the Working Party in October 2001, Vanuatu requested more time to consider its accession terms. In 2008, it indicated its interest to resume and conclude its WTO accession. The Working Party on the Accession of Vanuatu was reconvened informally on 4 April 2011 to discuss Vanuatu's future WTO membership. The re-convened Working Party completed its mandate on 2 May 2011. The General Council formally approved the Accession Package of Vanuatu on 26 October 2011. On 24 August 2012, the WTO welcomed Vanuatu as its 157th member.[63] An offer of accession is only given once consensus is reached among interested parties.[64] -Accession process - -WTO accession progress: - Members (including dual-representation with the European Union) - Draft Working Party Report or Factual Summary adopted - Goods and/or Services offers submitted - Memorandum on Foreign Trade Regime (FTR) submitted - Observer, negotiations to start later or no Memorandum on FTR submitted - Frozen procedures or no negotiations in the last 3 years - No official interaction with the WTO -A country wishing to accede to the WTO submits an application to the General Council, and has to describe all aspects of its trade and economic policies that have a bearing on WTO agreements.[65] The application is submitted to the WTO in a memorandum which is examined by a working party open to all interested WTO Members.[66] -After all necessary background information has been acquired, the working party focuses on issues of discrepancy between the WTO rules and the applicant's international and domestic trade policies and laws. The working party determines the terms and conditions of entry into the WTO for the applicant nation, and may consider transitional periods to allow countries some leeway in complying with the WTO rules.[61] -The final phase of accession involves bilateral negotiations between the applicant nation and other working party members regarding the concessions and commitments on tariff levels and market access for goods and services. The new member's commitments are to apply equally to all WTO members under normal non-discrimination rules, even though they are negotiated bilaterally.[65] -When the bilateral talks conclude, the working party sends to the general council or ministerial conference an accession package, which includes a summary of all the working party meetings, the Protocol of Accession (a draft membership treaty), and lists ("schedules") of the member-to-be's commitments. Once the general council or ministerial conference approves of the terms of accession, the applicant's parliament must ratify the Protocol of Accession before it can become a member.[67] Some countries may have faced tougher and a much longer accession process due to challenges during negotiations with other WTO members, such as Vietnam, whose negotiations took more than 11 years before it became official member in January 2007.[68] -Members and observers -The WTO has 160 members and 24 observer governments.[69] In addition to states, the European Union is a member. WTO members do not have to be full sovereign nation-members. Instead, they must be a customs territory with full autonomy in the conduct of their external commercial relations. Thus Hong Kong has been a member since 1995 (as "Hong Kong, China" since 1997) predating the People's Republic of China, which joined in 2001 after 15 years of negotiations. The Republic of China (Taiwan) acceded to the WTO in 2002 as "Separate Customs Territory of Taiwan, Penghu, Kinmen and Matsu" (Chinese Taipei) despite its disputed status.[70] The WTO Secretariat omits the official titles (such as Counselor, First Secretary, Second Secretary and Third Secretary) of the members of Chinese Taipei's Permanent Mission to the WTO, except for the titles of the Permanent Representative and the Deputy Permanent Representative.[71] -As of 2007, WTO member states represented 96.4% of global trade and 96.7% of global GDP.[72] Iran, followed by Algeria, are the economies with the largest GDP and trade outside the WTO, using 2005 data.[73][74] With the exception of the Holy See, observers must start accession negotiations within five years of becoming observers. A number of international intergovernmental organizations have also been granted observer status to WTO bodies.[75] 14 UN member states have no official affiliation with the WTO. -Agreements -Further information: Uruguay Round -The WTO oversees about 60 different agreements which have the status of international legal texts. Member countries must sign and ratify all WTO agreements on accession.[76] A discussion of some of the most important agreements follows. The Agreement on Agriculture came into effect with the establishment of the WTO at the beginning of 1995. The AoA has three central concepts, or "pillars": domestic support, market access and export subsidies. The General Agreement on Trade in Services was created to extend the multilateral trading system to service sector, in the same way as the General Agreement on Tariffs and Trade (GATT) provided such a system for merchandise trade. The agreement entered into force in January 1995. The Agreement on Trade-Related Aspects of Intellectual Property Rights sets down minimum standards for many forms of intellectual property (IP) regulation. It was negotiated at the end of the Uruguay Round of the General Agreement on Tariffs and Trade (GATT) in 1994.[77] -The Agreement on the Application of Sanitary and Phytosanitary Measures—also known as the SPS Agreement—was negotiated during the Uruguay Round of GATT, and entered into force with the establishment of the WTO at the beginning of 1995. Under the SPS agreement, the WTO sets constraints on members' policies relating to food safety (bacterial contaminants, pesticides, inspection and labelling) as well as animal and plant health (imported pests and diseases). The Agreement on Technical Barriers to Trade is an international treaty of the World Trade Organization. It was negotiated during the Uruguay Round of the General Agreement on Tariffs and Trade, and entered into force with the establishment of the WTO at the end of 1994. The object ensures that technical negotiations and standards, as well as testing and certification procedures, do not create unnecessary obstacles to trade".[78] The Agreement on Customs Valuation, formally known as the Agreement on Implementation of Article VII of GATT, prescribes methods of customs valuation that Members are to follow. Chiefly, it adopts the "transaction value" approach. -In December 2013, the biggest agreement within the WTO was signed and known as the Bali Package.[79] -Office of director-general - -The headquarters of the World Trade Organization, in Geneva, Switzerland. -The procedures for the appointment of the WTO director-general were published in January 2003.[80] Additionally, there are four deputy directors-general. As of 1 October 2013, under director-general Roberto Azevêdo, the four deputy directors-general are Yi Xiaozhun of China, Karl-Ernst Brauner of Germany, Yonov Frederick Agah of Nigeria and David Shark of the United States.[81] -List of directors-general -Source: Official website[82] -Brazil Roberto Azevedo, 2013– -France Pascal Lamy, 2005–2013 -Thailand Supachai Panitchpakdi, 2002–2005 -New Zealand Mike Moore, 1999–2002 -Italy Renato Ruggiero, 1995–1999 -Republic of Ireland Peter Sutherland, 1995 -(Heads of the precursor organization, GATT): -Republic of Ireland Peter Sutherland, 1993–1995 -Switzerland Arthur Dunkel, 1980–1993 -Switzerland Olivier Long, 1968–1980 -United Kingdom Eric Wyndham White, 1948–1968 -See also -Agreement on Trade Related Investment Measures (TRIMS) -Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) -Aide-mémoire non-paper -Anti-globalization movement -Criticism of the World Trade Organization -Foreign Affiliate Trade Statistics -Global administrative law -Globality -Information Technology Agreement -International Trade Centre -Labour Standards in the World Trade Organisation -List of member states of the World Trade Organization -North American Free Trade Agreement (NAFTA) -Subsidy -Swiss Formula -Trade bloc -Washington Consensus -World Trade Report -World Trade Organization Ministerial Conference of 1999 protest activity -China and the World Trade Organization -Notes and references -Jump up ^ Members and Observers at WTO official website -Jump up ^ Languages, Documentation and Information Management Division at WTO official site -Jump up ^ "WTO Secretariat budget for 2011".

It is represented as a single file on -your disk and represents a consistent snapshot of your data. - -To open your database, simply use the `bolt.Open()` function: - -```go -package main - -import ( - "log" - - "github.com/boltdb/bolt" -) - -func main() { - // Open the my.db data file in your current directory. - // It will be created if it doesn't exist. - db, err := bolt.Open("my.db", 0600, nil) - if err != nil { - log.Fatal(err) - } - defer db.Close() - - ... -} -``` - -Please note that Bolt obtains a file lock on the data file so multiple processes -cannot open the same database at the same time. Opening an already open Bolt -database will cause it to hang until the other process closes it. To prevent -an indefinite wait you can pass a timeout option to the `Open()` function: - -```go -db, err := bolt.Open("my.db", 0600, &bolt.Options{Timeout: 1 * time.Second}) -``` - - -### Transactions - -Bolt allows only one read-write transaction at a time but allows as many -read-only transactions as you want at a time. Each transaction has a consistent -view of the data as it existed when the transaction started. - -Individual transactions and all objects created from them (e.g. buckets, keys) -are not thread safe. To work with data in multiple goroutines you must start -a transaction for each one or use locking to ensure only one goroutine accesses -a transaction at a time. Creating transaction from the `DB` is thread safe. - -Read-only transactions and read-write transactions should not depend on one -another and generally shouldn't be opened simultaneously in the same goroutine. -This can cause a deadlock as the read-write transaction needs to periodically -re-map the data file but it cannot do so while a read-only transaction is open. - - -#### Read-write transactions - -To start a read-write transaction, you can use the `DB.Update()` function: - -```go -err := db.Update(func(tx *bolt.Tx) error { - ... - return nil -}) -``` - -Inside the closure, you have a consistent view of the database. You commit the -transaction by returning `nil` at the end. You can also rollback the transaction -at any point by returning an error. All database operations are allowed inside -a read-write transaction. - -Always check the return error as it will report any disk failures that can cause -your transaction to not complete. If you return an error within your closure -it will be passed through. - - -#### Read-only transactions - -To start a read-only transaction, you can use the `DB.View()` function: - -```go -err := db.View(func(tx *bolt.Tx) error { - ... - return nil -}) -``` - -You also get a consistent view of the database within this closure, however, -no mutating operations are allowed within a read-only transaction. You can only -retrieve buckets, retrieve values, and copy the database within a read-only -transaction. - - -#### Batch read-write transactions - -Each `DB.Update()` waits for disk to commit the writes. This overhead -can be minimized by combining multiple updates with the `DB.Batch()` -function: - -```go -err := db.Batch(func(tx *bolt.Tx) error { - ... - return nil -}) -``` - -Concurrent Batch calls are opportunistically combined into larger -transactions. Batch is only useful when there are multiple goroutines -calling it. - -The trade-off is that `Batch` can call the given -function multiple times, if parts of the transaction fail. The -function must be idempotent and side effects must take effect only -after a successful return from `DB.Batch()`. - -For example: don't display messages from inside the function, instead -set variables in the enclosing scope: - -```go -var id uint64 -err := db.Batch(func(tx *bolt.Tx) error { - // Find last key in bucket, decode as bigendian uint64, increment - // by one, encode back to []byte, and add new key. - ... - id = newValue - return nil -}) -if err != nil { - return ... -} -fmt.Println("Allocated ID %d", id) -``` - - -#### Managing transactions manually - -The `DB.View()` and `DB.Update()` functions are wrappers around the `DB.Begin()` -function. These helper functions will start the transaction, execute a function, -and then safely close your transaction if an error is returned. This is the -recommended way to use Bolt transactions. - -However, sometimes you may want to manually start and end your transactions. -You can use the `DB.Begin()` function directly but **please** be sure to close -the transaction. - -```go -// Start a writable transaction. -tx, err := db.Begin(true) -if err != nil { - return err -} -defer tx.Rollback() - -// Use the transaction... -_, err := tx.CreateBucket([]byte("MyBucket")) -if err != nil { - return err -} - -// Commit the transaction and check for error. -if err := tx.Commit(); err != nil { - return err -} -``` - -The first argument to `DB.Begin()` is a boolean stating if the transaction -should be writable. - - -### Using buckets - -Buckets are collections of key/value pairs within the database. All keys in a -bucket must be unique. You can create a bucket using the `DB.CreateBucket()` -function: - -```go -db.Update(func(tx *bolt.Tx) error { - b, err := tx.CreateBucket([]byte("MyBucket")) - if err != nil { - return fmt.Errorf("create bucket: %s", err) - } - return nil -}) -``` - -You can also create a bucket only if it doesn't exist by using the -`Tx.CreateBucketIfNotExists()` function. It's a common pattern to call this -function for all your top-level buckets after you open your database so you can -guarantee that they exist for future transactions. - -To delete a bucket, simply call the `Tx.DeleteBucket()` function. - - -### Using key/value pairs - -To save a key/value pair to a bucket, use the `Bucket.Put()` function: - -```go -db.Update(func(tx *bolt.Tx) error { - b := tx.Bucket([]byte("MyBucket")) - err := b.Put([]byte("answer"), []byte("42")) - return err -}) -``` - -This will set the value of the `"answer"` key to `"42"` in the `MyBucket` -bucket. To retrieve this value, we can use the `Bucket.Get()` function: - -```go -db.View(func(tx *bolt.Tx) error { - b := tx.Bucket([]byte("MyBucket")) - v := b.Get([]byte("answer")) - fmt.Printf("The answer is: %s\n", v) - return nil -}) -``` - -The `Get()` function does not return an error because its operation is -guaranteed to work (unless there is some kind of system failure). If the key -exists then it will return its byte slice value. If it doesn't exist then it -will return `nil`. It's important to note that you can have a zero-length value -set to a key which is different than the key not existing. - -Use the `Bucket.Delete()` function to delete a key from the bucket. - -Please note that values returned from `Get()` are only valid while the -transaction is open. If you need to use a value outside of the transaction -then you must use `copy()` to copy it to another byte slice. - - -### Autoincrementing integer for the bucket -By using the `NextSequence()` function, you can let Bolt determine a sequence -which can be used as the unique identifier for your key/value pairs. See the -example below. - -```go -// CreateUser saves u to the store. The new user ID is set on u once the data is persisted. -func (s *Store) CreateUser(u *User) error { - return s.db.Update(func(tx *bolt.Tx) error { - // Retrieve the users bucket. - // This should be created when the DB is first opened. - b := tx.Bucket([]byte("users")) - - // Generate ID for the user. - // This returns an error only if the Tx is closed or not writeable. - // That can't happen in an Update() call so I ignore the error check. - id, _ := b.NextSequence() - u.ID = int(id) - - // Marshal user data into bytes. - buf, err := json.Marshal(u) - if err != nil { - return err - } - - // Persist bytes to users bucket. - return b.Put(itob(u.ID), buf) - }) -} - -// itob returns an 8-byte big endian representation of v. -func itob(v int) []byte { - b := make([]byte, 8) - binary.BigEndian.PutUint64(b, uint64(v)) - return b -} - -type User struct { - ID int - ... -} -``` - -### Iterating over keys - -Bolt stores its keys in byte-sorted order within a bucket. This makes sequential -iteration over these keys extremely fast. To iterate over keys we'll use a -`Cursor`: - -```go -db.View(func(tx *bolt.Tx) error { - // Assume bucket exists and has keys - b := tx.Bucket([]byte("MyBucket")) - - c := b.Cursor() - - for k, v := c.First(); k != nil; k, v = c.Next() { - fmt.Printf("key=%s, value=%s\n", k, v) - } - - return nil -}) -``` - -The cursor allows you to move to a specific point in the list of keys and move -forward or backward through the keys one at a time. - -The following functions are available on the cursor: - -``` -First() Move to the first key. -Last() Move to the last key. -Seek() Move to a specific key. -Next() Move to the next key. -Prev() Move to the previous key. -``` - -Each of those functions has a return signature of `(key []byte, value []byte)`. -When you have iterated to the end of the cursor then `Next()` will return a -`nil` key. You must seek to a position using `First()`, `Last()`, or `Seek()` -before calling `Next()` or `Prev()`. If you do not seek to a position then -these functions will return a `nil` key. - -During iteration, if the key is non-`nil` but the value is `nil`, that means -the key refers to a bucket rather than a value. Use `Bucket.Bucket()` to -access the sub-bucket. - - -#### Prefix scans - -To iterate over a key prefix, you can combine `Seek()` and `bytes.HasPrefix()`: - -```go -db.View(func(tx *bolt.Tx) error { - // Assume bucket exists and has keys - c := tx.Bucket([]byte("MyBucket")).Cursor() - - prefix := []byte("1234") - for k, v := c.Seek(prefix); k != nil && bytes.HasPrefix(k, prefix); k, v = c.Next() { - fmt.Printf("key=%s, value=%s\n", k, v) - } - - return nil -}) -``` - -#### Range scans - -Another common use case is scanning over a range such as a time range. If you -use a sortable time encoding such as RFC3339 then you can query a specific -date range like this: - -```go -db.View(func(tx *bolt.Tx) error { - // Assume our events bucket exists and has RFC3339 encoded time keys. - c := tx.Bucket([]byte("Events")).Cursor() - - // Our time range spans the 90's decade. - min := []byte("1990-01-01T00:00:00Z") - max := []byte("2000-01-01T00:00:00Z") - - // Iterate over the 90's. - for k, v := c.Seek(min); k != nil && bytes.Compare(k, max) <= 0; k, v = c.Next() { - fmt.Printf("%s: %s\n", k, v) - } - - return nil -}) -``` - -Note that, while RFC3339 is sortable, the Golang implementation of RFC3339Nano does not use a fixed number of digits after the decimal point and is therefore not sortable. - - -#### ForEach() - -You can also use the function `ForEach()` if you know you'll be iterating over -all the keys in a bucket: - -```go -db.View(func(tx *bolt.Tx) error { - // Assume bucket exists and has keys - b := tx.Bucket([]byte("MyBucket")) - - b.ForEach(func(k, v []byte) error { - fmt.Printf("key=%s, value=%s\n", k, v) - return nil - }) - return nil -}) -``` - -Please note that keys and values in `ForEach()` are only valid while -the transaction is open. If you need to use a key or value outside of -the transaction, you must use `copy()` to copy it to another byte -slice. - -### Nested buckets - -You can also store a bucket in a key to create nested buckets. The API is the -same as the bucket management API on the `DB` object: - -```go -func (*Bucket) CreateBucket(key []byte) (*Bucket, error) -func (*Bucket) CreateBucketIfNotExists(key []byte) (*Bucket, error) -func (*Bucket) DeleteBucket(key []byte) error -``` - -Say you had a multi-tenant application where the root level bucket was the account bucket. Inside of this bucket was a sequence of accounts which themselves are buckets. And inside the sequence bucket you could have many buckets pertaining to the Account itself (Users, Notes, etc) isolating the information into logical groupings. - -```go - -// createUser creates a new user in the given account. -func createUser(accountID int, u *User) error { - // Start the transaction. - tx, err := db.Begin(true) - if err != nil { - return err - } - defer tx.Rollback() - - // Retrieve the root bucket for the account. - // Assume this has already been created when the account was set up. - root := tx.Bucket([]byte(strconv.FormatUint(accountID, 10))) - - // Setup the users bucket. - bkt, err := root.CreateBucketIfNotExists([]byte("USERS")) - if err != nil { - return err - } - - // Generate an ID for the new user. - userID, err := bkt.NextSequence() - if err != nil { - return err - } - u.ID = userID - - // Marshal and save the encoded user. - if buf, err := json.Marshal(u); err != nil { - return err - } else if err := bkt.Put([]byte(strconv.FormatUint(u.ID, 10)), buf); err != nil { - return err - } - - // Commit the transaction. - if err := tx.Commit(); err != nil { - return err - } - - return nil -} - -``` - - - - -### Database backups - -Bolt is a single file so it's easy to backup. You can use the `Tx.WriteTo()` -function to write a consistent view of the database to a writer. If you call -this from a read-only transaction, it will perform a hot backup and not block -your other database reads and writes. - -By default, it will use a regular file handle which will utilize the operating -system's page cache. See the [`Tx`](https://godoc.org/github.com/boltdb/bolt#Tx) -documentation for information about optimizing for larger-than-RAM datasets. - -One common use case is to backup over HTTP so you can use tools like `cURL` to -do database backups: - -```go -func BackupHandleFunc(w http.ResponseWriter, req *http.Request) { - err := db.View(func(tx *bolt.Tx) error { - w.Header().Set("Content-Type", "application/octet-stream") - w.Header().Set("Content-Disposition", `attachment; filename="my.db"`) - w.Header().Set("Content-Length", strconv.Itoa(int(tx.Size()))) - _, err := tx.WriteTo(w) - return err - }) - if err != nil { - http.Error(w, err.Error(), http.StatusInternalServerError) - } -} -``` - -Then you can backup using this command: - -```sh -$ curl http://localhost/backup > my.db -``` - -Or you can open your browser to `http://localhost/backup` and it will download -automatically. - -If you want to backup to another file you can use the `Tx.CopyFile()` helper -function. - - -### Statistics - -The database keeps a running count of many of the internal operations it -performs so you can better understand what's going on. By grabbing a snapshot -of these stats at two points in time we can see what operations were performed -in that time range. - -For example, we could start a goroutine to log stats every 10 seconds: - -```go -go func() { - // Grab the initial stats. - prev := db.Stats() - - for { - // Wait for 10s. - time.Sleep(10 * time.Second) - - // Grab the current stats and diff them. - stats := db.Stats() - diff := stats.Sub(&prev) - - // Encode stats to JSON and print to STDERR. - json.NewEncoder(os.Stderr).Encode(diff) - - // Save stats for the next loop. - prev = stats - } -}() -``` - -It's also useful to pipe these stats to a service such as statsd for monitoring -or to provide an HTTP endpoint that will perform a fixed-length sample. - - -### Read-Only Mode - -Sometimes it is useful to create a shared, read-only Bolt database. To this, -set the `Options.ReadOnly` flag when opening your database. Read-only mode -uses a shared lock to allow multiple processes to read from the database but -it will block any processes from opening the database in read-write mode. - -```go -db, err := bolt.Open("my.db", 0666, &bolt.Options{ReadOnly: true}) -if err != nil { - log.Fatal(err) -} -``` - -### Mobile Use (iOS/Android) - -Bolt is able to run on mobile devices by leveraging the binding feature of the -[gomobile](https://github.com/golang/mobile) tool. Create a struct that will -contain your database logic and a reference to a `*bolt.DB` with a initializing -constructor that takes in a filepath where the database file will be stored. -Neither Android nor iOS require extra permissions or cleanup from using this method. - -```go -func NewBoltDB(filepath string) *BoltDB { - db, err := bolt.Open(filepath+"/demo.db", 0600, nil) - if err != nil { - log.Fatal(err) - } - - return &BoltDB{db} -} - -type BoltDB struct { - db *bolt.DB - ... -} - -func (b *BoltDB) Path() string { - return b.db.Path() -} - -func (b *BoltDB) Close() { - b.db.Close() -} -``` - -Database logic should be defined as methods on this wrapper struct. - -To initialize this struct from the native language (both platforms now sync -their local storage to the cloud. These snippets disable that functionality for the -database file): - -#### Android - -```java -String path; -if (android.os.Build.VERSION.SDK_INT >=android.os.Build.VERSION_CODES.LOLLIPOP){ - path = getNoBackupFilesDir().getAbsolutePath(); -} else{ - path = getFilesDir().getAbsolutePath(); -} -Boltmobiledemo.BoltDB boltDB = Boltmobiledemo.NewBoltDB(path) -``` - -#### iOS - -```objc -- (void)demo { - NSString* path = [NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, - NSUserDomainMask, - YES) objectAtIndex:0]; - GoBoltmobiledemoBoltDB * demo = GoBoltmobiledemoNewBoltDB(path); - [self addSkipBackupAttributeToItemAtPath:demo.path]; - //Some DB Logic would go here - [demo close]; -} - -- (BOOL)addSkipBackupAttributeToItemAtPath:(NSString *) filePathString -{ - NSURL* URL= [NSURL fileURLWithPath: filePathString]; - assert([[NSFileManager defaultManager] fileExistsAtPath: [URL path]]); - - NSError *error = nil; - BOOL success = [URL setResourceValue: [NSNumber numberWithBool: YES] - forKey: NSURLIsExcludedFromBackupKey error: &error]; - if(!success){ - NSLog(@"Error excluding %@ from backup %@", [URL lastPathComponent], error); - } - return success; -} - -``` - -## Resources - -For more information on getting started with Bolt, check out the following articles: - -* [Intro to BoltDB: Painless Performant Persistence](http://npf.io/2014/07/intro-to-boltdb-painless-performant-persistence/) by [Nate Finch](https://github.com/natefinch). -* [Bolt -- an embedded key/value database for Go](https://www.progville.com/go/bolt-embedded-db-golang/) by Progville - - -## Comparison with other databases - -### Postgres, MySQL, & other relational databases - -Relational databases structure data into rows and are only accessible through -the use of SQL. This approach provides flexibility in how you store and query -your data but also incurs overhead in parsing and planning SQL statements. Bolt -accesses all data by a byte slice key. This makes Bolt fast to read and write -data by key but provides no built-in support for joining values together. - -Most relational databases (with the exception of SQLite) are standalone servers -that run separately from your application. This gives your systems -flexibility to connect multiple application servers to a single database -server but also adds overhead in serializing and transporting data over the -network. Bolt runs as a library included in your application so all data access -has to go through your application's process. This brings data closer to your -application but limits multi-process access to the data. - - -### LevelDB, RocksDB - -LevelDB and its derivatives (RocksDB, HyperLevelDB) are similar to Bolt in that -they are libraries bundled into the application, however, their underlying -structure is a log-structured merge-tree (LSM tree). An LSM tree optimizes -random writes by using a write ahead log and multi-tiered, sorted files called -SSTables. Bolt uses a B+tree internally and only a single file. Both approaches -have trade-offs. - -If you require a high random write throughput (>10,000 w/sec) or you need to use -spinning disks then LevelDB could be a good choice. If your application is -read-heavy or does a lot of range scans then Bolt could be a good choice. - -One other important consideration is that LevelDB does not have transactions. -It supports batch writing of key/values pairs and it supports read snapshots -but it will not give you the ability to do a compare-and-swap operation safely. -Bolt supports fully serializable ACID transactions. - - -### LMDB - -Bolt was originally a port of LMDB so it is architecturally similar. Both use -a B+tree, have ACID semantics with fully serializable transactions, and support -lock-free MVCC using a single writer and multiple readers. - -The two projects have somewhat diverged. LMDB heavily focuses on raw performance -while Bolt has focused on simplicity and ease of use. For example, LMDB allows -several unsafe actions such as direct writes for the sake of performance. Bolt -opts to disallow actions which can leave the database in a corrupted state. The -only exception to this in Bolt is `DB.NoSync`. - -There are also a few differences in API. LMDB requires a maximum mmap size when -opening an `mdb_env` whereas Bolt will handle incremental mmap resizing -automatically. LMDB overloads the getter and setter functions with multiple -flags whereas Bolt splits these specialized cases into their own functions. - - -## Caveats & Limitations - -It's important to pick the right tool for the job and Bolt is no exception. -Here are a few things to note when evaluating and using Bolt: - -* Bolt is good for read intensive workloads. Sequential write performance is - also fast but random writes can be slow. You can use `DB.Batch()` or add a - write-ahead log to help mitigate this issue. - -* Bolt uses a B+tree internally so there can be a lot of random page access. - SSDs provide a significant performance boost over spinning disks. - -* Try to avoid long running read transactions. Bolt uses copy-on-write so - old pages cannot be reclaimed while an old transaction is using them. - -* Byte slices returned from Bolt are only valid during a transaction. Once the - transaction has been committed or rolled back then the memory they point to - can be reused by a new page or can be unmapped from virtual memory and you'll - see an `unexpected fault address` panic when accessing it. - -* Bolt uses an exclusive write lock on the database file so it cannot be - shared by multiple processes. - -* Be careful when using `Bucket.FillPercent`. Setting a high fill percent for - buckets that have random inserts will cause your database to have very poor - page utilization. - -* Use larger buckets in general. Smaller buckets causes poor page utilization - once they become larger than the page size (typically 4KB). - -* Bulk loading a lot of random writes into a new bucket can be slow as the - page will not split until the transaction is committed. Randomly inserting - more than 100,000 key/value pairs into a single new bucket in a single - transaction is not advised. - -* Bolt uses a memory-mapped file so the underlying operating system handles the - caching of the data. Typically, the OS will cache as much of the file as it - can in memory and will release memory as needed to other processes. This means - that Bolt can show very high memory usage when working with large databases. - However, this is expected and the OS will release memory as needed. Bolt can - handle databases much larger than the available physical RAM, provided its - memory-map fits in the process virtual address space. It may be problematic - on 32-bits systems. - -* The data structures in the Bolt database are memory mapped so the data file - will be endian specific. This means that you cannot copy a Bolt file from a - little endian machine to a big endian machine and have it work. For most - users this is not a concern since most modern CPUs are little endian. - -* Because of the way pages are laid out on disk, Bolt cannot truncate data files - and return free pages back to the disk. Instead, Bolt maintains a free list - of unused pages within its data file. These free pages can be reused by later - transactions. This works well for many use cases as databases generally tend - to grow. However, it's important to note that deleting large chunks of data - will not allow you to reclaim that space on disk. - - For more information on page allocation, [see this comment][page-allocation]. - -[page-allocation]: https://github.com/boltdb/bolt/issues/308#issuecomment-74811638 - - -## Reading the Source - -Bolt is a relatively small code base (<3KLOC) for an embedded, serializable, -transactional key/value database so it can be a good starting point for people -interested in how databases work. - -The best places to start are the main entry points into Bolt: - -- `Open()` - Initializes the reference to the database. It's responsible for - creating the database if it doesn't exist, obtaining an exclusive lock on the - file, reading the meta pages, & memory-mapping the file. - -- `DB.Begin()` - Starts a read-only or read-write transaction depending on the - value of the `writable` argument. This requires briefly obtaining the "meta" - lock to keep track of open transactions. Only one read-write transaction can - exist at a time so the "rwlock" is acquired during the life of a read-write - transaction. - -- `Bucket.Put()` - Writes a key/value pair into a bucket. After validating the - arguments, a cursor is used to traverse the B+tree to the page and position - where they key & value will be written. Once the position is found, the bucket - materializes the underlying page and the page's parent pages into memory as - "nodes". These nodes are where mutations occur during read-write transactions. - These changes get flushed to disk during commit. - -- `Bucket.Get()` - Retrieves a key/value pair from a bucket. This uses a cursor - to move to the page & position of a key/value pair. During a read-only - transaction, the key and value data is returned as a direct reference to the - underlying mmap file so there's no allocation overhead. For read-write - transactions, this data may reference the mmap file or one of the in-memory - node values. - -- `Cursor` - This object is simply for traversing the B+tree of on-disk pages - or in-memory nodes. It can seek to a specific key, move to the first or last - value, or it can move forward or backward. The cursor handles the movement up - and down the B+tree transparently to the end user. - -- `Tx.Commit()` - Converts the in-memory dirty nodes and the list of free pages - into pages to be written to disk. Writing to disk then occurs in two phases. - First, the dirty pages are written to disk and an `fsync()` occurs. Second, a - new meta page with an incremented transaction ID is written and another - `fsync()` occurs. This two phase write ensures that partially written data - pages are ignored in the event of a crash since the meta page pointing to them - is never written. Partially written meta pages are invalidated because they - are written with a checksum. - -If you have additional notes that could be helpful for others, please submit -them via pull request. - - -## Other Projects Using Bolt - -Below is a list of public, open source projects that use Bolt: - -* [BoltDbWeb](https://github.com/evnix/boltdbweb) - A web based GUI for BoltDB files. -* [Operation Go: A Routine Mission](http://gocode.io) - An online programming game for Golang using Bolt for user accounts and a leaderboard. -* [Bazil](https://bazil.org/) - A file system that lets your data reside where it is most convenient for it to reside. -* [DVID](https://github.com/janelia-flyem/dvid) - Added Bolt as optional storage engine and testing it against Basho-tuned leveldb. -* [Skybox Analytics](https://github.com/skybox/skybox) - A standalone funnel analysis tool for web analytics. -* [Scuttlebutt](https://github.com/benbjohnson/scuttlebutt) - Uses Bolt to store and process all Twitter mentions of GitHub projects. -* [Wiki](https://github.com/peterhellberg/wiki) - A tiny wiki using Goji, BoltDB and Blackfriday. -* [ChainStore](https://github.com/pressly/chainstore) - Simple key-value interface to a variety of storage engines organized as a chain of operations. -* [MetricBase](https://github.com/msiebuhr/MetricBase) - Single-binary version of Graphite. -* [Gitchain](https://github.com/gitchain/gitchain) - Decentralized, peer-to-peer Git repositories aka "Git meets Bitcoin". -* [event-shuttle](https://github.com/sclasen/event-shuttle) - A Unix system service to collect and reliably deliver messages to Kafka. -* [ipxed](https://github.com/kelseyhightower/ipxed) - Web interface and api for ipxed. -* [BoltStore](https://github.com/yosssi/boltstore) - Session store using Bolt. -* [photosite/session](https://godoc.org/bitbucket.org/kardianos/photosite/session) - Sessions for a photo viewing site. -* [LedisDB](https://github.com/siddontang/ledisdb) - A high performance NoSQL, using Bolt as optional storage. -* [ipLocator](https://github.com/AndreasBriese/ipLocator) - A fast ip-geo-location-server using bolt with bloom filters. -* [cayley](https://github.com/google/cayley) - Cayley is an open-source graph database using Bolt as optional backend. -* [bleve](http://www.blevesearch.com/) - A pure Go search engine similar to ElasticSearch that uses Bolt as the default storage backend. -* [tentacool](https://github.com/optiflows/tentacool) - REST api server to manage system stuff (IP, DNS, Gateway...) on a linux server. -* [Seaweed File System](https://github.com/chrislusf/seaweedfs) - Highly scalable distributed key~file system with O(1) disk read. -* [InfluxDB](https://influxdata.com) - Scalable datastore for metrics, events, and real-time analytics. -* [Freehold](http://tshannon.bitbucket.org/freehold/) - An open, secure, and lightweight platform for your files and data. -* [Prometheus Annotation Server](https://github.com/oliver006/prom_annotation_server) - Annotation server for PromDash & Prometheus service monitoring system. -* [Consul](https://github.com/hashicorp/consul) - Consul is service discovery and configuration made easy.

To do so, it introduces a few breaking changes. We've worked to keep these as minimal as possible. This guide explains the breaking changes and how you can quickly update your code. - -### `Token.Claims` is now an interface type - -The most requested feature from the 2.0 verison of this library was the ability to provide a custom type to the JSON parser for claims. This was implemented by introducing a new interface, `Claims`, to replace `map[string]interface{}`. We also included two concrete implementations of `Claims`: `MapClaims` and `StandardClaims`. - -`MapClaims` is an alias for `map[string]interface{}` with built in validation behavior. It is the default claims type when using `Parse`. The usage is unchanged except you must type cast the claims property. - -The old example for parsing a token looked like this.. - -```go - if token, err := jwt.Parse(tokenString, keyLookupFunc); err == nil { - fmt.Printf("Token for user %v expires %v", token.Claims["user"], token.Claims["exp"]) - } -``` - -is now directly mapped to... - -```go - if token, err := jwt.Parse(tokenString, keyLookupFunc); err == nil { - claims := token.Claims.(jwt.MapClaims) - fmt.Printf("Token for user %v expires %v", claims["user"], claims["exp"]) - } -``` - -`StandardClaims` is designed to be embedded in your custom type. You can supply a custom claims type with the new `ParseWithClaims` function. Here's an example of using a custom claims type. - -```go - type MyCustomClaims struct { - User string - *StandardClaims - } - - if token, err := jwt.ParseWithClaims(tokenString, &MyCustomClaims{}, keyLookupFunc); err == nil { - claims := token.Claims.(*MyCustomClaims) - fmt.Printf("Token for user %v expires %v", claims.User, claims.StandardClaims.ExpiresAt) - } -``` - -### `ParseFromRequest` has been moved - -To keep this library focused on the tokens without becoming overburdened with complex request processing logic, `ParseFromRequest` and its new companion `ParseFromRequestWithClaims` have been moved to a subpackage, `request`. The method signatues have also been augmented to receive a new argument: `Extractor`. - -`Extractors` do the work of picking the token string out of a request. The interface is simple and composable. - -This simple parsing example: - -```go - if token, err := jwt.ParseFromRequest(tokenString, req, keyLookupFunc); err == nil { - fmt.Printf("Token for user %v expires %v", token.Claims["user"], token.Claims["exp"]) - } -``` - -is directly mapped to: - -```go - if token, err := request.ParseFromRequest(req, request.OAuth2Extractor, keyLookupFunc); err == nil { - claims := token.Claims.(jwt.MapClaims) - fmt.Printf("Token for user %v expires %v", claims["user"], claims["exp"]) - } -``` - -There are several concrete `Extractor` types provided for your convenience: - -* `HeaderExtractor` will search a list of headers until one contains content. -* `ArgumentExtractor` will search a list of keys in request query and form arguments until one contains content. -* `MultiExtractor` will try a list of `Extractors` in order until one returns content. -* `AuthorizationHeaderExtractor` will look in the `Authorization` header for a `Bearer` token. -* `OAuth2Extractor` searches the places an OAuth2 token would be specified (per the spec): `Authorization` header and `access_token` argument -* `PostExtractionFilter` wraps an `Extractor`, allowing you to process the content before it's parsed. A simple example is stripping the `Bearer ` text from a header - - -### RSA signing methods no longer accept `[]byte` keys - -Due to a [critical vulnerability](https://auth0.com/blog/2015/03/31/critical-vulnerabilities-in-json-web-token-libraries/), we've decided the convenience of accepting `[]byte` instead of `rsa.PublicKey` or `rsa.PrivateKey` isn't worth the risk of misuse. - -To replace this behavior, we've added two helper methods: `ParseRSAPrivateKeyFromPEM(key []byte) (*rsa.PrivateKey, error)` and `ParseRSAPublicKeyFromPEM(key []byte) (*rsa.PublicKey, error)`. These are just simple helpers for unpacking PEM encoded PKCS1 and PKCS8 keys. If your keys are encoded any other way, all you need to do is convert them to the `crypto/rsa` package's types. - -```go - func keyLookupFunc(*Token) (interface{}, error) { - // Don't forget to validate the alg is what you expect: - if _, ok := token.Method.(*jwt.SigningMethodRSA); !ok { - return nil, fmt.Errorf("Unexpected signing method: %v", token.Header["alg"]) - } - - // Look up key - key, err := lookupPublicKey(token.Header["kid"]) - if err != nil { - return nil, err - } - - // Unpack key from PEM encoded PKCS8 - return jwt.ParseRSAPublicKeyFromPEM(key) - } -``` diff --git a/vendor/github.com/dgrijalva/jwt-go/README.md b/vendor/github.com/dgrijalva/jwt-go/README.md deleted file mode 100644 index f48365fafb..0000000000 --- a/vendor/github.com/dgrijalva/jwt-go/README.md +++ /dev/null @@ -1,85 +0,0 @@ -A [go](http://www.golang.org) (or 'golang' for search engine friendliness) implementation of [JSON Web Tokens](http://self-issued.info/docs/draft-ietf-oauth-json-web-token.html) - -[![Build Status](https://travis-ci.org/dgrijalva/jwt-go.svg?branch=master)](https://travis-ci.org/dgrijalva/jwt-go) - -**BREAKING CHANGES:*** Version 3.0.0 is here. It includes _a lot_ of changes including a few that break the API. We've tried to break as few things as possible, so there should just be a few type signature changes. A full list of breaking changes is available in `VERSION_HISTORY.md`. See `MIGRATION_GUIDE.md` for more information on updating your code. - -**NOTICE:** A vulnerability in JWT was [recently published](https://auth0.com/blog/2015/03/31/critical-vulnerabilities-in-json-web-token-libraries/). As this library doesn't force users to validate the `alg` is what they expected, it's possible your usage is effected. There will be an update soon to remedy this, and it will likey require backwards-incompatible changes to the API. In the short term, please make sure your implementation verifies the `alg` is what you expect. - - -## What the heck is a JWT? - -JWT.io has [a great introduction](https://jwt.io/introduction) to JSON Web Tokens. - -In short, it's a signed JSON object that does something useful (for example, authentication). It's commonly used for `Bearer` tokens in Oauth 2. A token is made of three parts, separated by `.`'s. The first two parts are JSON objects, that have been [base64url](http://tools.ietf.org/html/rfc4648) encoded. The last part is the signature, encoded the same way. - -The first part is called the header. It contains the necessary information for verifying the last part, the signature. For example, which encryption method was used for signing and what key was used. - -The part in the middle is the interesting bit. It's called the Claims and contains the actual stuff you care about. Refer to [the RFC](http://self-issued.info/docs/draft-jones-json-web-token.html) for information about reserved keys and the proper way to add your own. - -## What's in the box? - -This library supports the parsing and verification as well as the generation and signing of JWTs. Current supported signing algorithms are HMAC SHA, RSA, RSA-PSS, and ECDSA, though hooks are present for adding your own. - -## Examples - -See [the project documentation](https://godoc.org/github.com/dgrijalva/jwt-go) for examples of usage: - -* [Simple example of parsing and validating a token](https://godoc.org/github.com/dgrijalva/jwt-go#example-Parse--Hmac) -* [Simple example of building and signing a token](https://godoc.org/github.com/dgrijalva/jwt-go#example-New--Hmac) -* [Directory of Examples](https://godoc.org/github.com/dgrijalva/jwt-go#pkg-examples) - -## Extensions - -This library publishes all the necessary components for adding your own signing methods. Simply implement the `SigningMethod` interface and register a factory method using `RegisterSigningMethod`. - -Here's an example of an extension that integrates with the Google App Engine signing tools: https://github.com/someone1/gcp-jwt-go - -## Compliance - -This library was last reviewed to comply with [RTF 7519](http://www.rfc-editor.org/info/rfc7519) dated May 2015 with a few notable differences: - -* In order to protect against accidental use of [Unsecured JWTs](http://self-issued.info/docs/draft-ietf-oauth-json-web-token.html#UnsecuredJWT), tokens using `alg=none` will only be accepted if the constant `jwt.UnsafeAllowNoneSignatureType` is provided as the key. - -## Project Status & Versioning - -This library is considered production ready. Feedback and feature requests are appreciated. The API should be considered stable. There should be very few backwards-incompatible changes outside of major version updates (and only with good reason). - -This project uses [Semantic Versioning 2.0.0](http://semver.org). Accepted pull requests will land on `master`. Periodically, versions will be tagged from `master`. You can find all the releases on [the project releases page](https://github.com/dgrijalva/jwt-go/releases). - -While we try to make it obvious when we make breaking changes, there isn't a great mechanism for pushing announcements out to users. You may want to use this alternative package include: `gopkg.in/dgrijalva/jwt-go.v2`. It will do the right thing WRT semantic versioning. - -## Usage Tips - -### Signing vs Encryption - -A token is simply a JSON object that is signed by its author. this tells you exactly two things about the data: - -* The author of the token was in the possession of the signing secret -* The data has not been modified since it was signed - -It's important to know that JWT does not provide encryption, which means anyone who has access to the token can read its contents. If you need to protect (encrypt) the data, there is a companion spec, `JWE`, that provides this functionality. JWE is currently outside the scope of this library. - -### Choosing a Signing Method - -There are several signing methods available, and you should probably take the time to learn about the various options before choosing one. The principal design decision is most likely going to be symmetric vs asymmetric. - -Symmetric signing methods, such as HSA, use only a single secret. This is probably the simplest signing method to use since any `[]byte` can be used as a valid secret. They are also slightly computationally faster to use, though this rarely is enough to matter. Symmetric signing methods work the best when both producers and consumers of tokens are trusted, or even the same system. Since the same secret is used to both sign and validate tokens, you can't easily distribute the key for validation. - -Asymmetric signing methods, such as RSA, use different keys for signing and verifying tokens. This makes it possible to produce tokens with a private key, and allow any consumer to access the public key for verification. - -### JWT and OAuth - -It's worth mentioning that OAuth and JWT are not the same thing. A JWT token is simply a signed JSON object. It can be used anywhere such a thing is useful. There is some confusion, though, as JWT is the most common type of bearer token used in OAuth2 authentication. - -Without going too far down the rabbit hole, here's a description of the interaction of these technologies: - -* OAuth is a protocol for allowing an identity provider to be separate from the service a user is logging in to. For example, whenever you use Facebook to log into a different service (Yelp, Spotify, etc), you are using OAuth. -* OAuth defines several options for passing around authentication data. One popular method is called a "bearer token". A bearer token is simply a string that _should_ only be held by an authenticated user. Thus, simply presenting this token proves your identity. You can probably derive from here why a JWT might make a good bearer token. -* Because bearer tokens are used for authentication, it's important they're kept secret. This is why transactions that use bearer tokens typically happen over SSL. - -## More - -Documentation can be found [on godoc.org](http://godoc.org/github.com/dgrijalva/jwt-go). - -The command line utility included in this project (cmd/jwt) provides a straightforward example of token creation and parsing as well as a useful tool for debugging your own integration. You'll also find several implementation examples in to documentation. diff --git a/vendor/github.com/dgrijalva/jwt-go/VERSION_HISTORY.md b/vendor/github.com/dgrijalva/jwt-go/VERSION_HISTORY.md deleted file mode 100644 index b605b45093..0000000000 --- a/vendor/github.com/dgrijalva/jwt-go/VERSION_HISTORY.md +++ /dev/null @@ -1,105 +0,0 @@ -## `jwt-go` Version History - -#### 3.0.0 - -* **Compatibility Breaking Changes**: See MIGRATION_GUIDE.md for tips on updating your code - * Dropped support for `[]byte` keys when using RSA signing methods. This convenience feature could contribute to security vulnerabilities involving mismatched key types with signing methods. - * `ParseFromRequest` has been moved to `request` subpackage and usage has changed - * The `Claims` property on `Token` is now type `Claims` instead of `map[string]interface{}`.

The first was a refactor required to expand the width of the RSA and HMAC-SHA signing implementations. There will likely be no required code changes to support this change. - -The second update, while unfortunately requiring a small change in integration, is required to open up this library to other signing methods. Not all keys used for all signing methods have a single standard on-disk representation. Requiring `[]byte` as the type for all keys proved too limiting. Additionally, this implementation allows for pre-parsed tokens to be reused, which might matter in an application that parses a high volume of tokens with a small set of keys. Backwards compatibilty has been maintained for passing `[]byte` to the RSA signing methods, but they will also accept `*rsa.PublicKey` and `*rsa.PrivateKey`. - -It is likely the only integration change required here will be to change `func(t *jwt.Token) ([]byte, error)` to `func(t *jwt.Token) (interface{}, error)` when calling `Parse`. - -* **Compatibility Breaking Changes** - * `SigningMethodHS256` is now `*SigningMethodHMAC` instead of `type struct` - * `SigningMethodRS256` is now `*SigningMethodRSA` instead of `type struct` - * `KeyFunc` now returns `interface{}` instead of `[]byte` - * `SigningMethod.Sign` now takes `interface{}` instead of `[]byte` for the key - * `SigningMethod.Verify` now takes `interface{}` instead of `[]byte` for the key -* Renamed type `SigningMethodHS256` to `SigningMethodHMAC`.

Sharded indices provide lower write latencies for indices with large amounts of data. -- __Index metadata__: Track index version for easily managing migrations and schema changes. diff --git a/vendor/github.com/facebookgo/clock/README.md b/vendor/github.com/facebookgo/clock/README.md deleted file mode 100644 index 5d4f4fe72e..0000000000 --- a/vendor/github.com/facebookgo/clock/README.md +++ /dev/null @@ -1,104 +0,0 @@ -clock [![Build Status](https://drone.io/github.com/benbjohnson/clock/status.png)](https://drone.io/github.com/benbjohnson/clock/latest) [![Coverage Status](https://coveralls.io/repos/benbjohnson/clock/badge.png?branch=master)](https://coveralls.io/r/benbjohnson/clock?branch=master) [![GoDoc](https://godoc.org/github.com/benbjohnson/clock?status.png)](https://godoc.org/github.com/benbjohnson/clock) ![Project status](http://img.shields.io/status/experimental.png?color=red) -===== - -Clock is a small library for mocking time in Go. It provides an interface -around the standard library's [`time`][time] package so that the application -can use the realtime clock while tests can use the mock clock. - -[time]: http://golang.org/pkg/time/ - - -## Usage - -### Realtime Clock - -Your application can maintain a `Clock` variable that will allow realtime and -mock clocks to be interchangable. For example, if you had an `Application` type: - -```go -import "github.com/benbjohnson/clock" - -type Application struct { - Clock clock.Clock -} -``` - -You could initialize it to use the realtime clock like this: - -```go -var app Application -app.Clock = clock.New() -... -``` - -Then all timers and time-related functionality should be performed from the -`Clock` variable. - - -### Mocking time - -In your tests, you will want to use a `Mock` clock: - -```go -import ( - "testing" - - "github.com/benbjohnson/clock" -) - -func TestApplication_DoSomething(t *testing.T) { - mock := clock.NewMock() - app := Application{Clock: mock} - ... -} -``` - -Now that you've initialized your application to use the mock clock, you can -adjust the time programmatically. The mock clock always starts from the Unix -epoch (midnight, Jan 1, 1970 UTC). - - -### Controlling time - -The mock clock provides the same functions that the standard library's `time` -package provides. For example, to find the current time, you use the `Now()` -function: - -```go -mock := clock.NewMock() - -// Find the current time. -mock.Now().UTC() // 1970-01-01 00:00:00 +0000 UTC - -// Move the clock forward. -mock.Add(2 * time.Hour) - -// Check the time again. It's 2 hours later! -mock.Now().UTC() // 1970-01-01 02:00:00 +0000 UTC -``` - -Timers and Tickers are also controlled by this same mock clock. They will only -execute when the clock is moved forward: - -``` -mock := clock.NewMock() -count := 0 - -// Kick off a timer to increment every 1 mock second. -go func() { - ticker := clock.Ticker(1 * time.Second) - for { - <-ticker.C - count++ - } -}() -runtime.Gosched() - -// Move the clock forward 10 second. -mock.Add(10 * time.Second) - -// This prints 10. -fmt.Println(count) -``` - - diff --git a/vendor/github.com/facebookgo/httpdown/readme.md b/vendor/github.com/facebookgo/httpdown/readme.md deleted file mode 100644 index d5fa245dbc..0000000000 --- a/vendor/github.com/facebookgo/httpdown/readme.md +++ /dev/null @@ -1,41 +0,0 @@ -httpdown [![Build Status](https://secure.travis-ci.org/facebookgo/httpdown.png)](https://travis-ci.org/facebookgo/httpdown) -======== - -Documentation: https://godoc.org/github.com/facebookgo/httpdown - -Package httpdown provides a library that makes it easy to build a HTTP server -that can be shutdown gracefully (that is, without dropping any connections). - -If you want graceful restart and not just graceful shutdown, look at the -[grace](https://github.com/facebookgo/grace) package which uses this package -underneath but also provides graceful restart. - -Usage ------ - -Demo HTTP Server with graceful termination: -https://github.com/facebookgo/httpdown/blob/master/httpdown_example/main.go - -1.

Think of it as a train of boxcars: the streaming format breaks your data in chunks, applies snappy to each chunk alone, then puts a thin wrapper around the chunk, and sends it along in turn. You can begin decoding before receiving everything. And memory requirements for decoding are sane. - -Strangely, though the streaming format was first proposed in Go[1][2], it was never upated, and I could not locate any other library for Go that would handle the streaming/framed snappy format. Hence this implementation of the spec. There is a command line tool[3] that has a C implementation, but this is the only Go implementation that I am aware of. The reference for the framing/streaming spec seems to be the python implementation[4]. - -For binary compatibility with the python implementation, one could use the C-snappy compressor/decompressor code directly; using github.com/dgryski/go-csnappy. In fact we did this for a while to verify byte-for-byte compatiblity, as the native Go implementation produces slightly different binary compression (still conformant with the standard of course), which made test-diffs harder, and some have complained about it being slower than the C. - -However, while the c-snappy was useful for checking compatibility, it introduced dependencies on external C libraries (both the c-snappy library and the C standard library). Our go binary executable that used the go-unsnap-stream library was no longer standalone, and deployment was painful if not impossible if the target had a different C standard library. So we've gone back to using the snappy-go implementation (entirely in Go) for ease of deployment.

If multiple charsets are set (separated by a comma), the following charset is used if setting the charset failes. This enables for example support for `utf8mb4` ([introduced in MySQL 5.5.3](http://dev.mysql.com/doc/refman/5.5/en/charset-unicode-utf8mb4.html)) with fallback to `utf8` for older servers (`charset=utf8mb4,utf8`). - -Usage of the `charset` parameter is discouraged because it issues additional queries to the server. -Unless you need the fallback behavior, please use `collation` instead. - -##### `collation` - -``` -Type: string -Valid Values: -Default: utf8_general_ci -``` - -Sets the collation used for client-server interaction on connection. In contrast to `charset`, `collation` does not issue additional queries. If the specified collation is unavailable on the target server, the connection will fail. - -A list of valid charsets for a server is retrievable with `SHOW COLLATION`. - -##### `clientFoundRows` - -``` -Type: bool -Valid Values: true, false -Default: false -``` - -`clientFoundRows=true` causes an UPDATE to return the number of matching rows instead of the number of rows changed. - -##### `columnsWithAlias` - -``` -Type: bool -Valid Values: true, false -Default: false -``` - -When `columnsWithAlias` is true, calls to `sql.Rows.Columns()` will return the table alias and the column name separated by a dot. For example: - -``` -SELECT u.id FROM users as u -``` - -will return `u.id` instead of just `id` if `columnsWithAlias=true`. - -##### `interpolateParams` - -``` -Type: bool -Valid Values: true, false -Default: false -``` - -If `interpolateParams` is true, placeholders (`?`) in calls to `db.Query()` and `db.Exec()` are interpolated into a single query string with given parameters. This reduces the number of roundtrips, since the driver has to prepare a statement, execute it with given parameters and close the statement again with `interpolateParams=false`. - -*This can not be used together with the multibyte encodings BIG5, CP932, GB2312, GBK or SJIS. These are blacklisted as they may [introduce a SQL injection vulnerability](http://stackoverflow.com/a/12118602/3430118)!* - -##### `loc` - -``` -Type: string -Valid Values: -Default: UTC -``` - -Sets the location for time.Time values (when using `parseTime=true`). *"Local"* sets the system's location. See [time.LoadLocation](http://golang.org/pkg/time/#LoadLocation) for details. - -Note that this sets the location for time.Time values but does not change MySQL's [time_zone setting](https://dev.mysql.com/doc/refman/5.5/en/time-zone-support.html). For that see the [time_zone system variable](#system-variables), which can also be set as a DSN parameter. - -Please keep in mind, that param values must be [url.QueryEscape](http://golang.org/pkg/net/url/#QueryEscape)'ed. Alternatively you can manually replace the `/` with `%2F`. For example `US/Pacific` would be `loc=US%2FPacific`. - -##### `maxAllowedPacket` -``` -Type: decimal number -Default: 0 -``` - -Max packet size allowed in bytes. Use `maxAllowedPacket=0` to automatically fetch the `max_allowed_packet` variable from server. - -##### `multiStatements` - -``` -Type: bool -Valid Values: true, false -Default: false -``` - -Allow multiple statements in one query. While this allows batch queries, it also greatly increases the risk of SQL injections. Only the result of the first query is returned, all other results are silently discarded. - -When `multiStatements` is used, `?` parameters must only be used in the first statement. - -##### `parseTime` - -``` -Type: bool -Valid Values: true, false -Default: false -``` - -`parseTime=true` changes the output type of `DATE` and `DATETIME` values to `time.Time` instead of `[]byte` / `string` - - -##### `readTimeout` - -``` -Type: decimal number -Default: 0 -``` - -I/O read timeout. The value must be a decimal number with an unit suffix ( *"ms"*, *"s"*, *"m"*, *"h"* ), such as *"30s"*, *"0.5m"* or *"1m30s"*. - -##### `strict` - -``` -Type: bool -Valid Values: true, false -Default: false -``` - -`strict=true` enables a driver-side strict mode in which MySQL warnings are treated as errors. This mode should not be used in production as it may lead to data corruption in certain situations. - -A server-side strict mode, which is safe for production use, can be set via the [`sql_mode`](https://dev.mysql.com/doc/refman/5.7/en/sql-mode.html) system variable. - -By default MySQL also treats notes as warnings. Use [`sql_notes=false`](http://dev.mysql.com/doc/refman/5.7/en/server-system-variables.html#sysvar_sql_notes) to ignore notes. - -##### `timeout` - -``` -Type: decimal number -Default: OS default -``` - -*Driver* side connection timeout. The value must be a decimal number with an unit suffix ( *"ms"*, *"s"*, *"m"*, *"h"* ), such as *"30s"*, *"0.5m"* or *"1m30s"*. To set a server side timeout, use the parameter [`wait_timeout`](http://dev.mysql.com/doc/refman/5.6/en/server-system-variables.html#sysvar_wait_timeout). - -##### `tls` - -``` -Type: bool / string -Valid Values: true, false, skip-verify, -Default: false -``` - -`tls=true` enables TLS / SSL encrypted connection to the server. Use `skip-verify` if you want to use a self-signed or invalid certificate (server side). Use a custom value registered with [`mysql.RegisterTLSConfig`](http://godoc.org/github.com/go-sql-driver/mysql#RegisterTLSConfig). - -##### `writeTimeout` - -``` -Type: decimal number -Default: 0 -``` - -I/O write timeout. The value must be a decimal number with an unit suffix ( *"ms"*, *"s"*, *"m"*, *"h"* ), such as *"30s"*, *"0.5m"* or *"1m30s"*. - - -##### System Variables - -All other parameters are interpreted as system variables: - * `autocommit`: `"SET autocommit="` - * [`time_zone`](https://dev.mysql.com/doc/refman/5.5/en/time-zone-support.html): `"SET time_zone="` - * [`tx_isolation`](https://dev.mysql.com/doc/refman/5.5/en/server-system-variables.html#sysvar_tx_isolation): `"SET tx_isolation="` - * `param`: `"SET ="` - -*The values must be [url.QueryEscape](http://golang.org/pkg/net/url/#QueryEscape)'ed!* - -#### Examples -``` -user@unix(/path/to/socket)/dbname -``` - -``` -root:pw@unix(/tmp/mysql.sock)/myDatabase?loc=Local -``` - -``` -user:password@tcp(localhost:5555)/dbname?tls=skip-verify&autocommit=true -``` - -Treat warnings as errors by setting the system variable [`sql_mode`](https://dev.mysql.com/doc/refman/5.7/en/sql-mode.html): -``` -user:password@/dbname?sql_mode=TRADITIONAL -``` - -TCP via IPv6: -``` -user:password@tcp([de:ad:be:ef::ca:fe]:80)/dbname?timeout=90s&collation=utf8mb4_unicode_ci -``` - -TCP on a remote host, e.g. Amazon RDS: -``` -id:password@tcp(your-amazonaws-uri.com:3306)/dbname -``` - -Google Cloud SQL on App Engine (First Generation MySQL Server): -``` -user@cloudsql(project-id:instance-name)/dbname -``` - -Google Cloud SQL on App Engine (Second Generation MySQL Server): -``` -user@cloudsql(project-id:regionname:instance-name)/dbname -``` - -TCP using default port (3306) on localhost: -``` -user:password@tcp/dbname?charset=utf8mb4,utf8&sys_var=esc%40ped -``` - -Use the default protocol (tcp) and host (localhost:3306): -``` -user:password@/dbname -``` - -No Database preselected: -``` -user:password@/ -``` - -### `LOAD DATA LOCAL INFILE` support -For this feature you need direct access to the package. Therefore you must change the import path (no `_`): -```go -import "github.com/go-sql-driver/mysql" -``` - -Files must be whitelisted by registering them with `mysql.RegisterLocalFile(filepath)` (recommended) or the Whitelist check must be deactivated by using the DSN parameter `allowAllFiles=true` ([*Might be insecure!*](http://dev.mysql.com/doc/refman/5.7/en/load-data-local.html)). - -To use a `io.Reader` a handler function must be registered with `mysql.RegisterReaderHandler(name, handler)` which returns a `io.Reader` or `io.ReadCloser`. The Reader is available with the filepath `Reader::` then. Choose different names for different handlers and `DeregisterReaderHandler` when you don't need it anymore. - -See the [godoc of Go-MySQL-Driver](http://godoc.org/github.com/go-sql-driver/mysql "golang mysql driver documentation") for details. - - -### `time.Time` support -The default internal output type of MySQL `DATE` and `DATETIME` values is `[]byte` which allows you to scan the value into a `[]byte`, `string` or `sql.RawBytes` variable in your programm. - -However, many want to scan MySQL `DATE` and `DATETIME` values into `time.Time` variables, which is the logical opposite in Go to `DATE` and `DATETIME` in MySQL. You can do that by changing the internal output type from `[]byte` to `time.Time` with the DSN parameter `parseTime=true`. You can set the default [`time.Time` location](http://golang.org/pkg/time/#Location) with the `loc` DSN parameter. - -**Caution:** As of Go 1.1, this makes `time.Time` the only variable type you can scan `DATE` and `DATETIME` values into. This breaks for example [`sql.RawBytes` support](https://github.com/go-sql-driver/mysql/wiki/Examples#rawbytes). - -Alternatively you can use the [`NullTime`](http://godoc.org/github.com/go-sql-driver/mysql#NullTime) type as the scan destination, which works with both `time.Time` and `string` / `[]byte`. - - -### Unicode support -Since version 1.1 Go-MySQL-Driver automatically uses the collation `utf8_general_ci` by default. - -Other collations / charsets can be set using the [`collation`](#collation) DSN parameter. - -Version 1.0 of the driver recommended adding `&charset=utf8` (alias for `SET NAMES utf8`) to the DSN to enable proper UTF-8 support. This is not necessary anymore. The [`collation`](#collation) parameter should be preferred to set another collation / charset than the default. - -See http://dev.mysql.com/doc/refman/5.7/en/charset-unicode.html for more details on MySQL's Unicode support. - - -## Testing / Development -To run the driver tests you may need to adjust the configuration. See the [Testing Wiki-Page](https://github.com/go-sql-driver/mysql/wiki/Testing "Testing") for details. - -Go-MySQL-Driver is not feature-complete yet.

Like the standard `http.ServeMux`, `mux.Router` matches incoming requests against a list of registered routes and calls a handler for the route that matches the URL or other conditions. The main features are: - -* It implements the `http.Handler` interface so it is compatible with the standard `http.ServeMux`. -* Requests can be matched based on URL host, path, path prefix, schemes, header and query values, HTTP methods or using custom matchers. -* URL hosts and paths can have variables with an optional regular expression. -* Registered URLs can be built, or "reversed", which helps maintaining references to resources. -* Routes can be used as subrouters: nested routes are only tested if the parent route matches. This is useful to define groups of routes that share common conditions like a host, a path prefix or other repeated attributes. As a bonus, this optimizes request matching. - ---- - -* [Install](#install) -* [Examples](#examples) -* [Matching Routes](#matching-routes) -* [Static Files](#static-files) -* [Registered URLs](#registered-urls) -* [Full Example](#full-example) - ---- - -## Install - -With a [correctly configured](https://golang.org/doc/install#testing) Go toolchain: - -```sh -go get -u github.com/gorilla/mux -``` - -## Examples - -Let's start registering a couple of URL paths and handlers: - -```go -func main() { - r := mux.NewRouter() - r.HandleFunc("/", HomeHandler) - r.HandleFunc("/products", ProductsHandler) - r.HandleFunc("/articles", ArticlesHandler) - http.Handle("/", r) -} -``` - -Here we register three routes mapping URL paths to handlers. This is equivalent to how `http.HandleFunc()` works: if an incoming request URL matches one of the paths, the corresponding handler is called passing (`http.ResponseWriter`, `*http.Request`) as parameters. - -Paths can have variables. They are defined using the format `{name}` or `{name:pattern}`. If a regular expression pattern is not defined, the matched variable will be anything until the next slash. For example: - -```go -r := mux.NewRouter() -r.HandleFunc("/products/{key}", ProductHandler) -r.HandleFunc("/articles/{category}/", ArticlesCategoryHandler) -r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler) -``` - -The names are used to create a map of route variables which can be retrieved calling `mux.Vars()`: - -```go -vars := mux.Vars(request) -category := vars["category"] -``` - -And this is all you need to know about the basic usage. More advanced options are explained below. - -### Matching Routes - -Routes can also be restricted to a domain or subdomain. Just define a host pattern to be matched. They can also have variables: - -```go -r := mux.NewRouter() -// Only matches if domain is "www.example.com". -r.Host("www.example.com") -// Matches a dynamic subdomain. -r.Host("{subdomain:[a-z]+}.domain.com") -``` - -There are several other matchers that can be added. To match path prefixes: - -```go -r.PathPrefix("/products/") -``` - -...or HTTP methods: - -```go -r.Methods("GET", "POST") -``` - -...or URL schemes: - -```go -r.Schemes("https") -``` - -...or header values: - -```go -r.Headers("X-Requested-With", "XMLHttpRequest") -``` - -...or query values: - -```go -r.Queries("key", "value") -``` - -...or to use a custom matcher function: - -```go -r.MatcherFunc(func(r *http.Request, rm *RouteMatch) bool { - return r.ProtoMajor == 0 -}) -``` - -...and finally, it is possible to combine several matchers in a single route: - -```go -r.HandleFunc("/products", ProductsHandler). - Host("www.example.com"). - Methods("GET"). - Schemes("http") -``` - -Setting the same matching conditions again and again can be boring, so we have a way to group several routes that share the same requirements. We call it "subrouting". - -For example, let's say we have several URLs that should only match when the host is `www.example.com`. Create a route for that host and get a "subrouter" from it: - -```go -r := mux.NewRouter() -s := r.Host("www.example.com").Subrouter() -``` - -Then register routes in the subrouter: - -```go -s.HandleFunc("/products/", ProductsHandler) -s.HandleFunc("/products/{key}", ProductHandler) -s.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler) -``` - -The three URL paths we registered above will only be tested if the domain is `www.example.com`, because the subrouter is tested first. This is not only convenient, but also optimizes request matching. You can create subrouters combining any attribute matchers accepted by a route. - -Subrouters can be used to create domain or path "namespaces": you define subrouters in a central place and then parts of the app can register its paths relatively to a given subrouter. - -There's one more thing about subroutes. When a subrouter has a path prefix, the inner routes use it as base for their paths: - -```go -r := mux.NewRouter() -s := r.PathPrefix("/products").Subrouter() -// "/products/" -s.HandleFunc("/", ProductsHandler) -// "/products/{key}/" -s.HandleFunc("/{key}/", ProductHandler) -// "/products/{key}/details" -s.HandleFunc("/{key}/details", ProductDetailsHandler) -``` - -### Static Files - -Note that the path provided to `PathPrefix()` represents a "wildcard": calling -`PathPrefix("/static/").Handler(...)` means that the handler will be passed any -request that matches "/static/*". This makes it easy to serve static files with mux: - -```go -func main() { - var dir string - - flag.StringVar(&dir, "dir", ".", "the directory to serve files from. Defaults to the current dir") - flag.Parse() - r := mux.NewRouter() - - // This will serve files under http://localhost:8000/static/ - r.PathPrefix("/static/").Handler(http.StripPrefix("/static/", http.FileServer(http.Dir(dir)))) - - srv := &http.Server{ - Handler: r, - Addr: "127.0.0.1:8000", - // Good practice: enforce timeouts for servers you create! - WriteTimeout: 15 * time.Second, - ReadTimeout: 15 * time.Second, - } - - log.Fatal(srv.ListenAndServe()) -} -``` - -### Registered URLs - -Now let's see how to build registered URLs. - -Routes can be named. All routes that define a name can have their URLs built, or "reversed". We define a name calling `Name()` on a route. For example: - -```go -r := mux.NewRouter() -r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler). - Name("article") -``` - -To build a URL, get the route and call the `URL()` method, passing a sequence of key/value pairs for the route variables. For the previous route, we would do: - -```go -url, err := r.Get("article").URL("category", "technology", "id", "42") -``` - -...and the result will be a `url.URL` with the following path: - -``` -"/articles/technology/42" -``` - -This also works for host variables: - -```go -r := mux.NewRouter() -r.Host("{subdomain}.domain.com"). - Path("/articles/{category}/{id:[0-9]+}"). - HandlerFunc(ArticleHandler). - Name("article") - -// url.String() will be "http://news.domain.com/articles/technology/42" -url, err := r.Get("article").URL("subdomain", "news", - "category", "technology", - "id", "42") -``` - -All variables defined in the route are required, and their values must conform to the corresponding patterns. These requirements guarantee that a generated URL will always match a registered route -- the only exception is for explicitly defined "build-only" routes which never match. - -Regex support also exists for matching Headers within a route. For example, we could do: - -```go -r.HeadersRegexp("Content-Type", "application/(text|json)") -``` - -...and the route will match both requests with a Content-Type of `application/json` as well as `application/text` - -There's also a way to build only the URL host or path for a route: use the methods `URLHost()` or `URLPath()` instead. For the previous route, we would do: - -```go -// "http://news.domain.com/" -host, err := r.Get("article").URLHost("subdomain", "news") - -// "/articles/technology/42" -path, err := r.Get("article").URLPath("category", "technology", "id", "42") -``` - -And if you use subrouters, host and path defined separately can be built as well: - -```go -r := mux.NewRouter() -s := r.Host("{subdomain}.domain.com").Subrouter() -s.Path("/articles/{category}/{id:[0-9]+}"). - HandlerFunc(ArticleHandler). - Name("article") - -// "http://news.domain.com/articles/technology/42" -url, err := r.Get("article").URL("subdomain", "news", - "category", "technology", - "id", "42") -``` - -## Full Example - -Here's a complete, runnable example of a small `mux` based server: - -```go -package main - -import ( - "net/http" - "log" - "github.com/gorilla/mux" -) - -func YourHandler(w http.ResponseWriter, r *http.Request) { - w.Write([]byte("Gorilla!\n")) -} - -func main() { - r := mux.NewRouter() - // Routes consist of a path and a handler function. - r.HandleFunc("/", YourHandler) - - // Bind to a port and pass our router in - log.Fatal(http.ListenAndServe(":8000", r)) -} -``` - -## License - -BSD licensed.

We focus on simply ensuring that whatever elements do exist are described in the policy whitelist and that attributes and links are safe for use on your web page. [GIGO](http://en.wikipedia.org/wiki/Garbage_in,_garbage_out) does apply and if you feed it bad HTML bluemonday is not tasked with figuring out how to make it good again. - -### Supported Go Versions - -bluemonday is regularly tested against Go 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7 and tip. - -We do not support Go 1.0 as we depend on `golang.org/x/net/html` which includes a reference to `io.ErrNoProgress` which did not exist in Go 1.0. - -## Is it production ready? - -*Yes* - -We are using bluemonday in production having migrated from the widely used and heavily field tested OWASP Java HTML Sanitizer. - -We are passing our extensive test suite (including AntiSamy tests as well as tests for any issues raised). Check for any [unresolved issues](https://github.com/microcosm-cc/bluemonday/issues?page=1&state=open) to see whether anything may be a blocker for you. - -We invite pull requests and issues to help us ensure we are offering comprehensive protection against various attacks via user generated content. - -## Usage - -Install in your `${GOPATH}` using `go get -u github.com/microcosm-cc/bluemonday` - -Then call it: -```go -package main - -import ( - "fmt" - - "github.com/microcosm-cc/bluemonday" -) - -func main() { - p := bluemonday.UGCPolicy() - html := p.Sanitize( - `Google`, - ) - - // Output: - // Google - fmt.Println(html) -} -``` - -We offer three ways to call Sanitize: -```go -p.Sanitize(string) string -p.SanitizeBytes([]byte) []byte -p.SanitizeReader(io.Reader) bytes.Buffer -``` - -If you are obsessed about performance, `p.SanitizeReader(r).Bytes()` will return a `[]byte` without performing any unnecessary casting of the inputs or outputs. Though the difference is so negligible you should never need to care. - -You can build your own policies: -```go -package main - -import ( - "fmt" - - "github.com/microcosm-cc/bluemonday" -) - -func main() { - p := bluemonday.NewPolicy() - - // Require URLs to be parseable by net/url.Parse and either: - // mailto: http:// or https:// - p.AllowStandardURLs() - - // We only allow

and - p.AllowAttrs("href").OnElements("a") - p.AllowElements("p") - - html := p.Sanitize( - `Google`, - ) - - // Output: - // Google - fmt.Println(html) -} -``` - -We ship two default policies: - -1. `bluemonday.StrictPolicy()` which can be thought of as equivalent to stripping all HTML elements and their attributes as it has nothing on it's whitelist. An example usage scenario would be blog post titles where HTML tags are not expected at all and if they are then the elements *and* the content of the elements should be stripped. This is a *very* strict policy. -2. `bluemonday.UGCPolicy()` which allows a broad selection of HTML elements and attributes that are safe for user generated content. Note that this policy does *not* whitelist iframes, object, embed, styles, script, etc. An example usage scenario would be blog post bodies where a variety of formatting is expected along with the potential for TABLEs and IMGs. - -## Policy Building - -The essence of building a policy is to determine which HTML elements and attributes are considered safe for your scenario. OWASP provide an [XSS prevention cheat sheet](https://www.owasp.org/index.php/XSS_(Cross_Site_Scripting)_Prevention_Cheat_Sheet) to help explain the risks, but essentially: - -1. Avoid anything other than the standard HTML elements -1. Avoid `script`, `style`, `iframe`, `object`, `embed`, `base` elements that allow code to be executed by the client or third party content to be included that can execute code -1. Avoid anything other than plain HTML attributes with values matched to a regexp - -Basically, you should be able to describe what HTML is fine for your scenario. If you do not have confidence that you can describe your policy please consider using one of the shipped policies such as `bluemonday.UGCPolicy()`. - -To create a new policy: -```go -p := bluemonday.NewPolicy() -``` - -To add elements to a policy either add just the elements: -```go -p.AllowElements("b", "strong") -``` - -Or add elements as a virtue of adding an attribute: -```go -// Not the recommended pattern, see the recommendation on using .Matching() below -p.AllowAttrs("nowrap").OnElements("td", "th") -``` - -Attributes can either be added to all elements: -```go -p.AllowAttrs("dir").Matching(regexp.MustCompile("(?i)rtl|ltr")).Globally() -``` - -Or attributes can be added to specific elements: -```go -// Not the recommended pattern, see the recommendation on using .Matching() below -p.AllowAttrs("value").OnElements("li") -``` - -It is **always** recommended that an attribute be made to match a pattern. XSS in HTML attributes is very easy otherwise: -```go -// \p{L} matches unicode letters, \p{N} matches unicode numbers -p.AllowAttrs("title").Matching(regexp.MustCompile(`[\p{L}\p{N}\s\-_',:\[\]!\./\\\(\)&]*`)).Globally() -``` - -You can stop at any time and call .Sanitize(): -```go -// string htmlIn passed in from a HTTP POST -htmlOut := p.Sanitize(htmlIn) -``` - -And you can take any existing policy and extend it: -```go -p := bluemonday.UGCPolicy() -p.AllowElements("fieldset", "select", "option") -``` - -### Links - -Links are difficult beasts to sanitise safely and also one of the biggest attack vectors for malicious content. - -It is possible to do this: -```go -p.AllowAttrs("href").Matching(regexp.MustCompile(`(?i)mailto|https?`)).OnElements("a") -``` - -But that will not protect you as the regular expression is insufficient in this case to have prevented a malformed value doing something unexpected. - -We provide some additional global options for safely working with links. - -`RequireParseableURLs` will ensure that URLs are parseable by Go's `net/url` package: -```go -p.RequireParseableURLs(true) -``` - -If you have enabled parseable URLs then the following option will `AllowRelativeURLs`. By default this is disabled (bluemonday is a whitelist tool... you need to explicitly tell us to permit things) and when disabled it will prevent all local and scheme relative URLs (i.e. `href="localpage.html"`, `href="../home.html"` and even `href="//www.google.com"` are relative): -```go -p.AllowRelativeURLs(true) -``` - -If you have enabled parseable URLs then you can whitelist the schemes (commonly called protocol when thinking of `http` and `https`) that are permitted. Bear in mind that allowing relative URLs in the above option will allow for a blank scheme: -```go -p.AllowURLSchemes("mailto", "http", "https") -``` - -Regardless of whether you have enabled parseable URLs, you can force all URLs to have a rel="nofollow" attribute. This will be added if it does not exist, but only when the `href` is valid: -```go -// This applies to "a" "area" "link" elements that have a "href" attribute -p.RequireNoFollowOnLinks(true) -``` - -We provide a convenience method that applies all of the above, but you will still need to whitelist the linkable elements for the URL rules to be applied to: -```go -p.AllowStandardURLs() -p.AllowAttrs("cite").OnElements("blockquote", "q") -p.AllowAttrs("href").OnElements("a", "area") -p.AllowAttrs("src").OnElements("img") -``` - -An additional complexity regarding links is the data URI as defined in [RFC2397](http://tools.ietf.org/html/rfc2397). The data URI allows for images to be served inline using this format: - -```html - -``` - -We have provided a helper to verify the mimetype followed by base64 content of data URIs links: - -```go -p.AllowDataURIImages() -``` - -That helper will enable GIF, JPEG, PNG and WEBP images. - -It should be noted that there is a potential [security](http://palizine.plynt.com/issues/2010Oct/bypass-xss-filters/) [risk](https://capec.mitre.org/data/definitions/244.html) with the use of data URI links. You should only enable data URI links if you already trust the content. - -We also have some features to help deal with user generated content: -```go -p.AddTargetBlankToFullyQualifiedLinks(true) -``` - -This will ensure that anchor `` links that are fully qualified (the href destination includes a host name) will get `target="_blank"` added to them. - -Additionally any link that has `target="_blank"` after the policy has been applied will also have the `rel` attribute adjusted to add `noopener`. This means a link may start like `` and will end up as ``. It is important to note that the addition of `noopener` is a security feature and not an issue. There is an unfortunate feature to browsers that a browser window opened as a result of `target="_blank"` can still control the opener (your web page) and this protects against that. The background to this can be found here: [https://dev.to/ben/the-targetblank-vulnerability-by-example](https://dev.to/ben/the-targetblank-vulnerability-by-example) - -### Policy Building Helpers - -We also bundle some helpers to simplify policy building: -```go - -// Permits the "dir", "id", "lang", "title" attributes globally -p.AllowStandardAttributes() - -// Permits the "img" element and it's standard attributes -p.AllowImages() - -// Permits ordered and unordered lists, and also definition lists -p.AllowLists() - -// Permits HTML tables and all applicable elements and non-styling attributes -p.AllowTables() -``` - -### Invalid Instructions - -The following are invalid: -```go -// This does not say where the attributes are allowed, you need to add -// .Globally() or .OnElements(...) -// This will be ignored without error. -p.AllowAttrs("value") - -// This does not say where the attributes are allowed, you need to add -// .Globally() or .OnElements(...) -// This will be ignored without error. -p.AllowAttrs( - "type", -).Matching( - regexp.MustCompile("(?i)^(circle|disc|square|a|A|i|I|1)$"), -) -``` - -Both examples exhibit the same issue, they declare attributes but do not then specify whether they are whitelisted globally or only on specific elements (and which elements). Attributes belong to one or more elements, and the policy needs to declare this. - -## Limitations - -We are not yet including any tools to help whitelist and sanitize CSS. Which means that unless you wish to do the heavy lifting in a single regular expression (inadvisable), **you should not allow the "style" attribute anywhere**. - -It is not the job of bluemonday to fix your bad HTML, it is merely the job of bluemonday to prevent malicious HTML getting through. If you have mismatched HTML elements, or non-conforming nesting of elements, those will remain. But if you have well-structured HTML bluemonday will not break it. - -## TODO - -* Add support for CSS sanitisation to allow some CSS properties based on a whitelist, possibly using the [Gorilla CSS3 scanner](http://www.gorillatoolkit.org/pkg/css/scanner) -* Investigate whether devs want to blacklist elements and attributes. This would allow devs to take an existing policy (such as the `bluemonday.UGCPolicy()` ) that encapsulates 90% of what they're looking for but does more than they need, and to remove the extra things they do not want to make it 100% what they want -* Investigate whether devs want a validating HTML mode, in which the HTML elements are not just transformed into a balanced tree (every start tag has a closing tag at the correct depth) but also that elements and character data appear only in their allowed context (i.e. that a `table` element isn't a descendent of a `caption`, that `colgroup`, `thead`, `tbody`, `tfoot` and `tr` are permitted, and that character data is not permitted) - -## Development - -If you have cloned this repo you will probably need the dependency: - -`go get golang.org/x/net/html` - -Gophers can use their familiar tools: - -`go build` - -`go test` - -I personally use a Makefile as it spares typing the same args over and over whilst providing consistency for those of us who jump from language to language and enjoy just typing `make` in a project directory and watch magic happen. - -`make` will build, vet, test and install the library. - -`make clean` will remove the library from a *single* `${GOPATH}/pkg` directory tree - -`make test` will run the tests - -`make cover` will run the tests and *open a browser window* with the coverage report - -`make lint` will run golint (install via `go get github.com/golang/lint/golint`) - -## Long term goals - -1.

You pass in an instance of this when you start, and it will be passed to every action when it executes. The actions may mutate this context. - -For example, consider a database library, once you open a database handle, you need to use it inside of the other actions. So you might use a structure like: - -``` -type context struct { - db *DB -} -``` - -### smat.State - -A state represents a state that your application/library can be in, and the probabilities thats certain actions should be taken. - -For example, consider a database library, in a state where the database is open, there many things you can do. Let's consider just two right now, you can set a value, or you can delete a value. - -``` -func dbOpen(next byte) smat.ActionID { - return smat.PercentExecute(next, - smat.PercentAction{50, setValue}, - smat.PercentAction{50, deleteValue}, - ) -} -``` - -This says that in the open state, there are two valid actions, 50% of the time you should set a value and 50% of the time you should delete a value. **NOTE**: these percentages are just for characterizing the test workload. - -### smat.Action - -Actions are functions that do some work, optionally mutate the context, and indicate the next state to transition to. Below we see an example action to set value in a database. - -``` -func setValueFunc(ctx smat.Context) (next smat.State, err error) { - // type assert to our custom context type - context := ctx.(*context) - // perform the operation - err = context.db.Set("k", "v") - if err != nil { - return nil, err - } - // return the new state - return dbOpen, nil -} -``` - -### smat.ActionID and smat.ActionMap - -Actions are just functions, and since we can't compare functions in Go, we need to introduce an external identifier for them. This allows us to build a bi-directional mapping which we'll take advantage of later. - -``` -const ( - setup smat.ActionID = iota - teardown - setValue - deleteValue -) - -var actionMap = smat.ActionMap{ - setup: setupFunc, - teardown: teardownFunc, - setValue: setValueFunc, - deleteValue: deleteValueFunc, -} -``` - -### smat.ActionSeq - -A common way that many users think about a library is as a sequence of actions to be performed. Using the ActionID's that we've already seen we can build up sequences of operations. - -``` - actionSeq := smat.ActionSeq{ - open, - setValue, - setValue, - setValue, - } -``` - -Notice that we build these actions using the constants we defined above, and because of this we can have a bi-directional mapping between a stream of bytes (driving the state machine) and a sequence of actions to be performed. - -## Fuzzing - -We've built a lot of pieces, lets wire it up to go-fuzz. - -``` -func Fuzz(data []byte) int { - return smat.Fuzz(&context{}, setup, teardown, actionMap, data) -} -``` - -* The first argument is an instance of context structure. -* The second argument is the ActionID of our setup function. The setup function does not consume any of the input stream and is used to initialize the context and determine the start state. -* The third argument is the teardown function. This will be called unconditionally to clean up any resources associated with the test. -* The fourth argument is the actionMap which maps all ActionIDs to Actions. -* The fifth argument is the data passed in from the go-fuzz application. - -### Generating Initial go-fuzz Corpus - -Earlier we mentioned the bi-directional mapping between Actions and the byte stream driving the state machine. We can now leverage this to build the inital go-fuzz corpus. - -Using the `ActinSeq`s we learned about earlier we can build up a list of them as: - - var actionSeqs = []smat.ActionSeq{...} - -Then, we can write them out to disk using: - -``` -for i, actionSeq := range actionSeqs { - byteSequence, err := actionSeq.ByteEncoding(&context{}, setup, teardown, actionMap) - if err != nil { - // handle error - } - os.MkdirAll("workdir/corpus", 0700) - ioutil.WriteFile(fmt.Sprintf("workdir/corpus/%d", i), byteSequence, 0600) -} -``` - -You can then either put this into a test case or a main application depending on your needs. - -## Longevity Testing - -Fuzzing is great, but most of your corpus is likely to be shorter meaningful sequences. And go-fuzz works to find shortest sequences that cause problems, but sometimes you actually want to explore longer sequences that appear to go-fuzz as not triggering additional code coverage. - -For these cases we have another helper you can use: - -``` - Longevity(ctx, setup, teardown, actionMap, 0, closeChan) -``` - -The first four arguments are the same, the last two are: -* random seed used to ensure repeatable tests -* closeChan (chan struct{}) - close this channel if you want the function to stop and return ErrClosed, otherwise it will run forever - -## Examples - -See the examples directory for a working example that tests some BoltDB functionality. diff --git a/vendor/github.com/msteinert/pam/README.md b/vendor/github.com/msteinert/pam/README.md deleted file mode 100644 index 66b3820662..0000000000 --- a/vendor/github.com/msteinert/pam/README.md +++ /dev/null @@ -1,30 +0,0 @@ -[![Build Status](https://travis-ci.org/msteinert/pam.svg?branch=master)](https://travis-ci.org/msteinert/pam) -[![GoDoc](https://godoc.org/github.com/msteinert/pam?status.svg)](http://godoc.org/github.com/msteinert/pam) -[![Coverage Status](https://coveralls.io/repos/msteinert/pam/badge.svg?branch=master)](https://coveralls.io/r/msteinert/pam?branch=master) -[![Go Report Card](http://goreportcard.com/badge/msteinert/pam)](http://goreportcard.com/report/msteinert/pam) - -# Go PAM - -This is a Go wrapper for the PAM application API. - -## Testing - -To run the full suite, the tests must be run as the root user.
