Enable forbidigo linter (#24278) Enable [forbidigo](https://github.com/ashanbrown/forbidigo) linter which forbids print statements. Will check how to integrate this with the smallest impact possible, so a few `nolint` comments will likely be required. Plan is to just go through the issues and either: - Remove the print if it is nonsensical - Add a `//nolint` directive if it makes sense I don't plan on investigating the individual issues any further. <details> <summary>Initial Lint Results</summary> ``` modules/log/event.go:348:6: use of `fmt.Println` forbidden by pattern `^(fmt\.Print(|f|ln)|print|println)$` (forbidigo) fmt.Println(err) ^ modules/log/event.go:382:6: use of `fmt.Println` forbidden by pattern `^(fmt\.Print(|f|ln)|print|println)$` (forbidigo) fmt.Println(err) ^ modules/queue/unique_queue_disk_channel_test.go:20:2: use of `fmt.Printf` forbidden by pattern `^(fmt\.Print(|f|ln)|print|println)$` (forbidigo) fmt.Printf("TempDir %s\n", tmpDir) ^ contrib/backport/backport.go:168:2: use of `fmt.Printf` forbidden by pattern `^(fmt\.Print(|f|ln)|print|println)$` (forbidigo) fmt.Printf("* Backporting %s to %s as %s\n", pr, localReleaseBranch, backportBranch) ^ contrib/backport/backport.go:216:4: use of `fmt.Printf` forbidden by pattern `^(fmt\.Print(|f|ln)|print|println)$` (forbidigo) fmt.Printf("* Navigate to %s to open PR\n", url) ^ contrib/backport/backport.go:223:2: use of `fmt.Printf` forbidden by pattern `^(fmt\.Print(|f|ln)|print|println)$` (forbidigo) fmt.Printf("* `xdg-open %s`\n", url) ^ contrib/backport/backport.go:233:2: use of `fmt.Printf` forbidden by pattern `^(fmt\.Print(|f|ln)|print|println)$` (forbidigo) fmt.Printf("* `git push -u %s %s`\n", remote, backportBranch) ^ contrib/backport/backport.go:243:2: use of `fmt.Printf` forbidden by pattern `^(fmt\.Print(|f|ln)|print|println)$` (forbidigo) fmt.Printf("* Amending commit to prepend `Backport #%s` to body\n", pr) ^ contrib/backport/backport.go:272:3: use of `fmt.Println` forbidden by pattern `^(fmt\.Print(|f|ln)|print|println)$` (forbidigo) fmt.Println("* Attempting git cherry-pick --continue") ^ contrib/backport/backport.go:281:2: use of `fmt.Printf` forbidden by pattern `^(fmt\.Print(|f|ln)|print|println)$` (forbidigo) fmt.Printf("* Attempting git cherry-pick %s\n", sha) ^ contrib/backport/backport.go:297:2: use of `fmt.Printf` forbidden by pattern `^(fmt\.Print(|f|ln)|print|println)$` (forbidigo) fmt.Printf("* Current branch is %s\n", currentBranch) ^ contrib/backport/backport.go:299:3: use of `fmt.Printf` forbidden by pattern `^(fmt\.Print(|f|ln)|print|println)$` (forbidigo) fmt.Printf("* Current branch is %s - not checking out\n", currentBranch) ^ contrib/backport/backport.go:304:3: use of `fmt.Printf` forbidden by pattern `^(fmt\.Print(|f|ln)|print|println)$` (forbidigo) fmt.Printf("* Branch %s already exists.

Rewrite queue (#24505) # ⚠️ Breaking Many deprecated queue config options are removed (actually, they should have been removed in 1.18/1.19). If you see the fatal message when starting Gitea: "Please update your app.ini to remove deprecated config options", please follow the error messages to remove these options from your app.ini. Example: ``` 2023/05/06 19:39:22 [E] Removed queue option: `[indexer].ISSUE_INDEXER_QUEUE_TYPE`. Use new options in `[queue.issue_indexer]` 2023/05/06 19:39:22 [E] Removed queue option: `[indexer].UPDATE_BUFFER_LEN`. Use new options in `[queue.issue_indexer]` 2023/05/06 19:39:22 [F] Please update your app.ini to remove deprecated config options ``` Many options in `[queue]` are are dropped, including: `WRAP_IF_NECESSARY`, `MAX_ATTEMPTS`, `TIMEOUT`, `WORKERS`, `BLOCK_TIMEOUT`, `BOOST_TIMEOUT`, `BOOST_WORKERS`, they can be removed from app.ini. # The problem The old queue package has some legacy problems: * complexity: I doubt few people could tell how it works. * maintainability: Too many channels and mutex/cond are mixed together, too many different structs/interfaces depends each other. * stability: due to the complexity & maintainability, sometimes there are strange bugs and difficult to debug, and some code doesn't have test (indeed some code is difficult to test because a lot of things are mixed together). * general applicability: although it is called "queue", its behavior is not a well-known queue. * scalability: it doesn't seem easy to make it work with a cluster without breaking its behaviors. It came from some very old code to "avoid breaking", however, its technical debt is too heavy now. It's a good time to introduce a better "queue" package. # The new queue package It keeps using old config and concept as much as possible. * It only contains two major kinds of concepts: * The "base queue": channel, levelqueue, redis * They have the same abstraction, the same interface, and they are tested by the same testing code. * The "WokerPoolQueue", it uses the "base queue" to provide "worker pool" function, calls the "handler" to process the data in the base queue. * The new code doesn't do "PushBack" * Think about a queue with many workers, the "PushBack" can't guarantee the order for re-queued unhandled items, so in new code it just does "normal push" * The new code doesn't do "pause/resume" * The "pause/resume" was designed to handle some handler's failure: eg: document indexer (elasticsearch) is down * If a queue is paused for long time, either the producers blocks or the new items are dropped. * The new code doesn't do such "pause/resume" trick, it's not a common queue's behavior and it doesn't help much. * If there are unhandled items, the "push" function just blocks for a few seconds and then re-queue them and retry. * The new code doesn't do "worker booster" * Gitea's queue's handlers are light functions, the cost is only the go-routine, so it doesn't make sense to "boost" them. * The new code only use "max worker number" to limit the concurrent workers. * The new "Push" never blocks forever * Instead of creating more and more blocking goroutines, return an error is more friendly to the server and to the end user. There are more details in code comments: eg: the "Flush" problem, the strange "code.index" hanging problem, the "immediate" queue problem. Almost ready for review. TODO: * [x] add some necessary comments during review * [x] add some more tests if necessary * [x] update documents and config options * [x] test max worker / active worker * [x] re-run the CI tasks to see whether any test is flaky * [x] improve the `handleOldLengthConfiguration` to provide more friendly messages * [x] fine tune default config values (eg: length?) ## Code coverage: ![image](https://user-images.githubusercontent.com/2114189/236620635-55576955-f95d-4810-b12f-879026a3afdf.png)

Rewrite logger system (#24726) ## ⚠️ Breaking The `log.<mode>.<logger>` style config has been dropped. If you used it, please check the new config manual & app.example.ini to make your instance output logs as expected. Although many legacy options still work, it's encouraged to upgrade to the new options. The SMTP logger is deleted because SMTP is not suitable to collect logs. If you have manually configured Gitea log options, please confirm the logger system works as expected after upgrading. ## Description Close #12082 and maybe more log-related issues, resolve some related FIXMEs in old code (which seems unfixable before) Just like rewriting queue #24505 : make code maintainable, clear legacy bugs, and add the ability to support more writers (eg: JSON, structured log) There is a new document (with examples): `logging-config.en-us.md` This PR is safer than the queue rewriting, because it's just for logging, it won't break other logic. ## The old problems The logging system is quite old and difficult to maintain: * Unclear concepts: Logger, NamedLogger, MultiChannelledLogger, SubLogger, EventLogger, WriterLogger etc * Some code is diffuclt to konw whether it is right: `log.DelNamedLogger("console")` vs `log.DelNamedLogger(log.DEFAULT)` vs `log.DelLogger("console")` * The old system heavily depends on ini config system, it's difficult to create new logger for different purpose, and it's very fragile. * The "color" trick is difficult to use and read, many colors are unnecessary, and in the future structured log could help * It's difficult to add other log formats, eg: JSON format * The log outputer doesn't have full control of its goroutine, it's difficult to make outputer have advanced behaviors * The logs could be lost in some cases: eg: no Fatal error when using CLI. * Config options are passed by JSON, which is quite fragile. * INI package makes the KEY in `[log]` section visible in `[log.sub1]` and `[log.sub1.subA]`, this behavior is quite fragile and would cause more unclear problems, and there is no strong requirement to support `log.<mode>.<logger>` syntax. ## The new design See `logger.go` for documents. ## Screenshot <details> ![image](https://github.com/go-gitea/gitea/assets/2114189/4462d713-ba39-41f5-bb08-de912e67e1ff) ![image](https://github.com/go-gitea/gitea/assets/2114189/b188035e-f691-428b-8b2d-ff7b2199b2f9) ![image](https://github.com/go-gitea/gitea/assets/2114189/132e9745-1c3b-4e00-9e0d-15eaea495dee) </details> ## TODO * [x] add some new tests * [x] fix some tests * [x] test some sub-commands (manually ....) --------- Co-authored-by: Jason Song <i@wolfogre.com> Co-authored-by: delvh <dev.lh@web.de> Co-authored-by: Giteabot <teabot@gitea.io>
