[mv3] Add support for procedural cosmetic filtering 2022-09-24 11:33:04 -04:00
Raymond Hill a71b71e4c8
New cosmetic filter parser using CSSTree library
The new parser no longer uses the browser DOM to validate
that a cosmetic filter is valid or not, this is now done
through a JS library, CSSTree.

This means filter list authors will have to be more careful
to ensure that a cosmetic filter is really valid, as there is
no more guarantee that a cosmetic filter which works for a
given browser/version will still work properly on another
browser, or different version of the same browser.

This change has become necessary because of many reasons,
one of them being the flakiness of the previous parser as
exposed by many issues lately:

- https://github.com/uBlockOrigin/uBlock-issues/issues/2262
- https://github.com/uBlockOrigin/uBlock-issues/issues/2228

The new parser introduces breaking changes, there was no way
to do otherwise. Some current procedural cosmetic filters will
be shown as invalid with this change. This occurs because the
CSSTree library gets confused with some syntax which was
previously allowed by the previous parser because it was more
permissive.

Mainly the issue is with the arguments passed to some procedural
cosmetic filters, and these issues can be solved as follow:

Use quotes around the argument. You can use either single or
double-quotes, whichever is most convenient. If your argument
contains a single quote, use double-quotes, and vice versa.

Additionally, try to escape a quote inside an argument using
backslash. THis may work, but if not, use quotes around the
argument.

When the parser encounter quotes around an argument, it will
discard them before trying to process the argument, same with
escaped quotes inside the argument. Examples:

Breakage:

    ...##^script:has-text(toscr')

Fix:

    ...##^script:has-text(toscr\')

Breakage:

    ...##:xpath(//*[contains(text(),"VPN")]):upward(2)

Fix:

    ...##:xpath('//*[contains(text(),"VPN")]'):upward(2)

There are not many filters which break in the default set of
filter lists, so this should be workable for default lists.

Unfortunately those fixes will break the filter for previous
versions of uBO since these to not deal with quoted argument.
In such case, it may be necessary to keep the previous filter,
which will be discarded as broken on newer version of uBO.

THis was a necessary change as the old parser was becoming
more and more flaky after being constantly patched for new
cases arising, The new parser should be far more robust and
stay robist through expanding procedural cosmetic filter
syntax.

Additionally, in the MV3 version, filters are pre-compiled
using a Nodejs script, i.e. outside the browser, so validating
cosmetic filters using a live DOM no longer made sense.

This new parser will have to be tested throughly before stable
release.

[mv3] Add scriptlet support; improve reliability of cosmetic filtering
First iteration of adding scriptlet support. As with cosmetic
filtering, scriptlet niijection occurs only on sites for which
uBO Lite was granted extended permissions.

At the moment, only three scriptlets are supported:
- abort-current-script
- json-prune
- set-constant

More will be added in the future.

[mv3] Add support for specific cosmetic filtering
Specific plain CSS cosmetic filters are now supported.

Cosmetic filtering will occur only after the user explicitly
grant uBO extended permissions for a given site, so that it
can inject CSS on the site.

A new button in the popup panel allows a user to grant/revoke
extended permissions to/from uBO Lite for the current site.

More capabilities will be carefully added for when extended
permissions are granted on a site, so specific cosmetic
filtering through plain CSS is the first implemented capability.

Generic and procedural cosmetic filtering is not implemented.

The current implementation for plain CSS cosmetic filters is
through declarative content injection, which does not require
the service worker to be alive, the browser takes care to
inject the cosmetic filters.

However declarative CSS injection does not support user
styles, so the injected cosmetic filters are "weak". I consider
this is a browser issue, since user styles are supported by
Chromium, there is just no way in the API to specify user
styles for the injected content.

Also:
- Fixed dark theme issues
- Added Steven Black's hosts file

Keep in mind all this is very experimental and implementation
details in this release may (will) greatly change in the future.

Add experimental mv3 version
This create a separate Chromium extension, named
"uBO Minus (MV3)".

This experimental mv3 version supports only the blocking of
network requests through the declarativeNetRequest API, so as
to abide by the stated MV3 philosophy of not requiring broad
"read/modify data" permission. Accordingly, the extension
should not trigger the warning at installation time:

    Read and change all your data on all websites

The consequences of being permission-less are the following:

- No cosmetic filtering (##)
- No scriptlet injection (##+js)
- No redirect= filters
- No csp= filters
- No removeparam= filters

At this point there is no popup panel or options pages.

The default filterset correspond to the default filterset of
uBO proper:

Listset for 'default':
  https://ublockorigin.github.io/uAssets/filters/badware.txt
  https://ublockorigin.github.io/uAssets/filters/filters.txt
  https://ublockorigin.github.io/uAssets/filters/filters-2020.txt
  https://ublockorigin.github.io/uAssets/filters/filters-2021.txt
  https://ublockorigin.github.io/uAssets/filters/filters-2022.txt

  https://malware-filter.gitlab.io/malware-filter/urlhaus-filter-online.txt
  https://pgl.yoyo.org/adservers/serverlist.php?hostformat=hosts&showintro=1&mimetype=plaintext

The result of the conversion of the filters in all these
filter lists is as follow:

Ruleset size for 'default': 22245
  Good: 21408
  Maybe good (regexes): 127
  redirect-rule= (discarded): 458
  csp= (discarded): 85
  removeparams= (discarded): 22
  Unsupported: 145

The fact that the number of DNR rules are far lower than the
number of network filters reported in uBO comes from the fact
that lists-to-rulesets converter does its best to coallesce
filters into minimal set of rules. Notably, the DNR's
requestDomains condition property allows to create a single
DNR rule out of all pure hostname-based filters.

Regex-based rules are dynamically added at launch time since
they must be validated as valid DNR regexes through
isRegexSupported() API call.

At this point I consider being permission-less the limiting
factor: if broad "read/modify data" permission is to be used,
than there is not much point for an MV3 version over MV2, just
use the MV2 version if you want to benefit all the features
which can't be implemented without broad "read/modify data"
permission.

To locally build the MV3 extension:

    make mv3

Then load the resulting extension directory in the browser
using the "Load unpacked" button.

From now on there will be a uBlock0.mv3.zip package available
in each release.
