This breaks uBOL -- unclear error message but disabling rulesets
eventually unbreak the extension, thus possibly a case of going
over the rule limit as a result of transposition.
The `requestDomains` issue will have to wait for the official
Safari fix.
As discussed internally.
The custom DNR rule count will be reported only when it's not zero,
and the count is only for effective DNR rules, i.e. it will not be
reported if "Developer mode" is not enabled.
This feature is hidden behind the "Developer mode" setting in
the dashboard. When "Developer mode" is enabled, a tab named
"Develop" will become available in the dashboard. This tab is
meant to contain tools for technical users.
At the moment, the "Develop" pane allows to create custom DNR
rules through a (CodeMirror-based) editor.
For the sake of convenience, the DNR rule must be entered in
YAML-like format. The format is not really full compliant YAML,
just YAML-like, and very strict in order to ensure the parser
stays simple enough.
Lines starting with `#` are comments and will be ignored by the
parser.
Any line which do not match the parser's expectation will be
marked as invalid, and the whole DNR rule containing such invalid
lines will be discarded.
There must not be empty lines inside a rule definition.
Each DNR rule must be separated with a `---` line, which is
known as a YAML document separator.
String values must not be quoted, otherwise the quotes will be
considered part of the value. There is one exception: `''` will
be parsed as "an empty string".
The editor will attempt to auto-complete known DNR keywords. That
feature will improve over time.
Though the parser will identify some errors, not all invalid DNR
rules are currently identified by the parser, and these will be
reported when the rules are registered through the DNR API. Better
identifying invalid DNR rules at edit time will improve over time.
The editor will report `regexFilter` values which are not
supported by the DNR engine on the current platform.
The editor reacts to instances of `regexFilter: ...` to report
whether a regex value is supported. This means you can test for
a regex value by using `# regexFilter: ...` so that you do not
have to create an actual DNR rules just for the sake of testing.
Custom DNR rules can be exported into a JSON file (a format
known by the DNR API as a "static ruleset").
JSON-based ruleset can be imported, the content will be converted
to YAML-like syntax.
The editor will attempt to convert to YAML pasted content which
can be JSON-parsed. It's possible to paste partially or wholly
JSON-based rulesets.
When disabling "Developer mode", all custom DNR rules will be
unregistered from the DNR API. The DNR rules content will be left
intact in such case. Existing DNR rules will be registered into
the DNR API when re-enabling "Developer mode".
Administrators can prevent "Developer mode" from being enabled
by adding `develop` token to `disabledFeatures` setting.

The main motivation is to give list maintainers a tool to assist
with resolving filter issues. Custom DNR rules can assist in
crafting and validating filters meant to work with uBOL.
A secondary motivation is to provide technical users the ability
to further customize their content blocker.
More conveniences will be added over time, this is a first version.

The `header=` option will be converted into DNR's `responseHeaders`
condition.
There will be an attempt to convert regex-based values into DNR-
compatible syntax. Not all regex-based patterns can be converted to
use DNR's patterns with `*` and `?` special characters.
The implementation of `header=` option in uBO has been revisited to
improve compatibility with DNR syntax to minimize burden for list
maintainers when creating `header=` filters compatible with both
uBO and uBOL.
The changes:
- Header names are now case-insensitive by default
- Occurrences of `*` in non-regex-based header values now mean
"matches any number of characters"
- Occurrences of `?` in non-regex-based header values now mean
"matches zero or one character"
At time of commit, and as per MDN, only Chromium-based browsers
currently support filtering on repsonse headers:
https://developer.mozilla.org/docs/Mozilla/Add-ons/WebExtensions/API/declarativeNetRequest/HeaderInfo
Also as per MDN, Chromium 121-127 silently ignore the `responseHeaders`
condition, potentially causing undue blocking of network requests.
Currently uBOL support Chromium 122 and later, meaning we need to mind
potential false positives in Chromium 122-127 for filters using
`header=` option.

Stable Safari is known to not block certain network requests due to
the current state of the DNR engine in Safari. The warning is to
ensure volunteers are not burdened by issues originating from the
browser.
Eventually Safari's DNR implementation will catch up with the
specification, at which time the warning will be removed.
This is a first step to integrate CodeMirror6 into the project.
As a side effect, this should take care of:
https://github.com/uBlockOrigin/uBOL-home/issues/297
Though most likely the list of no-filtering websites will probably
move to its own pane as in uBO in some future.
Most of the time the URL doesn't change and just forcing a reload
of the page is sufficient. When a document is strict-blocked, the
URL must be updated however.

onMessage() is now a listener installed synchrnously when uBOL
executes, so no longer need to deal with failure to send messages.

Setting name: "defaultFiltering"
Type: string
Valid values: "none", "basic", "optimal", "complete"
Additionally, fix default "basic" mode toggling back to "optimal"
upon extension restart when uBOL has broad host permissions. The
default mode will toggle automatically only when there is a change
in broad host permissions status.
Related issue:
https://github.com/uBlockOrigin/uBOL-home/issues/326
uBOL now asks broad host permissions by default. Users can still
choose narrow host permissions by using their browser's controls
for this.
For instance in Chromium, those host permissions controls are found
in the "Site access" section in the detailed view of an extension.
One can set "Site access" to "On click" to revoke broad host
permissions, and grant host permissions to only specific site.
In such mode, uBOL will still block through the DNR API, but no
cosmetic or scriptlet filtering will occurs, as these requires
permission to "read and change data" on websites for which higher
filtering mode is desired.
Some browsers do not automatically grant broad host permissions
even when an extension asks for broad permissions at install time,
and going forward all browsers will likely adopt this approach, and
thus it no longer made sense for uBOL to default to no broad hosts
permissions at install time, especially given this leads to issues
with no solution -- issues solved with the new approach (e.g. like
the ability to deploy uBOL in Optimal mode by default).
Support for paths allows to narrow down specific static extended
filters to specific webpages on a given site.
Examples of usage:
example.com/toto##h1
/example\.com\/toto\d+/#@#h1
Call to postMessage was failing in the zapper when using `use_dynamic_url` in
manifest. Manually overwriting the per-session dynamic hostname with the real
extension id fixes this.
A bad test prevented the "no filtering" by default mode to not take
effect immediately when activated while no site had yet been set to
"no filtering". It would however take effect as soon as a specific
site would be excluded from "no filtering".
`generichide` option is implicitly enforced on all sites unless an
exception overrides `generichide`. Though rare, sometimes a
`generichide` exception needs to be overridden so that generic
cosmetic filtering is made possible on a specific site.
This commit is to add support for restoring generic cosmetic
filtering on sites which were excluded through a `generichide`
exception.
Concretely, this is needed to ensure the test suite can properly
verify that generic cosmetic filtering is working when the
filtering mode is set to "complete":
