Why:
- For account creations and account autocreations, the user_name
property is deliberately unset, to avoid displaying the IP address of
an unregistered user. Instead, `accountname` is set with the newly
created account name
- For logging that someone has seen a protected variable value, we need
to record the username that was seen
What:
- Use `accountname` as a fallback in case `user_name` is not set, when
logging protected variable access
- Update tests to cover this case.

Like CheckUser, AbuseFilter should also log when specific protected
logs are viewed.
- Add support for debouncing logs to reduce log spam
- Log when AbuseFilterViewExamine with protected variables available
is accessed
- Log when SpecialAbuseLog with protected variables available is
accessed
- Log when QueryAbuseLog with protected variables available is accessed

CVE-2024-PENDING
Why:
* The 'abusefiltercheckmatch' API allows callers to match
arbitary filter conditions against existing AbuseFilter logs
* The API does not check if the performer has the ability to
see the log details for the given filter, so can allow a user
to bypass hidden and protected visibility settings.
What:
* Call AbuseFilterPermissionManager::canSeeLogDetailsForFilter
before attempting to match a filter against a given AbuseFilter
log.
* Add a test to verify that this security fix works.

- Fix an issue where if a user didn't have view permissions they could
get the preference check error (a preference they wouldn't have) on
SpecialAbuseLog
- Fix an issue where the `change-access` hadn't been updated to the used
disabled/enabled log types
- Fix an issue where a ProtectedVarsAccessLoggerTest test wasn't
correctly using the data provider data
- Improve naming since ProtectedVarsAccessLogger exists in its own test
file instead of being a subset of tests on AbuseLoggerTest

Similar to how CheckUser logs access to IP information about temporary
accounts, AbuseFilter needs to log whenever protected variables are
accessed.
- Implement ProtectedVarsAccessLogger which handles access logging
- Log whenever a user changes their ability to access protected
variables via Special:Preferences

Users need to enable a preference before gaining access to the IPs
from `user_unnamed_ip`, a protected variable.
- Add a preference that the user can check to toggle their access

+ AbuseFilterViewExamine

Why:
* SearchFilters.php allows the caller to search by a regex that
is applied to the pattern.
* This script can be expanded to allow callers to specify what
consequence should be associated with the filters that are
outputted.
What:
* Add a 'consequence' option to the SearchFilters.php maintenance
script, which is applied through a LIKE query on the
af_actions column.
** This can be specified with or without the pattern option.
** Instead of making pattern required, the script now requires
that one of consequence or pattern is provided.
* Expand the tests for the script for this new code, along with
using the new ::expectCallToFatalError method to be able to
test previously untestable code.

A filter using a protected variable can be loaded via filter id
using testing tools even though the user might not have the right
to view protected variables. This can potentially leak PII and as
such, testing tools should check for the right before allowing
protected filters to be seen.
- Unload a filter asap if it uses protected variables and the
requestor doesn't have viewing rights. This:
+ disallows loading of existing protected filters on page load
+ disallows testing against rules that use protected variables
+ disallows subsequent requests for protected filters (via API)
There is a known bug (see T369620) where no user feedback is
provided if an API request for a filter returns no result (typically
when no filter matches the requested id). This commit adds another
pathway to that bug (the filter exists but is protected and not
returned by the API) but does not update this UI/UX.

- Loosen the check for the status error message such that 'captcha-edit'
and 'captcha-edit-fail' are both valid; we can revert this after

Search is restricted to users with the right to view private variables
but not necessarily the right to view protected variables. Users who
don't have the right to view protected variables shouldn't be able to
search against protected variables, as this might leak the PII.
- Filter out filters using protected variables in search results
if the user doesn't have the right to view protected variables

- Rename `$hidden` to `$privacyLevel` in Flags::__construct for
consistency with other places.
- Rename `shouldProtectFilter` and simplify its return value to always
be an array, since that's how it's currently used. Rename a variable
that is assigned the return value of this method.
- Add a missing message key to a list of dynamic message keys.
- Rename a property from 'hidden' to 'privacy' in FilterStoreTest for
consistency. Add a test for removing the protected flag.
- Update old comment referencing `filterHidden`; the method was removed
in I40b8c8452d9df.
- Use ISQLPlatform::bitAnd() instead of manual SQL in
AbuseFilterHistoryPager.
- Update mysterious reference to "formatRow" in SpecialAbuseLog.
- Update other references to the very same method in two other places,
this time credited as "SpecialAbuseLog".
- Add type hints to a few methods; this not only helps with type safety,
but it also allows PHPUnit to automatically use the proper type in
mocks.

`canSeeLogDetails` should also be checked when a filter is protected, as
it is the base right for being able to see abuselog entries. With this
in mind, check that immediately at the beginning of the method, instead
of repeating calls. Also merge the conditionals, and return early when a
permission check fails.
Move a test up so that it comes immediately after its data provider, and
add test cases for a few combinations of rights.

Why:
- The previous attempt to integrate AbuseFilter with ConfirmEdit set
a flag on the request object
(I110a5f5321649dcf85993a0c209ab70b9886057c) didn't work in WMF
production because in WMF, we load ConfirmEdit first, followed by
AbuseFilter. Therefore any flag set in an AbuseFilter hook is ignored
by ConfirmEdit
What:
- Remove implementation of ConfirmEditTriggersCaptchaHook, as this does
not work when AbuseFilter is loaded after ConfirmEdit.
- Repurpose onConfirmEditTriggersCaptcha to handle non-edit actions only
- Implement the EditFilterMergedContent hook and call SimpleCaptcha's
public confirmEditMerged method if CaptchaConsequence has specified
that a CAPTCHA should be displayed, and if the CAPTCHA has not already
been solved

In some cases, evaluation short-circuits when getting a list of
used variables resulting in an incomplete array of variables. This
subsequently causes issues when using those arrays for validation

The UI/UX for acknowledging a filter will be protected/is protected
could be clearer. The checkbox implemented currently doesn't make
it clear that the acknowledgement is mandatory and filters that are
already protected allow for the checkbox to be unchecked even though
that doesn't reflect that the filter cannot be unprotected.
- Update copy for the protected filter acknowledgement to make it clear
that it's a mandatory acknowledgement, not an optional one
- Update copy for the error that shows when a filter that should be
protected doesn't have the acknowledgement checked
- When a filter is already protected, disable the acknowledgement
checkbox to indicate this is not mutable
