Add a public method AbuseFilterChangesList that updates a map of RC IDs.
I don't particularly like this approach, but I don't like the whole
ChangesList situation either, so this should be fine for the time being.
Bug: T381836
Change-Id: I0100ed64472de67cf4559f63f2c39eb2f882e0f5
Why:
T367390 hid protected filters from users who didn't have the right to see them
because users with access to private filters also had access to search against
filters and were inadvertantly allowed to search against protected filters regardless
of whether or not they had the right to see them.
Now, in order to be consistent with how AbuseFilter displays private filters, reveal
protected filters to all users but continue to restrict access to their details.
What:
- Only hide protected filters when a user runs a search and doesn't have permission
to access them.
Bug: T381470
Change-Id: I2acb7e066885f6da18b29876c21c5d7d199b9886
Why:
* Protected variables were introduced to support temporary accounts
so that temporary users could be filtered based on their IP address.
* Filters that use protected variables are protected in order to
preserve privacy. This can't be undone.
* The current workflow for protecting filters is to have a 'protect'
checkbox that can be checked for any filter, even one without
protected variables, to the discretion of the editor. This has
led to mistakes (see T37765).
What:
* Do not show the 'protect' checkbox on the form by default. Instead,
show it when saving a filter with protected variables, after form
submission. The user must check it to save the filter.
* Still show the checkbox in a disabled state with a warning message
if a filter is already protected, so that the editor can easily see
it is protected.
Bug: T377765
Change-Id: Ie5c94ac1399860ccdca4482508dd37ff07309764
Why:
* For improvements to the protected filters workflow (T377765),
a checkbox needs to be displayed conditionally on the status
of a previously submitted form.
What:
* Pass a status object into ::buildFilterEditor, and build the
HTML for any warnings or errors in that function, instead of
first building the HTML and passing it.
* This also allows more than one error and/or warning to be
shown if present, though this may not happen in practice yet.

Conditional set of variable is not easy to read.
Instead set the variable to null before try/catch
Reported by a new phan plugin (2efea9f989)
This bypass a false positive from phan (T378271)
Change-Id: I037efe8465747b8c915405f38546fc1ea4405a03
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

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
- Check for the preference and the view right for logs that reveal
protected variables on:
+ AbuseFilterViewExamine
+ SpecialAbuseLog
+ QueryAbuseLog

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.

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.

- Allow testing "move_redir" page moves.
- Allow testing "create2" and "byemail" account creations.
- Add remarks in the code that "autocreate" account creations
cannot be tested since they are not in the recent changes.

Some features restrict access when filters are private. These features
should treat protected filters similarly.
If the user doesn't have view rights for protected filters:
- Disallow viewing of logs generated by protected filters
- Disallow querying of matches against protected filters

Any filter using protected variables must be marked as protected via
the a checkbox on the filter edit form. This checkbox should not be
visible to users without the right to use protected variables.
Bug: T364485

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

Special:AbuseFilter/history/<ID>, show the permission error
message for protected filters.
Before this commit, the error message for hidden filters is
used instead, even if the filter is not hidden.

- Add a basic checkbox on the filter edit page that must be checked if a
filter uses a protected variable to ensure that the user is aware that
their filter will also become protected

Some exposed variables (eg. `user_ip`) used in filters are sensitive
and need to only be available to restricted groups of users.
Back-end changes:
- Add `AbuseFilterProtectedVariables` which defines what variables are
protected by the new right `abusefilter-access-protected-vars`
- Add the concept of a `protected` variable, the use of which will
denote the entire filter as protected via a flag on `af_hidden`
New UX features:
- Display changes to the protected status of filters on history and diff
pages
- Check for protected variables and the right to see them in filter
validation and don't allow a filter to be saved if it uses a variable
that the user doesn't have access to
- Check for the right to view protected variables before allowing access
and edits to existing filters that use them

Protected variables will cause the filter using them to become
protected as well. `af_hidden` can be used to track this flag,
as it is a TINYINT and can be converted into a bitmask with no
schema changes.
This is not a backwards-compatible change, as now all checks must
check the `hidden` flag specifically or otherwise will be cast to
true if any flag is set.
To support this change:
- "hidden" is considered a flag set in the `af_hidden`. This is a
change in concept with no need for updates to the column values,
as there is currently only one flag in the bitmask.
- `Flag`s store the bitmask as well as the state of single flags
and can return either.
- Any checks against the `af_hidden` value no longer check a
boolean value and instead now check the `hidden` flag value.

After temporary accounts are enabled, filters that rely on an ip
in the `user_name` will fail (eg. `ip_in_range` and `ip_in_ranges`).
To keep these filters working:
- Expose the IP through another variable, `user_unnamed_ip`, that can be
used instead of `user_name`.
- The variable is scoped to only reveal the IPs of temporary accounts
and un-logged in users.
- Wikis that don't have temporary accounts enabled will be able to see
this variable but it won't provide information that `user_name`
wasn't already providing
- Introduce the concept of transforming variable values before writing
to the blob store and after retrieval, as IPs need to be deleted from
the logs eventually and can't be stored as-is in the amend-only blob
store

This issue exists ever since this code was added in 2009. Note how
this element is invisible anyway. The non-breaking space is never
seen. The purpose of this element is to act as a container for a
debug result that will be put into this container via JavaScript.
I confirmed this still works fine without the placeholder character
being there.
The problem here is that this HTML entity is double escaped because
of the element() function. That would need to be a rawElement() call
or we can just remove it.

MediaWiki core change Icb8822def9ce56f42ff52a8e469bb08d61d576c6
improved the type hints for OutputPage::addWikiMsg(), resulting in
two new errors:
* AbuseFilterViewEdit.php: False positive, update suppression
to include new error code.
* SpecialAbuseLog.php: Genuine bug, the return value of
Status::getErrors() can't be used directly as a message key.
I have another change pending that introduces a nicer way
to do this: Ibc4ce11594cf36ce7b2495d2636ee080d3443b04,
but in the meantime, make do with the available getters.
