This hook is called on every request, even for view actions, hence it's
a hot spot and a potential source of performance issues. We can slightly
optimize it by avoiding a cache lookup if blockautopromote is disabled.
Note: this won't really have an impact on WMF wikis since blockautopromote
is enabled almost everywhere.

The logic about action IDs and the persistent buffer is now encapsulated
inside a single service, which is a step towards getting rid of global
state in the AbuseFilter class, and reducing the responsibilities of the
Runner.
An important change made here is that we now require a LinkTarget rather
than a Title. This removes a dependency on the Title class (a monster
object), makes tests simpler, and denies the need to inject a
TitleFactory. This means living without some bits of context (e.g. we're
no longer using makeTitleSafe to ensure a valid title, and we have to
build a "prefixedtext" manually), but this shouldn't be a problem, given
that the titles are only used to create a cache key: invalid titles are
not a problem, and concatenating namespace + title should always be
sufficient.

This patch addresses two issues observed in WMF production:
- Specifying a search mode without a search pattern would result in a
call to mb_stripos (in AbuseFilterPager) with an empty delimiter,
which triggers a PHP warning. Avoid this by checking that the search
pattern is not the empty string, and unset the search mode if that's
the case.
- Trying to use an invalid search mode would result in an unhandled
LogicException. We have some code in place to check the validity of
the URL parameter, but the relevant code didn't reset the search mode
to null, hence AbuseFilterPager would throw before we can show a
pretty error to the user.

It doesn't make much sense to try to remove implicit groups like 'user'
and '*'. As a matter of fact, these groups are also excluded in
AbuseFilterViewRevert when undoing degroups.

This method was divided into multiple, shorter methods. We now have a
dedicated method for imports, and one for everything else, plus a method
for loading actions. Merged a conditional for when the token didn't
match. Avoid returning Status objects with data inside as it's too
difficult to properly infer types for those.
This is still not perfect, and another round of simplification might be
necessary before this class can be updated to use the upcoming Filter
value objects.

While this might seem a small change, it removes the last remaining
coupling between SpecialAbuseFilter and the *View classes, that were
forming a huge tangle.

Don't create <a> tags without a href. Show a placeholder
message instead of nothing (alternatively, we could create
a new message for each existing one).

The first one is UserGroupManager, used for the 'degroup' action. This
is a simple one-line replacement (repeated twice), and the current code
was already using this service under the hood.
The second one is BlockUser, which is not a one-line change (but still
quite simple). In particular, this allows us to avoid duplication with
core logic when constructing the log entry (this is now done by
BlockUser).

This code was simply caching the AbuseFilter::$tagsToSet property, but
this is not necessary. The only tag that can be buffered during edit
stashing is the conds limit tag. So we just save whether the conds limit
was hit, and apply the tag from a single point afterwards.
Also avoid checking whether 'tag' is enabled as an action, since this tag
should always be added when applicable.
Next step is creating some sort of Watcher service that will do
everything on its own: check whether the limit was hit, save this
information, and tag the action later.

- Depend on a generic IContextSource rather than SpecialAbuseFilter
(lower coupling);
- Inject a LinkRenderer (IContextSource doesn't have a ::getLinkRenderer
method)
- Add a helper method in SpecialAbuseFilter to get the page title, that
can also be used elsewhere (and the name constant can be made private
now)
- Pull down the mFilter property (and rename it to just 'filter') to
classes that actually need it. Some classes didn't need this at all
and the types were different among subclasses
Now the only cause of coupling between the View classes and
SpecialAbuseFilter is the static call in getTitle.

This service should act as a mediator between the AF code and the
permission manager, and it should know what are the permissions required
by each action.

In particular, the interface shouldn't generate links to
"Special:AbuseFilter/history/0" (AbuseFilterHistoryPager::getTitle,
can be seen when visiting "Special:AbuseFilter/history").

PHP is not strongly typed, so it's not a good idea to use scalars of
different types (here it's an integer vs the string 'new') to represent
different possibilities. This can have bad effects when type juggling
occurs, and it's also harder to figure out what the type of the
parameter can be (because a numeric ID might have been passed as a
string). Using integer vs null avoids all of this, and also allows us to
use nullable typehints.
These changes were partly copied from
If981cb35bf19a8469aa6c43c907e107cf8c65bc2 and should help with the
migration to the Filter value objects.

This feature didn't work and even if we fixed it as suggested
in the task, it would still be bogus. For deterministic paging,
the afh_user_text field should be in an index together with
another field(s). But currently it's indexed alone.
By the way, the indexes on abuse_filter_history should be fixed
anyway. Special:AbuseFilter/history also allows filtering by
filter/user which require index on the fields. They are present
but are not composite, so either the sorting is done
inefficiently without an index or there is a fullscan.
Also remove the getIndexField override. TablePager knows best
what value can be used there, we don't really have to override
it.

This was a means to bypass the limitation to filter by
triggered filter (for example, when a group contains
a single filter).

This patch removes the dependency of saveFilter on the ContextSource
kitchen sink. It also removes some unneded dependency, and adds
$originalRow/$originalActions as parameter, rather than hacky properties
in $newRow that are easy to forget. The related test can also be greatly
simplified.
This also introduces a behaviour change: checking $newRow instead of the Request allows us
to account for values normalization done in
AbuseFilterViewEdit::loadRequest, and to also work correctly for imports
(and generally speaking, it makes the method suitable for an
AbuseFilterEdit API module, too).
Next step is moving this method to a service. Some signatures,
indenting, name choices etc. are subpar, but this is just because these
methods are temporary anyway.

The array_filter is likely meant to empty the array if the empty string
was exploded ( `explode( "\n", '' ) === [ '' ]` ). However, it can also
remove other stuff, e.g. the string '0'. An explicit comparison is
easier to read & interpret, marginally faster, and avoids rare but not
impossible edge cases.

Previously, the cached value would depend on the tags
parameter to be updated. The provided value may be
different for each call, so callers may receive
unexpected values.
For example, while core usually calls this with core-defined
hooks, our method AbuseFilter::isAllowedTag calls this
providing an empty array. If core's call happened shortly
after ours and hit cache, its array would be overwritten
with only AbuseFilter's tags, the rest would be lost.
Also do some clean up:
- only call array_filter on explode'd array
- call array_unique on the value, since it's usual that
multiple filters share the same tag
Noticed when thinking about moving this to a service.
