AbuseFilter emulates the storage mechanism also used for page content.
Instead of duplicating the relevant code, AbuseFilter should use the
same BlobStore service also used by RevisionStore.

This is just a temporary location for these two methods. Since they're
used a lot, having them in the AbuseFilter class means that the
dependency graph is unnecessarily complicated. Thus, since these methods
aren't doing much, they were moved to a dedicated class. Future todo is
finding an appropriate location, that might be either as part of another
service, or keep them in a Utilities class, perhaps a single class with
all util methods, rather than a specific class.

The main change is the addition of checkboxes to hide/show multiple
entries at the same time. Also, tweaked some i18n and made the process
return more useful success/error messages.
This patch introduces some technical debt, caused by SpecialAbuseLog and
AbuseLogPager being tightly coupled (which is a pre-existing problem,
but it got worse here).

Move to the latter some methods that make more sense in there. Inject
some more services, don't require a SpecialAbuseLog to be passed in the
constructor.
There are still a couple of static calls, but fixing those would require
factoring more classes out of SpecialAbuseLog (e.g. a service to
determine visibility of AbuseLog entries).
Change-Id: I1b3012ca85bf049a07e0433fc0b357f502c355ad
This is moving code away from SpecialAbuseLog, which is already too big
and has too many purposes. As such, the behaviour is not changed,
including for now bugs that were already present in the old version.

This is achieved by creating a new ParserStatus class. Aside from the

used to differentiate profiling data as part of T231112.

The consequence-taking logic is moved away from AbuseFilterRunner, to
dedicated classes. There's now one class per consequence, encapsulating
everything it needs to take the consequence.
Several interfaces allow customizing different types of consequences.
Every "special check" in AbuseFilter was generalized to use these
interfaces, rather than knowing how to handle each consequence.
Adding more consequences from other extensions will also be easier, and
it should happen via a hook (not a global), returning a class that
implements Consequence. The BCConsequence class was temporarily added
for legacy custom consequences.
A ConsequenceFactory class is added to instantiate consequences; this
would possibly benefit from using ObjectFactory, but it doesn't because
it would also reduce readability (although we might do that in the
future).
These classes are still not covered by unit tests, and this is left to
do for later. The new unit tests should mostly replace
AbuseFilterConsequencesTest. @covers tag were added to keep the status
quo (i.e. code that was considered covered while in AbuseFilterRunner
will still be considered covered), although we'll have to adjust them.

changes:
- The AbuseLog will add a diff link for page creations
- Searching the AbuseLog for impact:saved will include page creations
- We don't have to recreate the WikiPage again in RunVariableGenerator
Also remove an old reference to "bug 31656": that comment was added in
rEABFefecf8b2441ae2f31f924ff33103f5affe5d1d62, which changed
Article::getContent() to Article::getRevision()->getRawText(). Nowadays
we don't even use Article anymore, and that conditional isn't even for
retrieving the page content, so the comment is wrong.
Add logging for when the Title object cannot exist, as this should never
happen in the context of the EditFilterMergedContent hook, and always
create a WikiPage. Some signatures were changed to require a WikiPage
object now, and every caller updated to provide it.

This is a no-op, moving code around, introducing another distinction re
"filtering actions", which now happens in 2 steps:
- The first step only uses "generic" information available by looking
at enabled actions as a "group". This includes keeping only the
longest block, and removing 'disallow' if other blocking actions are
enabled.
- The second step uses information that is only available after having
"partly executed" (named "pre-checked") a consequence. For instance,
we need to pre-check 'throttle' to see if the throttle was hit, and
remove any other actions if not.
Change-Id: I7be5cfaa61e942a06f97ed52f50e9c8c70a120e8
This way we don't have special cases in executeFilterActions, and instead, we execute

This deals with data inconsistencies in buildFilterEditor. Every
property of $row was tested in all 5 scenarios (also using Selenium) to
check when it's set. The result is in the normalizeRow method, which
aims to remove any inconsistencies, so that buildFilterEditor always
receives a "complete" row with all defaults set.
The code in buildFilterEditor is now cleaner (because there are no
isset() checks), and it gives us a unique place where we can set
defaults (rather than partly doing that in
loadRequest/loadFilterData/loadImport, and partly relying on isset).
This will be especially useful when introducing value objects to
represent filters, because now you just have to look at normalizeRow()
to tell which properties are allowed to be missing, and thus what "kind"
of filter object you need (see
I5f33227887c035e301313bbe24d1c1fefb75bc6a).
Additionally, reduce the properties that get passed around during
export/import, and make the selenium test try a roundtrip, rather than
relying on hardcoded data that may get outdated. A future patch will
refactor the import/export code.

The previous code would call getUserGroups again once creating the log

afterwards.

- Add a helper method to output an unrecoverable error, comprising a
button to go back to the filters list;
- Move the token check to attemptSave, so to make the conditionals
easier to read, and group errors together
- Make buildFilterEditor take an HTML parameter for the error, so the
caller can specify whether it's error or warning
- Move the check for non-existing filters out of buildFilterEditor
- Add a bunch of typehints
- Don't set af_throttled and af_hit_count in the empty row template, but
set af_deleted (these are only used in buildFilterEditor)
- Make AbuseFilter::translateFromHistory consistently include the af_global
property (previously it would only be set for global filters; this error
was introduced when first implementing global filters)
- The only user-facing change is that, when trying to use a custom
warning/disallow message on a global filter, this is now considered a
non-fatal error, so we now show the editing interface (and not just an
unrecoverable error).
The next step is resolving the @todo in buildFilterEditor about null
checks.

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.

for loading actions. Merged a conditional for when the token didn't

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.

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

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 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.

Copying my investigation from I8c93e2ae7e7bd4fc561c5e8490ed2feb1ef0edc2:
This code was introduced in 2009, see rEABF0f1eb8db78bfa83ddb93427f39aad619523d8f25:
$display = wfMsg( "abusefilter-action-$action" );
$display = wfEmptyMsg( "abusefilter-action-$action", $display ) ? $action : $display;
And wfEmptyMsg looked like this:
function wfEmptyMsg( $msg, $wfMsgOut ) {
return $wfMsgOut === htmlspecialchars( "<$msg>" );
}
so this made sense. But then, in 2010 (rMWae3ced88e535c7fd046f0ad6f0710cc87f0004ea) the function was changed:
function wfEmptyMsg( $key ) {
global $wgMessageCache;
return $wgMessageCache->get( $key ) === false;
}
without anyone removing the parameter from AbuseFilter.
Finally, in 2012 (rEABF176227e721c9475de2c2163d3b6e20ca4769c406) the usage of wfEmptyMsg was removed, and $display became a parameter to wfMessage().
Long story short, no need to pass that parameter.

Ideally, this might live in MediaWikiIntegrationTestCase. For the

the existing ones (delete file afterwards, more tablesUsed, use the

- Exclude from the coverage report a couple of lines which should

more likely to be spotted.
- Remove an unused method (RCVariableGenerator::newFromID). This denies
the need to maintain and cover it. We also don't want this generator
to act as a factory.

The current code was more of a subpar, temporary solution. However, we
need a stable solution in case more variables will be deprecated in the
future (T213006 fixes the problem for the past deprecation round). So,
instead of setting a hacky property, directly translate all variables
when loading the var dump. This is not only stable, but has a couple
micro-performance advantages:
- Calling getDeprecatedVariables happens only once when loading the
dump, and not every time a variable is accessed
- No checks are needed when retrieving a variable,
because names can always assumed to be new
Some simple benchmarks reveals a runtime reduction of 8-15% compared to
the old code (8% when it had varsVersion = 2, 15% for varsVersion = 1),
which comes at no cost together with increased readability and
stability. It ain't much, but it's honest work.

This will decouple a bit the huge and chaotic tangle of AF classes. Some
boilerplate code for AbuseFilter services is also added with this patch.
Note that this requires injecting a KeywordsManager in
AbuseFilterVariableHolder, or unit tests would fail. This is still
incomplete, and the Manager is only injected in tests, because
VariableHolder still has to be refactored.
The test for the UpdateVarDumps script had to be updated, because
serializing VHs in there was a bad choice. As pointed out in a comment,
the test is likely going to break again once we remove the BC code, but
I hope that we'll be able to remove the test at that point.

While checking a filter, if a variable is not set (e.g. added_lines for
an account creation), the VariableHolder will return a DNULL, rather
than a DUNDEFINED. This means that some filters will resume working, and
the WMF servers will stop getting AF warnings at a rate of 4 millions per
day. This also requires adjusting some tests to reflect the new
behaviour (which is actually the OLD behaviour, that filters had until
last year when we introduced the DUNDEFINED data type). It also requires
adjusting a check in the old parser, but that's not really relevant
because the plan is to remove the old parser before 1.36 is released
(see I0e75f334c7e0dfc1239f2e5f5f7d7452b0bbf29e).

Before the phan upgrade, this was silently choking on null as so falling
back to age since 1970-01-01 (~50 years); since the upgrade, the code is
breaking filters by responding with 0. The approximation of using 2008's
Wikipedia Day is less wrong and more fun (credit to Roan for making this
suggestion).

Instead of having a single loadRequest method (which could end up
loading from the DB...), split it in a DB-only method and a request-only
one. Simplify the logic used to show the filter editor. Show the page
without changes or warnings if the user lost editing rights in the
meanwhile. Avoid two static properties, and pass them in when relevant
instead. Bonus: optimize a query to sort by afh_id instead of afh_timestamp to avoid filesort.
This will allow a subsequent patch to clean the $row object in
loadRequest.

For the new parser, xhgui shows that AbuseFilterParser::getVarValue is
taking up a lot of time; in turn, most of the time spent inside
getVarValue is used to log the use of deprecated variables. Hence, given
that:
- We should keep the new parser performant
- There are tons of deprecated variables out there and they likely
won't be replaced
- Having gazillions of debugLog entries doesn't help
log them only in the cached phase.

AbuseFilterViewEdit does privilege checks based on filter ID,

This will allow people to switch their filters to the new syntax. The
deprecation warning is now more exhaustive, and the info() warning is
kept to ensure that everything proceeds smoothly.
The regex v2 has also been fixed to:
- Consume all the digits/letters on the right (*)
- Have named groups
- Be created dynamically with other constants
(*) The previous version of v2 could complete the match and leave
digits/letters on the right when encountering numbers with the old
syntax, hence dropping support too early. We also cannot use a word
boundary (\b) because that would prevent matching numbers with trailing
dots (e.g. "5.").

Setting 'apiHookResult' results in a "successful" response; if we want

We didn't check if the provided ID was valid. While editing an existing
filter (or creating a new one), we check the ID in SpecialAbuseFilter,
so it's guaranteed to get an integer in ViewEdit, and the case of a
non-existing filter is handled later, in buildFilterEditor.
But for links like Special:AbuseFilter/history/foobarbaz/item/1 (where
"foobarbaz" should be the filter ID), no validation was performed. This
caused a useless query to be carried out on the abuse_filter_history table (which would likely return false), then accessing properties of a non-object ('$row->afh_id'), and we ended up showing filter 1. This was spotted because we actually got notices in production.

This allows a little bit more of abstraction: we can store other data in the

which is still unused). It also adds a few typehints, and specializes
the return value of eval'ing the AST: previously, it was the one of
evalNode, which wasn't guaranteed to be an AFPData. Now we have this

Ensure that the variable isn't set before marking it as DUNDEFINED:
that's only for when we cannot use a default, but if the variable is set
we already have one. Most notably, this fixes conditionals handling: right
now, if you have a conditional with an assignment in both
branches, the variable will be undefined. That's obviously wrong, so
it's fixed in this patch.
Plus: catch only AFPExceptions in a test to avoid unintentionally

This patch includes various fixes to how func arguments are handled in
CachingParser:
- Add a comment about a future improvement of checkSyntax, which we
could limit to try building the AST.
- Having enough args for each function is now also checked when
building the AST. This allows implementing the previous point without
stopping to report notenoughargs at syntaxcheck-time (otherwise it'd be
a runtime error). And it also ensure that we check for the params count
inside skipped branches, e.g. inside if/else: these were already only
discovered at runtime in CachingParser. The old parser is not affected
by this change, because when checking syntax it will always execute
all branches, and at runtime it will skip braces altogether.
- Fix arg count for CachingParser, which previously added a bogus param
in case of a function called without parameters. This was fixed for
the other parser in I484fe2994292970276150d2e417801453339e540, and I
just ported the updated fix. Also note that the CachingParser was
already failing for e.g. `count()`, but instead of complaining about
missing arguments, it failed hard when trying to pass NULL to
evalNode.
- Fixed some tests not to use setExpectedException, which caused the
previous point to remain unnoticed: calling that method prevents the
loop from continuing, and thus only the AbuseFilterParser part was
being executed. The new implementation checks the exception ID and is
thus more future-proof if the i18n message changes.
- Fixed some function names in error reporting for the old parser.
- The arg count is now checked outside of the function handlers, thus
it's no more necessary to call checkEnoughArguments at the beginning
of each handler. This also produces clearer error messages in case of
aliases (e.g. set/set_var).
- Check the args count even if some of the args are DUNDEFINED. This is
much easier now that the check is outside of the handler. This will
make syntax check fail for e.g. `contains_any(added_lines)`.

This was broken in I34c040dbeb3ab01158fb3db22496def6ccaf72d9. I thought
the members of that object were always arrays, but I was wrong.
Plus typehint a few array parameters and make a couple of methods
private since they're only used in this class.

Now it's always wider, and so is the "notes" field. Moreover, the
fallback textarea has the exact same size. Plus removed a parameter
which only made it hard to write a CSS rule for the textarea. Since the
textarea is generated by the same code, and we're always using it for
the same thing (filter syntax, regardless of the final goal), make it
always use the same name.

Problems fixed:
- Don't hardcode duration in the message
- Move duration to a constant
- Fix wrong parameter order for AbuseFilter::blockAutopromote
- Log a warning if we cannot block autopromotion
- Remove the $performer parameter, as it should only and always be the
filter user.

If $parser->parse returns a falsey value (=null), that's because the
filter doesn't have any statement. But that's not a valid reason not to
cache the filter. Hence, return whatever parse() is returning inside the
callback, so that the result is always cached.

encourage people to remove it from tests anymore.

Just like we do for functions, it doesn't really make sense to have
keywords separately, in AFPData.
Change-Id: I208a9b1ce2bd12038e9fbcc515c48d604ec80eb8
This patch keeps the current behaviour for everything (since DUNDEFINED
was always casted to boolean false), but handles the cast at a higher
level instead of relying on what AFPData::castTypes will do. This way
it's easier to spot places where we may get DUNDEFINED, and decide how
to handle them one by one.

from Hooks instead of duplicating the logic.

This allows us to extract yet another static method from the AbuseFilter

case could be Ia5fd4f0b35fcabf045a7b49fa40fa85b72c92544.

This is more complicated than the := operator, because the var name
could be a complicated expression, and we have to handle a function
call. This patch only covers the case where the variable name is a
literal, which is enough for WMF production.

As for all mostly unused consequences, blockautopromote has a couple of
major problems: first, it blocked the status for a random time between 3
and 7 days, which to me makes no sense at all (is it some sort of
casino?), and this patch fixes it to 5 days. Second, nothing was logged,
not the blocking nor the unblocking. Here I'm adding a LogHandler for
two new sub-actions of 'rights' to keep track of both action.

Follow-up I7831f3ed9f7c0656e0e8f77ded049c20eca682ba, really avoid the leak. My addition was pointless because we need DUNDEFINED, not DEMPTY, and I spent way too much time trying to understand what was still wrong.
Still have to get used to these new names...

Parsing wikitext and retrieving its links are operations which we share
with the edit, so that if a filter does that, it won't be done later
upon saving.
Thus, add a static variable to subtract such time and avoid to erroneously log as slow any filter using those variables.

As shown in the coverage reports [0], some empty operand logging lines are covered, but no test should have empty operands. I see one of the cause is skipOverBraces keeping $result as is, even if DEMPTY, so turn it into a DUNDEFINED.

This adds a new get(Type)Vars method for every action type. The goal is
to 1-have shorter methods, which is always good; 2-try to make this code
a bit more testable.
I left as a todo moving all these methods to a separate class, the idea
being to make them non-static and thus easier to be tested.

I5ec4ab44c4e88aaf18c0d7b73355d27050beeda7 almost fixed this bug, but we
also have to make it possible to access builtin variables as arrays.
This will only make sense for a few variables (e.g. added_lines and
removed_lines), but I don't think we should validate it when checking
syntax.

Instead of having three keys, one for total actions, one for time and
one for conditions. This has several benefits: first, it avoids race
conditions which could happen having different keys. Second, it's much
more performant. Third, the code is also clearer to understand,
and more uniform with the one for global stats.

This is the proper solution to replace
Ia8e38ba25d1989fe71714d2b76891c4587921466, using a class member and an
additional method. Plus, change checkFilter not to accept a prefix, but a boolean indicating if the filter is global (as that's how it's used currently).
This change also fixes an issue which caused profiling data for local
filters to be mixed with profiling data for global filters with the same
ID.

This patch includes:
* Making it possible to access offsets of a DNONE (returning a DNONE)
* Initializing user-defined variables as DNONE inside short-circuited branches
* Make DNONE propagate with other operators
* Make DNONE count as false for logic operators
* Remove a now-outaded bit in doLevelAtom. In case of shortcircuit,
$result is now DNONE instead of DNULL, and thus it's possible to
access offsets of it. Performance++!
* Don't allow modifying or adding an element of a DNONE as if it were an
array (to avoid inconsistencies)
This re-applies Id85c673337fa90a3782fd22eb9690cd996967111 with several fixes.
NOTE: Haven't tested locally, although I'm pretty confident thanks to
