This makes VariableHolder a true value object, and introduces a
stateless service, VariableManager, to operate on it.
Note, in theory, this new service is still cyclically coupled with
LazyVariableComputed. However, it's now two stateless service being
coupled, not two smart/god value objects, so we've still earned
something. For now, the dependency is hidden by using a callback. Some
alternatives for that are mentioned in a code comment.

This is just a temporary location for these two methods. Since they're

dependency graph is unnecessarily complicated. Thus, since these methods

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 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.

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.

- Add a helper method to output an unrecoverable error, comprising a

- 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.

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 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.

more likely to be spotted.

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.

The editing view is currently full of tech debt, brittle and surprising
code and whatnot. It's basically a miracle if it works without problem,
and it'd be an even bigger miracle if you could change something there
without breaking anything.
For these reasons, and because that class must be refactored as part of
the upcoming overhaul, this patch adds a bunch of selenium tests to test
the main functionality of that page.
In particular, these tests cover all possible cases (each corresponding
to a data source) for which buildFilterEditor can be called, which FTR are:
1 - View the result of importing a filter
2 - Create a new filter
3 - Load the current version of an existing filter
4 - Load an old version of an existing filter
5 - Show the user input again if saving fails after one of the steps
above
Having automated tests to cover these cases means that we don't have to
manually test all the scenarios manually each time the class is touched.

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

This was used to dynamically generate *_restriction_* variables.
However, it had two big problems:
- We only have i18n for 'create', 'move', 'edit', and 'upload' (the
default value of the global); other restrictions would show missing
messages in various pages.
- We had to access the global state in various points.
This change also makes some code in AbuseFilterVariableHolder simpler,
and also allows us to make AbuseFilterTest a unit test.

At the moment there's no validation for import data, so it's totally

This is another step needed to reduce the size of the gigantic
AbuseFilter and AbuseFilterHooks classes. It also makes many methods
non-static, for more testability.
Note, this layout is still not final. We should somehow merge the

I already have plans.

RunVariableGenerator is for generating variables based on the current
action;
RowVariableGenerator is for RC entries;
VariableGenerator is the generic one.
This patch only moves the methods to the new classes, to keep the diff
easier to read, and facilitate conflict resolution. These classes will
then be revamped in I366d598b69ad866496b7cb0059e0835c02e54041.
Note that these classes are now namespaced.
One method, AbuseFilter::getEditVars, was renamed to
AbuseFilterVariableGenerator::generateEditVars, because it would
otherwise conflict with an incompatible method in RunVariableGenerator.

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

instead. Bonus: optimize a query to sort by afh_id instead of afh_timestamp to avoid filesort.

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.

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.").

arguments, so that the handler can perform further validation on the
input and report any error to the user. However, replace DUNDEFINED with

DUNDEFINED anyway.
Also centralize the keyword handling logic to a new method, like it

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

this for action=upload. Now our action=edit API responses will be

take advantage of errorformat=html.

While this is not as important as throwing for too few parameters, IMHO

In general, it's not safe to change configuration in the middle of a

This allows a little bit more of abstraction: we can store other data in the
tree, without having to store it in a specific node (e.g. the variables map,
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
guarantee. Last but not least, we can now measure runtime metrics for
evalTree, which doesn't recurse.
Bonus: fix a check in the old parser, which used the wrong variable when

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
catching the assert exception; simplify some assignments using wfSetVar.

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)`.

Currently we strongly abuse (pardon the pun) the AbuseFilter class: its
purpose should be to hold static functions intended as generic utility
functions (e.g. to format messages, determine whether a filter is global
etc.), but we actually use it for all methods related to running filters.
This patch creates a new class, AbuseFilterRunner, containing all such
methods, which have been made non-static. This leads to several
improvements (also for related methods and the parser), and opens the
way to further improve the code.
Aside from making the code prettier, less global and easier to test,
this patch could also produce a performance improvement, although I
don't have tools to measure that.
Also note that many public methods have been removed, and almost any of
them has been made protected; a couple of them (the ones used from outside)
are left for back-compat, and will be removed in the future.

This property is meant to be private, since it has all kinds of
getters/setters, aside from one which is introduced in this patch.

The current form is awkward. They're all like
[ actionname => [ 'action' => actionname, 'parameters' => params ] ]
This is greatly confusing since adds a nesting level, and just
duplicates the actionname information (also, we actually never retrieve
it from the internal array). Instead, change all of them to be
[ actionname => params ]
which is a lot shorter and clearer (and easier to handle).
A similar case is handled in I8134ecc41fbecdbed99faf406e9e3ca91b6123b9
(see PS 8..10).

As explained on phabricator, they don't work with shortcircuit, so they
already fail for all filters using them. Plus IMHO it's an unnecessary
deviation from PHP's behaviour, given that this syntax doesn't do what
users may expect.

Using the new PageEditStash class allows to simplify a bit the
integration tests for edit stashing. As I wrote in a ToDo, it may be
enough to manually run the hook, but that's left to do as a follow-up.

Instead of relying on static methods and members in the AbuseFilter
class, move everything related to conditions inside the Parser, as the
amount of used conditions is something pertaining a single
AbuseFilter(Caching)Parser instance.
This change requires changing some signatures and adding parameters,
but will make introducing the new AbuseFilterRunner class easier (and
that will clean signatures, too).
