This is consistent with the "anti-DoS" measures on other API modules.
Although this may not be a serious DoS vector, it makes sense to
restrict this module. Moreover, it's also consistent with
Special:AbuseFilter/tools (which is the corresponding web interface),
which requires the same user rights.

AbuseFilterViewEdit does privilege checks based on filter ID,
and displays what is hidden under given history ID, but doesn't
make sure those two IDs actually belong to one filter.
That means user can easily change filter ID to a public
filter and view old versions of nowadays private filters.

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.").

This bumps the level to WARN, and makes it very clear that people should
fix the affected filters. It also removes the calling method, which was
mostly meant for debugging purposes, and changes the type to 'op_type'
to avoid conflicting with type:mediawiki in logstash.

Always run the keyword/function handler, even if there are DUNDEFINED
arguments, so that the handler can perform further validation on the
input and report any error to the user. However, replace DUNDEFINED with
DNULL before running the handler, to avoid special-casing DUNDEFINED in
every handler. If any argument was a DUNDEFINED, we will return
DUNDEFINED anyway.
Also centralize the keyword handling logic to a new method, like it
happens for functions.

This allows sharing the code between cachingparser and the old parser
(for DRY-ness), and even when the old parser will be killed, having the
logic outside of the generic parse method seems saner.

This emits its own error because:
1- It's clearer to understand

As the code comment says, and as it was suggested in

Instead of checking if the filter is currently hidden, check the

only show the diff if none of the revision is hidden.
Also avoid showing a "diff" link if the user cannot see it.

In Ib7427e15f673a575738489476e604c387f449ddd, I thought that $parameters could've only been null if $action wasn't
enabled, but actually, they're null even if the action is just not set.
Which is true for all actions when creating a new filter, and all
non-set actions when editing an existing one.
Hence, revert the part that touched ViewEdit.
Also add a selenium test to ensure that warn parameters are visible.

The method, which simply duplicates an AFPData instance, is only used
when casting types, to return a different instance when the object
already has the desired type.
However, nothing is assuming that, so we can just return the original
instance and save some time.

This is a micro-optimization, but IMHO it's necessary. The AF parser
code is executed for every active filter, for every
edit/move/deletion/accountcreation. In PHP, foreach is usually faster
than array_map. Especially in the case of variadic functions potentially
taking hundreds of strings, foreach will consume less time.

Setting 'apiHookResult' results in a "successful" response; if we want
to report an error, we need to use ApiMessage. We already were doing
this for action=upload. Now our action=edit API responses will be
consistent with MediaWiki and other extensions, and will be able to
take advantage of errorformat=html.
Since this breaks compatibility anyway, also remove some redundant
backwards-compatibility values from the output.
To avoid user interface regressions in VisualEditor, the changes
I3b9c4fef (in VE) and I106dbd3c (in MediaWiki) should be merged first.

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.

There's not need to use the variableholder in this hacky (albeit common)
whay, since the row already holds the action.
Note, this doesn't guarantee that the next two lines won't fail - I'd

why this is failing.

IMHO these can be considered unit tests; they were already fast, but now
they're executed in an instant.
This requires several changes: 1 - delay retrieving messages in
AFPUserVisibleException, to avoid having to deal with i18n whenever we
want to test exceptions; 2 - Use some DI for Parser and Tokenizer.
Equivset-dependend tests are also moved to a new class, thus helping to
fix the AF part of T189560.

There are lots of calls to $user->isAllowed which could be simplified
using available accessors like canEdit(). So simplify those calls and

several text fields, while blocked users cannot actually edit filters.

There are lots of cases where we can inject a User object without
additional efforts. Now $wgUser is only used inside AFComputedVariable,
which is a little bit harder to handle because some instances of that
class are serialized in the DB, and thus we cannot easily change the
constructor until T213006 is resolved.
This partly copies what Ia474f02dfeee8c7d067ee7e555c08cbfef08f6a6 tried
to do, but adopting a different approach for various can*() methods:
they're now static methods in the AbuseFilter class, so future callers
don't need to instantiate an AbuseFilterView class. This also allows to
re-use those methods in an API module for editing filters (T213037).

While this is not as important as throwing for too few parameters, IMHO
it's still important to fail in this case. Mostly because if a function

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
reporting outofbounds errors.
