will be fixed. AFAICS, there's nothing wrong in there, but we'll see on
future phpunit executions.

Use a single function to check parameters amount, avoid duplication
between keywordIn and keywordContains, use if...elseif instead of
if-else when statements have a return inside, simplify some other logic,
add typehinting, and change method visibility according to use of such
methods.

Variables regarding title (full list in task description) are quite
deceiving, since they use "text" instead of "title". As proposed in the
task, this is the first patch to add aliases for those variables and
slightly deprecate the old ones. In the future we may be able to replace
every occurrence (either with a search function or directly on the
database), but even a coexistence would be enough to avoid
confusion. A wfDebug log is generated whenever a deprecated variable is
parsed. The "article_" prefix is also changed to "title_", in the same
way as above.
Also, added a hook which other extension may use to specify their
deprecated variables, which will be handled the same as core ones.

Add some tests and improve others to raise coverage percentage. This
should lead to almost 100% for the AbuseFilterParser class. Aside from
this, a couple of changes:
* Remove an unused function
* Let equals_to_any return a genuine result with empty strings
* Remove an if which will never be true in skipOverBraces, since the
function is called after checking the same conditions.

Arrays were introduced with the name "lists". While it **may** look

different from arrays. I ran a grep and I should've replaced

wouldn't be bad.

Introduce a new function which can be used to group multiple comparisons
in a single condition. In particular, equals_to_any(S, A, B) is the
equivalent of S === A || S === B. This is especially useful in checking
for multiple namespaces, as proposed in the Community health initiative.

I am pretty sure all of the behavior documented in these tests is a bad
idea. It is possible that we can fix it since some of those features
are probably unused, but for now those tests will serve as a
documentation of the current behavior.
Change-Id: Ia2a2f57a538d7aef2ac73fb2e47fe82dd5d5e09a
substr_count() is just as fast as looped strpos() when there are no
matches, and gets faster as the number of matches increases.
Note that this introduces a small change in behavior when the needle
is composed of repeated substrings, e.g. 'asdasdasd' or 'aa', and
haystack is such that the needle can be matched in overlapping
positions, e.g. 'asdasdasdasd' or 'aaaaa'. The old implementation
counted overlapping matches, the new one doesn't. I don't think this
behavior was intentional and I don't think this change will cause any
real problems.
Change-Id: Icc905ca34bf08d63e969787a5e3c119d498bf878
Previously, 'false & a == b' would actually execute the comparison and
count it against the condition limit, while 'false & (a == b)' wouldn't.
They behave the same now.
mShortCircuit was only checked for the most potentially expensive
operations (computing functions and getting variables), all the other
operations on bogus values generated by this would be executed and the
results ignored later.
This probably doesn't noticeably improve performance, but it corrects
how the condition limit is counted.

Change-Id: Id1d5f577b14b6ae6d987ded12689788eb7922474
With the new behavior, the number of conditions in incremented when:
* Evaluating a function
* Evaluating a comparison operator (== === != !== < > <= >= =)
* Evaluating a keyword (in like matches contains rlike irlike regex)
Previously, the number of conditions was incremented when:
* Evaluating a function
* Entering the comparison operator evaluation mode
This resulted in a number of surprising behaviors. In particular:
* '(((a == b)))' counted as 4 conditions, not 1
* 'contains_any(a, b, c)' counted as 5 conditions, not 1
* 'a == b == c' counted as 1 condition, not 2
* 'a in b + c in d + e in f' counted as 1 condition, not 3
* 'true' counted as 1 condition, not 0
It is still possible to easily cheat the count by rewriting comparisons
as arithmetic operations. I believe this is meant to advise users of
the complexity of their rules and not really enforce strict limits.

* Removed AbuseFilterParser::lastHandledToken and AFPParserState::lastInput,
because AbuseFilterParser::nextToken() no longer calls itself recursively.
* The regular expression that matches operators is no longer constructed
dynamically, but hard-coded into the class. To make sure it does not drift
apart from the more legible AbuseFilterParser::$mOps, add a unit test that
constructs the regex dynamically as before and compares it to
AbuseFilterParser::OPERATOR_RE.
* AbuseFilterParser::RADIX_RE ditto.

The abusefilter array test failed because length( ['a', 'b', 'c'] )
returned 12 instead of 6. That was du to it converted the array
to a string with new line seperated values first before measuring
the string length. Changed that behaviour to act like the php count()
function or the python len() function which seems far more useful to me.
The old behaviour can be established using length( string( array ) ).

I've made it more performant and fixed a few bugs by using regexes
instead of PHP loops, where possible, under the assumption that the
PCRE parser is more efficient than the same thing implemented in pure PHP.
Also, I'm now passing the same string around and calculating offsets, which
Tim tells me is far more performant than continually truncating the same string.
All tests still pass, with the exception of string.t, which I've modified
to remove the offending code, which never worked.
