Andrew Garrett db3c0bbe05 Fix regex error handling by returning immediately if error reporting is disabled. 2009-06-17 11:38:31 +00:00
Andrew Garrett 6678b42d8e Remove special-case list handling for contains_any, len, like/in -- breaks backwards-compatibility with old filters. 2009-06-16 14:28:00 +00:00
Andrew Garrett 48bfcc35ee Various code quality fixes for AbuseFilter suggested by Tim Starling in a private email, including bugfixes, memory safeguards, performance improvements, removal of redundant code, consolidation of similar functionaality. 2009-05-26 13:08:15 +00:00
Tim Starling da372fdec0 Reverted r49855, r49656, r49401, r49399, r49397. The language converter cannot be used outside the parser at present without generating a large number of bugs, due to global lifetime state variables, inappropriate $wgParser references, etc. Some refactoring needs to be done before it can be used in this way. 2009-05-26 07:46:29 +00:00

Andrew Garrett 55b417f517 Add rcount function, same as count except it takes a regex as the needle 2009-03-07 01:26:42 +00:00
Andrew Garrett e60dee6cac Add an interface for extensions to add variables into the variable list (only for ones generated for filtering, for now). Includes an implementation in the TorBlock extension 2009-03-05 02:43:05 +00:00
Andrew Garrett 92698e95ba Improve AbuseFilter performance by implementing lazy initialisation of computed variables.
This has been done by replacing simple associative arrays with an AbuseFilterVariableHolder, which recognises helper classes called AFComputedVariables.
Computation may occur during the abuse filter analysis, or later when testing and reviewing filters.

Andrew Garrett 35e61feeb6 Abuse Filter Parser updates
* Deprecate parseTokens in favour of a parse-as-you-go approach, faster and uses less memory.
* Display variables in lower_case so they aren't SHOUTING_AT_PEOPLE.
* Tell people if they try to use variables that don't exist, rather than silently returning NULL.

Andrew Garrett 0880f444b1 Abuse Filter Parser updates:
* Use strcspn to scan ahead for long regions of uninteresting text in string handling (performance).
* Remove cruft specific to my system in phpTest.php.
* Remove a test that was in incorrect syntax, and useless without adding variable support.

Andrew Garrett bfe57be65d Rewrite of Abuse Filter parser tokeniser.
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.
