Summary: Faster logic for Abuse Filter parser
Product: MediaWiki extensions
Version: any
Platform: All
OS/Version: All
Status: NEW
Severity: enhancement
Priority: Normal
Component: AbuseFilter
AssignedTo: [email protected]
ReportedBy: [email protected]

The attached patch improves the execution speed of AbuseFilterParser::nextToken
through a series of small changes.
The most significant impact comes from modifying the application of regex to
focus on the immediate offset and not look downstream unnecessarily. It also
stops radixRegex from giving empty string matches.
This patch preserves all current behavior and is transparent to the user.
Benchmarking done with function evaluation and variable lookup hacked off, saw
a ~20% improvement in the parsing speed for rules after applying this patch.
