Bug #: 31098
Summary: Abysmal parser performance with certain kind of
recursive input
Product: MediaWiki
Version: 1.19-svn
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: Unprioritized
Component: Parser
AssignedTo: tstarl...@wikimedia.org
ReportedBy: niklas.laxst...@gmail.com
Classification: Unclassified
Recent commits surfaced abysmal parser performance bug with certain kind of
input. Basically it is a template, which uses {{int}} to fetch few messages,
which call the template again. This seems to avoid all depth and size related
checks that should prevent this kind of thing happening.
Will commit a minimal parser test that demonstrates the problem.
