Hi All,
The source code to a MediaWiki Parser fuzz-tester is now available online at: http://files.nickj.org/MediaWiki/wiki-mangleme.phps
Some of the problems it has found are listed at: http://nickj.org/MediaWiki
With MediaWiki 1.6.5, the breakdown of stuff I'm currently seeing that messes up the flow of tags (as opposed to just failing HTML validation) is roughly: * 50% Table-Of-Contents insertion ( See Parser14 test at above URL) * 30% double links ( See Parser22 test at above URL) * 20% is <nowiki> or <pre> insertion + multi-line URLs ( See Parser20 and Parser23 tests respectively ).
All the best, Nick.
