Summary

0002907: Regex option 'A' ignored

Description

When a regex expression uses option 'A', the match functions must use the offest specified.

I have found this in mediawiki 1.12 code in this expression:

$elementsRegex = "~($xmlishRegex)(?:\s|\/>|>)|(!--)~iA";

subsequently used in a call to preg_match with offset specified.

Steps To Reproduce

Additional Information

I think the semantics of option 'A' is to anchor the search to the offset specified relative to the beginning of the text, while option '^' means to anchor to the beginning of the text.

I changed the test in RegexpNode.AnchorBegin.match:

// if (offset == 0)
if (offset == state._first)

This solves the problem at least for mediawiki.
