* More work on bug #672491 and patch #712900.Gustavo Niemeyer2003-04-201-0/+4
| | | | | | | | | | | | | | | | I've applied a modified version of Greg Chapman's patch. I've included the fixes without introducing the reorganization mentioned, for the sake of stability. Also, the second fix mentioned in the patch don't fix the mentioned problem anymore, because of the change introduced by patch #720991 (by Greg as well). The new fix wasn't complicated though, and is included as well. As a note. It seems that there are other places that require the "protection" of LASTMARK_SAVE()/LASTMARK_RESTORE(), and are just waiting for someone to find how to break them. Particularly, I belive that every recursion of SRE_MATCH() should be protected by these macros. I won't do that right now since I'm not completely sure about this, and we don't have much time for testing until the next release.
* Fix from SF patch #633359 by Greg Chapman for SF bug #610299:Guido van Rossum2003-02-241-0/+1
| | | | | | | | | The problem is in sre_compile.py: the call to _compile_charset near the end of _compile_info forgets to pass in the flags, so that the info charset is not compiled with re.U. (The info charset is used when searching to find the first character at which a match could start; it is not generated for patterns beginning with a repeat like '\w{1}'.)

* Fixed bug #470582, using a modified version of patch #527371,Gustavo Niemeyer2002-11-061-0/+2
| | | | | | | | | | | | | | | | | | | from Greg Chapman. * Modules/_sre.c (lastmark_restore): New function, implementing algorithm to restore a state to a given lastmark. In addition to the similar algorithm used in a few places of SRE_MATCH, restore lastindex when restoring lastmark. (SRE_MATCH): Replace lastmark inline restoring by lastmark_restore(), function. Also include it where missing. In SRE_OP_MARK, set lastindex only if i > lastmark. * Lib/test/re_tests.py * Lib/test/test_sre.py Included regression tests for the fixed bugs. * Misc/NEWS Mention fixes.
