Your patches look good. Attached are the v44 pathes, with minor fixes
to docs (mention that reluctant quantifiers are supported, exclusion
and empty PATTERN are not supported). Also makes clear the range of n
and m in {n, m} and other regular expression.
---- Major differences from v43 patches ----
- Implement reluctant quantifiers
- Disallow using PREV()/NEXT() in other than the DEFINE caluse
- Reject qualied column references in the DEFINE clause
- Fix explain test failures on 32bit platforms
- Fix and cleanup the NFA engine
- Fix docs that reluctant quantifiers are supported, exclusion and
empty PATTERN are not supported.
- Some code refactorings
Best regards,
