I have just put the tarballs for the 10.30-RC1 test release in the usual place:
ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/Testing/pcre2-10.30-RC1.tar.gz ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/Testing/pcre2-10.30-RC1.tar.bz2 ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/Testing/pcre2-10.30-RC1.zip This is a major upgrade (hence the version jump). The full list of changes that includes bugfixes and tidies is, as always, in ChangeLog, and the new features are summarized in NEWS. The most important change is that the pcre2_match() function has been refactored into a new version that does not use recursive function calls (and therefore the system stack) for remembering backtracking positions. This makes --disable-stack-for-recursion a NOOP, and "stack overflow" errors should be no more. The new implementation allows backtracking into recursive group calls in patterns, making it more compatible with Perl, and also fixes some other previously hard-to-do issues. For patterns that have a lot of backtracking, the heap is now used, and there is explicit limit on the amount, settable by pcre2_set_heap_limit() or (*LIMIT_HEAP=xxx). The "recursion limit" is retained, but is renamed as "depth limit" (though the old names remain for compatibility). The documentation is updated (I hope I haven't missed anything). Please test the code and the documentation as much as possible. I would like to put out the actual release in about a month's time.
