News about PCRE2 releases
|
||||
-------------------------
|
||||
|
||||
Version 10.30-RC1 18-July-2017
|
||||
------------------------------
|
||||
|
||||
The full list of changes that includes bugfixes and tidies is, as always, in
|
||||
ChangeLog. These are the most important new features:
|
||||
|
||||
1. The main interpreter, pcre2_match(), 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. 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).
|
||||
|
||||
There is also a change in the way callouts from pcre2_match() are handled. The
|
||||
offset_vector field in the callout block is no longer a pointer to the
|
||||
actual ovector that was passed to the matching function in the match data
|
||||
block. Instead it points to an internal ovector of a size large enough to hold
|
||||
all possible captured substrings in the pattern.
|
||||
|
||||
2. The new option PCRE2_ENDANCHORED insists that a pattern match must end at
|
||||
the end of the subject.
|
||||
|
||||
3. The new option PCRE2_EXTENDED_MORE implements Perl's /xx feature, and
|
||||
pcre2test is upgraded to support it. Setting within the pattern by (?xx) is
|
||||
also supported.
|
||||
|
||||
4. (?n) can be used to set PCRE2_NO_AUTO_CAPTURE, because Perl now has this.
|
||||
|
||||
5. Additional compile options in the compile context are now available, and the
|
||||
first two are: PCRE2_EXTRA_ALLOW_SURROGATE_ESCAPES and
|
||||
PCRE2_EXTRA_BAD_ESCAPE_IS LITERAL.
|
||||
|
||||
6. The newline type PCRE2_NEWLINE_NUL is now available.
|
||||
|
||||
7. The match limit value now also applies to pcre2_dfa_match() as there are
|
||||
patterns that can use up a lot of resources without necessarily recursing very
|
||||
deeply.
|
||||
|
||||
8. The option REG_PEND (a GNU extension) is now available for the POSIX
|
||||
wrapper. Also there is a new option PCRE2_LITERAL which is used to support
|
||||
REG_NOSPEC.
|
||||
|
||||
9. PCRE2_EXTRA_MATCH_LINE and PCRE2_EXTRA_MATCH_WORD are implemented for the
|
||||
benefit of pcre2grep, and pcre2grep's -F, -w, and -x options are re-implemented
|
||||
using PCRE2_LITERAL, PCRE2_EXTRA_MATCH_WORD, and PCRE2_EXTRA_MATCH_LINE. This
|
||||
is tidier and also fixes some bugs.
|
||||
|
||||
10. The Unicode tables are upgraded from Unicode 8.0.0 to Unicode 10.0.0.
|
||||
|
||||
11. There are some experimental functions for converting foreign patterns
|
||||
(globs and POSIX patterns) into PCRE2 patterns.

||||
