# Line 2  ChangeLog for PCRE Line 2  ChangeLog for PCRE
2  ------------------  ------------------
5    Version 2.08 31-Aug-99
6    ----------------------
8    1. When startoffset was not zero and the pattern began with ".*", PCRE was not
9    trying to match at the startoffset position, but instead was moving forward to
10    the next newline as if a previous match had failed.
12    2. pcretest was not making use of PCRE_NOTEMPTY when repeating for /g and /G,
13    and could get into a loop if a null string was matched other than at the start
14    of the subject.
16    3. Added definitions of PCRE_MAJOR and PCRE_MINOR to pcre.h so the version can
17    be distinguished at compile time, and for completeness also added PCRE_DATE.
19    5. Added Paul Sokolovsky's minor changes to make it easy to compile a Win32 DLL
20    in GnuWin32 environments.
23    Version 2.07 29-Jul-99
24    ----------------------
26    1. The documentation is now supplied in plain text form and HTML as well as in
27    the form of man page sources.
29    2. C++ compilers don't like assigning (void *) values to other pointer types.
30    In particular this affects malloc(). Although there is no problem in Standard
31    C, I've put in casts to keep C++ compilers happy.
33    3. Typo on pcretest.c; a cast of (unsigned char *) in the POSIX regexec() call
34    should be (const char *).
36    4. If NOPOSIX is defined, pcretest.c compiles without POSIX support. This may
37    be useful for non-Unix systems who don't want to bother with the POSIX stuff.
38    However, I haven't made this a standard facility. The documentation doesn't
39    mention it, and the Makefile doesn't support it.
41    5. The Makefile now contains an "install" target, with editable destinations at
42    the top of the file. The pcretest program is not installed.
44    6. pgrep -V now gives the PCRE version number and date.
46    7. Fixed bug: a zero repetition after a literal string (e.g. /abcde{0}/) was
47    causing the entire string to be ignored, instead of just the last character.
49    8. If a pattern like /"([^\\"]+|\\.)*"/ is applied in the normal way to a
50    non-matching string, it can take a very, very long time, even for strings of
51    quite modest length, because of the nested recursion. PCRE now does better in
52    some of these cases. It does this by remembering the last required literal
53    character in the pattern, and pre-searching the subject to ensure it is present
54    before running the real match. In other words, it applies a heuristic to detect
55    some types of certain failure quickly, and in the above example, if presented
56    with a string that has no trailing " it gives "no match" very quickly.
58    9. A new runtime option PCRE_NOTEMPTY causes null string matches to be ignored;
59    other alternatives are tried instead.
