1  ChangeLog for PCRE  ChangeLog for PCRE
2  ------------------  ------------------
4    Version 3.6 23-Oct-01
5    ---------------------
7    1. Crashed with /(sens|respons)e and \1ibility/ and "sense and sensibility" if
8    offsets passed as NULL with zero offset count.
10    2. The config.guess and config.sub files had not been updated when I moved to
11    the latest autoconf.
14    Version 3.5 15-Aug-01
15    ---------------------
17    1. Added some missing #if !defined NOPOSIX conditionals in pcretest.c that
18    had been forgotten.
20    2. By using declared but undefined structures, we can avoid using "void"
21    definitions in pcre.h while keeping the internal definitions of the structures
22    private.
24    3. The distribution is now built using autoconf 2.50 and libtool 1.4. From a
25    user point of view, this means that both static and shared libraries are built
26    by default, but this can be individually controlled. More of the work of
27    handling this static/shared cases is now inside libtool instead of PCRE's make
28    file.
30    4. The pcretest utility is now installed along with pcregrep because it is
31    useful for users (to test regexs) and by doing this, it automatically gets
32    relinked by libtool. The documentation has been turned into a man page, so
33    there are now .1, .txt, and .html versions in /doc.
35    5. Upgrades to pcregrep:
36       (i)   Added long-form option names like gnu grep.
37       (ii)  Added --help to list all options with an explanatory phrase.
38       (iii) Added -r, --recursive to recurse into sub-directories.
39       (iv)  Added -f, --file to read patterns from a file.
41    6. pcre_exec() was referring to its "code" argument before testing that
42    argument for NULL (and giving an error if it was NULL).
44    7. Upgraded Makefile.in to allow for compiling in a different directory from
45    the source directory.
47    8. Tiny buglet in pcretest: when pcre_fullinfo() was called to retrieve the
48    options bits, the pointer it was passed was to an int instead of to an unsigned
49    long int. This mattered only on 64-bit systems.
51    9. Fixed typo (3.4/1) in pcre.h again. Sigh. I had changed pcre.h (which is
52    generated) instead of pcre.in, which it its source. Also made the same change
53    in several of the .c files.
55    10. A new release of gcc defines printf() as a macro, which broke pcretest
56    because it had an ifdef in the middle of a string argument for printf(). Fixed
57    by using separate calls to printf().
59    11. Added --enable-newline-is-cr and --enable-newline-is-lf to the configure
60    script, to force use of CR or LF instead of \n in the source. On non-Unix
61    systems, the value can be set in config.h.
63    12. The limit of 200 on non-capturing parentheses is a _nesting_ limit, not an
64    absolute limit. Changed the text of the error message to make this clear, and
65    likewise updated the man page.
67    13. The limit of 99 on the number of capturing subpatterns has been removed.
68    The new limit is 65535, which I hope will not be a "real" limit.
71    Version 3.4 22-Aug-00
72    ---------------------
74    1. Fixed typo in pcre.h: unsigned const char * changed to const unsigned char *.
76    2. Diagnose condition (?(0) as an error instead of crashing on matching.
79    Version 3.3 01-Aug-00
80    ---------------------
82    1. If an octal character was given, but the value was greater than \377, it
83    was not getting masked to the least significant bits, as documented. This could
84    lead to crashes in some systems.
86    2. Perl 5.6 (if not earlier versions) accepts classes like [a-\d] and treats
87    the hyphen as a literal. PCRE used to give an error; it now behaves like Perl.
89    3. Added the functions pcre_free_substring() and pcre_free_substring_list().
90    These just pass their arguments on to (pcre_free)(), but they are provided
91    because some uses of PCRE bind it to non-C systems that can call its functions,
92    but cannot call free() or pcre_free() directly.
94    4. Add "make test" as a synonym for "make check". Corrected some comments in
95    the Makefile.
97    5. Add $(DESTDIR)/ in front of all the paths in the "install" target in the
98    Makefile.
100    6. Changed the name of pgrep to pcregrep, because Solaris has introduced a
101    command called pgrep for grepping around the active processes.
103    7. Added the beginnings of support for UTF-8 character strings.
105    8. Arranged for the Makefile to pass over the settings of CC, CFLAGS, and
106    RANLIB to ./ltconfig so that they are used by libtool. I think these are all
107    the relevant ones. (AR is not passed because ./ltconfig does its own figuring
108    out for the ar command.)
