1  ChangeLog for PCRE  ChangeLog for PCRE
2  ------------------  ------------------
3    
4    Version 3.8 18-Dec-01
5    ---------------------
6    
7    1. The experimental UTF-8 code was completely screwed up. It was packing the
8    bytes in the wrong order. How dumb can you get?
9    
10    
11    Version 3.7 29-Oct-01
12    ---------------------
13    
14    1. In updating pcretest to check change 1 of version 3.6, I screwed up.
15    This caused pcretest, when used on the test data, to segfault. Unfortunately,
16    this didn't happen under Solaris 8, where I normally test things.
17    
18    2. The Makefile had to be changed to make it work on BSD systems, where 'make'
19    doesn't seem to recognize that ./xxx and xxx are the same file. (This entry
20    isn't in ChangeLog distributed with 3.7 because I forgot when I hastily made
21    this fix an hour or so after the initial 3.7 release.)
22    
23    
24    Version 3.6 23-Oct-01
25    ---------------------
26    
27    1. Crashed with /(sens|respons)e and \1ibility/ and "sense and sensibility" if
28    offsets passed as NULL with zero offset count.
29    
30    2. The config.guess and config.sub files had not been updated when I moved to
31    the latest autoconf.
32    
33    
34    Version 3.5 15-Aug-01
35    ---------------------
36    
37    1. Added some missing #if !defined NOPOSIX conditionals in pcretest.c that
38    had been forgotten.
39    
40    2. By using declared but undefined structures, we can avoid using "void"
41    definitions in pcre.h while keeping the internal definitions of the structures
42    private.
43    
44    3. The distribution is now built using autoconf 2.50 and libtool 1.4. From a
45    user point of view, this means that both static and shared libraries are built
46    by default, but this can be individually controlled. More of the work of
47    handling this static/shared cases is now inside libtool instead of PCRE's make
48    file.
49    
50    4. The pcretest utility is now installed along with pcregrep because it is
51    useful for users (to test regexs) and by doing this, it automatically gets
52    relinked by libtool. The documentation has been turned into a man page, so
53    there are now .1, .txt, and .html versions in /doc.
54    
55    5. Upgrades to pcregrep:
56       (i)   Added long-form option names like gnu grep.
57       (ii)  Added --help to list all options with an explanatory phrase.
58       (iii) Added -r, --recursive to recurse into sub-directories.
59       (iv)  Added -f, --file to read patterns from a file.
60    
61    6. pcre_exec() was referring to its "code" argument before testing that
62    argument for NULL (and giving an error if it was NULL).
63    
64    7. Upgraded Makefile.in to allow for compiling in a different directory from
65    the source directory.
66    
67    8. Tiny buglet in pcretest: when pcre_fullinfo() was called to retrieve the
68    options bits, the pointer it was passed was to an int instead of to an unsigned
69    long int. This mattered only on 64-bit systems.
70    
71    9. Fixed typo (3.4/1) in pcre.h again. Sigh. I had changed pcre.h (which is
72    generated) instead of pcre.in, which it its source. Also made the same change
73    in several of the .c files.
74    
75    10. A new release of gcc defines printf() as a macro, which broke pcretest
76    because it had an ifdef in the middle of a string argument for printf(). Fixed
77    by using separate calls to printf().
78    
79    11. Added --enable-newline-is-cr and --enable-newline-is-lf to the configure
80    script, to force use of CR or LF instead of \n in the source. On non-Unix
81    systems, the value can be set in config.h.
82    
83    12. The limit of 200 on non-capturing parentheses is a _nesting_ limit, not an
84    absolute limit. Changed the text of the error message to make this clear, and
85    likewise updated the man page.
86    
87    13. The limit of 99 on the number of capturing subpatterns has been removed.
88    The new limit is 65535, which I hope will not be a "real" limit.
89    
90    
91    Version 3.4 22-Aug-00
92    ---------------------
93    
94    1. Fixed typo in pcre.h: unsigned const char * changed to const unsigned char *.
95    
96    2. Diagnose condition (?(0) as an error instead of crashing on matching.
97    
98    
99  Version 3.3 01-Aug-00  Version 3.3 01-Aug-00
100  ---------------------  ---------------------
