# Line 2  ChangeLog for PCRE Line 2  ChangeLog for PCRE
2  ------------------  ------------------
3    
4    
5    Version 3.4 22-Aug-00
6    ---------------------
7    
8    1. Fixed typo in pcre.h: unsigned const char * changed to const unsigned char *.
9    
10    2. Diagnose condition (?(0) as an error instead of crashing on matching.
11    
12    
13    Version 3.3 01-Aug-00
14    ---------------------
15    
16    1. If an octal character was given, but the value was greater than \377, it
17    was not getting masked to the least significant bits, as documented. This could
18    lead to crashes in some systems.
19    
20    2. Perl 5.6 (if not earlier versions) accepts classes like [a-\d] and treats
21    the hyphen as a literal. PCRE used to give an error; it now behaves like Perl.
22    
23    3. Added the functions pcre_free_substring() and pcre_free_substring_list().
24    These just pass their arguments on to (pcre_free)(), but they are provided
25    because some uses of PCRE bind it to non-C systems that can call its functions,
26    but cannot call free() or pcre_free() directly.
27    
28    4. Add "make test" as a synonym for "make check". Corrected some comments in
29    the Makefile.
30    
31    5. Add $(DESTDIR)/ in front of all the paths in the "install" target in the
32    Makefile.
33    
34    6. Changed the name of pgrep to pcregrep, because Solaris has introduced a
35    command called pgrep for grepping around the active processes.
36    
37    7. Added the beginnings of support for UTF-8 character strings.
38    
39    8. Arranged for the Makefile to pass over the settings of CC, CFLAGS, and
40    RANLIB to ./ltconfig so that they are used by libtool. I think these are all
41    the relevant ones. (AR is not passed because ./ltconfig does its own figuring
42    out for the ar command.)
43    
44    
45    Version 3.2 12-May-00
46    ---------------------
47    
48    This is purely a bug fixing release.
49    
50    1. If the pattern /((Z)+|A)*/ was matched agained ZABCDEFG it matched Z instead
51    of ZA. This was just one example of several cases that could provoke this bug,
52    which was introduced by change 9 of version 2.00. The code for breaking
53    infinite loops after an iteration that matches an empty string was't working
54    correctly.
55    
56    2. The pcretest program was not imitating Perl correctly for the pattern /a*/g
57    when matched against abbab (for example). After matching an empty string, it
58    wasn't forcing anchoring when setting PCRE_NOTEMPTY for the next attempt; this
59    caused it to match further down the string than it should.
60    
61    3. The code contained an inclusion of sys/types.h. It isn't clear why this
62    was there because it doesn't seem to be needed, and it causes trouble on some
63    systems, as it is not a Standard C header. It has been removed.
64    
65    4. Made 4 silly changes to the source to avoid stupid compiler warnings that
66    were reported on the Macintosh. The changes were from
67    
68      while ((c = *(++ptr)) != 0 && c != '\n');
69    to
70      while ((c = *(++ptr)) != 0 && c != '\n') ;
71    
72    Totally extraordinary, but if that's what it takes...
73    
74    5. PCRE is being used in one environment where neither memmove() nor bcopy() is
75    available. Added HAVE_BCOPY and an autoconf test for it; if neither
76    HAVE_MEMMOVE nor HAVE_BCOPY is set, use a built-in emulation function which
77    assumes the way PCRE uses memmove() (always moving upwards).
78    
79    6. PCRE is being used in one environment where strchr() is not available. There
80    was only one use in pcre.c, and writing it out to avoid strchr() probably gives
81    faster code anyway.
82
