1  ChangeLog for PCRE  ChangeLog for PCRE
2  ------------------  ------------------
3    
4  Version 7.5 31-Dec-07  Version 7.7 05-Mar-08
5    ---------------------
6    
7    1.  Applied Craig's patch to sort out a long long problem: "If we can't convert
8        a string to a long long, pretend we don't even have a long long." This is
9        done by checking for the strtoq, strtoll, and _strtoi64 functions.
10    
11    2.  Applied Craig's patch to pcrecpp.cc to restore ABI compatibility with
12        pre-7.6 versions, which defined a global no_arg variable instead of putting
13        it in the RE class.
14    
15    3.  Remove a line of dead code, identified by coverity and reported by Nuno
16        Lopes.
17    
18    4.  Fixed two related pcregrep bugs involving -r with --include or --exclude:
19    
20        (1) The include/exclude patterns were being applied to the whole pathnames
21            of files, instead of just to the final components.
22    
23        (2) If there was more than one level of directory, the subdirectories were
24            skipped unless they satisfied the include/exclude conditions. This is
25            inconsistent with GNU grep (and could even be seen as contrary to the
26            pcregrep specification - which I improved to make it absolutely clear).
27            The action now is always to scan all levels of directory, and just
28            apply the include/exclude patterns to regular files.
29    
30    5.  Added the --include_dir and --exclude_dir patterns to pcregrep, and used
31        --exclude_dir in the tests to avoid scanning .svn directories.
32    
33    6.  Applied Craig's patch to the QuoteMeta function so that it escapes the
34        NUL character as backslash + 0 rather than backslash + NUL, because PCRE
35        doesn't support NULs in patterns.
36    
37    
38    Version 7.6 28-Jan-08
39    ---------------------
40    
41    1.  A character class containing a very large number of characters with
42        codepoints greater than 255 (in UTF-8 mode, of course) caused a buffer
43        overflow.
44    
45    2.  Patch to cut out the "long long" test in pcrecpp_unittest when
46        HAVE_LONG_LONG is not defined.
47    
48    3.  Applied Christian Ehrlicher's patch to update the CMake build files to
49        bring them up to date and include new features. This patch includes:
50    
51        - Fixed PH's badly added libz and libbz2 support.
52        - Fixed a problem with static linking.
53        - Added pcredemo. [But later removed - see 7 below.]
54        - Fixed dftables problem and added an option.
55        - Added a number of HAVE_XXX tests, including HAVE_WINDOWS_H and
56            HAVE_LONG_LONG.
57        - Added readline support for pcretest.
58        - Added an listing of the option settings after cmake has run.
59    
60    4.  A user submitted a patch to Makefile that makes it easy to create
61        "pcre.dll" under mingw when using Configure/Make. I added stuff to
62        Makefile.am that cause it to include this special target, without
63        affecting anything else. Note that the same mingw target plus all
64        the other distribution libraries and programs are now supported
65        when configuring with CMake (see 6 below) instead of with
66        Configure/Make.
67    
68    5.  Applied Craig's patch that moves no_arg into the RE class in the C++ code.
69        This is an attempt to solve the reported problem "pcrecpp::no_arg is not
70        exported in the Windows port". It has not yet been confirmed that the patch
71        solves the problem, but it does no harm.
72    
73    6.  Applied Sheri's patch to CMakeLists.txt to add NON_STANDARD_LIB_PREFIX and
74        NON_STANDARD_LIB_SUFFIX for dll names built with mingw when configured
75        with CMake, and also correct the comment about stack recursion.
76    
77    7.  Remove the automatic building of pcredemo from the ./configure system and
78        from CMakeLists.txt. The whole idea of pcredemo.c is that it is an example
79        of a program that users should build themselves after PCRE is installed, so
80        building it automatically is not really right. What is more, it gave
81        trouble in some build environments.
82    
83    8.  Further tidies to CMakeLists.txt from Sheri and Christian.
