Replace Free Software Foundation address in license notices

2017-11-09T04:21:21+00:00

The mailing address for the FSF has changed over the years.  Rather than
updating the address across all files, refer readers to gnu.org, as the
GNU GPL documentation now suggests for license notices.  The mailing
address is retained in the full license files (COPYING and LGPL-2.1).

The old address is still present in t/diff-lib/COPYING.  This is
intentional, as the file is used in tests and the contents are not
expected to change.

regex: fix a SIZE_MAX macro redefinition warning

2016-06-07T02:22:00+00:00

Since commit 56a1a3ab ("Silence GCC's \"cast of pointer to integer of a
different size\" warning", 26-10-2015), sparse has been issuing a macro
redefinition warning for the SIZE_MAX macro. However, gcc did not issue
any such warning.

After commit 56a1a3ab, in terms of the order of #includes and #defines,
the code looked something like:

  $ cat -n junk.c
       1	#include 
       2
       3	#define SIZE_MAX ((size_t) -1)
       4
       5	#include 
       6
       7	int main(int argc, char *argv[])
       8	{
       9		return 0;
      10	}
  $
  $ gcc junk.c
  $

However, if you compile that file with -Wsystem-headers, then it will
also issue a warning. Having set -Wsystem-headers in CFLAGS, using the
config.mak file, then (on cygwin):

  $ make compat/regex/regex.o
      CC compat/regex/regex.o
  In file included from /usr/lib/gcc/x86_64-pc-cygwin/4.9.3/include/stdint.h:9:0,
                   from compat/regex/regcomp.c:21,
                   from compat/regex/regex.c:77:
  /usr/include/stdint.h:362:0: warning: "SIZE_MAX" redefined
   #define SIZE_MAX (__SIZE_MAX__)
   ^
  In file included from compat/regex/regex.c:69:0:
  compat/regex/regex_internal.h:108:0: note: this is the location of the previous definition
   # define SIZE_MAX ((size_t) -1)
   ^
  $

The compilation of the compat/regex code is somewhat unusual in that the
regex.c file directly #includes the other c files (regcomp.c, regexec.c
and regex_internal.c). Commit 56a1a3ab added an #include of 
to the regcomp.c file, which results in the redefinition, since this is
included after the regex_internal.h header. This header file contains a
'fallback' definition for SIZE_MAX, in order to support systems which do
not have the  header (the HAVE_STDINT_H macro is not defined).

In order to suppress the warning, we move the #include of 
from regcomp.c to the start of the compilation unit, close to the top
of regex.c, prior to the #include of the regex_internal.h header.

compat/regex: use the regex engine from gawk for compat

2010-08-18T21:06:48+00:00

Change the regex engine in compat to use the gawk engine from the
gawk-devel module in gawk CVS. This engine supports the REG_STARTEND
flag, which was optionally available in Git since v1.7.2-rc0~77^2~1.

The source was grabbed from cvs.savannah.gnu.org:/sources/gawk, and
these are the upstream versions of the files being included:

    regcomp.c               1.4
    regex.h                 1.3
    regex.h                 1.3
    regex_internal.c        1.3
    regex_internal.h        1.3
    regexec.c               1.3

Change regerror() declaration from K&R style to ANSI C (C89)

2009-09-19T03:00:42+00:00

The MSVC headers typedef errcode as int, and thus confused the compiler in
the K&R style definition. ANSI style deconfuses it.

Use compatibility regex library for OSX/Darwin

2008-09-10T20:36:40+00:00

The standard libc regex library on OSX does not support alternation
in POSIX Basic Regular Expression mode.  This breaks the diff.funcname
functionality on OSX.

To fix this, we use the GNU regex library which is already present in
the compat/ diretory for the MinGW port.  However, simply adding compat/
to the COMPAT_CFLAGS variable causes a conflict between the system
fnmatch.h and the one present in compat/.  To remedy this, move the
regex and fnmatch functionality to their own subdirectories in compat/
so they can be included seperately.
