Ramsay Jones	bd8f005583	regex: fix a SIZE_MAX macro redefinition warning 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 <stddef.h> 2 3 #define SIZE_MAX ((size_t) -1) 4 5 #include <stdint.h> 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 <stdint.h> 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 <stdint.h> header (the HAVE_STDINT_H macro is not defined). In order to suppress the warning, we move the #include of <stdint.h> 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.

Johannes Schindelin	56a1a3ab44	Silence GCC's "cast of pointer to integer of a different size" warning When calculating hashes from pointers, it actually makes sense to cut off the most significant bits. In that case, said warning does not make a whole lot of sense. So let's just work around it by casting the pointer first to intptr_t and then casting up/down to the final integral type.

Junio C Hamano	c01499ef69	C: have space around && and \|\| operators Correct all hits from git grep -e '\(&&\\|\|\|\)[^ ]' -e '[^ ]\(&&\\|\|\|\)' -- '*.c' i.e. && or \|\| operators that are followed by anything but a SP, or that follow something other than a SP or a HT, so that these operators have a SP around it when necessary. We usually refrain from making this kind of a tree-wide change in order to avoid unnecessary conflicts with other "real work" patches, but in this case, the end result does not have a potentially cumbersome tree-wide impact, while this is a tree-wide cleanup. Fixes to compat/regex/regcomp.c and xdiff/xemit.c are to replace a HT immediately after && with a SP. This is based on Felipe's patch to bultin/symbolic-ref.c; I did all the finding out what other files in the whole tree need to be fixed and did the fix and also the log message while reviewing that single liner, so any screw-ups in this version are mine.

Junio C Hamano	178b33157a	compat/regex: get rid of old-style definition These files mostly used ANSI style function definitions, but with small number of old-style ones. Convert them to consistently use ANSI style. Signed-off-by: Junio C Hamano <gitster@pobox.com>	15 years ago
Frank Li	de831726de	Change regerror() declaration from K&R style to ANSI C (C89) The MSVC headers typedef errcode as int, and thus confused the compiler in the K&R style definition. ANSI style deconfuses it. This patch was originally applied as v1.6.5-rc2~23 but needs to be re-applied since compat/regex was overwritten by Ævar Arnfjörð Bjarmason with the gawk regex engine.

Ævar Arnfjörð Bjarmason	d18f76dccf	compat/regex: use the regex engine from gawk for compat 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 Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Acked-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	15 years ago
