2011-05-27real_path: do not assume '/' is the path seperatorLibravatar Theo Niessink1-0/+4
real_path currently assumes it's input had '/' as path seperator. This assumption does not hold true for the code-path from prefix_path (on Windows), where real_path can be called before normalize_path_copy. Fix real_path so it doesn't make this assumption. Create a helper function to reverse-search for the last path-seperator in a string.

2011-04-08magic pathspec: futureproof shorthand formLibravatar Junio C Hamano1-0/+2
The earlier design was to take whatever non-alnum that the short format parser happens to support, leaving the rest as part of the pattern, so a version of git that knows '*' magic and a version that does not would have behaved differently when given ":*Makefile". The former would have applied the '*' magic to the pattern "Makefile", while the latter would used no magic to the pattern "*Makefile". Instead, just reserve all non-alnum ASCII letters that are neither glob nor regexp special as potential magic signature, and when we see a magic that is not supported, die with an error message, just like the longhand codepath does. With this, ":%#!*Makefile" will always mean "%#!" magic applied to the pattern "*Makefile", no matter what version of git is used (it is a different matter if the version of git supports all of these three magic matching rules). Also make ':' without anything else to mean "there is no pathspec". This would allow differences between "git log" and "git log ." run from the top level of the working tree (the latter simplifies no-op commits away from the history) to be expressed from a subdirectory by saying "git log :".

2011-04-03compat: add missing #include <sys/resource.h>Libravatar Jonathan Nieder1-0/+1
Starting with commit c793430 (Limit file descriptors used by packs, 2011-02-28), git uses getrlimit to tell how many file descriptors it can use. Unfortunately it does not include the header declaring that function, resulting in compilation errors: sha1_file.c: In function 'open_packed_git_1': sha1_file.c:718: error: storage size of 'lim' isn't known sha1_file.c:721: warning: implicit declaration of function 'getrlimit' sha1_file.c:721: error: 'RLIMIT_NOFILE' undeclared (first use in this function) sha1_file.c:718: warning: unused variable 'lim' The standard header to include for this is <sys/resource.h> (which on some systems itself requires declarations from <sys/types.h> or <sys/time.h>). Probably the problem was missed until now because in current glibc sys/resource.h happens to be included by sys/wait.h. MinGW does not provide sys/resource.h (and compat/mingw takes care of providing getrlimit some other way), so add the missing #include to the "#ifndef __MINGW32__" block in git-compat-util.h.

2011-03-08compat: fall back on __va_copy if availableLibravatar Jonathan Nieder1-1/+10
Since an obvious implementation of va_list is to make it a pointer into the stack frame, implementing va_copy as "dst = src" will work on many systems. Platforms that use something different (e.g., a size-1 array of structs, to be assigned with *(dst) = *(src)) will need some other compatibility macro, though. Luckily, as the glibc manual hints, such systems tend to provide the __va_copy macro (introduced in GCC in March, 1997). By using that if it is available, we can cover our bases pretty well. Discovered by building with CC="gcc -std=c89" on an amd64 machine: $ make CC=c89 strbuf.o [...] strbuf.c: In function 'strbuf_vaddf': strbuf.c:211:2: error: incompatible types when assigning to type 'va_list' from type 'struct __va_list_tag *' make: *** [strbuf.o] Error 1 Explained-by: Junio C Hamano <gitster@pobox.com> Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2011-03-08git-compat-util.h: Honor HP C's noreturn attributeLibravatar Michal Rokos1-1/+4
HP C for Integrity servers (Itanium) gained support for noreturn attribute sometime in 2006. It was released in Compiler Version A.06.10 and made available in July 2006. The __HP_cc define detects the HP C compiler version. Precede the __GNUC__ check so it works well when compiling with HP C using -Agcc option that enables partial support for the GNU C dialect. The -Agcc defines the __GNUC__ too. Signed-off-by: Michal Rokos <michal.rokos@nextsoft.cz> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2011-02-26compat: provide a fallback va_copy definitionLibravatar Jeff King1-0/+4
va_copy is C99. We have avoided using va_copy many times in the past, which has led to a bunch of cut-and-paste. From everything I found searching the web, implementations have historically either provided va_copy or just let your code assume that simple assignment of worked. So my guess is that this will be sufficient, though we won't really know for sure until somebody reports a problem.

2011-02-10compat: helper for detecting unsigned overflowLibravatar Jonathan Nieder1-0/+6
The idiom (a + b < a) works fine for detecting that an unsigned integer has overflowed, but a more explicit unsigned_add_overflows(a, b) might be easier to read. Define such a macro, expanding roughly to ((a) < UINT_MAX - (b)). Because the expansion uses each argument only once outside of sizeof() expressions, it is safe to use with arguments that have side effects.

The odb_mkstemp and odb_pack_keep functions open files under the $GIT_OBJECT_DIRECTORY directory. This requires access to the git configuration which very simple programs do not need.

Syslog does not usually exist on Windows, so implement our own using Window's ReportEvent mechanism. Strings containing "%1" gets expanded into them selves by ReportEvent, resulting in an unreadable string. "%2" and above is not a problem. Unfortunately, on Windows an IPv6 address can contain "%1", so expand "%1" to "% 1" before reporting. "%%1" is also a problem for ReportEvent, but that string cannot occur in an IPv6 address.

Attempting to mmap (via git-add or similar) a file larger than 4GB on 32-bit Linux systems results in a repository that has only the file modulo 4GB stored, because of truncation of the off_t file size to a size_t for mmap. When xsize_t was introduced to handle this truncation in dc49cd7 (Cast 64 bit off_t to 32 bit size_t, 2007-03-06), Shawn even pointed out that it should detect when such a cutoff happens. Make it so.

As on FreeBSD, defining _XOPEN_SOURCE to 600 on DragonFly BSD 2.4-RELEASE or later hides symbols from programs, which leads to implicit declaration of functions, making the return value to be assumed an int. On architectures where sizeof(int) < sizeof(void *), this can cause unexpected behaviors or crashes.
