| * date: recognize bogus FreeBSD gmtime outputJeff King2014-04-01
| | | | | | | | | | | | | | | | | | | | | | | | | | Most gmtime implementations return a NULL value when they encounter an error (and this behavior is specified by ANSI C and POSIX). FreeBSD's implementation, however, will simply leave the "struct tm" untouched. Let's also recognize this and convert it to a NULL (with this patch, t4212 should pass on FreeBSD).

However, we already have get_be32, which has a few advantages: 1. It's already written, so we avoid duplication. 2. It's probably faster, since it does the endian conversion and the alignment fix at the same time. 3. The get_be32 code is well-tested, having been in block-sha1 for a long time. By contrast, our custom helpers were probably almost never used, since the user needed to manually define a macro to enable them. We have to add a get_be16 implementation to the existing get_be32, but that is very simple to do. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

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.

When we remove these definitions, the only problem we get is "warning C4005: '_stati64' : macro redefinition" for this line in mingw.h: #define _stati64(x,y) mingw_stat(x,y) The reason is that as of MSVCR80.dll (distributed with MSVC 2005), the original _stati64 family of functions was renamed to _stat32i64, and the former function names became macros (pointing to the appropriate function based on the definition of _USE_32BIT_TIME_T). Defining _stati64 works on MinGW because MinGW by default compiles against the MSVCRT.DLL that is part of Windows (i.e. _stati64 is a function rather than a macro). Note: MinGW *can* compile for newer MSVC runtime versions, and MSVC apparently can also compile for the Windows MSVCRT.DLL via the DDK (see http://www.syndicateofideas.com/posts/fighting-the-msvcrt-dll-hell ). Remove the stat definitions from msvc.h, as they are not compiler related. In mingw.h, determine the runtime version in use from the definitions of _stati64 and _USE_32BIT_TIME_T, and define stat() accordingly. This also fixes that stat() in MSVC builds still resolves to mingw_lstat() instead of mingw_stat().

This removes it and uses the standard lstat() that comes with Cygwin. Recent topic that uses lstat on packed-refs file is broken when this cheating lstat is used, and this is a simplest fix that is also the cleanest direction to go in the long run. * rj/cygwin-clarify-use-of-cheating-lstat: cygwin: Remove the Win32 l/stat() implementation

In order to handle absolute paths, cygwin mount points and symbolic links, this implementation may fall back on the standard cygwin l/stat() functions. Also, the choice of cygwin or Win32 functions is made lazily (by the first call(s) to l/stat) based on the state of some config variables. Unfortunately, this "schizophrenic stat" implementation has been the source of many problems ever since. For example, see commits 7faee6b8, 79748439, 452993c2, 085479e7, b8a97333, 924aaf3e, 05bab3ea and 0117c2f0. In order to avoid further problems, such as the issue raised by the new reference handling API, remove the Win32 l/stat() implementation.

The solution involved using a new build variable (V15_MINGW_HEADERS) to conditionally compile the cygwin.c source file to use an include order appropriate for the old and new header files. (The build variable was later renamed in commit 9fca6cff to CYGWIN_V15_WIN32API). The include order used for cygwin 1.7 includes the "win32.h" header before "../git-compat-util.h". This order was problematic on cygwin 1.5, since it lead to the WIN32 symbol being defined along with the inclusion of some WIN32 API headers (e.g. <winsock2.h>) which cause compilation errors. The header include order problem on cygwin 1.5 has since been fixed (see commit "mingw: rename WIN32 cpp macro to GIT_WINDOWS_NATIVE"), so we can now remove the conditional compilation along with the associated CYGWIN_V15_WIN32API build variable.

On Cygwin, most of the time git can pretend this is just another Unix machine, and Windows-specific magic is generally counterproductive. Unfortunately Cygwin *does* define the WIN32 symbol in some headers. Best to rely on a new git-specific symbol GIT_WINDOWS_NATIVE instead, defined as follows: #if defined(WIN32) && !defined(__CYGWIN__) # define GIT_WINDOWS_NATIVE #endif After this change, it should be possible to drop the CYGWIN_V15_WIN32API setting without any negative effect.

The original main function is effectively renamed to 'mingw_main' and is called from the new main function. The replacement main is used to execute certain actions common to all git programs on MinGW (e.g. ensure the standard I/O streams are in binary mode). In order to suppress the errors, we change the macro to include the parameters in the declaration of the mingw_main function. Unfortunately, this change provokes both sparse and gcc to complain about 9 calls to mingw_main(), such as the following: CC git.o git.c: In function 'main': git.c:510: warning: passing argument 2 of 'mingw_main' from \ incompatible pointer type git.c:510: note: expected 'const char **' but argument is of \ type 'char **' In order to suppress these warnings, since both of the main functions need to be declared with the same prototype, we change the declaration of the 9 main functions, thus: int main(int argc, char **argv) Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk> Signed-off-by: Junio C Hamano <gitster@pobox.com>

The 'pinfo' variable does not require more than file scope, so we simply add the static modifier to the declaration. The 'pinfo_cs' variable, in contrast, requires initialisation in the mingw replacement main() function, so we add an extern declaration to the compat/mingw.h header file. The remaining warning is suppressed by replacing the rhs of the pointer assignment with the NULL pointer literal.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sparse issues two 'Using plain integer as NULL pointer' warnings against the call to the CreateFileMapping() function. The warnings relate to the second and sixth parameters, which both have pointer type. In order to suppress the warnings, we simply pass the NULL pointer, rather than '0', to those parameters in the function call.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sparse issues an 'Using plain integer as NULL pointer' warning when passing the constant '0' as the second parameter in the call to the WSAEventSelect() function. The function parameter has a pointer type (WSAEVENT, aka HANDLE, aka void *) so that, in order to suppress the warning, we simply pass NULL for that parameter in the function call expression.

The first field of the pthread_t structure has type HANDLE (void *), so in order to suppress the warning, we replace the initializer expression with '{ NULL }'.

Unfortunately, on MinGW, this provokes sparse to issue the following warning: compat/unsetenv.c:5:20: warning: non-ANSI function declaration of \ function '__p__environ' On MinGW, the <stdlib.h> header defines the 'environ' symbol as a preprocessor macro (via _environ) which obtains the environ table pointer via a call to the __p__environ() function. In order to suppress the warning, we simply remove the redundant declaration of the 'environ' symbol, since the symbol is already declared correctly in <stdlib.h> (included via git-compat-util.h).

The declaration can be enabled by defining the _GNU_SOURCE symbol prior to including certain system header files. In particular, it may not be sufficient to simply define _GNU_SOURCE just prior to including the <sys/mman.h> header. (e.g. defining the symbol after including <sys/types.h> will be completely ineffective.) In order to suppress the warnings, we define the _GNU_SOURCE symbol at the start of the malloc.c.h header file.

In addition, sparse issues some "non-ANSI function declaration" type warnings for the symbols 'win32_getcurrentthreadid', 'malloc_stats' and 'malloc_footprint'. In order to suppress the NULL pointer warnings, rather than replace all uses of '0' as a null pointer representation with NULL, we add -Wno-non-pointer-null to SPARSE_FLAGS while checking nedmalloc.c. In order to suppress the "non-ANSI function declaration" warnings, we simply include the missing 'empty parameter list' prototype (void) in the function declarations.
