Disable gitunsetenv in the Makefile and use env_setenv (via mingw_putenv) instead (this frees removed environment entries). Move xstrdup from env_setenv to make_augmented_environ, so that mingw_putenv no longer copies the environment entries (according to POSIX [1], "the string [...] shall become part of the environment"). This also fixes the memory leak in gitsetenv, which expects a POSIX compliant putenv. [1] http://pubs.opengroup.org/onlinepubs/009695399/functions/putenv.html Note: This patch depends on taking control of char **environ and having our own mingw_putenv (both introduced in "Win32: Unicode environment (incoming)").

This is easier to work with than e.g. struct timeval or struct timespec. Basing the timer on the epoch allows using the results with other time-related APIs. To simplify adaption to different platforms, split the implementation into a common getnanotime() and a platform-specific highres_nanos() function. The common getnanotime() function handles errors, falling back to gettimeofday() if highres_nanos() isn't implemented or doesn't work. getnanotime() is also responsible for normalizing to the epoch. The offset to the system clock is calculated only once on initialization, i.e. manually setting the system clock has no impact on the timer (except if the fallback gettimeofday() is in use). Git processes are typically short lived, so we don't need to handle clock drift. The highres_nanos() function returns monotonically increasing nanoseconds relative to some arbitrary point in time (e.g. system boot), or 0 on failure. Providing platform-specific implementations should be relatively easy, e.g. adapting to clock_gettime() as defined by the POSIX realtime extensions is seven lines of code. This version includes highres_nanos() implementations for: * Linux: using clock_gettime(CLOCK_MONOTONIC) * Windows: using QueryPerformanceCounter() Todo: * enable clock_gettime() on more platforms * add Mac OSX version, e.g. using mach_absolute_time + mach_timebase_info Signed-off-by: Karsten Blees <blees@dcon.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Recent Cygwin does offer usable pread() and we enabled multi-threading with 103d530f (Cygwin 1.7 has thread-safe pread, 2013-07-19). Work around this problem on platforms with a thread-unsafe pread() emulation by opening one file handle per thread; it would prevent parallel pread() on different file handles from stepping on each other. Also remove NO_THREAD_SAFE_PREAD that was introduced in c0f8654 because it's no longer used anywhere. This workaround is unconditional, even for platforms with thread-safe pread() because the overhead is small (a couple file handles more) and not worth fragmenting the code.

In MINGW, malloc.h has explicit check for GNUC and if it is so, defines alloca to __builtin_alloca, so it looks like we don't need to add any code to here-shipped alloca.h to get optimum performance.

On the other hand, on systems, where alloca is not available, this gracefully fallbacks to xmalloc/free. Both autoconf and config.mak.uname configurations were updated. For autoconf, we are not bothering considering cases, when no alloca.h is available, but alloca() works some other way - its simply alloca.h is available and works or not, everything else is deep legacy. For config.mak.uname, I've tried to make my almost-sure guess for where alloca() is available, but since I only have access to Linux it is the only change I can be sure about myself, with relevant to other changed systems people Cc'ed. NOTE SunOS and Windows had explicit -DHAVE_ALLOCA_H in their configurations. I've changed that to now-common HAVE_ALLOCA_H=YesPlease which should be correct.

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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This has the effect of increasing the address space from 2GB to 4GB under 64-bit Windows, reducing the likelihood of an "out of memory" error when e.g. repacking a large repository. The test suite passes with this patch, with and without the MEM_TOP_DOWN flag added to all VirtualAlloc calls. While this is no guarantee that there are no issues with large memory support (it could break Git on other setups than mine, for example), it at least increases the chance that nothing obvious goes wrong (such as errors introduced by faulty sign extension, say, with ssize_t).

In addition, this prevents 'make' from issuing several warning messages. When using the Makefile to perform an MSVC build, which is usually executed using MinGW tools, we can also benefit from this capability. In order to reap the above benefits, we set the ETAGS_TARGET build variable to ETAGS in the MSVC config block.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In particular, while linking test-svn-fe.exe, the linker complains that the external symbol _strtoull is unresolved. A call to this function was added in commit ddcc8c5b ("vcs-svn: skeleton of an svn delta parser", 25-12-2010). The NO_STRTOULL build variable attempts to provide support to old systems which can't even declare 'unsigned long long' variables, let alone provide the strtoll() or strtoull() functions. Setting this build variable does not provide an implementation of these functions. Rather, it simply allows the compat implementations of strto{i,u}max() to use strtol() and strtoul() instead. In order to fix the linker error on systems with NO_STRTOULL set, currently MSVC and OSF1, we can substitute a call to strtoumax(). However, we can easily provide support for the strtoull() and strtoll() functions on MSVC, since they are essentially already available as _strtoui64() and _strtoi64(). This allows us to remove NO_STRTOULL for MSVC. Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk> Tested-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In particular, while linking git-daemon.exe, the linker complains that the external symbols _inet_pton and _inet_ntop are unresolved. Commit a666b472 ("daemon: opt-out on features that require posix", 04-11-2010) addressed this problem for MinGW by configuring the use of the internal 'compat' versions of these function. Although the MSVC header <WS2tcpip.h> contains the prototypes for the inet_pton and inet_ntop functions, they are only visible for Windows API versions from 0x0600 (Windows Vista) or later. (In addition, on Windows XP, ws2_32.dll does not export these symbols). In order to fix the linker errors, we also configure the MSVC build to use the internal compat versions of these functions by setting the NO_INET_{PTON,NTOP} build variables.
