Makefile: hoist uname autodetection to config.mak.uname Our Makefile first sets up some sane per-platform defaults by looking at "uname", then modifies that according to the results of autoconf (if any), then modifies that according to the user's wishes in config.mak. For sub-Makefiles like Documentation/Makefile, the latter two are available, but the uname defaults are available only to the main Makefile. This hasn't been a problem so far, because the sub-Makefiles do not rely on any of those automatic settings to do their work. This patch puts the uname magic into its own file so it can be reused in other Makefiles, opening up the possibility of new knobs. Note that we leave one reference to uname in the top-level Makefile: if we are on Darwin, we must check the NO_FINK and NO_DARWIN_PORTS settings. But because we are combining uname settings with user-options, we must do so after all of the config is loaded. This is acceptable, as the resulting conditionals are about setting variables specific to the top-level Makefile (and if that ever changes, we can hoist them into a separate post-config include, too).

Portable alloca for Git In the next patch we'll have to use alloca() for performance reasons, but since alloca is non-standardized and is not portable, let's have a trick with compatibility wrappers: 1. at configure time, determine, do we have working alloca() through alloca.h, and define #define HAVE_ALLOCA_H if yes. 2. in code #ifdef HAVE_ALLOCA_H # include <alloca.h> # define xalloca(size) (alloca(size)) # define xalloca_free(p) do {} while(0) #else # define xalloca(size) (xmalloc(size)) # define xalloca_free(p) (free(p)) #endif and use it like func() { p = xalloca(size); ... xalloca_free(p); } This way, for systems, where alloca is available, we'll have optimal on-stack allocations with fast executions. 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.

trace: add high resolution timer function to debug performance issues Add a getnanotime() function that returns nanoseconds since 01/01/1970 as unsigned 64-bit integer (i.e. overflows in july 2554). 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>

strbuf_getwholeline: use getdelim if it is available We spend a lot of time in strbuf_getwholeline in a tight loop reading characters from a stdio handle into a buffer. The libc getdelim() function can do this for us with less overhead. It's in POSIX.1-2008, and was a GNU extension before that. Therefore we can't rely on it, but can fall back to the existing getc loop when it is not available. The HAVE_GETDELIM knob is turned on automatically for Linux, where we have glibc. We don't need to set any new feature-test macros, because we already define _GNU_SOURCE. Other systems that implement getdelim may need to other macros (probably _POSIX_C_SOURCE >= 200809L), but we can address that along with setting the Makefile knob after testing the feature on those systems. Running "git rev-parse refs/heads/does-not-exist" on a repo with an extremely large (1.6GB) packed-refs file went from (best-of-5): real 0m8.601s user 0m8.084s sys 0m0.524s to: real 0m6.768s user 0m6.340s sys 0m0.432s for a wall-clock speedup of 21%.

read-cache: optionally disallow HFS+ .git variants The point of disallowing ".git" in the index is that we would never want to accidentally overwrite files in the repository directory. But this means we need to respect the filesystem's idea of when two paths are equal. The prior commit added a helper to make such a comparison for HFS+; let's use it in verify_path. We make this check optional for two reasons: 1. It restricts the set of allowable filenames, which is unnecessary for people who are not on HFS+. In practice this probably doesn't matter, though, as the restricted names are rather obscure and almost certainly would never come up in practice. 2. It has a minor performance penalty for every path we insert into the index. This patch ties the check to the core.protectHFS config option. Though this is expected to be most useful on OS X, we allow it to be set everywhere, as HFS+ may be mounted on other platforms. The variable does default to on for OS X, though.

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.

Makefile: hoist uname autodetection to config.mak.uname Our Makefile first sets up some sane per-platform defaults by looking at "uname", then modifies that according to the results of autoconf (if any), then modifies that according to the user's wishes in config.mak. For sub-Makefiles like Documentation/Makefile, the latter two are available, but the uname defaults are available only to the main Makefile. This hasn't been a problem so far, because the sub-Makefiles do not rely on any of those automatic settings to do their work. This patch puts the uname magic into its own file so it can be reused in other Makefiles, opening up the possibility of new knobs. Note that we leave one reference to uname in the top-level Makefile: if we are on Darwin, we must check the NO_FINK and NO_DARWIN_PORTS settings. But because we are combining uname settings with user-options, we must do so after all of the config is loaded. This is acceptable, as the resulting conditionals are about setting variables specific to the top-level Makefile (and if that ever changes, we can hoist them into a separate post-config include, too).

msvc: avoid collisions between "tags" and "TAGS" Commit 2f769195 ("MinGW: avoid collisions between "tags" and "TAGS", 28-09-2010) enabled MinGW to use an ETAGS file in order to avoid filename collisions on (Windows) case insensitive filesystems. 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.

msvc: git-daemon: Fix linker "unresolved external" errors 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.

Portable alloca for Git In the next patch we'll have to use alloca() for performance reasons, but since alloca is non-standardized and is not portable, let's have a trick with compatibility wrappers: 1. at configure time, determine, do we have working alloca() through alloca.h, and define #define HAVE_ALLOCA_H if yes. 2. in code #ifdef HAVE_ALLOCA_H # include <alloca.h> # define xalloca(size) (alloca(size)) # define xalloca_free(p) do {} while(0) #else # define xalloca(size) (xmalloc(size)) # define xalloca_free(p) (free(p)) #endif and use it like func() { p = xalloca(size); ... xalloca_free(p); } This way, for systems, where alloca is available, we'll have optimal on-stack allocations with fast executions. 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.

MSVC: link in invalidcontinue.obj for better POSIX compatibility By default, Windows abort()'s instead of setting errno=EINVAL when invalid arguments are passed to standard functions. For example, when PAGER quits and git detects it with errno=EPIPE on write(), check_pipe() in write_or_die.c tries raise(SIGPIPE) but since there is no SIGPIPE on Windows, it is treated as invalid argument, causing abort() and crash report window.

read-cache: optionally disallow NTFS .git variants The point of disallowing ".git" in the index is that we would never want to accidentally overwrite files in the repository directory. But this means we need to respect the filesystem's idea of when two paths are equal. The prior commit added a helper to make such a comparison for NTFS and FAT32; let's use it in verify_path(). We make this check optional for two reasons: 1. It restricts the set of allowable filenames, which is unnecessary for people who are not on NTFS nor FAT32. In practice this probably doesn't matter, though, as the restricted names are rather obscure and almost certainly would never come up in practice. 2. It has a minor performance penalty for every path we insert into the index. This patch ties the check to the core.protectNTFS config option. Though this is expected to be most useful on Windows, we allow it to be set everywhere, as NTFS may be mounted on other platforms. The variable does default to on for Windows, though.

Makefile: hoist uname autodetection to config.mak.uname Our Makefile first sets up some sane per-platform defaults by looking at "uname", then modifies that according to the results of autoconf (if any), then modifies that according to the user's wishes in config.mak. For sub-Makefiles like Documentation/Makefile, the latter two are available, but the uname defaults are available only to the main Makefile. This hasn't been a problem so far, because the sub-Makefiles do not rely on any of those automatic settings to do their work. This patch puts the uname magic into its own file so it can be reused in other Makefiles, opening up the possibility of new knobs. Note that we leave one reference to uname in the top-level Makefile: if we are on Darwin, we must check the NO_FINK and NO_DARWIN_PORTS settings. But because we are combining uname settings with user-options, we must do so after all of the config is loaded. This is acceptable, as the resulting conditionals are about setting variables specific to the top-level Makefile (and if that ever changes, we can hoist them into a separate post-config include, too).

read-cache: optionally disallow NTFS .git variants The point of disallowing ".git" in the index is that we would never want to accidentally overwrite files in the repository directory. But this means we need to respect the filesystem's idea of when two paths are equal. The prior commit added a helper to make such a comparison for NTFS and FAT32; let's use it in verify_path(). We make this check optional for two reasons: 1. It restricts the set of allowable filenames, which is unnecessary for people who are not on NTFS nor FAT32. In practice this probably doesn't matter, though, as the restricted names are rather obscure and almost certainly would never come up in practice. 2. It has a minor performance penalty for every path we insert into the index. This patch ties the check to the core.protectNTFS config option. Though this is expected to be most useful on Windows, we allow it to be set everywhere, as NTFS may be mounted on other platforms. The variable does default to on for Windows, though.

msysgit: Add the --large-address-aware linker directive to the makefile. 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).

Define NO_GETTEXT for Git for Windows The dreaded "your vnsprintf is broken (returned -1)" error is back. At least with the libintl version we have. So for the moment, just work around the issue by _not_ using gettext. Ah, I wish that my attempt at implementing a custom strbuf_vaddf() would not have been brushed aside so rashly. Oh well.
