2009-04-28Makefile: installing git in cygwin 1.7.0Libravatar Eric Blake1-1/+1
On platforms with $X, make removes any leftover scripts 'a' from earlier builds if a new binary 'a.exe' is now built. However, on cygwin 1.7.0, 'git' and 'git.exe' now consistently name the same file. Test for file equality before attempting a remove, in order to avoid nuking just-built binaries.

2009-04-27Makefile: fix NO_PERL bug with gitwebLibravatar Jeff King1-3/+1
When the user has defined NO_PERL, we want to skip building gitweb entirely. However, the conditional to add gitweb/gitweb.cgi to OTHER_PROGRAMS was evaluated before we actually parsed the user's config.mak. This meant that "make NO_PERL=NoThanks" worked fine, but putting "NO_PERL=NoThanks" into your config.mak broke the build (it wanted gitweb.cgi to satisfy "all", but the rule to build it was conditionally ignored, so it complained).

2009-04-25Add an option not to use link(src, dest) && unlink(src) when that is unreliableLibravatar Johannes Schindelin1-0/+8
It seems that accessing NTFS partitions with ufsd (at least on my EeePC) has an unnerving bug: if you link() a file and unlink() it right away, the target of the link() will have the correct size, but consist of NULs. It seems as if the calls are simply not serialized correctly, as single-stepping through the function move_temp_to_file() works flawlessly. As ufsd is "Commertial software" (sic!), I cannot fix it, and have to work around it in Git. At the same time, it seems that this fixes msysGit issues 222 and 229 to assume that Windows cannot handle link() && unlink().

2009-04-20Windows: Skip fstat/lstat optimization in write_entry()Libravatar Johannes Sixt1-0/+9
Commit e4c72923 (write_entry(): use fstat() instead of lstat() when file is open, 2009-02-09) introduced an optimization of write_entry(). Unfortunately, we cannot take advantage of this optimization on Windows because there is no guarantee that the time stamps are updated before the file is closed: "The only guarantee about a file timestamp is that the file time is correctly reflected when the handle that makes the change is closed." (http://msdn.microsoft.com/en-us/library/ms724290(VS.85).aspx) The failure of this optimization on Windows can be observed most easily by running a 'git checkout' that has to update several large files. In this case, 'git checkout' will report modified files, but infact only the timestamps were incorrectly recorded in the index, as can be verified by a subsequent 'git diff', which shows no change. Dmitry Potapov reports the same fix needs on Cygwin; this commit contains his updates for that. Signed-off-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2009-04-08Makefile: allow building without perlLibravatar Jeff King1-2/+25
For systems with a missing or broken perl, it is nicer to explicitly say "we don't want perl" because: 1. The Makefile knows not to bother with Perl-ish things like Git.pm. 2. We can print a more user-friendly error message than "foo is not a git command" or whatever the broken perl might barf 3. Test scripts that require perl can mark themselves and such and be skipped This patch implements parts (1) and (2). The perl/ subdirectory is skipped entirely, gitweb is not built, and any git commands which rely on perl will print a human-readable message and exit with an error code.

This patch implements a new "git bisect--helper" builtin plumbing command that will be used to migrate "git-bisect.sh" to C. We start by implementing only the "--next-vars" option that will read bisect refs from "refs/bisect/", and then compute the next bisect step, and output shell variables ready to be eval'ed by the shell. At this step, "git bisect--helper" ignores the paths that may have been put in "$GIT_DIR/BISECT_NAMES". This will be fixed in a later patch.

2009-03-18MinGW: implement mmapLibravatar Janos Laube1-1/+6
Add USE_WIN32_MMAP which triggers the use of windows' native file memory mapping functionality in git_mmap()/git_munmap() functions. As git functions currently use mmap with MAP_PRIVATE set only, this implementation supports only that mode for now. On Windows, offsets for memory mapped files need to match the allocation granularity. Take this into account when calculating the packed git- windowsize and file offsets. At the moment, the only function which makes use of offsets in conjunction with mmap is use_pack() in sha1-file.c. Git fast-import's code path tries to map a portion of the temporary packfile that exceeds the current filesize, i.e. offset+length is greater than the filesize. The NO_MMAP code worked with that since pread() just reads the file content until EOF and returns gracefully, while MapViewOfFile() aborts the mapping and returns 'Access Denied'. Working around that by determining the filesize and adjusting the length parameter.

2009-03-08Create USE_ST_TIMESPEC and turn it on for DarwinLibravatar Brian Gernhardt1-0/+7
Not all OSes use st_ctim and st_mtim in their struct stat. In particular, it appears that OS X uses st_*timespec instead. So add a Makefile variable and #define called USE_ST_TIMESPEC to switch the USE_NSEC defines to use st_*timespec. This also turns it on by default for OS X (Darwin) machines. Likely this is a sane default for other BSD kernels as well, but I don't have any to test that assumption on.

2009-03-07Record ns-timestamps if possible, but do not use it without USE_NSECLibravatar Kjetil Barvik1-0/+8
Traditionally, the lack of USE_NSEC meant "do not record nor use the nanosecond resolution part of the file timestamps". To avoid problems on filesystems that lose the ns part when the metadata is flushed to the disk and then later read back in, disabling USE_NSEC has been a good idea in general. If you are on a filesystem without such an issue, it does not hurt to read and store them in the cached stat data in the index entries even if your git is compiled without USE_NSEC. The index left with such a version of git can be read by git compiled with USE_NSEC and it can make use of the nanosecond part to optimize the check to see if the path on the filesystem hsa been modified since we last looked at.

This was mostly being tested implicitly by the "http push" tests. But making a separate test script means that: - we will run fetch tests even when http pushing support is not built - when there are failures on fetching, they are easier to see and isolate, as they are not in the middle of push tests This script defaults to running the webserver on port 5550, and puts the original t5540 on port 5540, so that the two can be run simultaneously without conflict (but both still respect an externally set LIB_HTTPD_PORT).

2009-02-20Support coverage testing with GCC/gcovLibravatar Thomas Rast1-0/+24
With gcc's --coverage option, we can perform automatic coverage data collection for the test suite. Add a new Makefile target 'coverage' that scraps all previous coverage results, recompiles git with the required compiler/linker flags (in addition to any flags you specify manually), then runs the test suite and compiles a report. The compilation must be done with all optimizations disabled, since inlined functions (and for line-by-line coverage, also optimized branches/loops) break coverage tracking. The tests are run serially (with -j1). The coverage code should theoretically allow concurrent access to its data files, but the author saw random test failures. Obviously this could be improved. The report currently consists of a list of functions that were never executed during the tests, which is written to 'coverage-untested-functions'. Once this list becomes reasonably short, we would also want to look at branches that were never taken. Currently only toplevel *.c files are considered. It would be nice to at least include xdiff, but --coverage did not save data to subdirectories on the system used to write this (gcc 4.3.2).

The installation rules wanted to differentiate between a template_dir that is given as an absolute path (e.g. /usr/share/git-core/templates) and a relative one (e.g. share/git-core/templates) but it was done by checking if $(abspath $(template_dir)) and $(template_dir) yield the same string. This was wrong in at least two ways. * The user can give template_dir with a trailing slash from the command line to invoke make or from the included config.mak. A directory path ought to mean the same thing with or without such a trailing slash but use of $(abspath) means an absolute path with a trailing slash fails the test. * Versions of GNU make older than 3.81 do not have $(abspath) to begin with.

Such binaries can be moved together with the system configuration files to a different directory, as long as the relative paths from the binary to the configuration files is preserved. This functionality is essential on Windows where we deliver git binaries with an installer that allows to freely choose the installation location. If RUNTIME_PREFIX is unset we use the static prefix. This will be the default on Unix. Thus, the behavior on Unix will remain identical to the old implementation, which used to add the prefix in the Makefile. If RUNTIME_PREFIX is set the prefix is computed from the location of the executable. In this case, system_path() tries to strip known directories that executables can be located in from the path of the executable. If the path is successfully stripped it is used as the prefix. For example, if the executable is "/msysgit/bin/git" and BINDIR is "bin", then the prefix computed is "/msysgit". If the runtime prefix computation fails, we fall back to the static prefix specified in the makefile. This can be the case if the executable is not installed at a known location. Note that our test system sets GIT_CONFIG_NOSYSTEM to tell git to ignore global configuration files during testing. Hence testing does not trigger the fall back. Note that RUNTIME_PREFIX only works on Windows, though adding support on Unix should not be too hard. The implementation requires argv0_path to be set to an absolute path. argv0_path must point to the directory of the executable. We use assert() to verify this in debug builds. On Windows, the wrapper for main() (see compat/mingw.h) guarantees that argv0_path is correctly initialized. On Unix, further work is required before RUNTIME_PREFIX can be enabled.

2009-01-26Move computation of absolute paths from Makefile to runtime (in preparation ↵Libravatar Steffen Prohaska1-16/+26
for RUNTIME_PREFIX) This commit prepares the Makefile for relocatable binaries (called RUNTIME_PREFIX). Such binaries will be able to be moved together with the system configuration files to a different directory, requiring to compute the prefix at runtime. In a first step, we make all paths relative in the Makefile and teach system_path() to add the prefix instead. We used to compute absolute paths in the Makefile and passed them to C as defines. We now pass relative paths to C and call system_path() to add the prefix at runtime.
