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).

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().

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.

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/

any git commands which rely on perl will print a
human-readable message and exit with an error code.
This patch is based on one from Robin H. Johnson.

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.

Not all OSes use st_ctim and st_mtim in their struct stat. In

This also turns it on by default for OS X (Darwin) machines. Likely

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

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.
This changes the detection logic to see if the given path begins with a
slash.

This commit adds support for relocatable binaries (called
RUNTIME_PREFIX). 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.

If a piece of code wanted to do some cleanup before exiting
(e.g., cleaning up a lockfile or a tempfile), our usual
strategy was to install a signal handler that did something
like this:
do_cleanup(); /* actual work */
signal(signo, SIG_DFL); /* restore previous behavior */
raise(signo); /* deliver signal, killing ourselves */
For a single handler, this works fine. However, if we want
to clean up two _different_ things, we run into a problem.
The most recently installed handler will run, but when it
removes itself as a handler, it doesn't put back the first
handler.
This patch introduces sigchain, a tiny library for handling
a stack of signal handlers. You sigchain_push each handler,

The install target uses a foreach loop to generate a single long shell

maximum length of the argument list varies by platform, and this use of

Rather than using make's foreach loop to pre-generate the shell command
