The parameter n of unpack_callback() can have a value of up to
MAX_UNPACK_TREES. The check at the top of unpack_trees() (its only
(indirect) caller) makes sure it cannot exceed this limit.
unpack_callback() passes it and the array src to unpack_nondirectories(),
which has this loop:
for (i = 0; i < n; i++) {
/* ... */
src[i + o->merge] = o->df_conflict_entry;
o->merge can be 0 or 1, so unpack_nondirectories() potentially accesses
the array src at index MAX_UNPACK_TREES. This patch makes it big enough.

git-cvsserver: run post-update hook *after* update.
CVS server was running the hook before the update action was
actually done. This performs the update before the hook is called.
The original commit that introduced the current incorrect behavior
was 394d66d "git-cvsserver runs hooks/post-update". The error in
ordering of the hook call appears to have gone unnoticed, but since
git-cvsserver is supposed to emulate receive-pack, it stands to
reason that the hook should be run *after* the update. Since this
behavior is inconsistent with recieve-pack, users are either:
1) not using post-update hooks with git-cvsserver;
2) using post-update hooks that don't care whether they are
called before or after the actual update occurs;
3) using post-update hooks *only* with git-cvsserver, and
relying on the hook being called just before the update.
This patch would affect only users in case 3. These users are
depending on fairly obviously wrong behavior, and moreover they can
simply change their current post-update into post-recieve hooks,
and their systems will work correctly again.

The signal tests consists of checking that each of our

However, some platforms (notably Solaris) will default
SIGINT to SIG_IGN if there is no controlling terminal. In

revision traversal: allow UNINTERESTING objects to be missing
Most of the existing codepaths were meant to treat missing uninteresting
objects to be a silently ignored non-error, but there were a few places
in handle_commit() and add_parents_to_list(), which are two key functions
in the revision traversal machinery, that cared:
- When a tag refers to an object that we do not have, we barfed. We
ignore such a tag if it is painted as UNINTERESTING with this change.
- When digging deeper into the ancestry chain of a commit that is already
painted as UNINTERESTING, in order to paint its parents UNINTERESTING,
we barfed if parse_parent() for a parent commit object failed. We can
ignore such a parent commit object.
Update usage statement to remove a no-longer supported option, and to hide two
options (one a no-op, one internal) unless --help-all is used.

The last test case checks whether unpacked objects receive the time stamp
of the pack file. Due to different implementations of stat(2) by MSYS and
our version in compat/mingw.c, the test fails in about half of the test
runs.
Note the following facts:
- The test uses perl's -M operator to compare the time stamps. Since we
depend on MSYS perl, the result of this operator is based on MSYS's
implementation of the stat(2) call.
- NTFS on Windows records fractional seconds.
- The MSYS implementation of stat(2) *rounds* fractional seconds to full
seconds instead of truncating them. This becomes obvious by comparing the
modification times reported by 'ls --full-time $f' and 'stat $f' for
various files $f.
- Our implementation of stat(2) in compat/mingw.c *truncates* to full
seconds.
The consequence of this is that
- add_packed_git() picks up a truncated whole second modification time
from the pack file time stamp, which is then used for the loose objects,
while the pack file retains its time stamp in fractional seconds;
- but the test case compared the pack file's rounded modification times
to the loose objects' truncated modification times.
And half of the time the rounded modification time is not the same as its
truncated modification time.
The fix is that we replace perl by 'test-chmtime -v +0', which prints the
truncated whole-second mtime without modifying it.

v1.6.1 introduced ".have" extension to the protocol to allow the receiving

not consider the possiblity that the repository receiver borrows from
might have objects it does not know about.
This fixes it by refraining from passing missing commits to underlying
pack-objects. Revision machinery may need to be tightened further to
treat missing uninteresting objects as non-error events, but this is an
obvious and safe fix for a maintenance release that is almost good enough.

diff.c: output correct index lines for a split diff
A patch that changes the filetype (e.g. regular file to symlink) of a path
must be split into a deletion event followed by a creation event, which
means that we need to have two independent metainfo lines for each.
However, the code reused the single set of metainfo lines.
As the blob object names recorded on the index lines are usually not used
nor validated on the receiving end, this is not an issue with normal use
of the resulting patch. However, when accepting a binary patch to delete
a blob, git-apply verified that the postimage blob object name on the
index line is 0{40}, hence a patch that deletes a regular file blob that
records binary contents to create a blob with different filetype (e.g. a
symbolic link) failed to apply. "git am -3" also uses the blob object
names recorded on the index line, so it would also misbehave when
synthesizing a preimage tree.
This moves the code to generate metainfo lines around, so that two
independent sets of metainfo lines are used for the split halves.

Compute prefix at runtime if RUNTIME_PREFIX is set
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.

Modify setup_path() to only add git_exec_path() to PATH
Searching git programs only in the highest priority location is
sufficient. It does not make sense that some of the required
programs are located at the highest priority location but other
programs are picked up from a lower priority exec-path. If
exec-path is overridden a complete set of commands should be
provided, otherwise several different versions could get mixed,
which is likely to cause confusion.
If a user explicitly overrides the default location (by --exec-path
or GIT_EXEC_PATH), we now expect that all the required programs are
found there. Instead of adding the directories "argv_exec_path",
"getenv(EXEC_PATH_ENVIRONMENT)", and "system_path(GIT_EXEC_PATH)"
to PATH, we now rely on git_exec_path(), which implements the same
order, but only returns the highest priority location to search for
executables.
Accessing only the location with highest priority is also required
for testing executables built with RUNTIME_PREFIX. The call to
system_path() should be avoided if RUNTIME_PREFIX is set and the
executable is not installed at its final destination. Because we
test before installing, we want to avoid calling system_path()
during tests. The modifications in this commit avoid calling
system_path(GIT_EXEC_PATH) if a higher-priority location is
provided, which is the case when running the tests.
