send-pack: do not send unknown object name from ".have" to pack-objects
test-path-utils: Fix off by one, found by valgrind
get_sha1_basic(): fix invalid memory access, found by valgrind
v1.6.1 introduced ".have" extension to the protocol to allow the receiving
side to advertise objects that are reachable from refs in the repositories
it borrows from. This was meant to be used by the sending side to avoid
sending such objects; they are already available through the alternates
mechanism.
The client side implementation in v1.6.1, which was introduced with
40c155f (push: prepare sender to receive extended ref information from the
receiver, 2008-09-09) aka v1.6.1-rc1~203^2~1, were faulty in that it did
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.

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.

The RUNTIME_PREFIX mechanism allows us to use the default paths on

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.

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.

In a first step, we make all paths relative in the Makefile and

This will be useful when somebody want to checkout something partially from

Modules are interdependent, and you want it to be single repostory (to commit

Other use case is excluding some large blobs.
The quirk for now is that user must specify this option every fetch/rebase;
in other case he may get extra files or "file not found" errors. It may be

DAV-related headers (more specifically, headers related to the lock token,
namely, If, Lock-Token, and Timeout) for curl requests are created and
allocated individually, eg a "if_header" variable for the "If: " header, a
"timeout_header" variable for the "Timeout: " header.
This patch provides a new function ("get_dav_token_headers") that creates
these header, saving methods from allocating memory, and from issuing a
"curl_slist_append()" call. The temporary string storage given to
curl_slist_append() is freed much earlier than the previous code with this
patch, but this change is safe, because curl_slist_append() keeps a copy
of the given string.
In part, this patch also addresses the fact that commit 753bc91 (Remove
the requirement opaquelocktoken uri scheme) did not update memory
allocations for DAV-related headers.
