git_connect() can return 0 if we use git protocol for example.
Users of this function don't know and don't care if a process
had been created or not, and to avoid them to check it before
calling finish_connect() this patch allows finish_connect() to
take a null pid. And in that case return 0.
[jc: updated function signature of git_connect() with a comment on
its return value. ]

Use "add_to_string" instead of "sq_quote" and "snprintf", so
that there is no memory allocation and no memory leak.
Also check if the command is too long to fit into the buffer
and die if this is the case, instead of truncating it to the
buffer size.

git_history output is now divided into pages, like git_shortlog,
git_tags and git_heads output. As whole git-rev-list output is now
read into array before writing anything, it allows for better

The function appeared high on a gprof output for a rev-list run of

When we are generating packs to update remote repositories we
want to supply as much information as possible about the revisions
that already exist to rev-list in order optimise the pack as much
as possible. We need to pass two revisions for each branch we are
updating in the remote repository and one for each additional branch.
Where the remote repository has numerous branches we can run out
of command line space to pass them.
Utilise the git-rev-list --stdin mode to allow unlimited numbers
of revision constraints. This allows us to move back to the much
simpler unordered revision selection code.
[jc: added some comments in the code to describe the pipe flow
a bit.]

Avoid failing when cwd is !writable by writing the
packfiles in $GIT_DIR, which is more in line with other commands.
Without this, git-repack was failing when run from crontab
by non-root user accounts. For large repositories, this
also makes the mv operation a lot cheaper, and avoids leaving
temp packfiles around the fs upon failure.

When --stdin option is given, in addition to the <rev>s listed
on the command line, the command can read one rev parameter per
line from the standard input. The list of revs ends at the
first empty line or EOF.
Note that you still have to give all the flags from the command
line; only rev arguments (including A..B, A...B, and A^@ notations)
can be give from the standard input.

setup_revisions() wants to get all the parameters at once and
then postprocesses the resulting revs structure after it is done
with them. This code structure is a bit cumbersome to deal with
efficiently when we want to inject revision parameters from the
side (e.g. read from standard input).
Fortunately, the nature of this postprocessing is not affected by
revision parameters; they are affected only by flags. So it is
Ok to do add_object() after the it returns.
This splits out the code that deals with the revision parameter
out of the main loop of setup_revisions(), so that we can later
call it from elsewhere after it returns.

When build a pack for a push we query the remote copy for existant
heads. These are used to prune unnecessary objects from the pack.
As we receive the remote references in get_remote_heads() we validate
the reference names via check_ref() which includes a length check;
rejecting those >45 characters in size.
This is a miss converted change, it was originally designed to reject
messages which were less than 45 characters in length (a 40 character
sha1 and refs/) to prevent comparing unitialised memory. check_ref()
now gets the raw length so check for at least 5 characters.

This implements a 3-way diff between the HEAD commit, the state in the
index, and the working directory. This is like the n-way diff for a
merge, and uses much of the same code. It is invoked with the -c flag
to git-diff-index, which it already accepted and did nothing with.

Divide page path into directories, so that each part of path links to
the "tree" view of the $hash_base (or HEAD, if $hash_base is not set)
version of the directory.
If the entity is blob, final part (basename) links to $hash_base or
HEAD revision of the "raw" blob ("blob_plain" view). If the entity is
tree, link to the "tree" view.

If you try to fsck a repository that isn't entirely empty, but that has no
inter-object references (ie all the objects are blobs, and don't refer to
anything else), git-fsck-objects currently fails.
This probably cannot happen in practice, but can be tested with something
like
git init-db
touch dummy
git add dummy
git fsck-objects
where the fsck will die by a divide-by-zero when it tries to look up the
references from the one object it found (hash_obj() will do a modulus by
refs_hash_size).
On some other archiectures (ppc, sparc) the divide-by-zero will go
unnoticed, and we'll instead SIGSEGV when we hit the "refs_hash[j]"
access.
So move the test that should protect against this from mark_reachable()
into lookup_object_refs(), which incidentally in the process also fixes
mark_reachable() itself (it used to not mark the one object that _was_
reachable, because it decided that it had no refs too early).

When copying from an existing pack and when copying from a loose
object with new style header, the code makes sure that the piece
we are going to copy out inflates well and inflate() consumes
the data in full while doing so.
The check to see if the xdelta really apply is quite expensive
as you described, because you would need to have the image of
the base object which can be represented as a delta against
something else.

When reusing data from an existing pack and from a new style
loose objects, we used to just copy it staight into the
resulting pack. Instead make sure they are not corrupt, but
do so only when we are not streaming to stdout, in which case
the receiving end will do the validation either by unpacking
the stream or by constructing the .idx file.

If GIT_TRACE is set to an absolute path (starting with a
'/' character), we interpret this as a file path and we
trace into it.
Also if GIT_TRACE is set to an integer value greater than
1 and lower than 10, we interpret this as an open fd value
and we trace into it.
Note that this behavior is not compatible with the
previous one.
We also trace whole messages using one write(2) call to
make sure messages from processes do net get mixed up in
the middle.
This patch makes it possible to get trace information when
running "make test".

Like xmalloc and xrealloc xstrdup dies with a useful message if
the native strdup() implementation returns NULL rather than a
valid pointer.
I just tried to use xstrdup in new code and found it to be missing.
However I expected it to be present as xmalloc and xrealloc are
already commonly used throughout the code.

finding more and more dubious these days.]

Also while we are at it, remove redundant typename[] array from
unpack_sha1_header. The only reason it is different from the
type_names[] array in object.c module is that this code cares
about the subset of object types that are valid in a loose
object, so prepare a separate array of boolean that tells us
which types are valid, and share the name translation with the
others.
