Instead of piping the rev-list output from its standard input,
you can say:
pack-objects --all --unpacked --revs pack
and feed the rev parameters you would otherwise give the
rev-list on its command line from the standard input.
In other words:
echo 'master..next' | pack-objects --revs pack
and
rev-list --objects master..next | pack-objects pack
are equivalent.

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.

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.

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).

The command unpack-objects dies upon the first error. This is
probably considered a feature -- if a pack is corrupt, instead
of trying to extract from it and possibly risking to contaminate
a good repository with objects whose validity is dubious, we
should seek a good copy of the pack and retry. However, we may
not have any good copy anywhere. This implements the last
resort effort to extract what are salvageable from such a
corrupt pack.
This flag might have helped Sergio when recovering from a
corrupt pack. In my test, it managed to salvage 247 objects out
of a pack that had 251 objects but without it the command
stopped after extracting 73 objects.

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.

If GIT_TRACE is set to an absolute path (starting with a

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

The intention of the test seems to be to build a long chain of
clones that locally borrow objects from their parents and see the
system give up dereferencing long chains. There were two problems:
(1) it did not test the right repository;
(2) it did not build a chain long enough to trigger the limitation.
I do not think it is a good test to make sure the limitation the
current implementation happens to have still exists, but that is
a topic at a totally different level.
At least this fixes the broken test.
