Contribute a fairly paranoid update hook

I'm using a variant of this update hook in a corporate environment
where we perform some validations of the commits and tags that
are being pushed.  The model is a "central repository" type setup,
where users are given access to push to specific branches within
the shared central repository.  In this particular installation we
run a specially patched git-receive-pack in setuid mode via SSH,
allowing all writes into the repository as the repository owner,
but only if this hook blesses it.

One of the major checks we perform with this hook is that the
'committer' line of a commit, or the 'tagger' line of a new annotated
tag actually correlates to the UNIX user who is performing the push.
Users can falsify these lines on their local repositories, but
the central repository that management trusts will reject all such
forgery attempts.  Of course 'author' lines are still allowed to
be any value, as sometimes changes do come from other individuals.

Another nice feature of this hook is the access control lists for
all repositories on the system can also be stored and tracked in
a supporting Git repository, which can also be access controlled
by itself.  This allows full auditing of who-had-what-when-and-why,
thanks to git-blame's data mining capabilities.

Fix overwriting of files when applying contextually independent diffs

Noticed by applying two diffs of different contexts to the same file.

The check for existence of a file was wrong: the test assumed it was
a directory and reset the errno (twice: directly and by calling
lstat). So if an entry existed and was _not_ a directory no attempt
was made to rename into it, because the errno (expected by renaming
code) was already reset to 0. This resulted in error:

    fatal: unable to write file file mode 100644

For Linux, removing "errno = 0" is enough, as lstat wont modify errno
if it was successful. The behavior should not be depended upon,
though, so modify the "if" as well.

Make sure quickfetch is not fooled with a previous, incomplete fetch.

This updates git-rev-list --objects to be a bit more careful
when listing a blob object to make sure the blob actually
exists, and uses it to make sure the quick-fetch optimization we
introduced earlier is not fooled by a previous incomplete fetch.

The quick-fetch optimization works by running this command:

git rev-list --objects <<commit-list>> --not --all

where <<commit-list>> is a list of commits that we are going to
fetch from the other side.  If there is any object missing to
complete the <<commit-list>>, the rev-list would fail and die
(say, the commit was in our repository, but its tree wasn't --
then it will barf while trying to list the blobs the tree
contains because it cannot read that tree).

Usually we do not have the objects (otherwise why would we
fetching?), but in one important special case we do: when the
remote repository is used as an alternate object store
(i.e. pointed by .git/objects/info/alternates).  We could check
.git/objects/info/alternates to see if the remote we are
interacting with is one of them (or is used as an alternate,
recursively, by one of them), but that check is more cumbersome
than it is worth.

The above check however did not catch missing blob, because
object listing code did not read nor check blob objects, knowing
that blobs do not contain any further references to other
objects.  This commit fixes it with practically unmeasurable
overhead.

I've benched this with

git rev-list --objects --all >/dev/null

in the kernel repository, with three different implementations
of the "check-blob".

 - Checking with has_sha1_file() has negligible (unmeasurable)
   performance penalty.

 - Checking with sha1_object_info() makes it somewhat slower,
   perhaps by 5%.

 - Checking with read_sha1_file() to cause a fully re-validation
   is prohibitively expensive (about 4 times as much runtime).

In my original patch, I had this as a command line option, but
the overhead is small enough that it is not really worth it.

Nicolas Pitre [Mon, 16 Apr 2007 16:32:13 +0000 (12:32 -0400)]
pack-objects: better check_object() performances

With large amount of objects, check_object() is really trashing the pack
sliding map and the filesystem cache.  It has a completely random access
pattern especially with old objects where delta replay jumps back and
forth all over the pack.

This patch improves things by:

 1) sorting objects by their offset in pack before calling check_object()
    so the pack access pattern is linear;

 2) recording the object type at add_object_entry() time since it is
    already known in most cases;

 3) recording the pack offset even for preferred_base objects;

 4) avoid calling sha1_object_info() if all possible.

This limits pack accesses to the bare minimum and makes them perfectly
linear.

In the process check_object() was made more clear (to me at least).

Note: I thought about walking the sorted_by_offset list backward in
get_object_details() so if a pack happens to be larger than the available
file cache, then the cache would have been populated with useful data from
the beginning of the pack already when find_deltas() is called.  Strangely,
testing (on Linux) showed absolutely no performance difference.

This is not true if given delta doesn't find its base in the pack though.
But we need that information even for whole object data reuse.

Well in short the current state looks awful and is prone to bugs.  It just
works fine now because try_delta() tests trg_entry->delta before using
trg_entry->delta_size, but that is a bit subtle and I was wondering for a
while why things just worked fine... even if I'm guilty of having

Let's do the sensible thing instead with no ambiguity, which is to have
a separate variable for in_pack_header_size.  This might even help future
optimizations.

Nicolas Pitre [Mon, 16 Apr 2007 16:29:16 +0000 (12:29 -0400)]
pack-objects: rework check_delta_limit usage

Objects that have delta "children" from pack data reuse must consider the
depth of their deepest child when they try to deltify themselves for those
children not to become too deep.

However, in the context of a "thin" pack, the delta children depth was
skipped entirely on the presumption that the pack was always going to be
exploded on the receiving end, hence the delta length wasn't an issue.

Now that we keep received packs as is and reuse pack data when repacking,
those packs do contain delta chains that are longer than expected. Worse,
those delta chain may even grow longer when the pack is further repacked
into another thin pack for a subsequent transmission.

So this patch restores strict delta length even for thin packs, and it
moves check_delta_limit() usage directly in the delta loop where it is
needed.  This way the delta_limit can be removed from struct object_entry
as well.  Oh and the initial value was wrong too.

Expose subprojects as special files to "git diff" machinery

The same way we generate diffs on symlinks as the the diff of text of the
symlink, we can generate subproject diffs (when not recursing into them!)
as the diff of the text that describes the subproject.

Of course, since what descibes a subproject is just the SHA1, that's what
we'll use. Add some pretty-printing to make it a bit more obvious what is
going on, and we're done.

So with this, we can get both raw diffs and "textual" diffs of subproject
changes:

 - git diff --raw:

:160000 160000 2de597b5ad348b7db04bd10cdd38cd81cbc93ab5 0000000... M    sub-A

NOTE! We'll also want to have the ability to recurse into the subproject
and actually diff it recursively, but that will involve a new command line
option (I'd suggest "--subproject" and "-S", but the latter is in use by
pickaxe), and some very different code.

But regardless of ay future recursive behaviour, we need the non-recursive
version too (and it should be the default, at least in the absense of
config options, so that large superprojects don't default to something

Fix some "git ls-files -o" fallout from gitlinks

Since "git ls-files" doesn't really pass down any details on what it
really wants done to the directory walking code, the directory walking
code doesn't really know whether the caller wants to know about gitlink
directories, or whether it wants to just know about ignored files.

So the directory walking code will return those gitlink directories unless
the caller has explicitly told it not to ("dir->show_other_directories"
tells the directory walker to only show "other" directories).

This kind of confuses "git ls-files -o", because
 - it didn't really expect to see entries listed that were already in the
   index, unless they  were unmerged, and would die on that unexpected
   setup, rather than just "continue".
 - it didn't know how to match directory entries with the final "/"

This trivial change updates the "show_other_files()" function to handle
both of these issues gracefully. There really was no reason to die, when
the obviously correct thing for the function was to just ignore files it
already knew about (that's what "other" means here!).

was just a total thinko in the code (we were checking the
filesystem mode against S_IFDIRLNK, which obviously cannot work,

It then re-sends the two patches on top of that, with the fix
for checking out superprojects (we should *not* mess up any
existing subproject directories, certainly not remove them - if
we already have a directory in the place where we now want a
subproject, we should leave it well alone!)
