Commit 83572c1a91 changed many
realloc to xrealloc. This change was made in diff-delta.c too,
although the code can handle an out of memory failure.

This is indeed a good heuristic so here it is. The search always start
with the pack where the last object lookup succeeded. If the wanted
object is not available there then the search continues with the normal
pack ordering.
To test this I split the Linux repository into 66 packs and performed a
"time git-rev-list --objects --all > /dev/null". Best results are as
follows:
Pack Sort w/o this patch w/ this patch
-------------------------------------------------------------
recent objects last 26.4s 20.9s
recent objects first 24.9s 18.4s
This shows that the pack order based on object age has some influence,
but that the last-used-pack heuristic is even more significant in
reducing object lookup.
Signed-off-by: Nicolas Pitre <nico@cam.org> --- Note: the
--max-pack-size to git-repack currently produces packs with old objects
after those containing recent objects. The pack sort based on
filesystem timestamp is therefore backward for those. This needs to be
fixed of course, but at least it made me think about this variable for
the test.

Two issues here:
1) git-repack -a --max-pack-size=10 on the GIT repo dies pretty quick.
There is a lot of confusion about deltas that were suposed to be
reused from another pack but that get stored undeltified due to pack
limit and object size doesn't match entry->size anymore. This test
is not really worth the complexity for determining when it is valid
so get rid of it.
2) If pack limit is reached, the object buffer is freed, including when
it comes from a cached delta data. In practice the object will be
stored in a subsequent pack undeltified, but let's make sure no
pointer to freed data subsists by clearing entry->delta_data.
I also reorganized that code a bit to make it more readable.

If the user has no branches at all (their refs/heads/ is empty)
and they are on a detached HEAD we have a valid repository but
there are no branches to populate into the branch pulldown in
the create branch dialog. Instead of erroring out we can skip

or tags when the user doesn't have any.

Make hexval_table[] "const". Also make sure that the accessor
function hexval() does not access the table with out-of-range
values by declaring its parameter "unsigned char", instead of
"unsigned int".
With this, gcc can just generate:
movzbl (%rdi), %eax
movsbl hexval_table(%rax),%edx
movzbl 1(%rdi), %eax
movsbl hexval_table(%rax),%eax
sall $4, %edx
orl %eax, %edx
for the code to generate a byte from two hex characters.

In this particular location of fsck the index should have already
been opened by verify_pack, which is called just before we get
here and loop through the object names. However, just in case a
future version of that function does not use the index file we'll
double-check its open before we access the num_objects field.

My earlier lazy index opening patch changed this condition to check
index_data and call open_pack_index if it was NULL. In truth we only
care about num_objects. Since open_pack_index does no harm if the
index is already open, and all indexes are likely to be closed in
this application, the "performance optimization" of inlining the
index_data check here was wrong.

My recent patch "Lazily open pack index files on demand" caused a
regression in the case of parsing abbreviated SHA-1 object names.
Git was unable to translate the abbreviated name into the full name
if the object was packed, as the pack .idx files were not opened
before being accessed.
This is a simple test to repack a repository then test for an
abbreviated SHA-1 within the packfile.

Creating deltas between big blobs is a CPU and memory intensive task.
In the writing phase, all (not reused) deltas are redone.
This patch adds support for caching deltas from the deltifing phase, so
that that the writing phase is faster.
The caching is limited to small deltas to avoid increasing memory usage very much.
The implemented limit is (memory needed to create the delta)/1024.

On one particular system I like to keep a cluster of bare Git
repositories and spawn new-workdirs off of them. Since the bare
repositories don't have working directories associated with them
they don't have a .git/ subdirectory that hosts the repository we
are linking to.
Using a bare repository as the backing repository for a workdir
created by this script does require that the user delete core.bare
from the repository's configuration file, so that Git auto-senses
the bareness of a repository based on pathname information, and
not based on the config file.

Reasonably new versions of the cvs CLI client allow one to
specifiy CVS_SERVER as a method variable directly in
CVSROOT. This is way more convinient than using an
environment variable since it gets saved in CVS/Root.
