Commit 83572c1a914d3f7a8dd66d954c11bbc665b7b923 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 patch reverts this change in diff-delta.c.

Jon Smirl said:
| Once an object reference hits a pack file it is very likely that

| look for an object is the same place the previous object was found.
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.

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

If we are too fast with our changes, the file in
the working copy might still have the same mtime
as noted in the CVS/Entries. This will cause CVS
to happily report to the server that the file is
unmodified which can lead to data loss (and in
our case test failure).
CVS sucks!

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.
Since I only discovered this by accident I guess there
might be others out there that learnt CVS on the 1.11
series (or even earlier) and profit from such a note
about cvs improvements in the last couple years.

There's no point in calculating an MD5 if we're not going to use
it. We'll also avoid the possibility of there being a bug in the
Perl MD5 library not being able to handle zero-sized files.
This is a followup to 20b3d206acbbb042c7ad5f42d36ff8d036a538c5,

Johannes Sixt asked me to try to avoid embedding the runtime location
of git-gui's library directory in the executable script. Not embedding
it helps the MinGW to be relocatable to another directory should a user
wish to install the programs in a directory other than the location the
packager wanted them to be installed into.
Most of this is a hack. We try to determine if the path of our master
git-gui script will be able to locate the lib by ../share/git-gui/lib.
This should be true if $(gitexecdir) and $(libdir) have the same prefix.
If they do then we defer the assignment of $(libdir) until runtime, and
we get it from $argv0 rather than embedding it into the script itself.

Martin Koegler noted that create_delta() performs a new hash lookup
after every block copy encoding which are currently limited to 64KB.
In case of larger identical blocks, the next hash lookup would normally
point to the next 64KB block in the reference buffer and multiple block
copy operations will be consecutively encoded.
It is however possible that the reference buffer be sparsely indexed if
hash buckets have been trimmed down in create_delta_index() when hashing
of the reference buffer isn't well balanced. In that case the hash
lookup following a block copy might fail to match anything and the fact
that the reference buffer still matches beyond the previous 64KB block
will be missed.
Let's rework the code so that buffer comparison isn't bounded to 64KB
anymore. The match size should be as large as possible up front and
only then should multiple block copy be encoded to cover it all.
Also, fewer hash lookups will be performed in the end.
According to Martin, this patch should reduce his 92MB pack down to 75MB
with the dataset he has.
Tests performed on the Linux kernel repo show a slightly smaller pack and
a slightly faster repack.

This just basically creates a "pack_refs()" function that could be used by
anybody. You pass it in the flags you want as a bitmask (PACK_REFS_ALL and
PACK_REFS_PRUNE), and it will do all the heavy lifting.
Of course, it's still static, and it's all in the builtin-pack-refs.c
file, so it's not actually visible to the outside, but the next step would
be to just move it all to a library file (probably refs.c) and expose it.
Then we could easily make "git gc" do this too.
While I did it, I also made it check the return value of the fflush and
fsync stage, to make sure that we don't overwrite the old packed-refs file
with something that got truncated due to write errors!

This means that send-pack and http-push will support pattern refspecs,
so builtin-push.c doesn't have to expand them, and also git push can
just turn --tags into "refs/tags/*", further simplifying
builtin-push.c
check_ref_format() gets a third "conditionally okay" result for
something that's valid as a pattern but not as a particular ref.

If the repository contained an expanded ident keyword (i.e. $Id:XXXX$),
then the wrong bytes were discarded, and the Id keyword was not
expanded. The fault was in convert.c:ident_to_worktree().
Previously, when a "$Id:" was found in the repository version,
ident_to_worktree() would search for the next "$" after this, and
discarded everything it found until then. That was done with the loop:
do {
ch = *cp++;
if (ch == '$')
break;
rem--;
} while (rem);
The above loop left cp pointing one character _after_ the final "$"
(because of ch = *cp++). This was different from the non-expanded case,
were cp is left pointing at the "$", and was different from the comment
which stated "discard up to but not including the closing $". This
patch fixes that by making the loop:
do {
ch = *cp;
if (ch == '$')
break;
cp++;
rem--;
} while (rem);
That is, cp is tested _then_ incremented.
This loop exits if it finds a "$" or if it runs out of bytes in the
source. After this loop, if there was no closing "$" the expansion is
skipped, and the outer loop is allowed to continue leaving this
non-keyword as it was. However, when the "$" is found, size is
corrected, before running the expansion:
size -= (cp - src);
This is wrong; size is going to be corrected anyway after the expansion,
so there is no need to do it here. This patch removes that redundant
correction.
To help find this bug, I heavily commented the routine; those comments
are included here as a bonus.

Under some implementations of echo (such as that provided by
dash), backslash escapes are recognized without any other
options. This means that echo-ing user-supplied strings may
cause any backslash sequences in them to be converted. Using
printf resolves the ambiguity.
This bug can be seen when using git-am to apply a patch
whose subject contains the character sequence "\n"; the
characters are converted to a literal newline. Noticed by
Szekeres Istvan.
