8ac4838af4 server-info: skip empty lines.
Now we allow an empty line in objects/info/packs file, recognize
that and stop complaining.

21b1aced83 objects/info/packs: work around bug in http-fetch.c::fetch_indices()
The code to fetch pack index files in deployed clients have a
bug that causes it to ignore the pack file on the last line of
objects/info/packs file, so append an empty line to work it
around.

2dee581667 qsort(): ptrdiff_t may be larger than int
This is a companion patch to e23eff8be9
commit.  The same logic, the same rationale that a comparison
function that returns an int should not just compute a ptrdiff_t
and return it.

3e15c67c90 server-info: throw away T computation as well.
Again, dumb transport clients are too dumb to make use of the
top objects information to make a choice among multiple packs,
so computing these lines are useless for now.  We could
resurrect them if needed later.  Also dumb transport clients
presumably can do their own approximation by downloading idx
files to see how relevant each pack is for their fetch.

d5eac49868 server-info: stop sorting packs by latest date.
This does not seem to buy us much, for the same reason as the
previous change.  Dumb clients are still too dumb.

6f42f89c1f server-info.c: drop unused D lines.
We tried to compute pack interdependency information in
$GIT_DIR/objects/info/packs, hoping that dumb transports would
make use of it when choosing from multiple choice, but that has
never materialized, so stop computing D lines for now.

4a4e6fd74f Rework object refs tracking to reduce memory usage
Store pointers to referenced objects in a variable sized array instead
of linked list.  This cuts down memory usage of utilities which use
object references; e.g., git-fsck-objects --full on the git.git
repository consumes about 2 MB of memory tracked by Massif instead of
7 MB before the change.  Object refs are still the biggest consumer of
memory (57%), but the malloc overhead for a single block instead of a
linked list is substantially smaller.

9534f40bc4 Be careful when dereferencing tags.
One caller of deref_tag() was not careful enough to make sure
what deref_tag() returned was not NULL (i.e. we found a tag
object that points at an object we do not have).  Fix it, and
warn about refs that point at such an incomplete tag where
needed.

f6b42a81fd Show peeled onion from upload-pack and server-info.
This updates git-ls-remote to show SHA1 names of objects that are
referred by tags, in the "ref^{}" notation.

This would make git-findtags (without -t flag) almost trivial.

    git-peek-remote . |
    sed -ne "s:^$target	"'refs/tags/\(.*\)^{}$:\1:p'

Also Pasky could do:

    git-ls-remote --tags $remote |
    sed -ne 's:\(	refs/tags/.*\)^{}$:\1:p'

to find out what object each of the remote tags refers to, and
if he has one locally, run "git-fetch $remote tag $tagname" to
automatically catch up with the upstream tags.

60d0526aaa Unoptimize info/refs creation.
The code did not catch the case where you removed an existing ref
without changing anything else.  We are not talking about hundreds of
refs anyway, so remove that optimization.

2c04662d89 Revert "Replace zero-length array decls with []."
This reverts 6c5f9baa3b commit, whose
change breaks gcc-2.95.

Not that I ignore portability to compilers that are properly C99, but
keeping compilation with GCC working is more important, at least for
now.  We would probably end up declaring with "name[1]" and teach the
allocator to subtract one if we really aimed for portability, but that
is left for later rounds.

undeclared variables with global scope.

8f3f9b09dc [PATCH] Add update-server-info.
The git-update-server-info command prepares informational files
to help clients discover the contents of a repository, and pull
from it via a dumb transport protocols.  Currently, the
following files are produced.

 - The $repo/info/refs file lists the name of heads and tags
   available in the $repo/refs/ directory, along with their
   SHA1.  This can be used by git-ls-remote command running on
   the client side.

 - The $repo/info/rev-cache file describes the commit ancestry
   reachable from references in the $repo/refs/ directory.  This
   file is in an append-only binary format to make the server
   side friendly to rsync mirroring scheme, and can be read by
   git-show-rev-cache command.

 - The $repo/objects/info/pack file lists the name of the packs
   available, the interdependencies among them, and the head
   commits and tags contained in them.  Along with the other two
   files, this is designed to help clients to make smart pull
   decisions.

The git-receive-pack command is changed to invoke it at the end,
so just after a push to a public repository finishes via "git
push", the server info is automatically updated.

In addition, building of the rev-cache file can be done by a
standalone git-build-rev-cache command separately.
