Teach rsync transport about alternates.
For local operations and downloading and uploading via git aware protocols,
use of $GIT_OBJECT_DIRECTORY/info/alternates is recommended on the server
side for big projects that are derived from another one (like Linux kernel).
However, dumb protocols and rsync transport needs to resolve this on the
client end, which we did not bother doing until this week.
I noticed we use "rsync -z" but most of our payload is already compressed,
which was not quite right. This commit also fixes it.

[PATCH] Avoid building object ref lists when not needed
The object parsing code builds a generic "this object references that
object" because doing a full connectivity check for fsck requires it.
However, nothing else really needs it, and it's quite expensive for
git-rev-list that can have tons of objects in flight.
So, exactly like the commit buffer save thing, add a global flag to
disable it, and use it in git-rev-list.
Before:
$ /usr/bin/time git-rev-list --objects v2.6.12..HEAD | wc -l
12.28user 0.29system 0:12.57elapsed 99%CPU (0avgtext+0avgdata 0maxresident)k
0inputs+0outputs (0major+26718minor)pagefaults 0swaps
59124
After this change:
$ /usr/bin/time git-rev-list --objects v2.6.12..HEAD | wc -l
10.33user 0.18system 0:10.54elapsed 99%CPU (0avgtext+0avgdata 0maxresident)k
0inputs+0outputs (0major+18509minor)pagefaults 0swaps
59124
and note how the number of pages touched by git-rev-list for this
particular object list has shrunk from 26,718 (104 MB) to 18,509 (72 MB).
Calculating the total object difference between two git revisions is still
clearly the most expensive git operation (both in memory and CPU time),
but it's now less than 40% of what it used to be.

That's still a honking big memory footprint, but it's about half of what

[PATCH] Re-organize "git-rev-list --objects" logic
The logic to calculate the full object list used to be very inter-twined

For no good reason - it's actually a lot simpler to just do that logic

This improves performance a bit, and uses slightly less memory in my
tests, but more importantly it makes the code simpler to work with and
follow what it does.
The performance win is less than I had hoped for, but I get:

ie it improved by 2 seconds, and took a 5000+ fewer pages (hey, that's
20MB out of 174MB to go). And got the same number of objects (in theory,
the more expensive one might find some more shared objects to avoid. In
practice it obviously doesn't).
I know how to make it use _lots_ less memory, which will probably speed it
up. But that's for another time, and I'd prefer to see this go in first.

[PATCH] Avoid wasting memory in git-rev-list
As pointed out on the list, git-rev-list can use a lot of memory.
One low-hanging fruit is to free the commit buffer for commits that we
parse. By default, parse_commit() will save away the buffer, since a lot
of cases do want it, and re-reading it continually would be unnecessary.
However, in many cases the buffer isn't actually necessary and saving it
just wastes memory.
We could just free the buffer ourselves, but especially in git-rev-list,
we actually end up using the helper functions that automatically add
parent commits to the commit lists, so we don't actually control the
commit parsing directly.
Instead, just make this behaviour of "parse_commit()" a global flag.
Maybe this is a bit tasteless, but it's very simple, and it makes a
noticable difference in memory usage.

[PATCH] Define relative .git/objects/info/alternates semantics.
An entry in the alternates file can name a directory relative to
the object store it describes. A typical linux-2.6 maintainer
repository would have "../../../torvalds/linux-2.6.git/objects" there,
because the subsystem maintainer object store would live in
/pub/scm/linux/kernel/git/$u/$system.git/objects/
and the object store of Linus tree is in
/pub/scm/linux/kernel/git/torvalds/linux-2.6.git/objects/
This unfortunately is different from GIT_ALTERNATE_OBJECT_DIRECTORIES
which is relative to the cwd of the running process, but there is no
way to make it consistent with the behaviour of the environment
variable. The process typically is run in $system.git/ directory for
a naked repository, or one level up for a repository with a working
tree, so we just define it to be relative to the objects/ directory
to be different from either ;-).
Later, the dumb transport could be updated to read from info/alternates
and make requests for the repository the repository borrows from.

[PATCH] Make 'git checkout' a bit more forgiving when switching branches.
If you make a commit on a path, and then make the path
cache-dirty afterwards without changing its contents, 'git
checkout' to switch to another branch is prevented because
switching the branches done with 'read-tree -m -u $current
$next' detects that the path is cache-dirty, but it does not
bother noticing that the contents of the path has not been
actualy changed.
Since switching branches would involve checking out paths
different in the two branches, hence it is reasonably expensive
operation, we can afford to run update-index before running
read-tree to reduce this kind of false change from triggering
the check needlessly.

Multi-backend merge driver.
The new command 'git merge' takes the current head and one or more
remote heads, with the commit log message for the automated case.
If the heads being merged are simple fast-forwards, it acts the
same way as the current 'git resolve'. Otherwise, it tries
different merge strategies and takes the result from the one that
succeeded auto-merging, if there is any.
If no merge strategy succeeds auto-merging, their results are
evaluated for number of paths needed for hand resolving, and the
one with the least number of such paths is left in the working
tree. The user is asked to resolve them by hand and make a
commit manually.
The calling convention from the 'git merge' driver to merge
strategy programs is very simple:
- A strategy program is to be called 'git-merge-<strategy>'.
- They take input of this form:
<common1> <common2> ... '--' <head> <remote1> <remote2>...
That is, one or more the common ancestors, double dash, the
current head, and one or more remote heads being merged into
the current branch.
- Before a strategy program is called, the working tree is
matched to the current <head>.
- The strategy program exits with status code 0 when it
successfully auto-merges the given heads. It should do
update-cache for all the merged paths when it does so -- the
index file will be used to record the merge result as a
commit by the driver.
- The strategy program exits with status code 1 when it leaves
conflicts behind. It should do update-cache for all the
merged paths that it successfully auto-merged, and leave the
cache entry in the index file as the same as <head> for paths
it could not auto-merge, and leave its best-effort result
with conflict markers in the working tree when it does so.
- The strategy program exists with status code other than 0 or
1 if it does not handle the given merge at all.
As examples, this commit comes with merge strategies based on
'git resolve' and 'git octopus'.

Keep bisection log so that it can be replayed later.
The 'git bisect' command was very unforgiving in that once you made a
mistake telling it good/bad it was very hard to take it back. Keep a
log of what you told it in an earlier session, so that it can be
replayed after removing everything after what you botched last time.

Fix copy marking from diffcore-rename.
When (A,B) ==> (B,C) rename-copy was detected, we incorrectly said
that C was created by copying B. This is because we only check if the
path of rename/copy source still exists in the resulting tree to see
if the file is renamed out of existence. In this case, the new B is
created by copying or renaming A, so the original B is lost and we
should say C is a rename of B not a copy of B.

[PATCH] archimport - add merge detection
We now keep track of the patches merged in each branch since they have
diverged, using the records that the Arch "logs" provide. Merge parents
for a commit are defined if we are merging a series of patches that starts
from the mergebase.
If patches from a related branch are merged out-of-order, we keep track of
how much has been merged sequentially -- the tip of that sequential merge
is our new parent from that branch.
This mechanism works very well for branches that merge in dovetail and/or
flying fish patterns, probably less well for others.

that can be reachable from other commits, to make detection of
fast forward condition in multi-head merge easier.

'build' scripts before installing.
Earlier we renamed git-foo.sh to git-foo while installing, which
was mostly done by inertia than anything else. This however
made writing tests to use scripts harder.
This patch builds the scripts the same way as we build binaries
from their sources. As a side effect, you can now specify
non-standard paths you have your Perl binary is in when running
the make.

[PATCH] git-daemon --inetd
git-daemon using inetd. does not work properly. inetd routes stderr onto the
network line just like stdout, which was apparently not expected to be so.
As the result of this, the stream is closed by the receiver, because some
"Packing %d objects\n" originating from pack_objects is first reported over
the line instead of the expected pack_header, and so the SIGNATURE test
fails. Here is a workaround.

Big tool rename.
As promised, this is the "big tool rename" patch. The primary differences
since 0.99.6 are:
(1) git-*-script are no more. The commands installed do not
have any such suffix so users do not have to remember if
something is implemented as a shell script or not.
(2) Many command names with 'cache' in them are renamed with
'index' if that is what they mean.
There are backward compatibility symblic links so that you and
Porcelains can keep using the old names, but the backward
compatibility support is expected to be removed in the near
future.
