[PATCH] fetch.c: Remove call to parse_object() from process()
The call to parse_object() in process() is not actually needed - if
the object type is unknown, parse_object() will be called by loop();
if the type is known, the object will be parsed by the appropriate
process_*() function.
After this change blobs which exist locally are no longer parsed,
which gives about 2x CPU usage improvement; the downside is that there
will be no warnings for existing corrupted blobs, but detecting such
corruption is the job of git-fsck-objects, not the fetch programs.
Newly fetched objects are still checked for corruption in http-fetch.c
and ssh-fetch.c (local-fetch.c does not seem to do it, but the removed
parse_object() call would not be reached for new objects anyway).

[PATCH] fetch.c: Make process() look at each object only once
The process() function is very often called multiple times for the
same object (because lots of trees refer to the same blobs), but did
not have a fast check for this, therefore a lot of useless calls to
has_sha1_file() and parse_object() were made before discovering that
nothing needs to be done.
This patch adds the SEEN flag which is used in process() to make it
look at each object only once. When testing git-local-fetch on the
repository of GIT, this gives a 14x improvement in CPU usage (mainly
because the redundant calls to parse_object() are now avoided -
parse_object() always unpacks and parses the object data, even if it
was already parsed before).

[PATCH] Improved "git add"
This fixes everybodys favourite complaint about "git add", namely that it
doesn't take directories.
We use "git-ls-files --others" to generate an arbitrary list of filenames,
and thus also automatically honor ignore-files while we're at it.
Side note: there's a lot of room for improvement here. In particular, if
we have a long list of filenames (importing a big archive), this will just
do a big stupid for-loop and add them one at a time. Maybe it should use
generate-list | xargs -0 git-update-idex --add --
instead.
Also, I think we should have a default ignore list if we don't find a
.git/info/exclude file. Ignoring "*.o" and ".*" by default would probably
be the right thing to do.
But I think this is a good first step.
Use the "-n" flag to just show the list of files to be added without
adding them.

in a file objects/info/http-alternates or
objects/info/alternates. Each line may be:
a relative path, starting with ../, to get from the objects directory
of the starting repository to the objects directory of the added
repository.
an absolute path of the objects directory of the added repository (on
the same server).
(only in http-alternates) a full URL of the objects directory of the
added repository.

Improve the safety check used in fetch.c
The recent safety check to trust only the commits we have made
things impossibly slow and turn out to waste a lot of memory.
This commit fixes it with the following improvements:
- mark already scanned objects and avoid rescanning the same
object again;
- free the tree entries when we have scanned the tree entries;
this is the same as b0d8923ec01fd91b75ab079034f89ced91500157
which reduced memory usage by rev-list;
- plug memory leak from the object_list dequeuing code;
- use the process_queue not just for fetching but for scanning,
to make things tail recursive to avoid deep recursion; the
deep recursion was especially prominent when we cloned a big
pack.
- avoid has_sha1_file() call when we already know we do not have
that object.

Do not fail after calling bisect_auto_next()
As a convenience measure, 'bisect bad' or 'bisect good' automatically
does 'bisect next' when it knows it can, but the result of that test
to see if it can was leaking through as the exit code from the whole

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

$ /usr/bin/time git-rev-list --objects v2.6.12..HEAD | wc -l

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.

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] rsh.c env and quoting cleanup, take 2
This patch does proper quoting, and uses "env" to be compatible with
tcsh. As a side benefit, I believe the code is a lot cleaner to read.
[jc: I am accepting this not because I necessarily agree with the
quoting approach taken by it, but because (1) the code is only used
by ssh-fetch/ssh-upload pair which I do not care much about (if you
have ssh account on the remote end you should be using git-send-pack
git-fetch-pack pair over ssh anyway), and (2) HPA is one of the more
important customers belonging to the Linux kernel community and I
want to help his workflow -- which includes not wasting his time by
asking him to switch to git-send-pack/git-fetch-pack pair, nor to use
a better shell ;-). I might not have taken this patch if it mucked
with git_connect in connect.c in its current form.]

[PATCH] git-http-fetch: Allow caching of retrieved objects by proxy servers
By default the curl library adds "Pragma: no-cache" header to all
requests, which disables caching by proxy servers. However, most
files in a GIT repository are immutable, and caching them is safe and
could be useful.
This patch removes the "Pragma: no-cache" header from requests for all
files except the pack list (objects/info/packs) and references
(refs/*), which are really mutable and should not be cached.

[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.
