[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).

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.

However, nothing else really needs it, and it's quite expensive for

So, exactly like the commit buffer save thing, add a global flag to

Calculating the total object difference between two git revisions is still

[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.

note how the minor faults have decreased from 3714 pages to 2433 pages.
That's all due to the fewer anonymous pages allocated to hold the comment

[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/

    /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.
