[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] Return proper error valud from "parse_date()"
Right now we don't return any error value at all from parse_date(), and if
we can't parse it, we just silently leave the result buffer unchanged.
That's fine for the current user, which will always default to the current
date, but it's a crappy interface, and we might well be better off with an
error message rather than just the default date.
So let's change the thing to return a negative value if an error occurs,
and the length of the result otherwise (snprintf behaviour: if the buffer
is too small, it returns how big it _would_ have been).

[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.

Merge branch 'master' of .
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.

Archive-destroying "git repack -a -d" bug.
Using "git repack -a -d" can destroy your git archive if you use it
twice in succession, because the new pack can be called the same as
the old pack. Found by Linus.

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
thing, which was bad. Noticed by Anton Blanchard.

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.

[PATCH] Improve git-rev-list memory usage further
This avoids keeping tree entries around, and free's them as it traverses
the list. This avoids building up a huge memory footprint just for these
small but very common allocations.

11.65user 0.38system 0:12.65elapsed 95%CPU (0avgtext+0avgdata 0maxresident)k

0inputs+0outputs (0major+26718minor)pagefaults 0swaps
59124
Note how the minor fault numbers - which ends up being how many pages we
needed to map - go down from 42934 (167 MB) to 26718 (104 MB). That is:
Before:
42934 minor pagefaults
After:
26718 minor pagefaults
This is all in _addition_ to the previous fixes. It used to be
~48,000 pagefaults.
That's still a honking big memory footprint, but it's about half of what
it was just a day or two ago (and this is the object list for a pretty big
update - almost 60,000 objects. Smaller updates need less memory).
