Shawn O. Pearce a5c1780a03 Don't repack existing objects in fast-import 
Some users of fast-import have been trying to use it to rewrite
commits and trees, an activity where the all of the relevant blobs
are already available from the existing packfiles.  In such a case
we don't want to repack a blob, even if the frontend application
has supplied us the raw data rather than a mark or a SHA-1 name.

I'm intentionally only checking the packfiles that existed when
fast-import started and am always ignoring all loose object files.

We ignore loose objects because fast-import tends to operate on a
very large number of objects in a very short timespan, and it is
usually creating new objects, not reusing existing ones.  In such
a situtation the majority of the objects will not be found in the
existing packfiles, nor will they be loose object files.  If the
frontend application really wants us to look at loose object files,
then they can just repack the repository before running fast-import.

	GIT - the stupid content tracker

////////////////////////////////////////////////////////////////

"git" can mean anything, depending on your mood.

 - random three-letter combination that is pronounceable, and not
   actually used by any common UNIX command.  The fact that it is a
   mispronunciation of "get" may or may not be relevant.
 - stupid. contemptible and despicable. simple. Take your pick from the
   dictionary of slang.
 - "global information tracker": you're in a good mood, and it actually
   works for you. Angels sing, and a light suddenly fills the room.
 - "goddamn idiotic truckload of sh*t": when it breaks

Git is a fast, scalable, distributed revision control system with an
unusually rich command set that provides both high-level operations
and full access to internals.

Git is an Open Source project covered by the GNU General Public License.
It was originally written by Linus Torvalds with help of a group of
hackers around the net. It is currently maintained by Junio C Hamano.

Please read the file INSTALL for installation instructions.
See Documentation/tutorial.txt to get started, then see
Documentation/everyday.txt for a useful minimum set of commands,
and "man git-commandname" for documentation of each command.
CVS users may also want to read Documentation/cvs-migration.txt.

Many Git online resources are accessible from http://git.or.cz/
including full documentation and Git related tools.

The user discussion and development of Git take place on the Git
mailing list -- everyone is welcome to post bug reports, feature
requests, comments and patches to git@vger.kernel.org. To subscribe
to the list, send an email with just "subscribe git" in the body to
majordomo@vger.kernel.org. The mailing list archives are available at
http://marc.theaimsgroup.com/?l=git and other archival sites.

The messages titled "A note from the maintainer", "What's in
git.git (stable)" and "What's cooking in git.git (topics)" and
the discussion following them on the mailing list give a good
reference for project status, development direction and
remaining tasks.
