Nguyễn Thái Ngọc Duy 125f81461d gc --aggressive: make --depth configurable 
When 1c192f3 (gc --aggressive: make it really aggressive - 2007-12-06)
made --depth=250 the default value, it didn't really explain the
reason behind, especially the pros and cons of --depth=250.

An old mail from Linus below explains it at length. Long story short,
--depth=250 is a disk saver and a performance killer. Not everybody
agrees on that aggressiveness. Let the user configure it.

    From: Linus Torvalds <torvalds@linux-foundation.org>

    Heh. And this is why you want to do it exactly *once*, and then just
    export the end result for others ;)

    But yeah, especially if you allow longer delta chains, the end result can
    be much smaller (and what makes the one-time repack more expensive is the
    window size, not the delta chain - you could make the delta chains longer
    with no cost overhead at packing time)

    HOWEVER.

    The longer delta chains do make it potentially much more expensive to then
    use old history. So there's a trade-off. And quite frankly, a delta depth
    of 250 is likely going to cause overflows in the delta cache (which is
    only 256 entries in size *and* it's a hash, so it's going to start having
    hash conflicts long before hitting the 250 depth limit).

    So when I said "--depth=250 --window=250", I chose those numbers more as
    an example of extremely aggressive packing, and I'm not at all sure that
    the end result is necessarily wonderfully usable. It's going to save disk
    space (and network bandwidth - the delta's will be re-used for the network
    protocol too!), but there are definitely downsides too, and using long
    delta chains may simply not be worth it in practice.

    (And some of it might just want to have git tuning, ie if people think
    that long deltas are worth it, we could easily just expand on the delta
    hash, at the cost of some more memory used!)

    That said, the good news is that working with *new* history will not be
    affected negatively, and if you want to be _really_ sneaky, there are ways
    to say "create a pack that contains the history up to a version one year
    ago, and be very aggressive about those old versions that we still want to
    have around, but do a separate pack for newer stuff using less aggressive
    parameters"

    So this is something that can be tweaked, although we don't really have
    any really nice interfaces for stuff like that (ie the git delta cache
    size is hardcoded in the sources and cannot be set in the config file, and
    the "pack old history more aggressively" involves some manual scripting
    and knowing how "git pack-objects" works rather than any nice simple
    command line switch).

    So the thing to take away from this is:
     - git is certainly flexible as hell
     - .. but to get the full power you may need to tweak things
     - .. happily you really only need to have one person to do the tweaking,
       and the tweaked end results will be available to others that do not
       need to know/care.

    And whether the difference between 320MB and 500MB is worth any really
    involved tweaking (considering the potential downsides), I really don't
    know. Only testing will tell.

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

	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 version 2 (some parts of it are under different licenses,
compatible with the GPLv2). It was originally written by Linus
Torvalds with help of a group of hackers around the net.

Please read the file INSTALL for installation instructions.

See Documentation/gittutorial.txt to get started, then see
Documentation/everyday.txt for a useful minimum set of commands, and
Documentation/git-commandname.txt for documentation of each command.
If git has been correctly installed, then the tutorial can also be
read with "man gittutorial" or "git help tutorial", and the
documentation of each command with "man git-commandname" or "git help
commandname".

CVS users may also want to read Documentation/gitcvs-migration.txt
("man gitcvs-migration" or "git help cvs-migration" if git is
installed).

Many Git online resources are accessible from http://git-scm.com/
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 (read
Documentation/SubmittingPatches for instructions on patch submission).
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://news.gmane.org/gmane.comp.version-control.git/,
http://marc.info/?l=git and other archival sites.

The maintainer frequently sends the "What's cooking" reports that
list the current status of various development topics to the mailing
list.  The discussion following them give a good reference for
project status, development direction and remaining tasks.
