Commit0433ad1(clone: run check_everything_connected, 2013-03-25) added the same connectivity check to clone that we use for fetching. The intent was to provide enough safety checks that "git clone git://..." could be counted on to detect bit errors and other repo corruption, and not silently propagate them to the clone. For local clones, this turns out to be a bad idea, for two reasons: 1. Local clones use hard linking (or even shared object stores), and so complete far more quickly. The time spent on the connectivity check is therefore proportionally much more painful. 2. Local clones do not actually meet our safety guarantee anyway. The connectivity check makes sure we have all of the objects we claim to, but it does not check for bit errors. We will notice bit errors in commits and trees, but we do not load blob objects at all. Whereas over the pack transport, we actually recompute the sha1 of each object in the incoming packfile; bit errors change the sha1 of the object, which is then caught by the connectivity check. This patch drops the connectivity check in the local case. Note that we have to revert the changes from0433ad1to t5710, as we no longer notice the corruption during clone. We could go a step further and provide a "verify even local clones" option, but it is probably not worthwhile. You can already spell that as "cd foo.git && git fsck && git clone ." or as "git clone --no-local foo.git". Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

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.
