The code paths in fsck for packed and loose objects are
quite different, and it is not immediately obvious that the
packed case behaves well. In particular:
1. The fsck_loose() function always returns "0" to tell the
iterator to keep checking more objects. Whereas
fsck_obj_buffer() (which handles packed objects)
returns -1. This is OK, because the callback machinery
for verify_pack() does not stop when it sees a non-zero
return.
2. The fsck_loose() function sets the ERROR_OBJECT bit
when fsck_obj() fails, whereas fsck_obj_buffer() sets it
only when it sees a corrupt object. This turns out not
to matter. We don't actually do anything with this bit
except exit the program with a non-zero code, and that
is handled already by the non-zero return from the
function.
So there are no bugs here, but it was certainly confusing to
me. And we do not test either of the properties in t1450
(neither that a non-corruption error will caused a non-zero
exit for a packed object, nor that we keep going after
seeing the first error). Let's test both of those
conditions, so that we'll notice if any of those assumptions
becomes invalid.

Git - fast, scalable, distributed revision control system
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.
Many Git online resources are accessible from http://git-scm.com/ including full documentation and Git related tools.
See Documentation/gittutorial.txt to get started, then see
Documentation/giteveryday.txt for a useful minimum set of commands, and
Documentation/git-.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).
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.
The name "git" was given by Linus Torvalds when he wrote the very first version. He described the tool as "the stupid content tracker" and the name as (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
