The only differences in behavior should be: - git checkout -m with non-trivial merging won't print out merge-recursive messages (see the change in t7201-co.sh) - git checkout -- paths... will give a sensible error message if HEAD is invalid as a commit. - some intermediate states which were written to disk in the shell version (in particular, index states) are only kept in memory in this version, and therefore these can no longer be revealed by later write operations becoming impossible. - when we change branches, we discard MERGE_MSG, SQUASH_MSG, and rr-cache/MERGE_RR, like reset always has. I'm not 100% sure I got the merge recursive setup exactly right; the base for a non-trivial merge in the shell code doesn't seem theoretically justified to me, but I tried to match it anyway, and the tests all pass this way. Other than these items, the results should be identical to the shell version, so far as I can 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. 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.
