Sometimes when working with a large repository it can be useful to try out a merge and only check out conflicting files to disk (for example as a speed optimization on a server). Until v1.7.7-rc1~28^2~20 (merge-recursive: When we detect we can skip an update, actually skip it, 2011-08-11), it was possible to do so with the following idiom: # Prepare a temporary index and empty work tree. GIT_INDEX_FILE="$PWD/tmp-$$-index" && export GIT_INDEX_FILE && GIT_WORK_TREE="$PWD/tmp-$$-work" && export GIT_WORK_TREE && mkdir "$GIT_WORK_TREE" && # Convince the index that our side is on disk. git read-tree -i -m $ours && git update-index --ignore-missing --refresh && # Merge their side into our side. bases=$(git merge-base --all $ours $theirs) && git merge-recursive $bases -- $ours $theirs && tree=$(git write-tree) Nowadays, that still works and the exit status is the same, but merge-recursive produces a diagnostic if "our" side renamed a file: error: addinfo_cache failed for path 'dst' Add a test to document this regression.

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.
