The merge-one-file tool predates the invention of GIT_WORK_TREE. By the time GIT_WORK_TREE was invented, most people were using the merge-recursive strategy, which handles resolving internally. Therefore these features have had very little testing together. For the most part, merge-one-file just works with GIT_WORK_TREE; most of its heavy lifting is done by plumbing commands which do respect GIT_WORK_TREE properly. The one exception is a shell redirection which touches the worktree directly, writing results to the wrong place in the presence of a GIT_WORK_TREE variable. This means that merges won't even fail; they will silently produce incorrect results, throwing out the entire "theirs" side of files which need content-level merging! This patch makes merge-one-file chdir to the toplevel of the working tree (and exit if we don't have one). This most closely matches the assumption made by the original script (before separate work trees were invented), and matches what happens when the script is called as part of a merge strategy. While we're at it, we'll also error-check the call to cat. Merging a file in a subdirectory could in fact fail, as the redirection relies on the "checkout-index" call just prior to create leading directories. But we never noticed, since we ignored the error return from running cat. 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.
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/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. 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.
