When trying to find a .mailmap file, we will always look for it in the current directory. This makes sense in a repository with a working tree, since we'd always go to the toplevel directory at startup. But for a bare repository, it can be confusing. With an option like --git-dir (or $GIT_DIR in the environment), we don't chdir at all, and we'd read .mailmap from whatever directory you happened to be in before starting Git. (Note that --git-dir without specifying a working tree historically means "the current directory is the root of the working tree", but most bare repositories will have core.bare set these days, meaning they will realize there is no working tree at all). The documentation for gitmailmap(5) says: If the file `.mailmap` exists at the toplevel of the repository[...] which likewise reinforces the notion that we are looking in the working tree. This patch prevents us from looking for such a file when we're in a bare repository. This does break something that used to work: cd bare.git git cat-file blob HEAD:.mailmap >.mailmap git shortlog But that was never advertised in the documentation. And these days we have mailmap.blob (which defaults to HEAD:.mailmap) to do the same thing in a much cleaner way. However, there's one more interesting case: we might not have a repository at all! The git-shortlog command can be run with git-log output fed on its stdin, and it will apply the mailmap. In that case, it probably does make sense to read .mailmap from the current directory. This patch will continue to do so. That leads to one even weirder case: if you run git-shortlog to process stdin, the input _could_ be from a different repository entirely. Should we respect the in-tree .mailmap then? Probably yes. Whatever the source of the input, if shortlog is running in a repository, the documentation claims that we'd read the .mailmap from its top-level (and of course it's reasonably likely that it _is_ from the same repo, and the user just preferred to run git-log and git-shortlog separately for whatever reason). The included test covers these cases, and we now document the "no repo" case explicitly. We also add a test that confirms we find a top-level ".mailmap" even when we start in a subdirectory of the working tree. This worked both before and after this commit, but we never tested it explicitly (it works because we always chdir to the top-level of the working tree if there is one).

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 https://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-<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).
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 https://lore.kernel.org/git/, http://marc.info/?l=git and other archival sites.
Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.
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
