The do_for_each_ref iteration function accepts a prefix and a trim, and checks for the prefix on each ref before passing in that ref; it also supports trimming off part of the ref before passing it. However, do_for_each_ref used trim as the length of the prefix to check, ignoring the actual length of the prefix. Switch to using prefixcmp, checking the entire length of the prefix string, to properly support a trim value different than the length of the prefix. Several callers passed a prefix of "refs/" to filter out everything outside of refs/, but a trim of 0 to avoid trimming off the "refs/"; the trim of 0 meant that the filter of "refs/" no longer applied. Change these callers to pass an empty prefix instead, to avoid changing the existing behavior. Various callers count on this lack of filtering, such as receive-pack which uses add_extra_ref to add alternates as refs named ".have"; adding filtering would break that, causing t5501-fetch-push-alternates.sh to fail. That lack of filtering doesn't currently have any other effect, since the loose ref functions can never supply refs outside of "refs/", and packed-refs will not normally include such refs unless manually edited.

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.
