When merging an early part of a branch, e.g. "git merge xyzzy~20", we were supposed to say "branch 'xyzzy' (early part)", but it incorrectly said "branch 'refs/heads/xy' (early part)" instead. The logic was supposed to first strip away "~20" part to make sure that what follows "~" is a non-zero posint, prefix it with "refs/heads/" and ask resolve_ref() if it is a ref. If it is, then we know xyzzy was a branch, and we can give the correct message. However, there were a few bugs. First of all, the logic to build this "true branch refname" did not count the characters correctly. At this point of the code, "len" is the number of trailing, non-name part of the given extended SHA-1 expression given by the user, i.e. number of bytes in "~20" in the above example. In addition, the message forgot to skip "refs/heads/" it prefixed from the output. 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/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.
