![]() When 'git fetch' is supplied a single argument, it tries to match it against a configured remote and then fetch the refs specified by the named remote's fetchspec. Additionally, or alternatively, if the current branch has a merge ref configured, and if the name of the remote supplied to fetch matches the one in the branch's configuration, then git also adds the merge ref to the list of refs to update. If the argument to fetch does not specify a named remote, or if the name supplied does not match the remote configured for the current branch, then the current branch's merge configuration should not be considered. git currently mishandles the case when the argument to fetch specifies a GIT URL(i.e. not a named remote) and the current branch has a configured merge ref. In this case, fetch should ignore the branch's merge ref and attempt to fetch from the remote repository's HEAD branch. But, since fetch only checks _whether_ the current branch has a merge ref configured, and does _not_ check whether the branch's configured remote matches the command line argument (until later), it will mistakenly enter the wrong branch of an 'if' statement and will not fall back to fetch the HEAD branch. The fetch ends up doing nothing and returns with a successful zero status. Fix this by comparing the remote repository's name to the branch's remote name, in addition to whether it has a configured merge ref, sooner, so that fetch can correctly decide whether the branch's configuration is interesting or not, and fall back to fetching from the remote's HEAD branch when appropriate. This fixes the test in t5510. Signed-off-by: Brandon Casey <casey@nrlssc.navy.mil> 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.
