Suppose you're using git-svn to work with a certain SVN repository. Since you don't like 'git-svn fetch' to take forever, and you don't want to accidentally interrupt it and end up corrupting your repository, you set up a remote Git repository to mirror the SVN repository, which does its own 'git-svn fetch' on a cronjob; now you can 'git-fetch' from the Git mirror into your local repository, and still dcommit to SVN when you have changes to push. After you do this, though, git-svn will get very confused if you ever try to do 'git-svn fetch' in your local repository again, since its rev_map will differ from the branch's head, and it will be unable to fetch new commits from SVN because of the metadata conflict. But all the necessary metadata are there in the Git commit message; git-svn already knows how to rebuild rev_map files that get blown away, by using the metadata. This patch teaches git-svn do a partial rebuild of the rev_map to match the true state of the branch, if it ever is used to fetch again. This will only work for projects not using either noMetadata or useSvmProps configuration options; if you are using these options, git-svn will fall back to the previous behaviour.

//////////////////////////////////////////////////////////////// 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.
