git-svn: add support for metadata in .git/config
Of course, we handle metadata migrations from previous versions and we have added unit tests. The new .git/config remotes resemble non-SVN remotes. Below is an example with comments: [svn-remote "git-svn"] ; like non-svn remotes, we have one URL per-remote url = http://foo.bar.org/svn ; 'fetch' keys are done in the same way as non-svn ; remotes, too. With the left-hand-side of the ':' ; being the remote (SVN) repository path relative to the ; above 'url' key; and the right-hand-side being a ; remote ref in git (refs/remotes/*). ; An empty left-hand-side means that it will fetch ; the entire contents of the 'url' key. ; old-style (migrated from previous versions of git-svn) ; are like this: fetch = :refs/remotes/git-svn ; this is created by a current version of git-svn ; using the multi-init command with an explicit ; url (specified above). This allows multi-init ; to reuse SVN::Ra connections. fetch = trunk:refs/remotes/trunk fetch = branches/a:refs/remotes/a fetch = branches/b:refs/remotes/b fetch = tags/0.1:refs/remotes/tags/0.1 fetch = tags/0.2:refs/remotes/tags/0.2 fetch = tags/0.3:refs/remotes/tags/0.3 [svn-remote "alt"] ; this is another old-style remote migrated over ; to the new config format url = http://foo.bar.org/alt fetch = :refs/remotes/alt Signed-off-by: Eric Wong <normalperson@yhbt.net>
