That person may be tremendously happy…that is, until, you try to “git svn fetch” to get new revisions and branched and what have you, and you get an error message like this:

Last fetched revision of (some branch or tag) was r3421, but we are about to fetch: r3421!

In an attempt to fix it, you may find this blog post, saying to remove the .ref files from your svn directory, which also proves fruitless.

The fix: modify the .git/svn/.metadata file so that the branches-maxRev and tags-maxRev equals the latest commit revision in svn.  So it should look like this after you are done:

; This file is used internally by git-svn
; You should not have to edit it
[svn-remote "svn"]
 reposRoot = (svn server name)
 uuid = c08781d2-f03e-0410-8c7c-e884ea3e41f3
 branches-maxRev = 17224
 tags-maxRev = 17224

Where 17224 was our latest revision.

I got the idea from git-svn’s webpage, where it states:

If the subset of branches or tags is changed after fetching, then .git/svn/.metadata must be manually edited to remove (or reset) branches-maxRev and/or tags-maxRev as appropriate.

I must caveat this with the fact that I have no idea why this works. Git svn is still black magic to me, and making this work is akin to me throwing muskrat bones onto a flaming pyre, and drawing conclusions from the charred remains.  Maybe someone with more git knowledge could drop it off here?

I also set up a google code project here for it.  Please let me know if you have any features or feedback on it.

Thanks!
