I did the following:
1. mirror svn repository using svnsync
2. clone the mirror with git-svn --use-svnsync-props and some tweaking[*]
3. run git svn info in the clone
4. get error "Unable to determine upstream SVN information from working 
tree history"

git svn log and git svn rebase do not work either. git log does work.

I have git version 1.6.0.2 (from FreeBSD ports).
[*] About the tweaking - I manually massaged config file to get the 
branches I was interested in, so .git/config is this:
[core]
         repositoryformatversion = 0
         filemode = true
         bare = false
         logallrefupdates = true
[svn-remote "svn"]
         useSvnsyncProps = 1
         url = file:///system/devel/svn/base
         fetch = head:refs/remotes/trunk
         fetch = stable/6:refs/remotes/stable_6
         fetch = stable/7:refs/remotes/stable_7
         fetch = releng/6.3:refs/remotes/releng_6_3
         fetch = releng/6.4:refs/remotes/releng_6_4
         fetch = releng/7.0:refs/remotes/releng_7_0
         fetch = release/6.3.0:refs/remotes/release_6_3_0
         fetch = release/7.0.0:refs/remotes/release_7_0_0

This is .git/svn/.metadata:
; This file is used internally by git-svn
; You should not have to edit it
[svn-remote "svn"]
         reposRoot = file:///system/devel/svn/base
         uuid = ccf9f872-aa2e-dd11-9fc8-001c23d0bc1f
         svnsync-uuid = ccf9f872-aa2e-dd11-9fc8-001c23d0bc1f
         svnsync-url = svn://svn.freebsd.org/base

So you can see the original svn repository URL.

git log reports svn info like the following: git-svn-id: svn://svn.freebsd.org/base/stable/7@183898 ccf9f872-aa2e-dd11-9fc8-001c23d0bc1f

It seems that the problem is that the code in find_by_url() and/or read_all_remotes() subroutines (in git-svn.perl) are not aware of svnsync and do not realize an URL in logs and URL in svn-remote are different. BTW, I see that there is some special svm logic in read_all_remotes.

Thank you very much for any help in advance.

Anyone? I wonder if this is my local problem/misconfiguration or an issue with git-svn.

Same happens here, so it's a general issue ;)

I think I encountered that before and ended up experimenting with git-svn cloning from a svnsync source until I found the final config, with which I git-svn cloned directly from upstream, so that I had to wait only twice.

I hacked together an ugly patch that replaces svm support with snvsync support. This works for me, not sure if it will be useful in general.
