Problem with git-svn with limited SVN access

Hello,

I have a problem with a git-svn setup and although I spent most of yesterday googling for a solution but did not find any (see below for my failed attempts). I hope you guys here will be able to help me.

I have limited access to a SVN repository with a "standard" layout. By limited, I mean that I am allowed only to access the folders "trunk", "branches/XXX" and "branches/YYY".

*Attempt 1:*
 > git svn init svn://server/aaa/AAA -T trunk -b branches --username=UUU
Initialized empty Git repository in /home/.../.git/
Using higher level of URL: svn://server/aaa/AAA => svn://server/aaa
 > git svn fetch
Error from SVN, (220001): Item is not readable: Item is not readable

*Attempt 2:*
 > git svn init svn://server/aaa/AAA -T trunk -b branches --username=UUU 
--no-minimize-url
Initialized empty Git repository in /home/.../.git/
 > git svn fetch
W: Item is not readable: Item is not readable at 
/usr/libexec/git-core/git-svn line 1782

This may take a while on large repositories

At this point, I'm really lost and running out of ideas. If someone could help me with this, I would be very grateful.

Please forgive me if I posted to the wrong mailing-list but I could not find a specific git-svn list. If there is such thing, please point me in the right direction.

Thanks,

Antoine.

I think having several fetch specs should do the trick, although I cannot easily test with actual permissions.

You can start configuring the repo with

  git init
  git svn init svn://server/ -T trunk

to get an initial layout.  The .git/config will look like

  [svn-remote "svn"]
          url = svn://server/
          fetch = trunk:refs/remotes/trunk

The clue is that the config says 'fetch', not 'trunk'. Much like with git remotes, you can add more fetch specs along the lines of

          fetch = branches/XXX:refs/remotes/svn/XXX

or whatever layout you prefer.

Please tell us whether that works even in the face of restrictions on branches/ itself :-)

Thomas,

Thanks a lot for taking the time to look at my problem.

I did what you suggested. Now my .git/config looks like:

         fetch = trunk:refs/remotes/trunk
        fetch = branches/XXX:refs/remotes/svn/XXX
  and here is the result:
 > git svn fetch
W: Item is not readable: Item is not readable at 
/usr/libexec/git-core/git-svn line 1782

Error from SVN, (220001): Item is not readable: Item is not readable

Any other idea ? Or is there a way to get more debug info from git-svn. May be it would give us some insight on what it is trying to do and failing to.

Thanks,

Antoine.
