I'm working on preparing Git SVN mirrors.

I had tested my procedure on a small project and it was working fine.

On a large project it is failing. Here is what I have done:

I have cloned the repository using:

    $ git svn clone --prefix=svn/ file:///path/repo \
	--revision=15314:HEAD --trunk=trunk/project \
	--tags=tags/project --branches=branches/project \
	--branches="branches/global/*/project" project

Not simple, ok but working :)

Now I have converted the file:// to svn+ssh:// using:

    $ git gc

    $ git filter-branch --msg-filter \
     'sed "s,git-svn-id: file:///path/repo,git-svn-id: 
svn+ssh://server/repo,g"' \
     $(cat .git/packed-refs | awk '// {print $2}' | grep -v 'pack-refs')

    $ rm -fr .git/svn

I have edited .git/config to change the url string too.

Up to there, no problem. But when trying to rebase and reconstruct all 
rev_map files with:

    $ git svn rebase

I get the following lines again and again:

Rebuilding 
.git/svn/svn/trunk/.rev_map.f8352e7e-cb20-0410-8ce7-b5d9e71c585c ...
Done rebuilding 
.git/svn/svn/trunk/.rev_map.f8352e7e-cb20-0410-8ce7-b5d9e71c585c
Rebuilding 
.git/svn/svn/trunk/.rev_map.f8352e7e-cb20-0410-8ce7-b5d9e71c585c ...
Done rebuilding 
.git/svn/svn/trunk/.rev_map.f8352e7e-cb20-0410-8ce7-b5d9e71c585c

...

The file 
.git/svn/svn/trunk/.rev_map.f8352e7e-cb20-0410-8ce7-b5d9e71c585c is in 
fact not created.

What could be wrong?

How should I proceed to debug this?

Any help appreciated.

Last note I've tried all this with Git 1.6.4 and 1.6.5.

Thanks,
Pascal.

I'm not sure about the actual bug you're experiencing, but you could
have done this more simply using the --rewrite-root option to git-svn.
 It might still save you time to just do that from scratch.

If you really want to debug it, you might want to run it through
'strace' and see if it's having any trouble creating those files.

Have fun,

Avery

Another thing: if your file:// repository was copied from the original
location using SVN::Mirror or svnsync, then git-svn is capable of
reading the breadcrumbs left by those tools with a switch and rewriting
the git-svn-id: lines accordingly.
