Hi Daniele,
I think you're stuck. Someone who knows git-svn better than I might be able to figure out a solution (I haven't played with using wildcards in the middle of branches refspecs), but as far as I can tell git-svn can't support your repository's structure.
The fundamental problem is that the BRANCHES/ hierarchy isn't consistent. git-svn expects the directories under a 'branches' path to be branch names. In your case, you can't specify a configuration that covers your whole repository.
This:
branches = <url>/BRANCHES/DEV/*:refs/remotes/svn/dev/* branches = <url>/BRANCHES/BUILDS/*:refs/remotes/svn/builds/*
will let you track the stuff under BRANCHES/DEV and BRANCHES/BUILDS, but won't let you see the V*.* branches.
This:
branches = <url>/BRANCHES/*:refs/remotes/svn/*
will let you see the V*.* branches, but will get confused over the DEV and BUILDS stuff (because it's expecting the layout to be DEV/root and BUILDS/root).
So I think git-svn would need to be modified to support your situation.
One possible approach is to make git-svn smart about what it considers a branch's name. In theory, what you'd like is to just specify
branches = <url>/BRANCHES/*:refs/remotes/svn/*
and have git-svn properly identify all the branches:
V1.0 V1.1 V1.2 DEV/FEATURE1 DEV/FEATURE2 DEV/FEATURE3 BUILDS/BUILD1 BUILDS/BUILD2 BUILDS/BUILD3
To do this, git-svn could track the current 'trunk' directory structure (just the top-level contents of the root should suffice). Then when it detects a new path under BRANCHES it could search through that path until it finds the same 'trunk' directory structure, and then use the path as the full branch name.
For example, say a repository's trunk has 3 directories and a file: trunk/ foo/... bar/... baz/... readme.txt When a commit creates a new branch: branches/some/path/ foo/... bar/... baz/... readme.txt git-svn sees that the commit is to a new path under branches/ and looks through branches/some/ and branches/some/path/ to find the trunk's contents, deciding in this case that 'some/path' is the branch's name.
Anyway, this is just an idea of how things might work. There are probably some corner-cases that could make this a bit tricky to implement...
