SVN to Clearcase Export

Question

I have a client who is rather insistent about using Clearcase. Are there any tools/scripts that would allow my team to work against an SVN repository (or really anything

Answer 1

I use Git directly within a ClearCase view.
Then I could git2svn back the content to SVN if I had a SVN repo to synchronize with.

Note: for a tool to work directly within a ClearCase view, I have to use a snapshot view, in order to write in files even if they are not checked out yet. Then for any activity I consider finished, I update the snapshot view which allows me to list all "hijacked" files. I check-out them, then check-in them.

The issue I would see with working with SVN in this case (ClearCase repo for the client) would be to:

• introduced another central repository (meaning to commit, you have to have access to your private central SVN repository, and, for "to-the-client commits", to have access to the central ClearCase VOB - Version Object Base, the "repository" in ClearCase lingo).
• introduced another branch modeling, where in SVN, it is a cheap copy within a directory, whereas in ClearCase, it is a metadata (branch) not represented as a directory. That means the physical tree of a SVN checkout might not match a snapshot view update in ClearCase, because some of the directories checked out by SVN will simply not exist in ClearCase.

At least, with Git, you have:

• private repository (you are not adding another central repository everyone should have access to)
• same branching model (at least when it comes to "not representing a branch by a directory")
