split up a repository

Hi all,

Ok, I *WAS* an SVN user, so forgive my ignorance. I have successfully migrated from SVN to git. However, I had only one repository under my SVN server, which is not a good approach with git.

Now I have one git repository, which I'd like to split up to several others. Does it possible with git? If it is, how?

How can I split up a single repo to several others? It would be nice to keep the history.

Thank you for your help in advance.

'git filter-branch' should do what you need. Have a read of this [1] recent discussion and the docs for filter-branch [2].

Heya,

Sounds like a job for.... subtree man! Avery (cc-ed) has written a program 'git subtree' that lets you split off subtrees from a git repository (and optionally merge them back later on). I reckon that's what you want, yes?

Yes, it seems!

Ok. Really newbie question here. Just before I start to mess up my repositories. I've cloned the git-subtree, and the install script would put the script into /usr/lib/git-core. Is there any way to install the script somewhere under /usr/local ?

Thanks,

I'll leave git subtree specific questions to Avery :).

The actual function of git-subtree is one single file. You can just copy it to wherever you like. Personally, I add the git-subtree source directory to my PATH from .bashrc... but I guess I'm special because I also change my version of git-subtree a lot :)

Make sure to run 'make test' first so you know it's working on your computer.

And I'll second Sverre's suggestion to *always* back up your repository before doing weird stuff (although git-subtree is designed to refuse to overwrite existing branches, and nobody has ever reported it damaging anything).

Have fun,

Avery

Does git-subtree support branching of the "main" repository and sub-trees in coordinated (one step) fashion?
