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. http://logonex.eu/git/?p=svn.git;a=summary 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. Levente ``` ## Chris Packham, 2010-03-02 00:36 Subject: Re: split up a repository Message-ID: URL: https://gitlist.dev/e/a038bef51003011636n6dda8296k655b9d367cee9e91%40mail.gmail.com In-Reply-To: <20100302011226.76fda85d@gmail.com> ``` Hi, On Mon, Mar 1, 2010 at 4:12 PM, Kovacs, Levente wrote: > Hi all, > > > Ok, I *WAS* an SVN user, so forgive my ignorance.

Have a read of this [1] recent discussion and the docs for filter-branch [2].

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? -- Cheers, Sverre Rabbelier ``` ## Sverre Rabbelier, 2010-03-02 23:19 Subject: Re: split up a repository Message-ID: URL: https://gitlist.dev/e/fabb9a1e1003021519y7159a3dal3aa3a7514329fb9a%40mail.gmail.com In-Reply-To: <20100303002132.5df20326@gmail.com> ``` Heya, On Wed, Mar 3, 2010 at 00:21, Levente Kovacs wrote: > Ok.

I'll leave git subtree specific questions to Avery :). -- Cheers, Sverre Rabbelier ``` ## Levente Kovacs, 2010-03-02 23:21 Subject: Re: split up a repository Message-ID: <20100303002132.5df20326@gmail.com> URL: https://gitlist.dev/e/20100303002132.5df20326%40gmail.com In-Reply-To: ``` On Tue, 2 Mar 2010 11:40:41 +0100 Sverre Rabbelier wrote: > Sounds like a job for.... subtree man! 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 ?

Is there any way to install the script > somewhere under /usr/local ? 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 ``` ## Bill Lear, 2010-03-03 14:04 Subject: Re: split up a repository Message-ID: <19342.27760.544227.835077@blake.zopyra.com> URL: https://gitlist.dev/e/19342.27760.544227.835077%40blake.zopyra.com In-Reply-To: <32541b131003021740n32535fbbh802af418ea0898aa@mail.gmail.com> ``` On Tuesday, March 2, 2010 at 20:40:57 (-0500) Avery Pennarun writes: >On Tue, Mar 2, 2010 at 6:21 PM, Levente Kovacs wrote: >> On Tue, 2 Mar 2010 11:40:41 +0100 >> Ok.

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