git-svn or git problem...

David Kastrup· May 21, 2007, 07:54 UTC · lore

Hi,

I have used git-svn for checking out the trunk of a large Subversion archive. The .git subdirectory now sits in the /rep/texlive/trunk directory.

But I actually would now want to have the branches (which are pretty small in comparison) available in git as well, without checking the whole trunk out again.

Is there a way to move the .git tracking one directory level upwards and get the branches into it as well, without checking out the trunk again (the trunk is several Gigabytes of size)?

If you're using a 1.5.1 or later version of git-svn, you can do so pretty easily by editing your .git/config:

If you already have something like:

[svn-remote "svn"]
	# url here is the repository root, and 'mpc/trunk' in fetch
	# is the relative path within the repository
        url = https://svn.musicpd.org
        fetch = mpc/trunk:refs/remotes/git-svn

You can just add the following lines to the config in the above section:

        branches = mpc/branches/*:refs/remotes/*
        tags = mpc/tags/*:refs/remotes/tags/*

If you have something like:

[svn-remote "svn"]
	# url here is the full path of what you're tracking,
        url = https://svn.musicpd.org/mpc/trunk
        fetch = :refs/remotes/git-svn

Change it to something like in the first example (assuming you have read permissions to the repository root).

If recompiling SVN is feasible for you and the branches (as a fresh checkout) are as big as trunk, I highly recommend the do_switch patch for SVN which lets you transfer only a delta between the branch/tag point of trunk:

In case you're using Debian x86-32, I've uploaded .deb packages (with full, Debian sources) here:

http://git-svn.bogomips.org/svn/

The patch by itself is available here:
