git-svn mirror in bare repo

git-svn mirror in bare repo

[Enrico Weigelt]

Hi folks,

is it possible to use git-svn w/ an bare repository (eg. using
an temporary workdir when necessary or directly creating tree
and commit objects w/o going through workdir at all) ?

I'm running a dozen of mirrors (also from cvs), some from fairly
large and I'd like to get rid of the working copies.

No.

Your only option is a different conversion tool. GSoC resulted in a lot
of code in this direction, but I'm not sure it can do without a workdir.
It is based on svndump

hmm, can it work with an external workdir ?

I guess that requires access to the raw repository (on the server),
not just unprivileged svn client access, right ?

You can have the workdir anywhere you like by using the core.worktree
setting. So, if you mind the size requirements you can put it onto some
fast tempdir (tmpfs, say). In fact, if all you do is "git svn fetch"
then git svn may not even notice a missing worktree (would have to try).
"git svn rebase" does need a worktree.

In fact, Ram's GSoC project started off with svnrdump which is now part
of the subversion code base (i.e. in their trunk). It is basically
"svndump remote", i.e. a client outputting svn dump format.

When I have a large repository with git-svn that I only occasionally
want to use the working copy of it, here is what I do:

1) git svn clone the SVN repository normally
2) Create an "empty" branch with no files ("git checkout --orphan")

When I want to update SVN, I do:

  git checkout trunk
  git svn rebase
  git checkout empty

When I want to push something to SVN I do:

  git checkout trunk
  git svn dcommit
  git checkout empty

This makes it work sort of like a bare repository, but it still works
with git-svn. I use this when I have a bunch of SVN repositories I need
to be able to work with quickly at any time, but I don't want to waste
the disk space having all of their working copies checked out
simultaneously.
