Fetch from remote A, push to remote B

Fetch from remote A, push to remote B

[Martin Langhoff]

Is there an easy way to get a "passthrough" repo setup so I can say on a cronjob

  git-fetch remoteA
  git-push ssh+git://host/path/to/repoB.git remotes/remoteA/<all>

The 2 repositories cannot talk to each other directly.

cheers,

After mucking about with stuff like...

find .git/refs/remotes/origin -type f -printf '%P\0' | xargs -0
-IHEADNAME git-push
git+ssh://git.catalyst.net.nz/var/git/moodle-r2-testing.git
origin/HEADNAME:HEADNAME

I figured out that a bare repo did the trick

  # set things up
  git-clone --bare git+ssh://host-a/bla.git bla-transfer.git

  # on cron do
  GIT_DIR=bla-transfer.git git-fetch git+ssh://host-a/bla.git
  GIT_DIR=bla-transfer.git git-push --all git+ssh://host-b/bla.git

cheers!

Actually -- this doesn't quite work - the fetch grabs the new objects
properly but doesn't update the local heads on a bare repo.

Should this work?

GIT_DIR=bla-transfer.git git-fetch git+ssh://host-a/bla.git
+refs/heads/*:refs/heads/*

Earlier discussions about mirroring tools (and Pasky's git-mirror)
finished with this being the recommended technique. Only - it does on
me with

* refusing to create funny ref 'heads/*' locally

cheers,

To finish off the soliloquy... effective mirroring with git

  git-clone --bare git://host/repo.git mirror.git
  git --git-dir=mirror.git config remote.origin.url git://host/repo.git
  git --git-dir=mirror.git config remote.origin.fetch
'+refs/heads/*:refs/heads/*'

  and now, on cron...
  git --git-dir=mirror.git fetch -u
  git --git-dir=mirror.git remote prune origin

(Thanks to Shawn Pearce for helping me figure out why it wasn't working for me!)

cheers
