Hi *,
I've made a script to push to a bundle that tries to behave as the
normal push.
It has some limitations, but for the normal cases it works fine.
The basic idea is:
- Easily create bundles with the current branch.
- Be able to push to defined bundles in remote.<remote>.url
- Only add new objects by default (do not lose objects)
- Reuse existing bundles (keep the basis and the branches)
- Check that the branches fast-forward
- Keep the pushed branches in refs/remotes/<remote>/*
But it also has some limitations:
- Do not allow refspec (git-bundle do not support them), only branch/tags names.
- Push all branches or none (consequence of the above)
- ...
Hope this helps,
Santi
The scripts follows, but also attatched.
