If a project has to have multiple git repos (e.g. Bitbucket and Github) then it's better that they remain in sync.
Usually this would involve pushing each branch to each repo in turn, but actually Git allows pushing to multiple repos in one go.
If in doubt about what git is doing when you run these commands, just
edit .git/config (git-config(1)) and see what it's put there.
Suppose your git remotes are set up like this:
git remote add github [email protected]:muccg/my-project.git git remote add bb [email protected]:ccgmurdoch/my-project.git
The origin remote probably points to one of these URLs.
To set up the push URLs do this:
git remote set-url --add --push origin [email protected]:muccg/my-project.git git remote set-url --add --push origin [email protected]:ccgmurdoch/my-project.git
It will change the remote.origin.pushurl config entry. Now pushes
will send to both of these destinations, rather than the fetch URL.
Check it out by running:
git remote show origin
A branch can push and pull from separate remotes. This might be useful
in rare circumstances such as maintaining a fork with customizations
to the upstream repo. If your branch follows github by default:
git branch --set-upstream-to=github next_release
(That command changed branch.next_release.remote.)
Then git allows branches to have multiple branch.<name>.pushRemote
entries. You must edit the .git/config file to set them.
You can't pull from multiple remotes at once, but you can fetch from all of them:
git fetch --all
Note that fetching won't update your current branch (that's why
git-pull exists), so you have to merge -- fast-forward or
otherwise.
For example, this will octopus merge the branches if the remotes got out of sync:
git merge github/next_release bb/next_release
