Merging two remote repositories in Git

Question

I want to merge two remote repositories in Git.

One is mainstream repository, which I do not have write permission. I want to track its master branch.

The other is maintained by us, I have full rights on it.

I want to track the mainstream code. At the same time, our modification would be recorded in my remote repository.

How do I do this?

Answer 1

I would recommend:

• cloning yourRemoteRepo (that way, you can easily pull/push from that repo)

• adding mainstreamRepo as a remote and fetch its branch, then track the one which interest you

  git clone git://yourRemoteRepo
  git remote add mainStreamRepo http://mainStreamRepo
  git fetch mainStreamRepo
  git checkout -b mainStreamMaster mainStreamRepo/master
  git checkout master
  

From there, you can

• merge mainStreamMaster to your master,
• or rebase your master on top of mainStreamMaster (in order to integrate the full history of mainStreamMaster into your master branch)
• then make some evolutions to master (or to a topic-specific branch) that you can push to yourRemoteRepo.
