13 September Remote branches in git

I have been using git for a while now, and I believe I have the the basic workflow under control. Committing, reverting, using local branches for major refactoring work: been there, done that! ;) However, I recently got some collaborators on my github-projects, I had to start working with other remote repositories and branches.

I found this blog post, which was really helpful. I am sharing some others things that helped me in the last couple of weeks. Hopefully, this saves other people some time Googling. If you know a better ways to accomplish these tasks, please let me know!

Things to remember about remote branches

Because I had some troubles discovering how to properly work with remote repositories, I am sharing what I found. The most important things to remember:

  • Your local branches are not really connected to the remote branches. It is therefore possible to mix up branches, but this is usually not what you want :-)
  • Never forget to switch to the correct local branch (using git checkout local-branch.
  • The names of the local and remote do not need to match.
  • Before you can push changes from a local branch to a remote branch, all the commits of the remote branch have to be included in your local branch. This can be done using by executing git pull remote-name remote-branch in your local branch.

Checking out a newly created branch in a remote repository

Bart is implementing Merb log parsing for request-log-analyzer. He has put his progress in a separate branch of the github project. My local repository does not yet include this branch, but I want to check it out. Note that I am using a different name than the branch name on the github project.

$ git branch merb origin/generic_base
$ git checkout merb

When the new functionality is finished, the following commands will merge the changes in the merb branch to the master branch.

  # goto my local master branch and merge the merb-branch
$ git checkout master
$ git merge merb
 
  # push the changes to the master branch on github
$ git push origin master

Merging back a fork

Wes Hays is helping me out on the scoped_search plugin. He implemented OR in the query language in his own fork. I wanted to merge his changes back to master branch:

  # add a reference to the remote repository
$ git remote add gbdev git://github.com/gbdev/scoped_search.git
 
  # create a local branch for the fork to follow a remote branch
$ git branch gbdev-fork gbdev/master
$ git checkout gbdev-fork

Now, my local gbdev-fork branch contains Wes’s code. Because Wes’s repository was forked from my repository, git will know that most of the history of my master branch and gbdev-fork branch is the same.

After some testing, I was ready to include his changes by merging the gbdev-fork branch into my local master branch:

  # go back to my master branch, and merge the changes
$ git checkout master
$ git merge gbdev-fork
  # push the changes to the master branch at hithub
$ git push origin master

Pushing tags to a remote repository

You can create tags locally, but you probably want to send them to the remot repository as well:

  # create a local tag "tagname" with the given message.
$ git tag -a "tagname" -m "message" 
  # send your tags to the remote repository "origin"
$ git push origin --tags
