To protect the Git service, Heroku imposes certain limits on Git repository use and content size.Users are limited to a rolling window of 75 Git requests per hour, per user, per app.$ git fetch upstream # Grab the upstream remote's branches remote: Counting objects: 75, done. remote: Total 62 (delta 27), reused 44 (delta 9) Unpacking objects: 100% (62/62), done.From https://github.com/otheruser/repo * [new branch] master -$ git checkout master # Check out our local master branch Switched to branch 'master' $ git merge upstream/master # Merge upstream's master into our own Updating a422352..5fdff0f Fast-forward README | 9 ------- | 7 2 files changed, 7 insertions( ), 9 deletions(-) delete mode 100644 README create mode 100644 This updates my local fork, but my fork on still says "43 commits behind".And when I hit "Click to create a pull request" it created a PR on the SOURCE repo. Still works (Marchi 2015), all though the "Switching the base" link is no longer there.You have to change the "Base" drop down's so both point to your fork and then you'll get a prompt to "Compare across repos", which will take you to where you want.$ git remote -v # List the current remotes origin https://github.com/user/(fetch) origin https://github.com/user/(push) $ git remote add upstream https://github.com/otheruser/# Set a new remote $ git remote -v # Verify new remote origin https://github.com/user/(fetch) origin https://github.com/user/(push) upstream https://github.com/otheruser/(fetch) upstream https://github.com/otheruser/(push) There are two steps required to sync your repository with the upstream: first you must fetch from the remote, then you must merge the desired branch into your local branch.I recently forked a project and applied several fixes.I then created a pull request which was then accepted. Do I need to delete and re-create my fork when I have further changes to contribute? # Add the remote, call it "upstream": git remote add upstream https://github.com/whoever/# Fetch all the branches of that remote into remote-tracking branches, # such as upstream/master: git fetch upstream # Make sure that you're on your master branch: git checkout master # Rewrite your master branch so that any commits of yours that # aren't already in upstream/master are replayed on top of that # other branch: git rebase upstream/master As your fork only exists on github, and github does not have tools for doing merges through the web interface, then the right answer is to do the upstream merge locally and push the changes back to your fork.
Buildpacks can optionally cache content for re-use between builds.A few days later another change was made by another contributor. A quick note that rather than having to rebase your own master branch to ensure you are starting with clean state, you should probably work on a separate branch and make a pull request from that.This keeps your master clean for any future merges and it stops you from having to rewrite history with commits every time you try to get the updates from the upstream?Fetching from the remote repository will bring in its branches and their respective commits.These are stored in your local repository under special branches.
