Overview
For terminology, see upstream/base and head repositories.
The typical GitHub forked repository topology is similar to:
Initial Setup
Fork
Go to GitHub UI and click on the "Fork" button at the top of the page. Use your own "personal" organization ("ovidiu") to fork into.
Clone
Clone as usual:
git clone git@github.com:ovidiu/blue.git
Establish Relationships
Setup the "upstream" Repository
Establish a direct relationship between the local clone and the "upstream" repository. This will allow to pull the latest version of branches directly from the upstream repository.
git remote add upstream git@github.com:blue/blue.git
.git/config will contain:
[remote "upstream"]
url = git@github.com:blue/blue.git
fetch = +refs/heads/*:refs/remotes/upstream/*
To list currently configured remotes, use:
git remote -v
This configuration will allow us to fetch directly from "upstream"
git fetch upstream
Configure the "main" Branch to Update From Upstream
git fetch upstream
git branch --set-upstream-to=upstream/main main
This will configure the local "main" branch to track upstream's "main" branch. The .git/config will look like:
[branch "main"]
remote = upstream
merge = refs/heads/main
git pull will automatically apply upstream's "main" branch changes to the local main.
To fetch PRs, you can optionally add:
fetch = +refs/pull/*/head:refs/remotes/upstream/pr/*
PR Cycle
Send a PR
Push the commit in the head repository.
PR will show up both in the origin and upstream repository UI.
From the Origin Repository UI
Click "Compare & pull request"
The UI will give you the default choice to send the PR against the base repository while "Create pull request". Use it.
From the Upstream Repository UI
TODO
Merge the PR
Upon approval, merge the PR in upstream. The branch in the head repository will remain, and it has to be deleted explicitly as described in Clean Up the Branch section below.
Sync the Repositories after the PR Merge
There are two repositories to be synced: the origin repository and its local clone.
The local clone can be just simply git pull because its main branch is tracking the upstream repository.
The origin repository's main branch can be synced from the GitHub UI: In the origin repository's UI, use "Fetch upstream" button, then "Fetch and Merge".
Clean Up the Branch
From the local clone:
git branch -D of/branch-that-has-just-been-merged
git push origin :of/branch-that-has-just-been-merged
Additional tidying up:
git remote prune origin
git remote prune upstream
