Git Workflow Edit

A good workflow for new contributors to follow is listed below:
– Fork Gutenberg repository
– Clone forked repository
– Create a new branch
– Make code changes
– Commit code changes within the newly created branch
– Push branch to forked repository
– Submit Pull Request to Gutenberg repository

Ideally name your branches with prefixes and descriptions, like this: [type]/[change]. A good prefix would be:

  • add/ = add a new feature
  • try/ = experimental feature, “tentatively add”
  • update/ = update an existing feature

For example, add/gallery-block means you’re working on adding a new gallery block.

You can pick among all the tickets, or some of the ones labelled Good First Issue.

The workflow is documented in greater detail in the repository management document.

Keeping Your Branch Up To Date Keeping Your Branch Up To Date

When many different people are working on a project simultaneously, pull requests can go stale quickly. A “stale” pull request is one that is no longer up to date with the main line of development, and it needs to be updated before it can be merged into the project.

There are two ways to do this: merging and rebasing. In Gutenberg, the recommendation is to rebase. Rebasing means rewriting your changes as if they’re happening on top of the main line of development. This ensures the commit history is always clean and linear. Rebasing can be performed as many times as needed while you’re working on a pull request. Do share your work early on by opening a pull request and keeping your history rebase as you progress.

The main line of development is known as the master branch. If you have a pull-request branch that cannot be merged into master due to a conflict (this can happen for long-running pull requests), then in the course of rebasing you’ll have to manually resolve any conflicts in your local copy. Learn more in section Perform a rebase of How to Rebase a Pull Request.

Once you have resolved any conflicts locally you can update the pull request with git push --force-with-lease. Using the --force-with-lease parameter is important to guarantee that you don’t accidentally overwrite someone else’s work.

To sum it up, you need to fetch any new changes in the repository, rebase your branch on top of master, and push the result back to the repository. These are the corresponding commands:

git fetch
git rebase master
git push --force-with-lease your-branch-name

Keeping Your Fork Up To Date Keeping Your Fork Up To Date

Working on pull request starts with forking the Gutenberg repository, your separate working copy. Which can easily go out of sync as new pull requests are merged into the main repository. Here your working repository is a fork and the main Gutenberg repository is upstream. When working on new pull request you should always update your fork before you do git checkout -b my-new-branch to work on a feature or fix.

To sync your fork you need to fetch the upstream changes and merge them into your fork. These are the corresponding commands:

git fetch upstream
git checkout master
git merge upstream/master

This will update you local copy to update your fork on github push your changes

git push

The above commands will update your master branch from upstream. To update any other branch replace master with the respective branch name.
