Keeping your pull request in sync with the base branch

About keeping your pull request in sync

Before merging your pull requests, other changes may get merged into the base branch causing your pull request's head branch to be out of sync. Updating your pull request with the latest changes from the base branch can help catch problems prior to merging.

You can update a pull request's head branch from the command line or the pull request page. The Update branch button is displayed when all of these are true:

• There are no merge conflicts between the pull request branch and the base branch.
• The pull request branch is not up to date with the base branch.
• The base branch requires branches to be up to date before merging.

For more information, see "Require status checks before merging."

If there are changes to the base branch that cause merge conflicts in your pull request branch, you will not be able to update the branch until all conflicts are resolved. For more information, see "About merge conflicts."

Updating your branch from the pull request page performs a traditional merge. The resulting merge commit merges the base branch into the head branch of the pull request.

Updating your pull request branch

1. リポジトリ名の下にある [pull request] をクリックします。

2. In the "Pull requests" list, click the pull request you'd like to update.

3. In the merge section near the bottom of the page, click Update branch to perform a traditional merge.
