# This workflow automates the process of upmerging changes from the current release branch to the edge branch. | |
# During the course of a release, the release branch is the default branch so that PRs can be immediately | |
# brought into the release without waiting for a new release. This workflow merges those changes into | |
# the edge branch so that edge can be used as the basis for the next release branch. | |
# | |
# This workflow assumes that it is being triggered from the current release branch, but it could be triggered from | |
# any branch, and it uses that branch as the source branch for merging into the edge branch. | |
# The workflow is triggered manually via the workflow_dispatch event. | |
# | |
# The workflow performs the following steps: | |
# 1. Checks out the edge branch. | |
# 2. Configures git with a user name and email. | |
# 3. Creates a new branch from edge. | |
# 4. Merges changes from the branch executing the workflow into the edge branch created in the previous step. | |
# 5. Pushes the new branch if there are changes. | |
# 6. Creates a pull request to merge the new branch into edge. | |
# Example: | |
# The current release branch is v0.36. We are creating the new release for v0.37. | |
# The release person manually triggers this workflow from branch v0.36. The workflow runs, which does the following | |
# 1. A new branch is created named upmerge/2024-07-31-98b9. The source branch is edge. | |
# 2. Changes from branch v0.36 are merged into branch upmerge/2024-07-31-98b9. | |
# 3. A PR is created from branch upmerge/2024-07-31-98b9 --> edge. The workflow finishes and reports success. | |
