migrate-pullreqs is a utility that changes the base branch of a
repository's pull requests in bulk.
Background
Like many other projects, collectd used the name master for the default
development branch. We made the decision to use main instead going forward.
Creating a new branch and changing the default is easy, but there were over 100
open pull requests referencing master as their base branch, i.e. the branch
they wanted to get merged into.
This tool was written to change the base branch of all these pull requests
efficiently.
Usage
Get a Github OAuth access token
Open the settings menu (your icon in the upper right-hand corner → Settings)
Developer Settings → Personal access tokens → Generate new token
Add a note that lets you identify the use of this token, e.g. "Migrate pull requests from master to main".
Under "Select scopes", check "public_repo – Access public repositories"
Copy the token
Optional: Implement command line flags for this tool and send a PR ;-)
Alternative: Update the constants at the beginning of the main.go file.
