GitHub Improves Performance of Large Pull Requests
WHY IT MATTERS
This improvement enables teams to review and ship large changes with less risk, making the development process more efficient and reliable.
What happened
GitHub has rebuilt the pull request view in the GitHub Copilot app to handle large pull requests efficiently.
The new design uses virtualization to render a large diff at speed and addresses the challenges of comments, which can change height after first paint.
The solution involves splitting the document's height into two independent domains: deterministic code height and dynamic block effective heights.
