All changes should be associated with a bug. The WebKit project is currently using Bugzilla as our bug tracker. Note that multiple changes may be associated with a single bug.
The WebKit Project strongly recommends contributors use Tools/Scripts/git-webkit to generate pull requests. See Setup and Contributing Code for how to do this.
If a contributor wishes to file a pull request manually, the template is below. Manually-filed pull requests should contain their commit message as the pull request description, and their commit message should be formatted like the template below.
Additionally, the pull request should be mentioned on Bugzilla, labels applied to the pull request matching the component and version of the Bugzilla associated with the pull request and the pull request assigned to its author.
