Effectively communicating tree closure
It is considered best practice to annotate the tree status with information about what is known about the status of build failures. For example, automatic closure messages such as...
Tree is closed (Automatic: "compile" on "Webkit Mac Builder" from 12345:
f...@chromium.org)
... should be changed to:
Tree is closed (compile -> foo)
... to indicate that committer 'foo' has been notified of the problem and is looking into it. Once a fix has been checked in, sheriffs often use status:
Tree is closed (cycling green)
... to indicate that a fix/revert has been checked in and the tree will likely be opened soon.
