Branch names and confusion
We have a variety of branches at Mozilla, here are the main ones that we see alerts on:
- Mozilla-Inbound (PGO, Non-PGO)
- Autoland (PGO, Non-PGO)
- Mozilla-Beta (all PGO)
Linux and Windows builds have PGO, OSX does not.
When investigating alerts, always look for the Non-PGO branch first. Usually expect to find changes on Mozilla-Inbound (about 50%) and Autoland (50%).
The volume on the branches is something to be aware of, we have higher volume on Mozilla-Inbound and Autoland, this means that alerts will be generated faster and it will be easier to track down the offending revision.
A final note, Mozilla-Beta is a branch where little development takes place. The volume is really low and alerts come 5 days (or more) later. It is important to address Mozilla-Beta alerts ASAP because that is what we are shipping to customers.
