1635940 - Implement a fallback for bugbug optimization strategies

Status: RESOLVED FIXED

(Firefox Build System :: Task Configuration, task, P2)

Description

[Andrew Halberstadt [:ahal]]

If we want to use the bugbug service on autoland, we should have a fallback in the event the service goes down for an extended period of time. Currently the decision task would just fail and sheriffs would need to close the trees.

Instead we should fallback to using SETA or some other algorithm if there's a bugbug timeout. Having this fallback will allow us to get the optimizer on autoland sooner.

Can we have a daily stored artifact with information of what should be scheduled?
I would love to kill SETA :)

I think there's still some benefit in running the SETA shadow-scheduler as a benchmark even after it gets replaced. Don't worry, we can turn it off soon in a few months :p
