1640047 - Don't schedule everything when the known tasks returned by bugbug are bogus

Status: RESOLVED FIXED

(Firefox Build System :: Task Configuration, task)

Description

[Marco Castelluccio [:marco]]

There were 15 pushes between Monday and Tuesday where we scheduled all tasks despite what bugbug selected, because for some reason the known_tasks returned by bugbug was an empty list.
We should protect against bogus values of known_tasks, and just assume that, whenever it is an empty list or a too small list, there was some problem.

N.B.: Bugbug retrieves the known tasks from https://firefox-ci-tc.services.mozilla.com/api/index/v1/task/gecko.v2.autoland.latest.taskgraph.decision/artifacts/public/target-tasks.json whenever its HTTP service is started (either on deploy or after daily restarts). The most likely explanation seems to be that at some point a broken patch, making target-tasks.json empty, made it to autoland.
