594281 - Consider adjusting priorities for builds and unit tests

Status: RESOLVED FIXED

(Mozilla Messaging Graveyard :: Try Server, defect)

Description

[Mark Banner (:standard8)]

If we get several builds all queued in the space of one build, unit tests get delayed for a long time. For example:

1) Queue three builds a, b and c.

2) a runs to completion, tests for a are queued, but b was queued first so that runs first.

3) b finishes, tests for b are queued, but c was queued first still

4) c finishes, tests for a b and c are then run.

This can delay unit tests for several hours for the first run.

As tests are typically shorter than builds, I think we should be making sure they happen earlier.

Either that or we need more builders on try ;-) (though I think the general capacity doesn't warrant it at the moment).
