1400546 - ./mach try should select artifact builds based on the files touched in all the non-public csets it's pushing

Status: NEW

(Developer Infrastructure :: Try, enhancement)

Description

[:Gijs (he/him)]

Right now I use hg push-to-try. But if we're going to require ./mach try, I need a way to get artifact builds even if my tree happens to not be using them, not just a way to turn them off if they are in use in my local tree. The easiest would be if ./mach try just did this automatically. This would also save on time spent running full builds on try when that is unnecessary, and reduce turnaround time for trypushes.

I'll file a separate bug for an explicit switch.

... so apparently the help is just badly organized, so I didn't realize that there was anything besides a --no-artifact switch. Anyway, I filed bug 1400548, but this:

still seems like a good idea to me, it just doesn't need to block requiring ./mach try.

Fun fact: automation scheduling already looks at files touched in the push (non-public ancestors on Try) to influence scheduling. It just doesn't interact with Try scheduling that well.

I'm pretty sure we have a few bugs open wrt artifact build usage and scheduling. I know we've certainly talked about opting in to artifact builds automatically if possible...

Yep, support for that is in progress in bug 1383880 (which is ironically blocked by a bug in artifact builds)
