1222077 - Schedule tasks on certain files being changed

Status: RESOLVED FIXED

(Firefox Build System :: Task Configuration, task)

Description

[Armen [:armenzg]]

We spoke about scheduling Mozharness tests only when Mozharness code is touched by a changed.

We can analyze the json push for which files are touched:
https://hg.mozilla.org/integration/mozilla-inbound//json-pushes?changeset=317f1490ee1f222849e4c95e565dcd8d96d28032&full=1

If we can structure this in some suitably generic fashion, so that
individual jobs can be included or excluded depending on modifications
to particular sub-trees specified in the YAML files, that would be
pretty awesome.

Found in triage.

Dustin: do we have onchange events now?

Comment 2

[Dustin J. Mitchell [:dustin] (he/him)]

Well, onchange would be a DOM event :)

But, yes, this could be handled with the SCHEDULES stuff.  I think that `mozharness` would be an exclusive component, and then the relevant files would be tagged in moz.build as SCHEDULES.exclusive = ['mozharness'].

Armen, do you want to set that up?

[Armen [:armenzg]]

No, I have no involvement with Mozharness these days.
