As someone who was high on the list of try server usage for two
weeks.... My problem was a test I tried to fix for both e10s and
non-e10s, and it timed out _sometimes_ on _some_ platforms even
depending on debug/release build. It was a whack-a-mole game by
fiddling with the test and a complex patch. I did stop old builds but
I did not run only the test in question but the rest of them as well
because of the invasive nature of the patch the whole thing was
sitting on. Probably I could have been smarter, BUT...
What would have helped me a lot in this case and most cases when I
rely on the try server is the ability to push a new changeset on top
of my previous one, and tell the server to use the previous session
instead of a full rebuild (if there is only a change in the tests
that's even better, no rebuild at all) and then tell the server
exactly which tests I want to re-run with those changes (as it can be
an empty set this can be used to trigger additional tests for a
previous push). This could all be done by an extensions to the try
syntax like -continue [hash]. As an addition this follow up push would
also kill the previous job.
Maybe there is already such functionality available, just I'm not
aware of it (I would be so happy if this were the case, and would feel
bad for the machine hours I wasted...), if so please let me know.
You can do that more or less with moz-ci. IIRC, the setup is detailed
somewhere on Armen's blog (CCed, he might be able to point you there)
Mike
It is possible for Buildbot jobs (not TaskCluster) with a python script,
you need to specify where to find the builds and test bundles are [1]
However, this is not optimal as it is.
You need to upload the new test bundle somewhere and point to that.
I've filed this as https://bugzilla.mozilla.org/show_bug.cgi?id=1268481
and tracking it under making try awesome meta bug.
