1394471 - missing talos jobs on stylo builds

Status: RESOLVED FIXED

(Testing :: Talos, defect)

Description

[Joel Maher ( :jmaher ) (UTC -8)]

I am looking on mozilla-central to ensure we have all talos jobs running as expected, I found 3 anomalies:

linux64-stylo is missing the 'g2' job, but linux64-stylo-seq runs it just fine?

linux64-qr is missing the 'g1' and 'g2' jobs.

:kats, do you know if there is a reason for the qr builds missing g1 and g2 ?

Comment 2

[Joel Maher ( :jmaher ) (UTC -8)]

:jryans - do you have history on why g2 isn't on for linux64-stylo?

Comment 3

[Kartikaya Gupta (email:[e-mail])]

Yeah, they were failing. I have bug 1390875 on file for getting them running.

That's quite strange!  I am not aware of it being disabled on purpose...  It seems like it should be enabled from the TC configuration, unless I am misreading...

enable linux64-stylo g2

-----------------------------------------------------------------

It doesn't look like it worked from your try run, there's no runs on linux64-stylo.

I don't think it's related to `talos-g2-stylo`.  Linux Stylo uses a different way of configuring Talos runs from Windows / macOS Stylo.

The test platform `linux64-stylo` includes[1] the `talos` test set, which is the "regular" Talos tests, such as `talos-g2`, not `talos-g2-stylo`.

I believe the step that actually enables Stylo for these Linux Talos runs is reading the BB platform name[2].  Looking at a g1 log[3], it runs the suite named `g1-e10s` (not `g1-stylo-e10s`), so that seems to confirm that Stylo is not being enabled via the Talos suite on Linux.

So, it seems something else is preventing g2 from running, but I am still sure what it is...

It looks like it's running (at least on the try push in comment 5) but it's hidden by default. See https://treeherder.mozilla.org/#/jobs?repo=try&revision=02d1e3d05586e521d0db449ca5347746c7e39b83&exclusion_profile=false

In fact it's running on m-c as well: https://treeherder.mozilla.org/#/jobs?repo=mozilla-central&revision=3529b653ede26f990eb7320649015294ad0f8e76&filter-searchStr=talos%20stylo%20g2&group_state=expanded&exclusion_profile=false

Oh wow, thanks for finding this!  I wasn't aware that had been done.  Looks like it's green now, so I'll discuss with sheriffs to unhide it.

thanks for pointing out the obvious- and I found the problem, we had a treeherder exclusion for linux64-stylo g2*; I removed that and now  we have the full set of talos jobs showing up on mozilla-central.
