Is this still blocked on something? Not trying to rush you or anything -- just wondering if I need to chase someone :)

Blocked on me doing the next steps. :)

We're branching soon, so I'm on health plan mode now. Will get back to this next week.

Sounds good!

Sorry for me being super slow with this. Taking this now to the top of my queue.

Btw, looks like tests have been failing recently on this bot. Is there any bug attached to that?

Seems that crrev.com/2300703005 is the reason, looking into it.

Thanks both! Having the bot on the main waterfall will help to prevent exactly that kind of breakage :)

Sami, the headless trybot is now available for manual runs in code reviews under "master.tryserver.chromium.linux" on Choose trybots.

I'm also sending out https://codereview.chromium.org/2342813002 for review, so we start running it automatically on 10% of commits.

[modify] https://crrev.com/7d6811c4c58a9e280bca7bf65a8dfde001bef42a/infra/config/recipes.cfg

I want to investigate why sometimes the bot takes too long to compile, since this could be a blocker to have it on CQ and the main waterfall.

From issue 633985, Sami noted:

~~~
Here's two traces from the Linux x64 builder and the Headless builder around the same time:

Linux: http://chromium-build-stats.appspot.com/ninja_log/2016/08/03/build48-m1/ninja_log.build48-m1.chrome-bot.20160803-082648.12505.gz/trace.html

Headless: http://chromium-build-stats.appspot.com/ninja_log/2016/08/03/slave16-c1/ninja_log.slave16-c1.chrome-bot.20160803-094644.11126.gz/trace.html

First of all looks like Headless is using -j50 and Linux has -j160 which probably explains some of the difference.

Each object also takes a lot longer to build on the Headless bot. My unsubstantiated theory is that since Headless probably uses unique compiler flags, it doesn't benefit from goma's caching and effectively needs to build every affected file from scratch. Another possibility is that it somehow has less bandwidth to goma. Maybe the machines are different too?
~~~

The number for the -j parameter comes from here: https://chromium.googlesource.com/chromium/tools/build/+/master/scripts/slave/compile.py#340

would it make sense to special-case it for the headless builders too?

+cc'ing some potential reviewers of that change.

Is it possible for you to point out builds in the next time?  It requires me certain processes to find out compiler_proxy.INFO.

Linux: gs://chrome-goma-log/2016/08/03/build48-m1/compiler_proxy.build48-m1.chrome-bot.log.INFO.20160803-081125.12513.gz

compile: # of tasks: 33475
   replies:
     local finish, no goma : 31
     should fallback : 24
     goma success (cache hit) : 32756
     local finish, abort goma : 118
     goma success : 546

Headless: gs://chrome-goma-log/2016/08/03/slave16-c1/compiler_proxy.slave16-c1.chrome-bot.log.INFO.20160803-080342.11134.gz

compile: # of tasks: 0


Headless does not use goma.

As far as I can see in  https://build.chromium.org/p/tryserver.chromium.linux/builders/linux_chromium_headless_dbg/builds/1/steps/generate_build_files%20%28with%20patch%29/logs/stdio, and https://chromium.googlesource.com/chromium/src.git/+/master/build/args/bots/tryserver.chromium.linux/headless_linux_dbg_trybot.gn, you seems to forget to write use_goma = true.

D'oh! ... getting ready a CL to fix that.

is looking quite good after starting the experiment.

Paweł, should we ramp it up now? What's a good number to go up from the current 10%?

Ping, any change we could bump the percentage a bit? We're seeing about a couple of build breakages a week when stuff sneaks past the builder.

This bot seems to be chugging along happily (at 100% of cq):

https://build.chromium.org/p/chromium.fyi/builders/Headless%20Linux%20%28dbg%29?numbuilds=200

Could we make it block the cq now?

The headless bot isn't doing what you might expect. args_file in a mixin in mb currently has no effect, though +dpranke has a CL out to fix that. The headless mb mixin relies on that behavior working: https://codesearch.chromium.org/chromium/src/tools/mb/mb_config.pyl?rcl=45196266f164836fca6d41e8f9cfad0eee0b91a6&l=1754

Moving this to CQ blocking should wait until that fix has landed.

#41: Interesting! Has that always been the case? Maybe about a month ago (before we had --headless) these tests should have failed if they weren't truly compiled in headless mode.

I'm not sure how long args_file hasn't worked in a mixin, but it looks like headless has only been using that feature since 2017-02-07: https://chromium.googlesource.com/chromium/src/+/23c2f1952f5845194633c1ccd50e7408576c7465

Oh, didn't realize the mixin wouldn't work when I tried to simplify the configs :O

If that fix from dpranke@ will take a while, I'm happy to revert that patch and reland it after dpranke@'s fix.

Okay, see what Dirk thinks. Agreed that if mixins take some time to get in place, let's revert back to the old config to make sure we're testing the right thing.

*let's see

It should land today, so I'd just leave it.

Hey, any news about the patch in #47?-) Not sure where to look for it.

It landed a while ago. You can see the latest build is expanding things properly:

https://luci-logdog.appspot.com/v/?s=chromium%2Fbb%2Fchromium.fyi%2FHeadless_Linux__dbg_%2F21401%2F%2B%2Frecipes%2Fsteps%2Fgenerate_build_files%2F0%2Fstdout

whereas an older build like

https://luci-logdog.appspot.com/v/?s=chromium%2Fbb%2Fchromium.fyi%2FHeadless_Linux__dbg_%2F20000%2F%2B%2Frecipes%2Fsteps%2Fgenerate_build_files%2F0%2Fstdout

didn't have the import().

Woo, excellent, thank you! As far as I can tell there's now nothing else blocking making this bot cq-blocking, right?

The builder is still on the FYI waterfall. We should move it to the main waterfall first. I can post a CL for that later today.

The current FYI builder is a debug builder. The tryserver is a release tryserver.

I'd rather not have a release tryserver in the CQ without also having a release waterfall builder. Can we flip the FYI builder to release, or do you see a lot of debug-only failures and want to have both?

skyostil@ can you take a look at my questions in #c52?

Turning the FYI builder from debug to release sounds fine to me. Breakage so far has mostly been either failing to build or failing some tests.

Friendly ping -- was there something else blocking making this bot block the CQ?

Nothing other than me having the time to make the changes. I'll post a CL to make the builder non-experimental now, and follow up with one to move the waterfall builder as well.

Thank you! Not trying to rush anything, just checking in :)

Make linux_chromium_headless_rel non-experimental in the CQ.

The bot has been running as a 100% experiment for a long time,
which is just a waste of resources :). This CL makes the bot
a full-fledged member of the CQ, meaning that failures will
block a patch from landing.

The waterfall bot is still on the FYI waterfall (Headless Linux
(dbg)) and we should move it to the main waterfalls (and make it
a release bot to match the CQ config), but I think we can get
away with not doing that before landing this, as long as I get
to it later today.

As far as I can tell we're done here? Thanks for the help everyone!
