789373 - use the new --disable-ion flag for specific b2g-related builds

Status: RESOLVED FIXED

(Release Engineering :: General, defect)

Description

[John O'Duinn [:joduinn] (please use "needinfo?" flag)]

Per meeting w/dvander, dmandelin:

We need IonMonkey landed on mozilla-inbound, and then mozilla-central for the FF18 release. We also need to make sure that IonMonkey does not disrupt B2G work also now happening on mozilla-central. This means we need IonMonkey enabled and used by default on all builds *except* a specifically chosen list of builds. To do this:

1) dvander will create new "--disable-ion" flag and land it. Bug#789319 has details.

2) RelEng will ignore this new flag for Firefox builds, so FF18 users will see IonMonkey goodness once it lands. RelEng will update mozconfigs to use this new flag for these specific Fennec, B2G desktop builds and B2G builds in https://hg.mozilla.org/mozilla-central:
config/mozconfigs/ics_armv7a_gecko/*
(not sure if this is complete list of config files)

3) dvander will land IonMonkey on mozilla-inbound, and migrate to mozilla-central.

4) Until RelEng have B2G tests running on B2G builds, RelEng will generate some android builds with, and also without IonMonkey. This will require us to create a new type of build, for example: "android-no-ion". Each of these android builds then needs the usual Android tests run on it. This will also require changes to tbpl. 
Note: The "android-armv6" and "android-x86" builds should only be created with "--disable-ion", as IonMonkey is not relevant there. 

5) After RelEng has B2G tests running on B2G builds, we will disable the new "android-no-ion" builds.
Note: to be explicit, android-armv6 and android-x86 should continue to be run with "--disable-ion", as IonMonkey is not relevant there.

I think it would be simpler to enable android tests on the IonMonkey branch, and keep ionmonkey on for android there and off on m-c.  Then the android tests on the ionmonkey branch would be an indicator of android testing status with ionmonkey on.

However, if we're looking to get per-checkin test results on m-c for *non*-ionmonkey checkins (but with ionmonkey on), this might be the best solution.

We really want to land IonMonkey on mozilla-central pref'd on so it can ship with desktop and mobile Firefox 18. Our concern is not conflicting with B2G's development. I don't think we could ship IonMonkey if it's pref'd off on m-c.

Comment 3

[Phil Ringnalda (:philor)]

Tree rules in a nutshell: if it's visible on m-c, you cannot break it, so it must also run on try and on everything that merges to m-c. If there's visible android-no-ion on m-c, then it has to be on inbound, and fx-team, and services-central, and build-system, and try, and whatever else I'm forgetting. Do we actually have the tegra capacity to basically double the test load?

A fun alternative: run them hidden and on inbound only, for the retrospective pleasure of the b2g folks to look back at what broke them, the same system that jetpack uses.

Comment 4

[Ed Morley [:emorley]]

If we do go ahead with this idea (I personally not liking the sound of doubling our tegra load and also sheriff android manual starring time, but oh well), then we'll need a bug to add TBPL support for the new android-no-ion builds, once the name has been confirmed:

Comment 5

[David Anderson [:dvander] - inactive, e-mail if emergency]

What is the ETA for completing step 2 of comment #1?

We've completed step #1 on our end, and are still blocked on landing IonMonkey.

Comment 6

[Phil Ringnalda (:philor)]

Isn't step 4, the misnumbered one that needs to be 3, the killer? Step 2 doesn't even require someone who knows anything about b2g, just someone with a mozilla-central tree and the knowledge (which can be gained by opening logs off tbpl and looking for the "got mozconfig" buildstep) that they are in /b2g/config/mozconfigs/ics_armv7a_gecko/* rather than in /config/.

This disables IonMonkey for the ICS-based B2G builds as well as the Armv6 Android builds - I believe that covers all of the places we want them off.

You are correct, anyone can do such modifications now. You can even push them to try!

Any pushes that come after my push to m-c will have ionmonkey disabled for ICS b2g builds & Android armv6 builds - if that's what you mean.

TBPL is just a dashboard, it doesn't compile anything or run any tests. Buildbot is what schedules the builds/tests; 'tinderbox (builds)' is/are the (albeit slightly out of date) name typically given to what is produced on each push.

All that has landed is the part that deals with:
(from comment 0) "Note: The "android-armv6" and "android-x86" builds should only be created with "--disable-ion", as IonMonkey is not relevant there." 

The rest of comment 0 step 4 (ie: Android on armv7) still needs buildbot-config patches to create both 'android' and 'android-no-ion' builds. The bug to add TBPL parser support for this new build name (mentioned in comment 4) hasn't been filed yet either.

However, I'm still not convinced the current plan is the best way forwards - given as yet, no one has responded to the capacity concerns in comment 3, comment 4 & comment 6.

Comment 14

more disabling

To be clear, this will disable ionmonkey across the board for b2g (adding desktop) and android fennec (adding x86 + armv7).

Per dvander, we want to turn it back on for armv7 fennec but we need to either solve the no-ionmonkey builds/tests or the b2g testing first.

Attachment: android-noion mozconfig

This simply copies mobile/android/config/mozconfigs/android/nightly to mobile/android/config/mozconfigs/android-noion/nightly .  Since the former currently has --disable-ionmonkey, that should be sufficient.

The sooner this lands, the sooner this will merge to project branches; it'll also make staging the builds easier.

This needs to land after:

Attachment: [configs] android-noion builds and tests

I ran a couple staging android-noion builds which:
* are named correctly
* uploading to the android-noion dir
* using the proper mozconfig
* are only on m-c and m-i per email thread
* sendchanged

Then I brought up the staging test master, and verified
* they're named correctly
* respond to the corresponding sendchange
* only on m-c and m-i per email thread
* not running reftests or crashtests per email thread (jsreftests are on though; is that right?)

I didn't actually run any tegra tests; I can run those tests if you think there might be reason to.

Why are we swapping to a different update_platform for Android-debug? If we do this, imo, we need to fix the debug builds on aus to continue getting updates.

Indeed, if these are going to be builders that are intended to be unhidden we should have try support for them or else sheriffs will hide them whenever they break.

Is there support in the build system for this? Unfortunately, this isn't a source of truth for update platform names, it merely reflects what the build system gives us. If we want nightly builds there's probably a few other things we need to do too.

We already did this with android-xul, and I think we're still doing it with android-armv6.  I'm less concerned with having a good location for noion updates as I am not polluting android armv7 updates.

On IRC, Ben said he noted all of his concerns.
I don't like this either, but it's not any less programmatic than the rest of mozilla-tests/config.py and it's certainly a faster way to get where we want to [temporarily] go.
