860588 - reset birch and cypress twigs in advance of the b2g workweek

Status: RESOLVED FIXED

(Release Engineering :: General, defect)

Description

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

Summary of lots of emails + inperson discussions. 

In preparation for next week's b2g workweek, I've reserved the birch + cypress branches. Please:

1) reset both of these repos to tip of m-c
2) mark these trees closed on tbpl.m.o
3) configure birch to run all builds+tests that mozilla-inbound does.
4) configure cypress to run only linux, b2g builds+tests. If we find we are better served by running all like mozilla-inbound, we can revisit.
5) raise the priority of birch+cypress above all other branches, but still below releases.

Can we keep it to just birch? In the thread we did not want to use the multi inbound approach.

Comment 2

[Phil Ringnalda (:philor)]

I hear rumors of wanting periodic PGO rather than on-push, too.

Comment 3

[Ryan VanderMeulen [:RyanVM]]

More suggestions:

Run debug builds only the ec2 builders (ie Linux/Linux64). We'll want some leak checking ability, but all platforms is probably redundant, especially with semi-frequent merges to m-c.

Don't run checktests on OSX and Windows (all builds) to speed up the turnaround time. Consider disabling checktests on Linux/Linux64 desktop B2G builds as well.

Discussions continue, but meanwhile, lets setup both, so we have both ready for Monday, regardless of what we decide in the meanwhile.

I think this is done.

Comment 6

[Chris AtLee [:catlee]]

Just had a thought - do we want unagi engineering builds (ala bug 820594/bug 848282) on these branches?

Comment 7

[Ryan VanderMeulen [:RyanVM]]

I was thinking about that earlier today too, but I don't think it's necessary. My assumption is that people will continue to use builds off m-c or more likely b2g18 as usual next week, so we only need to maintain enough coverage on birch to make sure we don't merge any bustage over to m-c.
