839230 - Turn off unagi stable builds

Status: VERIFIED FIXED

(Release Engineering :: General, defect, P2)

Description

[Nick Thomas [:nthomas] (UTC+12)]

From a releng point of view we have two 'nighty' builds of the (nominally) same source, only differing by 
 * the builder name (unagi vs unagi_stable)
 * the update channel baked in (nightly vs beta)
 * the update channel they get auto-published (nightly vs betatest, manual push to beta for the latter)

We can simplify that to one build with beta baked in, published to the nightly channel for QA. The only change in process for QA would be running a script after flashing to force the nightly channel, which has been agreed to.

Changes channel to nightly in build and socorro manifest, removes stable config.

Removes all traces of unagi-stable, which vanishes the b2g_mozilla-b2g18_unagi_stable_nightly builder. Passes checkconfig and comparing master dumps, not used on a master yet.

Works as expected.

* Verified uploads - nightly bits to b2g/nightly/mozilla-b2g18-unagi/YYYY/MM/..., snippet to nightly location  (this failed in staging because dev-stage isn't set up right, but it eyeballs ok)
* Verified that nightly build is on the beta channel using adb

Attachment: channel-setup.sh script

This is based on the old dogfood script. 

First time steps
* download to your machine as channel-setup.sh
* chmod +x channel-setup.sh

Usual usage
* flash build onto device
* ./channel-setup.sh

First nightly with the changes is
https://pvtbuilds.mozilla.org/pub/mozilla.org/b2g/nightly/mozilla-b2g18-unagi/2013/02/2013-02-12-23-02-02/

Verified:
* that build has beta channel baked in
* that build is offered on the nightly channel
* updating from https://pvtbuilds.mozilla.org/pub/mozilla.org/b2g/nightly/mozilla-b2g18-unagi/2013/02/2013-02-12-07-02-05/ on nightly gets you the right revisions post-update, and channel has changed.

So code is working as expected.

To do:
* announce to mailing lists
* update promotion docs

All done.

Comment 11

[Tony Chung [:tchung]]

Verified fix.  OTA and flashed from a beta build, and ran script in comment 8 to get onto "nightly" channel.

edmorley: FYI, we no longer need the config for stable builds in TBPL.
