For beta55 we'll likely want a staged rollout of the first few builds, since they'll be fresh off nightly.

We need a patch similar to the one in bug 1354038. This is a good occasion to get familiar with Taskcluster's taskgraph. OBJECTIVE Modify the task definition of push-apk[1], so the payload contains: > "google_play_track": "rollout", > "rollout_percentage": 10, Note: the value of rollout_percentage will be defined by release management PROPOSED SOLUTION The line at [2] defines what Google Play Track we're going to use. We'll need a new key/value at [3]. TESTING PROTOCOL 1. Download the parameters file of a Fennec release definition task[4], and save it to parameters-beta-candidate-fennec.yml 2. Execute `name='beta-candidate-fennec' ; ./mach taskgraph optimized --json -p parameters-$name.yml > $name.json` 3. Open beta-candidate-fennec.json and look up "push-apk". See the new payload.

Hi, I would like to contribute. I'm very new here, I will let you know once I get the build env ready.

Given that this is a Dawn blocker, do we really want to use automation to do this? Is it too painful to do by hand for the transition?

AIUI currently automation is set up to push beta builds at 100% immediately. If we can disable that for the first few beta55 builds I'd be fine with uploading manually if it's easier.

Normally this can wait since 55.0b1 is still a few weeks ahead, but if you want to land this sooner (on nightly), I think :aki is your best bet for a r? redirect. Alternatively I can also look into it ;-)

Like discussed a few weeks ago, we might want to test the rollout on 54.0b12 or b13. Do you still agree with that? If so, I'd suggest to keep the bug open until we uplift attachment 8865837 [details] to beta.

Comment on attachment 8865837 [details] Bug 1358420 - use staged rollout for fennec beta builds Hi Gerry, as discussed in email: Approval Request Comment [Feature/Bug causing the regression]: dawn [User impact if declined]: we won't have a chance to test staged rollout for fennec beta before 55.0b1 [Is this code covered by automated tests?]: no [Has the fix been verified in Nightly?]: n/a [Needs manual test from QE? If yes, steps to reproduce]: no [List of other uplifts needed for the feature/fix]: none [Is the change risky?]: not really [Why is the change risky/not risky?]: patch is pretty simple, and the worst case is either the upload to google play fails (and we can fallback to manual upload), or the staged rollout doesn't work (which is fine for beta54) [String changes made/needed]: none

Also, the plan is to back this out of beta54 once verified to work, so future 54.0bN builds keep going out at 100%.

Comment on attachment 8865837 [details] Bug 1358420 - use staged rollout for fennec beta builds This is for Dawn purpose. We have to make sure the staged rollout for fennec beta works. Beta54+. Should be in 54 beta 10.

rollout was successfully tested with 54.0b10, so we won't need this on beta54 anymore. Ryan, can you back this out of m-b? Thanks!

Backed out from Beta55 at Julien's request. https://hg.mozilla.org/releases/mozilla-beta/rev/544e640571f4
