Description

Incrementally roll out Mobile-Content-Service and other RESTBase endpoint usage by the Android Production app. (See T118965 for beta app roll-out.)

This will be done via the MobileApp extension which provides a remote config mechanism.
We are going to add a new key restbaseProdPercent and increment the percentage of production app installations eligible for using the new endpoints. The config file is located at https://meta.wikimedia.org/static/current/extensions/MobileApp/config/android.json.

Stage 1: 3/24/2016: 2%
Stage 2: 3/28/2016: 25%
Stage 3: 4/4/2016: 50%
Stage 4: 4/11: 100%

After deployment check https://meta.wikimedia.org/static/current/extensions/MobileApp/config/android.json
Will need a cache purge on https://en.wikipedia.org/static/current/extensions/MobileApp/config/android.json. (note the en instead of meta)

echo "https://en.wikipedia.org/static/current/extensions/MobileApp/config/android.json" | mwscript purgeList.php

@bearND, we are planning to switch RESTBase traffic from Eqiad to Codfw next week: T127974. While this is fairly straightforward, we should time it so that it doesn't coincide with the app ramp-up.

@GWicke Good point. When is it done? Is moving everything a week later ok?

+1 to waiting until the RESTBase move to codfw is complete before beginning the rollout to the stable Android app. That'll give us plenty of time to get our outstanding work merged/deployed/tested without rushing to meet a rollout deadline.

https://gerrit.wikimedia.org/r/#/c/275702/, for example, is a pretty important fix I'd like to see get in before we start the rollout.

When is it done? Is moving everything a week later ok?

Switching the public traffic will be a single puppet change to update the varnish config (RB and Parsoid are active in both eqiad and codfw), but there are a few other services (including mobileapps) which we'll then need to reconfigure to use the codfw RB as well. It should not take more than an hour or so total, with no user-visible impact.

The exact time will be finalized tomorrow. If we switched on Tuesday, then technically the roll-out could go ahead on Thursday. I just don't want both to happen at the same time.

OK, we could do a SWAT deploy a couple of days after the switchover is complete if we want more control over when this gets out.

Update on the DC switch-over: This is scheduled for three hours tomorrow morning European time. After that, we'll switch back to eqiad. No further switching is planned until later in April, when MediaWiki should be ready. See T127974 for details.

We are going to implement a solution for T118306 today on the RESTBase side. This will then likely make it to production on Monday.

It's merged and synced but for some reason not showing up yet, even with cache busting query parameters and purging the cache. We might need to give it some more time.
