API 15 work might have changed the file names? bug 1155801 and bug 1219094

Yes just looked at the archive and the folder names changed on the 29th. https://ftp.mozilla.org/pub/mobile/nightly/2016/01/2016-01-29-03-02-06-mozilla-central-android-api-15/ for example.

Fallout from Bug 1219094.

Thanks for the investigation - I'm looking at it.

So, Kevin is right, this changed on 2016-01-29 for archive.m.o too:

https://archive.mozilla.org/pub/mobile/nightly/2016/01/

We also have an issue with taskcluster, for the same reason - api-11 was replaced by api-15 on mozilla-central. No luck, mozilla-inbound still have both:

https://tools.taskcluster.net/index/#gecko.v2.mozilla-inbound.latest.mobile/gecko.v2.mozilla-inbound.latest.mobile

So I am not sure what is the right thing to do for that. I found that if I use api-15 for a push timestamp >= 1454027413 (roughly 2016-01-29 00:35:50) this makes things work on m-c, and on m-i. So that mean that pushes before this date will use api-11, and api-15 after (for every branches).

I will apply that logic, unless someone see any error in the reasoning.

One other thing, we still have fennec-23 registered as a possible mozregression application. Roughly:

fennec-23 is for android-api-9 and older android-api
fennec is for android-api-11 and now android-api-15

Does that make sense ? (I am not really qualified to judge that :)) Do we still want to support fennec-23 ?

Monday should be fine. The regression that I thought had started in that time actually was older.

This all makes sense, ship it!

Landed in https://github.com/mozilla/mozregression/commit/3fbd0421611a5f5816c7c50f4692a69c20d956c3.

I will do a release later today.

Does bug 1246844 block mozregression from working on Android? Can you lock the version of mozdevice to one before the root requirement?

No, it should work as usual - the bug is here so we can try to leverage the use of root in the adb calls.
