Merge lp:~canonical-platform-qa/unity8/1421009-hangs-on-boot into lp:unity8

Add a dep8 test to reproduce bug #1421009

This proposal add a dep8 test to reproduce https://bugs.launchpad.net/ubuntu/+source/unity8/+bug/1421009

It can be run from a unity8 branch with:

$ adt-run -B --unbuilt-tree . -o ../results --- ssh -s adb -- -p <pass{word,phrase>

It's not ready to land as-is, when run on the desktop is doesn't test unity8 (but it probably could with some more work).

I thought it was worth sharing since it provides a way to put a phone into the
broken state for developers to investigate.

Very useful to have! Although with reboot 60 or even 100, because of the findings of the fluctuation of the problem.

Bumped to 100 in revno 1750.

"needs fixing" for the overzealous Depends:, the others are just simplification. Thanks!

Is this something we would actually want to land or was just for debugging that bug?

A bit of both but the plan is unclear :-/

It was useful to reproduce the bug and validate the workaround.

As such it sounds like a good regression test and can be used to gate the real fix.

I'll mark it wip until a decision is taken.

Further simplifications recommended by someone who knows how to write shell ;)

1751. By Vincent Ladeuil on 2015-04-28

We test unity8, depends on it to avoid installing too much.

1750. By Vincent Ladeuil on 2015-04-28

In at least one case, the hang happened after 54 reboots so doubling that number to validate the workaround in silo 17 and guard against regressions.

1749. By Vincent Ladeuil on 2015-04-24

Add a dep8 test reproducing https://bugs.launchpad.net/bugs/1421009.
