[system_tests] [ubuntu] manage extra_deb_repos with custom priorities

[Bogdan Dobrelya]

When there is some testing repo with some package under test, sys tests should be able to ensure the proper pinning for this extra deb repo.
The issue is, for example, when I'm going to test a new pacemaker build from OSCI testing repo:

EXTRA_DEB_REPOS="deb http://obs-1.mirantis.com:82/trusty-fuel-6.1-stable-5388/ubuntu /"

the pacemaker package cannot be updated due to the main MOS repo has a higher pin and pushes the older version of pacemaker.

Also, internal docs at https://mirantis.jira.com/wiki/display/PRD/External+Ubuntu+Repositories do not have details about extra_deb_repos usage.

So, please:
1) Check if it is possible to define the repo priorities for our system tests jobs
2) Fix the internal docs about how to use EXTRA_DEB_REPOS with priorities
3) Provide extra_deb_repos examples (like in the comment #3 below)
4) Make the publicly available docs at Fuel wiki/dev docs as well.

As far as I can see from the sys test logs http://pastebin.com/q2M7NPMm, the priorities are hardcode.

Here is an output from my lab http://pastebin.com/B8En6QDu
It reports the former extra-0 repo pin is 1050 but the real priority reported by apt-cache policy is 500, hence the pacemaker package cannot be updated to the version under test

Bogdan,

please check parameters in this job http://jenkins-product.srt.mirantis.net:8080/view/custom_iso/job/6.1.custom.ubuntu.bvt_2/build

Thanks

Also, you got default pin priority for your extra repository, because it's flat.
Try to use the following value for EXTRA_DEB_REPOS:

http://obs-1.mirantis.com:82/trusty-fuel-6.1-stable-5388/reprepro/ trusty main

Here is how it can be quick-fixed for system tests jobs (keeping pins as hardcodes)

root@node-1:~# cat /etc/apt/preferences.d/extra-0
Package: *
Pin: release a=/
Pin-Priority: 1050

Package: *
Pin: origin "*obs*mirantis*"
Pin-Priority: 1150

root@node-1:~# apt-cache policy pacemaker
pacemaker:

@Vitaliy, thank you, that works.
Let's please update the docs with example then

[Bogdan Dobrelya (bogdando)]

lowering to high as it isn't a blocker anymore

[Bogdan Dobrelya (bogdando)]

This one is invalid as we don't have the extra_deb_repos option anymore
