missing OS targets vivid etc

[tfoote]

I'm running on vivid and there are lots of warnings due to vivid not being in this file. Such as the following:

[WARN] [WallTime: 1447805278.124815] Rapp Manager : 'rocon_apps/lion_chirp' is invalid [operating_system specification is invalid or not officially registered (see https://github.com/robotics-in-concert/rocon_tools/blob/indigo/rocon_uri/src/rocon_uri/rules/rules.yaml)[vivid]]

This file only seems that it can get out of date? Why reproduce the data here?

Short term, I've added the operating system to the rules.

Long term an agnostic rapp like chirp shouldn't care about the operating system underneath. I think this has been fixed in our recent branch, but I'll leave this open here till I confirm.

Yes, it can get out of date. If I recall, this was so validition at various levels could be tighter than just string matching any pair of strings at runtime (e.g. vivix would get caught as an error earlier in development rather than at runtime later when failing against an os with vivid). Tradeoff of course is it needs more maintenance. If I did this again, I'd be more inclined to avoid the maintenance, as I see you are.

What did you mean by reproduce? Is it getting produced elsewhere?

[tfoote]

I meant reproduce the list of possible os's to validate against. You can probably pull it in from rospkg. https://github.com/ros-infrastructure/rospkg/blob/master/src/rospkg/os_detect.py

Ah, got it. Tasks for this issue:

• rapps with no dependencies should be agnostic about a missing operating system match.
• operating system list should at least be initialised from rospkg
