[ros-release] Fwd: Torrents of Emails

[Tully Foote]

Preventing email overload is definitely something we work hard to avoid. We
know that if there are too many false positives people will simply ignore
them.

And we shutdown the farm as soon as we diagnosed the issue:
http://status.ros.org/  Unfortunately when you run a very parallelized
system if there's a systematic failure, such as the code hosting going
down, a lot of jobs fail quickly.

One thing from travis testing Travis distinguishes between build/test
errors vs configuration errors. There's a ticket open to add this
enhancement https://github.com/ros-infrastructure/buildfarm/issues/116 but
unfortunately this is not something that Jenkins differentiates so it will
take a lot of doing to make this happen on top. An approach I could see for
this is to customize the emailing plugin and be able to pass it flags
earlier in the process confirm that the configuration and setup has
completed successfully. And likewise the actual results should be shown the
same way too with the job aborting instead of failing when the
configuration/setup phase fails.
