[lldb-dev] [zorg] r214540 - Fixed mergefunc builder configure; added lldb builder for FreeBSD.

[Galina Kistanova]

Hi Vince,

Maybe "experimental" is not the best word to name the group. Anyway, the
actual meaning is a group of builders which does not send e-mail
notifications to the blame list on a failure after a green or interrupted
build.
These builders are shown in the UI as usual, though, on the waterfall page
they are at the right. The IRC notifications are sent on every builder
status change.
The builders of this group builds on demand only.
I think this is not a desired behavior in this case. We still want these
builders to build on regular commits to the dependent projects, I guess.
This is an easy change. I'll make it as well.
Originally, the purpose of this group is just like that - someone introduce
a new builder, work out all possible issues and make it reliably green,
before it gets to a pool of regular builders and gets noisy.
The major issue with an unreliable builder is people get annoyed and stop
pay attention to the failures. It would take quite an effort to get the
situation back to normal.

Thanks


Galina
