teuthology job priorities

Hi,

This morning I'll schedule a job with priority 50, assuming nobody will get mad at me for using such a low priority because the associated bug fix blocks the release of v0.94.2 (http://tracker.ceph.com/issues/11546) and also assuming noone uses a priority lower than 100 just to get in front of the nightlies[1]. In my imagination

   priority [0,100] is for emergencies
   priority [100,1000] is to schedule a job with higher priority than the nightlies
   priority 1000 (the default) is for all automated tests and no human being wait on them (the nightlies for instance).

Does someone have a different mapping in mind ?

Cheers

I usually use: 
priority [90,100]

for point releases validations.

This is a good thread to bring up for open approval/disapproval.

Does that sound reasonable ??

Thx

Those are pretty sensible. In practice I think the important points to
be aware of are:
1000: nightly priority
101: Sam's priority for anything he schedules.

That 101 can be a bit tricky since going over it can mean you don't
run for a few days if he's busy running stuff repeatedly. It's kind of
an unfortunate race to the bottom when there are several people who
think their stuff is important. (A few weeks ago Sage was running RGW
bugfix tests for several days, at least some of which were priority 1.
I was also trying to push some stuff through at the time and that was
quite an experience.) :/
