Description Sascha Silbe 2009-08-09 12:40:51 UTC 
Most of our build slaves are currently VMs on the same physical host. Because JHBuild uses the "Periodic" scheduler and starts it immediately on startup, all builds will run in parallel, causing high load every 12 hours and no load in between.
It would be great if the the scheduler options were configurable per slave (and the scheduler itself globally) so we can tune the start times to cater for our special situation.

I finally had time to work on this, sorry for taking so long.

    [builbot] add support for the nightly scheduler (GNOME bug 591231)
    
    A slave can be set to use that scheduler from its configuration file, from
    /config/scheduler:
      <config>
        <scheduler>nightly</scheduler>
      </config>
    
    And there is support for all buildbot nightly scheduler keywords (minute,
    hour, dayOfWeek, month, dayOfMonth); to get a build started every xx:06:
      <nightly_scheduler>
        <minute>6</minute>
      </nightly_scheduler>

Great news, thanks!
Comment 3 Sascha Silbe 2010-01-06 21:02:17 UTC 
We don't have any XML configuration files for (sugar-)jhbuild and/or BuildBot yet. Where do I need to put those lines? I didn't find anything documentation (neither did I find any mention of the slaves.csv stuff). :-/
Comment 4 Frederic Peters 2010-01-06 21:27:48 UTC 
I started documenting the buildbot stuff, but stopped at the slave part :/

If you have a slave named foobar, mentioned in your slaves.csv, you'd create a foobar.xml in the same directory, with such a content:

<botslave>
  <config>
    <max_builds>2</max_builds>
    <run_checks>yes</run_checks>
    <scheduler>nightly</scheduler>
  </config>
  <nightly_scheduler>
    <minute>6</minute>
  </nightly_scheduler>

It was a bumpy ride, but now it works, thanks! Will file tickets about the two issues encountered.
