<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">So as a test I created a nextSlave function to allow a job only if the slave is idle. It sort of works except when getNext is called back to back. In that case
I get two builds scheduled on one machine when there should only be one. It looks like the builder’s current builds hasn’t had time to be updated. Is there a lock I could use? Or a pending builds list somewhere?<o:p></o:p></span></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">Is there a way to limit the number of builds per node for a set of builders? I’m using a slave lock for that purpose on the builder and it’s not quite what I’d like to happen. The
builds start on a specific slave in the starting state. But they’re waiting not starting and it makes it difficult in the UI to see what is currently running. Also I’d rather the scheduling be performed dynamically at the time slaves become free. Is there
another way to do this? <o:p></o:p></p>
