436213 - ensure talos tests all builds through disallowing buildbot from combining build requests

Status: RESOLVED WORKSFORME

(Release Engineering :: General, defect, P3)

Description

[alice nodelman [:alice] [:anode]]

When requests for talos to test start to back up buildbot starts collapsing separate pending requests into one monolithic request.  We want to keep all requests unique so that we test all builds.

We may have to consider specifically not testing all builds if we find that we get too backed up - but we can consider that once we have a better idea what the real load on the machines will be.

This class blocks the builds from merging

I filed http://buildbot.net/trac/ticket/288, too. Would that be of interest?

Tests of this scheme on talos stage showed really bad situations where builds would back up in the hundreds on single slave factories.  We're happy to live with the merging for now and deal with this in the future by increasing the number of available slaves for testing.
