[users at bb.net] Triggered builds getting skipped

[Pierre Tardy]

Interrestingly, I see a lot of buildrequests that are indeed claimed,
complete and with "SKIPPED" (code 6) results.
They are finished 7 seconds after being claimed.
That would be interresting to also see the list of builds, to see if there
is a corresponding SKIPPED build.

I did a quick search for SKIPPED in the source code, and see that a
buildrequests can be marked SKIPPED by the build request collapser:

    # Before adding new buildset/buildrequests, we must examine each
unclaimed
    # buildrequest.
    # EG:
    #  1. get the list of all unclaimed buildrequests:
    #     - We must exclude all buildsets which have at least 1 claimed
buildrequest
    #  2. For each unclaimed buildrequests, if compatible with the new
request
    #     (sourcestamps match, except for revision) Then:
    #     2.1. claim it
    #     2.2. complete it with result SKIPPED

This can explain that the more you have, and the more it skips.

You may want to force collapseRequests=False in your triggered builder
configuration.
