Buildbot has too many pending jobs and has stopped building at all

Question

I encountered a problem in which buildbot has too many pending jobs and has stopped doing any more builds. Even when I restart the buildbot, the pending jobs do not go away. I want to be able to do the build and remove the pending jobs. How can i do that?

Answer 1

To be able to cancel pending builds you must have this feature enabled in the authz.Authz setting in the master.cfg file of your buildmaster,e.g.

authz_cfg=authz.Authz(
    # change any of these to True to enable; see the manual for more
    # options
    gracefulShutdown = False,
    forceBuild = True,
    forceAllBuilds = False,
    pingBuilder = False,
    stopBuild = True,
    stopAllBuilds = False,
    cancelPendingBuild = True,
)

Documentation here

Once you've done that you'll need to restart your buildmaster. Then, on the web-status page of any builder, you'll see buttons to cancel any pending builds as well as the running build.
