        Description copied from interface: QueueOfExecutables
        Called when a given executable is en route to agent. May be implemented as a simple remove(). Executables in flight should be treated as removed, but may be put back into a queue if an agent fails to acknolwedge that it received the executable.
        Specified by:
        inflight in interface QueueOfExecutables
        Returns:
        the removed context

        Parameters:
        context - context to enqueue
        requirements - requirements needed to execute the context, may be null
        Returns:
        FAILED if requirements could not be retrieved for a build and were not provided in the call (assumption: the reason is that the build got deleted) ENQUEUED_COMMON if successfully enqueued ENQUEUED_DEDICATED if successfully enqueued and requested a dedicated agent for the execution
      • recalculateExecutors

        public void recalculateExecutors()
        Description copied from interface: QueueOfExecutables
        Recalculates executors for all executables - until then, any information about executor-executable mapping should be considered to be invalid. The dedicated agents won't be launched as a part of this process.
        Specified by:
        recalculateExecutors in interface QueueOfExecutables
      • size

        public int size()
        Description copied from interface: QueueOfExecutables
        Returns the amount of executables in queue (not counting executables in flight)
        Specified by:

      • getNonDedicatedImagesForExecutable

        @Nullable
        public @Nullable Collection<ElasticImageConfiguration> getNonDedicatedImagesForExecutable​(@NotNull

        Description copied from interface: QueueOfExecutables
        Returns the images that can execute the given executable. If the executable is not found, null is returned. If the executable is dedicated at the moment of check, the empty list will be returned.
        Specified by:
        getNonDedicatedImagesForExecutable in interface QueueOfExecutables
        Parameters:
        resultKey - executable
        Returns:
        list of elastic image configurations

                                                                                      @NotNull ResultKey resultKey)
        Description copied from interface: QueueOfExecutables
        Returns the ephemeral agents templates currently considered to be eligible for building resultKey. If the resultKey is not found the null is returned.

      • removeDedicationTimestamp

        public void removeDedicationTimestamp​(@NotNull
                                              @NotNull ResultKey resultKey)
        Description copied from interface: QueueOfExecutables
        Remove the dedication timestamp for the given result key if the one exists. The dedication timestamp works as a due-to-date, to which the build queue holds the related executable for a dedicated agent. After the date pass, every executor can grab the executable. Removing the dedication timestamp means that the executable is no longer dedicated.
        Specified by:
        removeDedicationTimestamp in interface QueueOfExecutables
        Parameters:
        resultKey - of the related executable

        Description copied from interface: QueueOfExecutables
        Recalculates executors for a given plan - until then, any information about executor-executable mapping for this plan should be considered to be invalid.
        Specified by:
        recalculateExecutors in interface QueueOfExecutables
        Parameters:
        keys - the keys to invalidate

        Description copied from interface: QueueOfExecutables
        Launches dedicated agents for the given template and executables present in the queue at the moment of this method call. The dedicated agent will be launched if the corresponding executable is not already waiting for any dedicated agent.
        Specified by:
        launchDedicatedAgentsForTemplate in interface QueueOfExecutables
        Parameters:
        template - the template to launch dedicated agents for
