operation status

removeBuildFromQueue

public CommonContext removeBuildFromQueue(@NotNull

Description copied from interface: BuildQueueManager

Removes the CommonContext associated with the resultKey to be removed from the queue.

@Nullable
public @Nullable Collection<ElasticImageConfiguration> getImagesForQueuedExecutable(@NotNull
 @NotNull ResultKey resultKey)

Specified by:

Returns:

the images that can execute the given executable. returns null if the executable is unknown.

getNonDedicatedImagesForQueuedExecutable

@Nullable
public @Nullable Collection<ElasticImageConfiguration> getNonDedicatedImagesForQueuedExecutable(@NotNull
 @NotNull ResultKey resultKey)

Description copied from interface: BuildQueueManager

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:

getNonDedicatedImagesForQueuedExecutable in interface BuildQueueManager

Parameters:

resultKey - executable

Returns:

list of elastic image configurations

getTemplatesForQueueExecutable

@Nullable
public @Nullable Collection<EphemeralAgentTemplate> getTemplatesForQueueExecutable(@NotNull
 @NotNull ResultKey resultKey)

Description copied from interface: BuildQueueManager

Returns the ephemeral agents templates currently considered to be eligible for building resultKey. If the resultKey is not found the null is returned.

Specified by:

getTemplatesForQueueExecutable in interface BuildQueueManager

Parameters:

resultKey - result key to look for

Returns:

getExecutorsForQueuedExecutable

@Nullable
public @Nullable Set<Long> getExecutorsForQueuedExecutable(@NotNull
 @NotNull ResultKey resultKey)

Specified by:

getExecutorsForQueuedExecutable in interface BuildQueueManager

Returns:

the ids of agents that can execute the given executable. returns null if the executable is unknown.

peekContext

@Nullable
public @Nullable BuildQueueManager.QueueItemView<CommonContext> peekContext(@NotNull
 @NotNull ResultKey resultKey)

Description copied from interface: BuildQueueManager

Returns a queued CommonContext for given resultKey. Consider using com.atlassian.bamboo.v2.build.queue.QueueManagerView for your build queue viewing needs}

public void restoreState(Set<ResultKey> resultsToRestore)

Description copied from interface: BuildQueueManager

Restore state after server restart.

Specified by:

restoreState in interface BuildQueueManager

removeDedicationTimestamp

public void removeDedicationTimestamp(@NotNull
 @NotNull ResultKey resultKey)

Description copied from interface: BuildQueueManager

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 BuildQueueManager

Specified by:

takeBuildContext in interface AgentQueueAccessor

Parameters:

agentId - the id of the agent that is taking the build context.

Returns:

The CommonContext, null in case of timeout on retrieval.

Description copied from interface: AgentQueueAccessor

Takes a CommonContext from the queue, blocking until one is available.

The lock on the build is not released. The caller should call com.atlassian.bamboo.build.BuildExecutionManager#finishBuild(PlanResultKey) to release this lock when ready.

Specified by:

takeContext in interface AgentQueueAccessor

Parameters:

agentId - the id of the agent that is taking the build context.

Returns:

The AgentQueueAccessor.QueueAccessResult containing: CommonContext on success, error message on error, nulls in case of timeout on retrieval.

Throws:

InterruptedException - if the calling Thread is interrupted.

takeContext

public AgentQueueAccessor.QueueAccessResult takeContext(long agentId,
 @Nullable
 @Nullable ResultKey resultKey)
                                                 throws InterruptedException

Description copied from interface: AgentQueueAccessor

If resultKey is not null, takes a specific CommonContext from the queue or nothing if there's no job with specified key in the queue. If resultKey is null, behaved identically to AgentQueueAccessor.takeContext(long).

The lock on the build is not released. The caller should call com.atlassian.bamboo.build.BuildExecutionManager#finishBuild(PlanResultKey) to release this lock when ready.

takeContext in interface AgentQueueAccessor

Parameters:

agentId - the id of the agent that is taking the build context.

resultKey - of the job that agent expects to receive
