Class PlanExecutionManagerImpl

java.lang.Object
com.atlassian.bamboo.plan.PlanExecutionManagerImpl
All Implemented Interfaces:
ExecutionStatusProvider, PlanExecutionManager
public class PlanExecutionManagerImpl extends Object implements PlanExecutionManager
We have 3 (yes, three) ways to handle BuildDetectionAction, it all depends which interface is implemented:
  1. UnconditionalBuildDetectionAction - meaning: if this action is created we know we want to start a build. (example: scheduled build, dependant build...)
  2. DelayedChangeDetectionAction - special case of 1) with added feature of calling thread not being blocked by change detection (manual builds, restarted builds...)
  3. ConditionalBuildDetectionAction - we don't know a priori if we want to start a build (trigger by vcs change)
How do we handle each case (pseudocode): 
  1.  inChangeDetectionLock
 {
 inBuildCountLock
 {
 checkIfCountNotExceeded
 createResultWithoutChanges
 }
 doChangeDetection
 }
 
  2.  inBuildCountLock
 {
 checkIfCountNotExceeded
 createResultWithoutChanges;
 inNewThread
 {
 inChangeDetectionLock
 {
 doChangeDetection
 }
 }
 }
 
  3.  inChangeDetectionLock
 {
 inBuildCountLock
 {
 checkIfCountNotExceeded
 }
 doChangeDetection
 inBuildCountLock
 {
 checkIfCountNotExceeded
 createResultWithChanges
 }
 }
