Re: [infinispan-dev] Command cancellation

Hi, I wanted to run by you guys design of command cancellation Manik and I talked about recently. For more background regarding this task read https://issues.jboss.org/browse/ISPN-1042 At originating node I would have each Cancellable command create its UUID as part of constructor. After that command gets sent away to remote VMs but just before it gets executed there we associated thread with UUID by calling CancellationService.registerThread (as a first line of code in Command#perform). After registration has been setup Cancellable command goes into potentially lengthy (in seconds) execution. If needed we would be able to send CancelCommand which would call CancellationService#cancelTask with UUID. CancelTask would interrupt the associated thread. WDYT? Regards, Vladimir Cancellation of tasks: class CancellationService { UUID registerThread(Thread t, UUID uuid) { // put thread in map, associate with newly give UUID } void cancelTask(UUID uuid) { // look up thread, interrupt if exists. } } interface CancellableCommand { UUID getCommandUUID(); } command CancelCommand { Object perform() { // Calls CancellationService.cancelTask with UUID. The UUID is a parameter of this command. } } _______________________________________________ infinispan-dev mailing list infinispan-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/infinispan-dev
