[JBoss JIRA] Created: (ISPN-318) Locking could optionally be "fair"

by Manik Surtani (JIRA)

Locking could optionally be "fair" ---------------------------------- Key: ISPN-318 URL: https://jira.jboss.org/jira/browse/ISPN-318 Project: Infinispan Issue Type: Feature Request Components: Locking and Concurrency Affects Versions: 4.0.0.CR3 Reporter: Manik Surtani Assignee: Manik Surtani Fix For: 4.0.0.GA Would require a number of changes: 1. A new boolean field and getter/setter in Configuration.LockingType (follow patterns of other boolean flags here to ensure proper XSD and parser generation), perhaps called "useFairLocking", defaults to false. 2. Modify LockManagerImpl to pass this flag into the LockContainer implementations (in LockManagerImpl#startLockManager()) 3. Modify the 4 concrete LockContainer implementations to use this flag when creating new locks. Implementations that use JDK reentrant locks just need to pass the fairness flag into the ReentrantLock constructor. 4. Modify OwnableReentrantLock to handle fairness. Referring to the JDK's ReentrantLock.FairSync may help. OwnableReentrantLock combines features of the JDK ReentrantLock and ReentrantLock.NonFairSync into a single class, so perhaps the best approach is to create a new OwnableFairReentrantLock. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Updated: (ISPN-58) Create a TaskQueueExecutorFactory and TaskQueueScheduledExecutorFactory

by Manik Surtani (JIRA)

[ https://jira.jboss.org/jira/browse/ISPN-58?page=com.atlassian.jira.plugin... ] Manik Surtani updated ISPN-58: ------------------------------ Fix Version/s: 5.0.0.BETA1 5.0.0.GA (was: 4.1.0.BETA1) (was: 4.1.0.GA) > Create a TaskQueueExecutorFactory and TaskQueueScheduledExecutorFactory > ----------------------------------------------------------------------- > > Key: ISPN-58 > URL: https://jira.jboss.org/jira/browse/ISPN-58 > Project: Infinispan > Issue Type: Sub-task > Reporter: Manik Surtani > Assignee: Manik Surtani > Fix For: 5.0.0.BETA1, 5.0.0.GA > > > These executors will not spawn separate threads, but hook in to Google's TaskQueue API > http://code.google.com/appengine/docs/java/taskqueue/overview.html > This will enable Infinispan to run without spawning any additional threads, thereby enabling it to run on Google's App Engine runtime. > Will need to expose a URI (/taskqueueexecutor ?) which is invoked to process arbitrary Callable/Runnables. May need to use the DataStore to store the actual Callable/Runnable, and pass the taskqueueexecutor the key of the stored object. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Updated: (ISPN-57) Support Google App Engine

by Manik Surtani (JIRA)

[ https://jira.jboss.org/jira/browse/ISPN-57?page=com.atlassian.jira.plugin... ] Manik Surtani updated ISPN-57: ------------------------------ Fix Version/s: 5.0.0.BETA1 5.0.0.GA (was: 4.1.0.GA) (was: 4.1.0.BETA1) > Support Google App Engine > ------------------------- > > Key: ISPN-57 > URL: https://jira.jboss.org/jira/browse/ISPN-57 > Project: Infinispan > Issue Type: Feature Request > Components: Core API > Reporter: Adrian Cole > Assignee: Manik Surtani > Fix For: 5.0.0.BETA1, 5.0.0.GA > > > Google App Engine for Java is a restricted JVM. It prevents such things as file access and thread creation. Currently, Infinispan requires at least thread creation and depending on the cachestore mechanism, potentially file as well. > This is a container to investigate other related issues that may prevent Infinispan from running on GAE. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Updated: (ISPN-3) Should use JGroups scoping

by Manik Surtani (JIRA)

[ https://jira.jboss.org/jira/browse/ISPN-3?page=com.atlassian.jira.plugin.... ] Manik Surtani updated ISPN-3: ----------------------------- Fix Version/s: 5.0.0.BETA1 5.0.0.GA (was: 4.1.0.BETA1) (was: 4.1.0.GA) > Should use JGroups scoping > -------------------------- > > Key: ISPN-3 > URL: https://jira.jboss.org/jira/browse/ISPN-3 > Project: Infinispan > Issue Type: Feature Request > Components: RPC > Reporter: Manik Surtani > Assignee: Vladimir Blagojevic > Fix For: 5.0.0.BETA1, 5.0.0.GA > > > JGroups will provide a scoping API. This allows better concurrency in the JGroups channel. By default, the scope used should be the cache name, although use of other scopes should be allowed such as GlobalTransaction. Also need to consider allowing arbitrary scopes, passed in by user code. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
