[JBoss JIRA] Created: (ISPN-303) Follow up Jopr demo ideas

by Galder Zamarreno (JIRA)

Follow up Jopr demo ideas ------------------------- Key: ISPN-303 URL: https://jira.jboss.org/jira/browse/ISPN-303 Project: Infinispan Issue Type: Task Components: JMX, reporting and management Reporter: Galder Zamarreno Assignee: Galder Zamarreno Fix For: 4.1.0.BETA1 Ideas for a follow up Jopr demo: - Show ISPN-302 in action. - Heiko: About the monitoring schedules : in Administration->System Configuration->Templates you can also "predefine" this, so it gets applied to every new instance (and if wanted also to all existing instances). - Heiko: mention that 30 seconds is too too short for production -- 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] Created: (ISPN-586) ManagedConnectionPool doesn't work in a transactional context

by Manik Surtani (JIRA)

ManagedConnectionPool doesn't work in a transactional context ------------------------------------------------------------- Key: ISPN-586 URL: https://jira.jboss.org/browse/ISPN-586 Project: Infinispan Issue Type: Bug Components: Loaders and Stores, Transactions Affects Versions: 4.1.0.CR2 Reporter: Manik Surtani Assignee: Manik Surtani Fix For: 4.1.0.CR3 >From the reporter: "Anyways, what seems to be the real problem is that all the things that need to be persisted are saved in memory and then when the transaction is completing (either in prepare or commit phase) the loader attempts to get a connection from the datasource. Apparently this is illegal and throws an exception which is what causes the HeuristicMixedException further up the chain. This only fails when using a ManagedConnectionFactory. If I swap out a PooledConnectionFactory it works fine. I presume the managed version fails because it returns the same connection that is part of the active transaction for that thread and you can't perform new operations on that connection once the transaction is already in prepare or commit. This feels like a bit of a design flaw to me... I didn't see an obvious fix." This possibly has to do with the AbstractCacheStore doing the following in prepare(): " public void prepare(List<? extends Modification> mods, GlobalTransaction tx, boolean isOnePhase) throws CacheLoaderException { if (isOnePhase) { applyModifications(mods); } else { transactions.put(tx, mods); } } " and later during commit actually writing the changes to the store. This generic, "abstract" behaviour is intended for non-transactional data stores (such as a filesystem). Behaviour should be different when it comes to transactional data stores. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

FIFO queu support ----------------- Key: ISPN-132 URL: https://jira.jboss.org/jira/browse/ISPN-132 Project: Infinispan Issue Type: Feature Request Components: Core API Reporter: Bryan Grunow Assignee: Manik Surtani Add support for retrieving entries from the cache via insertion (FIFO) order. For example, cache.getNext(); would return the next entry in the queue. -- 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] Created: (ISPN-492) Use map implementations that do array equality based on contents

by Galder Zamarreno (JIRA)

Use map implementations that do array equality based on contents ---------------------------------------------------------------- Key: ISPN-492 URL: https://jira.jboss.org/browse/ISPN-492 Project: Infinispan Issue Type: Feature Request Reporter: Galder Zamarreno Assignee: Manik Surtani Make Infinispan use backing maps that do array equality based on its contents and not on reference. This would for example allow us to have maps with byte[] as keys without the need of wrapping these arrays into something else. This would need subclassing or reimplementing maps to make comparisons based on contents. An config option could be added if someone needed standard JDK map behavior. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (ISPN-484) Querying over HotRod

by Galder Zamarreno (JIRA)

Querying over HotRod -------------------- Key: ISPN-484 URL: https://jira.jboss.org/browse/ISPN-484 Project: Infinispan Issue Type: Feature Request Components: Cache Server, Querying Reporter: Galder Zamarreno Assignee: Galder Zamarreno Fix For: 5.1.0.Final Investigate how to allow Hot Rod servers to be queries, particularly since server stores key/values in serialized byte arrays. Also, look into how to improve the protocol to potentially allow remote querying. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (ISPN-144) graph based deadlock detection

by Mircea Markus (JIRA)

graph based deadlock detection ------------------------------- Key: ISPN-144 URL: https://jira.jboss.org/jira/browse/ISPN-144 Project: Infinispan Issue Type: Feature Request Reporter: Mircea Markus Assignee: Manik Surtani Fix For: 4.1.0.GA current deadlock detection impl only knows to look for deadlocks between two transactions: i.e. tx1 (k1,k2) tx (k2,k1). This might be enhanced with transitive deadlock detection check: tx1(k1,k2) tx2(k2,k3) tx3(k3,k1). In the previous example, if all transactions are done acquiring first lock we result in a deadlock. Needs further thinking. -- 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
