[JBoss JIRA] (ISPN-6745) Locks are lost in pessimistic cache
by Eugene Scripnik (JIRA)
[ https://issues.jboss.org/browse/ISPN-6745?page=com.atlassian.jira.plugin.... ]
Eugene Scripnik updated ISPN-6745:
----------------------------------
Description:
When you perform multiple TX write operations in one transaction (put, replace, lock, etc) and one of the nodes goes down, there is a slight chance that some locks will be lost and acquired by another transaction before current transaction ends.
So client ends up with two transactions holding the same lock on pessimistic cache at the same time. Both transactions commit at the end successfully.
I spent some time debugging infinispan code and found that PessimisticLockingInterceptor#releaseLocksOnFailureBeforePrepare releases all locks when OutdatedTopologyException occurs on remote node. But then StateTransferInterceptor#handleTxWriteCommand retries last command. This behavior produces inconsistent state - all locks before last command are released and any other transaction can acquire them.
I am attaching Test which reproduces this problem

Summary: ClusterEvent doesn't implement CacheEntryExpired

Project: Infinispan
Issue Type: Bug
Components: Expiration, Listeners
Reporter: William Burns

Fix For: 9.0.0.Alpha3
ClusterEvent needs to implement CacheEntryExpired or else it cannot be replicated as a cluster event in the event of an expiration not on a node where a cluster listener was registered.

[JBoss JIRA] (ISPN-6743) Upsert does not work for MySQL

Krzysztof Sobolewski updated ISPN-6743:
---------------------------------------
Description:
ISPN-20, merged recently (thanks!), added "upsert" support for JDBC cache stores. The "upsert" SQL statement is database-type-dependent and the one for MySQL has a different "API" than the one for other database types - whereas all the others use the same number and order of placeholders as the equvalent INSERT statement, so that the same method can be used to update the INSERT, UPDATE and "upsert" statement, the MySQL one adds additional placeholders and the aforementioned method is no longer sufficient.
The exception is:
java.sql.SQLException: No value specified for parameter 4

> If there's no further view changes, the topology ID will remain 0. When a Hot Rod client first connects, it sends its view topology as 0 so that it receives a newly installed topology, but if the topology is already 0 in the server, the server won't send the installed topology, even though it should be newer than having no topology.
> We should start numbering topologies in server starting from 1 instead. That avoids this issue. This is easier than forcing clients to send -1 as initial topology because the topology ID is currently defined as VInt that can only 0 or positive number.
> Also, some extra log messages indicating that the cache topology installed comes from persisted state would be handy for debugging.
