[JBoss JIRA] Created: (ISPN-439) Define and implement configuration file backward and forward compatibility policy

by Vladimir Blagojevic (JIRA)

Define and implement configuration file backward and forward compatibility policy --------------------------------------------------------------------------------- Key: ISPN-439 URL: https://jira.jboss.org/jira/browse/ISPN-439 Project: Infinispan Issue Type: Task Affects Versions: 4.1.0.BETA1 Reporter: Vladimir Blagojevic Assignee: Manik Surtani Fix For: 4.1.0.CR1 Backward compatibility: Process any previous version configuration file from the same minor version. For example, Infinispan release 4.2 should process configuration file produced for version 4.1 without any configuration file changes or any other adjustments. For configuration options present in 4.2, but not in 4.1 assume default values. However, Infinispan version 5.0 is not required to process configuration files from previous major versions, i.e 4.0...4.x. Forward compatibility. Do not process any forward version configuration file. For example, Infinispan release 4.1, give configuration file input from any succeeding versions (i.e 4.2...4.x, 5.x) would simply fail outright with proper error message. -- 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-658) DistributionManager not considerate of cache state changes

by Paul Ferraro (JIRA)

DistributionManager not considerate of cache state changes ---------------------------------------------------------- Key: ISPN-658 URL: https://jira.jboss.org/browse/ISPN-658 Project: Infinispan Issue Type: Bug Components: Distributed Cache Affects Versions: 4.2.0.ALPHA2 Reporter: Paul Ferraro Assignee: Manik Surtani Considering a cache manager with 2 caches in DIST mode (C1 and C2) deployed on 2 nodes (N1 and N2). Currently, the DistributionManager does not properly handle the following scenarios: 1. Stop C1 on N1. This ought to trigger a rehash for the C1 cache. Currently, rehashing is only triggered via view change. Failure to rehash on stopping of a cache can inadvertently cause data loss, if all backups of a given cache entry have stopped. 2. A new DIST mode cache, C3, is started on N2. If N1 is the coordinator, the join request sent to N1 will get stuck in an infinite loop, since the cache manager on N1 does not contain a C3 cache. 3. Less critically, a new node, N3 is started. It does not yet have a C1 or C2 cache, though it's cache manager is started. This prematurely triggers a rehash of C1 and C2, even though there are no new caches instances to consider. -- 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-434) Creating a new distributed cache on a non-coordinator node causes rehashing to hang

by Manik Surtani (JIRA)

Creating a new distributed cache on a non-coordinator node causes rehashing to hang ----------------------------------------------------------------------------------- Key: ISPN-434 URL: https://jira.jboss.org/jira/browse/ISPN-434 Project: Infinispan Issue Type: Bug Components: Distributed Cache Affects Versions: 4.1.0.ALPHA3 Reporter: Manik Surtani Assignee: Manik Surtani Fix For: 4.1.0.CR1, 4.1.0.Final If a cluster is already formed (perhaps due to another cache instance being started, such as a replicated one) and subsequently a distributed cache is created and started, first on a non-coordinator node, the startup sequence will hang until the cache is also started on the coordinator. E.g., 1. C1 (coord) starts replicated cache 2. C2 starts replicated cache 3. C2 starts distributed cache 4. C1 starts distributed cache Step 3 will hang until step 4 completes. So unless these happen in different threads - on different servers - this rehash will hang. -- 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-448) Consider all topology cache updates to be done by coordinator in Hot Rod

by Galder Zamarreno (JIRA)

Consider all topology cache updates to be done by coordinator in Hot Rod ------------------------------------------------------------------------ Key: ISPN-448 URL: https://jira.jboss.org/browse/ISPN-448 Project: Infinispan Issue Type: Task Components: Cache Server Reporter: Galder Zamarreno Assignee: Galder Zamarreno Fix For: 5.0.0.BETA1 Based on the discussion below, consider all topology cache updates to be done by coordinator to avoid concurrency issues when updating it. > Looks good. > What is causing this unsuccessful add? If it is caused by timeouts due > to multiple caches operating on the same key an alternative would be > to only perform the operation on the coordinator and rest of the > members to have node added listeners ... Currently, each node when it starts, it's responsible of adding itself to the view and when it stops, it's responsible from removing itself. Apart from this, there's a crashed member listener running only in coordinator that detects whether any member left without updating the topology view. Your suggestion to have the coordinator control it all seems like could work and get around potential timeouts. I'll create a JIRA to investigate this but won't do it for CR1 since I'm expect this to be a major issue. Metadata size is small and it's not constantly uddated. -- 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-302) Enable templated values for manually adding instances via jopr

Enable templated values for manually adding instances via jopr -------------------------------------------------------------- Key: ISPN-302 URL: https://jira.jboss.org/jira/browse/ISPN-302 Project: Infinispan Issue Type: Feature Request Components: JMX, reporting and management Reporter: Galder Zamarreno Assignee: Galder Zamarreno Fix For: 4.1.0.BETA1 Enable templated values for manually adding instances via jopr >> For manually importing - you should in the plugin descriptor put the JMX-remoting url as >> >> default -- perhaps with the port as XXX, so the user does not have to copy& paste from an >> >> external location, but only click in the text field and replace XXX by the real port. >> >> same for Objectname of the cache manager. > > > > I did that. I told you it did not work and your reply was that it was fragile and you didn't looked into it further... You / we were talking about c:template - which would allow to have several templates -- see jmx-plugin e.g http://git.fedorahosted.org/git/rhq/rht.git?p=rhq/rhq.git;a=blob;f=module... from line 47 on What you can do, an which works is <c:simple-property name="v1Community" type="string" default="public"/> Here the default value 'public' is shown to the user for this property.

[JBoss JIRA] Created: (ISPN-200) Distributed queries

by Manik Surtani (JIRA)

Distributed queries ------------------- Key: ISPN-200 URL: https://jira.jboss.org/jira/browse/ISPN-200 Project: Infinispan Issue Type: Feature Request Components: Distributed Cache, Querying Reporter: Manik Surtani Assignee: Manik Surtani Fix For: 5.1.0.BETA1, 5.1.0.GA The holy grail of querying. * Indexes are _never_ shared. * Each node maintains local indexes for state it is responsible for (-Dinfinispan.query.indexLocalOnly=true). * Indexes could be in memory or disk. * Queries themselves are distributed. * The query object is built and broadcast to the entire cluster. * Each node executes the query on its own _local_ index, returning results. * The calling node returns a CacheQuery impl that lazily fetches and collates results from the cluster. * I expect this Map/Reduce model to perform very well since the workload is split up and happens in parallel across multiple CPUs against much smaller (individual) datasets. * Works with all cache modes, including DIST. * Need to make sure duplicates are handled, as well as failover. -- 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-575) Corruption in data when using a permanent store between stop-start cycles

by Sanne Grinovero (JIRA)

Corruption in data when using a permanent store between stop-start cycles ------------------------------------------------------------------------- Key: ISPN-575 URL: https://jira.jboss.org/browse/ISPN-575 Project: Infinispan Issue Type: Bug Components: Loaders and Stores Affects Versions: 4.1.0.CR2 Reporter: Sanne Grinovero Assignee: Manik Surtani Fix For: 4.1.0.Final We verified the issue while using the Lucene Directory; using the Directory under stress leads to no issues even during long running tests of several hours. If during the same stress test a permanent store is enabled, all works still fine, until the CacheManager is stopped. No errors during the stop(), but after starting it again the checksum on some data fails and the index is unusable. -- 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-230) Enable JNDI binding of Cache/CacheManager out of the box

by Galder Zamarreno (JIRA)

Enable JNDI binding of Cache/CacheManager out of the box -------------------------------------------------------- Key: ISPN-230 URL: https://jira.jboss.org/jira/browse/ISPN-230 Project: Infinispan Issue Type: Feature Request Reporter: Galder Zamarreno Priority: Minor Fix For: 4.1.0.BETA1 Note that implementing this has no urgency since it does not really help Brian S for the JBoss AS integration. See: http://lists.jboss.org/pipermail/infinispan-dev/2009-October/001663.html So, I'm thinking that we could have a <jndi name="xyz"/> configuration option both at the global level (for Cache Manager) and at the Cache level. So, - if <jndi/> was present in the global section, we'd bind CacheManager to java:CacheManager - if <jndi name="xyz"/> was present in the global section, we'd bind CacheManager to java:xyz - if <jndi/> was present in the cache section, we'd bind Cache to java:<name-of-the-cache> - if <jndi name="xyz"/> was present in the cache section, we'd bind Cache to java:xyz -- 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
