[JBoss JIRA] Created: (ISPN-825) Consider staggering remote get requests when using DIST

by Manik Surtani (JIRA)

Consider staggering remote get requests when using DIST ------------------------------------------------------- Key: ISPN-825 URL: https://jira.jboss.org/browse/ISPN-825 Project: Infinispan Issue Type: Feature Request Components: RPC Affects Versions: 4.1.0.Final Reporter: Manik Surtani Assignee: Manik Surtani Fix For: 5.0.0.BETA1, 5.0.0.Final In DIST mode, when a request is made on a key that is not mapped locally, a remote get is sent to all data owners of that key and the first response is used. This can add unnecessary load on the network as all nodes still eventually respond, and if values are large this can cause a lot of unnecessary network traffic. The purpose of broadcasting to all data owners is so that (1) if one is down, another could still respond (2) if one is overloaded, others may respond faster. A solution around this could be based on either (or both) of: * Provide a configurable stagger timeout, e.g. 100ms. E.g., RPC to (random) Owner1. Wait for timeout t. If no response, RPC to Owner2. etc. * Always broadcast to a (configurable) subset of owners, e.g., always 2 even if numOwners is 5. Needs careful thought and design. -- This message is automatically generated by JIRA. - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (ISPN-647) Remote InboundInvocationHandler should differentiate between various cache inavailabilities

by Manik Surtani (JIRA)

Remote InboundInvocationHandler should differentiate between various cache inavailabilities ------------------------------------------------------------------------------------------- Key: ISPN-647 URL: https://jira.jboss.org/browse/ISPN-647 Project: Infinispan Issue Type: Feature Request Components: RPC Affects Versions: 4.2.0.ALPHA1, 4.1.0.Final Reporter: Manik Surtani Assignee: Manik Surtani Fix For: 4.2.0.BETA1, 4.2.0.CR1 Currently a RequestIgnoredResponse is returned to any caller if either of these happen: * The cache is not yet started, is in the process of starting, and times out. * The cache doesn't exist. * The cache has been stopped. The latter two should use a different response type - CacheUnavailableResponse ? - that would not trigger a retry or any abort of transactions. -- 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-317) when unsafeReturnValues is false, combine put, remove, replace, putIfAbsent, to pull back responses in 1 command

by Mircea Markus (JIRA)

when unsafeReturnValues is false, combine put, remove, replace, putIfAbsent, to pull back responses in 1 command ---------------------------------------------------------------------------------------------------------------- Key: ISPN-317 URL: https://jira.jboss.org/jira/browse/ISPN-317 Project: Infinispan Issue Type: Feature Request Reporter: Mircea Markus Assignee: Manik Surtani Fix For: 4.1.0.CR1 at the moment this is split in two operations: a remote get followed by an put. Optimize this to only reside in one operation. -- 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-1345) Dirty reads may occurs on mutable objects

by Christophe Labouisse (JIRA)

Dirty reads may occurs on mutable objects ----------------------------------------- Key: ISPN-1345 URL: https://issues.jboss.org/browse/ISPN-1345 Project: Infinispan Issue Type: Bug Components: Transactions Affects Versions: 5.0.0.FINAL Environment: Windows Java 1.6.0_26 Reporter: Christophe Labouisse Assignee: Manik Surtani In local mode, I create a cache like this: {code} cacheManager = new DefaultCacheManager(); cacheManager.getDefaultConfiguration().fluent().storeAsBinary().transaction().cacheStopTimeout(5000); final Configuration config = new Configuration().fluent().transactionManagerLookup(this.tmLookup).locking() .isolationLevel(IsolationLevel.READ_COMMITED).build(); this.cacheManager.defineConfiguration("Gruik", config); this.cache = this.cacheManager.getCache("Gruik"); {code} When retrieving data using {{cache.get(_key_)}} I find out that Infinispan returns the object instance actually stored in the cache datastore. This is OK when the inserted objects are immutable but fails to achieve isolation when using mutable objects. For instance on a simple Pojo with a {{get/setValue}}. ||Step||Reader||Writer|| |1|Starts transaction| | |2|{{value = cache.get(KEY);}}| | |3|{{System.out.println(value.getValue());}} Prints 42| | |4| |Starts transaction| |5| |{{value = cache.get(KEY);}} Same instance than step 2| |6| |{{value.setValue(666); // Prepare update}}| |7|{{System.out.println(value.getValue());}} Prints 666 !| | |8|{{value = cache.get(KEY);}} Same instance than step 2| | |9| |{{cache.put(KEY,value);}}| |10| |Commits transaction| |11|{{value = cache.get(KEY);}} Same instance than step 2| | |12|{{System.out.println(value.getValue());}} Prints 666| | |13|Commits transaction| | According to the READ_COMMITTED specification, the value returned printed on step 7 should be 42, as the setting to 666 is not committed yes. -- This message is automatically generated by JIRA.

[JBoss JIRA] Created: (ISPN-1272) Move away from javadoc's aggregate goal

by Galder Zamarreño (JIRA)

Move away from javadoc's aggregate goal --------------------------------------- Key: ISPN-1272 URL: https://issues.jboss.org/browse/ISPN-1272 Project: Infinispan Issue Type: Enhancement Components: Build process Reporter: Galder Zamarreño Assignee: Manik Surtani Priority: Minor Fix For: 5.2.0.FINAL We should move away from maven javadoc's aggregate goal because it creates a lot of pains. For starters, it often spawns a separate process, -- This message is automatically generated by JIRA. For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (ISPN-1213) TreeCache expires parents that have children

by Todd Ciezadlo (JIRA)

TreeCache expires parents that have children -------------------------------------------- Key: ISPN-1213 URL: https://issues.jboss.org/browse/ISPN-1213 Project: Infinispan Issue Type: Bug Components: Eviction Affects Versions: 4.2.1.FINAL Reporter: Todd Ciezadlo Assignee: Manik Surtani TreeCache parents expire according to the max-idle value even if they contain children. This puts the tree cache in an inconsistent state since the "dangling" children can be retrieved through TreeCache.get(FQN, String) calls, but cannot be traversed to through TreeCache.getRoot() and Node.getChildren() calls. Copied a unit test to Steps to Reproduce. -- This message is automatically generated by JIRA. For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (ISPN-761) Cache.keySet(), entrySet(), values(), size() ignore contents of cache loader

by Paul Ferraro (JIRA)

Cache.keySet(),entrySet(),values(),size() ignore contents of cache loader ------------------------------------------------------------------------- Key: ISPN-761 URL: https://jira.jboss.org/browse/ISPN-761 Project: Infinispan Issue Type: Bug Components: Loaders and Stores Affects Versions: 4.2.0.BETA1 Reporter: Paul Ferraro Assignee: Manik Surtani Passivated cache entries are not represented in values returned by the keySet(), entrySet(), values(), and size() Cache methods. This results in inconsistent behavior, since it is possible that a given cache key may not be contained in keySet() even though Cache.get(...) would return a non-null value if the entry was previously passivated. I think CacheLoaderInterceptor needs to implement the following methods: Object visitSizeCommand(InvocationContext ctx, SizeCommand command) throws Throwable Object visitValuesCommand(InvocationContext ctx, ValuesCommand command) throws Throwable Object visitEntrySetCommand(InvocationContext ctx, EntrySetCommand command) throws Throwable Object visitKeySetCommand(InvocationContext ctx, KeySetCommand command) throws Throwable -- 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-791) On node startup, ensure all peers have compatible configurations

by Manik Surtani (JIRA)

On node startup, ensure all peers have compatible configurations ---------------------------------------------------------------- Key: ISPN-791 URL: https://jira.jboss.org/browse/ISPN-791 Project: Infinispan Issue Type: Feature Request Components: Configuration Affects Versions: 4.1.0.Final Reporter: Manik Surtani Assignee: Manik Surtani Fix For: 5.0.0.BETA1, 5.0.0.Final This is to prevent caches that are supposed to be symmetric/identical from being misconfigured. Some elements are allowed to be unique, of course, such as bind addresses in JGroups as well as node names, server hints, certain props passed to cache stores, etc. A simple test could be a hash (MD5 or SHA1?) of the config XML (or a serial form of the generated Configuration bean) which is exchanged as a part of the join method. On failure of the hash check, the entire object could be checked, and if that fails as well, an appropriate ConfigurationException could be thrown. -- This message is automatically generated by JIRA. - For more information on JIRA, see: http://www.atlassian.com/software/jira
