[JBoss JIRA] (ISPN-6504) Try to use the index even if the query matches all entries

by Adrian Nistor (JIRA)

[JBoss JIRA] (ISPN-2575) KeyTransformer registration is required on all nodes of the cluster, in case of custom keys

by Mircea Markus (JIRA)

[ https://issues.jboss.org/browse/ISPN-2575?page=com.atlassian.jira.plugin.... ] Mircea Markus updated ISPN-2575: -------------------------------- Assignee: Adrian Nistor (was: Sanne Grinovero) > KeyTransformer registration is required on all nodes of the cluster, in case of custom keys > ------------------------------------------------------------------------------------------- > > Key: ISPN-2575 > URL: https://issues.jboss.org/browse/ISPN-2575 > Project: Infinispan > Issue Type: Enhancement > Components: Querying > Affects Versions: 5.2.0.Beta5 > Reporter: Anna Manukyan > Assignee: Adrian Nistor > Attachments: ClusteredCacheTest.java > > > The case is the following: > I have a clustered cache on which I want to perform a search. I'm doing the following: > I'm initializing SearchManager on node1, I'm registering a custom key transformer for my key using the created searchmanager, but then when I'm trying to put data into the cache on node1 (which is in REPL_SYNC mode with cache on node2), I'm getting the exception: > java.lang.IllegalArgumentException: Indexing only works with entries keyed on Strings, primitives and classes that have the @Transformable annotation - you passed in a class org.infinispan.query.test.CustomKey3. Alternatively, see org.infinispan.query.SearchManager#registerKeyTransformer > When I'm initializing the SearchManager using node2 cache and register the keyTransformer on it as well, then everything works perfectly, even though I am not using the second created SearchManager. > The test which reproduces the issue is attached to the jira.

[JBoss JIRA] (ISPN-3906) Do not place ProtobufValueWrapper instances in the cache

[JBoss JIRA] (ISPN-3835) Index Update command is processed before the registry listener is triggered

[JBoss JIRA] (ISPN-375) Enable Hot Rod clients to start transactions

by Tristan Tarrant (JIRA)

[ https://issues.jboss.org/browse/ISPN-375?page=com.atlassian.jira.plugin.s... ] Tristan Tarrant updated ISPN-375: --------------------------------- Fix Version/s: 9.3.0.Final (was: 9.2.0.Final) > Enable Hot Rod clients to start transactions > -------------------------------------------- > > Key: ISPN-375 > URL: https://issues.jboss.org/browse/ISPN-375 > Project: Infinispan > Issue Type: Feature Request > Components: Remote Protocols > Reporter: Galder Zamarreño > Assignee: Pedro Ruivo > Priority: Blocker > Fix For: 9.3.0.Final > > > It might be useful to allow Hot Rod clients to start transactions within Hot Rod servers. The possibility of clients participating in the actual transaction, i.e. being an XAResource, should not be imposed since this might be less than trivial to achieve in non-Java environments. The alternative would be to allow clients to start Hot Rod server local transactions only. > This would require enhancing Hot Rod spec to have some begin/commit/rollback commands that return a tx id, and for clients to be able to send this id as part of each command that should participate in the transaction. > Pitfalls to avoid include avoiding a transaction to be propagated over several Hot Rod servers. IOW, to simplify things, if a tx is started in server A, all ops within that tx should be directed to tx. Load balancing could still happen but would need to be tx sticky. -- This message was sent by Atlassian JIRA (v7.5.0#75005)

[JBoss JIRA] (ISPN-4286) Two concurrent putIfAbsent operations can both return null during rebalance

[JBoss JIRA] (ISPN-4159) DefaultTwoWayKey2StringMapper encodes objects to strings in a manner that is incompatible with string handling of some databases

by Tristan Tarrant (JIRA)

Strings are kept unmodified. > 2. it uses a special prefix (unicode char 0xfeff) to mark which strings were encoded and which are plain. > Unfortunately some databases, notably MySql, interpret the endianness mark (0xfeff, 0xfffe), convert to native byte order and then drop it. > This leaves us with no clue the string is not an actual String but an encoded representation of another type. This misinterpretation leads later to ClassCastExceptions in various places in core and user code. > Proposed fix: get rid of #1 and #2 optimisations. Encode all objects, including Strings and always use the ?n prefix (where n stands for the original type). Drop the 0xFEFF marker prefix. -- This message was sent by Atlassian JIRA (v7.5.0#75005)

[JBoss JIRA] (ISPN-3918) Inconsistent view of the cache with putIfAbsent in a non-tx cache during state transfer
