Infinispan inside OSGI
----------------------
Key: ISPN-800
URL: https://jira.jboss.org/browse/ISPN-800
Project: Infinispan
Issue Type: Feature Request
Components: Core API
Affects Versions: 4.2.0.CR1
Reporter: luca stancapiano
Assignee: Manik Surtani
We need to import infinispan inside a OSGI repository. Tests are made with Felix.
I added the configuration to use infinispan inside a osgi repository. We need to ignore all listed dependencies. With this configuration we can install infinispan-core.jar inside OSGI. Its achievement will be as a base installation here: https://github.com/flashboss/infinispan
I added the Import-Package because you are forced to put manually in Felix all dependencies as jgroups, jboss marshalling, jcip, all apache commons. I've seen infinispan core working by default without all those libraries, so I think the same achievement should be replicated in OSGI.
Inside the Import-Package tag I excluded those libraries so Infinispan core can be started in default mode without errors. If we want use the replication in OSGI, it is enough add manually the other packages (jgroups.jar etc etc)
Actually the core bundle can be installed. But to be used it needs theese projects be installed as osgi bundles:
jboss transaction api 1.0.1.GA
(It is not yet a OSGI bundle. Waiting for a response to: https://jira.jboss.org/browse/JBEE-67)
jgroups 2.10.1.GA
(fixed in jgroups 1.12)
river 1.2.3.GA
marshalling-api 1.2.3.GA
jboss common core 2.2.14.GA
jboss logging spi 2.0.5.GA
rhq plugin annotations 1.4.0.B01
i18nlog 1.0.9
log4j 1.2.16
We should make sure proper 'Import-Package' property is specified in the MANIFEST.MF so that:
1- it fails to load obviously when there's any missing bundles that are essential in using the very core functionality of Infinispan.
2 - it does not fail due to the dependency that is not really essential.

[JBoss JIRA] Created: (ISPN-1195) Rehashing and state transfer to use digesting
by Manik Surtani (JIRA)
Rehashing and state transfer to use digesting
---------------------------------------------
Key: ISPN-1195
URL: https://issues.jboss.org/browse/ISPN-1195
Project: Infinispan
Issue Type: Feature Request
Components: Distributed Cache, State transfer
Affects Versions: 5.0.0.FINAL
Reporter: Manik Surtani
Assignee: Dan Berindei
Priority: Critical
Fix For: 5.1.0.BETA1, 5.1.0.Final
Rather than pushing entire state to new joiners, a mechanism of digests should be used to minimise network transfers. For example, Merkle trees can be used to determine which entries are out of date and need pushing, in the case of nodes that persist to a local cache store, and is restarted but still has access to some state on disk.
This would require versioned entries though.

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

Enable Hot Rod clients to start transactions
--------------------------------------------
Key: ISPN-375
URL: https://jira.jboss.org/jira/browse/ISPN-375
Project: Infinispan
Issue Type: Feature Request
Components: Cache Server
Reporter: Galder Zamarreno
Assignee: Galder Zamarreno
Fix For: 5.1.0.BETA1, 5.1.0.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.
