[JBoss JIRA] (ISPN-3389) Forwarded transactions can remain stale after state transfer
by Erik Salter (JIRA)

---------------------------------
Summary: Forwarded transactions can remain stale after state transfer
Key: ISPN-3389
URL: https://issues.jboss.org/browse/ISPN-3389
Project: Infinispan
Issue Type: Bug
Components: State transfer
Affects Versions: 5.2.7.Final
Reporter: Erik Salter
Assignee: Mircea Markus
There is a scenario where a tx started on one node, moved during state transfer, and committed on the originating node won't be removed from the new owner's tx table.
The chain of events is as follows:
1. New topology comes in as part of a view change.
2. Local transaction started with the new topology ID. This transaction was started due to a LockControlCommand and has no modifications. Also important, it only has local locks.
3. Tx forwarded to new owner.
4. Since the tx has only local locks and no modifications, it is only removed locally. No TxCompletion or Rollback are broadcast to the new owners.
This key becomes unusable not due to stale locks, but because the waitForTransaction() code will see that the old tx can "potentially" lock the key.

[JBoss JIRA] (ISPN-3387) AsyncStore preload is slow, when given database datastore

Summary: AsyncStore preload is slow, when given database datastore
Key: ISPN-3387
URL: https://issues.jboss.org/browse/ISPN-3387
Project: Infinispan
Issue Type: Task
Components: Loaders and Stores
Affects Versions: 5.3.0.Final
Environment: database datastore, with AsyncStore
Reporter: Laszlo Hadadi
Assignee: Mircea Markus
Priority: Minor
Currently AsyncStore.loadAll() method strategy is suboptimal.
actually loadAll do this:
getAll keys from cache
itarate on keys and load each value from store.
This is can be really costly when we have db persistance behind async store.
cost:
1 query for keys + number of keys query.

Radoslav Husar <rhusar(a)redhat.com> made a comment on [bug 900549|https://bugzilla.redhat.com/show_bug.cgi?id=900549]
@Aleks, the fix have made it to 6.1.1.ER4, not earlier.
> Manual eviction should not delete entry from cache store

> Key: ISPN-2903
> URL: https://issues.jboss.org/browse/ISPN-2903
> Project: Infinispan
> Issue Type: Bug
> Components: Eviction
> Affects Versions: 5.2.3.Final
> Reporter: Paul Ferraro
> Assignee: Galder Zamarreño
> Priority: Critical
> Labels: 5.2.x, jdg6
> Fix For: 5.2.5.Final, 5.3.0.Alpha1, 5.3.0.Final

> Attachments: AtomicMapServlet.java, AtomicMapTestCase.java, server.log, server.log

> Here's the scenario:
> Given 2 nodes with REPL_SYNC cache with passivating cache store (e.g. default web cache in AS7).
> 1. Create cache entry containing atomic map with 2 map entries on node1.
> 2. Passivate that cache entry on node2 via manual evict.
> 3. Modify 1 of the atomic map entries within the cache entry on node1.
> 4. Lookup atomic map on node2. It only contains 1 map entry - the map entry modified in step 3. The other map entry is lost.
> It's a side effect of ISPN-2384, where some changes were made to tighten the passivation/activation scenarios, but it did not cover manual eviction calls.

[JBoss JIRA] (ISPN-3366) Data loss when entry forwarding to primary owner and primary owner shutdown

Dan Berindei commented on ISPN-3366:
------------------------------------
Right, {{strictPeerToPeer}} is only available in the standalone Infinispan configuration, and not in the Infinispan Server configuration.

Looks like we don't have strictPeerToPeer configuration in Infinispan Server 5.2.x.
