Map/Reduce test failures in master
by Manik Surtani
Guys (probably Vladimir)
Does anyone know what's up here? I see these fail sporadically:
Failed tests: testinvokeMapReduceOnAllKeys(org.infinispan.distexec.mapreduce.DistributedTwoNodesMapReduceTest): Error removing cache
testCombinerDoesNotChangeResult(org.infinispan.distexec.mapreduce.DistributedFourNodesMapReduceTest): Error removing cache
testinvokeMapReduceOnAllKeysWithCollator(org.infinispan.distexec.mapreduce.DistributedFourNodesMapReduceTest): Error removing cache
testinvokeMapReduceOnAllKeysWithCollatorAsync(org.infinispan.distexec.mapreduce.DistributedFourNodesMapReduceTest): org.infinispan.CacheException: Error removing cache
I presume I am not alone here?
Cheers
Manik

Release 5.2.CR1
by Mircea Markus
Hi,
Even though there has been a sustained push and many of the NBST issues raised are now either in master or with pending pull requests, the general feeling is that the 5.2 master is not yet CR ready.
In order to allow time to finish some pending JIRAs and to integrate what we already have in the queue, next Infinispan release(Beta3 or CR1) is postponed to 25 Oct.
Cheers,

Including CENTRAL_LOCK in our stacks, COUNTER
by Sanne Grinovero
Hi all,
I'm still in a prototyping phase, but for the next big feature of
Hibernate Search & Infinispan Query it looks like the LockService from
JGroups would be exactly what I need.
My only concern about using it is that people will have to reconfigure
JGroups from Infinispan, or even worse to reconfigure the stack in
AS7.
Would it be possible to include this in our default stacks? Including
the one provided by AS7 ?
I have a very similar requirement for Hibernate OGM to rely on COUNTER
for the CounterService... same question, different use case.
Regards,
Sanne

All the better if I'm wrong, as we will solve both problems with one
fix. :)
I don't see it yet though. I attached new logs to ISPN-2330 with a
little more information (clearer indication of when the problem is
caused in jbossas-clustering-SYNC-tcp-0/standalone/log/server.log).
Both the ContextClassResolver and the ExtendedRiverMarshaller are
created well after the last JBossMarshalling.stop() occurred. Also, if
we are creating a new ExtendedRiverMarshaller and using that when this
failure occurs, that should have nothing to do with any JBossMarshaller
instances.
Also note that the jbossmarshaller.stop() is only logged at the
beginning of the testsuite run and near the end (in
jbossas-clustering-SYNC-tcp-0/standalone/log/server.log).

admin operations for xsite replication
by Mircea Markus
Hi,
Re: https://issues.jboss.org/browse/ISPN-2320
Here is a list of admin operations I'd like to implement for ISPN-2320:
- status: shows a map with all defined sites and their status: available xor offline
- takeOffline: takes a site offline, i.e. backup to that site is ignored
- takeOnline: the reverse to takeOffline
- amendTakeOffline (int:afterFailures, long:minTimeToWait): changes the takeOffline functionality[1]
- statistics: numberOfBackupCalls, successfullBackupCalls, failedBackupCalls
Each of the operations that modify configs would be available on a per node or on a per cluster basis (a flag to the operation would differentiated between the two).
How does that sound? Any other operations you might think of?

Infinispan 5.1.x Object marshalling with and without a class table in use and unmarshalling smacking its head against the wall...
by Scott Marlow
ReplicableCommandExternalizer.writeCommandParameters() can marshall an
instance of class org.infinispan.util.ImmutableListCopy (as a
ID_EXTERNALIZABLE_CLASS) fine. If the classtable doesn't know about the
org.infinispan.util.ImmutableListCopy class, we also marshall the AS7
module name (org.infinispan) and module slot name (main). The
marshalled byte output looks something like the following (this is the
successful case). I apologize for the crappy hex/character dump :).
Each hex value is preceded by '0x' and followed by an extra space separator.
*class table does not have ImmutableListCopy class case*

P0xCB 0x8E 20x9E 0xD0
Notice that the "org.infinispan.util.ImmutableListCopy" (on middle of
fourth line) is followed by about 10 separator bytes (of some importance
I'm sure :). After the 10 separator bytes, is the module name
(org.infinispan) and that is followed by more separator bytes and then
the module slot name (main). Again, this is the *working case*.
If the classtable does have an entry for the
org.infinispan.util.ImmutableListCopy class,
ReplicableCommandExternalizer.writeCommandParameters() appears to
instead write out some binary values that unmarshalling won't know how
to deal with later. The hexdump for the *failing case* looks like:
*class table does have ImmutableListCopy class case*

In the above, the "org.infinispan.util.ImmutableListCopy" field is
followed by various bytes but no module name.
Later during when unmarshalling this payload, we reach code that doesn't
understand how to unmarshall. http://pastie.org/5043963 shows the
failing callstack (partially below for your convenience). It seems to
me, that somewhere in unmarshalling (Object) code, we need to check if a
class table was used and use the marshalled form instead.

This is recreating on the AS 7.1 branch, with jboss-marshalling 1.3.17.x
and Infinispan 5.1.x.
I'll get closer to understanding the problem, but I need to hear from
the Infinispan champion of marshalling and class table handling. So, I
can coordinate effort with him/her. I also wanted to share what we are
seeing as well with the team. :)

State transfer performance
by Mircea Markus
Hi ,
One of the targets of NBST is to minimise the downturn in throughput during topology changes. And now that NBST is getting there, I think that a test to measure how long does it take to a node to join, under different levels of cluster load, is very desirable in order to see where we are and also to help us profile and improve the state transfer performance.
Martin, are we doing this kind of performance testing? It would be nice to have it integrated in Radargun or something similar in order to be able to quickly run it.
Cheers,

eviction + listeners in a local cache with unbounded container
by Adrian Nistor
Hi,
I've encountered a strange situation where eviction listeners are not
invoked although eviction otherwise works perfectly.
I use a local cache with no eviction policy. Looking at the code in
DataContainerFactory I can see this leads to an unbounded data container
which does not broadcast eviction notifications.
Now the problem is when I use a put and specify a lifespan (ie. V
BasicCache.put(K key, V value, long lifespan, TimeUnit lifespanUnit,
long maxIdleTime, TimeUnit maxIdleTimeUnit)) it behaves a bit strange -
the entry is evicted when lifetime expires but no listeners are notified
of the eviction. Is this behaviour intended or is it a bug? I think it
would make more sense to invoke those listeners. Now it seems to behave
as if eviction notification mechanism is disabled just because there is
no default life time set at cache level.
Cheers,
Adrian

RAC: Reliable Asynchronous Clustering
by Bela Ban
Hi all,
I've come up with an alternative to sync TX updates across sites. It's
based on the requirement that we need high reliability between sites,
but yet it isn't feasible to run 2PCs across sites. RAC [1] is supposed
to be almost as fast as async replication and close to the reliability
sync replication provides.
I've published the design at [1], and we'll present it in more detail at
our clustering meeting in Palma early November.
Comments and feedback are welcome !
