Merge: make the coordinator remain the same if possible after a merge
---------------------------------------------------------------------
Key: JGRP-1002
URL: https://jira.jboss.org/jira/browse/JGRP-1002
Project: JGroups
Issue Type: Feature Request
Reporter: Bela Ban
Assignee: Bela Ban
Fix For: 3.0
When we have {C, A, B} and split into {C,A} and {B}, then a merge will produce {A,B,C}. Therefore the coord is moved from C to A. For certain apps, e.g. JBoss singletons, this is not good, as we're moving the singleton services from a perfectly healthy node to a different node.
GOAL: come up with a deterministic policy of picking a coord such that we minimize coord switching if the existing coord is still member of the cluster.
This depends on or is related to the flexible coord pick policy JIRA issue

TCLFilter doesn't work in jboss 5 with war's in any documented way
------------------------------------------------------------------
Key: JBAS-6532
URL: https://jira.jboss.org/jira/browse/JBAS-6532
Project: JBoss Application Server
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: Logging
Affects Versions: JBossAS-5.0.0.GA
Environment: jdk 6, linux
Reporter: robert lazarski

Reading this doc:
http://www.jboss.org/community/docs/DOC-12203
Indicates a *-exp.war syntax is needed for TCLFilter war use, but there are no files of that type on my system running jboss 5. I've tried all the possible combinations I can think of, posted the problem to the forum, and the result is always that the file sizes and contents of the log files generated are exactly the same for the different war's, ie, no separated content. Here's my current config:
<appender name="penguinLog" class="org.apache.log4j.FileAppender">
<errorHandler class="org.jboss.logging.util.OnlyOnceErrorHandler"></errorHandler>
<param name="Append" value="false"/>
<param name="File" value="${jboss.server.home.dir}/log/penguinLog.log"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d %-5p %c{1} %m%n"/>
</layout>
<filter class="org.jboss.logging.filter.TCLFilter">
<param name="AcceptOnMatch" value="true"/>
<param name="DeployURL" value="penguin"/>
</filter>
</appender>
<appender name="wtfLog" class="org.apache.log4j.FileAppender">
<errorHandler class="org.jboss.logging.util.OnlyOnceErrorHandler"></errorHandler>

[JBoss JIRA] Created: (JBREM-552) cannot init cause of ClassCastException
by John Mazzitelli (JIRA)
cannot init cause of ClassCastException
---------------------------------------
Key: JBREM-552
URL: http://jira.jboss.com/jira/browse/JBREM-552
Project: JBoss Remoting
Issue Type: Bug
Security Level: Public (Everyone can see)
Affects Versions: 2.0.0.Beta2 (Boon)
Reporter: John Mazzitelli
Assigned To: Tom Elrod
Priority: Minor
Fix For: 2.0.0.CR1 (Boon)
I'm in a catch clause within InvokerRegistry and I'm getting a weird exception thrown:
java.lang.IllegalStateException: Can't overwrite cause
at java.lang.Throwable.initCause(Throwable.java:320)
at org.jboss.remoting.InvokerRegistry.loadClientInvoker(InvokerRegistry.java:447)
at org.jboss.remoting.InvokerRegistry.createClientInvoker(InvokerRegistry.java:324)
at org.jboss.remoting.Client.connect(Client.java:385)
at org.jboss.on.communications.command.client.JBossRemotingRemoteCommunicator.getRemotingClient(JBossRemotingRemoteCommunicator.java:470)
at org.jboss.on.communications.command.client.JBossRemotingRemoteCommunicator.send(JBossRemotingRemoteCommunicator.java:430)
at org.jboss.on.communications.command.client.AbstractCommandClient.invoke(AbstractCommandClient.java:167)
at org.jboss.on.communications.command.client.ClientCommandSender.send(ClientCommandSender.java:820)
at org.jboss.on.communications.command.client.ServerPollingThread.run(ServerPollingThread.java:102)
Look at line 447 and you'll see it is trying to init the cause of a ClassNotFoundException. Running in a debugger, the newly constructed exception created on 446 has a null cause. Looking then at Throwable.initCause and you'll see a null cause causes this IllegalStateException to be thrown. The cause needs to be "this", not null (I don't know why, seems like it should also look for null, but whatever - that's the way the JDK is written).
The fix is simple - use the constructor that takes a throwable as its second parameter. Not sure why initCause it being used, as opposed to this constructor.
e.g.:
new ClassNotFoundException("Can not invoke loadClientInvokerClass method on " + transportFactoryClass, e);
(notice the ", e" parameter).
There are three other instances where initCause is called on ClassNotFoundException that also need to be fixed. See the other catch clauses in here.

[JBoss JIRA] Created: (JGRP-809) Copyless stack
by Bela Ban (JIRA)
Copyless stack
--------------
Key: JGRP-809
URL: https://jira.jboss.org/jira/browse/JGRP-809
Project: JGroups
Issue Type: Feature Request
Reporter: Bela Ban
Assignee: Bela Ban
Fix For: 2.8
Currently (as of 2.7), the transport reads the contents of a received packet into a buffer, then passes a *copy* of the buffer to a thread from the OOB or incoming thread pools. To prevent this copy, we can
- have the receiver read only the version and OOB flag (to see which thread pool to dispatch the packet to)
- pass a ref to the socket to a thread from the incoming of OOB pool, have that thread read the packet and return
- each thread in the pool has its own buffer into which the buffer is read from the socket
Possibly use NIO: we can install a selector and get woken up whenever data to be read is present. At that point, we can pass the ref to the socket to the handler thread and return immediately. NIO with channels for multicast sockets is available only in JDK 7 (or 8?), so this is a bit off... However, we can already implement this with reading the version and flags bytes and then passing the socket to the handler
