[JBoss JIRA] (ISPN-3194) Create diagnostics dumping tool
by Manik Surtani (JIRA)

Manik Surtani commented on ISPN-3194:
-------------------------------------
[~NadirX] - there is a bit here ( https://access.redhat.com/site/solutions/221103 ) about JDR but it doesn't really tell you what is being captured from the runtime. It seems to be more of a tool to zip up configs and logs. Do you have any more info on JDR?

> A simple script that an end-user can run on an existing cluster, that will:
> 1. Connect to a given node via JMX
> 2. Get a list of all caches on all nodes
> 3. Run JMX calls on each cache on each node to capture diagnostic data
> 4. Serialise this data (maybe JSON?), zip it up.
> This will allow end-users to share such stats for debugging and perf tuning.
> Diagnostic data to be captured would include all JMX info on hit/miss ratio, RPC performance, transaction commit/rollback rates, config details, time budgeting info, etc.
> This tool would require that JMX statistics are enabled and running for a while before the snapshot is captured.

[JBoss JIRA] (ISPN-3452) Hot Rod client socket leak
by Michal Linhard (JIRA)
[ https://issues.jboss.org/browse/ISPN-3452?page=com.atlassian.jira.plugin.... ]
Michal Linhard commented on ISPN-3452:
--------------------------------------
BTW this is a hotrod client problem, but ISPN JIRA project still hasn't Client component defined so I've put it under "Remote protocols"
This is not a very well formed test but it reproduces the situation I'm talking about:
https://github.com/mlinhard/infinispan/commit/839022bad269565282bfc3b4df3...
I'm creating a server that just simply closes all the connections it accepts and an idle RemoteCacheManager that just sits there and it's evictor thread creates a new TcpTransport object every 500ms, pings the server and gets TransportException("End of stream reached!") which is swallowed.
sample output here (TRACE on org.infinispan.client.hotrod)

Normally we should also see "Successfully closed socket" message after TcpTransport is destroyed. but that doesn't happen.
good tool to see that Sockets are still open is http://file-leak-detector.kohsuke.org/ (pointed out by Mitchell on the forum)

[JBoss JIRA] (ISPN-3451) Read-after-write semantics in transactional mode
by Pedro Ruivo (JIRA)
[ https://issues.jboss.org/browse/ISPN-3451?page=com.atlassian.jira.plugin.... ]
Pedro Ruivo commented on ISPN-3451:
-----------------------------------
True, GMU achieves (Extended-) Updated Serializability. So, if you have a read operation, you will see both A and B equals to 1 or A and B equals to 2 depending if your tx starts after or before the commit of the write transaction.
Of course we have the cost of keeping multiple versions for a key in the data container and more restrict validation phase. Also, read-only transactions can read a old snapshot (i.e. it's not the most recent). but that snapshot is always consistent!

[JBoss JIRA] (ISPN-3451) Read-after-write semantics in transactional mode
by Mircea Markus (JIRA)
[ https://issues.jboss.org/browse/ISPN-3451?page=com.atlassian.jira.plugin.... ]
Mircea Markus commented on ISPN-3451:
-------------------------------------
Even if the entries would be committed in a defined order in which they hace been written, the problem still exists due to Infinispan's distributed nature.
For simplicity let's consider that both A and B are owned by N1 and N2.
There is a moment in which the TX is committed on N2 but not yes committed on N1.
All the tx that would read the data from N2 would see the new value, the others seeing the old one.
If the users really require this semantic, they should use Flag.FORCE_WRITE_LOCK on read operations as well.
Possible that [~pruivo]'s GMU to handle this scenario implicitly, Pedro care to comment?
