Re: Transaction issues with openjpa.streaming=false

Sun, 29 Apr 2012 22:38:04 -0700 

Hi Adam,
The first to do is to open a JIRA and use it to track things down. If you think the issue is in the mailbox code, use https://issues.apache.org/jira/browse/MAILBOX, otherwise use https://issues.apache.org/jira/browse/IMAP. 


Then, all the trick resides in replicating the exception with a coded 
test (not with a real client). Once the test is there and clearly 
reproduce the issue, the solution should be easy to find.



I go from the idea that the issue is a concurrency issue. Should this 
not be the case, the information here after is still applicable.


There are 3 places where you could implement the test:


1. In the JPA unit tests. For example, we a now a stresstest that 
launches multiple append operations (see 
https://svn.apache.org/repos/asf/james/mailbox/trunk/jpa/src/test/java/org/apache/james/mailbox/jpa/JPAStressTest). 
Easy localized code but only applicable to JPA (although you can 
replicate to other mailbox impl extending an Abstract test), but does 
not simulate an IMAP client.



2. In the mailbox integration tests. At the moment, tests are run 
sequentially and there is nothing done to run in parrallel.  You should 
look then how to enhance the test framework to deal with this.

https://svn.apache.org/repos/asf/james/mailbox-integration-tester/trunk/


3. The postage project 
(https://svn.apache.org/repos/asf/james/postage/trunk/). This one need 
is still for james 2.3 and would need a large upgrade. It could simulate 
traffic load, but with less control on the executed scenarii.



Feel free to choose one of these (I would personally go for 1 to begin, 
and maybe 2 after).


Thx,

Eric

I wouldn't be against getting my hands dirty. Would you mind pointing me in
the right direction to where I maybe able to help?

Thx for the precision Adam.

I am using maildir and would take some time in the coming days to setup
something on openjpa with various clients.

As a side note, our integration tests are mono-thread, we need to migrate
to something more multi-threaded.

For example, I have identified deadlocks on maildir impl, but it's hard to
reproduce and fix without those multi-threaded tests.

Thx,

Eric

Eric,

Sorry I wasn't clear. I meant that when I go to access a mailbox, I would
wait a minute and then try again. Each time I would let it time out and
try
again to see if it was just a temporary condition, but this is consistent
every time I attempt to access a mailbox. I attempted to access different
folders with the same client.

Thanks,
Adam

  Eric,

This happens when I'm loading a folder via IMAP.  Below is from the logs
where I attempted to access a folder twice.



Adam, You mean you access the same mailbox twice?
Do you perform this with the same client? What is the delay between the 2
access requests?

Thx,
Eric



  Thanks,

Adam

  Hi Adam,



There has been some changes between M2 and M4 regarding the way uid is
generated and how the lock is managed for it.

Does this arise further to a particular operation (I suppose it is
further
a smtp in)? (look at the log lines before the stacktrace).

Thx,
Eric
