message expiration and 5.0.0 snap shot version
Hello Active MQ users/developers ,
Our application is currently using Actiive MQ
4.1.1 version. We have an embedded broker in Tomcat 5.5 , without
persistence , durable subscribers and Topic publishers , with a time to
live of 5 minutes for the messages. I have observed that messages when
not consumed remain even after 5 minutes. This is know bug AMQ-1112. In
the JIRA bug tracking tool it is specified that this bug is fixed in
5.0.0 snap shot. If I upgrade to 5.0.0 snap shot , will I get the
needed functionality without any major issues in the usage of (durable
susbcribers , topic publishers , no persistence, embedded broker ).
Please let me know. Our application will go into production in
beginning of next month.
Also what is the difference between a release version and a snap shot
version ?? is release version more stable ?
When is the 5.0.0 release version scheduled ?
thank you,
Suchitha

You can find the new features in 5.0 here :
http://activemq.apache.org/new-features-in-50.html.
I would suggest to checkout the latest source from trunk if you want to
dive into the code details :
http://activemq.apache.org/source.html
there are a lot of unit test cases that provides a lot of example there
:-)
As for the message cursors you can start at the
org.apache.activemq.broker.region.cursors and
org.apache.activemq.broker.region.policy package.
Regards,
Jonas

Thank you so much Jonas; The internal implementation details of
active mq's 5.0 snapshot which you have mentioned "message cursors for
persistent messages" can it be found online on active web site ? How do
we get to know,the code details , data structures used etc ?

Unless you're tied up to jdk 1.4, I don't think there's going to be any
major issues here with regards to the features you mentioned. FWIW, some
of the major improvements in 5.0 includes use of Java 5, message cursors
for persistent messages , different store format for some store
implementations and a bunch of bug fixes.

I would not necessarily consider a release version as more stable than a
snapshot. A snapshot version includes a list of improvements/fixes
that's committed after a release was made.

I would not necessarily consider a release version as more stable than a
snapshot. A snapshot version includes a list of improvements/fixes
that's committed after a release was made.
