Subject [jira] [Closed] (AMQ-4468) TimeStampPlugin doesn't work with Stomp
Date Tue, 28 May 2013 17:18:20 GMT


Timothy Bish closed AMQ-4468.

    Resolution: Not A Problem

Test added to activemq-stomp StompTimeStampingBrokerPluginTest which does what was described
in this issue, two messages sent with timestamp set for previous day, and a set expiration.
 One message received, then wait for the set expiration time and observe that the second message
is no longer on the Queue.

>    Affects Versions: 5.8.0
>         Environment: Ubuntu 12.04.1 LTS Precise, OpenJDK Runtime Environment (IcedTea7

>         Attachments:
> Stomp producers cannot set the JMSTimestamp or timestamp header. Activemq always adds
a timestamp header and overrides a set value. Therefore, the expires header cannot be recalculated
according to Activemq time according to the description for TimeStampPlugin. TimeStampPlugin
works for JMS producers because the JMSExpiration UTC can be adjusted up/down according to
the difference between JMSTimestamp and Activemq UTC.
> Example:
> ActiveMQ time is 2pm UTC
> Stomp producer time is 1:03pm UTC.
> Stomp expires time is 1:03pm + 15 minutes: 1:18pm UTC.
> ActiveMQ will throw this message away with TimeStampPlugin enabled.
> ActiveMQ will deliver this message for a JMSProducer.
> Recommendation:
> 1)
> ActiveMQ should allow Stomp producers to set a timestamp or JMSTimestamp header.
> if( Stomp Message Timestamp Header ) {
> use header
> }
> else {
> add timestamp header
> }
> 2)
> Add the disableTimeStampsByDefault=true feature to the stomp protocol URI.
