[richfaces-issues] [JBoss JIRA] (RF-12219) Push: Test that messages do not become stale in a queue

[ https://issues.jboss.org/browse/RF-12219?page=com.atlassian.jira.plugin.s... ] Lukáš Fryč edited comment on RF-12219 at 7/27/12 5:15 AM: ---------------------------------------------------------- Hi Milo, looked once again to your fix, it seems okay in case of single window per single client. However each client and each browser window needs to establish own connection to the server. Why? Each client (browser tab/window) is subscribed to particular set of topics, and each PushSession own queue of messages to be delivered to those topics. If you would connect more requests to the same session, then you are getting Message Queueing concept instead of Topic Subscription. Basically first client comes, first serves. ---- In detail, each client request which [finds out there are messages in Session's queue|https://github.com/richfaces/core/blob/4cef088fcee550d2d7f0fd4a1b71...], it initiates broadcasting and once broadcasting ends, it [clears sent messages|https://github.com/richfaces/core/blob/4cef088fcee550d2d7f0fd4a1...], making them unavailable to further requests. Additionally there can be only [one request per session|https://github.com/richfaces/core/blob/4cef088fcee550d2d7f0fd4a1b...]. ---- You should be able to simulate this problem by opening two tabs in one browser - messages will be delivered just to one of them. was (Author: lfryc): Hi Milo, looked once again to your fix, it seems okay in case of single window per single client.
