[jboss-jira] [JBoss JIRA] Commented: (JGRP-499) JChannel.startFlush does not pass down timeout

Vladimir Blagojevic commented on JGRP-499:
------------------------------------------

Note that this timeout is not the timeout parameter configured at FLUSH protocol level. There are two timeouts in FLUSH:

timeout configured at protocol level that represent the maximum time channel will be blocking down messages irregardless of flush success. so even if something goes terribly wrong with FLUSH channel will unblock channel.down() after timeout expires.

internal timeout that you are referring to is maximum timeout allowed for first FLUSH phase to finish. First flush phase involves START_FLUSH, FLUSH_OK, FLUSH_COMPLETED messages until the cluster becomes quiet. If FLUSH does not reach end of first flush phase (due to flush collisions) then flush is repeated with simple back off algorithm.

> JChannel.startFlush() does not pass down the timeout in the Suspend event.
> This causes a fixed timeout of 4000 to be used on flushes:
> Flush.java:
> case Event.SUSPEND:
>   return startFlush(evt, 4000, 5, false);
> The SUSPEND event may or may not take a View as the arg, so, something will have to be done to pass the timeout down. Perhaps a Map as the event arg with "timeout" and "view" as possible keys?
