* NO-JIRA: Fix for potential Timer deadlock issue:Andrew Stitcher2012-07-051-9/+46
| | | | | | | | | | | | | | | | | - Previously we used a mutex to prevent cancelling a TimerTask whilst it was still executing from within its callback in another thread. This violates the principle that you shouldn't hold locks when calling the arbitrary code in a callback, and so is subject to potential deadlock problems. - This fix only works if no timer callback calls TimerTask::cancel(); this is true with the current code. And there is no good reason to call cancel() from within a callback, as cancel is the default behviour in any case - you have to specifically reschedule a recurring timer. git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk/qpid@1357827 13f79535-47bb-0310-9956-ffa450edef68
* QPID-3280: Performance problem with TTL messages.Alan Conway2011-06-151-0/+6
| | | | | | | | | | | | When sending a large number of messages with nonzero TTLs to a cluster, overall message throughput drops by around 20-30% compared to messages with TTL 0. The previous approach to TTL in the cluster is replaced with a simpler "cluster clock". Also QueueCleaner is executed in the cluster timer, and modified to be deterministic in a cluster. git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk/qpid@1136170 13f79535-47bb-0310-9956-ffa450edef68

* NO-JIRA: Fix qpidd late/overran warnings.Alan Conway2011-03-181-4/+6
| | | | | | | Warnings for late-and-overrun tasks were not being correctly reported. Lateness for overrun tasks below the late threshold were not being reported. git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk/qpid@1082954 13f79535-47bb-0310-9956-ffa450edef68
* Aggregate Timer warnings.Alan Conway2010-11-171-18/+11
| | | | | | | | | | | | The Timer code logs a warning if a timer callback is started late or overruns the start time for the next callback. In cases where there are a lot of these warnings, the time taken to do the logging itself severly worsens the situation. This commit aggregates timer warnings and give a statistical report every 5 seconds at most. git-svn-id: https://svn.apache.org/repos/asf/qpid/trunk/qpid@1036169 13f79535-47bb-0310-9956-ffa450edef68
