http://issues.apache.org/bugzilla/show_bug.cgi?id=35746 ------- Additional Comments From [EMAIL PROTECTED] 2006-10-01 13:44 ------- Just to clarify, I proposed 2 ways of avoiding unexpected session expiration. a) on the looping/sleeping thread, detect time shifts and pass it along the stackframes to whichever class wants to know. This is when the looping code know to few about the task to perform, for example if the looping thread doesn't know the job is to assert/expire sessions, but it can pass its knowledge of time and time shifts. That's the piece of code. b) the looping/sleeping thread knows it has to age sessions. Valves or filters (whatever on service()) simply resets the age to 0. Note that if the duration of a sleep/wait could be affected by a system time change, rolling back time 1 hour could lock up a thread for 1 more hour. The old way of expiring session would be just as affected because which ever thread checks for session expiration, it also calls wait/sleep. There is no other jvm primitive to perform such pause. Therefore, the implementation would be just as flawed in the worst case, and fairly expiring session in the best case. - - - As for wait()/sleep() JLS specs (JVM spec doesn't mention it): http://java.sun.com/docs/books/jls/third_edition/html/memory.html#17.8.1 "If this is a timed wait, an internal action removing t from m's wait set that occurs after at least millisecs milliseconds plus nanosecs nanoseconds elapse since the beginning of this wait action." http://java.sun.com/docs/books/jls/third_edition/html/memory.html#17.9 "Thread.sleep causes the currently executing thread to sleep (temporarily cease execution) for the specified duration, subject to the precision and accuracy of system timers and schedulers." -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
