svn commit: r1176126 - in /tomcat/tc6.0.x/trunk: ./ STATUS.txt
java/org/apache/tomcat/util/net/NioEndpoint.java webapps/docs/changelog.xml
Author: kkolinko
Date: Mon Sep 26 23:12:02 2011
New Revision: 1176126
URL: http://svn.apache.org/viewvc?rev=1176126&view=rev
Log:
Simplify code in NioEndpoint$Poller.
The events.size() call is costly, because it is a loop that counts entries in a linked queue.
Actually it is not needed here at all, because we iterate the queue by ourselves.
Removed commented-out code (no need for explicit sync when it is ConcurrentLinkedQueue)
and one unused import.
It is backport of r1173614 of trunk, r1173619 of TC7.

- getStuckThreadIds() returns a list of ids. It might be useful to
have a similar method that returns Thread.getName() names.
-* Replace unneeded call that iterated events queue in NioEndpoint.Poller.
- There is no need to call size() on a liked list to check whether it is empty,
- especially if it is followed by us iterating the list by ourselves.
