Subject [jira] Updated: (POOL-93) Reduce contention by making borrow & return more independent from each other
Date Fri, 24 Nov 2006 15:26:03 GMT
     [ http://issues.apache.org/jira/browse/POOL-93?page=all ]

Holger Hoffstätte updated POOL-93:
----------------------------------

    Attachment: GKOP-relaxedSyncOnReturn.patch

Patch for making returnObject & invalidateObject less synchronized. All unit tests still
pass, even with massive slashdotting (100+ threads).

> Currently borrow & return are completely blocked from each other, while at least
the factory-based validation & destruction can be handled independently. A few simple
changes narrow the synchronization blocks yet retain overall correctness.
