Jigsaw News

Devel News

The following lines are just describing some bug fixes and enhancements that happened recently, it is edited by hand and is far from being complete (We forgot to update it quite often). We plan to have an automatically updated version based on cvs commit. Also we don't put resolution time, which may be useful to understand that doing XML based serialization of resources takes more than one day ;)

The current work on Jigsaw is focused on stability and HTTP/1.1 comformance, thanks to the great work done on CoAdvisor by The Measurement Factory.

(20050527) Fixed client connection deletion in connection reuse, it was leading to a leak in the client hashtable (and to lots of connections in CLOSE_WAIT).
(20050516) Fixed bug in DateParser (wrong timezone offset) thanks to Menno Jonkers
