From: Xuefer@21cn.com Operating system: Window2000 PHP version: 4.0.4pl1 PHP Bug Type: *Session related Bug description: session blocking, version: all including 4.0.4pl1 session blocking? ----------------- when session start started in the multi-framed webpage if one frame did not finished running(keeping-alive and conneting), the other frame(using the same session id) will blocked until that frame finished ----------------- often, an web-irc would like to keep one frame alive until user quit, when running it does soemthings, but other frames not work this time!!! this problem not only bad for that keeping-alive php program to sessoin, but also bad for normal multi-frame's run speed, becos only one php running for 1 user, if no blocking, 2 or more running the same time. if i use session_set_save_handle to use my own save handle, the problem went! is that the problem which internal session save handle used the file lock? locking sessoin file until php program exited and session saved? so how the other frame used by the same user works well? ----------------- pls, fix it, find a way but if fixed, another problem still covered perhaps both frame1.php and frame2.php running if frame1.php changed the session, will it effect in frame2 immediately? ----------------- example is in: http://www.phpwizard.net/phpChat it use http://www.phpwizard.net/phpIRC it works ok it php3, becos phpChat have its own session support, and was turned off in php4 so session blocking in php4 -- Edit Bug report at: http://bugs.php.net/?id=9442&edit=1
