Howard M. Lewis Ship updated TAP5-2134:
---------------------------------------
Assignee: Howard M. Lewis Ship
Labels: thread-safety (was: )
Priority: Major (was: Blocker)
Description: Tapestry 5.4 introduced session locking, whereby access to the
HttpSession is serialized when multiple threads are active for the same session
(this can occur in some Ajax scenarios). This has been highly controversial,
and (at the very least), it should be optional, controlled by a configuration
symbol. (was: Version: 5.4-alpha-9
For example:
In an event handler there are statements as following, the int1 is persisted,
try {
int1 ++;
Thread.sleep(10000);
} catch (InterruptedException e) {
e.printStackTrace();
}
All the methods with same HTTP session will get blocked until that thread is
awaken.
This issue is not existing in 5.3.6.
I'll attach a test page to show it.
Thanks.
)
Summary: Session locking (introduced in 5.4) should be optional (was:
A blocked method would like to block other methods too, when there is write
access to a persisted field.)
