A bug in FF3's sync XHRs ?

[Jorge]

Either a synchronous call isn't what I believe it to be, or there's a
bug in FF3 :

IOW : Why does the onclick handler of the button "SYNC" return (in
FF3) before the XHR has completed ?

Click it several times in a row, and it will post several concurrent
XHRs ...

Because of luck of debugging info in sync request (in your link) I can
not say for sure what is happening, but by the look of it, the sync
request is being submitted in async mode and processing continues...
Somebody mentioned a bug in FF (3?) with sync mode AJAX requests in
your previous thread... Maybe this is it...

Yes, that's what is happening.

Here's the code of the SYNC button :

sync.onclick= function () {
var a, xhr= new XMLHttpRequest();
xhr.open("GET", "xhrData.txt?"+Math.random(), ** false ** );
xhr.send(null);
//dummy do-something-else-just-in-case before returning
//See cljs thread 2
a= 1;
};

If you can monitor the network traffic you'll see that pressing it
once produces a traffic of x (KB/s), pressing it twice yields 2x, etc.
IOW: the synchronous XHRs are being posted asynchronous and
concurrently.
