If you create a WebCore timer with an timeout of 0 that should allow
you to perform a reasonably low latency action on the main thread.

WebKit is not thread-safe. If you want to perform external
processing on a secondary thread, that's OK, but any calls into the
DOM will have to happen on the main thread.

Hi all,
I am trying to make a wrapper in C++ for the Ivy protocol for OWB
(I think it could work on Webkit even though I have not tested)
that could world entirely in javascript. Ivy is a light-weigh
publish/subscribe protocol. It is based on callback functions that
you call when a regExp is seen on the bus.
My main problem is that the thread that calls back functions is
the thread that handles incoming transmissions, that is not one of
Webkit threads.
As my problem seems close to what is done in XMLHttpRequest, I
have tried mecanisms used by that class and particularly reusing
the code from JSAbstractEventListener::handleEvent to call my
object. The callback seems to work but developing a javascript
application on top of that lead me to discover that some part of
javascript are not working : for example, accessing some (not all)
element with document.getElementById("...") does return "null" in
the callback (but works in the Webkit threads) even though I could
access it directly in C++ through Document::getElementById.
I do not know much about what I have done wrong but I am eager to
do the necessary debugging and testing.
Maybe also my method is not the best so if someone has a better
idea, he is more than welcome.
Thanks,
Julien
