Hi guys,
due to some critical race in my application using the UpdateLock
method I converted my application
to use the Wt::WServer::post.
Basicaly what I'm doing is now:
Wt::WServer::instance()->post(theSessionId,
boost::bind(&WtTerminal::swapModel,
this,
myDataModelBuffer));
Due the fact the calls are now asynchronus I have to make the object
instances (this) passed to the
post to survive the Session, otherwise some posts are called on dead objects.
So in WtTerminal DTOR I have to wait that all queued posts where
called or discarded (due
the session id not found) or that the sessionId is not valid.
Looking at the API it doesn't seems this is possible. Is there a way I
didn't see?
I have tried this:
Wt::WServer::instance()->post(boost::bind(&WtTerminal::postsDone,
const_cast<WtTerminal*>(this)));
(supposing all the posts are threated in a FIFO policy) and then
waiting that the method has been
called, but the Wt::WServer::post(const boost::function<void()>&) is private.
It doesn't seem that a Wt::WApplication instance can emit a signal
when is destroyed ( I can inherit from
it and specialize the WApplication::finalize() in order to emit a message).
It would be usefull if the Wt::WServer::instance()->post(const
std::string& sessionID, ....) could take two
function. The first is called if the sessionId exists, the second if
the sessionId doesn't exist ( I can provide
a patch for this in case).
Regards
Gaetano Mendola
