Hi all,
we think there were really great discussions on what features a new
AJAX layer of qooxdoo should have. I have now started to create a new
one, which is based on many ideas of Chris Ricks. Thank you again Chris.
You're all welcome - it was fun. :-)
We have some other ideas added. We want a special request (QxRequest)
and response (QxResponse) object to handle the data between the
different communication layers in qooxdoo. Also we think to have a
queue is great. But we think it is better placed outside the xmlhttp
related stuff. We have done this in our new class QxRequestQueue. This
class create instances of the class QxTransport which handles the
wrapping to the different transport implementations. For example this
could be the classical xmlhttp (QxXmlHttpTransport) or iframes
(QxIframeTransport).
This concept allows us to add new transport implementations easily if
they appear on the horizon.
There are some possibilities of Chris Ricks work missing. Like
timeouts for example. This is something I think should be placed in
QxRequestQueue, too. QxRequestQueue is somewhat basic currently and
does no real queuing.
At present, The QxHttpTransportQueue class will queue requests when
given the right parameters (setting the active limit and queue limit
appropriately).
Additionally, QxHttpTransport does do timeouts - see the addTimeout
method and _pumpTimeouts method.
As I have no more time to work on these classes before the final
release of the next version of qooxdoo, this will be also the versions
of the release. Afterwards we will continue the work. You are all
invited to help. Chris, sorry, I hope I have not dis encouraged you
with our plans and decisions. I would really like it, if you could
help us, to extend and modify the newly existing stuff to your needs.
No problem. :-)
For any further work, please keep the new code more prototype style
and try to omit to send complete full-working classes. We should
really discuss the additions and changes in detail before coding them.
Thanks.
I'll follow the discussion - with any luck the stuff that I've written
should still prove useful.
Best regards,
Chris
