Javier Pedemonte commented on SHINDIG-1330:
-------------------------------------------
STATUS OF LATEST PATCH (SET #4)
* Adds new pubsub-2 feature.
* Adds the following new APIs:
- gadgets.byId()
- gadgets.rpc.config()
- For setting config parameters on rpc connection. Right now only
takes a security callback.
- gadgets.rpc.removeReceiver()
- gadgets.rpc.getReceiverOrigin()
* Updated NIX transport to support parent verification, given a valid relay
file.
* Updated WPM transport to check origin on message reception. Also added checks
for non-async WPM and Opera 9.x's use of "event.domain" instead of
"event.origin".
* Hook for possible frame phishing in rpc.js, given a valid relay file.
QUESTIONS/REMAINING ISSUES
* Not sure of the best place to put gadgets.byId(). For now, I've put it in
core.util/util.js, but that needs to be fixed.
* In shindig-container.js, since OpenAjax Hub creates the iframe, needed to
split code up into two cases: the case where gadget requires the 'pubsub-2'
feature and therefore uses OAA Hub to create and manage the iframe; and the
existing case where the iframe is created in shindig-container.js. This code
isn't pretty, since I need to do a metadata request for the gadget. Ideally, I
should be using the new container code (the 'shindig.container-1.0' feature),
since it fetches and caches the gadget metadata on the container side. Will
this new container code be the default container for Shindig 2.0?
* Not sure about gadgets.rpc.config(). Need a way to set the security callback
function. In a previous discussion, we decided to go with config() rather than
a function specifically for the callback (see
http://wiki.opensocial.org/index.php?title=PubSub.next_Proposals#Secure_rpc),
since we could expand it in the future for other uses.

> http://wiki.opensocial.org/index.php?title=Incorporate_Open_Ajax_Hub_as_Pub-Sub_Mechanism_for_OpenSocial_1.next
> While there are still more work, the patch provides a new pubsub feature
> which uses OAHub as the underlying eventing model.
> The /content/container/sample-pubsub-2.html demonstrates a simple pubsub
> example using the feature.
