Comparison between arbitrary python objects can get crazy, whereas we really
only care about if the JSON state we are syncing is different. So with this change,
we store and check against the JSON state.
javascript doesn't guarantee the order of AJAX requests,
so we give `Session.delete` and `Kernel.kill` a callback signature.
Changing the kernel type calls `Notebook.start_kernel`,
which terminates the previous session, if defined,
before starting the new one.
A flag is stored, to prevent multiple simultaneous attempts to start sessions, raising a SessionAlreadyStarting Error,
preventing the spec_changed event from firing.
can happen if a message is waiting in a pipe and the web socket is closed before the message is handled.
And give ZMQChannels a nice repr with their kernel ID
Sometimes for consistency or efficiency purposes, it makes sense to update
a group of properties all at once. This context manager makes this possible.
We also fix a bug where send_state was not passing the key on to get_state.
Instead of automagically instantiating a comm when it is accessed, require a call to open(). This makes the comm attribute much less magical, and hopefully more understandable.
This will immediately create a model on the javascript side when a widget is created. This means that, for example, a widget that only interacts with its model can work without "displaying" it.
You get a cryptic error message from iptest if mistune is not installed.
