* Updated prompt request code to support the new silent execution mechanism. * Improved frontend tracking of request ids. This should ensure that it is safe to use the frontend's kernel manager without confusing it.

""" Greedy completer extension for IPython
Normal tab completer refuses to evaluate nonsafe stuff. This will evaluate
everything, so you need to consider the consequences of pressing tab
yourself!
Note that this extension simplifies readline interaction by setting
only whitespace as completer delimiter. If this works well, we will
do the same in default completer.

MONKEYPATCHED VERSION (ipy_greedycompleter.py)
Assuming the text is of the form NAME.NAME....[NAME], and is
evaluatable in self.namespace or self.global_namespace, it will be
evaluated and its attributes (as revealed by dir()) are used as
possible completions. (For class instances, class members are are
also considered.)
WARNING: this can still invoke arbitrary C code, if an object
with a __getattr__ hook is evaluated.
