4190027a78 Prevent xmlns="" in stream output. 
This was causing problems for HTML-IM because the HTML is parsed
without a namespaced context.

While xmlns="" technically can be valid, it's usually wrong, so this will work
for now until the HTML-IM parsing is fixed.

f6e1fecdf8 Add Collector stanza handler class. 
This style of handler is necessary for capturing result sets from
queries that use multiple messages to send the results instead of
in a single result stanza. Notably, XEP-0313 (MAM).

e510875f64 Fix certificate expiration scheduler 
timedelta.seconds does not store the total seconds of a time span.
Internally, seconds is the next smaller unit to days, hence
timedelta.seconds will never exceed (or reach) the number of seconds
in a day (60*60*24=86400)

e3fab66dfb Allow tasks to remove themselves during execution 
The scheduler class is now capable with dealing with tasks which remove
themselves from the scheduler during execution.

Additionally, some optimizations were applied by use of iterators and
some functions better suited for the purpose.

Please peer-review, all tests pass.

strings so they don't need to be parsed multiple times.

e918a86028 Make the error message better regarding hanged threads. 
All event handlers which call disconnect() MUST be registered using
`add_event_handler(..., threaded=True)` in order to prevent temporarily
deadlocking until a timeout occurs.

This is required because disconnect() waits for the main threads to
exit before returning, including the event processing thread. Since
handlers registered without `threaded=True` run in the event processing
thread, the disconnect() call will deadlock.

bf8a9dc20d Add logging note about potential cause of disconnect() deadlock. 2012-04-29 14:48:14 -07:00
Lance Stout
08716c35fd Set a timeout when waiting for threads. 
If calling disconnect() from a non-threaded event handler, deadlock can
happen as disconnect() is waiting for threads to close, but the event
runner is blocked by a handler waiting for disconnect() to return.

It is best to specify threaded=True for event handlers which may call
disconnect().

a1ddd88208 Add support for a new type of stanza interface: bool 
The set of bool_interfaces provides default behaviour for
checking/setting the presence of empty subelements.

The prime example of this would be:

    bool_interfaces = set(['required'])

This would mean that ``stanza['required']`` would return ``True`` for:

    <stanza>
       <required />
    </stanza>

and ``False`` for:

    <stanza />

Likewise, assigning ``stanza['required'] = True`` would add an empty
``<required />`` element, and setting it to ``False`` would remove
such an element if it exists.
