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.

fbdf2bed49 Add out_sync filter category. 
Added option to XMLStream.send() to skip applying filters.

Filters in the out_sync group are synced with placing stanza content
either on the wire directly or into the send queue. Because of this,
out_sync filters should not block.

2923f56561 Pre-parse StanzaPath paths to speed up matching. 
The parsing and namespace cleaning isn't terribly expensive, but it does
add up. It was adding an extra 5sec when processing 100,000 basic
message stanzas.

4274f49ada Remove stream feature handlers on session_start. 
Based on profiling, using around 35 stream handlers quarters the number
of basic message stanzas that can be processed in a second, in
comparison to only using the bare minimum of four handlers.

To help, we can drop handlers for stream features once the session
has started. So that we can re-enable these handlers when a stream
must restart, the 'stream_start' event has been added which fires
whenever a stream header is received.

The 'stream_start' event is a more generic replacement for the
existing start_stream_handler() method.

f6e30edbc4 Log received data AFTER filtering. 
This allows applications to filter out sensitive information, such
as passwords, so that it won't appear in the logs.

It does mean that the debug logs will not show the actual received
data, and there will be no indication of tampering, unless the
filter author explicitly logs and notes that a change was made.

eff3330e75 Add support for incoming/outgoing filters. 
A filter accepts and returns a stanza, but potentially modified.

To prevent sending/receiving a stanza, a filter may return None.

Incoming:
    self.add_filter('in', in_filter)

Outgoing:
    self.add_filter('out', out_filter)

Filters are applied in the order thay are added. However, you may
add an order parameter, which is the place in the list to insert the
filter:

    self.add_filter('in', in_filter, order=0)

efe1b9f5a9 Allow sending stanzas on session_end. 
May set self.disconnect_wait=True so that all disconnect
calls wait for the send queue to empty, unless explicitly
overridden with wait=False.

The session_end now fires before closing the socket so
that final stanzas may be sent, such as unavailable presences
for components.

862a2a1440 Ensure that reconnection happens properly after connection loss. 
Calling reconnect() simultaneously from multiple threads (like when

deb52ad350 This change stops sleekxmpp from spending huge amounts of time unnecessarily computing logging data that may never be used. This is a HUGE performance improvement; in some of my test runs, unnecessary string creation was accounting for > 60% of all CPU time. 
Note that using % in a string will _always_ perform the sting substitutions, because the strings are constructed before the function is called. So log.debug('%s' % expensiveoperation()) will take about the same CPU time whether or not the logging level is DEBUG or INFO. if you use , no substitutions are performed unless the string is actually logged
