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

IqError and IqTimeout now extend XMPPError, so if you don't care
about the difference, you can use:
try:
self.do_something_with_iqs()
except XMPPError:
# Error? Timeout? I don't care!
pass
If you do need to distinguish between timeouts and error replies,
you can still continue to use:
try:
self.do_somethin_with_iqs()
except IqError as err:
pass
except IqTimeout:
pass
If you don't catch any Iq errors and you're processing a stanza
then an error response will be sent, just like normal if you raise
XMPPError or any other exception, except that the error messages
will be generic to prevent leaking too much information.

The error bubbles through the event processing loop, breaking it and
hanging the application.
Instead, there is now a .exception(e) method on XMLStream which may
be overridden or reassigned that will receive all unhandled exceptions
(read: not XMPPError) from event and stream handlers.
|
|
This allows exceptions to include the original
content of a stanza in the error response by including
the parameter clear=False when raising the exception.
|
|
May now use sys.excepthook to catch exceptions
from threaded handlers.
|
|
We now raise the unexpected exceptions instead of sending
them on the network.
- avoids flood (sending a traceback on a MUC, for example…) and
maybe some security issues.
- lets you handle the traceback (catch it to handle
it properly, or with except_hook, etc)
- an exception cannot be raised without you knowing
|
|
Each module should now log into its own logger.
|
|
Stanza objects now accept the use of underscored names.
The CamelCase versions are still available for backwards compatibility,
but are discouraged.
The property stanza.values now maps to the old getStanzaValues and
setStanzaValues, in addition to _set_stanza_values and
_get_stanza_values.
