Using arbitrary objects as messages
-----------------------------------
In the preceding sections and examples, it has been assumed that the message
passed when logging the event is a string. However, this is not the only
possibility. You can pass an arbitrary object as a message, and its
:meth:`__str__` method will be called when the logging system needs to convert
it to a string representation. In fact, if you want to, you can avoid
computing a string representation altogether - for example, the
:class:`SocketHandler` emits an event by pickling it and sending it over the
wire.
Optimization
------------
Formatting of message arguments is deferred until it cannot be avoided.
However, computing the arguments passed to the logging method can also be
expensive, and you may want to avoid doing it if the logger will just throw
away your event. To decide what to do, you can call the :meth:`isEnabledFor`
method which takes a level argument and returns true if the event would be
created by the Logger for that level of call. You can write code like this::
if logger.isEnabledFor(logging.DEBUG):
logger.debug("Message with %s, %s", expensive_func1(),
expensive_func2())
so that if the logger's threshold is set above ``DEBUG``, the calls to
:func:`expensive_func1` and :func:`expensive_func2` are never made.
There are other optimizations which can be made for specific applications which
need more precise control over what logging information is collected. Here's a
list of things you can do to avoid processing during logging which you don't
need:
+-----------------------------------------------+----------------------------------------+
| What you don't want to collect | How to avoid collecting it |
+===============================================+========================================+
| Information about where calls were made from. | Set ``logging._srcfile`` to ``None``. |
+-----------------------------------------------+----------------------------------------+
| Threading information. | Set ``logging.logThreads`` to ``0``. |
+-----------------------------------------------+----------------------------------------+
| Process information. | Set ``logging.logProcesses`` to ``0``. |

you don't import :mod:`logging.handlers` and :mod:`logging.config`, they won't
take up any memory.

Because of Python semantics, a shelf cannot know when a mutable

Now what happens when the user writes ``from sound.effects import *``? Ideally,
one would hope that this somehow goes out to the filesystem, finds which

this operation does not work very well on Windows platforms, where the
