The :mod:`io` module provides the Python interfaces to stream handling. The
builtin :func:`open` function is defined in this module.
messages at different log levels. This allows you to instrument your code with
debug messages, for example, but turning the log level down so that those debug
messages are not written for your production system. The default levels are
-``CRITICAL``, ``ERROR``, ``WARNING``, ``INFO``, ``DEBUG`` and ``UNSET``.

The logger, handler, and log message call each specify a level. The log message
is only emitted if the handler and logger are configured to emit messages of

noncoders to easily modify the logging properties.

--------------

will need to override this :meth:`emit`.
+Useful Handlers
+---------------
+
In addition to the base :class:`Handler` class, many useful subclasses are
provided:
#. :class:`FileHandler` instances send error messages to disk files.
-#. :class:`BaseRotatingHandler` is the base class for handlers that rotate log
- files at a certain point. It is not meant to be instantiated directly. Instead,
- use :class:`RotatingFileHandler` or :class:`TimedRotatingFileHandler`.

+
+#. :class:`TimedRotatingFileHandler` instances send error messages to
+ disk files, rotating the log file at certain timed intervals.
+
+#. :class:`SocketHandler` instances send error messages to TCP/IP
+ sockets.
-#. :class:`RotatingFileHandler` instances send error messages to disk files,

-#. :class:`SocketHandler` instances send error messages to TCP/IP sockets.
+#. :class:`SysLogHandler` instances send error messages to a Unix
+ syslog daemon, possibly on a remote machine.
-#. :class:`DatagramHandler` instances send error messages to UDP sockets.
+#. :class:`NTEventLogHandler` instances send error messages to a
+ Windows NT/2000/XP event log.
-#. :class:`SMTPHandler` instances send error messages to a designated email

+#. :class:`MemoryHandler` instances send error messages to a buffer
+ in memory, which is flushed whenever specific criteria are met.
-#. :class:`SysLogHandler` instances send error messages to a Unix syslog daemon,
- possibly on a remote machine.
+#. :class:`HTTPHandler` instances send error messages to an HTTP
+ server using either ``GET`` or ``POST`` semantics.
+
+#. :class:`WatchedFileHandler` instances watch the file they are
+ logging to. If the file changes, it is closed and reopened using the file
+ name. This handler is only useful on Unix-like systems; Windows does not
+ support the underlying mechanism used.
+
+.. currentmodule:: logging
-#. :class:`NTEventLogHandler` instances send error messages to a Windows
- NT/2000/XP event log.
+#. :class:`NullHandler` instances do nothing with error messages. They are used
+ by library developers who want to use logging, but want to avoid the "No
+ handlers could be found for logger XXX" message which can be displayed if
+ the library user has not configured logging. See :ref:`library-config` for
+ more information.
-#. :class:`MemoryHandler` instances send error messages to a buffer in memory,
- which is flushed whenever specific criteria are met.
+.. versionadded:: 3.1
-#. :class:`HTTPHandler` instances send error messages to an HTTP server using
- either ``GET`` or ``POST`` semantics.
+The :class:`NullHandler` class was not present in previous versions.
-The :class:`StreamHandler` and :class:`FileHandler` classes are defined in the
-core logging package. The other handlers are defined in a sub- module,
-:mod:`logging.handlers`. (There is also another sub-module,
-:mod:`logging.config`, for configuration functionality.)
+The :class:`NullHandler`, :class:`StreamHandler` and :class:`FileHandler`
+classes are defined in the core logging package. The other handlers are
+defined in a sub- module, :mod:`logging.handlers`. (There is also another
+sub-module, :mod:`logging.config`, for configuration functionality.)
Logged messages are formatted for presentation through instances of the
:class:`Formatter` class. They are initialized with a format string suitable for
name. If this feature is used, messages sent to the named logger and its
children are allowed through the filter, and all others dropped.
+Module-Level Functions
+----------------------
+
In addition to the classes described above, there are a number of module- level
functions.
StreamHandler
^^^^^^^^^^^^^
-.. module:: logging.handlers
-
The :class:`StreamHandler` class, located in the core :mod:`logging` package,
sends logging output to streams such as *sys.stdout*, *sys.stderr* or any
file-like object (or, more precisely, any object which supports :meth:`write`
Outputs the record to the file.
+NullHandler
+^^^^^^^^^^^
+
+.. versionadded:: 3.1
+
+The :class:`NullHandler` class, located in the core :mod:`logging` package,
+does not do any formatting or output. It is essentially a "no-op" handler
+for use by library developers.
+
+.. class:: NullHandler()
+
+ Returns a new instance of the :class:`NullHandler` class.
+
+
+ .. method:: emit(record)
+
+ This method does nothing.
+
+See :ref:`library-config` for more information on how to use
+:class:`NullHandler`.
WatchedFileHandler
^^^^^^^^^^^^^^^^^^
+.. currentmodule:: logging.handlers
+
The :class:`WatchedFileHandler` class, located in the :mod:`logging.handlers`
module, is a :class:`FileHandler` which watches the file it is logging to. If
the file changes, it is closed and reopened using the file name.
A program is free to modify this list for its own purposes.

+ Module :mod:`site` This describes how to use .pth files to extend
+ :data:`sys.path`.
