About
-----

`multiprocessing` is a back port of the Python 2.6/3.0 `multiprocessing <http://docs.python.org/library/multiprocessing.html>`_
package. The multiprocessing package itself is a renamed and updated version of 
R Oudkerk's `pyprocessing <http://pypi.python.org/pypi/processing/>`_ package.
This standalone variant is intended to be compatible with Python 2.4 and 2.5, 
and will draw it's fixes/improvements from python-trunk.

This package would not be possible if not for the contributions of not only
the current maintainers but all of the contributors to the original pyprocessing
package listed `here <http://pyprocessing.berlios.de/doc/THANKS.html>`_

The multiprocessing package monkey patches several aspects of the `threading`
module to make it forward compatible with Python 2.6. The patches are 
non-intrusive and don't change existing functions. See `multiprocessing.patch`
for detailed informations.

Please refer to `<http://www.python.org/doc/2.6/library/multiprocessing.html>`_
for more information about the `multiprocessing` package.

===========
Changes
===========

2.6.2.1 -- 2009-07-30
---------------------

 * Issues #5155, 5313, 5331: multiprocessing.Process._bootstrap was
   unconditionally calling "os.close(sys.stdin.fileno())" resulting in file
   descriptor errors

 * Issue #5400: Added patch for multiprocessing on netbsd compilation/support

 * Fix and properly document the multiprocessing module's logging
   support, expose the internal levels and provide proper usage
   examples.

 * Issue #5261: Patch multiprocessing's semaphore.c to support context
   manager use: "with multiprocessing.Lock()" works now.

 * Issue #3321: _multiprocessing.Connection() doesn't check handle; added checks
   for *nix machines for negative handles and large int handles. Without this
   check it is possible to segfault the interpreter.

 * Issue #4301: Patch the logging module to add processName support, remove
   _check_logger_class from multiprocessing.

 * issue4238: bsd support for cpu_count (Python svn: r67423)

 * Move definition int sval into branch of ifdef where it is used.
   Otherwise, you get a warning about an undefined variable.
   (Python svn: r67440)

 * Fixed a segfault in connection_recvbytes_into() which occured
   with Python debug builds on 64bit Linux.

 * Added reference to `Issue 1683 http://bugs.python.org/issue1683`_.
