==================================
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.
Bug reporting
-------------
Please report bugs related to multiprocessing at the `Python bug
tracker <http://bugs.python.org/>`_. Issues related to the packaging of
multiprocessing should be reported at `<http://code.google.com/p/python-multiprocessing/>`_.

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.
2.6.1.1 -- 2009-02-07
---------------------
* Fixed an issue with `make doc`
* mp docs - fix issues 4012,3518,4193 (Python svn: r67419)
* 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`_.
* issue 4301: patch logging to add processName, remove the old
_check_logger_class code (Python svn: r68737)
* Resolve issue 3321: (segfault) _multiprocessing.Connection()
doesn't check handle (Python svn: r68768)
* Documentation update
2.6.0.2 -- 2008-11-27
---------------------
The release is based on 2.6.0+ and contains additional fixes
from Python svn.
* Issue #5: Added monkey patch to make the threading module forward
compatible with Python 2.6 and 3.0.
* Python Issue #4204: Fixed a compilation issue on FreeBSD 4.
* Removed ``install`` target from Makefile.
* Updated comments of Modules/mmapmodules.c. The modifications
and origin are clearly marked now.
* Added sphinx builder for docs and new make target ``docs``.
* Changed version schema to Python.version.number.internal_revision
* Pulled doc fixes from Python svn: r67189, r67330, r67332
2.6.0-0.1 -- 2008-10-27
-----------------------
The release is based on Python 2.6.0.
* Initial release
