* Sun Dec 01 2013 email@example.com
- Update to version 126.96.36.199:
+ Now also sets ``multiprocessing.current_process`` for compatibility
with loggings ``processName`` field
* Wed Nov 13 2013 firstname.lastname@example.org
- Update to version 188.8.131.52
+ Now works without C extension again.
+ New ``_billiard.read(fd, buffer, [len, ])` function
implements os.read with buffer support (new buffer API)
+ New pure-python implementation of ``Connection.send_offset``.
- Changes from 184.108.40.206
+ All platforms except for Windows/PyPy/Jython now requires the C extension.
- Changes from 220.127.116.11
+ Fixed problem with Python3 and setblocking.
- Changes from 18.104.22.168
+ Now works on Windows again.
- Changes from 22.214.171.124
+ ApplyResult.terminate() may be set to signify that the job
must not be executed. It can be used in combination with
+ Pipe/_SimpleQueue: Now supports rnonblock/wnonblock arguments
to set the read or write end of the pipe to be nonblocking.
+ Pool: Log message included exception info but exception happened
in another process so the resulting traceback was wrong.
+ Pool: Worker process can now prepare results before they are sent
back to the main process (using ``Worker.prepare_result``).
- Changes from 126.96.36.199
+ Pool: New ``correlation_id`` argument to ``apply_async`` can be
used to set a related id for the ``ApplyResult`` object returned:
>>> r = pool.apply_async(target, args, kwargs, correlation_id='foo')
+ Pool: New callback `on_process_exit` is called when a pool
process exits, with signature ``(pid, exitcode)``.
+ Pool: Improved the too many restarts detection.
- Changes from 188.8.131.52
+ Dual code base now runs on Python 2.6+ and Python 3.
+ No longer compatible with Python 2.5
+ Includes many changes from multiprocessing in 3.4.
+ Now uses ``time.monotonic`` when available, also including
fallback implementations for Linux and OS X.
+ No longer cleans up after receiving SIGILL, SIGSEGV or SIGFPE
+ ``Finalize`` and ``register_after_fork`` is now aliases to multiprocessing.
It's better to import these from multiprocessing directly now
so that there aren't multiple registries.
+ New `billiard.queues._SimpleQueue` that does not use semaphores.
+ Pool: Can now be extended to support using multiple IPC queues.
+ Pool: Can now use async I/O to write to pool IPC queues.
+ Pool: New ``Worker.on_loop_stop`` handler can be used to add actions
at pool worker process shutdown.
Note that, like all finalization handlers, there is no guarantee that
this will be executed.

- Update to 188.8.131.52:
- Windows: Now catches SystemExit from setuptools while trying to
build the C extension (Issue #41).
- Aditional changes from 184.108.40.206:
- Pool: apply_async now supports a callbacks_propagate keyword
argument that can be a tuple of exceptions to propagate in
callbacks. (callback, errback, accept_callback, timeout_callback).

This would cause normal maxtasksperchild recycled process
to log an error.

without it (Issue #40).

- Update to 22.214.171.124:
* Fixes problem at shutdown when gc has collected symbols.
* Pool now always uses _kill for Py2.5 compatibility on Windows (Issue
* Fixes Python 3 compatibility issues

- Update to 126.96.36.199:
* [Pool] Fix for check_timeouts if not set.
Fix contributed by Dmitry Sukhov
* Fixed pickle problem with Traceback.
Code.frame.__loader__ is now ignored as it may be set to an unpickleable
* The Django old-layout warning was always showing.
188.8.131.52 - 2012-09-26
* Fixes typo
184.108.40.206 - 2012-09-26
* Windows: Fixes for SemLock._rebuild (Issue #24).
* Pool: Job terminated with terminate_job now raises
220.127.116.11 - 2012-09-21
* Windows: Fixes unpickling of SemLock when using fallback.
* Windows: Fixes installation when no C compiler.
18.104.22.168 - 2012-09-20
* Installation now works again for Python 3.
22.214.171.124 - 2012-09-14
* Merged with Python trunk (many authors, many fixes: see Python changelog
* Using execv now also works with older Django projects using setup_environ
* Billiard now installs with a warning that the C extension could not be
built if a compiler is not installed or the build fails in some other way.
It really is recommended to have the C extension installed when running
with force execv, but this change also makes it easier to install.
* Pool: Hard timeouts now sends KILL shortly after TERM so that C extensions
cannot block the signal.
Python signal handlers are called in the interpreter, so they cannot be
called while a C extension is blocking the interpreter from running.
* Now uses a timeout value for Thread.join that doesn't exceed the maximum
on some platforms.
* Fixed bug in the SemLock fallback used when C extensions not installed.
Fix contributed by Mher Movsisyan.
* Pool: Now sets a Process.index attribute for every process in the pool.
This number will always be between 0 and concurrency-1, and can be used
to e.g. create a logfile for each process in the pool without creating a
new logfile whenever a process is replaced.
126.96.36.199 - 2012-08-05
* Fixed Python 2.5 compatibility issue.
* New Pool.terminate_job(pid) to terminate a job without raising
188.8.131.52 - 2012-08-01
* Adds support for FreeBSD 7+
Fix contributed by koobs.
* Pool: New argument allow_restart is now required to enable the pool
process sentinel that is required to restart the pool.
It's disabled by default, which reduces the number of file descriptors/
semaphores required to run the pool.
* Pool: Now emits a warning if a worker process exited with error-code.
But not if the error code is 155, which is now returned if the worker
process was recycled (maxtasksperchild).
* Python 3 compatibility fixes.
* Python 2.5 compatibility fixes.
184.108.40.206 - 2012-06-26
* The TimeLimitExceeded exception string representation only included the
seconds as a number, it now gives a more human friendly description.

220.127.116.11 - 2012-06-03

__main__ module when execv is enabled.

* Can now be installed on Py 3.2
* Issue #12091: simplify ApplyResult and MapResult with threading.Event
Patch by Charles-Francois Natali
* Pool: Support running without TimeoutHandler thread.
* The with_*_thread arguments has also been replaced with a single
* Two new pool callbacks:
* on_timeout_set(job, soft, hard)
Applied when a task is executed with a timeout.
Applied when a timeout is cancelled (the job completed)

threads (TimeoutHandler still not supported)

process had a non-successful exitcode.
* Pool: New options max_restart + max_restart_freq
* Pool: The ``WorkerLostError`` message now includes the exitcode of the
process that disappeared.

- Update to 188.8.131.52
* Now always cleans up after sys.exc_info() to avoid cyclic references.
* ExceptionInfo without arguments now defaults to sys.exc_info.
* Forking can now be disabled using the MULTIPROCESSING_FORKING_DISABLE
Also this envvar is set so that the behavior is inherited after execv.
* The semaphore cleanup process started when execv is used now sets a useful
process name if the setproctitle module is installed.
* Sets the FORKED_BY_MULTIPROCESSING environment variable if forking is

- Update to 184.108.40.206

* Wed Apr 25 2012 firstname.lastname@example.org
- Generate new spec
- Update to 220.127.116.11
* PyPy now falls back to using its internal _multiprocessing module, so
everything works except for forking_enable(False) (which silently degrades)
* Fixed Python 2.5 compat issues.
* Uses more with statements
* Merged some of the changes from the Python 3 branch.

consider py3k support at some point).

* Fri Nov 25 2011 email@example.com
- Update to 0.3.1
* Fixed broken bool evaluation in supervisor. Thanks to jonozzz
The bug originated from a ``a if x else b`` vs. ``x and a or bz``
confusion when porting code to Python 2.4.
* ``ApplyResult._set`` can't delete the result if it's not been accepted.
This also means ``ApplyResult._ack`` needs to delete the result if the job
has been marked ready.
* Added support for accept callbacks.
* Python 2.4 support.
