About

billiard is a fork of the Python 2.7 multiprocessing package. The multiprocessing package itself is a renamed and updated version of R Oudkerk’s pyprocessing package. This standalone variant draws its fixes/improvements from python-trunk and provides additional bug fixes and improvements.

  • 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.

  • Also, it is a fork of the multiprocessing backport package by Christian Heims.

  • It includes the no-execv patch contributed by R. Oudkerk.

  • And the Pool improvements previously located in Celery.

  • Billiard is used in and is a dependency for Celery and is maintained by the Celery team.

The documentation for billiard is available on Read the Docs.
