        "description": "orphanage\n=========\n\nLet child processes in Python suicide if they became orphans.\n\nInstallation\n------------\n\n.. code-block:: bash\n\n    pip install orphanage\n\nDon't forget to put it in ``setup.py`` / ``requirements.txt``.\n\n\nUsage\n-----\n\n.. code-block:: python\n\n    from orphanage import exit_when_orphaned\n\n    exit_when_orphaned()\n\n\nMotivation\n----------\n\nSome application server softwares (e.g. Gunicorn_) work on a multiple-process\narchitect which we call the master-worker model. They must clean up the worker\nprocesses if the master process is stopped, to prevent them from becoming\norphan processes.\n\nIn the gevent-integration scene, the worker processes of Gunicorn poll their\n``ppid`` in an user thread (a.k.a greenlet) to be orphan-aware. But the user\nthread may be hanged once the master process crashed because of the blocked\nwriting on a pipe, the communicating channel between master process and\nworker processes.\n\nWe want to perform this ``ppid`` polling in a real kernel thread. That is the\nintent of this library.\n\n\nPrinciple\n---------\n\nThis library spawns an internal thread to poll the ``ppid`` at regular\nintervals (for now it is one second). Once the ``ppid`` changed, the original\nparent process should be dead and the current process should be orphaned. The\ninternal thread will send ``SIGTERM`` to the current process.\n\nIn the plan, the ``prctl`` & ``SIGHUP`` pattern may be introduced in Linux\nplatforms to avoid from creating threads. For now, the only supported strategy\nis the ``ppid`` polling, for being portable.\n\n\nAlternatives\n------------\n\nCaoE_ is an alternative to this library which developed by the Douban Inc. It\nuses ``prctl`` and a twice-forking pattern. It has a pure Python implementation\nwithout any C extension compiling requirement. If you don't mind to twist the\nprocess tree, that will be a good choice too.\n\n\nContributing\n------------\n\nIf you want to report bugs or request features, please feel free to open\nissues on GitHub_.\n\nOf course, pull requests are always welcome.\n\n.. _Gunicorn: https://github.com/benoitc/gunicorn\n.. _CaoE: https://github.com/douban/CaoE\n.. _GitHub: https://github.com/tonyseek/python-orphanage/issues\n\n.. |Build Status| image:: https://travis-ci.org/tonyseek/python-orphanage.svg?branch=master\n   :target: https://travis-ci.org/tonyseek/python-orphanage\n   :alt: Build Status\n.. |Coverage Status| image:: https://coveralls.io/repos/github/tonyseek/python-orphanage/badge.svg?branch=master\n   :target: https://coveralls.io/github/tonyseek/python-orphanage?branch=master\n   :alt: Coverage Status\n.. |PyPI Version| image:: https://img.shields.io/pypi/v/orphanage.svg\n   :target: https://pypi.org/project/orphanage/\n   :alt: PyPI Version\n\n",
