execnet: distributed Python deployment and communication

Important

execnet currently is in maintenance-only mode, mostly because it is still the backend of the pytest-xdist plugin. Do not use in new projects.

execnet provides carefully tested means to ad-hoc interact with Python interpreters across version, platform and network barriers. It provides a minimal and fast API targetting the following uses:

• distribute tasks to local or remote processes
• write and deploy hybrid multi-process applications
• write scripts to administer multiple hosts

Features

• zero-install bootstrapping: no remote installation required!
• flexible communication: send/receive as well as callback/queue mechanisms supported
• simple serialization of python builtin types (no pickling)
• grouped creation and robust termination of processes
• well tested between CPython 2.7, 3.4+, Jython 2.5.1 and PyPy 2.2 interpreters.
• interoperable between Windows and Unix-ish systems.
• integrates with different threading models, including standard os threads, eventlet and gevent based systems.
