execnet 1.7.0

execnet: rapid multi-Python deployment

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.
