Changelog | gipc @ PyPI | gipc @ GitHub

Overview

gipc enables reliable child process management and non-blocking inter-process communication in software that uses gevent.

Using Python's multiprocessing package in the context of a codebase that also uses gevent is error-prone and may break the application in various subtle ways. With gipc, multiprocessing.Process-based child processes can again safely be created in your gevent-powered application. The API of multiprocessing.Process objects is provided in a gevent-cooperative way. Also, gipc provides a pipe-based transport layer for gevent-cooperative inter-greenlet and inter-process communication. gipc is lightweight and easy to integrate.

From 2012 to 2018, gipc's home was at bitbucket.org/jgehrcke/gipc. Since then development has continued on GitHub.

Platform support

The current version of gipc works on CPython 3.8 through 3.12. It supports gevent versions 1.5 and newer and supports both, Unix-like systems as well as Windows. On Linux and macOS, gipc also works with PyPy.

gipc's continuous integration (CI) pipeline automatically executes a wide range of tests on Linux, Darwin (macOS), and Windows.
