gipc 1.3.0

gevent-cooperative child processes and inter-process communication.

Changelog | gipc @ PyPI | gipc @ GitHub

CI status (master branch):

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

Overview

gipc (pronunciation as in “gipsy”) provides reliable child process management and non-blocking inter-process communication in the context of 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 safely be created anywhere within 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.

Code examples

Individual example programs can be found in the examples directory.
