Installation and Requirements, gevent runs on Python 2.7.9 and up, and Python 3.5, 3.6, 3.7 and 3.8. gevent requires the greenlet library and will install the cffi library by default on Windows. Who is using Greenlet? There are several libraries that use Greenlet as a more flexible alternative to Python's built in coroutine support: Concurrence; Eventlet; Gevent; Getting Greenlet. The easiest way to get Greenlet is to install it with pip or easy_install: pip install greenlet easy_install greenlet

Introduction, That way even the modules that are unaware of gevent can benefit from running in a multi-greenlet environment. >>> from gevent import monkey; monkey. If you want to use gevent you will need to use a gevent based WSGI server. The simple built-in development server will not run in a gevent loop. The simple built-in development server will not run in a gevent loop.
What is gevent?, (for I/O benefits) and this is where greenlets fits into the picture. Pre-1.0 version, gevent is based on libevent; and from 1.0 onwards, gevent is based on libev. gevent.Greenlet instance. gevent.event.Event instance. gevent.lock.Semaphore instance. gevent.subprocess.Popen instance. If objects is None (the default), wait() blocks until the current event loop has nothing to do (or until timeout passes): all greenlets have finished. all servers were stopped. all event loop watchers were stopped.

This gevent.pywsgi – A pure-Python, gevent-friendly WSGI server¶ The server is provided in WSGIServer, but most of the actual WSGI work is handled by WSGIHandler — a new instance is created for each request. The server can be customized to use different subclasses of WSGIHandler.
gevent · PyPI, pywsgi – A pure-Python, gevent-friendly WSGI server¶. The server is provided in WSGIServer , but most of the actual WSGI work is handled by WSGIHandler — a gevent.wsgi was deprecated for years and was finally removed in gevent 1.3. There's an open bottle bug for this problem. Some of your options are: Use a different WSGI server. You can directly use gevents wsgi server with python -m gevent.pywsgi my_module:my_app. Or try gunicorn; Downgrade to an older gevent

greenlet · PyPI, pip install greenlet easy_install greenlet. Source code archives and windows installers are available on the python package index at https://pypi.python.org/pypi/ Project description. The greenlet package is a spin-off of Stackless, a version of CPython that supports micro-threads called “tasklets”. Tasklets run pseudo-concurrently (typically in a single or a few OS-level threads) and are synchronized with data exchanges on “channels”. A “greenlet”, on the other hand, is a still more primitive notion of micro-thread with no implicit scheduling; coroutines, in other words.
