Cooperative multitasking and i/o for Python
Evergreen is a cooperative multitasking and i/o library for Python. It provides equivalent primitives to those for thread programming, but uses a cooperative model instead.
Operations are driven by an event loop which will run the given tasks and i/o operations in a non-blocking manner while presenting the user a synchronous, blocking API.
Cooperative synchronization primitives: locks, events, queues, channels
Futures API (almost) compatible with the standard library
Cooperative versions of several standard library modules
Ability to monkey patch standard library modules to make them cooperative
Running the test suite
There are several ways of running the test suite:
Running individual tests:
Go inside the tests/ directory and run each individual test
Run the test with the current Python interpreter:
From the toplevel directory, run: nosetests -v -w tests/
Use Tox to run the test suite in several virtualenvs with several interpreters
From the toplevel directory, run: tox -e py26,py27,py32, py33 this will run the test suite on Python 2.6, 2.7, 3.2 and 3.3 (you’ll need to have them installed beforehand)
Unless stated otherwise on-file Evergreen uses the MIT license, check LICENSE and NOTICE files.
