asyncio event loop scheduling callbacks in eventlet.
* Trollius project: http://trollius.readthedocs.org/
* aiogreen at PyPI: https://pypi.python.org/pypi/aiogreen
Installation
============
Requirements:
- eventlet 0.14 or newer
- asyncio or trollius:
* Python 3.4 and newer: asyncio is now part of the stdlib
* Python 3.3: need Tulip 0.4.1 or newer (pip install asyncio)
* Python 2.6-3.2: need trollius 1.0 or newer (pip install trollius)
Type::
pip install aiogreen
or::
python setup.py install
Run tests
=========
Run tests with tox
------------------
The `tox project <https://testrun.org/tox/latest/>`_ can be used to build a
virtual environment with all runtime and test dependencies and run tests
against different Python versions (2.6, 2.7, 3.2, 3.3).
For example, to run tests with Python 2.7, just type::
tox -e py27
To run tests against other Python versions:
* ``py26``: Python 2.6
* ``py27``: Python 2.7
* ``py27_patch``: Python 2.7 with eventlet monkey patching
* ``py32``: Python 3.2
* ``py33``: Python 3.3
* ``py34``: Python 3.4
Run tests manually
------------------
Run the following command from the directory of the aiogreen project:
python runtests.py -r
Changelog
=========
Version 0.2 (development version)
---------------------------------
* Support also eventlet 0.14, not only eventlet 0.15 or newer
* Support eventlet with monkey-patching
* Rewrite the code handling file descriptors to ensure that the listener is
only called once per loop iteration, to respect asyncio specification.
* Simplify the loop iteration: remove custom code to reuse instead the
asyncio/trollius code (_run_once)
* Reuse call_soon, call_soon_threadsafe, call_at, call_later from
asyncio/trollius, remove custom code
* sock_connect() is now asynchronous
* Add a suite of automated unit tests
* Fix EventLoop.stop(): don't stop immediatly, but schedule stopping the event
loop with call_soon()
* Add tox.ini to run tests with tox
2014-11-19: version 0.1
-----------------------
* First public release
Implemented
===========
Methods:
* call_at()
* call_later()
* call_soon()
* run_forever()
* run_in_executor()
* run_until_complete()
* create_connection(): TCP client
* stop()
* coroutines and tasks
Tests of aiogreen 0.1:
* Tested on Python 2.7, 3.3 and 3.5
* Tested on Linux and Windows
* Tested with Trollius 1.0, 1.0.1 and 1.0.2
* Tested with asyncio 0.4.1 and 3.4.2
To do (Not supported)
=====================
* run an event loop in a thread different than the main thread
* sockets: create_server, sock_recv
* pipes: connect_read_pipe
* subprocesses: need pipes
* signal handlers: add_signal_handler (only for pyevent hub?)
* tox.ini: add py33_patch. eventlet with Python 3 and monkey-patch causes
an issue in importlib.
eventlet and Python 3
