When you were running multiple applications using asyncio, sanic must be closed as the latest order because it closes the loop. The patch limits the behavior only when sanic created its own loop by argument `loop=None`.
Sanic
=================================
|Join the chat at https://gitter.im/sanic-python/Lobby| |Build Status| |PyPI| |PyPI version|
Sanic is a Flask-like Python 3.5+ web server that's written to go fast. It's based on the work done by the amazing folks at magicstack, and was inspired by `this article <https://magic.io/blog/uvloop-blazing-fast-python-networking/>`_.
On top of being Flask-like, Sanic supports async request handlers. This means you can use the new shiny async/await syntax from Python 3.5, making your code non-blocking and speedy.
Sanic is developed `on GitHub <https://github.com/channelcat/sanic/>`_. Contributions are welcome!
Benchmarks
----------
All tests were run on an AWS medium instance running ubuntu, using 1
process. Each script delivered a small JSON response and was tested with
wrk using 100 connections. Pypy was tested for Falcon and Flask but did
not speed up requests.

| Server | Implementation | Requests/sec | Avg Latency |
+===========+=======================+================+===============+
| Sanic | Python 3.5 + uvloop | 33,342 | 2.96ms |

Hello World Example
-------------------
.. code:: python
from sanic import Sanic
from sanic.response import json
app = Sanic()
@app.route("/")
async def test(request):
return json({"hello": "world"})
if __name__ == "__main__":
app.run(host="0.0.0.0", port=8000)
SSL Example
-----------
Optionally pass in an SSLContext:
.. code:: python
import ssl
certificate = "/path/to/certificate"
keyfile = "/path/to/keyfile"
context = ssl.create_default_context(purpose=ssl.Purpose.CLIENT_AUTH)
context.load_cert_chain(certificate, keyfile=keyfile)
app.run(host="0.0.0.0", port=8443, ssl=context)
Installation
------------
- ``python -m pip install sanic``
Documentation
-------------
Documentation can be found in the ``docs`` directory.

TODO
----
* Streamed file processing
* File output
* Examples of integrations with 3rd-party modules
* RESTful router
Limitations
-----------
* No wheels for uvloop and httptools on Windows :(
