aiohttp 2.0 release!
--------------------
For this release we completely refactored low-level implementation of http handling.
Finally `uvloop` gives performance improvement. Overall performance improvement
should be around 70-90% compared to 1.x version.
We took opportunity to refactor long standing api design problems across whole package.
Client exceptions handling has been cleaned up and now much more straight forward. Client payload
management simplified and allows to extend with any custom type. Client connection pool
implementation has been redesigned as well, now there is no need for actively releasing response objects,
aiohttp handles connection release automatically.
Another major change, we moved aiohttp development to public organization https://github.com/aio-libs
With this amount of api changes we had to make backward incompatible changes. Please check this migration document http://aiohttp.readthedocs.io/en/latest/migration.html
Please report problems or annoyance with with api to https://github.com/aio-libs/aiohttp
Features
--------
- Supports both client and server side of HTTP protocol.
- Supports both client and server Web-Sockets out-of-the-box.
- Web-server has middlewares and pluggable routing.
Getting started
---------------
Client
^^^^^^
To retrieve something from the web:
.. code-block:: python
import aiohttp
import asyncio
async def fetch(session, url):
with aiohttp.Timeout(10, loop=session.loop):
async with session.get(url) as response:
return await response.text()
async def main(loop):
async with aiohttp.ClientSession(loop=loop) as session:
html = await fetch(session, 'http://python.org')
print(html)
if __name__ == '__main__':
loop = asyncio.get_event_loop()
loop.run_until_complete(main(loop))
Server
^^^^^^
This is simple usage example:
.. code-block:: python
from aiohttp import web
async def handle(request):
name = request.match_info.get('name', "Anonymous")
text = "Hello, " + name
return web.Response(text=text)
async def wshandler(request):
ws = web.WebSocketResponse()
await ws.prepare(request)
async for msg in ws:
if msg.type == web.MsgType.text:
await ws.send_str("Hello, {}".format(msg.data))
elif msg.type == web.MsgType.binary:
await ws.send_bytes(msg.data)
elif msg.type == web.MsgType.close:
break
return ws
app = web.Application()
app.router.add_get('/echo', wshandler)
app.router.add_get('/', handle)
app.router.add_get('/{name}', handle)
web.run_app(app)
Note: examples are written for Python 3.5+ and utilize PEP-492 aka
async/await. If you are using Python 3.4 please replace ``await`` with
``yield from`` and ``async def`` with ``@coroutine`` e.g.::
async def coro(...):
ret = await f()
should be replaced by::
@asyncio.coroutine
def coro(...):
ret = yield from f()

Changes
=======
2.1.0 (2017-05-26)
------------------
- Added support for experimental `async-tokio` event loop written in Rust
https://github.com/PyO3/tokio
- Write to transport ``\r\n`` before closing after keepalive timeout,
otherwise client can not detect socket disconnection. #1883
- Only call `loop.close` in `run_app` if the user did *not* supply a loop.
Useful for allowing clients to specify their own cleanup before closing the
asyncio loop if they wish to tightly control loop behavior
- Content disposition with semicolon in filename #917
- Added `request_info` to response object and `ClientResponseError`. #1733
- Added `history` to `ClientResponseError`. #1741
- Allow to disable redirect url re-quoting #1474
- Handle RuntimeError from transport #1790
- Dropped "%O" in access logger #1673
- Added `args` and `kwargs` to `unittest_run_loop`. Useful with other
decorators, for example `@patch`. #1803
- Added `iter_chunks` to response.content object. #1805
- Avoid creating TimerContext when there is no timeout to allow
compatibility with Tornado. #1817 #1180
- Add `proxy_from_env` to `ClientRequest` to read from environment
variables. #1791
- Add DummyCookieJar helper. #1830
- Fix assertion errors in Python 3.4 from noop helper. #1847
- Do not unquote `+` in match_info values #1816
- Use Forwarded, X-Forwarded-Scheme and X-Forwarded-Host for better scheme and
host resolution. #1134
- Fix sub-application middlewares resolution order #1853
- Fix applications comparison #1866
- Fix static location in index when prefix is used #1662
- Make test server more reliable #1896
- Use Forwarded, X-Forwarded-Scheme and X-Forwarded-Host for better scheme and
host resolution. #1134
- Extend list of web exceptions, add HTTPUnprocessableEntity,
HTTPFailedDependency, HTTPInsufficientStorage status codes #1920
2.0.7 (2017-04-12)

passed #1786

2.0.0 (2017-03-20)
------------------

e.g. for socket-based activated applications, when binding of a socket is
done by the parent process.
