    2018-03-21T13:53:00Z

    Welcome to aiohttp 3.1 release.

    This is an incremental release, fully backward compatible with aiohttp 3.0.

    But we have added several new features.

    The most visible one is app.add_routes() (an alias for existing app.router.add_routes(). The addition is very important because all aiohttp docs now uses app.add_routes() call in code snippets. All your existing code still do register routes / resource without any warning but you've got the idea for a favorite way: noisy app.router.add_get() is replaced by app.add_routes().

    The library does not make a preference between decorators::

    routes = web.RouteTableDef()

    @routes.get('/') async def hello(request): return web.Response(text="Hello, world")

    app.add_routes(routes)

    and route tables as a list::

    async def hello(request): return web.Response(text="Hello, world")

    app.add_routes([web.get('/', hello)])

    Both ways are equal, user may decide basing on own code taste.

    Also we have a lot of minor features, bug fixes and documentation updates, see below.

    Features

    • Relax JSON content-type checking in the ClientResponse.json() to allow "application/xxx+json" instead of strict "application/json". (#2206)
    • Bump C HTTP parser to version 2.8 (#2730)
    • Accept a coroutine as an application factory in web.run_app and gunicorn worker. (#2739)
    • Implement application cleanup context (app.cleanup_ctx property). (#2747)
    • Make writer.write_headers a coroutine. (#2762)
    • Add tracking signals for getting request/response bodies. (#2767)
    • Deprecate ClientResponseError.code in favor of .status to keep similarity with response classes. (#2781)
    • Implement app.add_routes() method. (#2787)
    • Implement web.static() and RouteTableDef.static() API. (#2795)
    • Install a test event loop as default by asyncio.set_event_loop(). The change affects aiohttp test utils but backward compatibility is not broken for 99.99% of use cases. (#2804)
    • Refactor ClientResponse constructor: make logically required constructor arguments mandatory, drop _post_init() method. (#2820)
    • Use app.add_routes() in server docs everywhere (#2830)
    • Websockets refactoring, all websocket writer methods are converted into coroutines. (#2836)
    • Provide Content-Range header for Range requests (#2844)

    Bugfixes

    • Fix websocket client return EofStream. (#2784)
    • Fix websocket demo. (#2789)
    • Property BaseRequest.http_range now returns a python-like slice when requesting the tail of the range. It's now indicated by a negative value in range.start rather then in range.stop (#2805)
    • Close a connection if an unexpected exception occurs while sending a request (#2827)
    • Fix firing DNS tracing events. (#2841)

    Improved Documentation

    • Change ClientResponse.json() documentation to reflect that it now allows "application/xxx+json" content-types (#2206)
    • Document behavior when cchardet detects encodings that are unknown to Python. (#2732)
    • Add diagrams for tracing request life style. (#2748)
    • Drop removed functionality for passing StreamReader as data at client side. (#2793)
  • Released at March 14, 2018

    2017-10-18T06:33:50Z

    On behalf of aiohttp development team I'm pleased to announce next aiohttp release.

    It contains very long list of new features and bug fixes (see it below).

    Most important changes are:

    • ClientSession supports trust_env parameter for getting proxy configuration from environment variables (disabled by default).
    • New alternatives for filing route table: route table (https://github.com/aio-libs/aiohttp/blob/master/examples/web_srv_route_table.py) and router decorators (https://github.com/aio-libs/aiohttp/blob/master/examples/web_srv_route_deco.py)
    • Request.remote property for accessing to IP of connected client.
    • Support brotli encoding
    • Support websockets compression

    The full list of changes:

    Features

    • Add SSL related params to ClientSession.request (#1128)
    • Make enable_compression work on HTTP/1.0 (#1828)
    • Deprecate registering synchronous web handlers (#1993)
    • Switch to multidict 3.0. All HTTP headers preserve casing now but compared in case-insensitive way. (#1994)
    • Improvement for normalize_path_middleware. Added possibility to handle URLs with query string. (#1995)
    • Use towncrier for CHANGES.txt build (#1997)
    • Implement trust_env=True param in ClientSession. (#1998)
    • Added variable to customize proxy headers (#2001)
    • Implement router.add_routes and router decorators. (#2004)
    • Deprecated BaseRequest.has_body in favor of BaseRequest.can_read_body Added BaseRequest.body_exists attribute that stays static for the lifetime of the request (#2005)
    • Provide BaseRequest.loop attribute (#2024)
    • Make _CoroGuard awaitable and fix ClientSession.close warning message (#2026)
    • Responses to redirects without Location header are returned instead of raising a RuntimeError (#2030)
    • Added get_client, get_server, setUpAsync and tearDownAsync methods to AioHTTPTestCase (#2032)
    • Add automatically a SafeChildWatcher to the test loop (#2058)
    • add ability to disable automatic response decompression (#2110)
    • Add support for throttling DNS request, avoiding the requests saturation when there is a miss in the DNS cache and many requests getting into the connector at the same time. (#2111)
    • Use request for getting access log information instead of message/transport pair. Add RequestBase.remote property for accessing to IP of client initiated HTTP request. (#2123)
    • json() raises a ContentTypeError exception if the content-type does not meet the requirements instead of raising a generic ClientResponseError. (#2136)
    • Make the HTTP client able to return HTTP chunks when chunked transfer encoding is used. (#2150)
    • add append_version arg into StaticResource.url and StaticResource.url_for methods for getting an url with hash (version) of the file. (#2157)
    • Fix parsing the Forwarded header. * commas and semicolons are allowed inside quoted-strings; * empty forwarded-pairs (as in for=_1;;by=_2) are allowed; * non-standard parameters are allowed (although this alone could be easily done in the previous parser). (#2173)
    • Don't require ssl module to run. aiohttp does not require SSL to function. The code paths involved with SSL will only be hit upon SSL usage. Raise RuntimeError if HTTPS protocol is required but ssl module is not present. (#2221)
    • Accept coroutine fixtures in pytest plugin (#2223)
    • Call shutdown_asyncgens before event loop closing on Python 3.6. (#2227)

    • Support verify_ssl, fingerprint, ssl_context and proxy_headers by client.ws_connect. (#2292)
    • Added aiohttp.ClientConnectorSSLError when connection fails due ssl.SSLError (#2294)

    2017-03-20T17:12:02Z

    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

    aiohttp 1.0 release

    2016-09-16T12:31:40Z

    The first officially stable release. We are working hard on aiohttp stability. This release is tagged as 1.0 -- the library is mature enough for this. Backward compatibility with previous releases is kept as usual. Deprecation period is 1.5 years.

    Client

    • Client cookies support was rewritten in backward incompatible manner to split cookies with the same name but belonging to different domains #1173
    • ProxyConnector is deprecated, regular methods like ClientSession.get() accepts proxy and proxy_auth parameters explicitly #998
    • Default settings for aiohttp.TCPConnector uses asynchronous DNS requests and cache for given DNS resolutions #1152

    Server

    • Router has handy methods for route adding like app.router.add_get(), app.router.add_post() etc. #986

    Major aiohttp release.

    Added support for async for and async with, e.g.

    async with client.get(url) as resp:
        async for line in resp.content:
            print(line)
    

    auto-closes response object and iterates over response's content.

    Server-side signals added (allows, for example, setup http headers for long-living responses in signal hook).

    Python 3.3 support dropped.

    Full list of changes is pretty huge:

    Changes

    • Use errors.HttpProcessingError.message as HTTP error reason and message #459

    • Optimize cythonized multidict a bit

    • Change repr's of multidicts and multidict views

    • default headers in ClientSession are now case-insensitive

    • Make '=' char and 'wss://' schema safe in urls #477

    • ClientResponse.close() forces connection closing by default from now #479 N.B. Backward incompatible change: was .close(force=False) Usingforceparameter for the method is deprecated: use.release()` instead.

    • Properly requote URL's path #480

    • add skip_auto_headers parameter for client API #486

    • Properly parse URL path in aiohttp.web.Request #489

    • Drop ClientResponse.message attribute, it was always implementation detail.

    • Streams are optimized for speed and mostly memory in case of a big HTTP message sizes #496

    • Fix a bug for server-side cookies for dropping cookie and setting it again without Max-Age parameter.

    • Don't trim redirect URL in client API #499

    • Extend precision of access log "D" to milliseconds #527

    • Deprecate StreamResponse.start() method in favor of StreamResponse.prepare() coroutine #525

      .start() is still supported but responses begun with .start() doesn't call signal for response preparing to be sent.

    • Add StreamReader.__repr__

    • Drop Python 3.3 support, from now minimal required version is Python 3.4.1 #541

    • Add async with support for ClientSession.request() and family #536

        try:
            text = await resp.read()
            return text
        finally:
            await resp.release()

    I am happy to announce new release of aiohttp. We did a lot of performance optimizations for new release. It should be 50-70% faster in raw performance than previous version. Numbers look very cool, but for those who uses aiohttp in production situation slightly different, it won't give more than 1-2% of performance increase.

    aiohttp now supports client side websockets. Server side websockets support has been refactored. I think web sockets api is stable now. Also we introduced new multipart system, client side for now but we are working on server side integration as well. New version of aiohttp now supports Except header out of box. Thanks all contributors for hard work!

    aiohttp 0.14 release

    2015-01-15T20:55:03Z

    0.14 is the great release.

    We have finished a hard work to stabilize aiohttp.web now.

    Almost any new wish appeared in our mind may be implemented with the current code by third-party libraries: CORS, sessions, authorization, rendering and so on without the need for making changes in aiohttp itself.

    That's a very strong sign on aiohttp.web design: the library is good and it is as tiny as possible.

    0.14.0 (15/01/2014)

    • HttpMessage._add_default_headers does not overwrite existing headers #216

    • Expose multidict classes at package level

    • add aiohttp.web.WebSocketResponse

    • According to RFC 6455 websocket subprotocol preference order is provided by client, not by server

    • websocket's ping and pong accept optional message parameter

    • multidict views do not accept getall parameter anymore, it returns the full body anyway.

    • multidicts have optional Cython optimization, cythonized version of multidicts is about 5 times faster than pure Python.

    • multidict.getall() returns list, not tuple.

    • Backward imcompatible change: now there are two mutable multidicts (MultiDict, CIMultiDict) and two immutable multidict proxies (MultiDictProxy and CIMultiDictProxy). Previous edition of multidicts was not a part of public API BTW.

    • Router refactoring to push Not Allowed and Not Found in middleware processing

    • Convert ConnectionError to aiohttp.DisconnectedError and don't eat ConnectionError exceptions from web handlers.

    • Remove hop headers from Response class, wsgi response still uses hop headers.

    • Allow to send raw chunked encoded response.

    • Allow to encode output bytes stream into chunked encoding.

    • Allow to compress output bytes stream with deflate encoding.

    • Server has 75 seconds keepalive timeout now, was non-keepalive by default.

    • Application doesn't accept **kwargs anymore (#243).

    • Request is inherited from dict now for making per-request storage to middlewares (#242).

    • According to RFC 6455 websocket subprotocol preference order is provided by client, not by server

    • websocket's ping and pong accept optional message parameter

    • multidict views do not accept getall parameter anymore, it returns the full body anyway.

    • multidicts have optional Cython optimization, cythonized version of multidicts is about 5 times faster than pure Python.

    • multidict.getall() returns list, not tuple.

    • Backward imcompatible change: now there are two mutable multidicts (MultiDict, CIMultiDict) and two immutable multidict proxies (MultiDictProxy and CIMultiDictProxy). Previous edition of multidicts was not a part of public API BTW.

    • Router refactoring to push Not Allowed and Not Found in middleware processing

    • Convert ConnectionError to aiohttp.DisconnectedError and don't eat ConnectionError exceptions from web handlers.

    • Remove hop headers from Response class, wsgi response still uses hop headers.

    • Allow to send raw chunked encoded response.

    • Allow to encode output bytes stream into chunked encoding.

    • Allow to compress output bytes stream with deflate encoding.

    • Server has 75 seconds keepalive timeout now, was non-keepalive by default.

    • Application doesn't accept **kwargs anymore (#243).

    • Request is inherited from dict now for making per-request storage to middlewares (#242).
