Subject: [PATCH 003/603] [3.6] Use version: ~> 1.0, remove conditions: v1
 (#4162) (#4166)

The version requirement `= 0` advertised in early development stages was an unfortunate choice, as this is going to be the opt-out once the new build config validation feature will be rolled out further. Please use `~> 1.0` instead.

The conditions version `v1` is now the default, so this key can be removed.

Subject: [PATCH 005/603] [3.6] Don't use docstring in tests. (#4163) (#4168)

1. Test code is not a part of public API
2. Test runners displays test docstring instead of test function if present,
   it complicates the code navigation, e.g. opening a failed test in editor etc..

    ``aiohttp.GunicornUVLoopWebWorker`` worker class.
 
+Proxy through NGINX
+----------------------
+
+We can proxy our gunicorn workers through NGINX with a configuration like this:
+
+.. code-block:: nginx
+
+    worker_processes 1;
+    user nobody nogroup;
+    events {
+        worker_connections 1024;
+    }
+    http {
+        ## Main Server Block
+        server {
+            ## Open by default.
+            listen                80 default_server;
+            server_name           main;
+            client_max_body_size  200M;
+
+            ## Main site location.
+            location / {
+                proxy_pass                          http://127.0.0.1:8080;
+                proxy_set_header                    Host $host;
+                proxy_set_header X-Forwarded-Host   $server_name;
+                proxy_set_header X-Real-IP          $remote_addr;
+            }
+        }
+    }
+
+Since gunicorn listens for requests at our localhost address on port 8080, we can 
+use the `proxy_pass <https://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_pass>`_ 
+directive to send web traffic to our workers. If everything is configured correctly,
+we should reach our application at the ip address of our web server.
+
+Proxy through NGINX + SSL
+----------------------------
+
+Here is an example NGINX configuration setup to accept SSL connections:
+
+.. code-block:: nginx
+
+    worker_processes 1;
+    user nobody nogroup;
+    events {
+        worker_connections 1024;
+    }
+    http {
+        ## SSL Redirect
+        server {
+            listen 80       default;
+            return 301      https://$host$request_uri;
+        }
+
+        ## Main Server Block
+        server {
+            # Open by default.
+            listen                443 ssl default_server;
+            listen                [::]:443 ssl default_server;
+            server_name           main;
+            client_max_body_size  200M;
+
+            ssl_certificate       /etc/secrets/cert.pem;
+            ssl_certificate_key   /etc/secrets/key.pem;
+
+            ## Main site location.
+            location / {
+                proxy_pass                          http://127.0.0.1:8080;
+                proxy_set_header                    Host $host;
+                proxy_set_header X-Forwarded-Host   $server_name;
+                proxy_set_header X-Real-IP          $remote_addr;
+            }
+        }
+    }
+  
+
+The first server block accepts regular http connections on port 80 and redirects
+them to our secure SSL connection. The second block matches our previous example
+except we need to change our open port to https and specify where our SSL 
+certificates are being stored with the ``ssl_certificate`` and ``ssl_certificate_key``
+directives.
+
+During development, you may want to `create your own self-signed certificates for testing purposes <https://www.digitalocean.com/community/tutorials/how-to-create-a-self-signed-ssl-certificate-for-nginx-in-ubuntu-18-04>`_
+and use another service like `Let's Encrypt <https://letsencrypt.org/>`_ when you
+are ready to move to production.

Subject: [PATCH 018/603] Backport fix of noop in least invasive way (#4213)

The coroutine-style definition of noop causes a warning on Python 3.8.

On master, it has been fixed and noop2 removed. This is the least invasive
way to get rid of the warning in 3.6.

+
+
+The aiohttp Request Lifecycle
+=============================
+
+
+Why is aiohttp client API that way?
+--------------------------------------
+
+
+The first time you use aiohttp, you'll notice that a simple HTTP request is performed not with one, but with up to three steps:
+
+
+.. code-block:: python
+
+
+    async with aiohttp.ClientSession() as session:
+        async with session.get('http://python.org') as response:
+            print(await response.text())
+
+
+It's especially unexpected when coming from other libraries such as the very popular :term:`requests`, where the "hello world" looks like this:
+
+
+.. code-block:: python
+
+
+    response = requests.get('http://python.org')
+    print(response.text())
+
+
+So why is the aiohttp snippet so verbose?
+
+
+Because aiohttp is asynchronous, its API is designed to make the most out of non-blocking network operations. In a code like this, requests will block three times, and does it transparently, while aiohttp gives the event loop three opportunities to switch context:
+
+
+- When doing the ``.get()``, both libraries send a GET request to the remote server. For aiohttp, this means asynchronous I/O, which is here marked with an ``async with`` that gives you the guaranty that not only it doesn't block, but that it's cleanly finalized.
+- When doing ``response.text`` in requests, you just read an attribute. The call to ``.get()`` already preloaded and decoded the entire response payload, in a blocking manner. aiohttp loads only the headers when ``.get()`` is executed, letting you decide to pay the cost of loading the body afterward, in a second asynchronous operation. Hence the ``await response.text()``.
+- ``async with aiohttp.ClientSession()`` does not perform I/O when entering the block, but at the end of it, it will ensure all remaining resources are closed correctly. Again, this is done asynchronously and must be marked as such. The session is also a performance tool, as it manages a pool of connections for you, allowing you to reuse them instead of opening and closing a new one at each request. You can even `manage the pool size by passing a connector object <client_advanced.html#limiting-connection-pool-size>`_.
+
+Using a session as a best practice
+-----------------------------------
+
+The requests library does in fact also provides a session system. Indeed, it lets you do:
+
+.. code-block:: python
+
+    with requests.session() as session:
+        response = session.get('http://python.org')
+        print(response.text)
+
+It just not the default behavior, nor is it advertised early in the documentation. Because of this, most users take a hit in performances, but can quickly start hacking. And for requests, it's an understandable trade-off, since its goal is to be "HTTP for humans" and simplicity has always been more important than performance in this context.
+
+However, if one uses aiohttp, one chooses asynchronous programming, a paradigm that makes the opposite trade-off: more verbosity for better performances. And so the library default behavior reflects this, encouraging you to use performant best practices from the start.
+
+How to use the ClientSession ?
+-------------------------------
+
+By default the :class:`aiohttp.ClientSession` object will hold a connector with a maximum of 100 connections, putting the rest in a queue. This is quite a big number, this means you must be connected to a hundred different servers (not pages!) concurrently before even having to consider if your task needs resource adjustment.
+
+In fact, you can picture the session object as a user starting and closing a browser: it wouldn't make sense to do that every time you want to load a new tab.
+
+So you are expected to reuse a session object and make many requests from it. For most scripts and average-sized softwares, this means you can create a single session, and reuse it for the entire execution of the program. You can even pass the session around as a parameter in functions. E.G, the typical "hello world":
+
+.. code-block:: python
+
+    import aiohttp
+    import asyncio
+
+    async def main():
+        async with aiohttp.ClientSession() as session:
+            async with session.get('http://python.org') as response:
+                html = await response.text()
+                print(html)
+
+    loop = asyncio.get_event_loop()
+    loop.run_until_complete(main())
+
+
+Can become this:
+
+
+.. code-block:: python
+
+    import aiohttp
+    import asyncio
+
+    async def fetch(session, url):
+        async with session.get(url) as response:
+            return await response.text()
+
+    async def main():
+        async with aiohttp.ClientSession() as session:
+            html = await fetch(session, 'http://python.org')
+            print(html)
+
+    loop = asyncio.get_event_loop()
+    loop.run_until_complete(main())
+
+On more complex code bases, you can even create a central registry to hold the session object from anywhere in the code, or a higher level ``Client`` class that holds a reference to it.
+
+When to create more than one session object then? It arises when you want more granularity with your resources management:
+
+- you want to group connections by a common configuration. E.G: sessions can set cookies, headers, timeout values, etc. that are shared for all connections they holds.
+- you need several threads and want to avoid sharing a mutable object between them.
+- you want several connection pools to benefit from different queues and assign priorities. E.G: one session never uses the queue and is for high priority requests, the other one has a small concurrency limit and a very long queue, for non important requests.

+Cookie Quoting Routine
+^^^^^^^^^^^^^^^^^^^^^^
+
+The client uses the :class:`~aiohttp.SimpleCookie` quoting routines
+conform to the :rfc:`2109`, which in turn references the character definitions
+from :rfc:`2068`. They provide a two-way quoting algorithm where any non-text
+character is translated into a 4 character sequence: a forward-slash
+followed by the three-digit octal equivalent of the character.
+Any ``\`` or ``"`` is quoted with a preceding ``\`` slash.
+Because of the way browsers really handle cookies (as opposed to what the RFC
+says) we also encode ``,`` and ``;``.
+
+Some backend systems does not support quoted cookies. You can skip this
+quotation routine by passing ``quote_cookie=False`` to the
+:class:`~aiohttp.CookieJar` constructor::
+
+   jar = aiohttp.CookieJar(quote_cookie=False)

Subject: [PATCH 213/603] Fix HEAD requests for static content (#4813)

* Fix HEAD requests for static content

FileResponse directly injects the response into the socket with
sendfile() (if it can), which bypasses the checks in Response that
prevent any content being sent for HEAD requests and for 204 (No
Content) and 304 (Not Modified) responses. I've duplicated that logic
into FileResponse. I'm not sure if the status checks are actually
applicable (since StaticResource already has its own handling for Not
Modified) and I don't currently have any tests for them.

Closes #4809.

Subject: [PATCH 232/603] Fix OverflowError with 32-bit (signed) time_t (#4873)

Fix the package to work on 32-bit platforms (i386, arm) that use 32-bit
signed time_t.  This means changing TestCookieJarSafe.test_expires() to
use an earlier arbitrary date, and adjusting CookieJar to use MAX_TIME
that fits in time_t.

For the latter purpose, we try to convert datetime.max into timestamp
and if it fails, we make date from a timestamp matching max unsigned
int32.  This is far from perfect but apparently there's no trivial way
of getting max time_t value from inside Python, and it should cover all
the common platforms.

Fixes #4515

Subject: [PATCH 235/603] Fix HttpPayloadParser dealing with chunked response
 (#4630)  (#4846)

* Parse the last CRLF of chunked response correctly (#4630)

If the last CRLF or only the LF are received via separate TCP segment,
HTTPPayloadParser misjudges that trailers should come after 0\r\n in the
chunked response body.

In this case, HttpPayloadParser starts waiting for trailers, but the only
remaining data to be received is CRLF. Thus, HttpPayloadParser waits trailers
indefinitely and this incurs TimeoutError in user code.

However, if the connection is keep alive disabled, this problem is not
reproduced because the server shutdown the connection explicitly after sending
all data. If the connection is closed .feed_eof is called and it helps
HttpPayloadParser finish its waiting.

+Peer disconnection
+------------------
 
-Web Handler Cancellation
-------------------------
-
-.. warning::
-
-   :term:`web-handler` execution could be canceled on every ``await``
-   if client drops connection without reading entire response's BODY.
-
-   The behavior is very different from classic WSGI frameworks like
-   Flask and Django.
-
-Sometimes it is a desirable behavior: on processing ``GET`` request the
-code might fetch data from database or other web resource, the
-fetching is potentially slow.
-
-Canceling this fetch is very good: the peer dropped connection
-already, there is no reason to waste time and resources (memory etc) by
-getting data from DB without any chance to send it back to peer.
-
-But sometimes the cancellation is bad: on ``POST`` request very often
-is needed to save data to DB regardless to peer closing.
-
-Cancellation prevention could be implemented in several ways:
-
-* Applying :func:`asyncio.shield` to coroutine that saves data into DB.
-* Spawning a new task for DB saving
-* Using aiojobs_ or other third party library.
-
-:func:`asyncio.shield` works pretty good. The only disadvantage is you
-need to split web handler into exactly two async functions: one
-for handler itself and other for protected code.
-
-For example the following snippet is not safe::
-
-   async def handler(request):
-       await asyncio.shield(write_to_redis(request))
-       await asyncio.shield(write_to_postgres(request))
-       return web.Response(text='OK')
-
-Cancellation might be occurred just after saving data in REDIS,
-``write_to_postgres`` will be not called.
-
-Spawning a new task is much worse: there is no place to ``await``
-spawned tasks::
-
-   async def handler(request):
-       request.loop.create_task(write_to_redis(request))
-       return web.Response(text='OK')
-
-In this case errors from ``write_to_redis`` are not awaited, it leads
-to many asyncio log messages *Future exception was never retrieved*
-and *Task was destroyed but it is pending!*.
-
-Moreover on :ref:`aiohttp-web-graceful-shutdown` phase *aiohttp* don't
-wait for these tasks, you have a great chance to loose very important
-data.
-
-On other hand aiojobs_ provides an API for spawning new jobs and
-awaiting their results etc. It stores all scheduled activity in
-internal data structures and could terminate them gracefully::
-
-   from aiojobs.aiohttp import setup, spawn
-
-   async def coro(timeout):
-       await asyncio.sleep(timeout)  # do something in background
-
-   async def handler(request):
-       await spawn(request, coro())
-       return web.Response()
-
-   app = web.Application()
-   setup(app)
-   app.router.add_get('/', handler)
-
-All not finished jobs will be terminated on
-:attr:`Application.on_cleanup` signal.
+When a client peer is gone a subsequent reading or writing raises :exc:`OSError`
+or more specific exception like :exc:`ConnectionResetError`.
 
-To prevent cancellation of the whole :term:`web-handler` use
-``@atomic`` decorator::
+The reason for disconnection is vary; it can be a network issue or explicit
+socket closing on the peer side without reading the whole server response.
 
-   from aiojobs.aiohttp import atomic
+*aiohttp* handles disconnection properly but you can handle it explicitly, e.g.::
 
-   @atomic
    async def handler(request):
-       await write_to_db()
-       return web.Response()
-
-   app = web.Application()
-   setup(app)
-   app.router.add_post('/', handler)
-
-It prevents all ``handler`` async function from cancellation,
-``write_to_db`` will be never interrupted.
-
-.. _aiojobs: http://aiojobs.readthedocs.io/en/latest/

+Fix keepalive connections not being closed in time
+
+Refactoring in 964921d4e97e7c84bcfda6772ed458549aea0b09 introduced a
+regression so that `_cleanup()` could be called only once or few times.
+`_release()` expects `self._cleanup_handle` to be None to add new
+`weakref_handle`. But when `_cleanup()` called and there are no
+remaining connections, `self._cleanup_handle` will remain as
+`<TimerHandle cancelled when=5853434>`, so `_release()` will not have a
+chance to schedule `_cleanup()` call again.

+   *aiohttp* **ceils** timeout if the value is equal or greater than 5
+   seconds. The timeout expires at the next integer second greater than
+   ``current_time + timeout``.
+
+   The ceiling is done for the sake of optimization, when many concurrent tasks
+   are scheduled to wake-up at the almost same but different absolute times. It
+   leads to very many event loop wakeups, which kills performance.
+
+   The optimization shifts absolute wakeup times by scheduling them to exactly
+   the same time as other neighbors, the loop wakes up once-per-second for
+   timeout expiration.
+
+   Smaller timeouts are not rounded to help testing; in the real life network
+   timeouts usually greater than tens of seconds.

 - When doing ``response.text`` in requests, you just read an attribute. The call to ``.get()`` already preloaded and decoded the entire response payload, in a blocking manner. aiohttp loads only the headers when ``.get()`` is executed, letting you decide to pay the cost of loading the body afterward, in a second asynchronous operation. Hence the ``await response.text()``.
 - ``async with aiohttp.ClientSession()`` does not perform I/O when entering the block, but at the end of it, it will ensure all remaining resources are closed correctly. Again, this is done asynchronously and must be marked as such. The session is also a performance tool, as it manages a pool of connections for you, allowing you to reuse them instead of opening and closing a new one at each request. You can even `manage the pool size by passing a connector object <client_advanced.html#limiting-connection-pool-size>`_.

And for requests, it's an understandable trade-off, since its goal is to be "HTTP for humans" and simplicity has always been more important than performance in this context.
 
-However, if one uses aiohttp, one chooses asynchronous programming, a paradigm that makes the opposite trade-off: more verbosity for better performances. And so the library default behavior reflects this, encouraging you to use performant best practices from the start.

-Why is Python 3.5.3 the lowest supported version?
--------------------------------------------------
-
-Python 3.5.2 fixes the protocol for async iterators: ``__aiter__()`` is
-not a coroutine but a regular function.
-
-Python 3.5.3 has a more important change: :func:`asyncio.get_event_loop`
-returns the running loop instance if called from a coroutine.
-Previously it returned a *default* loop, set by
-:func:`asyncio.set_event_loop`.
-
-Previous to Python 3.5.3,
-:func:`asyncio.get_event_loop` was not reliable, so users were
-forced to explicitly pass the event loop instance everywhere.
-If a future object were created for one event loop
-(e.g. the default loop) but a coroutine was run by another loop, the coroutine
-was never awaited. As a result, the task would hang.
-
-Keep in mind that every internal ``await`` expression either passed
-instantly or paused, waiting for a future.
-
-It's extremely important that all tasks (coroutine runners) and
-futures use the same event loop.

+  `#4089 <https://github.com/aio-libs/aiohttp/issues/4089>`_
+- Preserve view handler function attributes across middlewares
+  `#4174 <https://github.com/aio-libs/aiohttp/issues/4174>`_
+- Fix the string representation of `ServerDisconnectedError`.
+  `#4175 <https://github.com/aio-libs/aiohttp/issues/4175>`_

+- Remove warning messages from noop.
+  `#4282 <https://github.com/aio-libs/aiohttp/issues/4282>`_
+- Raise ClientPayloadError if FormData re-processed.
+  `#4345 <https://github.com/aio-libs/aiohttp/issues/4345>`_
+- Fix a warning about unfinished task in `web_protocol.py`
+  `#4408 <https://github.com/aio-libs/aiohttp/issues/4408>`_
+- Fixed 'deflate' compressions. According to RFC 2616 now.
+  `#4506 <https://github.com/aio-libs/aiohttp/issues/4506>`_
+- Fixed OverflowError on platforms with 32-bit time_t
+  `#4515 <https://github.com/aio-libs/aiohttp/issues/4515>`_
+- Fixed request.body_exists returns wrong value for methods without body.
+  `#4528 <https://github.com/aio-libs/aiohttp/issues/4528>`_
+- Fix connecting to link-local IPv6 addresses.
+  `#4554 <https://github.com/aio-libs/aiohttp/issues/4554>`_
+- Fix a problem with connection waiters that are never awaited.
+  `#4562 <https://github.com/aio-libs/aiohttp/issues/4562>`_
+- Always make sure transport is not closing before reuse a connection.
+
+  Reuse a protocol based on keepalive in headers is unreliable.
+  For example, uWSGI will not support keepalive even it serves a
+  HTTP 1.1 request, except explicitly configure uWSGI with a
+  `--http-keepalive` option.
+
+  Servers designed like uWSGI could cause aiohttp intermittently
+  raise a ConnectionResetException when the protocol poll runs
+  out and some protocol is reused.
+  `#4587 <https://github.com/aio-libs/aiohttp/issues/4587>`_
+- Handle the last CRLF correctly even if it is received via separate TCP segment.
+  `#4630 <https://github.com/aio-libs/aiohttp/issues/4630>`_
+- Fix the register_resource function to validate route name before splitting it so that route name can include python keywords.
+  `#4691 <https://github.com/aio-libs/aiohttp/issues/4691>`_
+- Improve typing annotations for ``web.Request``, ``aiohttp.ClientResponse`` and
+  ``multipart`` module.
+  `#4736 <https://github.com/aio-libs/aiohttp/issues/4736>`_
+- Fix resolver task is not awaited when connector is cancelled
+  `#4795 <https://github.com/aio-libs/aiohttp/issues/4795>`_
+- Fix a bug "Aiohttp doesn't return any error on invalid request methods"
+  `#4798 <https://github.com/aio-libs/aiohttp/issues/4798>`_
+- Fix HEAD requests for static content.

+- Fix incorrect size calculation for memoryview
+  `#4890 <https://github.com/aio-libs/aiohttp/issues/4890>`_
+- Add HTTPMove to _all__.
+  `#4897 <https://github.com/aio-libs/aiohttp/issues/4897>`_
+- Fixed the type annotations in the ``tracing`` module.
+  `#4912 <https://github.com/aio-libs/aiohttp/issues/4912>`_
+- Fix typing for multipart ``__aiter__``.
+  `#4931 <https://github.com/aio-libs/aiohttp/issues/4931>`_
+- Fix for race condition on connections in BaseConnector that leads to exceeding the connection limit.
+  `#4936 <https://github.com/aio-libs/aiohttp/issues/4936>`_
+- Add forced UTF-8 encoding for `application/rdap+json` responses.

Subject: [PATCH 287/603] [3.7] Import `Protocol` from typing_extensions
 (#5111) (#5113)

Conditional imports must reference `sys.version_info` directly
for type checkers to be able to narrow them.  If a type checker
cannot tell whether `PY_38` is true, it will combine the imports
from both clauses in a `Union`.
However, `typing.Protocol` and `typing_extensions.Protocol` are
incompatible with each other - they do not inherit from the same class.
This produces a type error which is reported to users of aiohttp
depending on their type checking configuration..
(cherry picked from commit fb8037ab89587377c402d134dcf1a3e4a89b4918)

Subject: [PATCH 291/603] Annotate all attrs members (#5115)

* Annotate all attrs members

In py.typed packages, public attributes must be explicitly typed.
This is not an issue for mypy because the attrs mypy plug-in is able
to infer the types of attrs dynamically.  However, in other
static type checkers, like Pyright and pytype, the type of
unannotated attrs is not known statically.

Since aiohttp no longer supports Python versions older than 3.6
I've taken the liberty of converting the annotations to the native
format.

+AioHTTPTestCase is more async friendly now.
+
+For people who use unittest and are used to use unittest.TestCase
+it will be easier to write new test cases like the sync version of the TestCase class,
+without using the decorator `@unittest_run_loop`, just `async def test_*`.
+The only difference is that for the people using python3.7 and below a new dependency is needed, it is `asynctestcase`.

-      (an example is provided in the Appendix below).
-
-      "Derivative Works" shall mean any work, whether in Source or Object
-      form, that is based on (or derived from) the Work and for which the
-      editorial revisions, annotations, elaborations, or other modifications
-      represent, as a whole, an original work of authorship. For the purposes
-      of this License, Derivative Works shall not include works that remain

-      the Work and Derivative Works thereof.
-
-      "Contribution" shall mean any work of authorship, including
-      the original version of the Work and any modifications or additions
-      to that Work or Derivative Works thereof, that is intentionally
-      submitted to Licensor for inclusion in the Work by the copyright owner
-      or by an individual or Legal Entity authorized to submit on behalf of

-   2. Grant of Copyright License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      copyright license to reproduce, prepare Derivative Works of,
-      publicly display, publicly perform, sublicense, and distribute the
-      Work and such Derivative Works in Source or Object form.
-
-   3. Grant of Patent License. Subject to the terms and conditions of
-      this License, each Contributor hereby grants to You a perpetual,
-      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-      (except as stated in this section) patent license to make, have made,
-      use, offer to sell, sell, import, and otherwise transfer the Work,
-      where such license applies only to those patent claims licensable
-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You
-      institute patent litigation against any entity (including a
-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
-
-   END OF TERMS AND CONDITIONS
-
-   APPENDIX: How to apply the Apache License to your work.

<p><em>Sourced from <a href="https://github.com/pytest-dev/pytest-mock/blob/master/CHANGELOG.rst">pytest-mock's changelog</a>.</em></p>
<blockquote>
<h2>3.5.0 (2021-01-04)</h2>
<ul>
<li>
<p>Now all patch functions will emit a warning instead of raising a <code>ValueError</code> when used
as a context-manager. Thanks <code>@iforapsy</code>_ for the PR (<code>[#221](https://github.com/pytest-dev/pytest-mock/issues/221)</code>_).</p>
</li>
<li>
<p>Additionally, <code>mocker.patch.context_manager</code> is available when the user intends to mock
a context manager (for example  <code>threading.Lock</code> object), which will not emit that
warning.</p>
</li>

Subject: [PATCH 442/603] [3.8] Eliminate side-effects from the
 `ClientResponse.ok` property (#5407)

This change makes it so accessing `ClientResponse.ok` only does the status
code check.

Prior to this commit, it'd call `ClientResponse.raise_for_status()` which
in turn, closed the underlying TCP session whenever the status was 400 or
higher making it effectively impossible to keep working with the response,
including reading the HTTP response payload.

PR #5404 by @adamko147

Fixes #5403

+Fix interpretation difference of the pure-Python and the Cython-based
+HTTP parsers construct a ``yarl.URL`` object for HTTP request-target.
+
+Before this fix, the Python parser would turn the URI's absolute-path
+for ``//some-path`` into ``/`` while the Cython code preserved it as
+``//some-path``. Now, both do the latter.

Subject: [PATCH 485/603] Implement ETag support (#4594) (#5562)

This change adds an `etag` property to the response object and
`if_match`, `if_none_match` properties to the request object.
Also, it implements ETag support in static routes and fixes a
few bugs found along the way.

Subject: [PATCH 588/603] [PR #6002/d66e07c6 backport][3.8] Add xfailing
 integration tests against ``proxy.py`` (#6033)

This patch adds full end-to-end tests for sending requests to HTTP and
HTTPS endpoints through an HTTPS proxy. The first case is currently
supported and the second one is not. This is why the latter test is
marked as expected to fail. The support for TLS-in-TLS in the upstream
stdlib asyncio is currently disabled but is available in Python 3.9
via monkey-patching which is demonstrated in the added tests.

+
+Adding change notes with your PRs
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+It is very important to maintain a log for news of how
+updating to the new version of the software will affect
+end-users. This is why we enforce collection of the change
+fragment files in pull requests as per `Towncrier philosophy`_.
+
+The idea is that when somebody makes a change, they must record
+the bits that would affect end-users only including information
+that would be useful to them. Then, when the maintainers publish
+a new release, they'll automatically use these records to compose
+a change log for the respective version. It is important to
+understand that including unnecessary low-level implementation
+related details generates noise that is not particularly useful
+to the end-users most of the time. And so such details should be
+recorded in the Git history rather than a changelog.
+
+Alright! So how to add a news fragment?
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+``aiohttp`` uses `towncrier <https://pypi.org/project/towncrier/>`_
+for changelog management.
+To submit a change note about your PR, add a text file into the
+``CHANGES/`` folder. It should contain an
+explanation of what applying this PR will change in the way
+end-users interact with the project. One sentence is usually
+enough but feel free to add as many details as you feel necessary
+for the users to understand what it means.
+
+**Use the past tense** for the text in your fragment because,
+combined with others, it will be a part of the "news digest"
+telling the readers **what changed** in a specific version of
+the library *since the previous version*. You should also use
+reStructuredText syntax for highlighting code (inline or block),
+linking parts of the docs or external sites.
+If you wish to sign your change, feel free to add ``-- by
+:user:`github-username``` at the end (replace ``github-username``
+with your own!).
+
+Finally, name your file following the convention that Towncrier
+understands: it should start with the number of an issue or a
+PR followed by a dot, then add a patch type, like ``feature``,
+``doc``, ``misc`` etc., and add ``.rst`` as a suffix. If you
+need to add more than one fragment, you may add an optional
+sequence number (delimited with another period) between the type
+and the suffix.
+
+In general the name will follow ``<pr_number>.<category>.rst`` pattern,
+where the categories are:
+
+- ``feature``: Any new feature
+- ``bugfix``: A bug fix
+- ``doc``: A change to the documentation
+- ``misc``: Changes internal to the repo like CI, test and build changes
+- ``removal``: For deprecations and removals of an existing feature or behavior
+
+A pull request may have more than one of these components, for example
+a code change may introduce a new feature that deprecates an old
+feature, in which case two fragments should be added. It is not
+necessary to make a separate documentation fragment for documentation
+changes accompanying the relevant code changes.
+
+Examples for adding changelog entries to your Pull Requests

Subject: [PATCH 598/603] [PR #5914/5fab03a5 backport][3.8] Further optimize
 the logo/icon (#6059)

* Further optimized, now using viewbox of 0 0 24 24

It's not exactly required, but projects such as simple-icons use a 24 24 viewbox, and dont move the viewbox into the middle for no reason (instead starting at 0 0)

* Added color to the icon

* Update aiohttp-plain.svg

* Added same height width as original

* Update aiohttp-plain.svg

* Create 5914.misc

* Make the change note clearer
