+======
+Django
+======
+
+Django is a high-level Python Web framework that encourages rapid development
+and clean, pragmatic design. Thanks for checking it out.
+
+All documentation is in the "``docs``" directory and online at
+https://docs.djangoproject.com/en/stable/. If you're just getting started,
+here's how we recommend you read the docs:
+
+* First, read ``docs/intro/install.txt`` for instructions on installing Django.
+
+* Next, work through the tutorials in order (``docs/intro/tutorial01.txt``,
+  ``docs/intro/tutorial02.txt``, etc.).
+
+* If you want to set up an actual deployment server, read
+  ``docs/howto/deployment/index.txt`` for instructions.
+
+* You'll probably want to read through the topical guides (in ``docs/topics``)
+  next; from there you can jump to the HOWTOs (in ``docs/howto``) for specific
+  problems, and check out the reference (``docs/ref``) for gory details.
+
+* See ``docs/README`` for instructions on building an HTML version of the docs.
+
+Docs are updated rigorously. If you find any problems in the docs, or think
+they should be clarified in any way, please take 30 seconds to fill out a
+ticket here: https://code.djangoproject.com/newticket
+
+To get more help:
+
+* Join the ``#django`` channel on irc.freenode.net. Lots of helpful people hang
+  out there. See https://freenode.net/kb/answer/chat if you're new to IRC.
+
+* Join the django-users mailing list, or read the archives, at
+  https://groups.google.com/group/django-users.
+
+To contribute to Django:
+
+* Check out https://docs.djangoproject.com/en/dev/internals/contributing/ for
+  information about getting involved.
+
+To run Django's test suite:
+
+* Follow the instructions in the "Unit tests" section of
+  ``docs/internals/contributing/writing-code/unit-tests.txt``, published online at
+  https://docs.djangoproject.com/en/dev/internals/contributing/writing-code/unit-tests/#running-the-unit-tests
+
+Supporting the Development of Django

+
+ASGI is a standard for Python asynchronous web apps and servers to communicate
+with each other, and positioned as an asynchronous successor to WSGI. You can
+read more at https://asgi.readthedocs.io/en/latest/
+
+This package includes ASGI base libraries, such as:
+
+* Sync-to-async and async-to-sync function wrappers, ``asgiref.sync``
+* Server base classes, ``asgiref.server``
+* A WSGI-to-ASGI adapter, in ``asgiref.wsgi``
+
+
+Function wrappers
+-----------------
+
+These allow you to wrap or decorate async or sync functions to call them from
+the other style (so you can call async functions from a synchronous thread,
+or vice-versa).
+
+In particular:
+
+* AsyncToSync lets a synchronous subthread stop and wait while the async
+  function is called on the main thread's event loop, and then control is
+  returned to the thread when the async function is finished.
+
+* SyncToAsync lets async code call a synchronous function, which is run in
+  a threadpool and control returned to the async coroutine when the synchronous
+  function completes.
+
+The idea is to make it easier to call synchronous APIs from async code and
+asynchronous APIs from synchronous code so it's easier to transition code from
+one style to the other. In the case of Channels, we wrap the (synchronous)
+Django view system with SyncToAsync to allow it to run inside the (asynchronous)
+ASGI server.
+
+Note that exactly what threads things run in is very specific, and aimed to
+keep maximum compatibility with old synchronous code. See
+"Synchronous code & Threads" below for a full explanation. By default,
+``sync_to_async`` will run all synchronous code in the program in the same
+thread for safety reasons; you can disable this for more performance with
+``@sync_to_async(thread_sensitive=False)``, but make sure that your code does
+not rely on anything bound to threads (like database connections) when you do.
+
+
+Threadlocal replacement
+-----------------------
+
+This is a drop-in replacement for ``threading.local`` that works with both
+threads and asyncio Tasks. Even better, it will proxy values through from a
+task-local context to a thread-local context when you use ``sync_to_async``
+to run things in a threadpool, and vice-versa for ``async_to_sync``.
+
+If you instead want true thread- and task-safety, you can set
+``thread_critical`` on the Local object to ensure this instead.
+
+
+Server base classes
+-------------------
+
+Includes a ``StatelessServer`` class which provides all the hard work of
+writing a stateless server (as in, does not handle direct incoming sockets
+but instead consumes external streams or sockets to work out what is happening).
+
+An example of such a server would be a chatbot server that connects out to
+a central chat server and provides a "connection scope" per user chatting to
+it. There's only one actual connection, but the server has to separate things
+into several scopes for easier writing of the code.
+
+You can see an example of this being used in `frequensgi <https://github.com/andrewgodwin/frequensgi>`_.
+
+
+WSGI-to-ASGI adapter
+--------------------
+
+Allows you to wrap a WSGI application so it appears as a valid ASGI application.
+
+Simply wrap it around your WSGI application like so::
+
+    asgi_application = WsgiToAsgi(wsgi_application)
+
+The WSGI application will be run in a synchronous threadpool, and the wrapped
+ASGI application will be one that accepts ``http`` class messages.
+
+Please note that not all extended features of WSGI may be supported (such as
+file handles for incoming POST bodies).
+
+

+Testing
+'''''''
+
+To run tests, make sure you have installed the ``tests`` extra with the package::
+
+    cd asgiref/
+    pip install -e .[tests]
+    pytest
+
+
+Building the documentation
+''''''''''''''''''''''''''
+
+The documentation uses `Sphinx <http://www.sphinx-doc.org>`_::
+
+    cd asgiref/docs/
+    pip install sphinx
+
+To build the docs, you can use the default tools::
+
+    sphinx-build -b html . _build/html  # or `make html`, if you've got make set up
+    cd _build/html
+    python -m http.server
+
+...or you can use ``sphinx-autobuild`` to run a server and rebuild/reload
+your documentation changes automatically::
+
+    pip install sphinx-autobuild
+    sphinx-autobuild . _build/html
+
+
+Releasing
+'''''''''
+
+To release, first add details to CHANGELOG.txt and update the version number in ``asgiref/__init__.py``.
+
+Then, build and push the packages::
+
+    python -m build
+    twine upload dist/*
+    rm -r build/ dist/

+Implementation Details
+----------------------
+
+Synchronous code & threads
+''''''''''''''''''''''''''
+
+The ``asgiref.sync`` module provides two wrappers that let you go between
+asynchronous and synchronous code at will, while taking care of the rough edges
+for you.
+
+Unfortunately, the rough edges are numerous, and the code has to work especially
+hard to keep things in the same thread as much as possible. Notably, the
+restrictions we are working with are:
+
+* All synchronous code called through ``SyncToAsync`` and marked with
+  ``thread_sensitive`` should run in the same thread as each other (and if the
+  outer layer of the program is synchronous, the main thread)
+
+* If a thread already has a running async loop, ``AsyncToSync`` can't run things
+  on that loop if it's blocked on synchronous code that is above you in the
+  call stack.
+
+The first compromise you get to might be that ``thread_sensitive`` code should
+just run in the same thread and not spawn in a sub-thread, fulfilling the first
+restriction, but that immediately runs you into the second restriction.
+
+The only real solution is to essentially have a variant of ThreadPoolExecutor
+that executes any ``thread_sensitive`` code on the outermost synchronous
+thread - either the main thread, or a single spawned subthread.
+
+This means you now have two basic states:
+
+* If the outermost layer of your program is synchronous, then all async code
+  run through ``AsyncToSync`` will run in a per-call event loop in arbitrary
+  sub-threads, while all ``thread_sensitive`` code will run in the main thread.
+
+* If the outermost layer of your program is asynchronous, then all async code
+  runs on the main thread's event loop, and all ``thread_sensitive`` synchronous
+  code will run in a single shared sub-thread.
+
+Cruicially, this means that in both cases there is a thread which is a shared
+resource that all ``thread_sensitive`` code must run on, and there is a chance
+that this thread is currently blocked on its own ``AsyncToSync`` call. Thus,
+``AsyncToSync`` needs to act as an executor for thread code while it's blocking.
+
+The ``CurrentThreadExecutor`` class provides this functionality; rather than
+simply waiting on a Future, you can call its ``run_until_future`` method and
+it will run submitted code until that Future is done. This means that code
+inside the call can then run code on your thread.

+    Base server class that handles basic concepts like application instance
+    creation/pooling, exception handling, and similar, for stateless protocols
+    (i.e. ones without actual incoming connections to the process)

+    Your code should override the handle() method, doing whatever it needs to,
+    and calling get_or_create_application_instance with a unique `scope_id`
+    and `scope` for the scope it wants to get.
+

+    )
+    input_queue.put_nowait(message)
+
+    If you try and create an application instance and there are already
+    `max_application` instances, the oldest/least recently used one will be
+    reclaimed and shut down to make space.
+
+    Application coroutines that error will be found periodically (every 100ms
+    by default) and have their exceptions printed to the console. Override
+    application_exception() if you want to do more when this happens.
