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).
Dependencies
------------
``asgiref`` requires Python 3.6 or higher.
Contributing
------------
Please refer to the
`main Channels contributing docs <https://github.com/django/channels/blob/master/CONTRIBUTING.rst>`_.
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.
Crucially, 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.
If an application instance is found with the same `scope_id`, you are
given its input queue, otherwise one is made for you with the scope provided
and you are given that fresh new input queue. Either way, you should do
something like:
input_queue = self.get_or_create_application_instance(
"user-123456",
{"type": "testprotocol", "user_id": "123456", "username": "andrew"},
)
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.
If you override run(), make sure you handle things like launching the
application checker.

# Cython BLIS: Fast BLAS-like operations from Python and Cython, without the tears
This repository provides the [Blis linear algebra](https://github.com/flame/blis)
routines as a self-contained Python C-extension.
Currently, we only supports single-threaded execution, as this is actually best for our workloads (ML inference).

## Installation
You can install the package via pip, first making sure that `pip`, `setuptools`,
and `wheel` are up-to-date:
```bash
pip install -U pip setuptools wheel
pip install blis
```
Wheels should be available, so installation should be fast. If you want to install from source and you're on Windows, you'll need to install LLVM.
### Building BLIS for alternative architectures
The provided wheels should work on x86_64 architectures. Unfortunately we do not currently know a way to provide different wheels for alternative architectures, and we cannot provide a single binary that works everywhere. So if the wheel doesn't work for your CPU, you'll need to specify source distribution, and tell Blis your CPU architecture using the `BLIS_ARCH` environment variable.
#### a) Installing with generic arch support
```bash
BLIS_ARCH="generic" pip install spacy --no-binary blis
```
#### b) Building specific support
In order to compile Blis, `cython-blis` bundles makefile scripts for specific architectures, that are compiled by running the Blis build system and logging the commands. We do not yet have logs for every architecture, as there are some architectures we have not had access to.
[See here](https://github.com/flame/blis/blob/0.5.1/config_registry) for list of
architectures. For example, here's how to build support for the ARM architecture `cortexa57`:
```bash
git clone https://github.com/explosion/cython-blis && cd cython-blis
git pull && git submodule init && git submodule update && git submodule status
python3 -m venv env3.6
source env3.6/bin/activate
pip install -r requirements.txt
./bin/generate-make-jsonl linux cortexa57
BLIS_ARCH="cortexa57" python setup.py build_ext --inplace
BLIS_ARCH="cortexa57" python setup.py bdist_wheel
```
Fingers crossed, this will build you a wheel that supports your platform. You
could then [submit a PR](https://github.com/explosion/cython-blis/pulls) with
the `blis/_src/make/linux-cortexa57.jsonl` and
`blis/_src/include/linux-cortexa57/blis.h` files so that you can run:
```bash
BLIS_ARCH=cortexa57 pip install --no-binary=blis
```
## Usage
Two APIs are provided: a high-level Python API, and direct
[Cython](http://cython.org) access, which provides fused-type, nogil
Cython bindings to the underlying Blis linear algebra library. Fused
types are a simple template mechanism, allowing just a touch of
compile-time generic programming:
```python
cimport blis.cy
A = <float*>calloc(nN * nI, sizeof(float))
B = <float*>calloc(nO * nI, sizeof(float))
C = <float*>calloc(nr_b0 * nr_b1, sizeof(float))
blis.cy.gemm(blis.cy.NO_TRANSPOSE, blis.cy.NO_TRANSPOSE,
nO, nI, nN,
1.0, A, nI, 1, B, nO, 1,
1.0, C, nO, 1)
```
Bindings have been added as we've needed them. Please submit pull requests if
the library is missing some functions you require.
## Development
To build the source package, you should run the following command:
```bash
./bin/update-vendored-source
```
This populates the `blis/_src` folder for the various architectures, using the
`flame-blis` submodule.
## Updating the build files
In order to compile the Blis sources, we use jsonl files that provide the
explicit compiler flags. We build these jsonl files by running Blis's build
system, and then converting the log. This avoids us having to replicate the
build system within Python: we just use the jsonl to make a bunch of subprocess
calls. To support a new OS/architecture combination, we have to provide the
jsonl file and the header.
### Linux
The Linux build files need to be produced from within the manylinux1 docker
container, so that they will be compatible with the wheel building process.
First, install docker. Then do the following to start the container:
sudo docker run -it quay.io/pypa/manylinux1_x86_64:latest
Once within the container, the following commands should check out the repo and
build the jsonl files for the generic arch:
mkdir /usr/local/repos
cd /usr/local/repos
git clone https://github.com/explosion/cython-blis && cd cython-blis
git pull && git submodule init && git submodule update && git submodule
status
/opt/python/cp36-cp36m/bin/python -m venv env3.6
source env3.6/bin/activate
pip install -r requirements.txt
./bin/generate-make-jsonl linux generic --export
BLIS_ARCH=generic python setup.py build_ext --inplace
# N.B.: don't copy to /tmp, docker cp doesn't work from there.
cp blis/_src/include/linux-generic/blis.h /linux-generic-blis.h
cp blis/_src/make/linux-generic.jsonl /
Then from a new terminal, retrieve the two files we need out of the container:
sudo docker ps -l # Get the container ID
# When I'm in Vagrant, I need to go via cat -- but then I end up with dummy
# lines at the top and bottom. Sigh. If you don't have that problem and
# sudo docker cp just works, just copy the file.
sudo docker cp aa9d42588791:/linux-generic-blis.h - | cat > linux-generic-blis.h
sudo docker cp aa9d42588791:/linux-generic.jsonl - | cat > linux-generic.jsonl

ca-bundle.crt -- Bundle of CA Root Certificates
Certificate data from Mozilla as of: Thu Nov 3 19:04:19 2011#
This is a bundle of X.509 certificates of public Certificate Authorities

http://mxr.mozilla.org/mozilla/source/security/nss/lib/ckfw/builtins/certdata.txt?raw=1#
It contains the certificates in PEM format and therefore
can be directly used with curl / libcurl / php_curl, or with
an Apache+mod_ssl webserver for SSL client authentication.
