|

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 3.8 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.
|
||||
|
||||

||||

This is a namespace object (similar to `threading.local`) where data is

also local to the current async task (if there is one).
|
||||
|
||||
In async threads, local means in the same sense as the `contextvars`

module - i.e. a value set in an async frame will be visible:
|
||||
|
||||
- to other async code `await`-ed from this frame.

- to tasks spawned using `asyncio` utilities (`create_task`, `wait_for`,

`gather` and probably others).

- to code scheduled in a sync thread using `sync_to_async`
|

In "sync" threads (a thread with no async event loop running), the

data is thread-local, but additionally shared with async code executed
|

via the `async_to_sync` utility, which schedules async code in a new thread
|

and copies context across to that thread.

If `thread_critical` is True, then the local will only be visible per-thread,

behaving exactly like `threading.local` if the thread is sync, and as

||||
`contextvars` if the thread is async. This allows genuinely thread-sensitive
|
||||
code (such as DB handles) to be kept stricly to their initial thread and
|
||||
disable the sharing across `sync_to_async` and `async_to_sync` wrapped calls.

A. HISTORY OF THE SOFTWARE
|
||||
==========================
|
||||
|
||||
Python was created in the early 1990s by Guido van Rossum at Stichting
|
||||
Mathematisch Centrum (CWI, see https://www.cwi.nl) in the Netherlands
|
||||
as a successor of a language called ABC. Guido remains Python's
|
||||
principal author, although it includes many contributions from others.
|
||||
|
||||
In 1995, Guido continued his work on Python at the Corporation for
|
||||
National Research Initiatives (CNRI, see https://www.cnri.reston.va.us)
|
||||
in Reston, Virginia where he released several versions of the
|
||||
software.
|
||||
|
||||
In May 2000, Guido and the Python core development team moved to
|
||||
BeOpen.com to form the BeOpen PythonLabs team. In October of the same
|
||||
year, the PythonLabs team moved to Digital Creations, which became
|
||||
Zope Corporation. In 2001, the Python Software Foundation (PSF, see
|
||||
https://www.python.org/psf/) was formed, a non-profit organization
|
||||
created specifically to own Python-related Intellectual Property.
|
||||
Zope Corporation was a sponsoring member of the PSF.
|
||||
|
||||
All Python releases are Open Source (see https://opensource.org for
|
||||
the Open Source Definition). Historically, most, but not all, Python
|
||||
releases have also been GPL-compatible; the table below summarizes
|
||||
the various releases.
|
||||
|
||||
Release Derived Year Owner GPL-
|
||||
from compatible? (1)
|
||||
|
||||
0.9.0 thru 1.2 1991-1995 CWI yes
|
||||
1.3 thru 1.5.2 1.2 1995-1999 CNRI yes
|
||||
1.6 1.5.2 2000 CNRI no
|
||||
2.0 1.6 2000 BeOpen.com no
|
||||
1.6.1 1.6 2001 CNRI yes (2)
|
||||
2.1 2.0+1.6.1 2001 PSF no
|
||||
2.0.1 2.0+1.6.1 2001 PSF yes
|
||||
2.1.1 2.1+2.0.1 2001 PSF yes
|
||||
2.1.2 2.1.1 2002 PSF yes
|
||||
2.1.3 2.1.2 2002 PSF yes
|
||||
2.2 and above 2.1.1 2001-now PSF yes
|
||||
|
||||
Footnotes:
|
||||
|
||||
(1) GPL-compatible doesn't mean that we're distributing Python under
|
||||
the GPL. All Python licenses, unlike the GPL, let you distribute
|
||||
a modified version without making your changes open source. The
|
||||
GPL-compatible licenses make it possible to combine Python with
|
||||
other software that is released under the GPL; the others don't.
|
||||
|
||||
(2) According to Richard Stallman, 1.6.1 is not GPL-compatible,
|
||||
because its license has a choice of law clause. According to
|
||||
CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1
|
||||
is "not incompatible" with the GPL.
|
||||
|
||||
Thanks to the many outside volunteers who have worked under Guido's
|
||||
direction to make these releases possible.

et_xmfile
|
||||
=========
|
||||
|
||||
XML can use lots of memory, and et_xmlfile is a low memory library for creating large XML files
|
||||
And, although the standard library already includes an incremental parser, `iterparse` it has no equivalent when writing XML. Once an element has been added to the tree, it is written to
|
||||
the file or stream and the memory is then cleared.
|
||||
|
||||
This module is based upon the `xmlfile module from lxml <http://lxml.de/api.html#incremental-xml-generation>`_ with the aim of allowing code to be developed that will work with both libraries.
|
||||
It was developed initially for the openpyxl project, but is now a standalone module.
|
||||
|
||||
The code was written by Elias Rabel as part of the `Python Düsseldorf <http://pyddf.de>`_ openpyxl sprint in September 2014.
|
||||
|
||||
Proper support for incremental writing was provided by Daniel Hillier in 2024
|
||||
|
||||
Note on performance
|
||||
-------------------
|
||||
|
||||
The code was not developed with performance in mind, but turned out to be faster than the existing SAX-based implementation but is generally slower than lxml's xmlfile.
|
||||
There is one area where an optimisation for lxml may negatively affect the performance of et_xmfile and that is when using the `.element()` method on the xmlfile context manager. It is, therefore, recommended simply to create Elements write these directly, as in the sample code.

Takes precedence over any default namespace

*short_empty_elements* -- controls the formatting of elements

that contain no content. If True (default)

tag, otherwise they are emitted as a pair

default_namespace argument, if supplied, takes precedence

*root_ns_only* -- bool indicating namespace declrations should only

passes of the xml tree adding additional time to

the writing process. This is primarily meant to

*minimal_ns_only* -- bool indicating only namespaces that were used

Introduction
|
||||
------------
|
||||
|
||||
openpyxl is a Python library to read/write Excel 2010 xlsx/xlsm/xltx/xltm files.
|
||||
|
||||
It was born from lack of existing library to read/write natively from Python
|
||||
the Office Open XML format.
|
||||
|
||||
All kudos to the PHPExcel team as openpyxl was initially based on PHPExcel.
|
||||
|
||||
|
||||
Security
|
||||
--------
|
||||
|
||||
By default openpyxl does not guard against quadratic blowup or billion laughs
|
||||
xml attacks. To guard against these attacks install defusedxml.
|
||||
|
||||
Mailing List
|
||||
------------
|
||||
|
||||
The user list can be found on http://groups.google.com/group/openpyxl-users
|
||||
|
||||
|
||||
Sample code::
|
||||
|
||||
from openpyxl import Workbook
|
||||
wb = Workbook()
|
||||
|
||||
# grab the active worksheet
|
||||
ws = wb.active
|
||||
|
||||
# Data can be assigned directly to cells
|
||||
ws['A1'] = 42
|
||||
|
||||
# Rows can also be appended
|
||||
ws.append([1, 2, 3])
|
||||
|
||||
# Python types will automatically be converted
|
||||
import datetime
|
||||
ws['A2'] = datetime.datetime.now()
|
||||
|
||||
# Save the file
|
||||
wb.save("sample.xlsx")
|
||||
