A. HISTORY OF THE SOFTWARE |
||||
|
========================== |
||||
|
|
||||
|
Python was created in the early 1990s by Guido van Rossum at Stichting |
||||
|
Mathematisch Centrum (CWI, see http://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 http://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 http://www.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) |
||||
|

||||
|

||||
|

||||
|
|
||||
|
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. |

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. |
||||
|

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 3.7 or higher. |
||||
|
|
||||
|
|
||||
|
Contributing |
||||
|
------------ |
||||

|
|
||||
|
|
||||
|
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. |
||||

class FormHelper(DynamicLayoutHandler): |
||||
|
""" |
||||
|
This class controls the form rendering behavior of the form passed to |
||||
|
the `{% crispy %}` tag. For doing so you will need to set its attributes |
||||
|
and pass the corresponding helper object to the tag:: |
||||
|
|
||||
|
{% crispy form form.helper %} |
||||
|
|
||||
|
Let's see what attributes you can set and what form behaviors they apply to: |
||||
|
|
||||
|
**form_method**: Specifies form method attribute. |
||||
|
You can set it to 'POST' or 'GET'. Defaults to 'POST' |
||||
|
|
||||
|
**form_action**: Applied to the form action attribute: |
||||
|
- Can be a named url in your URLconf that can be executed via the `{% url %}` template tag. \ |
||||
|
Example: 'show_my_profile'. In your URLconf you could have something like:: |
||||
|
|
||||
|
path('show/profile/', 'show_my_profile_view', name = 'show_my_profile') |
||||
|
|
||||
|
- It can simply point to a URL '/whatever/blabla/'. |
||||
|
|
||||
|
**form_id**: Generates a form id for dom identification. |
||||
|
If no id provided then no id attribute is created on the form. |
||||
|
|
||||
|
**form_class**: String containing separated CSS classes to be applied |
||||
|
to form class attribute. The form will always have by default |
||||
|
'uniForm' class. |
||||
|
|
||||
|
**form_group_wrapper_class**: String containing separated CSS classes to be applied |
||||
|
to each row of inputs. |
||||
|
|
||||
|
**form_tag**: It specifies if <form></form> tags should be rendered when using a Layout. |
||||
|
If set to False it renders the form without the <form></form> tags. Defaults to True. |
||||
|
|
||||
|
**form_error_title**: If a form has `non_field_errors` to display, they |
||||
|
are rendered in a div. You can set title's div with this attribute. |
||||
|
Example: "Oooops!" or "Form Errors" |
||||
|
|
||||
|
**formset_error_title**: If a formset has `non_form_errors` to display, they |
||||
|
are rendered in a div. You can set title's div with this attribute. |
||||
|
|
||||
|
**form_style**: Uni-form has two built in different form styles. You can choose |
||||
|
your favorite. This can be set to "default" or "inline". Defaults to "default". |
||||
|
|
||||
|
**include_media**: Whether to automatically include form media. Set to False if |
||||
|
you want to manually include form media outside the form. Defaults to True. |
||||
|
|
||||
|
Public Methods: |
||||
|
|
||||
|
**add_input(input)**: You can add input buttons using this method. Inputs |
||||
|
added using this method will be rendered at the end of the form/formset. |
||||
|
|
||||
|
**add_layout(layout)**: You can add a `Layout` object to `FormHelper`. The Layout |
||||
|
specifies in a simple, clean and DRY way how the form fields should be rendered. |
||||
|
You can wrap fields, order them, customize pretty much anything in the form. |
||||
|
|
||||
|
Best way to add a helper to a form is adding a property named helper to the form |
||||
|
that returns customized `FormHelper` object:: |
||||
|
|
||||
|
from crispy_forms.helper import FormHelper |
||||
|
from crispy_forms.layout import Submit |
||||
|
|
||||
|

title = forms.CharField(_("Title")) |

||||
|
helper = FormHelper() |

|
helper.form_id = 'this-form-rocks' |
||||
|
helper.form_class = 'search' |
||||
|
helper.add_input(Submit('save', 'save')) |
||||
|
[...] |
||||
|
return helper |
||||
|
|
||||
|
You can use it in a template doing:: |
||||
|
|
||||
|
