Application Overview
This web application is a basic Django project connected to a PostgreSQL database.
Django web service: Runs a Django development server.
PostgreSQL database service: Stores data for the Django application.
The services are configured to communicate with each other over a custom virtual network, and the database data is persisted in a named volume.
Project Structure
The repository contains the following key files:
docker-compose.yml: Defines the services (Django and PostgreSQL) and configurations.
Dockerfile: Defines the configuration for building the Django web service.
wait-for-it.sh: A script that ensures the Django app waits for PostgreSQL to be ready before starting.
requirements.txt: Python dependencies for the Django application.
manage.py: The Django projects command-line utility.
prepare-app.sh: Script to prepare the application environment (build images, create volumes, and networks).
start-app.sh: Script to start the application (launch containers and configure them to restart on failure).
stop-app.sh: Script to stop the containers (pause the application without resetting the state).
remove-app.sh: Script to remove all traces of the application (cleanup).
Virtual Networks and Named Volumes
Network: mic_default_san
Custom network for communication between the services.
Volume: postgres_data
A named volume used to persist PostgreSQL data so that data is not lost if the container is stopped or removed.
Container Configuration
PostgreSQL Service
Image: postgres:13
Environment variables:
POSTGRES_DB: Database name (mydatabase)
POSTGRES_USER: Database user (myuser)
POSTGRES_PASSWORD: Database password (mypassword)
Ports: Exposes PostgreSQL on localhost:5432
Volume: Persists data in the postgres_data volume.
Django Web Service
Build Context: The Dockerfile is used to build the web service container.
Command: Waits for PostgreSQL to be available before starting the Django development server.
Ports: Exposes the Django app on localhost:8000
Environment Variables:
DATABASE_URL: Connection string for the database.
Instructions for Running the Application
Step 1: Prepare the Application
Run the prepare-app.sh script to build the Docker images, create named volumes, and set up networks.
bash
Copy
Edit
./prepare-app.sh
Step 2: Start the Application
Run the start-app.sh script to start the application. This will launch the containers, and you can access the web application in your browser.
bash
Copy
Edit
./start-app.sh
After running the script, you will see the following message:
arduino
Copy
Edit
The app is available at http://localhost:8000
Step 3: Open the Web Application
Open a browser and navigate to http://localhost:8000 to view the Django application.
Step 4: Stop the Application
To stop the application without removing containers and volumes, use the stop-app.sh script. This will pause the services but retain the current state.
bash
Copy
Edit
./stop-app.sh
Step 5: Remove the Application
If you want to completely remove all containers, networks, and volumes created by the application, use the remove-app.sh script.
bash
Copy
Edit
./remove-app.sh
After running the script, everything related to the application will be removed.
Example Workflow
Heres an example of working with the application:
bash
Copy
Edit
# Prepare the application
./prepare-app.sh
Preparing app ...
# Run the application
./start-app.sh
Running app ...
The app is available at http://localhost:8000
# Open the web application in a browser.
# Stop the application
./stop-app.sh
Stopping app ...
# Remove the application
./remove-app.sh
Removed app.

.Synopsis
Activate a Python virtual environment for the current PowerShell session.
.Description
Pushes the python executable for a virtual environment to the front of the
$Env:PATH environment variable and sets the prompt to signify that you are
in a Python virtual environment. Makes use of the command line switches as
well as the `pyvenv.cfg` file values present in the virtual environment.
.Parameter VenvDir
Path to the directory that contains the virtual environment to activate. The
default value for this is the parent of the directory that the Activate.ps1
script is located within.
.Parameter Prompt
The prompt prefix to display when this virtual environment is activated. By
default, this prompt is the name of the virtual environment folder (VenvDir)
surrounded by parentheses and followed by a single space (ie. '(.venv) ').
.Example
Activate.ps1
Activates the Python virtual environment that contains the Activate.ps1 script.
.Example
Activate.ps1 -Verbose
Activates the Python virtual environment that contains the Activate.ps1 script,
and shows extra information about the activation as it executes.
.Example
Activate.ps1 -VenvDir C:\Users\MyUser\Common\.venv
Activates the Python virtual environment located in the specified location.
.Example
Activate.ps1 -Prompt "MyPython"
Activates the Python virtual environment that contains the Activate.ps1 script,
and prefixes the current prompt with the specified string (surrounded in
parentheses) while the virtual environment is active.
.Notes
On Windows, it may be required to enable this Activate.ps1 script by setting the
execution policy for the user. You can do this by issuing the following PowerShell
command:
PS C:\> Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
For more information on Execution Policies:

.Synopsis
Remove all shell session elements added by the Activate script, including the
addition of the virtual environment's Python executable from the beginning of
the PATH variable.
.Parameter NonDestructive
If present, do not remove this function from the global namespace for the
session.

<#
.Description
Get-PyVenvConfig parses the values from the pyvenv.cfg file located in the
given folder, and returns them in a map.
For each line in the pyvenv.cfg file, if that line can be parsed into exactly
two strings separated by `=` (with any amount of whitespace surrounding the =)
then it is considered a `key = value` line. The left hand string is the key,
the right hand is the value.
If the value starts with a `'` or a `"` then the first and last character is
stripped from the value before being captured.
.Parameter ConfigDir
Path to the directory that contains the `pyvenv.cfg` file.

Django is licensed under the three-clause BSD license; see the file
LICENSE for details.
Django includes code from the Python standard library, which is licensed under
the Python license, a permissive open source license. The copyright and license
is included below for compliance with Python's terms.
----------------------------------------------------------------------
Copyright (c) 2001-present Python Software Foundation; All Rights Reserved
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

2.1.1 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.

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.libera.chat``. Lots of helpful people
hang out there. `Webchat is available <https://web.libera.chat/#django>`_.
* Join the django-users mailing list, or read the archives, at
https://groups.google.com/group/django-users.
* Join the `Django Discord community <https://chat.djangoproject.com>`_.
* Join the community on the `Django Forum <https://forum.djangoproject.com/>`_.
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

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.
Maintenance and Security
------------------------
To report security issues, please contact security@djangoproject.com. For GPG
signatures and more security process information, see
https://docs.djangoproject.com/en/dev/internals/security/.
To report bugs or request new features, please open a new GitHub issue.
This repository is part of the Channels project. For the shepherd and maintenance team, please see the

In async threads, local means in the same sense as the `contextvars`

- 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.
Unlike plain `contextvars` objects, this utility is threadsafe.
