Thanks!

I don't know if it was on purpose but you forgot to update the pypi package.

Hi there,

This is a bug that should be fixed in the latest release of Daphne that I
put out a few hours ago.

Channels websocket disconnecting after ~1min

2018-02-04 Thread Ahmed Magdy

Hello, and sorry for lots of questions about channels. 

I can connect to the websocket from JavaScript and send/receive normally 
for exactly 60~61sec after that the HTTP request is repeated on it's own 
and the websocket disconnects.
Sometimes the HTTP get request is repeated more than once before the 
websocket disconnection.

Even just connecting and waiting for 60~61secs result in the same thing.

Hi, you have a typo in your models.py in this line:

 votes = models.InterferField(default=0)

It should be IntegerField.

Using this guide:  https://docs.djangoproject.com/en/2.0/intro/tutorial02/

I get this output - way over my head. Any ideas?
(I have tried changing the settings.py INSTALLED_APPS to just 'polls' as

Here's the function that raises the exception.

def send_message(self, text_data):
   session_id = self.scope['url_route']['kwargs']['session_id']
   AsyncToSync(self.channel_layer.group_send)(
   'chat-{0}'.format(session_id),
   {
   "type": "chat.message",
   "text": text_data,
   },
   )

Re: Django-hotsauce: Current status and roadmap

2018-02-04 Thread Etienne Robillard

Hi,

Is wrk (https://github.com/wg/wrk) any better than ab for making HTTP
benchmarks of django applications?

how should i collect wrk input to make graphs in Python?

Hi,

Actually, I want to benchmark the WSGI application/handler of Django
2.0.1.

And, I want to compare the Gevent loop engine with python based
poll/epoll .

Do i really need to setup django with uwsgi to make theses
tests/benchmarks?

Hi,

Any ideas of good python library for benchmarking standalone Django
2.0 http server?

Thanks in advance,

Hi Avraham,

Le 2018-01-31 à 06:35, Avraham Serour a écrit :

Why do you call it microframework?

Because it still depends mostly on the core Django API.

You should prove it is high performance, benchmark, measure,
compare and show some cool graphs

All right. I'm planning to benchmark the following:

Django-hotsauce 0.8.2 with Cython extensions
Django-hotsauce 0.8.2 with CPython 3.7
Django-hotsauce 0.8.2 with ZODB database
Django-hotsauce 0.9.0 with PyPy 5.9
Django-hotsauce 0.9.0 with CPython 3.7
Django-hotsauce 0.9.0 with ZODB database
Django 1.11.7 with SQLite database
Django 1.11.7 with CPython 3.7
Django 1.11.7 with PyPy 5.9
Django 2.0.1 with SQLite database
Django 2.0.1 with CPython 3.7
Django 2.0.1 with PyPy 5.9

I already have a Django project, is it a drop in replacement?

Technically, it is a full-scale web microframework on top of Django.
You still need to install Django to run Django-hotsauce.

My project uses python 3.6 while you only have experimental support
for 3.5. I'm not going back, you should have already experimental
support for 3.7 at least

I don't expect huge differences between python 3.5 and 3.7. I will
try to update in order to make cool benchmarks. :)

Many thanks for your input!

Hi everyone,

This is a quick post to present the current state of
development in Django-hotsauce, a high-performance and scalable
WSGI microframework on top of Django and others.

Django-hotsauce has now reached the 0.9 milestone. New major
features now supported includes:

* uWSGI support with Gevent loop engine
* Full ZODB databases support through the Schevo DBMS
* OAuth2 authentication and authorization support with
thread-local request storage based on Werkzeug
* Experimental PyPy 5.9 and CPython 3.5 support
* Backward compatibility with Django 1.4 and Django 1.11

What should be done next? How can Django-hotsauce attract a
larger audience?

Best regards,

Etienne
