i have a really big problem with channels. when I try to run asgi server in production the problems come up but there is no problem when running in terminal.
first let me show you a little code
class LogConsumer(AsyncConsumer):
async def websocket_connect(self, event):
print('befor')
await self.send({
"type": "websocket.accept",
"text": "hellow"
})
print('after')
async def websocket_disconnect(self, event):
print(event)
there are more but i commented them too see problem is solving or not and guess what ...
application = ProtocolTypeRouter({
'websocket': AllowedHostsOriginValidator(
AuthMiddlewareStack(
URLRouter(
[
url(r"^ws/monitoring/$", LogConsumer),
]
)
),
)
})
ASGI_APPLICATION = "fradmin_mainserver.routing.application"
CHANNEL_LAYERS = {
"default": {
"BACKEND": "channels_redis.core.RedisChannelLayer",
"CONFIG": {
"hosts": [("localhost", 6379)],
},
},
}
ASGI_THREADS = 1000
supervisor config
[fcgi-program:asgi]
socket=tcp://localhost:8008
environment=PYTHONPATH=/home/datis/.pyenv/versions/cv/bin/python
User=datis
environment=HOME="/home/datis",USER="datis"
# Directory where your site's project files are located
directory=/home/datis/PycharmProjects/fradmin_mainserver/
# Each process needs to have a separate socket file, so we use process_num
# Make sure to update "django_chanels.asgi" to match your project name
command=/home/datis/.pyenv/versions/cv/bin/daphne -u /run/uwsgi/daphne%(process_num)d.sock --fd 0 --access-log - --proxy-headers fradmin_mainserver.asgi:application
# Number of processes to startup, roughly the number of CPUs you have
numprocs=1
# Give each process a unique name so they can be told apart
process_name=asgi%(process_num)d
# Automatically start and recover processes
autostart=true
autorestart=true
# Choose where you want your log to go
stdout_logfile=/var/log/uwsgi/asgi.log
redirect_stderr=true
ok these are configurations .
when i use
daphne fradmin_mainserver.asgi:application --bind 0.0.0.0 --port 8008 --verbosity 1
there is no problem but when use this inside supervisor the only thing i get is :
2021-04-13 11:45:27,015 WARNING Application instance <Task pending coro=<SessionMiddlewareInstance.__call__() running at /home/datis/.pyenv/versions/3.6.8/envs/cv/lib/python3.6/site-packages/channels/sessions.py:183> wait_for=<Future pending cb=[<TaskWakeupMethWrapper object at 0x7f02e2222d38>()]>> for connection <WebSocketProtocol client=['127.0.0.1', 46234] path=b'/ws/monitoring/'> took too long to shut down and was killed.
even i tryed to start a service with currect code and i made :

but the result was the same:
its like websocket_connec() is never called
I tried to create it with syncconsumer but problem whas the same
but when i stop supervisorctl all runs together
