Re: Channels: channel_layer appears to time out

2018-03-09 Thread toby @ tobyz 
Update: there was an issue, and running the stock Ubuntu 16.04 Python was the 
cause; 3.5.2. 

I’ve provisioned 3.6.4, and channels is doing exactly what I ask of it.

Andrew,

Thanks for taking the time to reply. 

In classic fashion, the issue has gone away and I'm not entirely sure why. 
I suspect there might have been a page with older code buried somewhere, 
trying to do websocket things wrongly, and that was throwing things off. 
I'm sure it will rear it's head again, and if it does I will try and get a 
reproducible test case.

Hi Toby,

Do you have the latest versions of daphne, channels, asgiref and
channels_redis? This sounds supiciously like a bug I fixed a couple weeks
ago.
