Thanks both Michael and Bert for explanation. process x thread
Yes the documentation confuse me a little bit specially this sentence in channel_timeout docs.

"Inactive" is defined as "has received no data from a client and has sent no data to a client".

Best regards Michal

Hey Michal,

Unfortunately there is nothing that will cause Waitress to kill a thread, because killing a thread in Python is not possible. The channel_timeout refers to how long a keep-alive connection stays open, a request that is processing in the WSGI thread will still be considered open, and active. The documentation around this probably needs a bit more work.

What you want is not possible with waitress.

Hello,
I can not figure out how to setup timeout (request processing takes to much time) and size limit for output data.

I am starting server like this:


|serve(application, host='0.0.0.0', port=port, cleanup_interval=2, channel_timeout=4 )
|

I am using Werkzeug |Request| and |Response| objects and |jsonrpcserver dispatch| method to delegate request to my processing method. In this method I have

|time.sleep(timeToSleep)
|

But even I setup |timeToSleep| much bigger (30s) than |channel_timeout (4s)| I can seen that the request is always processed sucefully?


For output size limit I even can not find any setting argument.


In best case, if one of these limit would be fulfill the server stop/cancel/kill according process/thread and returns to client some meaningful response.


Thanks for any help.
