Re: copas timeout?

[gary ng <garyng2000@...>]

I don't think copas works the way you describe.

copas.receive(skt,"*l") would put the thread in 'suspended' state when the lower socket layer return 'timeout'(and the timeout is always 0) until it gets a full line or the socket is closed.

You are right that if you want to put a timeout on stalled connection, that would be in the copas interal loop.

I believe I have submitted some patch which is a watchdog function that was mainly designed for really stalled connection where the select() would never come back.
