[PD] non-socket (88)

[Lucas Cordiviola]

Hi,

I've been testing [netsend -u] for a couple of hours on Pd 0.49-0 on windows. I had no trouble if there is no receivers. I used a windows tablet and a linux box for listening. I have switch them off for a while and then re-enter to the LAN. Didn't get any "Socket operation on non-socket (88)".

A couple of things you could check:

+ Are you using Pd 0.49-0 on your raspberry?

+ Could it be that there is something on the OS that is closing "Socket connections" (or network adapter) to save battery power or something like that?

i am sending OSC messages with [netsend -u -b]

there is obviously an issue with [netsend] closing the socket if nobody is listening.
which it should not do in UDP mode.
https://github.com/pure-data/pure-data/issues/373

but this:

netsend: Socket operation on non-socket (88)

is lethal to my patch. immediate freeze
unfortunatly it occurs quite often.

i also know next to nothing about Sockets
is it a pd problem or does it stem from the os (unix jessie in my case, on raspberry) ???

also due to Christof Ressi:
I can confirm that both [iemnet/udpsend] [mrpeach/udpsend] (from Pd extended) close the socket on Linux but only [mrpeach/udpsend] gives a warning and sends a 0. I'll do a bug report.

in the meantime, are there any options to send osc via udp regardless of the existance of a receiver?

cheers!
michael

Did you tried sending every second an empty message [send ( instead of
"reopening a connection" ?

i finally could caught pd in the act of freezing:

the console said:

recv: Connection refused (111)
netsend: Socket operation on non-socket (88)
warning: 33 removed from poll list but not found


i connect every second to mobile phones that run Lemur to send and receive OSC
usually if a phone leaves the network, nothing bad happens, the console says:


recv: Connection refused (111)
netsend: Bad file descriptor (9)
warning: 32 removed from poll list but not found


So it seems to me that this non-socket(88) problem manages to freeze pd
(or is it this number: 88, which has a bad connotation in austria ?)


Thanks!
michael
