[PD-dev] SIGPIPE on iemnet's tcpserver

[Antoine Villeret]

Hi roman,

the code around networking object are some workarounds for differents bugs,
the first was a crash when client number reach 32, but it seems to be
fixed, I can't reproduce this anymore
the second was something strange if several clients connect to the same
server at the same time (when patch launch for example), so I add a
timeout, if no answer in this timeout, the client disconnect
there is also a mechanism to choose an available port at startup in server
and the client try different port until it get a connection...

all of this is quite complex for a not so difficult task : I want to make
several instance of Pd talking to each other on one machine

I started with udpsend/udpreceive but I found no way to do broadcast on
localhost and I do need to have lots of clients
multicasting is not a solution because it need to have a working networking
interface
then I tried udpserver which doesn't work (at least the version in the pd's
SVN)
then I switch to tcpserver and I got a lots of troubles...

I will try out iohannes version of iemnet and I'll also investigate those
bugs

but other (simpler) solutions are welcome :-)

best

a
