sockets - Python TCP Relay/Proxy Server locking up -


i have simple python proxy server i've setup. purpose take tcp stream (video) , forward tcp stream several clients (currently testing 1 start). works great until try forward (o.send(data)) data , receive/send couple packets, freeze , minute or 2 later receive/send few more packets , freeze again.

if take incoming data , load variable doesn't slow down @ all. , if both load incoming data data variable send random block of data client instead of received data doesn't freeze. feel maybe there race condition or .recv() shouldn't block don't know deadlock coming from. data flled recv, should able send right? , rinse/repeat indefinitely. can check cpu utilization top -bn1 , python script doesn't appear using cpu @ all.

the deadlock happens between .recv() , .send().

if put in debug print it'll print "data received!" ..... pause ... "data sent!" "data received!"....

import socket # listen gstreamer tcp stream.  s = socket.socket(socket.af_inet, socket.sock_stream) s.bind(("192.168.1.1", 911)) s.listen(5)  # connect video player o = socket.socket(socket.af_inet, socket.sock_stream) o.connect(("192.168.2.2",910))  clientsocket, address = s.accept()  while 1: # receive video data.       data = clientsocket.recv(4096) # forward video player      o.send(data)      print 'o'

thanks!

one of nics faulty. swapped nic , worked fine. not sure why presented in 1 way @ least found solution.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
