The problem is that i don't know how much bytes i will receive from socket, so i just trying to loop.
buffer = ''
while True:
data, addr = sock.recvfrom(1024)
buffer += data
print buffer
As I understood recvfrom return only specified size of bytes and the discards other data, is it possible somehow continuously read this data to buffer variable?
It wont discard the data, it will just return the data in the next iteration. What you are doing in your code is perfectly correct.
The only thing I would change is a clause to break the loop:
buffer = ''
while True:
data, addr = sock.recv(1024)
if data:
buffer += data
print buffer
else:
break
An empty string signifies the connection has been broken according to the documentation
If this code still does not work then it would be good to show us how you are setting up your socket.
recv rather than recvfromExceptions and setblockingI suggest using readline as the buffer and use "\n" as the separator between lines:
#read one line from the socket
def buffered_readLine(socket):
line = ""
while True:
part = socket.recv(1)
if part != "\n":
line+=part
elif part == "\n":
break
return line
This is helpful when you want to buffer without closing the socket.
sock.recv(1024) will hang when there is no data being sent unless you close the socket on the other end.
