[Jython-users] TCP_NODELAY in Jython 2.7: protocol not available

[Julien D. <ju...@jd...>]

Hi,

It seems one can't set TCP_NODELAY on a socket in Jython 2.7, on both 
Windows and Linux. It works just fine on Jython 2.5.4rc1 on the same 
JVM. Can others replicate this? Should I report the bug somewhere else?

Jython 2.7.0 (default:9987c746f838, Apr 29 2015, 02:25:11)
[OpenJDK 64-Bit Server VM (Oracle Corporation)] on java1.7.0_79

 >>> import socket
 >>> s = socket.socket(socket.AF_INET,socket.SOCK_STREAM,0)
 >>> s.setsockopt(socket.SOL_TCP,socket.TCP_NODELAY,0)
Traceback (most recent call last):

AttributeError: 'module' object has no attribute 'SOL_TCP'

_socket.error: [Errno 92] Protocol not available


By the way, thanks to the developers for the great work of releasing 2.7.
