(I try to run web.py with Jython 2.5rc2 but have 2 problems (the other with transformer put as another issue). I use the basic example on http://webpy.org/ (folder web with the source is in on the path). During server startup I get the following output: http://0.0.0.0:8080/ Traceback (most recent call last): File "1.py", line 22, in <module> app.run() File "I:\dev-a-workspace\dev\jywebpy\web\application.py", line 289, in run return wsgi.runwsgi(self.wsgifunc(*middleware)) File "I:\dev-a-workspace\dev\jywebpy\web\wsgi.py", line 54, in runwsgi return httpserver.runsimple(func, validip(listget(sys.argv, 1, ''))) File "I:\dev-a-workspace\dev\jywebpy\web\httpserver.py", line 223, in runsimpl e server.start() File "I:\dev-a-workspace\dev\jywebpy\web\httpserver.py", line 223, in runsimpl e server.start() File "I:\dev-a-workspace\dev\jywebpy\web\wsgiserver\__init__.py", line 1589, i n start self.socket.listen(self.request_queue_size) File "<string>", line 1, in listen File "I:\dev-a-workspace\dev\jywebpy\socket.py", line 788, in listen self._config() File "I:\dev-a-workspace\dev\jywebpy\socket.py", line 788, in listen self._config() File "I:\dev-a-workspace\dev\jywebpy\socket.py", line 727, in _config self.sock_impl.setsockopt(level, optname, self.pending_options[ (level, optn ame) ]) File "I:\dev-a-workspace\dev\jywebpy\socket.py", line 248, in setsockopt raise error(errno.ENOPROTOOPT, "Level %d option not supported on socket(%s): %d" % (level, str(self.jsocket), option)) socket.error: (43, 'Level 6 option not supported on socket(ServerSocket[addr=/0. 0.0.0,localport=8080]): 256') I have no real idea what is going on in socket module but after adding "if level == 6: continue" in line 721 (so simple removing this level) at least the web.py server does seem to start properly. Please excuse my naivity, hope this is not complete bullshit... |

Are you using a version of socket.py that you have modified yourself? I notice from your traceback that you have a local copy of socket.py in webpy/web/socket.py? The self._config() call in the _listen() method is on line 783 in the version of socket.py released with RC2, whereas your traceback gives it as being on line 788? If you have modified your local copy of socket.py, it will not be possible for me to determine why this is happening. Although I guess that you have added some socket options to your local copy of socket.py? (I must improve that error message). If you have a local copy of socket.py, please attach it to this bug report so that I can get a look at it. |

I have used the socket.py from Jython 2.5rc2's Lib/site-packages directory and copied it to my local path as I did not wanted to change to lib. I only added the additional line "if level == 6: continue" to test if I could get any further with my attempt to run web.py. Hope that helps... |

This error is happening because webpy is trying to set the socket option TCP_NODELAY on a server socket, which is not supported on java, and thus jython. I have checked in a change to error reporting for this situation, so that the error message gives the names of the option constants involved in the error, rather than the symbolic constants, which were obviously confusing. The change was made at revision 6354. You can download the updated version from http://fisheye3.atlassian.com/browse/jython/trunk/jython/Lib/socket.py Looking at the webpy code, I see that the option is set on line 1610 of file "web/wsgiserver/__init__.py" of the current release. This is only done if the "nodelay" option is set true. So if you set that option to False, then the TCP_NODELAY option is not set, thus preventing this problem. You may want to report this as a bug to the webpy folks, since unsupported socket options on jython give an exception. |
