In IronPython, using socket.getfqdn('127.0.0.1') returns the local host name.
Under CPython, this always returns 'localhost'.
The CPython documentation for getfqdn() does explicitly state "If name is
omitted or empty, it is interpreted as the local host."
Therefore, if you change your call to leave out the '0.0.0.0', then the code
will behave the same on both CPython and IronPython.
IronPython:
>>> import socket
>>> socket.getfqdn()
mydomain.name.here
CPython:
>>> import socket
>>> socket.getfqdn()
mydomain.name.here

Subject: [IronPython] socket.getfqdn problem on 2.6.1 RC1.
Hi, I´m trying to use the HTTPServer class from de BaseHTTPServer.py
on standard library on IronPython 2.6.1 RC1.
But the server stops with an socket exception on startup as shown bellow.
C:\Program Files\Tools>ipy
IronPython 2.6.1 (2.6.10920.0) on .NET 2.0.50727.3607
Type "help", "copyright", "credits" or "license" for more information.
>>> import BaseHTTPServer
>>> BaseHTTPServer.test()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Program Files\IronPython\Lib\BaseHTTPServer.py", line 584, in test
File "C:\Program Files\IronPython\Lib\SocketServer.py", line 400, in __init__
File "C:\Program Files\IronPython\Lib\BaseHTTPServer.py", line 110, in server_
bind
ValueError: IPv4 address 0.0.0.0 and IPv6 address ::0 are unspecified addresses
that cannot be used as a target address.
Parameter name: hostNameOrAddress
This is because the method getfqdn of the socket class is blowing up
when the string '0.0.0.0' is passed to it. For example:
C:\Program Files\Tools>ipy
IronPython 2.6.1 (2.6.10920.0) on .NET 2.0.50727.3607
Type "help", "copyright", "credits" or "license" for more information.
>>> import socket
>>> socket.getfqdn('0.0.0.0')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: IPv4 address 0.0.0.0 and IPv6 address ::0 are unspecified addresses
that cannot be used as a target address.
Parameter name: hostNameOrAddress
On CPython the same call returns the current host name, like bellow.
C:\Users\beppler>python
Python 2.5.4 (r254:67916, Dec 23 2008, 15:10:54) [MSC v.1310 32 bit
(Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import socket
>>> socket.getfqdn('0.0.0.0')
'Beppler.mps.interno'
>>>
Is it possible to fix this for the 2.6.1 release?
