Hello John -
Forgive my doubts, as you mention I had best read the manual.
You are correct, I was using python's bind incorrectly, the correct code
fragment is shown below:
[alphonse:~] cherf% cd
Projects/Source/MacOSForge/CalendarServer/tags/release/CalendarServer-2.5/
/Users/cherf/Projects/Source/MacOSForge/CalendarServer/tags/release/CalendarServer-2.5
[alphonse:tags/release/CalendarServer-2.5] cherf% python
Python 2.6.6 (r266:84292, Jun 8 2011, 18:50:17)
[GCC 4.2.1 (Apple Inc. build 5646)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import socket
>>> skt = socket.socket (socket.AF_UNIX, socket.SOCK_STREAM)
>>> skt.bind ("/tmp/some.socket")
>>> skt.listen(5)
>>>
In fact, this works just fine on both my development machine and the server I'm
trying to install the iCal server on, the difficulty was in the use of a
relative pathname rather than an absolute name. Using a relative path on macOS
apparently does not work, however changing the fragment to an absolute name
works fine.
Unfortunately this leaves me wrestling with the original problem, which is to
understand why I'm seeing the error from Twisted.
Again, thanks for the suggestion,
Scott.
