[Moin-user] run MoinMoin with Python server?

[Kevin Altis]

Steve Holden and I found a fix for the POST handling on Windows this
weekend. Guido has assigned the tracker item to Steve, so hopefully
something will get checked in soon.

http://sourceforge.net/tracker/?func=detail&aid=427345&group_id=5470&atid=10
5470

The fix turned out to be pretty simple.

            if self.command.lower() == "post" and nbytes > 0:
                data = self.rfile.read(nbytes)
                fi.write(data)
                # now throw away data past Content-length
                while select.select([self.rfile._sock], [], [], 0)[0] != []:
                    waste = self.rfile._sock.recv(1)
            fi.close()

Only the two lines below the comment are required along with an "import
select" at the top of CGIHTTPServer.py. This is slightly verbose, so Steve
may do something a bit tighter; the code block below is around line 247,
just look for the:
  if self.command.lower() == "post" and nbytes > 0:

Please refer to the bug tracker item for more info. Anyway, MoinMoin runs
like a champ as a simple CGI with the built-in Python web server and CGI
handler.

Note that this fix was for servers running on Windows, it is still unclear
whether Python code on Unix suffers from this same POST bug of not reading
the extra CR/LF sent by IE.
