Thanks a million! Here's a way out by the look of it. As the devil is in
the details I get an error that indicates an inconsistency in my ftplib
library (2.4) (*** marks my comments):
Traceback (most recent call last):
File "<pyshell#65>", line 1, in -toplevel-
d2jm = upload.run (1)
File "I:/DOK/projects/WEB/JM\upload.py", line 369, in run
File "I:/DOK/projects/WEB/JM\upload.py", line 342, in copy_1_2
try: self.FS2.storbinary ('STOR %s' % name, f, timeout = timeout)
*** Here's the call to the overwritten method with the timeout.
File "I:/DOK/projects/WEB/JM\upload.py", line 440, in storbinary
self.connection = self.transfercmd (command) *** command is 'STOR
(target file name)'. Control passes to ftplib
File "C:\PYTHON24\lib\ftplib.py", line 345, in transfercmd
return self.ntransfercmd(cmd, rest)
File "C:\PYTHON24\lib\ftplib.py", line 321, in ntransfercmd
host, port = self.makepasv()
File "C:\PYTHON24\lib\ftplib.py", line 299, in makepasv
host, port = parse227(self.sendcmd('PASV'))

raise error_reply, resp
error_reply: 200 TYPE is now 8-bit binary <*** 'is now' indicates
something has changed resulting in an inconsistency
Line 566 in PYTHON24/lib/ftplib.py:
'''Parse the '227' response for a PASV request.
Raises error_proto if it does not contain '(h1,h2,h3,h4,p1,p2)'

if resp[:3] != '227':
raise error_reply, resp *** Line 566
Is 'resp' supposed to be an int (227) rather than a string ('227')?
Probably a wrong conclusion. In version 2.5 it is still a string.
Anyway, I can't start editing the library trial-and-error style. So, I
do thank you for the push. Mores pushes will be greatly appreciated, but
I hesitate to invite travel companions for a stroll into this wilderness.
