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.
resp is a string, but not the response that PASV expected; apparently
the server is sending some unexpected responses. r52739 seems to fix
that. Perhaps you should upgrade to a newer Python version.
http://svn.python.org/view?view=revrevision=52739
I know I should upgrade.That I shall do next. Not today, though. First I
need a new computer, because my OS (Windows ME) is so outdated that
installations fail with the recommendation to upgrade to a newer
installer. Anyway, I do thank you very much for your assistance. With
the r52739 fix I should be okay.

In the meantime I uploaded my entire webseite hacker style, listing the server directories after each freeze-restart and shortening the list of files to transfer by the ones that passed before the last freeze. The exercise revealed that the freezes are less predictable than it seemed in the beginning. On one occasion it occurred after the transfer of a single file from the IDLE command line (my_ftp_object.storlines (STOR file_name, f). The file did upload. So the freezes seem to occur after a successful transfer. The command-line freeze is evidence of an ftp protocol implementation or timing problem between the ftplib module and the hosting server. My code that passes files to the FTP object for transmission one by one is off the hook, so I won't bother you with it. Of course, I am in contact with the hosting service, but expect them not to assume the burden of proof. If you (or someone else) would suggest a means to visualize the transfer, dumping a stack or writing a log or something of that sort, I think I'd be on the right track.

ftpilb.FTP.stor...() freeze mystery
Hi, I am trying to upload a bunch of web pages to a hosting service. I have a connected ftplib.FTP object and can upload files manually from an IDLE command line using the methods storlines () for html files and storbinary () for the pictures. So far no problem. In order to upload the whole set of files I wrote a loop that iterates through the file names and calls either of the stor... () methods as appropriate. The loop successfully uploads eight of some twenty files and then freezes. Ctrl-C doesn't unlock the freeze. I have to kill the IDLE window which raises a confirmation request are you sure? The program is still running. Having no alternative I am sure. I open a new IDLE window and start over. Every retry fails the exact same way. My upload method with the loop has a preview mode. It goes through all the motions including opening and closing my source files but skips the stor... () methods and in addition displays all commands. The preview mode completes the iteration sequence and shows nothing unexpected. What could be the problem? I am totally fazed and will be most grateful for expert suggestions.
