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.
From the description alone I can't infer any problem. Certainly
uploading
files with ftplib worked fine last time I tried. Try to remove all
unnecesary lines from your script, making it as small as possible but
still showing your problem, and post it here.
Gabriel,
Thank you for your suggestion. 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.
