ftplib returns EOFError

[Jon Bowlas]

Hi All,

I've written a little method to connect to an ftpserver which works well,
however when I send a file using this ftp connection oddly I _sometimes_ get
returned an EOFError from ftplib.getline even though my file is actually
transferred.

Here's my script:

def uploadViaFtp(self, file, filename):
'''A method to upload a file via ftp'''
ftpserverloc = self.getItunesUftpServer()
ftpserverusername = self.getItunesUftpUser()
ftpserverpassword = self.getItunesUftpPsswd()
ftp = ftplib.FTP(ftpserverloc)
ftp.login(ftpserverusername, ftpserverpassword)
try:
ftp.storbinary("STOR " + filename, file, 1024)
finally:
file.close()
ftp.quit()
And here's the traceback:
Traceback (innermost last):
Module ZPublisher.Publish, line 114, in publish
Module ZPublisher.mapply, line 88, in mapply
Module ZPublisher.Publish, line 40, in call_object

Module ftplib, line 207, in getresp
Module ftplib, line 193, in getmultiline
Module ftplib, line 183, in getline
EOFError
Any help in catching and ignoring this error would be greatly appreciated.

Jon

ftp.quit() attempts to send a quit command and wait for the response
before closing. Apparently, sometime the connection is already closed
(don't know why) and you get the exception.

I guess you could do something like this:

try:
ftp.quit()
except EOFError:
ftp.close()
