Summary: ftplib.py string index out of range
Initial Comment:
The following code works great on all of the 2.3.x
releases I have used.
def
ftpFetch(localPath,remoteFileDate,ftpSite,ftpPass,ftpDir,ftpUser):
print "Fetching split_mgr report"
fileList=[]
processList=[]
ftp = FTP(ftpSite)
ftp.login(ftpUser,ftpPass)
ftp.dir('LIST '+ftpDir,fileList.append)
for x in range(len(fileList)):
if (string.find(fileList[x],remoteFileDate) != -1):
print fileList[x]
TMP=fileList[x]
output=localPath+str(TMP[45:])
print output
processList.append(output)
print processList
outfile = open(output,'w')
ftp.retrbinary('RETR '+ftpDir+TMP[45:],
open(output, 'wb').write)
ftp.quit()
print processList
return processList
However I get the following error under 2.4

discusses a similar problem under Linux in the YUM
script, I have reproduced this error under 2000, and XP.
I'm a fairly new programmer, and thus very new to
python so I hope this is enough information. I will
try and keep track of this and help out with more
information in any capacity I can.
Thank you for all your hard work and dedication.

Thank you for leaving this open. I will try and get your
example today. I'm too uneducated to realize what I'm doing
wrong, so maybe you can use my ignorance for the common good
=).

I fixed the IndexError. It should have been a protocol
error. See Lib/ftplib.py 1.74.
Leaving the bug open so the OP can make a more detailed post
so we can see what the root issue is about.

It turns out that the code in plain text bug report is more
or less readable, so I can see what you were trying to do...
Seems like you are doing
ftp.dir("LIST "+ftpDir)
But ftplib docs:
http://www.python.org/doc/current/lib/ftp-objects.html
say that you need to specify the directory
ftp.dir(ftpDir)
so it seems that you are using ftp.dir() incorrectly....
But, even then IndexError seems like a wrong kind of
exception for this kind of error...
So, I guess, my original request for a working code snippet
which would allow to reproduce the bug still stands..

Could you submit a minimalistic piece of code which
illustrates the problem?
As well as any input data which are required to reproduce it?
(SourceForge garbled your original example)
