Attachment with "ü" causes python error an is not attached

Description

We found a problem with python-code execution if there is an german "Umlaut" (ü) in the filename of an attachment.

email2trac produces an error in the user.log of the server { Mar 10 17:00:04 ks35958 email2trac: Traceback (most recent call last): Mar 10 17:00:04 ks35958 email2trac: File "/usr/bin/email2trac", line 1249, in ? tktparser.parse(sys.stdin) Mar 10 17:00:04 ks35958 email2trac: File "/usr/bin/email2trac", line 818, in parse self.new_ticket(m, spam_msg) Mar 10 17:00:04 ks35958 email2trac: File "/usr/bin/email2trac", line 757, in new_ticket str = self.attachments(msg, tkt) Mar 10 17:00:04 ks35958 email2trac: File "/usr/bin/email2trac", line 1049, in attachments url_filename = urllib.quote(filename) Mar 10 17:00:04 ks35958 email2trac: File "urllib.py", line 1110, in quote res = map(safe_map.getitem, s) Mar 10 17:00:04 ks35958 email2trac: KeyError?: u'\xfc' }

The ticket is created, but the attachment is not added.

Tracking down the error leads to an python-error in 2.4. The routine "quote", trying to encode special characters in the filename as "%<##>", returns an KeyError? with "\xfc" (ü).

http://bugs.python.org/issue3300

However: Is there possible workaround usin another python-function?

We use a trunk-version (218) of Version 0.30

P.S.: in another environment, we are using email2trac version 0.80 with python 2.5 under windows... Under this circumstances, there is no ticket createt at all...

sorry, that is not possible.

But you can reproduce the problem with any attachment containing an ü in the filename.

So teh trac version currently installed can also not handle an attachment with this speical character.

I just need a raw email message. So i can test it.

comment:5 Changed 15 years ago by bas

Sorry but now i remember it, can you test teh trunk version, see changelog

  * Error in urllib.quote(filename) could not handle unicode 
    filenames, closes #138
    Reported by: debacle at debian dot org
    Applied  by: Bas van der Vlies

comment:6 Changed 15 years ago by anonymous

looking at the ticket #138 seems good.

Sorry for duplicating the error. I was searching for it but i didn't found it. We will test this trunk version.

  • Resolution set to duplicate
  • Status changed from assigned to closed

Introducing this little patch in our "old" trunk version fixes the problem as far as the Ü is translated to %C3%BC

The attachment ist there - the problem ist fixed. Beautification may be done later...
