email2trac bombs when attachment contains umlaut characters

[karsten.rohrbach@…]

From bounce message produced by postfix MTA:

TD: saving email to /tmp/tmpKadtCi.email2trac 
TD:   writing body to /tmp/tmpsgE73w.email2trac 
TD: part1: Content-Type:   application/octet-stream Traceback (most recent call last):
   File   "/usr/bin/email2trac", line 2151, in <module>   tktparser.save_email_for_debug(m, True)
   File "/usr/bin/email2trac", line   575, in save_email_for_debug
     self.debug_attachments(message_parts)
   File "/usr/bin/email2trac", line 519, in debug_attachments
     print 'TD:   part%d: filename: %s' % (n, filename) 
UnicodeEncodeError: 'ascii' codec   can't encode character u'\xc4' in position 33: ordinal not in range(128)

The filename causing this behaviour is AUFTRAGSBESTÄTIGUNGS-FORMULAR_115886.PDF, containing a German umlaut.

Deployed Version of email2trac is 1.4.3

Thanks for reporting. Is the debug option enabled in /etc/email2trac.conf? If yes then disabled it and everything should be oke

[karsten.rohrbach@…]

/etc/email2trac.conf?

[DEFAULT]
project: /srv/trac/test
debug: 0
...

[bas]

Is there nothing in the syslog. This function is only called when debug is set or bug in email2trac is triggered. It wil try to save the message and attachments.

(In [376]) Fixed some UnicodeEncodeErrors? when in debug mode, see #206.

Thanks for implementing the quick workaraound.

Now it bombs at a different stage:

TD: saving email to /tmp/tmpne8lNJ.email2trac
 TD:   writing body to /tmp/tmpelQcJd.email2trac
 TD: part1: Content-Type:   application/octet-stream Filename can not be
printed due to non-ascii   characters Filename can not be printed due to
non-ascii characters
   Traceback (most recent call last):
   File "/usr/bin/email2trac", line 2159,
   in <module>
     tktparser.save_email_for_debug(m, True)
   File   "/usr/bin/email2trac", line 583, in save_email_for_debug
   self.debug_attachments(message_parts)
   File "/usr/bin/email2trac", line   542, in debug_attachments
     fx = open(part_file, 'wb')   UnicodeEncodeError: 'ascii' codec can't
encode character u'\xc4' in   position 17: ordinal not in range(128)

Perhaps handling unicode in filenames for the temporary storage of
attachments is the problem?

[bas]

(In [377]) Fixed some issues with Unicode suport for attachments, see #206

[anonymous]

Can you test this for me. I have done some testing and i think that it solves the problem.

[bas]

It is fixed in release 1.4.5

(In [383]) email2trac.py.in:

• A better fix for attachments with special characters, see #206
