Message: Logged In: YES user_id=1123998 The thing I missed in trying to duplicate is the fact that the exception is thrown in decode_rfc2231(). Thus, the problem only occurs with a RFC2231 encoded header, i.e., one with a long filename split into pieces as filename*0="first part of name containing ' character" filename*1="second part of name - etc." The underlying problem is in the Python email library in email/Utils.py. See http://mail.python.org/pipermail/email-sig/2006-July/000293.html for a more complete description and a potential fix. ---------------------------------------------------------------------- Comment By: Mark Sapiro (msapiro) Date: 2006-04-14 10:39 Message: Logged In: YES user_id=1123998 I am unable to duplicate this error with various versions of Python's email library. I am using an attachment with the header Content-Disposition: attachment; filename="cal'dar.doc" If the one that fails in your case is different from this in any significant way, please post it. ---------------------------------------------------------------------- Comment By: cpkevin (xprt5) Date: 2006-04-14 06:07 Message: Logged In: YES user_id=1501592 Here is the latest traceback Apr 11 23:04:22 2006 (60899) Uncaught runner exception: need more than 2 values to unpack Apr 11 23:04:22 2006 (60899) Traceback (most recent call last): File "/usr/local/cpanel/3rdparty/mailman/Mailman/Queue/Runner.py", line 111, in _oneloop self._onefile(msg, msgdata) File "/usr/local/cpanel/3rdparty/mailman/Mailman/Queue/Runner.py", line 167, in _onefile keepqueued = self._dispose(mlist, msg, msgdata) File "/usr/local/cpanel/3rdparty/mailman/Mailman/Queue/IncomingRunner.py", line 130, in _dispose more = self._dopipeline(mlist, msg, msgdata, pipeline) File "/usr/local/cpanel/3rdparty/mailman/Mailman/Queue/IncomingRunner.py", line 153, in _dopipeline sys.modules[modname].process(mlist, msg, msgdata) File "/usr/local/cpanel/3rdparty/mailman/Mailman/Handlers/ToDigest.py", line 92, in process send_digests(mlist, mboxfp) File "/usr/local/cpanel/3rdparty/mailman/Mailman/Handlers/ToDigest.py", line 133, in send_digests send_i18n_digests(mlist, mboxfp) File "/usr/local/cpanel/3rdparty/mailman/Mailman/Handlers/ToDigest.py", line 315, in send_i18n_digests msg = scrubber(mlist, msg) File "/usr/local/cpanel/3rdparty/mailman/Mailman/Handlers/Scrubber.py", line 299, in process url = save_attachment(mlist, part, dir) File "/usr/local/cpanel/3rdparty/mailman/Mailman/Handlers/Scrubber.py", line 411, in save_attachment filename = Utils.oneline(msg.get_filename(''), lcset) File "/usr/local/cpanel/3rdparty/mailman/pythonlib/email/Message.py", line 724, in get_filename filename = self.get_param('filename', missing, 'content-disposition') File "/usr/local/cpanel/3rdparty/mailman/pythonlib/email/Message.py", line 607, in get_param for k, v in self._get_params_preserve(failobj, header): File "/usr/local/cpanel/3rdparty/mailman/pythonlib/email/Message.py", line 554, in _get_params_preserve params = Utils.decode_params(params) File "/usr/local/cpanel/3rdparty/mailman/pythonlib/email/Utils.py", line 337, in decode_params charset, language, value = decode_rfc2231(EMPTYSTRING.join(value)) File "/usr/local/cpanel/3rdparty/mailman/pythonlib/email/Utils.py", line 284, in decode_rfc2231 charset, language, s = parts ValueError: need more than 2 values to unpack Apr 11 23:04:22 2006 (60899) SHUNTING: 1144789462.1552839+7ff91a627d48daa19efc8509d86eb3ec869fc909 ---------------------------------------------------------------------- Comment By: Mark Sapiro (msapiro) Date: 2006-04-13 20:34 Message: Logged In: YES user_id=1123998 I'm not sure if this is a 2.1.6 bug or a cPanel bug, but it seems to be fine in 2.1.7 since I have now received copies of this bug report, its two updates, the 149967 report and its update (a total of 5 messages) from the mailman-coders@python.org Mailman 2.1.7 list, and they all have subject [ mailman-Bugs-1469962 ] Attachments with ' just hang (or the same with 1469967). I.e., the same messages you receive directly from sourceforge.net are also posted to mailman-coders@python.org. In any case, if you want to post the full traceback from the error, either here or directly to me, I will try to determine the problem and suggest a fix for 2.1.6. ---------------------------------------------------------------------- Comment By: cpkevin (xprt5) Date: 2006-04-13 19:22 Message: Logged In: YES user_id=1501592 Mailman version is 2.1.6 ---------------------------------------------------------------------- Comment By: Mark Sapiro (msapiro) Date: 2006-04-13 18:36 Message: Logged In: YES user_id=1123998 What Mailman/Python version is this?
