Bug Description

After upgrading from edgy to fiesty, spambayes stopped working. Running sb_imapfilter gives this error:

kevins@aria:~$ cd /home/kevins/.spambayes/tavo;sb_imapfilter.py -c -t
  File "/usr/bin/sb_imapfilter.py", line 93
    from __future__ import generators
SyntaxError: from __future__ imports must occur at the beginning of the file
kevins@aria:~/.spambayes/tavo$

As a result, my spam filtering is completely broken and is doing nothing at all.

It looks like spambayes (sb_imapfilter) is not compatible with python 2.5, but python 2.5 has been installed as the default interpreter.

I am going to try to work around it by manually editing the #! line to point to python 2.4 specifically.

You might also try changing from __future__ import generators to import generators

The fix is to move line 93 ("from __future__ import generators") to line 2 (between the #! line and the description starting in line 3) in sb_imapfilter.py.

sb_dbexpimp.py and sb_notesfilter.py is also affected (other files might also be affected, I didn't grep all). The person fixing it might looked at sb_pop3dnd.py as this script does it right.

Thanks very much! I moved line 93 and now it runs...but I get this (after a long time):

kevins@aria:~$ cd /home/kevins/.spambayes/tavo;sb_imapfilter.py -c -t

and engine SpamBayes Engine Version 0.3 (January 2004).

Should I file it as a separate bug?

I'm making the assumption that after several months Adam had this assigned to himself for triaging and not for fixing. Working on a fix.

spambayes (1.0.4-3ubuntu2) gutsy; urgency=low

  * Update debian/patches/fix_import_future.dpatch to fix all instances
    of from future import not being at the start of the file.
    (LP: #114798)
  * Simplify debian/rules so unpatch actually works.
  * Remove dh_python from debian/rules (not needed)
  * Change maintainer to MOTU
  * Add build-dep on dpatch
