I believe the problem is in _wordinfoget, which should return None if
the word is not in the database (and this is how _worddistanceget
decides whether to use the 'unknown token' probability).
PGClassifier's _wordinfoget method (actually the base
SQLClassifier's), which, as Kenny said, isn't widely used, is:
def _wordinfoget(self, word):
if isinstance(word, unicode):
word = word.encode("utf-8")
row = self._get_row(word)
if row:
item = self.WordInfoClass()
item.__setstate__((row["nspam"], row["nham"]))
return item
else:
return self.WordInfoClass()
I believe this should be:
def _wordinfoget(self, word):
if isinstance(word, unicode):
word = word.encode("utf-8")
row = self._get_row(word)
if row:
item = self.WordInfoClass()
item.__setstate__((row["nspam"], row["nham"]))
return item
else:
return None
(This is more-or-less what the mySQL storage option does).
Try that change (just changing the final return from
"self.WordInfoClass()" to "None"), and see if it fixes the problem.
If it does, please let us know so that we can make the change in the
repository as well.
