[SQLObject] Problems with validators and connectionFromURI

[Cyril E. <cy...@de...>]

Hello,

We have found the following two problems:

If someone modify a property and then read it back the 'toPython' 
validator's method is _not_ called. In our case we are using a 
'UnicaodeValidator' to store Unicode strings in UTF8 into a Postgres 
database, code follows:


class UnicodeValidator(sqlobject.include.validators.Validator):

     def toPython(self, value, state=None):
         if value is None:
             return None

         return unicode(value,"utf8")

     def fromPython(self, value, state=None):
         if value is None:
             return None

         return value.encode("utf8")


Reading an object from the database from the first time correctly calls 
the validator 'toPython' method , but not after a write. Is somebody 
else having this problem? It arises even when disabling the cache. The 
'fromPython' method _seems_ to be called every time.

My second concern is with the parsing of the 'query' part in 
connectionFromURI; the values are assigned to properties as String and 
are not evaluated, for Boolean values (like enableing and disabling the 
cache) it ask for problems as setting cache=False always make a True 
value. A simple solution is to use eval before assigning the property 
inside the code of the method, but it may raise security problems. Again 
is somebody else having this problem?

If I do a patch what is the procedure to post it and make it reviewed?

All in all the library is quite impressive and I must thank the author 
for his work.
