I was thinking to change isolation level in fact.

But first, I don't know how to do this with sqlalchemy, second, with default isolation level commits should work properly weather or not something were inserted or updated during commit and third, I was using nested transaction like this :

transaction = session.begin() nested = session.begin_nested() try: ..insert.. #trying to insert values to column that have UNIQUE constraint except: ..update.. nested.commit() transaction.commit()

so, I'm not sure that done everything right.

btw, there's a daemon, and have no user to watch on it.
