do you have a test case for this ? the proxy_engine unit tests all pass (i.e. lets add this failure case as well).
Im not sure how "object.getattr(self, "__dict__")" changes anything vs. self.__dict__ (since the __getattr__ should only be called for non-existent attributes), or how this error is occuring since it seems to only be looking up "_engine" which was set in the constructor. dmiller wrote: > I got this error after updating sqlalchemy today: > > File "/Users/dmiller/Code/PyOE/src/orderentry/model.py", line 394, > in ? > assign_mapper(Value, value, properties=dict(alias=sa.relation > (Alias))) > File "/Users/dmiller/Code/SQLAlchemy/lib/sqlalchemy/mapping/ > __init__.py", line 114, in assign_mapper > m = mapper(class_, *args, **params) > File "/Users/dmiller/Code/SQLAlchemy/lib/sqlalchemy/mapping/ > __init__.py", line 49, in mapper > return Mapper(class_, table, *args, **params) > File "/Users/dmiller/Code/SQLAlchemy/lib/sqlalchemy/mapping/ > mapper.py", line 175, in __init__ > prop.init(key, self) > File "/Users/dmiller/Code/SQLAlchemy/lib/sqlalchemy/mapping/ > mapper.py", line 770, in init > self.do_init(key, parent) > File "/Users/dmiller/Code/SQLAlchemy/lib/sqlalchemy/mapping/ > properties.py", line 175, in do_init > self.primaryjoin = sql.join(parent.table, self.target).onclause > File "/Users/dmiller/Code/SQLAlchemy/lib/sqlalchemy/sql.py", line > 41, in join > return Join(left, right, onclause, **kwargs) > File "/Users/dmiller/Code/SQLAlchemy/lib/sqlalchemy/sql.py", line > 834, in __init__ > self.onclause = self._match_primaries(left, right) > File "/Users/dmiller/Code/SQLAlchemy/lib/sqlalchemy/sql.py", line > 851, in _match_primaries > if fk.references(primary): > File "/Users/dmiller/Code/SQLAlchemy/lib/sqlalchemy/schema.py", > line 369, in references > return table._get_col_by_original(self.column) is not None > File "/Users/dmiller/Code/SQLAlchemy/lib/sqlalchemy/sql.py", line > 570, in _get_col_by_original > return self.original_columns.get(column.original, None) > File "/Users/dmiller/Code/SQLAlchemy/lib/sqlalchemy/sql.py", line > 1070, in _orig_columns > return self._orig_cols > File "/Users/dmiller/Code/SQLAlchemy/lib/sqlalchemy/ext/proxy.py", > line 122, in __getattr__ > return getattr(self._get_impl(), key) > File "/Users/dmiller/Code/SQLAlchemy/lib/sqlalchemy/ext/proxy.py", > line 114, in _get_impl > e = self.engine > File "/Users/dmiller/Code/SQLAlchemy/lib/sqlalchemy/ext/proxy.py", > line 122, in __getattr__ > return getattr(self._get_impl(), key) > File "/Users/dmiller/Code/SQLAlchemy/lib/sqlalchemy/ext/proxy.py", > line 114, in _get_impl > e = self.engine > > ... many more recursions ... > > File "/Users/dmiller/Code/SQLAlchemy/lib/sqlalchemy/ext/proxy.py", > line 122, in __getattr__ > return getattr(self._get_impl(), key) > File "/Users/dmiller/Code/SQLAlchemy/lib/sqlalchemy/ext/proxy.py", > line 114, in _get_impl > e = self.engine > File "/Users/dmiller/Code/SQLAlchemy/lib/sqlalchemy/ext/proxy.py", > line 124, in <lambda> > engine = property(lambda self: self._engine.engine) > File "/Users/dmiller/Code/SQLAlchemy/lib/sqlalchemy/ext/proxy.py", > line 82, in __getattr__ > if self.get_engine() is not None: > File "/Users/dmiller/Code/SQLAlchemy/lib/sqlalchemy/ext/proxy.py", > line 43, in get_engine > if self.storage.engine is None: > RuntimeError: maximum recursion depth exceeded > > > This fixed it, although not elegantly (too many lookups going on, > which is expensive in Python): > > class ProxyTableImpl(sql.TableImpl): > > ... other methods omitted ... > > def __getattr__(self, key): > d = object.getattr(self, "__dict__") > if key in d: > return d[key] > return getattr(self._get_impl(), key) > > > ~ Daniel > > > > ------------------------------------------------------- > This SF.net email is sponsored by: Splunk Inc.
