Added a conditional to the unpickling process for ORM

2013-04-23T17:23:48+00:00

mapped objects, such that if the reference to the object
were lost when the object was pickled, we don't
erroneously try to set up _sa_instance_state - fixes
a NoneType error.

Improved the behavior of instance management regarding

2013-04-20T06:45:08+00:00

the creation of strong references within the Session;
an object will no longer have an internal reference cycle
created if it's in the transient state or moves into the
detached state - the strong ref is created only when the
object is attached to a Session and is removed when the
object is detached.  This makes it somewhat safer for an
object to have a `__del__()` method, even though this is
not recommended, as relationships with backrefs produce
cycles too.  A warning has been added when a class with
a `__del__()` method is mapped.

happy new year (see #2645)

2013-01-01T18:46:21+00:00

just a pep8 pass of lib/sqlalchemy/orm/

2012-11-19T20:29:28+00:00

- use our new Cls.memoized_name._reset(self) method in place of all those dict.pop(),

2012-09-23T17:09:43+00:00

remove reset_memoized

- rename .attr to .attrs on mapper, instance state, [ticket:2569]

2012-09-22T19:46:09+00:00

don't need this is_really_none() thing anymore

2012-08-08T23:20:17+00:00

- [feature] A warning is emitted when a reference

2012-08-04T22:32:38+00:00

    to an instrumented collection is no longer
    associated with the parent class due to
    expiration/attribute refresh/collection
    replacement, but an append
    or remove operation is received on the
    now-detached collection.  [ticket:2476]

a lot of docs

2012-07-18T23:08:31+00:00

- with InstanceState more public, underscore all its methods

2012-07-18T20:43:02+00:00

that change object state as these aren't intended for public
use.
