* - Added new option to :func:`.relationship` ``distinct_target_key``.Mike Bayer2013-10-133-5/+40
| | | | | | | | | | | | | | | | | | This enables the subquery eager loader strategy to apply a DISTINCT to the innermost SELECT subquery, to assist in the case where duplicate rows are generated by the innermost query which corresponds to this relationship (there's not yet a general solution to the issue of dupe rows within subquery eager loading, however, when joins outside of the innermost subquery produce dupes). When the flag is set to ``True``, the DISTINCT is rendered unconditionally, and when it is set to ``None``, DISTINCT is rendered if the innermost relationship targets columns that do not comprise a full primary key. The option defaults to False in 0.8 (e.g. off by default in all cases), None in 0.9 (e.g. automatic by default). Thanks to Alexander Koval for help with this.

* A performance fix related to the usage of the :func:`.defer` optionMike Bayer2013-07-134-32/+38
| | | | | | | | | | | | | when loading mapped entities. The function overhead of applying a per-object deferred callable to an instance at load time was significantly higher than that of just loading the data from the row (note that ``defer()`` is meant to reduce DB/network overhead, not necessarily function call count); the function call overhead is now less than that of loading data from the column in all cases. There is also a reduction in the number of "lazy callable" objects created per load from N (total deferred values in the result) to 1 (total number of deferred cols). [ticket:2778]

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. [ticket:2708]
