0.5rc4 is out, I wanted to get it out quickly since people were hitting a garbage-collection bug that was introduced in 0.5rc3. I'm using rc4 on a production site right now so I'm pretty confident that it's quite solid and hopefully I won't start changing more things before an 0.5.0 final.
This is also the best performing SQLA we've had to date. Expect a tad more pep in your applications :). Download SQLAlchemy 0.5rc4 at: http://www.sqlalchemy.org/download.html 0.5.0rc4 ======== - features - orm - Query.count() has been enhanced to do the "right thing" in a wider variety of cases. It can now count multiple-entity queries, as well as column-based queries. Note that this means if you say query(A, B).count() without any joining criterion, it's going to count the cartesian product of A*B. Any query which is against column-based entities will automatically issue "SELECT count(1) FROM (SELECT...)" so that the real rowcount is returned, meaning a query such as query(func.count(A.name)).count() will return a value of one, since that query would return one row. - Lots of performance tuning. A rough guesstimate over various ORM operations places it 10% faster over 0.5.0rc3, 25-30% over 0.4.8. - bugfixes and behavioral changes - general: - global "propigate"->"propagate" change. - orm - Adjustments to the enhanced garbage collection on InstanceState to better guard against errors due to lost state. - Query.get() returns a more informative error message when executed against multiple entities. [ticket:1220] - Restored NotImplementedError on Cls.relation.in_() [ticket:1140] [ticket:1221] - Fixed PendingDeprecationWarning involving order_by parameter on relation(). [ticket:1226] - sql - Removed the 'properties' attribute of the Connection object, Connection.info should be used. - Restored "active rowcount" fetch before ResultProxy autocloses the cursor. This was removed in 0.5rc3. - Rearranged the `load_dialect_impl()` method in `TypeDecorator` such that it will take effect even if the user-defined `TypeDecorator` uses another `TypeDecorator` as its impl. - access - Added support for Currency type. - Functions were not return their result. [ticket:1017] - Corrected problem with joins. Access only support LEFT OUTER or INNER not just JOIN by itself. [ticket:1017] - mssql - Lots of cleanup and fixes to correct problems with limit and offset. - Correct situation where subqueries as part of a binary expression need to be translated to use the IN and NOT IN syntax. - Fixed E Notation issue that prevented the ability to insert decimal values less than 1E-6. [ticket:1216] - Corrected problems with reflection when dealing with schemas, particularly when those schemas are the default schema. [ticket:1217] - Corrected problem with casting a zero length item to a varchar. It now correctly adjusts the CAST. - ext - Can now use a custom "inherit_condition" in __mapper_args__ when using declarative. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
