details: http://hg.sqlalchemy.org/sqlalchemy/sqlalchemy/rev/9ec42b8c28ae changeset: 8429:9ec42b8c28ae user: Mike Bayer <mi...@zz...> date: Sat Jun 30 12:14:59 2012 -0400 description: - using sublime, so there's mass trailing whitespace removal - port from 0.8: Fixed bug whereby a disconnect detect + dispose that occurs when the QueuePool has threads waiting for connections would leave those threads waiting for the duration of the timeout on the old pool (or indefinitely if timeout was disabled). The fix now notifies those waiters with a special exception case and has them move onto the new pool.

SQLAlchemy 0.8 now targets Python 2.5 and + above. Python 2.4 is no longer supported. + + - [removed] The "sqlalchemy.exceptions" + synonym for "sqlalchemy.exc" is removed + fully. [ticket:2433] + +- orm + - [removed] The legacy "mutable" system of the + ORM, including the MutableType class as well + as the mutable=True flag on PickleType + and postgresql.ARRAY has been removed. + In-place mutations are detected by the ORM + using the sqlalchemy.ext.mutable extension, + introduced in 0.7. The removal of MutableType + and associated constructs removes a great + deal of complexity from SQLAlchemy's internals. + The approach performed poorly as it would incur + a scan of the full contents of the Session + when in use. [ticket:2442] + + - [moved] The InstrumentationManager interface + and the entire related system of alternate + class implementation is now moved out + to sqlalchemy.ext.instrumentation. This is + a seldom used system that adds significant + complexity and overhead to the mechanics of + class instrumentation. The new architecture + allows it to remain unused until + InstrumentationManager is actually imported, + at which point it is bootstrapped into + the core. + + - [feature] Major rewrite of relationship() + internals now allow join conditions which + include columns pointing to themselves + within composite foreign keys. A new + API for very specialized primaryjoin conditions + is added, allowing conditions based on + SQL functions, CAST, etc. to be handled + by placing the annotation functions + remote() and foreign() inline within the + expression when necessary. Previous recipes + using the semi-private _local_remote_pairs + approach can be upgraded to this new + approach. [ticket:1401] + + - [feature] New standalone function with_polymorphic() + provides the functionality of query.with_polymorphic() + in a standalone form. It can be applied to any + entity within a query, including as the target + of a join in place of the "of_type()" modifier. + [ticket:2333] + + - [feature] The of_type() construct on attributes + now accepts aliased() class constructs as well + as with_polymorphic constructs, and works with + query.join(), any(), has(), and also + eager loaders subqueryload(), joinedload(), + contains_eager() + [ticket:2438] [ticket:1106] + + - [feature] The "deferred declarative + reflection" system has been moved into the + declarative extension itself, using the + new DeferredReflection class. This + class is now tested with both single + and joined table inheritance use cases. + [ticket:2485] + + - [feature] Added new core function "inspect()", + which serves as a generic gateway to + introspection into mappers, objects, + others. The Mapper and InstanceState + objects have been enhanced with a public + API that allows inspection of mapped + attributes, including filters for column-bound + or relationship-bound properties, inspection + of current object state, history of + attributes, etc. [ticket:2208] + + - [feature] Calling rollback() within a + session.begin_nested() will now only expire + those objects that had net changes within the + scope of that transaction, that is objects which + were dirty or were modified on a flush. This + allows the typical use case for begin_nested(), + that of altering a small subset of objects, to + leave in place the data from the larger enclosing + set of objects that weren't modified in + that sub-transaction. [ticket:2452] + + - [feature] Added utility feature + Session.enable_relationship_loading(), + supersedes relationship.load_on_pending. + Both features should be avoided, however. + [ticket:2372] + + - [bug] The "passive" flag on Session.is_modified() + no longer has any effect. is_modified() in + all cases looks only at local in-memory + modified flags and will not emit any + SQL or invoke loader callables/initializers. + [ticket:2320] + + - [bug] The warning emitted when using + delete-orphan cascade with one-to-many + or many-to-many without single-parent=True + is now an error. The ORM + would fail to function subsequent to this + warning in any case. [ticket:2405] + + - [feature] Query now "auto correlates" by + default in the same way as select() does. + Previously, a Query used as a subquery + in another would require the correlate() + method be called explicitly in order to + correlate a table on the inside to the + outside. As always, correlate(None) + disables correlation. [ticket:2179] + + - [feature] The after_attach event is now + emitted after the object is established + in Session.new or Session.identity_map + upon Session.add(), Session.merge(), + etc., so that the object is represented + in these collections when the event + is called. Added before_attach + event to accommodate use cases that + need autoflush w pre-attached object. + [ticket:2464] + + - [removed] Deprecated identifiers removed: + + * allow_null_pks mapper() argument + (use allow_partial_pks) + + * _get_col_to_prop() mapper method + (use get_property_by_column()) + + * dont_load argument to Session.merge() + (use load=True) + + * sqlalchemy.orm.shard module + (use sqlalchemy.ext.horizontal_shard) + +- engine + - [bug] Fixed bug whereby if a database restart + affected multiple connections, each + connection would individually invoke a new + disposal of the pool, even though only + one disposal is needed. [ticket:2522] + + - [feature] Added a new system + for registration of new dialects in-process + without using an entrypoint. See the + docs for "Registering New Dialects". + [ticket:2462] + + - [bug] The names of the columns on the + .c. attribute of a select().apply_labels() + is now based on <tablename>_<colkey> instead + of <tablename>_<colname>, for those columns + that have a distinctly named .key. + [ticket:2397] + + - [feature] Inspector.get_primary_keys() is + deprecated; use Inspector.get_pk_constraint(). + Courtesy Diana Clarke. [ticket:2422] + + - [bug] The autoload_replace flag on Table, + when False, will cause any reflected foreign key + constraints which refer to already-declared + columns to be skipped, assuming that the + in-Python declared column will take over + the task of specifying in-Python ForeignKey + or ForeignKeyConstraint declarations. + + - [bug] The ResultProxy methods inserted_primary_key, + last_updated_params(), last_inserted_params(), + postfetch_cols(), prefetch_cols() all + assert that the given statement is a compiled + construct, and is an insert() or update() + statement as is appropriate, else + raise InvalidRequestError. [ticket:2498] + + - ResultProxy.last_inserted_ids is removed, + replaced by inserted_primary_key. + +- sql + - [feature] The Inspector object can now be + acquired using the new inspect() service, + part of [ticket:2208] + + - [feature] The column_reflect event now + accepts the Inspector object as the first + argument, preceding "table". Code which + uses the 0.7 version of this very new + event will need modification to add the + "inspector" object as the first argument. + [ticket:2418] + + - [feature] The behavior of column targeting + in result sets is now case sensitive by + default. SQLAlchemy for many years would + run a case-insensitive conversion on these values, + probably to alleviate early case sensitivity + issues with dialects like Oracle and + Firebird. These issues have been more cleanly + solved in more modern versions so the performance + hit of calling lower() on identifiers is removed. + The case insensitive comparisons can be re-enabled + by setting "case_insensitive=False" on + create_engine(). [ticket:2423] + + - [feature] The "unconsumed column names" warning emitted + when keys are present in insert.values() or update.values() + that aren't in the target table is now an exception. + [ticket:2415] + + - [feature] Added "MATCH" clause to ForeignKey, + ForeignKeyConstraint, courtesy Ryan Kelly. + [ticket:2502] + + - [feature] Added support for DELETE and UPDATE from + an alias of a table, which would assumedly + be related to itself elsewhere in the query, + courtesy Ryan Kelly. [ticket:2507] + + - [feature] select() features a correlate_except() + method, auto correlates all selectables except those + passed. + + - [bug] All of UniqueConstraint, ForeignKeyConstraint, + CheckConstraint, and PrimaryKeyConstraint will + attach themselves to their parent table automatically + when they refer to a Table-bound Column object directly + (i.e. not just string column name), and refer to + one and only one Table. Prior to 0.8 this behavior + occurred for UniqueConstraint and PrimaryKeyConstraint, + but not ForeignKeyConstraint or CheckConstraint. + [ticket:2410] + + - [bug] column.label(None) now produces an + anonymous label, instead of returning the + column object itself, consistent with the behavior + of label(column, None). [ticket:2168] + +- sqlite + - [feature] the SQLite date and time types + have been overhauled to support a more open + ended format for input and output, using + name based format strings and regexps. A + new argument "microseconds" also provides + the option to omit the "microseconds" + portion of timestamps. Thanks to + Nathan Wright for the work and tests on + this. [ticket:2363] + +- mssql + - [bug] removed legacy behavior whereby + a column comparison to a scalar SELECT via + == would coerce to an IN with the SQL server + dialect. This is implicit + behavior which fails in other scenarios + so is removed. Code which relies on this + needs to be modified to use column.in_(select) + explicitly. [ticket:2277] + +- postgresql + + - [feature] postgresql.ARRAY features an optional + "dimension" argument, will assign a specific + number of dimensions to the array which will + render in DDL as ARRAY[][]..., also improves + performance of bind/result processing. |
