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] + + - [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] 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] + - [bug] Fixed issue in unit of work whereby setting a non-None self-referential many-to-one relationship to None would fail to persist the change if the former value was not already loaded. - [ticket:2477]. + [ticket:2477]. Also in 0.7.7 + + - [bug] Fixed bug in relationship comparisons + whereby calling unimplemented methods like + SomeClass.somerelationship.like() would + produce a recursion overflow, instead + of NotImplementedError. Also in 0.7.7. + + - [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] Added prefix_with() method to Query, calls upon select().prefix_with() to allow placement of MySQL SELECT directives in statements. Courtesy Diana Clarke [ticket:2443] + also in 0.7.7. - [bug] Fixed bug in 0.7.6 introduced by [ticket:2409] whereby column_mapped_collection used against columns that were mapped as joins or other indirect selectables would fail to function. + also in 0.7.7. - [feature] Added new flag to @validates include_removes. When True, collection @@ -31,56 +127,155 @@ will also be sent to the validation function, which accepts an additional argument "is_remove" when this flag is used. + also in 0.7.7. + + - [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. [ticket:2464] - [bug] Fixed bug whereby polymorphic_on column that's not otherwise mapped on the class would be incorrectly included in a merge() operation, raising an error. [ticket:2449] + also in 0.7.7. - [bug] Fixed bug in expression annotation mechanics which could lead to incorrect rendering of SELECT statements with aliases and joins, particularly when using column_property(). [ticket:2453] + also in 0.7.7. - [bug] Fixed bug which would prevent OrderingList from being pickleable [ticket:2454]. Courtesy Jeff Dairiki - - - [bug] Fixed bug in relationship comparisons - whereby calling unimplemented methods like - SomeClass.somerelationship.like() would - produce a recursion overflow, instead - of NotImplementedError. + also in 0.7.7. + +- engine + - [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] - 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] + + - [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] + - [bug] Removed warning when Index is created with no columns; while this might not be what the user intended, it is a valid use case as an Index could be a placeholder for just an index of a certain name. + also in 0.7.7. - [feature] Added new connection event dbapi_error(). Is called for all DBAPI-level errors passing the original DBAPI exception before SQLAlchemy modifies the state of the cursor. + also in 0.7.7. - [bug] If conn.begin() fails when calling "with engine.begin()", the newly acquired Connection is closed explicitly before propagating the exception onward normally. + also in 0.7.7. - [bug] Add BINARY, VARBINARY to types.__all__, - [ticket:2474] + [ticket:2474] Also in 0.7.7 + +- 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] + + - [feature] Added SQLite execution option + "sqlite_raw_colnames=True", will bypass + attempts to remove "." from column names + returned by SQLite cursor.description. + [ticket:2475] Also in 0.7.7. - 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] + - [feature] Added interim create_engine flag supports_unicode_binds to PyODBC dialect, to force whether or not the dialect passes Python unicode literals to PyODBC or not. |
