* - schema.copy() functions will copy dispatch, but only for those eventsMike Bayer2011-02-011-5/+16
| | | | | | | | | added with propagate=True. needs tests - oracle/fb test schema uses event w/ propagate=True to apply Sequence to primary key columns with test_needs_autoincrement. this does actually test the propagate=True flag a bit since it's needed in the declarative mixin tests where the 'id' column is copied.
* - SchemaItem, SchemaType now descend from common typeMike Bayer2011-01-301-38/+23
| | | | | | | | | | | | | | | | | | SchemaEventTarget, which supplies dispatch - the dispatch now provides before_parent_attach(), after_parent_attach(), events which generally bound the _set_parent() event. [ticket:2037] - the _on_table_attach mechanism now usually uses the event dispatch - fixed class-level event dispatch to propagate to all subclasses, not just immediate subclasses - fixed class-level event unpickling to handle more involved inheritance hierarchies, needed by the new schema event dispatch. - ForeignKeyConstraint doesn't re-call the column attach event on ForeignKey objects that are already associated with the correct Column - we still need that ImportError on mysqldb CLIENT FLAGS to support mock DBAPIs
* - Column.copy(), as used in table.tometadata(), copies theMike Bayer2011-01-301-0/+1
| | | | 'doc' attribute. [ticket:2028]
* rename 'frozendict' to 'immutabledict', since 'frozen' implies hashabilityMike Bayer2011-01-201-1/+1
| | | | | like frozenset which isn't really the purpose of 'immutabledict' (could be someday, in which case, we'd change the name back :) )
* - getting slightly more consistent behavior for the edge case of pk columnsMike Bayer2011-01-151-6/+7
| | | | | | with server default - autoincrement is now false with any server_default, so these all return None, applies consistency to [ticket:2020], [ticket:2021]. if prefetch is desired a "default" should be used instead of server_default.
* - dont count server_default absense as part of autoincrement, PGMike Bayer2011-01-121-3/+5
| | | | | | will have a value here upon reflection. - mysql, others will have to check "server_default" when rendering special keywords like AUTOINCREMENT
* - A TypeDecorator of Integer can be used with a primary keyMike Bayer2011-01-111-3/+4
| | | | | | | | | | | | | | | | | | | column, and the "autoincrement" feature of various dialects as well as the "sqlite_autoincrement" flag will honor the underlying database type as being Integer-based. [ticket:2005] - Result-row processors are applied to pre-executed SQL defaults, as well as cursor.lastrowid, when determining the contents of result.inserted_primary_key. [ticket:2006] - Bind parameters present in the "columns clause" of a select are now auto-labeled like other "anonymous" clauses, which among other things allows their "type" to be meaningful when the row is fetched, as in result row processors. - TypeDecorator is present in the "sqlalchemy" import space.
* - merge r43460573c27a:4993c7eae8e5d117ff342bdc59f3b0635b898e2c of 0.6 branchMike Bayer2011-01-081-1/+5

| | | | | | | | | | | | | | | | | | cuts down on clutter, timeit says there's a teeny performance gain, at least where the access is compared against attr.subattr. these aren't super-critical calls anyway - slight inlining in _class_to_mapper

The truncation only takes place with the auto-generated name, not one that is user-defined (an error would be raised instead), and the truncation scheme itself is now based on a fragment of an md5 hash of the identifier name, so that multiple indexes on columns with similar names still have unique names.
