0.6 (11.07.2010)

Warning

Backward incompatible changes:

• :pymigrate.versioning.api.test and schema comparison functions now all accept url as first parameter and repository as second.
• python upgrade/downgrade scripts do not import migrate_engine magically, but recieve engine as the only parameter to function (eg. def upgrade(migrate_engine):)
• :pyColumn.alter <migrate.changeset.schema.ChangesetColumn.alter> does not accept current_name anymore, it extracts name from the old column.

Features

• added support for firebird <firebird-d>
• added option to define custom templates through option --templates_path and --templates_theme, read more in tutorial section <custom-templates>
• use Python logging for output, can be shut down by passing --disable_logging to :pymigrate.versioning.shell.main
• deprecated alter_column comparing of columns. Just use explicit parameter change.
• added support for SQLAlchemy 0.6.x by Michael Bayer
• Constraint classes have cascade=True keyword argument to issue DROP CASCADE where supported
• added :py~migrate.changeset.constraint.UniqueConstraint/ :py~migrate.changeset.constraint.CheckConstraint and corresponding create/drop methods
• API url parameter can also be an :pyEngine instance (this usage is discouraged though sometimes necessary)
• code coverage is up to 80% with more than 100 tests
• alter, create, drop column / rename table / rename index constructs now accept alter_metadata parameter. If True, it will modify Column/Table objects according to changes. Otherwise, everything will be untouched.
• added populate_default bool argument to :pyColumn.create <migrate.changeset.schema.ChangesetColumn.create> which issues corresponding UPDATE statements to set defaults after column creation
• :pyColumn.create <migrate.changeset.schema.ChangesetColumn.create> accepts primary_key_name, unique_name and index_name as string value which is used as contraint name when adding a column

Fixed bugs

• ORM methods now accept connection parameter commonly used for transactions
• server_defaults passed to :pyColumn.create <migrate.changeset.schema.ChangesetColumn.create> are now issued correctly
• use SQLAlchemy quoting system to avoid name conflicts (#32)
• complete refactoring of :py~migrate.changeset.schema.ColumnDelta (#23)
• partial refactoring of :pymigrate.changeset package
• fixed bug when :pyColumn.alter <migrate.changeset.schema.ChangesetColumn.alter>(server_default='string') was not properly set
• constraints passed to :pyColumn.create <migrate.changeset.schema.ChangesetColumn.create> are correctly interpreted (ALTER TABLE ADD CONSTRAINT is issued after ATLER TABLE ADD COLUMN)
• script names don't break with dot in the name

Documentation

• dialect support <dialect-support> table was added to documentation
• major update to documentation

• added engine_dict and engine_arg* parameters to all api functions (deprecated echo) [Domen Kozar]
