Raw Blame History

0.6.0

Warning

Backward incompatible changes:

  • 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):)
  • Column.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 migrate.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 ~migrate.changeset.constraint.UniqueConstraint/~migrate.changeset.constraint.CheckConstraint and corresponding create/drop methods
  • API url parameter can also be an Engine 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 Column.create <migrate.changeset.schema.ChangesetColumn.create> which issues corresponding UPDATE statements to set defaults after column creation
  • Column.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

Bug fixes

  • server_defaults passed to Column.create <migrate.changeset.schema.ChangesetColumn.create> are now issued correctly
  • use SQLAlchemy quoting system to avoid name conflicts (for issue 32)
  • complete refactoring of ~migrate.changeset.schema.ColumnDelta (fixes issue 23)
  • partial refactoring of changeset package
  • fixed bug when Column.alter <migrate.changeset.schema.ChangesetColumn.alter>(server_default='string') was not properly set
  • constraints passed to Column.create <migrate.changeset.schema.ChangesetColumn.create> are correctly interpreted (ALTER TABLE ADD CONSTRAINT is issued after ATLER TABLE ADD COLUMN)
