0.8.4

Released: December 15, 2015

  • [feature] [versioning] A major improvement to the hash id generation function, which for some
    reason used an awkward arithmetic formula against uuid4() that produced
    values that tended to start with the digits 1-4. Replaced with a
    simple substring approach which provides an even distribution. Pull
    request courtesy Antti Haapala.

  • [autogenerate] [feature] Added an autogenerate renderer for the ExecuteSQLOp operation
    object; only renders if given a plain SQL string, otherwise raises
    NotImplementedError. Can be of help with custom autogenerate
    sequences that includes straight SQL execution. Pull request courtesy
    Jacob Magnusson.

  • [batch] [bug] Batch mode generates a FOREIGN KEY constraint that is self-referential
    using the ultimate table name, rather than _alembic_batch_temp.
    When the table is renamed from _alembic_batch_temp back to the
    original name, the FK now points to the right name. This
    will not work if referential integrity is being enforced (eg. SQLite
    "PRAGMA FOREIGN_KEYS=ON") since the original table is dropped and
    the new table then renamed to that name, however this is now consistent
    with how foreign key constraints on other tables already operate
    with batch mode; these don't support batch mode if referential integrity
    is enabled in any case.

  • [autogenerate] [bug] Added a type-level comparator that distinguishes Integer,
    BigInteger, and SmallInteger types and
    dialect-specific types; these all have "Integer" affinity so previously
    all compared as the same.

  • [batch] [bug] Fixed bug where the server_default parameter of alter_column()
    would not function correctly in batch mode.

  • [autogenerate] [bug] Adjusted the rendering for index expressions such that a Column
    object present in the source Index will not be rendered
    as table-qualified; e.g. the column name will be rendered alone.
    Table-qualified names here were failing on systems such as Postgresql.
