0.3.5

0.3.5

Released: Sun Jul 08 2012

• [bug] Fixed issue whereby reflected server defaults
  wouldn't be quoted correctly; uses repr() now.

  References: #31

• [bug] Fixed issue whereby when autogenerate would
  render create_table() on the upgrade side for a
  table that has a Boolean type, an unnecessary
  CheckConstraint() would be generated.

  References: #58

• [feature] Implemented SQL rendering for
  CheckConstraint() within autogenerate upgrade,
  including for literal SQL as well as SQL Expression
  Language expressions.

0.3.4

0.3.4

Released: Sat Jun 02 2012

• [bug] Fixed command-line bug introduced by the
  "revision_environment" feature.

0.3.3

0.3.3

Released: Sat Jun 02 2012

• [feature] New config argument
  "revision_environment=true", causes env.py to
  be run unconditionally when the "revision" command
  is run, to support script.py.mako templates with
  dependencies on custom "template_args".

• [feature] Added "template_args" option to configure()
  so that an env.py can add additional arguments
  to the template context when running the
  "revision" command. This requires either --autogenerate
  or the configuration directive "revision_environment=true".

• [bug] Added "type" argument to op.drop_constraint(),
  and implemented full constraint drop support for
  MySQL. CHECK and undefined raise an error.
  MySQL needs the constraint type
  in order to emit a DROP CONSTRAINT.

  References: #44

• [feature] Added version_table argument to
  EnvironmentContext.configure(), allowing for the
  configuration of the version table name.

  References: #34

• [feature] Added support for "relative" migration
  identifiers, i.e. "alembic upgrade +2",
  "alembic downgrade -1". Courtesy
  Atsushi Odagiri for this feature.

• [bug] Fixed bug whereby directories inside of
  the template directories, such as pycache
  on Pypy, would mistakenly be interpreted as
  files which are part of the template.

0.3.2

0.3.2

Released: Mon Apr 30 2012

• [feature] Basic support for Oracle added,
  courtesy shgoh.

• [feature] Added support for UniqueConstraint
  in autogenerate, courtesy Atsushi Odagiri

• [bug] Fixed support of schema-qualified
  ForeignKey target in column alter operations,
  courtesy Alexander Kolov.

• [bug] Fixed bug whereby create_unique_constraint()
  would include in the constraint columns that
  are added to all Table objects using events,
  externally to the generation of the constraint.

0.3.1

0.3.1

Released: Sat Apr 07 2012

• [bug] bulk_insert() fixes:

  -   bulk_insert() operation was
      not working most likely since the 0.2 series
      when used with an engine.
  
  -   Repaired bulk_insert() to complete when
      used against a lower-case-t table and executing
      with only one set of parameters, working
      around SQLAlchemy bug #2461 in this regard.
  
  -   bulk_insert() uses "inline=True" so that phrases
      like RETURNING and such don't get invoked for
      single-row bulk inserts.
  
  -   bulk_insert() will check that you're passing
      a list of dictionaries in, raises TypeError
      if not detected.

0.3.0

0.3.0

Released: Thu Apr 05 2012

• [general] The focus of 0.3 is to clean up
  and more fully document the public API of Alembic,
  including better accessors on the MigrationContext
  and ScriptDirectory objects. Methods that are
  not considered to be public on these objects have
  been underscored, and methods which should be public
  have been cleaned up and documented, including:

  MigrationContext.get_current_revision()
  ScriptDirectory.iterate_revisions()
  ScriptDirectory.get_current_head()
  ScriptDirectory.get_heads()
  ScriptDirectory.get_base()
  ScriptDirectory.generate_revision()

• [feature] Added a bit of autogenerate to the
  public API in the form of the function
  alembic.autogenerate.compare_metadata.

0.2.2

0.2.2

Released: Mon Mar 12 2012

• [feature] Informative error message when op.XYZ
  directives are invoked at module import time.

• [bug] Fixed inappropriate direct call to
  util.err() and therefore sys.exit()
  when Config failed to locate the
  config file within library usage.

  References: #35

• [bug] Autogenerate will emit CREATE TABLE
  and DROP TABLE directives according to
  foreign key dependency order.

• [bug] implement 'tablename' parameter on
  drop_index() as this is needed by some
  backends.

• [feature] Added execution_options parameter
  to op.execute(), will call execution_options()
  on the Connection before executing.

  The immediate use case here is to allow
  access to the new no_parameters option
  in SQLAlchemy 0.7.6, which allows
  some DBAPIs (psycopg2, MySQLdb) to allow
  percent signs straight through without
  escaping, thus providing cross-compatible
  operation with DBAPI execution and
  static script generation.

• [bug] setup.py won't install argparse if on
  Python 2.7/3.2

• [feature] script_location can be interpreted
  by pkg_resources.resource_filename(), if
  it is a non-absolute URI that contains
  colons. This scheme is the same
  one used by Pyramid.

  References: #29

• [feature] added missing support for
  onupdate/ondelete flags for
  ForeignKeyConstraint, courtesy Giacomo Bagnoli

• [bug] fixed a regression regarding an autogenerate
  error message, as well as various glitches
  in the Pylons sample template. The Pylons sample
  template requires that you tell it where to
  get the Engine from now. courtesy
  Marcin Kuzminski

  References: #30

• [bug] drop_index() ensures a dummy column
  is added when it calls "Index", as SQLAlchemy
  0.7.6 will warn on index with no column names.

0.2.1

0.2.1

Released: Tue Jan 31 2012

• [bug] Fixed the generation of CHECK constraint,
  regression from 0.2.0

  References: #26

0.2.0

0.2.0

Released: Mon Jan 30 2012

• [feature] API rearrangement allows everything
  Alembic does to be represented by contextual
  objects, including EnvironmentContext,
  MigrationContext, and Operations. Other
  libraries and applications can now use
  things like "alembic.op" without relying
  upon global configuration variables.
  The rearrangement was done such that
  existing migrations should be OK,
  as long as they use the pattern
  of "from alembic import context" and
  "from alembic import op", as these
  are now contextual objects, not modules.

  References: #19

• [feature] The naming of revision files can
  now be customized to be some combination
  of "rev id" and "slug", the latter of which
  is based on the revision message.
  By default, the pattern "_"
  is used for new files. New script files
  should include the "revision" variable
  for this to work, which is part of
  the newer script.py.mako scripts.

  References: #24

• [bug] env.py templates call
  connection.close() to better support
  programmatic usage of commands; use
  NullPool in conjunction with create_engine()
  as well so that no connection resources
  remain afterwards.

  References: #25

• [bug] fix the config.main() function to honor
  the arguments passed, remove no longer used
  "scripts/alembic" as setuptools creates this
  for us.

  References: #22

• [bug] Fixed alteration of column type on
  MSSQL to not include the keyword "TYPE".

• [feature] Can create alembic.config.Config
  with no filename, use set_main_option()
  to add values. Also added set_section_option()
  which will add sections.

0.1.1

Released: Wed Jan 04 2012

• [bug] Clean up file write operations so that
  file handles are closed.

• [feature] PyPy is supported.

• [feature] Python 2.5 is supported, needs
  future.with_statement

• [bug] Fix autogenerate so that "pass" is
  generated between the two comments
  if no net migrations were present.

• [bug] Fix autogenerate bug that prevented
  correct reflection of a foreign-key
  referenced table in the list of "to remove".

  References: #16

• [bug] Fix bug where create_table() didn't
  handle self-referential foreign key
  correctly

  References: #17

• [bug] Default prefix for autogenerate
  directives is "op.", matching the
  mako templates.

  References: #18

• [feature] Add alembic_module_prefix argument
  to configure() to complement
  sqlalchemy_module_prefix.

  References: #18

• [bug] fix quotes not being rendered in
  ForeignKeConstraint during
  autogenerate
