- update to 0.7.6:
  * Fixed bug where the case of multiple mergepoints that all
    have the identical set of ancestor revisions would fail to be
    upgradable, producing an assertion failure.
  * Added support for type comparison functions to be not just per
    environment, but also present on the custom types themselves, by
    supplying a method ``compare_against_backend``.
  * Fully implemented the :paramref:`~.Operations.batch_alter_table.copy_from`
    parameter for batch mode
  * Repaired support for the :meth:`.BatchOperations.create_index`
    directive, which was mis-named internally such that the operation

- update to 0.7.5.post2:
  * Added a new feature Config.attributes, to help with the use
    case of sharing state such as engines and connections on the
    outside with a series of Alembic API calls; also added a new
    cookbook section to describe this simple but pretty important
    use case.
  * The format of the default env.py script has been refined a bit;
    it now uses context managers not only for the scope of the
    transaction, but also for connectivity from the starting
    engine. The engine is also now called a “connectable” in
    support of the use case of an external connection being passed
    in.
  * Added support for “alembic stamp” to work when given “heads” as
    an argument, when multiple heads are present.
  * The --autogenerate option is not valid when used in conjunction
    with “offline” mode, e.g. --sql. This now raises a
    CommandError, rather than failing more deeply later on. Pull
    request courtesy Johannes Erdfelt.
  * Fixed bug where the mssql DROP COLUMN directive failed to
    include modifiers such as “schema” when emitting the DDL.
  * Postgresql “functional” indexes are necessarily skipped from
    the autogenerate process, as the SQLAlchemy backend currently
    does not support reflection of these structures. A warning is
    emitted both from the SQLAlchemy backend as well as from the
    Alembic backend for Postgresql when such an index is detected.
  * Fixed bug where MySQL backend would report dropped unique
    indexes and/or constraints as both at the same time. This is
    because MySQL doesn’t actually have a “unique constraint”
    construct that reports differently than a “unique index”, so it
    is present in both lists. The net effect though is that the
    MySQL backend will report a dropped unique index/constraint as
    an index in cases where the object was first created as a
    unique constraint, if no other information is available to make
    the decision. This differs from other backends like Postgresql
    which can report on unique constraints and unique indexes
    separately.
  * Fixed bug where using a partial revision identifier as the
    “starting revision” in --sql mode in a downgrade operation
    would fail to resolve properly.
- set minimum version for SQLAlchemy to 0.7.6
- use update-alternatives for alembic binary
- always run the tests when building the package

Thu Feb  5 15:04:20 UTC 2015 - tbechtold@suse.com

- update to 0.7.4:
  * Repaired issue where a server default specified without text()
  that represented a numeric or floating point (e.g. with decimal
  places) value would fail in the Postgresql-specific check for
  “compare server default”; as PG accepts the value with quotes
  in the table specification, it’s still valid. Pull request
  courtesy Dimitris Theodorou.
  * The rendering of a ForeignKeyConstraint will now ensure that
  the names of the source and target columns are the database-side
  name of each column, and not the value of the .key attribute as
  may be set only on the Python side. This is because Alembic
  generates the DDL for constraints as standalone objects without
  the need to actually refer to an in-Python Table object, so
  there’s no step that would resolve these Python-only key names
  to database column names.
  * Fixed bug in foreign key autogenerate where if the in-Python
  table used custom column keys (e.g. using the key='foo' kwarg
  to Column), the comparison of existing foreign keys to those
  specified in the metadata would fail, as the reflected table
  would not have these keys available which to match up. Foreign
  key comparison for autogenerate now ensures it’s looking at
  the database-side names of the columns in all cases; this
  matches the same functionality within unique constraints and
  indexes.
  * Fixed issue in autogenerate type rendering where types that
  belong to modules that have the name “sqlalchemy” in them would
  be mistaken as being part of the sqlalchemy. namespace. Pull
  req courtesy Bartosz Burclaf.

-------------------------------------------------------------------
Mon Jan  5 10:19:27 UTC 2015 - dmueller@suse.com

- update to 0.7.3:
  * Fixed regression in new versioning system where upgrade / history
  operation would fail on AttributeError if no version files were
  present at all.
  * Adjusted the SQLite backend regarding autogen of unique constraints
  to work fully with the current SQLAlchemy 1.0, which now will report
  on UNIQUE constraints that have no name.
  * Fixed bug in batch where if the target table contained multiple
  foreign keys to the same target table, the batch mechanics would
  fail with a "table already exists" error.  Thanks for the help
  on this from Lucas Kahlert.
  * Fixed an issue where the MySQL routine to skip foreign-key-implicit
  indexes would also catch unnamed unique indexes, as they would be
  named after the column and look like the FK indexes.  Pull request
  courtesy Johannes Erdfelt.
  * Repaired a regression in both the MSSQL and Oracle dialects whereby
  the overridden ``_exec()`` method failed to return a value, as is
  needed now in the 0.7 series.
  * The ``render_as_batch`` flag was inadvertently hardcoded to ``True``,
  so all autogenerates were spitting out batch mode...this has been
  fixed so that batch mode again is only when selected in env.py.
  * Support for autogenerate of FOREIGN KEY constraints has been added.
  These are delivered within the autogenerate process in the same
  manner as UNIQUE constraints, including ``include_object`` support.
  Big thanks to Ann Kamyshnikova for doing the heavy lifting here.
  * Fixed bug where the "source_schema" argument was not correctly passed
  when calling :meth:`.BatchOperations.create_foreign_key`.  Pull
  request courtesy Malte Marquarding.
  * The "multiple heads / branches" feature has now landed.  This is
  by far the most significant change Alembic has seen since its inception;
  while the workflow of most commands hasn't changed, and the format
  of version files and the ``alembic_version`` table are unchanged as well,
  a new suite of features opens up in the case where multiple version
  files refer to the same parent, or to the "base".  Merging of
  branches, operating across distinct named heads, and multiple
  independent bases are now all supported.   The feature incurs radical
  changes to the internals of versioning and traversal, and should be
  treated as "beta mode" for the next several subsequent releases
  within 0.7.
  * Added "move and copy" workflow, where a table to be altered is copied to
  a new one with the new structure and the old one dropped, is now
  implemented for SQLite as well as all database backends in general
  using the new :meth:`.Operations.batch_alter_table` system.   This
  directive provides a table-specific operations context which gathers
  column- and constraint-level mutations specific to that table, and
  at the end of the context creates a new table combining the structure
  of the old one with the given changes, copies data from old table to new,
  and finally drops the old table,
  renaming the new one to the existing name.  This is required for
  fully featured SQLite migrations, as SQLite has very little support for the
  traditional ALTER directive.   The batch directive
  is intended to produce code that is still compatible with other databases,
  in that the "move and copy" process only occurs for SQLite by default,
  while still providing some level of sanity to SQLite's
  requirement by allowing multiple table mutation operations to
  proceed within one "move and copy" as well as providing explicit
  control over when this operation actually occurs.  The "move and copy"
  feature may be optionally applied to other backends as well, however
  dealing with referential integrity constraints from other tables must
  still be handled explicitly.
  * Relative revision identifiers as used with ``alembic upgrade``,
  ``alembic downgrade`` and ``alembic history`` can be combined with
  specific revisions as well, e.g. ``alembic upgrade ae10+3``, to produce
  a migration target relative to the given exact version.

Mon Sep 15 05:25:46 UTC 2014 - tbechtold@suse.com

- update to version 0.6.7:
  * See
    + http://alembic.readthedocs.org/en/latest/changelog.html#change-0.6.6
    + http://alembic.readthedocs.org/en/latest/changelog.html#change-0.6.7
  * Fixed bug in MSSQL dialect where "rename table" wasn't using
    ``sp_rename()`` as is required on SQL Server.  Pull request courtesy
  * Added support for functional indexes when using the
    :meth:`.Operations.create_index` directive.   Within the list of columns,
    the SQLAlchemy ``text()`` construct can be sent, embedding a literal
    SQL expression; the :meth:`.Operations.create_index` will perform some
    hackery behind the scenes to get the :class:`.Index` construct to cooperate.
    This works around some current limitations in :class:`.Index`
    which should be resolved on the SQLAlchemy side at some point.
  * A file named ``__init__.py`` in the ``versions/`` directory is now
    ignored by Alembic when the collection of version files is retrieved.
    Pull request courtesy Michael Floering.
  * Fixed Py3K bug where an attempt would be made to sort None against
    string values when autogenerate would detect tables across multiple
    schemas, including the default schema.  Pull request courtesy
    paradoxxxzero.
  * Autogenerate render will render the arguments within a Table construct
    using ``*[...]`` when the number of columns/elements is greater than
    255.  Pull request courtesy Ryan P. Kelly.
  * Fixed bug where foreign key constraints would fail to render in
    autogenerate when a schema name was present.  Pull request courtesy
    Andreas Zeidler.
  * Some deep-in-the-weeds fixes to try to get "server default" comparison
    working better across platforms and expressions, in particular on
    the Postgresql backend, mostly dealing with quoting/not quoting of various
    expressions at the appropriate time and on a per-backend basis.
    Repaired and tested support for such defaults as Postgresql interval
    and array defaults.
  * When a run of Alembic command line fails due to ``CommandError``,
    the output now prefixes the string with ``"FAILED:"``, and the error
    is also written to the log output using ``log.error()``.
  * Liberalized even more the check for MySQL indexes that shouldn't be
    counted in autogenerate as "drops"; this time it's been reported
    that an implicitly created index might be named the same as a composite
    foreign key constraint, and not the actual columns, so we now skip those
    when detected as well.
  * Added a new accessor :attr:`.MigrationContext.config`, when used
    in conjunction with a :class:`.EnvironmentContext` and
    :class:`.Config`, this config will be returned.  Patch
    courtesy Marc Abramowitz.

Thu Jul 24 11:33:27 UTC 2014 - dmueller@suse.com

- update to 0.6.5:
  * See http://alembic.readthedocs.org/en/latest/changelog.html#change-0.6.5
  * Added new argument EnvironmentContext.configure.user_module_prefix
  * The ScriptDirectory system that loads migration files from a 
    versions/ directory
  * The command.revision() command now returns the Script object
    corresponding to the newly generated revision
  * Added new feature
    EnvironmentContext.configure.transaction_per_migration, which when True
    causes the BEGIN/COMMIT pair to incur for each migration individually

-------------------------------------------------------------------
Mon Jan 13 13:33:57 UTC 2014 - dmueller@suse.com

- update to 0.6.2:
  * Expanded the size of the “slug” generated by “revision” to 40 characters,
  which is also configurable by new field truncate_slug_length
  * Support for autogeneration detection and rendering of indexes
  and unique constraints has been added
  * Added new argument mssql_drop_foreign_key to Operations.drop_column()
  * Bugfixes

- Require python-setuptools instead of distribute (upstreams merged)

-------------------------------------------------------------------
Thu Aug  8 20:36:51 UTC 2013 - dmueller@suse.com

- update to 0.6.0:
  * [feature] Added new kw argument to EnvironmentContext.configure() include_object.
  * [feature] The output of the alembic history command is now expanded.
  * [feature] Added alembic.config.Config.cmd_opts attribute, allows access to the
  argparse options passed to the alembic runner.(link)
  * [feature] Added new command line argument -x, allows extra arguments to be
  appended to the command line which can be consumed within an env.py script by
  looking at context.config.cmd_opts.x, or more simply a new method
  EnvironmentContext.get_x_argument().(link)
  * [feature] Added -r argument to alembic history command, allows specification of [start]:[end] to view a slice of history. 
  * [feature] Source base is now in-place for Python 2.6 through 3.3, 
  without the need for 2to3. 
  * [feature] Added new kw argument to EnvironmentContext.configure() include_object.

Sun Apr 14 15:53:22 UTC 2013 - p.drouand@gmail.com

- Update to version 0.5.0
  + added version_table_schema argument to EnvironmentContext.configure(),
    complements the version_table argument to set an optional remote schema
    for the version table.
  + added output_encoding option to EnvironmentContext.configure(), used with --sql
    mode to apply an encoding to the output stream.
  + added Operations.create_primary_key() operation, will genenerate an 
    ADD CONSTRAINT for a primary key.
  + upgrade and downgrade commands will list the first line of the docstring
    out next to the version number.
  + added –head-only option to “alembic current”, will print current version
    plus the symbol “(head)” if this version is the head or not.
  + the rendering of any construct during autogenerate can be customized, in particular
    to allow special rendering for user-defined column, constraint subclasses, using new render
   _item argument to EnvironmentContext.configure().
  + fix format of RENAME for table that includes schema with Postgresql; the
    schema name shouldn’t be in the “TO” field.
  + fix bug whereby double quoting would be applied to target column name during an sp_rename operation.
  + fix transactional_ddl flag for SQLite, MySQL dialects set to False. MySQL doesn’t support it,
    SQLite does but current pysqlite driver does not.
  + fix Autogenerate will render additional table keyword arguments like “mysql_engine” and
    others within op.create_table().
  + fix bug whereby create_index() would include in the constraint columns that are added
    to all Table objects using events, externally to the generation of the constraint.
    This is the same issue that was fixed for unique constraints in version 0.3.2.
  + fix worked around a backwards-incompatible regression in Python3.3 regarding argparse;
    running “alembic” with no arguments now yields an informative error in py3.3 as with
    all previous versions.
  + fix host of argument name changes within migration operations for consistency. Keyword
    arguments will continue to work on the old name for backwards compatibility, however required
    positional arguments will not:
    * Operations.alter_column() - name -> new_column_name - old name will work for backwards compatibility.
    * Operations.create_index() - tablename -> table_name - argument is positional.
    * Operations.drop_index() - tablename -> table_name - old name will work for backwards compatibility.
    * Operations.drop_constraint() - tablename -> table_name - argument is positional.
    * Operations.drop_constraint() - type -> type_ - old name will work for backwards compatibility
  + SQLAlchemy 0.6 is no longer supported by Alembic - minimum version is 0.7.3, full support is as of 0.7.9.
- Initial python3 support

Mon Jan 14 16:02:38 UTC 2013 - saschpe@suse.de

- Update to version 0.4.2:
  + Fixed bug where autogenerate would fail if a Column to be added to
    a table made use of the ".key" paramter.
  + Added a workaround to setup.py to prevent "NoneType" error from
    occuring when "setup.py test" is run.
  + Added a README.unittests with instructions for running the test
    suite fully.
- Changes from version 0.4.1:
  + Added support for autogenerate render of ForeignKeyConstraint
    options onupdate, ondelete, initially, and deferred.
  + Explicit error message describing the case when downgrade --sql 
    is used without specifying specific start/end versions.
  + Fixed the minute component in file_template
    which returned the month part of the create date.

Fri Nov 23 10:43:42 UTC 2012 - saschpe@suse.de

- Update to version 0.4.0:
  + [feature] Support for tables in alternate schemas
    has been added fully to all operations, as well as to
    the autogenerate feature.  When using autogenerate,
    specifying the flag include_schemas=True to
    Environment.configure() will also cause autogenerate
    to scan all schemas located by Inspector.get_schema_names(),
    which is supported by *some* (but not all)
    SQLAlchemy dialects including Postgresql.
    *Enormous* thanks to Bruno Binet for a huge effort
    in implementing as well as writing tests.  #33.
  + [feature] The command line runner has been organized
    into a reusable CommandLine object, so that other
    front-ends can re-use the argument parsing built
    in.  #70
  + [feature] Added "stdout" option to Config, provides
    control over where the "print" output of commands like
    "history", "init", "current" etc. are sent.  #43
  + [bug] Fixed the "multidb" template which was badly out
    of date.   It now generates revision files using
    the configuration to determine the different
    upgrade_<xyz>() methods needed as well, instead of
    needing to hardcode these.  Huge thanks to
    BryceLohr for doing the heavy lifting here.  #71
  + [bug] Fixed the regexp that was checking for .py files
    in the version directory to allow any .py file through.
    Previously it was doing some kind of defensive checking,
    probably from some early notions of how this directory
    works, that was prohibiting various filename patterns
    such as those which begin with numbers.  #72
  + [bug] Fixed MySQL rendering for server_default which
    didn't work if the server_default was a generated
    SQL expression.  Courtesy Moriyoshi Koizumi.
  + [feature] Added support for alteration of MySQL
    columns that have AUTO_INCREMENT, as well as enabling
    this flag.  Courtesy Moriyoshi Koizumi.

-------------------------------------------------------------------
Wed Jun  6 12:13:48 UTC 2012 - saschpe@suse.de

- Update to version 0.3.4:
  + [bug] Fixed command-line bug introduced by the
    "revision_environment" feature.
- Changes from version 0.3.3:
  + [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. #44
  + [feature] Added version_table argument to
    EnvironmentContext.configure(), allowing for the
    configuration of the version table name. #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. #49

-------------------------------------------------------------------
Wed May 23 12:55:05 UTC 2012 - saschpe@suse.de

- Update to version 0.3.2:
  + [feature] Basic support for Oracle added
  + [feature] Added support for UniqueConstraint in autogenerate
  + [bug] Fixed support of schema-qualified ForeignKey target in column alter operations,
  + [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.
- Changes from version 0.3.1:
  + [bug] bulk_insert() fixes:
    1. bulk_insert() operation was not working most likely since the 0.2 series
       when used with an engine
    2. 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.
    3. bulk_insert() uses "inline=True" so that phrases like RETURNING and
       such don't get invoked for single-row bulk inserts.
    4. bulk_insert() will check that you're passing a list of dictionaries
       in, raises TypeError if not detected.
- Changes from version 0.3.0:
  + [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.
