Matej Cepl 700d90eb6f - Update to 1.17.2 
* [feature] [operations] Added Operations.implementation_for.replace parameter to
    Operations.implementation_for(), allowing replacement of existing
    operation implementations. This allows for existing operations such as
    CreateTableOp to be extended directly.
  * [bug] [mssql] Fixed issue in SQL Server dialect where the DROP that's automatically
    emitted for existing default constraints during an ALTER COLUMN needs to
    take place before not just the modification of the column's default, but
    also before the column's type is changed.

Fri Apr 4 09:43:05 UTC 2025 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to 1.15.2
* Fixed issue where the "modified_name" of :class:`.AlterColumnOp` would not
be considered when rendering op directives for autogenerate. While
autogenerate cannot detect changes in column name, this would nonetheless
impact approaches that made use of this attribute in rewriter recipes. Pull
request courtesy lenvk.
-------------------------------------------------------------------
Fri Mar 21 10:20:46 UTC 2025 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to 1.15.1
* Fixed an issue in the new :pep:`621` ``pyproject.toml`` layout that
prevented Alembic's template files from being included in the ``.whl``
file in the distribution.
-------------------------------------------------------------------
Mon Jan 27 12:29:40 UTC 2025 - John Paul Adrian Glaubitz <adrian.glaubitz@suse.com>
- Update to 1.14.1
* Modified SQLite’s dialect to render “ALTER TABLE <t> RENAME COLUMN”
when Operations.alter_column() is used with a straight rename,
supporting SQLite’s recently added column rename feature.
* Added tzdata to tz extras, which is required on some platforms
such as Windows. Pull request courtesy Danipulok.
* Fixed bug where autogen render of a “variant” type would fail to
catch the variants if the leading type were a dialect-specific type,
rather than a generic type.
-------------------------------------------------------------------
Tue Nov 19 12:31:07 UTC 2024 - Dirk Müller <dmueller@suse.com>
- update to el_1_14_0:
* **[usecase] [runtime]** Added a new hook to the
`DefaultImpl` `DefaultImpl.version_table_impl()`. This allows
third party dialects to define the exact structure of the
alembic_version table, to include use cases where the table
requires special directives and/or additional columns so that
it may function correctly on a particular backend.
-------------------------------------------------------------------
Sat Sep 28 19:16:36 UTC 2024 - Dirk Müller <dmueller@suse.com>
- update to 1.13.3:
* Render `if_exists` and `if_not_exists` parameters in
`CreateTableOp`, `CreateIndexOp`, `DropTableOp` and
`DropIndexOp` in an autogenerate context.
* Enhance `version_locations` parsing to handle paths containing
newlines.
* Added support for `Operations.create_table.if_not_exists` and
`Operations.drop_table.if_exists`, adding similar
functionality to render IF [NOT] EXISTS for table operations
in a similar way as with indexes.
-------------------------------------------------------------------
Tue Aug 13 23:30:46 UTC 2024 - Guang Yee <gyee@suse.com>
- update to 1.13.2:
* Improve computed column compare function to support multi-line
expressions. Pull request courtesy of Georg Wicke-Arndt.
* Fixed bug in alembic command stdout where long messages were
not properly wrapping at the terminal width. Pull request
courtesy Saif Hakim.
* Fixed internal issue where Alembic would call
connection.execute() sending an empty tuple to indicate
“no params”. In SQLAlchemy 2.1 this case will be deprecated as
“empty sequence” is ambiguous as to its intent.
* Fixes to support pytest 8.1 for the test suite.
* Fixed the detection of serial column in autogenerate with
tables not under default schema on PostgreSQL.
- Drop pytest8.patch as it has merged upstream and included
in the 1.31.2 release.

Wed Dec 27 09:35:46 UTC 2023 - Dirk Müller <dmueller@suse.com>
- update to 1.13.1:
* Fixed :class:`.Rewriter` so that more than two instances
could be chained together correctly, also allowing multiple
``process_revision_directives`` callables to be chained.
* Fixed issue where the method
:meth:`.EnvironmentContext.get_x_argument` using the
:paramref:`.EnvironmentContext.get_x_argument.as_dictionary`
parameter would fail if an argument key were passed on the
command line as a name alone, that is, without an equal sign
``=`` or a value. Behavior is repaired where this condition is
detected and will return a blank string for the given key,
consistent with the behavior where the ``=`` sign is
present and no value.
* Fixed issue where the "unique" flag of an ``Index`` would not
be maintained when generating downgrade migrations.
* Fixed bug in versioning model where a downgrade across a
revision with two down revisions with one down revision
depending on the other, would produce an erroneous state in
the alembic_version table, making upgrades impossible
without manually repairing the table.
* Updated pep-484 typing to pass mypy "strict" mode, however
including per-module qualifications for specific typing
elements not yet complete.
* This allows us to catch specific typing issues that have been
ongoing such as import symbols not properly exported.
-------------------------------------------------------------------
Thu Dec 14 09:13:53 UTC 2023 - Petr Gajdos <pgajdos@suse.com>
- update to 1.13.0:
* Fixed issue where the ``alembic check`` command did not
function correctly with upgrade structures that have multiple,
top-level elements, as are generated from the "multi-env"
environment template.
* Updated logic introduced in :ticket:`151` to allow
``if_exists`` and ``if_not_exists`` on index operations also
on SQLAlchemy 1.4 series. Previously this feature was
mistakenly requiring the 2.0 series.
* Replaced ``python-dateutil`` with the standard library module
zoneinfo.
* Alembic 1.13 now supports Python 3.8 and above.
* Fixed autogenerate issue where ``create_table_comment()`` and
``drop_table_comment()`` rendering in a batch table modify
would include the "table" and "schema" arguments, which are
not accepted in batch as these are already part of the top
level block.
* Additional fixes to PostgreSQL expression index compare
feature. The compare now correctly accommodates casts and
differences in spacing.
* Added detection logic for operation clauses inside the
expression, skipping the compare of these expressions.
* To accommodate these changes the logic for the comparison of
the indexes and unique constraints was moved to the dialect
implementation, allowing greater flexibility.
-------------------------------------------------------------------
Tue Nov 14 12:40:19 UTC 2023 - Dirk Müller <dmueller@suse.com>
- update to 1.12.1:
* Fixed regression caused by :ticket:`879` released in 1.7.0
where the ".info" dictionary of ``Table`` would not render in
autogenerate create table statements.
This can be useful for custom create table DDL rendering
schemes so it is restored.
* Improved typing in the
:paramref:`.EnvironmentContext.configure.process_revision_dir
ectives` callable to better indicate that the passed-in type is
:class:`.MigrationScript`, not the :class:`.MigrationOperation`
base class, and added typing to the example at
:ref:`cookbook_no_empty_migrations` to illustrate.
* Repaired :class:`.ExecuteSQLOp` so that it can participate in
"diff" operations; while this object is typically not present
in a reflected operation stream, custom hooks may be adding
this construct where it needs to have the correct
``to_diff_tuple()`` method.
* Improved the ``op.execute()`` method to correctly accept the
* ``Executable`` type that is the same which is used in
SQLAlchemy ``Connection.execute()``.
* Improve typing of the revision parameter in various command
functions.
* Fixed autogen render issue where expressions inside of
indexes for PG need to be double-parenthesized, meaning a
single parens must be present within the generated ``text()``
construct.
* Alembic now accommodates for Sequence and Identity that
support dialect kwargs.
This is a change that will be added to SQLAlchemy v2.1.

- Clean up the SPEC file
-------------------------------------------------------------------
Mon Sep 25 14:53:14 UTC 2023 - Ondřej Súkup <mimi.vx@gmail.com>
- update to 1.12.0
* Added new feature to the "code formatter" function which allows standalone
executable tools to be run against code, without going through the Python
interpreter. Known as the `exec` runner, it complements the existing
`console_scripts` runner by allowing non-Python tools such as `ruff` to
be used.
* Change the default value of `.EnvironmentContext.configure.compare_type` to `True`.
As Alembic's autogenerate for types was dramatically improved in
version 1.4 released in 2020, the type comparison feature is now much
more reliable so is now enabled by default.
* Fixed issue where the `ForeignKeyConstraint.match` parameter would not be
rendered in autogenerated migrations.
* Fixed issue where the `revision_environment` directive in `alembic.ini`
was ignored by the `alembic merge` command, leading to issues when other
configurational elements depend upon `env.py` being invoked within the
command.
* Added support for `op.drop_constraint()` to support PostgreSQL
`ExcludeConstraint` objects, as well as other constraint-like objects
that may be present in third party dialects, by resolving the `type_`
parameter to be `None` for this case. Autogenerate has also been
enhanced to exclude the `type_` parameter from rendering within this
command when `type_` is `None`.
-------------------------------------------------------------------
Sun Aug 13 19:32:21 UTC 2023 - Dirk Müller <dmueller@suse.com>
- update to 1.11.2:
* Added typing to the default script mako templates.
* Added support in autogenerate for NULLS NOT DISTINCT in
* the PostgreSQL dialect.
* Fixed format string logged when running a post write hook
* Added parameters if_exists and if_not_exists for index
operations.
-------------------------------------------------------------------
Sat Jul 29 21:17:43 UTC 2023 - Dirk Müller <dmueller@suse.com>
- update to 1.11.1:
* As Alembic 1.11.0 is considered a major release (Alembic does
not use semver, nor does its parent project SQLAlchemy;
this has been `clarified <versioning_scheme>` in the documentation),
* :ticket:`1130` modified calling signatures for most
operations to consider all optional keyword parameters to
be keyword-only arguments, to match what was always documented
and generated by autogenerate. However, two of these
changes were identified as possibly problematic without a
more formal deprecation warning being emitted which were the
``table_name`` parameter to :meth:`.Operations.drop_index`,
which was generated positionally by autogenerate prior to
version 0.6.3 released in 2014, and
``type_`` in :meth:`.Operations.drop_constraint` and
:meth:`.BatchOperations.drop_constraint`, which was
documented positionally in one example in the batch documentation.
* Fixed typing use of :class:`~sqlalchemy.schema.Column` and
other generic SQLAlchemy classes.
* Restored the output type of :meth:`.Config.get_section` to
include ``Dict[str, str]`` as a potential return type, which
had been changed to immutable ``Mapping[str, str]``.
When a section is returned and the default is not used,
a mutable dictionary is returned.
* Added placeholder classes for :class:`~.sqla.Computed` and
* :class:`~.sqla.Identity` when older 1.x SQLAlchemy versions
are in use, namely prior to SQLAlchemy 1.3.11 when the
:class:`~.sqla.Computed` construct was introduced.
Previously these were set to None, however this
could cause issues with certain codepaths that were using
``isinstance()`` such as one within "batch mode".
* Correctly pass previously ignored arguments ``insert_before``
and ``insert_after`` in ``batch_alter_column``
* Argument signatures of Alembic operations now enforce
keyword-only arguments as passed as keyword and not
positionally, such as Operations.create_table.schema
.Operations.add_column.type_, etc.
* Fix autogenerate issue with PostgreSQL
:class:`.ExcludeConstraint` that included sqlalchemy
functions. The function text was previously rendered
as a plain string without surrounding with ``text()``.
* Fixed regression caused by :ticket:`1166` released in version
1.10.0 which caused MySQL unique constraints with multiple
columns to not compare correctly within autogenerate,
due to different sorting rules on unique constraints vs.
indexes, which in MySQL are shared constructs.
* Repaired the return signatures for :class:`.Operations` that
mostly return ``None``, and were erroneously referring to
``Optional[Table]`` in many cases.
* Modified the autogenerate implementation for comparing
"server default" values from user-defined metadata to not
apply any quoting to the value before comparing it to the
server-reported default, except for within dialect-specific
routines as needed. This change will affect the format of
the server default as passed to the
:paramref:`.EnvironmentContext.configure.compare_server_defau
lt` hook, as well as for third party dialects that implement
a custom ``compare_server_default`` hook in their alembic
impl, to be passed "as is" and not including additional
quoting. Custom implementations which rely on this quoting
should adjust their approach based on observed formatting.
* allow running async functions in the ``upgrade`` or
``downgrade`` migration function when running alembic using
an async dialect. This function will receive as first argument
an :class:`~sqlalchemy.ext.asyncio.AsyncConnection` sharing the
transaction used in the migration context.

Fri May 5 22:12:29 UTC 2023 - Dirk Müller <dmueller@suse.com>
- update to 1.10.4:
* Added support for autogenerate comparison of indexes on
PostgreSQL which include SQL sort option, such as
``ASC`` or ``NULLS FIRST``.
* Fixed various typing issues observed with pyright, including
issues involving the combination of :class:`.Function` and
:meth:`.MigrationContext.begin_transaction`.
* Fixed error raised by alembic when running autogenerate after
removing a function based index.
* Fixed regression where Alembic would not run with older
SQLAlchemy 1.3 versions prior to 1.3.24 due to a
missing symbol. Workarounds have been applied for older
1.3 versions.
* Fixed issue regarding PostgreSQL :class:`.ExcludeConstraint`,
where constraint elements which made use of :func:`.literal_column`
could not be rendered for autogenerate. Additionally, using SQLAlchemy
2.0.5 or greater, :func:`.text()` constructs are also supported within
PostgreSQL :class:`.ExcludeConstraint` objects for autogenerate render.
* Fixed issue in index detection where autogenerate change
detection would consider indexes with the same columns but with
different order as equal, while in general they are not equivalent
in how a database will use them.
* Recursive traversal of revision files in a particular
revision directory is now supported, by indicating
``recursive_version_locations = true`` in alembic.ini.
* Fixed issue where indexes on SQLite which include SQL
expressions would not compare correctly, generating false
positives under autogenerate. These indexes are now skipped,
generating a warning, in the same way that
expression-based indexes on PostgreSQL are skipped and
generate warnings when SQLAlchemy 1.x installations are
in use. Note that reflection of
SQLite expression-based indexes continues to not yet be
supported under SQLAlchemy 2.0, even though PostgreSQL
expression-based indexes have now been implemented.
* Properly escape constraint name on SQL Server when dropping
a column while specifying ``mssql_drop_default=True`` or
``mssql_drop_check=True`` or ``mssql_drop_foreign_key=True``.
-------------------------------------------------------------------
Fri Feb 10 12:36:15 UTC 2023 - Dirk Müller <dmueller@suse.com>
- update to 1.9.3:
* Fixed issue where rendering of user-defined types
that then went onto use the .with_variant() method would
fail to render, if using SQLAlchemy 2.0's version of variants.
-------------------------------------------------------------------
Sat Jan 28 14:31:09 UTC 2023 - Dirk Müller <dmueller@suse.com>
- update to 1.9.2:
* Fixed typing definitions for :meth:`.EnvironmentContext.get_x_argument`.
Typing stubs are now generated for overloaded proxied methods such as
* Fixed regression caused by :ticket:`1145` where the string transformations
applied to server defaults caused expressions such as ``(getdate())`` to no
longer compare as equivalent on SQL Server, others.
-------------------------------------------------------------------
Thu Jan 5 20:33:31 UTC 2023 - Dirk Müller <dmueller@suse.com>
- update to 1.9.1:
.. change::
:tickets: 1145
Fixed issue where server default compare would not work for string defaults
that contained backslashes, due to mis-rendering of these values when
comparing their contents.
.. change::
:tags: bug, oracle
Implemented basic server default comparison for the Oracle backend;
previously, Oracle's formatting of reflected defaults prevented any
matches from occurring.
.. change::
:tags: bug, sqlite
Adjusted SQLite's compare server default implementation to better handle
defaults with or without parens around them, from both the reflected and
the local metadata side.
.. change::
:tags: bug, mssql
Adjusted SQL Server's compare server default implementation to better
handle defaults with or without parens around them, from both the reflected
and the local metadata side.
-------------------------------------------------------------------
Thu Jan 5 19:06:37 UTC 2023 - Yogalakshmi Arunachalam <yarunachalam@suse.com>
- Update to 1.9.0:
feature
* Added new Alembic command alembic check. This performs the widely requested feature of running an “autogenerate” comparison
between the current database and the MetaData that’s currently set up for autogenerate, returning an error code if the two do not match,
based on current autogenerate settings. Pull request courtesy Nathan Louie.
See also Running Alembic Check to test for new upgrade operations
References: #724
bug
* Fixed issue in tox.ini file where changes in the tox 4.0 series to the format of “passenv” caused tox to not function correctly,
in particular raising an error as of tox 4.0.6.
* Fixed typing issue where revision.process_revision_directives was not fully typed; additionally ensured all Callable and Dict arguments
to EnvironmentContext.configure() include parameters in the typing declaration.
Additionally updated the codebase for Mypy 0.990 compliance.
References: #1110
-------------------------------------------------------------------
Mon Aug 1 21:38:44 UTC 2022 - Dirk Müller <dmueller@suse.com>
- update to 1.8.1:
* Fixed bug where the SQLite implementation of
:meth:`.Operations.rename_table` would render an explicit schema name for
both the old and new table name, which while is the standard ALTER syntax,
is not accepted by SQLite's syntax which doesn't support a rename across
schemas. In particular, the syntax issue would prevent batch mode from
working for SQLite databases that made use of attached databases (which are
treated as "schemas" in SQLAlchemy).
* Added an error raise for the condition where
:meth:`.Operations.batch_alter_table` is used in ``--sql`` mode, where the
operation requires table reflection, as is the case when running against
SQLite without giving it a fixed ``Table`` object. Previously the operation
would fail with an internal error. To get a "move and copy" batch
operation as a SQL script without connecting to a database,
a ``Table`` object should be passed to the
:paramref:`.Operations.batch_alter_table.copy_from` parameter so that
reflection may be skipped.
-------------------------------------------------------------------
Sat Jun 4 20:32:32 UTC 2022 - Arun Persaud <arun@gmx.de>
- update to version 1.8.0:
* changed
+ [changed] [installation] Alembic 1.8 now supports Python 3.7 and
above. References: #1025
+ [changed] [environment] The “Pylons” environment template has
been removed as of Alembic 1.8. This template was based on the
very old pre-Pyramid Pylons web framework which has been long
superseded by Pyramid. References: #987
* feature
+ [feature] [typing] PEP 484 typing annotations have been added to
the env.py and revision template files within migration
templates. Pull request by Nikita Sobolev. References: #764
* usecase
+ [usecase] [operations] The op.drop_table() operation directive
will now trigger the before_drop() and after_drop() DDL event
hooks at the table level, which is similar to how the
before_create() and after_create() hooks are triggered by the
op.create_table() directive. Note that as op.drop_table()
accepts only a table name and optional schema name, the Table
object received by the event will not have any information
within it other than the table name and schema name.
References: #1037
+ [usecase] [commands] Added new token epoch to the file_template
option, which will populate the integer epoch as determined by
int(create_date.timestamp()). Pull request courtesy Caio
Carvalho. References: #1027
* bug
+ [bug] [revisioning] Fixed issue where a downgrade using a
relative revision would fail in case of multiple branches with a
single effectively head due to interdependencies between
revisions. References: #1026
+ [bug] [batch] Fixed issue in batch mode where CREATE INDEX would
not use a new column name in the case of a column rename.

-------------------------------------------------------------------
Sat Mar 26 20:27:41 UTC 2022 - Dirk Müller <dmueller@suse.com>
- update to 1.7.7:
* Fixed issue where using :meth:`.Operations.create_table` in conjunction
with a :class:`.CheckConstraint` that referred to table-bound
:class:`.Column` objects rather than string expressions would be added to
the parent table potentially multiple times, resulting in an incorrect DDL
sequence. Pull request courtesy Nicolas CANIART.
* The ``logging.fileConfig()`` line in ``env.py`` templates, which is used
to setup Python logging for the migration run, is now conditional on
:attr:`.Config.config_file_name` not being ``None``. Otherwise, the line
is skipped as there is no default logging configuration present.
* Fixed bug where an :meth:`.Operations.alter_column` operation would change
a "NOT NULL" column to "NULL" by emitting an ALTER COLUMN statement that
did not specify "NOT NULL". (In the absence of "NOT NULL" T-SQL was
implicitly assuming "NULL"). An :meth:`.Operations.alter_column` operation
that specifies :paramref:`.Operations.alter_column.type` should also
specify include either :paramref:`.Operations.alter_column.nullable` or
:paramref:`.Operations.alter_column.existing_nullable` to inform Alembic as
to whether the emitted DDL should include "NULL" or "NOT NULL"; a warning
is now emitted if this is missing under this scenario.
-------------------------------------------------------------------
Mon Feb 14 21:37:49 UTC 2022 - Dirk Müller <dmueller@suse.com>
- update to 1.7.6:
* Add a new command alembic ensure_version, which will ensure that the Alembic
version table is present in the target database, but does not alter its
contents.
* Fixed regression where usage of a with_variant() datatype in conjunction with
the existing_type option of op.alter_column() under batch mode would lead to an
internal exception.
* Implemented support for recognizing and rendering SQLAlchemy “variant” types
going forward into SQLAlchemy 2.0, where the architecture of “variant”
datatypes will be changing.
* Added a rule to the MySQL impl so that the translation between JSON / LONGTEXT
is accommodated by autogenerate, treating LONGTEXT from the server as
equivalent to an existing JSON in the model.
* Removed a warning raised by SQLAlchemy when dropping constraints on MSSQL
regarding statement caching.
-------------------------------------------------------------------
Mon Dec 6 17:51:23 UTC 2021 - Dirk Müller <dmueller@suse.com>

-------------------------------------------------------------------
Sun Oct 17 22:28:50 UTC 2021 - Dirk Müller <dmueller@suse.com>
- update to 1.7.4:
* Fixed a regression that prevented the use of post write hooks on python
version lower than 3.9
* Added missing attributes from context stubs.
* Fixed issue where registration of custom ops was prone to failure due to
the registration process running exec() on generated code that as of the
1.7 series includes pep-484 annotations, which in the case of end user code
would result in name resolution errors when the exec occurs
-------------------------------------------------------------------
Sun Sep 5 16:08:27 UTC 2021 - Arun Persaud <arun@gmx.de>
- specfile:
* skip python 2 builds
* require importlib-resources
- update to version 1.7.1:
* Corrected "universal wheel" directive in setup.cfg so that
building a wheel does not target Python 2. The PyPi files index
for 1.7.0 was corrected manually. Pull request courtesy layday.
* Fixed issue in generated .pyi files where default values for
"Optional" arguments were missing, thereby causing mypy to
consider them as required.
* Fixed regression in batch mode due to :ticket:`883` where the
"auto" mode of batch would fail to accommodate any additional
migration directives beyond encountering an "add_column()"
directive, due to a mis-application of the conditional logic that
was added as part of this change, leading to "recreate" mode not
being used in cases where it is required for SQLite such as for
unique constraints.
- changes from version 1.7.0:
* Fixed regression due to :ticket:`803` where the ".info" and
".comment" attributes of "Table" would be lost inside of the
:class:`.DropTableOp` class, which when "reversed" into a
:class:`.CreateTableOp` would then have lost these elements. Pull
request courtesy Nicolas CANIART.
* Enhance "version_locations" parsing to handle paths containing
spaces. The new configuration option "version_path_separator"
specifies the character to use when splitting the
"version_locations" string. The default for new configurations is
"version_path_separator = os", which will use "os.pathsep" (e.g.,
";" on Windows).
* Alembic 1.7 now supports Python 3.6 and above; support for prior
versions including Python 2.7 has been dropped.
* Batch "auto" mode will now select for "recreate" if the
"add_column()" operation is used on SQLite, and the column itself
meets the criteria for SQLite where ADD COLUMN is not allowed, in
this case a functional or parenthesized SQL expression or a
"Computed" (i.e. generated) column.
* Make the "python-dateutil" library an optional dependency. This
library is only required if the "timezone" option is used in the
Alembic configuration. An extra require named "tz" is available
with "pip install alembic[tz]" to install it.
* Re-implemented the "python-editor" dependency as a small internal
function to avoid the need for external dependencies.
* Named CHECK constraints are now supported by batch mode, and will
automatically be part of the recreated table assuming they are
named. They also can be explicitly dropped using
"op.drop_constraint()". For "unnamed" CHECK constraints, these are
still skipped as they cannot be distinguished from the CHECK
constraints that are generated by the "Boolean" and "Enum"
datatypes. Note that this change may require adjustments to
migrations that drop or rename columns which feature an associated
named check constraint, such that an additional
"op.drop_constraint()" directive should be added for that named
constraint as there will no longer be an associated column for it;
for the "Boolean" and "Enum" datatypes, an "existing_type" keyword
may be passed to "BatchOperations.drop_constraint" as well.
* The dependency on "pkg_resources" which is part of "setuptools"
has been removed, so there is no longer any runtime dependency on
"setuptools". The functionality has been replaced with
"importlib.metadata" and "importlib.resources" which are both part
of Python std.lib, or via pypy dependency "importlib-metadata" for
Python version < 3.8 and "importlib-resources" for Python version
< 3.9 (while importlib.resources was added to Python in 3.7, it
did not include the "files" API until 3.9).
* Created a "test suite" similar to the one for SQLAlchemy, allowing
developers of third-party dialects to test their code against a
set of Alembic tests that have been specially selected to exercise
back-end database operations. At the time of release, third-party
dialects that have adopted the Alembic test suite to verify
compatibility include `CockroachDB
<https://pypi.org/project/sqlalchemy-cockroachdb/>`_ and `SAP ASE
(Sybase) <https://pypi.org/project/sqlalchemy-sybase/>`_.
* Fixed issue where usage of the PostgreSQL "postgresql_include"
option within a :meth:`.Operations.create_index` would raise a
KeyError, as the additional column(s) need to be added to the
table object used by the construct internally. The issue is
equivalent to the SQL Server issue fixed in :ticket:`513`. Pull
request courtesy Steven Bronson.
* pep-484 type annotations have been added throughout the library.
Additionally, stub .pyi files have been added for the
"dynamically" generated Alembic modules "alembic.op" and
"alembic.config", which include complete function signatures and
docstrings, so that the functions in these namespaces will have
both IDE support (vscode, pycharm, etc) as well as support for
typing tools like Mypy. The files themselves are statically
generated from their source functions within the source tree.

- update to version 1.6.2:
* bug
+ [bug] [regression] [versioning] Fixed additional regression
nearly the same as that of #838 just released in 1.6.1 but
within a slightly different codepath, where “alembic downgrade
head” (or equivalent) would fail instead of iterating no
revisions.
- changes from version 1.6.1:
* bug
+ [bug] [regression] [versioning] Fixed regression in new
revisioning traversal where “alembic downgrade base” would fail
if the database itself were clean and unversioned; additionally
repairs the case where downgrade would fail if attempting to
downgrade to the current head that is already present.
- changes from version 1.6.0:
* feature
+ [feature] [autogenerate] Fix the documentation regarding the
default command-line argument position of the revision script
filename within the post-write hook arguments. Implement a
REVISION_SCRIPT_FILENAME token, enabling the position to be
changed. Switch from str.split() to shlex.split() for more
robust command-line argument parsing.
+ [feature] Implement a .cwd (current working directory) suboption
for post-write hooks (of type console_scripts). This is useful

* bug
+ [bug] [autogenerate] Refactored the implementation of
MigrateOperation constructs such as CreateIndexOp,
CreateTableOp, etc. so that they no longer rely upon maintaining
a persistent version of each schema object internally; instead,
the state variables of each operation object will be used to
produce the corresponding construct when the operation is
invoked. The rationale is so that environments which make use of
operation-manipulation schemes such as those those discussed in
Fine-Grained Autogenerate Generation with Rewriters are better
supported, allowing end-user code to manipulate the public
attributes of these objects which will then be expressed in the
final output, an example is
some_create_index_op.kw["postgresql_concurrently"] = True.
Previously, these objects when generated from autogenerate would
typically hold onto the original, reflected element internally
without honoring the other state variables of each construct,
preventing the public API from working.
+ [bug] [environment] Fixed regression caused by the SQLAlchemy
1.4/2.0 compatibility switch where calling .rollback() or
.commit() explicitly within the context.begin_transaction()
context manager would cause it to fail when the block ended, as
it did not expect that the transaction was manually closed.
+ [bug] [autogenerate] Improved the rendering of op.add_column()
operations when adding multiple columns to an existing table, so
that the order of these statements matches the order in which
the columns were declared in the application’s table
metadata. Previously the added columns were being sorted
alphabetically.
+ [bug] [versioning] The algorithm used for calculating
downgrades/upgrades/iterating revisions has been rewritten, to
resolve ongoing issues of branches not being handled
consistently particularly within downgrade operations, as well
as for overall clarity and maintainability. This change includes
that a deprecation warning is emitted if an ambiguous command
such as “downgrade -1” when multiple heads are present is given.
In particular, the change implements a long-requested use case
of allowing downgrades of a single branch to a branchpoint.
Huge thanks to Simon Bowly for their impressive efforts in
successfully tackling this very difficult problem.
+ [bug] [batch] Added missing batch_op.create_table_comment(),
batch_op.drop_table_comment() directives to batch ops.

Wed Apr 7 05:16:16 UTC 2021 - Steve Kowalik <steven.kowalik@suse.com>
- Update to 1.5.8:
* Fixed regression caused by SQLAlchemy 1.4 where the "alembic current"
command would fail due to changes in the ``URL`` object.
* Add async template to Alembic to bootstrap environments that use
async DBAPI. Updated the cookbook to include a migration guide
on how to adapt an existing enviroment for use with DBAPI drivers.
* Fixed bug in versioning model where a downgrade across a revision with a
dependency on another branch, yet an ancestor is also dependent on that
branch, would produce an erroneous state in the alembic_version table,
making upgrades impossible without manually repairing the table.
* Changed the default ordering of "CREATE" and "DROP" statements indexes and
unique constraints within the autogenerate process, so that for example in
an upgrade() operation, a particular index or constraint that is to be
replaced such as for a casing convention change will not produce any naming
conflicts.
* Fixed issue where autogenerate rendering of ``op.alter_column()`` would
fail to include MySQL ``existing_nullable=False`` if the column were part
of a primary key constraint within the table metadata.
* Added support for rendering of "identity" elements on
:class:`.Column` objects, supported in SQLAlchemy via
the :class:`.Identity` element introduced in version 1.4.
* Adding columns with identity is supported on PostgreSQL,
MSSQL and Oracle. Changing the identity options or removing
it is supported only on PostgreSQL and Oracle.
* To accommodate SQLAlchemy 1.4 and 2.0, the migration model now no longer
assumes that the SQLAlchemy Connection will autocommit an individual
operation.
* Modified the ``add_column()`` operation such that the ``Column`` object in
use is shallow copied to a new instance if that ``Column`` is already
attached to a ``table()`` or ``Table``.
* Added rendering for the ``Table.prefixes`` element to autogenerate so that
the rendered Python code includes these directives.
* Alembic 1.5.0 now supports **Python 2.7 and Python 3.6 and above**, as well
as **SQLAlchemy 1.3.0 and above**.
* Add ``__main__.py`` file to alembic package to support invocation
with ``python -m alembic``.
* Removed deprecated ``--head_only`` option to the ``alembic current``

- update to version 1.4.3:
* bug
+ Added support to drop named CHECK constraints that are specified
as part of a column, rather than table wide. Previously, only
constraints associated with the table were considered.
References: #711
+ Fixed issue where the MySQL dialect would not correctly render
the server default of a column in an alter operation, if the
operation were programmatically generated from an autogenerate
pass as it would not accommodate for the full structure of the
DefaultClause construct. References: #736
+ Fixed issue where the CAST applied to a JSON column when copying
a SQLite table during batch mode would cause the data to be
lost, as SQLite’s CAST with JSON appears to convert the data to
the value “0”. The CAST is now skipped in a dialect-specific
manner, including for JSON columns on SQLite. Pull request
courtesy Sebastián Ramírez. References: #697
+ The alembic current command no longer creates an alembic_version
table in the database if one does not exist already, returning
no version as the current version. This allows checking for
migrations in parallel without introducing race conditions. Pull
request courtesy Nikolay Edigaryev. References: #694
+ Fixed issue where columns in a foreign-key referenced table
would be replaced with null-type columns during a batch
operation; while this did not generally have any side effects,
it could theoretically impact a batch operation that also
targets that table directly and also would interfere with future
changes to the .append_column() method to disallow implicit
replacement of columns.
+ Fixed issue where the mssql_drop_foreign_key=True flag on
op.drop_column would lead to incorrect syntax error due to a
typo in the SQL emitted, same typo was present in the test as
well so it was not detected. Pull request courtesy Oleg
Shigorin. References: #716

the recently released py.test 5.4.0. References: #668
+ Fixed more false-positive failures produced by the new “compare
type” logic first added in #605, particularly impacting MySQL
string types regarding flags such as “charset” and “collation”.
References: #671
+ Fixed issue in Oracle backend where a table RENAME with a
schema-qualified name would include the schema in the “to”
portion, which is rejected by Oracle. References: #670
* usecase
+ Adjusted autogen comparison to accommodate for backends that
support computed column reflection, dependent on SQLAlchemy
version 1.3.16 or higher. This emits a warning if the SQL
expression inside of a Computed value changes between the
metadata and the database, as these expressions can’t be changed
without dropping and recreating the column. References: #669

Fri Mar 6 21:49:43 UTC 2020 - Arun Persaud <arun@gmx.de>
- update to version 1.4.1:
* Fixed regression caused by the new “type comparison” logic
introduced in 1.4 as part of #605 where comparisons of MySQL
“unsigned integer” datatypes would produce false positives, as the
regular expression logic was not correctly parsing the “unsigned”
token when MySQL’s default display width would be returned by the
database. Pull request courtesy Paul Becotte. References: #661
* Error message for “path doesn’t exist” when loading up script
environment now displays the absolute path. Pull request courtesy
Rowan Hart. References: #663
* Fixed regression in 1.4.0 due to #647 where unique constraint
comparison with mixed case constraint names while not using a
naming convention would produce false positives during
autogenerate.References: #654
* The check for matched rowcount when the alembic_version table is
updated or deleted from is now conditional based on whether or not
the dialect supports the concept of “rowcount” for UPDATE or
DELETE rows matched. Some third party dialects do not support this
concept. Pull request courtesy Ke Zhu.
* Fixed long-standing bug where an inline column CHECK constraint
would not be rendered within an “ADD COLUMN” operation. The DDL
compiler is now consulted for inline constraints within the
Operations.add_column() method as is done for regular CREATE TABLE
operations. References: #655
-------------------------------------------------------------------
Sat Feb 8 20:39:12 UTC 2020 - Arun Persaud <arun@gmx.de>
- update to version 1.4.0:
* feature
+ Added new parameters BatchOperations.add_column.insert_before,
BatchOperations.add_column.insert_after which provide for
establishing the specific position in which a new column should
be placed. Also added
Operations.batch_alter_table.partial_reordering which allows the
complete set of columns to be reordered when the new table is
created. Both operations apply only to when batch mode is
recreating the whole table using recreate="always". Thanks to
Marcin Szymanski for assistance with the implementation.
References: #640
* bug
+ Adjusted the unique constraint comparison logic in a similar
manner as that of #421 did for indexes in order to take into
account SQLAlchemy’s own truncation of long constraint names
when a naming convention is in use. Without this step, a name
that is truncated by SQLAlchemy based on a unique constraint
naming convention or hardcoded name will not compare properly.
References: #647
+ A major rework of the “type comparison” logic is in place which
changes the entire approach by which column datatypes are
compared. Types are now compared based on the DDL string
generated by the metadata type vs. the datatype reflected from
the database. This means we compare types based on what would
actually render and additionally if elements of the types change
like string length, those changes are detected as well. False
positives like those generated between SQLAlchemy Boolean and
MySQL TINYINT should also be resolved. Thanks very much to Paul
Becotte for lots of hard work and patience on this one. See
also: What does Autogenerate Detect (and what does it not
detect?) - updated comments on type comparison References: #605
* usecase
+ Moved the use of the __file__ attribute at the base of the
Alembic package into the one place that it is specifically
needed, which is when the config attempts to locate the template
directory. This helps to allow Alembic to be fully importable in
environments that are using Python memory-only import
schemes. Pull request courtesy layday. References: #648
* misc
+ The internal inspection routines no longer use SQLAlchemy’s
Inspector.from_engine() method, which is expected to be
deprecated in 1.4. The inspect() function is now used.

+ Fixed issue where COMMENT directives for PostgreSQL failed to
correctly include an explicit schema name, as well as correct
quoting rules for schema, table, and column names. Pull request
courtesy Matthew Sills. References: #637
* usecase
+ Added support for rendering of “computed” elements on Column
objects, supported in SQLAlchemy via the new Computed element
introduced in version 1.3.11. Pull request courtesy Federico
Caselli.
Note that there is currently no support for ALTER COLUMN to add,
remove, or modify the “GENERATED ALWAYS AS” element from a
column; at least for PostgreSQL, it does not seem to be
supported by the database. Additionally, SQLAlchemy does not
currently reliably reflect the “GENERATED ALWAYS AS” phrase from
an existing column, so there is also no autogenerate support for
addition or removal of the Computed element to or from an
existing column, there is only support for adding new columns
that include the Computed element. In the case that the Computed
element is removed from the Column object in the table metadata,
PostgreSQL and Oracle currently reflect the “GENERATED ALWAYS
AS” expression as the “server default” which will produce an op
that tries to drop the element as a default. References: #624

- update to 1.2.1:
* bugs
+ Reverted the name change of the “revisions” argument to
command.stamp() to “revision” as apparently applications are
calling upon this argument as a keyword name. Pull request
courtesy Thomas Bechtold. Special translations are also added
to the command line interface so that it is still known
as “revisions” in the CLI.
References: #601
+ Removed the “test requirements” from “setup.py test”, as
this command now only emits a removal error in any case
and these requirements are unused.
-------------------------------------------------------------------
Sat Sep 21 19:10:16 UTC 2019 - Arun Persaud <arun@gmx.de>
- update to version 1.2.0:
* feature
+ Added new --purge flag to the alembic stamp command, which will
unconditionally erase the version table before stamping
anything. This is useful for development where non-existent
version identifiers might be left within the table. Additionally,
alembic.stamp now supports a list of revision identifiers, which
are intended to allow setting up muliple heads at once. Overall
handling of version identifiers within the alembic.stamp command
has been improved with many new tests and use cases added.
References: #473
+ Added new feature MigrationContext.autocommit_block(), a special
directive which will provide for a non-transactional block inside
of a migration script. The feature requres that: the database
driver (e.g. DBAPI) supports the AUTOCOMMIT isolation mode. The
directive also necessarily needs to COMMIT the existing
transaction in progress in order to enter autocommit mode. See
also MigrationContext.autocommit_block() References: #123
+ Added “post write hooks” to revision generation. These allow
custom logic to run after a revision Python script is generated,
typically for the purpose of running code formatters such as
“Black” or “autopep8”, but may be used for any arbitrary
post-render hook as well, including custom Python functions or
scripts. The hooks are enabled by providing a [post_write_hooks]
section in the alembic.ini file. A single hook is provided which
runs an arbitrary Python executable on the newly generated
revision script, which can be configured to run code formatters
such as Black; full examples are included in the documentation.
See also Applying Post Processing and Python Code Formatters to
Generated Revisions References: #307
+ Added new flag --package to alembic init. For environments where
the Alembic migration files and such are within the package tree
and importable as modules, this flag can be specified which will
add the additional __init__.py files in the version location and
the environment location. References: #463
* bug
+ Improved the Python rendering of a series of migration
operations such that a single “pass” is rendered for a
UpgradeOps or DowngradeOps based on if no lines of Python code
actually rendered under the operation, rather than whether or
not sub-directives exist. Removed extra “pass” lines that would
generate from the ModifyTableOps directive so that these aren’t
duplicated under operation rewriting scenarios. References:
#550
+ Fixed bug where rendering of comment text for table-level
comments within Operations.create_table_comment() and
Operations.drop_table_comment() was not properly quote-escaped
within rendered Python code for autogenerate. References: #549
+ Modified the logic of the Rewriter object such that it keeps a
memoization of which directives it has processed, so that it can
ensure it processes a particular directive only once, and
additionally fixed Rewriter so that it functions correctly for
multiple-pass autogenerate schemes, such as the one illustrated
in the “multidb” template. By tracking which directives have
been processed, a multiple-pass scheme which calls upon the
Rewriter multiple times for the same structure as elements are
added can work without running duplicate operations on the same
elements more than once. References: #505
* usecase
+ Added autogenerate support for Column objects that have
dialect-specific **kwargs, support first added in SQLAlchemy
1.3. This includes SQLite “on conflict” as well as options used
by some third party dialects. References: #518
+ Added rendering for SQLAlchemy Variant datatypes, which render
as the base type plus one or more .with_variant() method calls.
References: #131
+ Made the command interface revision lookup behavior more strict
in that an Alembic revision number is only resolved based on a
partial match rules if it has at least four characters, to
prevent simple typographical issues from inadvertently running
migrations. References: #534
* misc
+ Python 3.4 support is dropped, as the upstream tooling (pip,
mysqlclient) etc are already dropping support for Python 3.4,
which itself is no longer maintained.

- specfile:
* increased min version of SQLAlechmy
- update to version 1.1.0:
* bug
+ Fixed bug where the double-percent logic applied to some
dialects such as psycopg2 would be rendered in --sql mode, by
allowing dialect options to be passed through to the dialect
used to generate SQL and then providing paramstyle="named" so
that percent signs need not be doubled. For users having this
issue, existing env.py scripts need to add
dialect_opts={"paramstyle": "named"} to their offline
context.configure(). See the alembic/templates/generic/env.py
template for an example. References: #562
+ Fixed use of the deprecated “imp” module, which is used to
detect pep3147 availability as well as to locate .pyc files,
which started emitting deprecation warnings during the test
suite. The warnings were not being emitted earlier during the
test suite, the change is possibly due to changes in py.test
itself but this is not clear. The check for pep3147 is set to
True for any Python version 3.5 or greater now and importlib is
used when available. Note that some dependencies such as
distutils may still be emitting this warning. Tests are adjusted
to accommodate for dependencies that emit the warning as well.
+ Fixed issue where emitting a change of column name for MySQL did
not preserve the column comment, even if it were specified as
existing_comment. References: #594
+ Removed the “python setup.py test” feature in favor of a
straight run of “tox”. Per Pypa / pytest developers, “setup.py”
commands are in general headed towards deprecation in favor of
tox. The tox.ini script has been updated such that running “tox”
with no arguments will perform a single run of the test suite
against the default installed Python interpreter. See also

https://github.com/pytest-dev/pytest/issues/5534
References: #592
* usecase
+ The “alembic init” command will now proceed if the target
directory exists as long as it’s still empty. Previously, it
would not proceed if the directory existed. The new behavior is
modeled from what git does, to accommodate for container or
other deployments where an Alembic target directory may need to
be already mounted instead of being created with alembic
init. Pull request courtesy Aviskar KC. References: #571
* misc
+ Alembic 1.1 bumps the minimum version of SQLAlchemy to 1.1. As
was the case before, Python requirements remain at Python 2.7,
or in the 3.x series Python 3.4.
+ The test suite for Alembic now makes use of SQLAlchemy’s testing
framework directly. Previously, Alembic had its own version of
this framework that was mostly copied from that of SQLAlchemy to
enable testing with older SQLAlchemy versions. The majority of
this code is now removed so that both projects can leverage
improvements from a common testing framework.
-------------------------------------------------------------------
Sat Jul 6 21:27:43 UTC 2019 - Arun Persaud <arun@gmx.de>
- update to version 1.0.11:
* bug
+ SQLite server default reflection will ensure parenthesis are
surrounding a column default expression that is detected as
being a non-constant expression, such as a datetime() default,
to accommodate for the requirement that SQL expressions have to
be parenthesized when being sent as DDL. Parenthesis are not
added to constant expressions to allow for maximum
cross-compatibility with other dialects and existing test suites
(such as Alembic’s), which necessarily entails scanning the
expression to eliminate for constant numeric and string
values. The logic is added to the two “reflection->DDL round
trip” paths which are currently autogenerate and batch
migration. Within autogenerate, the logic is on the rendering
side, whereas in batch the logic is installed as a column
reflection hook. References: #579
+ Improved SQLite server default comparison to accommodate for a
text() construct that added parenthesis directly vs. a construct
that relied upon the SQLAlchemy SQLite dialect to render the
parenthesis, as well as improved support for various forms of
constant expressions such as values that are quoted
vs. non-quoted. References: #579
+ Fixed bug where the “literal_binds” flag was not being set when
autogenerate would create a server default value, meaning server
default comparisons would fail for functions that contained
literal values.
+ Added support for MySQL “DROP CHECK”, which is added as of MySQL
8.0.16, separate from MariaDB’s “DROP CONSTRAINT” for CHECK
constraints. The MySQL Alembic implementation now checks for
“MariaDB” in server_version_info to decide which one to use.
References: #554
+ Fixed issue where MySQL databases need to use CHANGE COLUMN when
altering a server default of CURRENT_TIMESTAMP, NOW() and
probably other functions that are only usable with
DATETIME/TIMESTAMP columns. While MariaDB supports both CHANGE
and ALTER COLUMN in this case, MySQL databases only support
CHANGE. So the new logic is that if the server default change is
against a DateTime-oriented column, the CHANGE format is used
unconditionally, as in the vast majority of cases the server
default is to be CURRENT_TIMESTAMP which may also be potentially
bundled with an “ON UPDATE CURRENT_TIMESTAMP” directive, which
SQLAlchemy does not currently support as a distinct field. The
fix addiionally improves the server default comparison logic
when the “ON UPDATE” clause is present and there are parenthesis
to be adjusted for as is the case on some MariaDB versions.
References: #564
+ Warnings emitted by Alembic now include a default stack level of
2, and in some cases it’s set to 3, in order to help warnings
indicate more closely where they are originating from. Pull
request courtesy Ash Berlin-Taylor.
+ Replaced the Python compatbility routines for getargspec() with
a fully vendored version based on getfullargspec() from Python
3.3. Originally, Python was emitting deprecation warnings for
this function in Python 3.8 alphas. While this change was
reverted, it was observed that Python 3 implementations for
getfullargspec() are an order of magnitude slower as of the 3.4
series where it was rewritten against Signature. While Python
plans to improve upon this situation, SQLAlchemy projects for
now are using a simple replacement to avoid any future issues.

- update to version 1.0.9:
* Simplified the internal scheme used to generate the alembic.op
namespace to no longer attempt to generate full method signatures
(e.g. rather than generic *args, **kw) as this was not working in
most cases anyway, while in rare circumstances it would in fact
sporadically have access to the real argument names and then fail
when generating the function due to missing symbols in the
argument signature.

- update to version 0.9.8:
* [bug] [runtime] Fixed bug where the Script.as_revision_number()
method did not accommodate for the ‘heads’ identifier, which in
turn caused the EnvironmentContext.get_head_revisions() and
EnvironmentContext.get_revision_argument() methods to be not
usable when multiple heads were present. The
:meth:.`EnvironmentContext.get_head_revisions` method returns a
tuple in all cases as documented. References: #482
* [bug] [autogenerate] [postgresql] Fixed bug where autogenerate of
ExcludeConstraint would render a raw quoted name for a Column that
has case-sensitive characters, which when invoked as an inline
member of the Table would produce a stack trace that the quoted
name is not found. An incoming Column object is now rendered as
sa.column('name'). References: #478
* [bug] [autogenerate] Fixed bug where the indexes would not be
included in a migration that was dropping the owning table. The
fix now will also emit DROP INDEX for the indexes ahead of time,
but more importantly will include CREATE INDEX in the downgrade
migration. References: #468
* [bug] [postgresql] Fixed the autogenerate of the module prefix
when rendering the text_type parameter of postgresql.HSTORE, in
much the same way that we do for ARRAY’s type and JSON’s
text_type. References: #480
* [bug] [mysql] Added support for DROP CONSTRAINT to the MySQL
Alembic dialect to support MariaDB 10.2 which now has real CHECK
constraints. Note this change does not add autogenerate support,

added for indexes that have case-sensitive names. Works with
SQLAlchemy 0.9 and later series.
* [bug] [autogenerate] [postgresql] Fixed bug where autogenerate
would produce a DROP statement for the index implicitly created by
a Postgresql EXCLUDE constraint, rather than skipping it as is the

ARRAY type, the fix now accommodates for the generic
sqlalchemy.types.ARRAY type added in SQLAlchemy 1.1, rendering the
inner type correctly regardless of whether or not the Postgresql
dialect is present. References: #442

CURRENT_TIMESTAMP would fail on MariaDB 10.2 due to a change in
how the function is represented by the database during reflection.

* [bug] [autogenerate] Fixed bug where comparison of Numeric types
would produce a difference if the Python-side Numeric
inadvertently specified a non-None “scale” with a “precision” of
None, even though this Numeric type will pass over the “scale”
argument when rendering. Pull request courtesy Ivan Mmelnychuk.
References: pull request bitbucket:70
* [bug] [batch] The name of the temporary table in batch mode is now
generated off of the original table name itself, to avoid
conflicts for the unusual case of multiple batch operations
running against the same database schema at the same time.
References: #457
* [bug] [autogenerate] A ForeignKeyConstraint can now render
correctly if the link_to_name flag is set, as it will not attempt
to resolve the name from a “key” in this case. Additionally, the
constraint will render as-is even if the remote column name isn’t
present on the referenced remote table. References: #456
* [bug] [runtime] [py3k] Reworked “sourceless” system to be fully
capable of handling any combination of: Python2/3x, pep3149 or
not, PYTHONOPTIMIZE or not, for locating and loading both env.py

inside of __pycache__ as well as listing out version files that
might be only in versions/__pycache__, deduplicating version files
that may be in versions/__pycache__ and versions/ at the same
time, correctly looking for .pyc or .pyo files based on if pep488
is present or not. The latest Python3x deprecation warnings
involving importlib are also corrected.

-------------------------------------------------------------------
Mon Aug 15 10:24:57 UTC 2016 - tbechtold@suse.com
- update to 0.8.7:
- Fixed bug where upgrading to the head of a branch which is already
present would fail, only if that head were also the dependency
of a different branch that is also upgraded, as the revision system
would see this as trying to go in the wrong direction. The check
here has been refined to distinguish between same-branch revisions
out of order vs. movement along sibling branches.
- Adjusted the version traversal on downgrade
such that we can downgrade to a version that is a dependency for
a version in a different branch, *without* needing to remove that
dependent version as well. Previously, the target version would be
seen as a "merge point" for it's normal up-revision as well as the
dependency. This integrates with the changes for :ticket:`377`
and :ticket:`378` to improve treatment of branches with dependencies
overall.
- Fixed bug where a downgrade to a version that is also a dependency
to a different branch would fail, as the system attempted to treat
this as an "unmerge" of a merge point, when in fact it doesn't have
the other side of the merge point available for update.
- Fixed bug where the "alembic current" command wouldn't show a revision
as a current head if it were also a dependency of a version in a
different branch that's also applied. Extra logic is added to
extract "implied" versions of different branches from the top-level
versions listed in the alembic_version table.
- Fixed bug where a repr() or str() of a Script object would fail
if the script had multiple dependencies.
- Fixed bug in autogen where if the DB connection sends the default
schema as "None", this "None" would be removed from the list of
schemas to check if include_schemas were set. This could possibly
impact using include_schemas with SQLite.
- Small adjustment made to the batch handling for reflected CHECK
constraints to accommodate for SQLAlchemy 1.1 now reflecting these.
Batch mode still does not support CHECK constraints from the reflected
table as these can't be easily differentiated from the ones created
by types such as Boolean.

Fri Jun 3 16:37:33 UTC 2016 - tbechtold@suse.com
- update to 0.8.6:
- Errors which occur within the Mako render step are now intercepted
and raised as CommandErrors like other failure cases; the Mako
exception itself is written using template-line formatting to
a temporary file which is named in the exception message.
- Added a fix to Postgresql server default comparison which first checks
if the text of the default is identical to the original, before attempting
to actually run the default. This accomodates for default-generation
functions that generate a new value each time such as a uuid function.
- Fixed bug introduced by the fix for :ticket:`338` in version 0.8.4
where a server default could no longer be dropped in batch mode.
Pull request courtesy Martin Domke.
- Fixed bug where SQL Server arguments for drop_column() would not
be propagated when running under a batch block. Pull request
courtesy Michal Petrucha.
-------------------------------------------------------------------
Thu Apr 7 06:24:53 UTC 2016 - tbechtold@suse.com
- update to 0.8.5:
- Fixed bug where the columns rendered in a ``PrimaryKeyConstraint``
in autogenerate would inappropriately render the "key" of the
column, not the name. Pull request courtesy Jesse Dhillon.
- Repaired batch migration support for "schema" types which generate
constraints, in particular the ``Boolean`` datatype which generates
a CHECK constraint. Previously, an alter column operation with this
type would fail to correctly accommodate for the CHECK constraint
on change both from and to this type. In the former case the operation
would fail entirely, in the latter, the CHECK constraint would
not get generated. Both of these issues are repaired.
- Changing a schema type such as ``Boolean`` to a non-schema type would
emit a drop constraint operation which emits ``NotImplementedError`` for
the MySQL dialect. This drop constraint operation is now skipped when
the constraint originates from a schema type.
- 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.
- Added an autogenerate renderer for the :class:`.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 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.
- Added a type-level comparator that distinguishes :class:`.Integer`,
:class:`.BigInteger`, and :class:`.SmallInteger` types and
dialect-specific types; these all have "Integer" affinity so previously
all compared as the same.
- Fixed bug where the ``server_default`` parameter of ``alter_column()``
would not function correctly in batch mode.
- Adjusted the rendering for index expressions such that a :class:`.Column`
object present in the source :class:`.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.
- Fixed an 0.8 regression whereby the "imports" dictionary member of
the autogen context was removed; this collection is documented in the
"render custom type" documentation as a place to add new imports.
The member is now known as
:attr:`.AutogenContext.imports` and the documentation is repaired.
- Fixed bug in batch mode where a table that had pre-existing indexes
would create the same index on the new table with the same name,
which on SQLite produces a naming conflict as index names are in a
global namespace on that backend. Batch mode now defers the production
of both existing and new indexes until after the entire table transfer
operation is complete, which also means those indexes no longer take
effect during the INSERT from SELECT section as well; the indexes
are applied in a single step afterwards.
- Added "pytest-xdist" as a tox dependency, so that the -n flag
in the test command works if this is not already installed.
Pull request courtesy Julien Danjou.
- Fixed issue in PG server default comparison where model-side defaults
configured with Python unicode literals would leak the "u" character
from a ``repr()`` into the SQL used for comparison, creating an invalid
SQL expression, as the server-side comparison feature in PG currently
repurposes the autogenerate Python rendering feature to get a quoted
version of a plain string default.
-------------------------------------------------------------------
Wed Aug 26 14:34:12 UTC 2015 - tbechtold@suse.com
- update to 0.8.2:
- Added workaround in new foreign key option detection feature for MySQL’s
consideration of the “RESTRICT” option being the default, for which no
value is reported from the database; the MySQL impl now corrects for when
the model reports RESTRICT but the database reports nothing. A similar
rule is in the default FK comparison to accommodate for the default
“NO ACTION” setting being present in the model but not necessarily
reported by the database, or vice versa.
- A custom EnvironmentContext.configure.process_revision_directives hook
can now generate op directives within the UpgradeOps and DowngradeOps
containers that will be generated as Python code even when the
--autogenerate flag is False; provided that revision_environment=True,
the full render operation will be run even in “offline” mode.
- Implemented support for autogenerate detection of changes in the ondelete,
onupdate, initially and deferrable attributes of ForeignKeyConstraint
objects on SQLAlchemy backends that support these on reflection (as of
SQLAlchemy 1.0.8 currently Postgresql for all four, MySQL for ondelete
and onupdate only). A constraint object that modifies these values will
be reported as a “diff” and come out as a drop/create of the constraint
with the modified values. The fields are ignored for backends which
don’t reflect these attributes (as of SQLA 1.0.8 this includes SQLite,
Oracle, SQL Server, others).
- Repaired the render operation for the ops.AlterColumnOp object to succeed
when the “existing_type” field was not present.
- Fixed a regression 0.8 whereby the “multidb” environment template failed
to produce independent migration script segments for the output template.
This was due to the reorganization of the script rendering system for 0.8.
To accommodate this change, the MigrationScript structure will in the case
of multiple calls to MigrationContext.run_migrations() produce lists for
the MigrationScript.upgrade_ops and MigrationScript.downgrade_ops attributes;
each UpgradeOps and DowngradeOps instance keeps track of its own upgrade_token
and downgrade_token, and each are rendered individually.
-------------------------------------------------------------------
Fri Aug 21 12:05:28 UTC 2015 - tbechtold@suse.com
- update to 0.8.0:
- Added new command alembic edit. This command takes the same arguments
as alembic show, however runs the target script file within $EDITOR.
Makes use of the python-editor library in order to facilitate the
handling of $EDITOR with reasonable default behaviors across platforms.
Pull request courtesy Michel Albert.
- Added new multiple-capable argument --depends-on to the alembic revision
command, allowing depends_on to be established at the command line level
rather than having to edit the file after the fact. depends_on identifiers
may also be specified as branch names at the command line or directly
within the migration file. The values may be specified as partial
revision numbers from the command line which will be resolved to full
revision numbers in the output file.
- The default test runner via “python setup.py test” is now py.test.
nose still works via run_tests.py.
- The internal system for Alembic operations has been reworked to now
build upon an extensible system of operation objects. New operations can
be added to the op. namespace, including that they are available in custom
autogenerate schemes.
- The internal system for autogenerate been reworked to build upon the
extensible system of operation objects present in #302. As part of this
change, autogenerate now produces a full object graph representing a list
of migration scripts to be written as well as operation objects that will
render all the Python code within them; a new hook
EnvironmentContext.configure.process_revision_directives allows end-user
code to fully customize what autogenerate will do, including not just
full manipulation of the Python steps to take but also what file or files
will be written and where. Additionally, autogenerate is now extensible as
far as database objects compared and rendered into scripts; any new
operation directive can also be registered into a series of hooks that
allow custom database/model comparison functions to run as well as to
render new operation directives into autogenerate scripts.
- Fixed bug in batch mode where the batch_op.create_foreign_key() directive
would be incorrectly rendered with the source table and schema names in
the argument list.
- Fixed bug where in the erroneous case that alembic_version contains
duplicate revisions, some commands would fail to process the version history
correctly and end up with a KeyError. The fix allows the versioning logic
to proceed, however a clear error is emitted later when attempting to
update the alembic_version table.
- Implemented support for BatchOperations.create_primary_key() and
BatchOperations.create_check_constraint(). Additionally, table keyword
arguments are copied from the original reflected table, such as the
“mysql_engine” keyword argument.
- Fixed critical issue where a complex series of branches/merges would
bog down the iteration algorithm working over redundant nodes for millions
of cycles. An internal adjustment has been made so that duplicate nodes are
skipped within this iteration.
- The MigrationContext.stamp() method, added as part of the versioning
refactor in 0.7 as a more granular version of command.stamp(), now includes
the “create the alembic_version table if not present” step in the same
way as the command version, which was previously omitted.
- Fixed bug where foreign key options including “onupdate”, “ondelete” would
not render within the op.create_foreign_key() directive, even though they
render within a full ForeignKeyConstraint directive.
- Repaired warnings that occur when running unit tests against SQLAlchemy
1.0.5 or greater involving the “legacy_schema_aliasing” flag.
- Add python-pytest-cov as BuildRequires

Sat Apr 25 15:53:02 UTC 2015 - benoit.monin@gmx.fr
- 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.

- 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.

- 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

- 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()

- 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.

- 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.

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.
