------------------------------------------------------------------- Thu Nov 22 21:49:41 UTC 2018 - Arun Persaud <arun@gmx.de> - update to version 1.0.3: * bug + [bug] [mssql] Fixed regression caused by #513, where the logic to consume mssql_include was not correctly interpreting the case where the flag was not present, breaking the op.create_index directive for SQL Server as a whole. References: #516 ------------------------------------------------------------------- Wed Nov 14 13:59:58 UTC 2018 - Tomáš Chvátal <tchvatal@suse.com> - Do not require old pytest and simply execute the pytest binary ------------------------------------------------------------------- Thu Nov 1 22:51:27 UTC 2018 - Arun Persaud <arun@gmx.de> - update to version 1.0.2: * [bug] [autogenerate] The system=True flag on Column, used primarily in conjunction with the Postgresql “xmin” column, now renders within the autogenerate render process, allowing the column to be excluded from DDL. Additionally, adding a system=True column to a model will produce no autogenerate diff as this column is implicitly present in the database.References: #515 * [bug] [mssql] Fixed issue where usage of the SQL Server mssql_include option within a 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.References: #513 ------------------------------------------------------------------- Wed Oct 17 15:32:28 UTC 2018 - Arun Persaud <arun@gmx.de> - specfile: * removed devel from noarch - update to version 1.0.1: * [bug] [commands] Fixed an issue where revision descriptions were essentially being formatted twice. Any revision description that contained characters like %, writing output to stdout will fail because the call to config.print_stdout attempted to format any additional args passed to the function. This fix now only applies string formatting if any args are provided along with the output text. References: #497 * [bug] [autogenerate] Fixed issue where removed method union_update() was used when a customized MigrationScript instance included entries in the .imports data member, raising an AttributeError. References: #512 ------------------------------------------------------------------- Sat Jul 14 01:57:32 UTC 2018 - arun@gmx.de - update to version 1.0.0: * feature + [feature] [general] For Alembic 1.0, Python 2.6 / 3.3 support is being dropped, allowing a fixed setup.py to be built as well as universal wheels. Pull request courtesy Hugo. References: #491 + [feature] [general] With the 1.0 release, Alembic’s minimum SQLAlchemy support version moves to 0.9.0, previously 0.7.9. * bug + [bug] [batch] Fixed issue in batch where dropping a primary key column, then adding it back under the same name but without the primary_key flag, would not remove it from the existing PrimaryKeyConstraint. If a new PrimaryKeyConstraint is added, it is used as-is, as was the case before. References: #502 ------------------------------------------------------------------- Thu Jul 5 21:07:55 UTC 2018 - mcepl@suse.com - update 0.9.10: + Render autogenerate=True if present Fixed issue where "autoincrement=True" would not render for a column that specified it, since as of SQLAlchemy 1.1 this is no longer the default value for "autoincrement". + Make call to declarative_base clear in example. + Use external impl for type rendering The render_type() method of DefaultImpl was hardcoded to only work for SQLAlchemy types. + Implement native boolean check constraint flag in test suite + Use repr for drop_constraint schema + Add recipe for generating Python code for existing tables ------------------------------------------------------------------- Sat Mar 24 00:03:34 UTC 2018 - arun@gmx.de - update to version 0.9.9: * feature + [feature] [commands] Added new flag --indicate-current to the alembic history command. When listing versions, it will include the token “(current)” to indicate the given version is a current head in the target database. Pull request courtesy Kazutaka Mise. References: #481 * bug + [bug] [autogenerate] [mysql] The fix for #455 in version 0.9.6 involving MySQL server default comparison was entirely non functional, as the test itself was also broken and didn’t reveal that it wasn’t working. The regular expression to compare server default values like CURRENT_TIMESTAMP to current_timestamp() is repaired. References: #455 + [bug] [autogenerate] [mysql] Fixed bug where MySQL server default comparisons were basically not working at all due to incorrect regexp added in #455. Also accommodates for MariaDB 10.2 quoting differences in reporting integer based server defaults. References: #483 + [bug] [mysql] [operations] Fixed bug in op.drop_constraint() for MySQL where quoting rules would not be applied to the constraint name. References: #487 ------------------------------------------------------------------- Sat Feb 17 18:31:14 UTC 2018 - arun@gmx.de - 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, only support for op.drop_constraint() to work. References: #479 ------------------------------------------------------------------- Wed Jan 17 04:04:50 UTC 2018 - arun@gmx.de - specfile: * update copyright year - update to version 0.9.7: * [bug] [autogenerate] Fixed regression caused by #421 which would cause case-sensitive quoting rules to interfere with the comparison logic for index names, thus causing indexes to show as 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 case for indexes implicitly generated by unique constraints. Makes use of SQLAlchemy 1.0.x’s improved “duplicates index” metadata and requires at least SQLAlchemy version 1.0.x to function correctly. ------------------------------------------------------------------- Sun Oct 15 22:22:06 UTC 2017 - arun@gmx.de - specfile: * added fdupes - update to version 0.9.6: * feature + [feature] [commands] The alembic history command will now make use of the revision environment env.py unconditionally if the revision_environment configuration flag is set to True. Previously, the environment would only be invoked if the history specification were against a database-stored revision token. References: #447 * bug * [bug] [commands] Fixed a few Python3.6 deprecation warnings by replacing StopIteration with return, as well as using getfullargspec() instead of getargspec() under Python 3. References: #458 * [bug] [commands] An addition to #441 fixed in 0.9.5, we forgot to also filter for the + sign in migration names which also breaks due to the relative migrations feature. References: #441 * [bug] [autogenerate] Fixed bug expanding upon the fix for #85 which adds the correct module import to the “inner” type for an 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 * [bug] [mysql] Fixed bug where server default comparison of CURRENT_TIMESTAMP would fail on MariaDB 10.2 due to a change in how the function is represented by the database during reflection. References: #455 * [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 files as well as versioning files. This includes: locating files 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. ------------------------------------------------------------------- Tue Aug 22 12:41:25 UTC 2017 - tbechtold@suse.com - update to 0.9.5: * see http://alembic.zzzcomputing.com/en/latest/changelog.html#change-0.8.8 * see http://alembic.zzzcomputing.com/en/latest/changelog.html#change-0.8.9 * see http://alembic.zzzcomputing.com/en/latest/changelog.html#change-0.8.10 * see http://alembic.zzzcomputing.com/en/latest/changelog.html#change-0.9.0 * see http://alembic.zzzcomputing.com/en/latest/changelog.html#change-0.9.1 * see http://alembic.zzzcomputing.com/en/latest/changelog.html#change-0.9.2 * see http://alembic.zzzcomputing.com/en/latest/changelog.html#change-0.9.3 * see http://alembic.zzzcomputing.com/en/latest/changelog.html#change-0.9.4 * see http://alembic.zzzcomputing.com/en/latest/changelog.html#change-0.9.5 - convert to singlespec - split -doc package ------------------------------------------------------------------- Sat Jan 28 17:45:34 UTC 2017 - dmueller@suse.com - Update to 0.8.10: * various bugfixes ------------------------------------------------------------------- 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. ------------------------------------------------------------------- Mon Jun 6 12:56:49 UTC 2016 - dmueller@suse.com - fix source url ------------------------------------------------------------------- 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 - Add python-python-editor as Requires and BuildRequires ------------------------------------------------------------------- Fri Jul 24 19:42:39 UTC 2015 - seife+obs@b1-systems.com - fix rhel deps by depending on /usr/sbin/update-alternatives ------------------------------------------------------------------- Thu Jul 23 12:20:15 UTC 2015 - seife+obs@b1-systems.com - update to 0.7.7: * 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. ------------------------------------------------------------------- Tue Jun 9 11:33:03 UTC 2015 - dmueller@suse.com - update to 0.7.6: * Fixed bug where the case of multiple mergepoints that all have the identical set of ancestor revisions would fail to be upgradable, producing an assertion failure. * Added support for type comparison functions to be not just per environment, but also present on the custom types themselves, by supplying a method ``compare_against_backend``. * Fully implemented the :paramref:`~.Operations.batch_alter_table.copy_from` parameter for batch mode * Repaired support for the :meth:`.BatchOperations.create_index` directive, which was mis-named internally such that the operation ------------------------------------------------------------------- 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. ------------------------------------------------------------------- Mon Sep 15 05:25:46 UTC 2014 - tbechtold@suse.com - update to version 0.6.7: * See + http://alembic.readthedocs.org/en/latest/changelog.html#change-0.6.6 + http://alembic.readthedocs.org/en/latest/changelog.html#change-0.6.7 * Fixed bug in MSSQL dialect where "rename table" wasn't using ``sp_rename()`` as is required on SQL Server. Pull request courtesy * Added support for functional indexes when using the :meth:`.Operations.create_index` directive. Within the list of columns, the SQLAlchemy ``text()`` construct can be sent, embedding a literal SQL expression; the :meth:`.Operations.create_index` will perform some hackery behind the scenes to get the :class:`.Index` construct to cooperate. This works around some current limitations in :class:`.Index` which should be resolved on the SQLAlchemy side at some point. * A file named ``__init__.py`` in the ``versions/`` directory is now ignored by Alembic when the collection of version files is retrieved. Pull request courtesy Michael Floering. * Fixed Py3K bug where an attempt would be made to sort None against string values when autogenerate would detect tables across multiple schemas, including the default schema. Pull request courtesy paradoxxxzero. * Autogenerate render will render the arguments within a Table construct using ``*[...]`` when the number of columns/elements is greater than 255. Pull request courtesy Ryan P. Kelly. * Fixed bug where foreign key constraints would fail to render in autogenerate when a schema name was present. Pull request courtesy Andreas Zeidler. * Some deep-in-the-weeds fixes to try to get "server default" comparison working better across platforms and expressions, in particular on the Postgresql backend, mostly dealing with quoting/not quoting of various expressions at the appropriate time and on a per-backend basis. Repaired and tested support for such defaults as Postgresql interval and array defaults. * When a run of Alembic command line fails due to ``CommandError``, the output now prefixes the string with ``"FAILED:"``, and the error is also written to the log output using ``log.error()``. * Liberalized even more the check for MySQL indexes that shouldn't be counted in autogenerate as "drops"; this time it's been reported that an implicitly created index might be named the same as a composite foreign key constraint, and not the actual columns, so we now skip those when detected as well. * Added a new accessor :attr:`.MigrationContext.config`, when used in conjunction with a :class:`.EnvironmentContext` and :class:`.Config`, this config will be returned. Patch courtesy Marc Abramowitz. ------------------------------------------------------------------- Thu Jul 24 11:33:27 UTC 2014 - dmueller@suse.com - update to 0.6.5: * See http://alembic.readthedocs.org/en/latest/changelog.html#change-0.6.5 * Added new argument EnvironmentContext.configure.user_module_prefix * The ScriptDirectory system that loads migration files from a versions/ directory * The command.revision() command now returns the Script object corresponding to the newly generated revision * Added new feature EnvironmentContext.configure.transaction_per_migration, which when True causes the BEGIN/COMMIT pair to incur for each migration individually ------------------------------------------------------------------- Mon Jan 13 13:33:57 UTC 2014 - dmueller@suse.com - update to 0.6.2: * Expanded the size of the “slug” generated by “revision” to 40 characters, which is also configurable by new field truncate_slug_length * Support for autogeneration detection and rendering of indexes and unique constraints has been added * Added new argument mssql_drop_foreign_key to Operations.drop_column() * Bugfixes ------------------------------------------------------------------- Thu Oct 24 10:58:37 UTC 2013 - speilicke@suse.com - Require python-setuptools instead of distribute (upstreams merged) ------------------------------------------------------------------- Thu Aug 8 20:36:51 UTC 2013 - dmueller@suse.com - update to 0.6.0: * [feature] Added new kw argument to EnvironmentContext.configure() include_object. * [feature] The output of the alembic history command is now expanded. * [feature] Added alembic.config.Config.cmd_opts attribute, allows access to the argparse options passed to the alembic runner.(link) * [feature] Added new command line argument -x, allows extra arguments to be appended to the command line which can be consumed within an env.py script by looking at context.config.cmd_opts.x, or more simply a new method EnvironmentContext.get_x_argument().(link) * [feature] Added -r argument to alembic history command, allows specification of [start]:[end] to view a slice of history. * [feature] Source base is now in-place for Python 2.6 through 3.3, without the need for 2to3. * [feature] Added new kw argument to EnvironmentContext.configure() include_object. ------------------------------------------------------------------- Sun Apr 14 15:53:22 UTC 2013 - p.drouand@gmail.com - Update to version 0.5.0 + added version_table_schema argument to EnvironmentContext.configure(), complements the version_table argument to set an optional remote schema for the version table. + added output_encoding option to EnvironmentContext.configure(), used with --sql mode to apply an encoding to the output stream. + added Operations.create_primary_key() operation, will genenerate an ADD CONSTRAINT for a primary key. + upgrade and downgrade commands will list the first line of the docstring out next to the version number. + added –head-only option to “alembic current”, will print current version plus the symbol “(head)” if this version is the head or not. + the rendering of any construct during autogenerate can be customized, in particular to allow special rendering for user-defined column, constraint subclasses, using new render _item argument to EnvironmentContext.configure(). + fix format of RENAME for table that includes schema with Postgresql; the schema name shouldn’t be in the “TO” field. + fix bug whereby double quoting would be applied to target column name during an sp_rename operation. + fix transactional_ddl flag for SQLite, MySQL dialects set to False. MySQL doesn’t support it, SQLite does but current pysqlite driver does not. + fix Autogenerate will render additional table keyword arguments like “mysql_engine” and others within op.create_table(). + fix bug whereby create_index() would include in the constraint columns that are added to all Table objects using events, externally to the generation of the constraint. This is the same issue that was fixed for unique constraints in version 0.3.2. + fix worked around a backwards-incompatible regression in Python3.3 regarding argparse; running “alembic” with no arguments now yields an informative error in py3.3 as with all previous versions. + fix host of argument name changes within migration operations for consistency. Keyword arguments will continue to work on the old name for backwards compatibility, however required positional arguments will not: * Operations.alter_column() - name -> new_column_name - old name will work for backwards compatibility. * Operations.create_index() - tablename -> table_name - argument is positional. * Operations.drop_index() - tablename -> table_name - old name will work for backwards compatibility. * Operations.drop_constraint() - tablename -> table_name - argument is positional. * Operations.drop_constraint() - type -> type_ - old name will work for backwards compatibility + SQLAlchemy 0.6 is no longer supported by Alembic - minimum version is 0.7.3, full support is as of 0.7.9. - Initial python3 support ------------------------------------------------------------------- Thu Jan 17 12:31:01 UTC 2013 - toddrme2178@gmail.com - Set nose version requirement ------------------------------------------------------------------- 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. ------------------------------------------------------------------- Mon Jan 14 16:00:10 UTC 2013 - saschpe@suse.de - Disable testsuite on SLE ------------------------------------------------------------------- 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. ------------------------------------------------------------------- Wed Mar 7 08:25:45 UTC 2012 - saschpe@suse.de - Initial version
