| Summary: A database migration tool for SQLAlchemy | |
Alembic is a new database migrations tool, written by the author of SQLAlchemy <http://www.sqlalchemy.org>. A migrations tool offers the following functionality: * Can emit ALTER statements to a database in order to change the structure of tables and other constructs * Provides a system whereby "migration scripts" may be constructed; each script indicates a particular series of steps that can "upgrade" a target database to a new version, and optionally a series of steps that can "downgrade" similarly, doing the same steps in reverse. * Allows the scripts to execute in some sequential manner.

- 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 2018 Tomáš Chvátal <tchvatal@suse.com>
- Do not require old pytest and simply execute the pytest binary
* Thu Nov 01 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 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 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 05 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 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 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 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 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.

* Mon Aug 15 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.

- fix source url
* Fri Jun 03 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 07 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 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 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

environment, but also present on the custom types themselves, by
supplying a method ``compare_against_backend``.

- 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 05 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 05 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.
