| | | | | | | | | | autogenerate will skip this also. Pull request courtesy Dj Gilcrease. fixes #28 - The :paramref:`.EnvironmentContext.configure.version_table` and :paramref:`.EnvironmentContext.configure.version_table_schema` arguments are now honored during the autogenerate process, such that these names will be used as the "skip" names on both the database reflection and target metadata sides. fixes #77

* Eliminate {} (dict) default arg value for `opts`Marc Abramowitz2014-05-281-1/+4

* - changelog + test for MigrationContext.configMike Bayer2014-05-251-1/+5

* Add EnvironmentContext and Config to MigrationContextMarc Abramowitz2014-05-191-2/+12
| | | | | | | | This lets migrations do stuff like: op.get_context().config.get_main_option('schema') where `schema` is a custom option that I added to alembic.ini
* - Added new feature ↵Mike Bayer2014-05-021-19/+52
| | | | | | | | | | :paramref:`.EnvironmentContext.configure.transaction_per_migration`, which when True causes the BEGIN/COMMIT pair to incur for each migration individually, rather than for the whole series of migrations. This is to assist with some database directives that need to be within individual transactions, without the need to disable transactional DDL entirely. fixes #201
* Fixes to Py3k in-place compatibity regarding output encoding and related;Mike Bayer2013-11-211-6/+6
| | | | | | | the use of the new io.* package introduced some incompatibilities on Py2k. These should be resolved, due to the introduction of new adapter types for translating from io.* to Py2k file types, StringIO types. Thanks to Javier Santacruz for help with this.
* Fixes stdout --sql output in python2Javier Santacruz2013-10-171-5/+6
| | | | | | | | | When output_encoding is set, wraps the output buffer into a io.TextIOWrapper class This means that the output_buffer has to be a io.IOBase instance in order to work along with the TextIOWrapper Handles wrapping when the buffer is Python2 stdtout, which has 'file' type Adds test for this situation
* Fix calling of custom type compare functionMaarten van Schaik2013-08-281-1/+1
|
* Added new kw argument to :meth:`.EnvironmentContext.configure`Mike Bayer2013-07-111-3/+5
| | | | | | | | | | ``include_object``. This is a more flexible version of the ``include_symbol`` argument which allows filtering of columns as well as tables from the autogenerate process, and in the future will also work for types, constraints and other constructs. The fully constructed schema object is passed, including its name and type as well as a flag indicating if the object is from the local application metadata or is reflected.
* - will call this 0.6Mike Bayer2013-04-121-2/+2
| | | | | | | | | | | | | | | | | - cleanup unused symbols in compat - move any remaining conditional import switches out to compat - pretty sure anything we use for a buffer will have flush() - I can see that using the new io.* stuff means codecs isn't too smooth here, but removed the double-wrap check in migration.py which seems to be due to the bytesio setup in the test suite, simplified this so that an encoding-writing test just writes to BytesIO - removed all "from __future__ import with_statement" - i think when we load_source(), that file might not be ascii so we need to open as bytes - make encoding an explcit argument in test suite write_script() - sort the columns in autogenerate so that the autogen tests run consistently on python3.3, seems to have a very random set ordering, also loosen up an ordered check in test_op

* Use relative importsHong Minhee2013-04-111-5/+6
| | | | | | | | | | | | | | | | | | | | | This change does not affect to any behaviors of it, but is just stylish improvements to remove 2to3 dependency. 1. All old-style absolute imports e.g. `from alembic import util` are replaced by relative imports e.g. `from . import util`. 2. Use of proxy modules (`alembic.op` and `alembic.context`) are replaced by deferred import patterns, but these modules still exist. 3. Imports are grouped by 3 types of their origins (standard libraries, third party libraries, and local modules) and blank lines are put between each group of imports. This style is from PEP 8: <http://www.python.org/dev/peps/pep-0008/#imports> For stylish change, I can't do that much, because it was intentionally done as it was by the author. If the author will allow me to make it more closer to PEP 8 style, I will do that as well.

* - move to 0.3 as we are changing APIrel_0_3_0Mike Bayer2012-04-051-20/+75
| | | | | | | | | | | | | | | | | | | | | - [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.
