* Add __reduce_ex__ to MutableList; add compat for older picklesMike Bayer2019-04-091-1/+1
| | | | | | | | | | | | | | | | | | Fixed bug where using ``copy.copy()`` or ``copy.deepcopy()`` on :class:`.MutableList` would cause the items within the list to be duplicated, due to an inconsistency in how Python pickle and copy both make use of ``__getstate__()`` and ``__setstate__()`` regarding lists. In order to resolve, a ``__reduce_ex__`` method had to be added to :class:`.MutableList`. In order to maintain backwards compatibility with existing pickles based on ``__getstate__()``, the ``__setstate__()`` method remains as well; the test suite asserts that pickles made against the old version of the class can still be deserialized by the pickle module. Also modified sqlalchemy.testing.util.picklers to return picklers all the way through pickle.HIGHEST_PROTOCOL. Fixes: #4603 Change-Id: I7f78b9cfb89d59a706248536c553dc5e1d987b88

* Post black reformattingMike Bayer2019-01-061-2/+8
| | | | | | | | | | | | | Applied on top of a pure run of black -l 79 in I7eda77fed3d8e73df84b3651fd6cfcfe858d4dc9, this set of changes resolves all remaining flake8 conditions for those codes we have enabled in setup.cfg. Included are resolutions for all remaining flake8 issues including shadowed builtins, long lines, import order, unused imports, duplicate imports, and docstring issues.

* Run black -l 79 against all source filesMike Bayer2019-01-061-25/+41
| | | | | | | | | | | | | | This is a straight reformat run using black as is, with no edits applied at all. The black run will format code consistently, however in some cases that are prevalent in SQLAlchemy code it produces too-long lines. The too-long lines will be resolved in the following commit that will resolve all remaining flake8 issues including shadowed builtins, long lines, import order, unused imports, duplicate imports, and docstring issues.

* Ensure we check for boolean condition when we inspect __exit__()Mike Bayer2017-07-241-1/+1
| | | | | | | | Fixed issue in testing fixtures which was incompatible with a change made as of Python 3.6.2 involving context managers. Change-Id: I0f12aa6cc15cba89153f7e4888ac347e7ce599c7 Fixes: #4034

* - use schema argument correctly when we are dropping for a schemaMike Bayer2016-01-281-1/+1
|
* - Fixed regression regarding the declarative ``__declare_first__``Mike Bayer2015-04-241-0/+11
| | | | | | and ``__declare_last__`` accessors where these would no longer be called on the superclass of the declarative base. fixes #3383
* - repair a regression caused by #3282, where we no longer wereMike Bayer2015-04-221-1/+2
| | | | | | | | | | applying any topological sort to tables on SQLite. See the changelog for details, but we now continue to sort tables for SQLite on DROP, prohibit the sort from considering alter, and only warn if we encounter an unresolvable cycle, in which case, then we forego the ordering. use_alter as always is used to break such a cycle. fixes #3378

* - additional test adjustments for pypy / psycopg2cffi. ThisMike Bayer2015-01-261-0/+4
| | | | | | | | | | consists mainly of adjusting fixtures to ensure connections are closed explicitly. psycopg2cffi also handles unicode bind parameter names differently than psycopg2, and seems to possibly have a little less control over floating point values at least in one test which is marked as a "fail", though will see if it runs differently on linux than osx.. - changelog for psycopg2cffi, fixes #3052
* - restate sort_tables in terms of a more fine grainedMike Bayer2015-01-011-0/+55
| | | | | | | | | | | | | sort_tables_and_constraints function. - The DDL generation system of :meth:`.MetaData.create_all` and :meth:`.Metadata.drop_all` has been enhanced to in most cases automatically handle the case of mutually dependent foreign key constraints; the need for the :paramref:`.ForeignKeyConstraint.use_alter` flag is greatly reduced. The system also works for constraints which aren't given a name up front; only in the case of DROP is a name required for at least one of the constraints involved in the cycle. fixes #3282
* - Made a small adjustment to the mechanics of lazy loading,Mike Bayer2014-08-281-1/+3
| | | | | | | | | | such that it has less chance of interfering with a joinload() in the very rare circumstance that an object points to itself; in this scenario, the object refers to itself while loading its attributes which can cause a mixup between loaders. The use case of "object points to itself" is not fully supported, but the fix also removes some overhead so for now is part of testing. fixes #3145

become an externally usable package but still remains within the main sqlalchemy parent package. in this system, we use kind of an ugly hack to get the noseplugin imported outside of the "sqlalchemy" package, while still making it available within sqlalchemy for usage by third party libraries.
