| * Use context managers for threading.Lock()Heckad2020-01-031-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | (zzzeek:) For some reason I thought that threading.Lock() still did not support context managers, at least in Python 2, however this does not seem to be the case.

* Add informative failure modes to _DeferredMapperConfigMike Bayer2019-01-301-0/+11
| | | | | | | | | | | Added some helper exceptions that invoke when a mapping based on :class:`.AbstractConcreteBase`, :class:`.DeferredReflection`, or :class:`.AutoMap` is used before the mapping is ready to be used, which contain descriptive information on the class, rather than falling through into other failure modes that are less informative. Fixes: #4470 Change-Id: I9bc51697f63cedaa7809a0adb17b2398c209e289
* Fix many spell glitchesLele Gaifax2019-01-251-2/+2
| | | | | | | | | | | | This affects mostly docstrings, except in orm/events.py::dispose_collection() where one parameter gets renamed: given that the method is empty, it seemed reasonable to me to fix that too.

* Post black reformattingMike Bayer2019-01-061-5/+7
| | | | | | | | | | | | | 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 Bayer2019-01-061-134/+175
| | | | | | | | | | | | | | 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.

* Mutex on _CONFIGURE_MUTEX in automap.prepare()Mike Bayer2018-05-281-42/+48
| | | | | | | | | | | | Fixed a race condition which could occur if automap :meth:`.AutomapBase.prepare` were used within a multi-threaded context against other threads which may call :func:`.configure_mappers` as a result of use of other mappers. The unfinished mapping work of automap is particularly sensitive to being pulled in by a :func:`.configure_mappers` step leading to errors.

* Protect against cls weakref becoming NoneMike Bayer2017-05-081-2/+2
| | | | | | | | | | Protected against testing "None" as a class in the case where declarative classes are being garbage collected and new automap prepare() operations are taking place concurrently, very infrequently hitting a weakref that has not been fully acted upon after gc.

| | | | | | | | | This allows automap to reflect tables from a schema other than the default without the need to resort to calling MetaData.reflect directly. Change-Id: Ie73cb113bd6d115555c09c5efc33d27ad2c9c512 Pull-request: https://github.com/zzzeek/sqlalchemy/pull/237

| | | | | | | | As per their email ‘Changes to project subdomains’: > Starting today, Read the Docs will start hosting projects from subdomains on the domain readthedocs.io, instead of on readthedocs.org. This change addresses some security concerns around site cookies while hosting user generated data on the same domain as our dashboard. Test Plan: Manually visited all the links I’ve modified.

| | | | | | | | | | | | | | ``cascade="all, delete-orphan"`` automatically on a one-to-many relationship/backref where the foreign key is detected as containing one or more non-nullable columns. This argument is present in the keywords passed to :func:`.automap.generate_relationship` in this case and can still be overridden. Additionally, if the :class:`.ForeignKeyConstraint` specifies ``ondelete="CASCADE"`` for a non-nullable or ``ondelete="SET NULL"`` for a nullable set of columns, the argument ``passive_deletes=True`` is also added to the relationship. Note that not all backends support reflection of ondelete, but backends that do include Postgresql and MySQL. fixes #3210
