* Remove old versionadded and versionchangedFederico Caselli2023-04-121-5/+0
| | | | | | | Removed versionadded and versionchanged for version prior to 1.2 since they are no longer useful. Change-Id: I5c53d1188bc5fec3ab4be39ef761650ed8fa6d3e

* Support handle_error for pre_pingMike Bayer2022-05-311-1/+1
| | | | | | | | | | | | | The :meth:`.DialectEvents.handle_error` event is now moved to the :class:`.DialectEvents` suite from the :class:`.EngineEvents` suite, and now participates in the connection pool "pre ping" event for those dialects that make use of disconnect codes in order to detect if the database is live. This allows end-user code to alter the state of "pre ping". Note that this does not include dialects which contain a native "ping" method such as that of psycopg2 or most MySQL dialects.

* pep-484 for sqlalchemy.event; use future annotationsMike Bayer2022-02-151-6/+19
| | | | | | | | | | __future__.annotations mode allows us to use non-string annotations for argument and return types in most cases, but more importantly it removes a large amount of runtime overhead that would be spent in evaluating the annotations.

* upgrade to black 20.8b1Mike Bayer2020-09-281-3/+1
| | | | | | | It's better, the majority of these changes look more readable to me. also found some docstrings that had formatting / quoting issues. Change-Id: I582a45fde3a5648b2f36bab96bad56881321899b
* Documentation updates for 1.4Mike Bayer2020-08-051-10/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * major additions to 1.4 migration doc; removed additional verbosity regarding caching methodology and reorganized the doc to present itself more as a "what's changed" guide * as we now have a path for asyncio, update that doc so that we aren't spreading obsolete information * updates to the 2.0 migration guide with latest info, however this is still an architecture doc and not a migration guide yet, will need further rework. * start really talking about 1.x vs. 2.0 style everywhere. Querying is most of the docs so this is going to be a prominent theme, start getting it to fit in * Add introductory documentation for ORM example sections as these are too sparse * new documentation for do_orm_execute(), many separate sections, adding deprecation notes to before_compile() and similar * new example suites to illustrate do_orm_execute(), with_loader_criteria() * modernized horizontal sharding examples and added a separate example to distinguish between multiple databases and single database w/ multiple tables use case * introducing DEEP ALCHEMY, will use zzzeeksphinx 1.1.6 * no name for the alchemist yet however the dragon's name is Flambé Change-Id: Id6b5c03b1ce9ddb7b280f66792212a0ef0a1c541

* Strong reference listen function wrapped by "once"Mike Bayer2019-08-041-0/+14
| | | | | | | | | | | | | | Fixed issue in event system where using the ``once=True`` flag with dynamically generated listener functions would cause event registration of future events to fail if those listener functions were garbage collected after they were used, due to an assumption that a listened function is strongly referenced. The "once" wrapped is now modified to strongly reference the inner function persistently, and documentation is updated that using "once" does not imply automatic de-registration of listener functions.

| | | | | | | | | | | | | | | | | | These changes should be ported from 1.3 back to 1.0 or possibly 0.9 to the extent they are relevant in each version. In 1.3 we hope to turn all deprecation documentation into warnings. Change-Id: I205186cde161af9389af513a425c62ce90dd54d8

* Post black reformattingMike Bayer2019-01-061-1/+3
| | | | | | | | | | | | | 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 Bayer2019-01-061-4/+7
| | | | | | | | | | | | | | 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.

| | | | | | | | | is being run itself, either from inside the listener or from a concurrent thread, now raises a RuntimeError, as the collection used is now an instance of ``colletions.deque()`` and does not support changes while being iterated. Previously, a plain Python list was used where removal from inside the event itself would produce silent failures. fixes #3163

* - Removal of event listeners is now implemented. The feature isMike Bayer2013-07-261-0/+99
provided via the :func:`.event.remove` function. [ticket:2268] - reorganization of event.py module into a package; with the addition of the docstring work as well as the new registry for removal, there's a lot more code now. the package separates concerns and provides a top-level doc for each subsection of functionality - the remove feature works by providing the EventKey object which associates the user-provided arguments to listen() with a global, weak-referencing registry. This registry stores a collection of _ListenerCollection and _DispatchDescriptor objects associated with each set of arguments, as well as the wrapped function which was applied to that collection. The EventKey can then be recreated for a removal, all the _ListenerCollection and _DispatchDescriptor objects are located, and the correct wrapped function is removed from each one.
