Re-implement c version immutabledict / processors / resultproxy / utils with cython. Performance is in general in par or better than the c version Added a collection module that has cython version of OrderedSet and IdentitySet Added a new test/perf file to compare the implementations. Run ``python test/perf/compiled_extensions.py all`` to execute the comparison test. See results here: https://docs.google.com/document/d/1nOcDGojHRtXEkuy4vNXcW_XOJd9gqKhSeALGG3kYr6A/edit?usp=sharing Fixes: #7256 Change-Id: I2930ef1894b5048210384728118e586e813f6a76 Signed-off-by: Federico Caselli <cfederico87@gmail.com>
Implemented support for the test suite to run correctly under Pytest 7. Previously, only Pytest 6.x was supported for Python 3, however the version was not pinned on the upper bound in tox.ini. Pytest is not pinned in tox.ini to be lower than version 8 so that SQLAlchemy versions released with the current codebase will be able to be tested under tox without changes to the environment. Much thanks to the Pytest developers for their help with this issue. Change-Id: I3b12166199be2b913ee16e78b3ebbff415654396

Fixed regression where the :meth:`_engine.CursorResult.fetchmany` method would fail to autoclose a server-side cursor (i.e. when ``stream_results`` or ``yield_per`` is in use, either Core or ORM oriented results) when the results were fully exhausted. All :class:`_result.Result` objects will now consistently raise :class:`_exc.ResourceClosedError` if they are used after a hard close, which includes the "hard close" that occurs after calling "single row or value" methods like :meth:`_result.Result.first` and :meth:`_result.Result.scalar`. This was already the behavior of the most common class of result objects returned for Core statement executions, i.e. those based on :class:`_engine.CursorResult`, so this behavior is not new. However, the change has been extended to properly accommodate for the ORM "filtering" result objects returned when using 2.0 style ORM queries, which would previously behave in "soft closed" style of returning empty results, or wouldn't actually "soft close" at all and would continue yielding from the underlying cursor. As part of this change, also added :meth:`_result.Result.close` to the base :class:`_result.Result` class and implemented it for the filtered result implementations that are used by the ORM, so that it is possible to call the :meth:`_engine.CursorResult.close` method on the underlying :class:`_engine.CursorResult` when the the ``yield_per`` execution option is in use to close a server side cursor before remaining ORM results have been fetched. This was again already available for Core result sets but the change makes it available for 2.0 style ORM results as well. Fixes: #7274 Change-Id: Id4acdfedbcab891582a7f8edd2e2e7d20d868e53

Adapted from 55e64f857daeb6057b85ff67297a774b when we previously started a 2.0 branch. Change-Id: Ib5af75df94b23104eebe0e918adcf979d798ea3b
most of the work for aliased / from_joinpoint has been done already as I added all new tests for these and moved most aliased/from_joinpoint to test/orm/test_deprecations.py already Change-Id: Ia23e332dec183de17b2fb9d89d946af8d5e89ae7
Implemented proper ``__reduce__()`` methods for all SQLAlchemy exception objects to ensure they all support clean round trips when pickling, as exception objects are often serialized for the purposes of various debugging tools.
