* use full context manager flow for future.Engine.begin()Mike Bayer2021-11-011-0/+14
| | | | | | | | | | | | | | | Fixed issue in future :class:`_future.Engine` where calling upon :meth:`_future.Engine.begin` and entering the context manager would not close the connection if the actual BEGIN operation failed for some reason, such as an event handler raising an exception; this use case failed to be tested for the future version of the engine. Note that the "future" context managers which handle ``begin()`` blocks in Core and ORM don't actually run the "BEGIN" operation until the context managers are actually entered. This is different from the legacy version which runs the "BEGIN" operation up front. Fixes: #7272 Change-Id: I9667ac0861a9e007c4b3dfcf0fcf0829038a8711

| * remove case_sensitive create_engine parameterMike Bayer2021-11-011-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | Removed the previously deprecated ``case_sensitive`` parameter from :func:`_sa.create_engine`, which would impact only the lookup of string column names in Core-only result set rows; it had no effect on the behavior of the ORM. The effective behavior of what ``case_sensitive`` refers towards remains at its default value of ``True``, meaning that string names looked up in ``row._mapping`` will match case-sensitively, just like any other Python mapping.

| | | | | | | | | | | | | | | | | | | | based on feedback in #7271, the emphasis on TypeDecorator as a solution to this problem is not very practical. illustrate a series of quick recipes that are useful for debugging purposes to print out a repr() or simple stringify of a parameter without the need to construct custom dialects or types.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | in order to remove LegacyRow / LegacyResult, we have to also lose close_with_result, which connectionless execution relies upon. also includes a new profiles.txt file that's all against py310, as that's what CI is on now. some result counts changed by one function call which was enough to fail the low-count result tests. Replaces Connectable as the common interface between Connection and Engine with EngineEventsTarget. Engine is no longer Connectable. Connection and MockConnection still are.

| |/ |/| | | | | | | | | | | | | | | | | | | | | The :meth:`_engine.Inspector.has_table` method will now consistently check for views of the given name as well as tables. Previously this behavior was dialect dependent, with PostgreSQL, MySQL/MariaDB and SQLite supporting it, and Oracle and SQL Server not supporting it. Third party dialects should also seek to ensure their :meth:`_engine.Inspector.has_table` method searches for views as well as tables for the given name.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixed bug in "relationship to aliased class" feature introduced at :ref:`relationship_aliased_class` where it was not possible to create a loader strategy option targeting an attribute on the target using the :func:`_orm.aliased` construct directly in a second loader option, such as ``selectinload(A.aliased_bs).joinedload(aliased_b.cs)``, without explicitly qualifying using :meth:`_orm.PropComparator.of_type` on the preceding element of the path. Additionally, targeting the non-aliased class directly would be accepted (inappropriately), but would silently fail, such as ``selectinload(A.aliased_bs).joinedload(B.cs)``; this now raises an error referring to the typing mismatch.

* | fix: Update reserved words list of MySQL / MariaDB dialectKevin Kirsche2021-10-201-0/+11
|/ | | | | | | | | | | | | | | | | | | | | | | Reorganized the list of reserved words into two separate lists, one for MySQL and one for MariaDB, so that these diverging sets of words can be managed more accurately; adjusted the MySQL/MariaDB dialect to switch among these lists based on either explicitly configured or server-version-detected "MySQL" or "MariaDB" backend. Added all current reserved words through MySQL 8 and current MariaDB versions including recently added keywords like "lead" . Pull request courtesy Kevin Kirsche. 1. Move reserved words to it's own file. 2. Add missing reserved words from https://mariadb.com/kb/en/reserved-words/ * Note: this only adds MariaDB though links to MySQL, it also does not include the reserved words for Oracle mode, as listed in the link.

* process bulk_update_tuples before cache key or compilationMike Bayer2021-10-191-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | Fixed regression where the use of a :class:`_orm.hybrid_property` attribute or a mapped :func:`_orm.composite` attribute as a key passed to the :meth:`_dml.Update.values` method for an ORM-enabled :class:`_dml.Update` statement, as well as when using it via the legacy :meth:`_orm.Query.update` method, would be processed for incoming ORM/hybrid/composite values within the compilation stage of the UPDATE statement, which meant that in those cases where caching occurred, subsequent invocations of the same statement would no longer receive the correct values. This would include not only hybrids that use the :meth:`_orm.hybrid_property.update_expression` method, but any use of a plain hybrid attribute as well. For composites, the issue instead caused a non-repeatable cache key to be generated, which would break caching and could fill up the statement cache with repeated statements. The :class:`_dml.Update` construct now handles the processing of key/value pairs passed to :meth:`_dml.Update.values` and :meth:`_dml.Update.ordered_values` up front when the construct is first generated, before the cache key has been generated so that the key/value pairs are processed each time, and so that the cache key is generated against the individual column/value pairs that will ultimately be used in the statement.

| * support bind expressions w/ expanding IN; apply to psycopg2Mike Bayer2021-10-151-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixed issue where "expanding IN" would fail to function correctly with datatypes that use the :meth:`_types.TypeEngine.bind_expression` method, where the method would need to be applied to each element of the IN expression rather than the overall IN expression itself. Fixed issue where IN expressions against a series of array elements, as can be done with PostgreSQL, would fail to function correctly due to multiple issues within the "expanding IN" feature of SQLAlchemy Core that was standardized in version 1.4. The psycopg2 dialect now makes use of the :meth:`_types.TypeEngine.bind_expression` method with :class:`_types.ARRAY` to portably apply the correct casts to elements. The asyncpg dialect was not affected by this issue as it applies bind-level casts at the driver level rather than at the compiler level. as part of this commit the "bind translate" feature has been simplified and also applies to the names in the POSTCOMPILE tag to accommodate for brackets.
