* Warn when caching is disabled / documentMike Bayer2021-12-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds new warnings for all elements that don't indicate their caching behavior, including user-defined ClauseElement subclasses and third party dialects. it additionally adds new documentation to discuss an apparent performance degradation in 1.4 when caching is disabled as a result in the significant expense incurred by ORM lazy loaders, which in 1.3 used BakedQuery so were actually cached. As a result of adding the warnings, a fair degree of lesser used SQL expression objects identified that they did not define caching behavior so would have been producing ``[no key]``, including PostgreSQL constructs ``hstore`` and ``array``. These have been amended to use inherit cache where appropriate. "on conflict" constructs in PostgreSQL, MySQL, SQLite still explicitly don't generate a cache key at this time. The change also adds a test for all constructs via assert_compile() to assert they will not generate cache warnings. Fixes: #7394 Change-Id: I85958affbb99bfad0f5efa21bc8f2a95e7e46981

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new system so that PostgreSQL and other dialects have a reliable way to add casts to bound parameters in SQL statements, replacing previous use of setinputsizes() for PG dialects. rationale: 1. psycopg3 will be using the same SQLAlchemy-side "setinputsizes" as asyncpg, so we will be seeing a lot more of this 2. the full rendering that SQLAlchemy's compilation is performing is in the engine log as well as error messages. Without this, we introduce three levels of SQL rendering, the compiler, the hidden "setinputsizes" in SQLAlchemy, and then whatever the DBAPI driver does. With this new approach, users reporting bugs etc. will be less confused that there are as many as two separate layers of "hidden rendering"; SQLAlchemy's rendering is again fully transparent 3. calling upon a setinputsizes() method for every statement execution is expensive. this way, the work is done behind the caching layer 4. for "fast insertmany()", I also want there to be a fast approach towards setinputsizes. As it was, we were going to be taking a SQL INSERT with thousands of bound parameter placeholders and running a whole second pass on it to apply typecasts. this way, we will at least be able to build the SQL string once without a huge second pass over the whole string 5. psycopg2 can use this same system for its ARRAY casts 6. the general need for PostgreSQL to have lots of type casts is now mostly in the base PostgreSQL dialect and works independently of a DBAPI being present. dependence on DBAPI symbols that aren't complete / consistent / hashable is removed I was originally going to try to build this into bind_expression(), but it was revealed this worked poorly with custom bind_expression() as well as empty sets. the current impl also doesn't need to run a second expression pass over the POSTCOMPILE sections, which came out better than I originally thought it would.

* Support lightweight compiler column elements w/ slotsMike Bayer2021-11-221-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | the _CompileLabel class included ``__slots__`` but these weren't used as the superclasses included slots. Create a ``__slots__`` superclass for ``ClauseElement``, creating a new class of compilable SQL elements that don't include heavier features like caching, annotations and cloning, which are meant to be used only in an ad-hoc compiler fashion. Create new ``CompilerColumnElement`` from that which serves in column-oriented contexts, but similarly does not include any expression operator support as it is intended to be used only to generate a string. Apply this to both ``_CompileLabel`` as well as PostgreSQL ``_ColonCast``, which does not actually subclass ``ColumnElement`` as this class has memoized attributes that aren't worth changing, and does not include SQL operator capabilities as these are not needed for these compiler-only objects. this allows us to more inexpensively add new ad-hoc labels / casts etc. at compile time, as we will be seeking to expand out the typecasts that are needed for PostgreSQL dialects in a subsequent patch.

| * fully support isolation_level parameter in base dialectMike Bayer2021-11-181-16/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Generalized the :paramref:`_sa.create_engine.isolation_level` parameter to the base dialect so that it is no longer dependent on individual dialects to be present. This parameter sets up the "isolation level" setting to occur for all new database connections as soon as they are created by the connection pool, where the value then stays set without being reset on every checkin. The :paramref:`_sa.create_engine.isolation_level` parameter is essentially equivalent in functionality to using the :paramref:`_engine.Engine.execution_options.isolation_level` parameter via :meth:`_engine.Engine.execution_options` for an engine-wide setting. The difference is in that the former setting assigns the isolation level just once when a connection is created, the latter sets and resets the given level on each connection checkout.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The :paramref:`_sa.create_engine.implicit_returning` parameter is deprecated on the :func:`_sa.create_engine` function only; the parameter remains available on the :class:`_schema.Table` object. This parameter was originally intended to enable the "implicit returning" feature of SQLAlchemy when it was first developed and was not enabled by default. Under modern use, there's no reason this parameter should be disabled, and it has been observed to cause confusion as it degrades performance and makes it more difficult for the ORM to retrieve recently inserted server defaults. The parameter remains available on :class:`_schema.Table` to specifically suit database-level edge cases which make RETURNING infeasible, the sole example currently being SQL Server's limitation that INSERT RETURNING may not be used on a table that has INSERT triggers on it. Also removed from the Oracle dialect some logic that would upgrade an Oracle 8/8i server version to use implicit returning if the parameter were explictly passed; these versions of Oracle still support RETURNING so the feature is now enabled for all Oracle versions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

For standard pep-249 DBAPIs, this will always be the same object as that of the ``dbapi_connection``. For an asyncio driver, it will be the underlying asyncio-only connection object.

* | ignore and warn for native_enum=False with pg.ENUM datatypeMike Bayer2021-09-101-4/+19
|/ | | | | | | | | | | | | | | any UPPERCASE datatype refers to that exact type name rendered on the database. So PG's ENUM must render "ENUM" and is "native" by definition. warn if this flag is passed. The :class:`_postgresql.ENUM` datatype is PostgreSQL-native and therefore should not be used with the ``native_enum=False`` flag. This flag is now ignored if passed to the :class:`_postgresql.ENUM` datatype and a warning is emitted; previously the flag would cause the type object to fail to function correctly.

* fix linter JOIN logic; fix PostgreSQL ARRAY op comparisonMike Bayer2021-08-151-0/+33
| | | | | | | | | | | | | | | | | | | Adjusted the "from linter" warning feature to accommodate for a chain of joins more than one level deep where the ON clauses don't explicitly match up the targets, such as an expression such as "ON TRUE". This mode of use is intended to cancel the cartesian product warning simply by the fact that there's a JOIN from "a to b", which was not working for the case where the chain of joins had more than one element. this incurs a bit more compiler overhead that comes out in profiling but is not extensive. Added the "is_comparison" flag to the PostgreSQL "overlaps", "contained_by", "contains" operators, so that they work in relevant ORM contexts as well as in conjunction with the "from linter" feature.

| * dont qualify literal_binds with literal_executeMike Bayer2021-08-072-0/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | this appears to be unnecessary and prevents end-user literal_binds case from working. Fixed issue where the ``literal_binds`` compiler flag, as used externally to render bound parameters inline, would fail to work when used with a certain class of parameters known as "literal_execute", which covers things like LIMIT and OFFSET values for dialects where the drivers don't allow a bound parameter, such as SQL Server's "TOP" clause. The issue locally seemed to affect only the MSSQL dialect. Fixes: #6863 Change-Id: Ia74cff5b0107b129a11b9b965883552b2962e449
