* establish mypy / typing approach for v2.0Mike Bayer2022-02-131-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | large patch to get ORM / typing efforts started. this is to support adding new test cases to mypy, support dropping sqlalchemy2-stubs entirely from the test suite, validate major ORM typing reorganization to eliminate the need for the mypy plugin. * New declarative approach which uses annotation introspection, fixes: #7535 * Mapped[] is now at the base of all ORM constructs that find themselves in classes, to support direct typing without plugins * Mypy plugin updated for new typing structures * Mypy test suite broken out into "plugin" tests vs. "plain" tests, and enhanced to better support test structures where we assert that various objects are introspected by the type checker as we expect. as we go forward with typing, we will add new use cases to "plain" where we can assert that types are introspected as we expect. * For typing support, users will be much more exposed to the class names of things. Add these all to "sqlalchemy" import space. * Column(ForeignKey()) no longer needs to be `@declared_attr` if the FK refers to a remote table * composite() attributes mapped to a dataclass no longer need to implement a `__composite_values__()` method * with_variant() accepts multiple dialect names Change-Id: I22797c0be73a8fbbd2d6f5e0c0b7258b17fe145d Fixes: #7535 Fixes: #7551 References: #6810
* join to existing mark expr with "and"Mike Bayer2022-01-251-6/+6
| | | | | | | | | | | ca48f461b2dcac2970829e4e0 considered an existing mark expression plus legacy tags to be an error condition; however these can be joined by "and" and will in our use case do the right thing. The github action scripts make use of legacy tags. We can change that also but I want to just make sure this combination works fully as well. Change-Id: Ifc506de3dd961c01d68d594ec2f5b2c9a0bbad31
* replace test tags with pytest.markMike Bayer2022-01-252-85/+90
| | | | | | | | | | | | | | | | | | | | | | | | | | replaced the __tags__ class attribute and the --exclude-tags / --include-tags test runner options with regular pytest.mark names so that we can take advantage of mark expressions. options --nomemory, --notimingintensive, --backend-only, --exclude-tags, --include-tags remain as legacy but make use of pytest mark for implemementation. Added a "mypy" mark for the section of tests that are doing mypy integration tests. The __backend__ and __sparse_backend__ class attributes also use pytest marks for their implementation, which also allows the marks "backend" and "sparse_backend" to be used explicitly. Also removed the no longer used "--cdecimal" option as this was python 2 specific. in theory, the usage of pytest marks could expand such that the whole exclusions system would be based on it, but this does not seem to have any advantage at the moment.

* dont use exception catches for warnings; modernize xdist detectionMike Bayer2022-01-221-12/+7
| | | | | | | | | | | | | | | | | Improvements to the test suite's integration with pytest such that the "warnings" plugin, if manually enabled, will not interfere with the test suite, such that third parties can enable the warnings plugin or make use of the ``-W`` parameter and SQLAlchemy's test suite will continue to pass. Additionally, modernized the detection of the "pytest-xdist" plugin so that plugins can be globally disabled using PYTEST_DISABLE_PLUGIN_AUTOLOAD=1 without breaking the test suite if xdist were still installed. Warning filters that promote deprecation warnings to errors are now localized to SQLAlchemy-specific warnings, or within SQLAlchemy-specific sources for general Python deprecation warnings, so that non-SQLAlchemy deprecation warnings emitted from pytest plugins should also not impact the test suite.

| * factor out UnboundLoad and rearchitect strategy_options.pyMike Bayer2021-12-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The architecture of Load is mostly rewritten here. The change includes removal of the "pluggable" aspect of the loader options, which would patch new methods onto Load. This has been replaced by normal methods that respond normally to typing annotations. As part of this change, the bake_loaders() and unbake_loaders() options, which have no effect since 1.4 and were unlikely to be in any common use, have been removed. Additionally, to support annotations for methods that make use of @decorator, @generative etc., modified format_argspec_plus to no longer return "args", instead returns "grouped_args" which is always grouped and allows return annotations to format correctly.

* | implement cython for cache_anon_map, prefix_anon_mapMike Bayer2021-12-211-0/+15
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These are small bits where cache_anon_map in particular is part of the cache key generation scheme which is a key target for cython. changing such a tiny element of the cache key gen is doing basically nothing yet, as the cython impl is mostly the exact same speed as the python one. I guess for cython to be effective we'd need to redo the whole cache key generation and possibly not use the same kinds of structures, which might not be very easy to do. Additionally, some cython runtime import errors are being observed on jenkins, add an upfront check to the test suite to indicate if the expected build succeeded when REQUIRE_SQLALCHEMY_CEXT is set.

* adapt pytest plugin to support pytest v7Federico Caselli2021-11-293-78/+90
| | | | | | | | | | | | 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

* Surface driver connection object when using a proxied dialectFederico Caselli2021-09-171-5/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | Improve the interface used by adapted drivers, like the asyncio ones, to access the actual connection object returned by the driver. The :class:`_engine._ConnectionRecord` and :class:`_engine._ConnectionFairy` now have two new attributes: * ``dbapi_connection`` always represents a DBAPI compatible object. For pep-249 drivers, this is the DBAPI connection as it always has been, previously accessed under the ``.connection`` attribute. For asyncio drivers that SQLAlchemy adapts into a pep-249 interface, the returned object will normally be a SQLAlchemy adaption object called :class:`_engine.AdaptedConnection`. * ``driver_connection`` always represents the actual connection object maintained by the third party pep-249 DBAPI or async driver in use. 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. The ``.connection`` attribute remains available and is now a legacy alias of ``.dbapi_connection``. Fixes: #6832 Change-Id: Ib72f97deefca96dce4e61e7c38ba430068d6a82e

| | | | | | | | | | Add --mypy-extra-test-path parameter to pytest execution to list extra directories to load test files from.

* Ensure sparse backend selection sorts on driver alsoMike Bayer2021-04-221-0/+1
| | | | | | | | | | | | | | | | Because we have --dbdriver now, we usually have lots of db drivers queued up which affect the selection of backend tests. the sort in possible_configs_for_cls() is used so that when we are only picking some backends due to the sparse flag, we get the same answer each time otherwise pytest-xdist raises an error if two workers have different tests. adding the sort for driver fixes an issue on jenkins master build where the memusage test run frequently failed due to mismatched test collection.

* CAST the elements in ARRAYs when using psycopg2Federico Caselli2021-03-151-1/+3
| | | | | | | | | | | | Adjusted the psycopg2 dialect to emit an explicit PostgreSQL-style cast for bound parameters that contain ARRAY elements. This allows the full range of datatypes to function correctly within arrays. The asyncpg dialect already generated these internal casts in the final statement. This also includes support for array slice updates as well as the PostgreSQL-specific :meth:`_postgresql.ARRAY.contains` method. Fixes: #6023 Change-Id: Ia7519ac4371a635f05ac69a3a4d0f4e6d2f04cad
* Create explicit GC ordering between ConnectionFairy/ConnectionRecordMike Bayer2021-01-151-0/+1
| | | | | | | | | | | | | | Fixed issue where connection pool would not return connections to the pool or otherwise be finalized upon garbage collection under pypy if the checked out connection fell out of scope without being closed. This is a long standing issue due to pypy's difference in GC behavior that does not call weakref finalizers if they are relative to another object that is also being garbage collected. A strong reference to the related record is now maintained so that the weakref has a strong-referenced "base" to trigger off of. Fixes: #5842 Change-Id: Id5448fdacb6cceaac1ea40b2fbc851f052ed8e86
* reinvent xdist hooks in terms of pytest fixturesMike Bayer2021-01-134-46/+298
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To allow the "connection" pytest fixture and others work correctly in conjunction with setup/teardown that expects to be external to the transaction, remove and prevent any usage of "xdist" style names that are hardcoded by pytest to run inside of fixtures, even function level ones. Instead use pytest autouse fixtures to implement our own r"setup|teardown_test(?:_class)?" methods so that we can ensure function-scoped fixtures are run within them. A new more explicit flow is set up within plugin_base and pytestplugin such that the order of setup/teardown steps, which there are now many, is fully documented and controllable. New granularity has been added to the test teardown phase to distinguish between "end of the test" when lock-holding structures on connections should be released to allow for table drops, vs. "end of the test plus its teardown steps" when we can perform final cleanup on connections and run assertions that everything is closed out. From there we can remove most of the defensive "tear down everything" logic inside of engines which for many years would frequently dispose of pools over and over again, creating for a broken and expensive connection flow. A quick test shows that running test/sql/ against a single Postgresql engine with the new approach uses 75% fewer new connections, creating 42 new connections total, vs. 164 new connections total with the previous system. As part of this, the new fixtures metadata/connection/future_connection have been integrated such that they can be combined together effectively. The fixture_session(), provide_metadata() fixtures have been improved, including that fixture_session() now strongly references sessions which are explicitly torn down before table drops occur afer a test. Major changes have been made to the ConnectionKiller such that it now features different "scopes" for testing engines and will limit its cleanup to those testing engines corresponding to end of test, end of test class, or end of test session. The system by which it tracks DBAPI connections has been reworked, is ultimately somewhat similar to how it worked before but is organized more clearly along with the proxy-tracking logic. A "testing_engine" fixture is also added that works as a pytest fixture rather than a standalone function. The connection cleanup logic should now be very robust, as we now can use the same global connection pools for the whole suite without ever disposing them, while also running a query for PostgreSQL locks remaining after every test and assert there are no open transactions leaking between tests at all. Additional steps are added that also accommodate for asyncio connections not explicitly closed, as is the case for legacy sync-style tests as well as the async tests themselves. As always, hundreds of tests are further refined to use the new fixtures where problems with loose connections were identified, largely as a result of the new PostgreSQL assertions, many more tests have moved from legacy patterns into the newest. An unfortunate discovery during the creation of this system is that autouse fixtures (as well as if they are set up by @pytest.mark.usefixtures) are not usable at our current scale with pytest 4.6.11 running under Python 2. It's unclear if this is due to the older version of pytest or how it implements itself for Python 2, as well as if the issue is CPU slowness or just large memory use, but collecting the full span of tests takes over a minute for a single process when any autouse fixtures are in place and on CI the jobs just time out after ten minutes. So at the moment this patch also reinvents a small version of "autouse" fixtures when py2k is running, which skips generating the real fixture and instead uses two global pytest fixtures (which don't seem to impact performance) to invoke the "autouse" fixtures ourselves outside of pytest. This will limit our ability to do more with fixtures until we can remove py2k support. py.test is still observed to be much slower in collection in the 4.6.11 version compared to modern 6.2 versions, so add support for new TOX_POSTGRESQL_PY2K and TOX_MYSQL_PY2K environment variables that will run the suite for fewer backends under Python 2. For Python 3 pin pytest to modern 6.2 versions where performance for collection has been improved greatly. Includes the following improvements: Fixed bug in asyncio connection pool where ``asyncio.TimeoutError`` would be raised rather than :class:`.exc.TimeoutError`. Also repaired the :paramref:`_sa.create_engine.pool_timeout` parameter set to zero when using the async engine, which previously would ignore the timeout and block rather than timing out immediately as is the behavior with regular :class:`.QueuePool`. For asyncio the connection pool will now also not interact at all with an asyncio connection whose ConnectionFairy is being garbage collected; a warning that the connection was not properly closed is emitted and the connection is discarded. Within the test suite the ConnectionKiller is now maintaining strong references to all DBAPI connections and ensuring they are released when tests end, including those whose ConnectionFairy proxies are GCed. Identified cx_Oracle.stmtcachesize as a major factor in Oracle test scalability issues, this can be reset on a per-test basis rather than setting it to zero across the board. the addition of this flag has resolved the long-standing oracle "two task" error problem. For SQL Server, changed the temp table style used by the "suite" tests to be the double-pound-sign, i.e. global, variety, which is much easier to test generically. There are already reflection tests that are more finely tuned to both styles of temp table within the mssql test suite. Additionally, added an extra step to the "dropfirst" mechanism for SQL Server that will remove all foreign key constraints first as some issues were observed when using this flag when multiple schemas had not been torn down. Identified and fixed two subtle failure modes in the engine, when commit/rollback fails in a begin() context manager, the connection is explicitly closed, and when "initialize()" fails on the first new connection of a dialect, the transactional state on that connection is still rolled back.

| | | | | | | | | | | | | | | in I4940d184a4dc790782fcddfb9873af3cca844398 we reworked how async tests run but apparently the async tests in test/ext/asyncio are reporting success without being run. This patch pushes pytestplugin further so that it won't instrument any test or function overall that declares itself async. This removes the need for the __async_wrap__ flag and also allows us to use a more strict "run_async_test" function that always runs the asyncio event loop from the top. Also start working asyncio into main testing suite. Change-Id: If7144e951a9db67eb7ea73b377f81c4440d39819

* Repair mssql dep tests; have __only_on__ imply __backend__Mike Bayer2020-12-191-0/+1
| | | | | | | | | | | | | | | | | | CI missed a few SQL Server tests because we run mssql-backendonly in the gerrit job. As there was a test that was "only on" mssql but didn't have backendonly, it never got run and then fails in master where we run mssql fully. Any suite that has an __only_on__ is inherently specific to a backend, so if present this should imply __backend__ so that it definitely runs when we have that backend present. This in turn meant we had to fix a few sqlite_file tests that weren't cleaning up or sharing well as they suddenly became backend tests under sqlite_file. Added a sqlite_file cleanup to test class cleanup for now. Change-Id: I9de1ceabd6596547a65c59059a55b7e5156103fd

| | | | | | | pytest has removed support for pytest.Class().collect() and we need to use from_parent. Change-Id: Ia5fed9b22e76c99f71489283acee207f996f52a4
* Add support for identity columnsFederico Caselli2020-08-191-7/+2
| | | | | | | | | | | | | | Added the :class:`_schema.Identity` construct that can be used to configure identity columns rendered with GENERATED { ALWAYS | BY DEFAULT } AS IDENTITY. Currently the supported backends are PostgreSQL >= 10, Oracle >= 12 and MSSQL (with different syntax and a subset of functionalities).

* Provision on different drivers dynamicallyMike Bayer2020-08-142-10/+31
| | | | | | | | | | | We want TOX_POSTGRESQL and similar to be the fixed variable that is configured from CI environment. These variables should refer to database servers but individual drivers like asyncpg mysqlconnector etc. should come from local tox.ini. add a new system to generate per-driver URLs from a simple list of hostname-based URLs delivered from CI environment.

* Implement rudimentary asyncio support w/ asyncpgMike Bayer2020-08-132-2/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | Using the approach introduced at https://gist.github.com/zzzeek/6287e28054d3baddc07fa21a7227904e We can now create asyncio endpoints that are then handled in "implicit IO" form within the majority of the Core internals. Then coroutines are re-exposed at the point at which we call into asyncpg methods. Patch includes: * asyncpg dialect * asyncio package * engine, result, ORM session classes * new test fixtures, tests * some work with pep-484 and a short plugin for the pyannotate package, which seems to have so-so results Change-Id: Idbcc0eff72c4cad572914acdd6f40ddb1aef1a7d Fixes: #3414

* Add support for "real" sequences in mssqlGord Thompson2020-05-291-0/+2
| | | | | | | | | | | | | | | | | Added support for "CREATE SEQUENCE" and full :class:`.Sequence` support for Microsoft SQL Server. This removes the deprecated feature of using :class:`.Sequence` objects to manipulate IDENTITY characteristics which should now be performed using ``mssql_identity_start`` and ``mssql_identity_increment`` as documented at :ref:`mssql_identity`. The change includes a new parameter :paramref:`.Sequence.data_type` to accommodate SQL Server's choice of datatype, which for that backend includes INTEGER and BIGINT. The default starting value for SQL Server's version of :class:`.Sequence` has been set at 1; this default is now emitted within the CREATE SEQUENCE DDL for all backends.

* Update transaction / connection handlingMike Bayer2020-05-171-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | step one, do away with __connection attribute and using awkward AttributeError logic step two, move all management of "connection._transaction" into the transaction objects themselves where it's easier to follow. build MarkerTransaction that takes the role of "do-nothing block" new connection datamodel is: connection._transaction, always a root, connection._nested_transaction, always a nested. nested transactions still chain to each other as this is still sort of necessary but they consider the root transaction separately, and the marker transactions not at all. introduce new InvalidRequestError subclass PendingRollbackError. Apply to connection and session for all cases where a transaction needs to be rolled back before continuing. Within Connection, both PendingRollbackError as well as ResourceClosedError are now raised directly without being handled by handle_dbapi_error(); this removes these two exception cases from the handle_error event handler as well as from StatementError wrapping, as these two exceptions are not statement oriented and are instead programmatic issues, that the application is failing to handle database errors properly. Revise savepoints so that when a release fails, they set themselves as inactive so that their rollback() method does not throw another exception. Give savepoints another go on MySQL, can't get release working however get support for basic round trip going Fixes: #5327 Change-Id: Ia3cbbf56d4882fcc7980f90519412f1711fae74d

* Dont raise on pytest deprecation warningsMike Bayer2020-03-121-0/+13
| | | | | | | | | py.test 5.4.0 emits deprecation warnings for pytest.Class. make sure we don't raise for these, and log the code that will be used for 5.4.0 when we bump requirements. Fixes: #5201 Change-Id: I83e0402c4a6b2365a63b58d052c6989df3a37328
* Rework combination exclusionsMike Bayer2020-02-101-41/+123
| | | | | | | | | | | | | | | | | | | | | | | | | The technique arrived at for doing exclusions inside of combinations relies upon comparing all the arguments in a particular combination to some set of combinations that were gathered as having "exclusions". This logic is actually broken for the case where the @testing.combinations has an "id", but if we fix that, we still have the issue of all the arguments being compared, which is complicated and also doesn't work for the case of a py2/py3 incompatibility like a timezone that has fractional minutes or seconds in it. It's also not clear if a @testing.combinations that uses lambdas will work either (maybe it does though because lambdax == lambdax compares...). anyway, this patch reworks it so that we hit this on the decorator side instead, where we add our own decorator and go through the extra effort to create a decorator that accepts an extra argument of "exclusions" which we can then check in a way that is local to the whole pytest @combinations thing in the first place. The only difficulty is that pytest is very sneaky about looking at the test function so we need to make sure __wrapped__ isn't set when doing this.

* Introduce lambda combinationsMike Bayer2019-12-041-2/+10
| | | | | | | | | | | | As the ORM's combinatoric tests mostly use entities and table metadata that's defined in fixtures, we can't use @testing.combinations directly as it takes place at the module level. Instead we use lambdas, but to reduce verbosity we use a code replacement so that the namespace of the lambda can be provided at runtime rather than module import time.

* Test fixture improvementsMike Bayer2019-11-112-0/+6
| | | | | | | | | | - ensure we escape out percent signs when a CompiledSQL or RegexSQL has percent signs in the SQL or in the parameter repr - to support combinations, print out complete test name in skip messages, py.test environment gives us a way to do this Change-Id: Ia9e62f7c1026c1465986144c5757e35fc164a2b8
* Support exclusion rules in combinationsMike Bayer2019-11-091-2/+32
| | | | | | | | | | | Like py.test we need to be able to mark certain combination elements with exclusion rules. Add additional logic to pytestlplugin and exclusions so that the exclusion decorators can be added to the combination tuples, where they will be applied to the decorated function along with a qualifier that the test arguments need to match what's given.

* Refactor dialect tests for combinationsMike Bayer2019-10-222-3/+3
| | | | | | | | | | | | | | Dialect tests tend to have a lot of lists of types, SQL constructs etc, convert as many of these to @combinations as possible. This is exposing that we don't have per-combination exclusion rules set up which is making things a little bit cumbersome. Also set up a fixture that does metadata + DDL.
