| * Add a third labeling mode for SELECT statementsMike Bayer2020-03-291-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enhanced the disambiguating labels feature of the :func:`~.sql.expression.select` construct such that when a select statement is used in a subquery, repeated column names from different tables are now automatically labeled with a unique label name, without the need to use the full "apply_labels()" feature that conbines tablename plus column name. The disambigated labels are available as plain string keys in the .c collection of the subquery, and most importantly the feature allows an ORM :func:`.orm.aliased` construct against the combination of an entity and an arbitrary subquery to work correctly, targeting the correct columns despite same-named columns in the source tables, without the need for an "apply labels" warning. The existing labeling style is now called LABEL_STYLE_TABLENAME_PLUS_COL. This labeling style will remain used throughout the ORM as has been the case for over a decade, however, the new disambiguation scheme could theoretically replace this scheme entirely. The new scheme would dramatically alter how SQL looks when rendered from the ORM to be more succinct but arguably harder to read. The tablename_columnname scheme used by Join.c is unaffected here, as that's still hardcoded to that scheme. Fixes: #5221 Change-Id: Ib47d9e0f35046b3afc77bef6e65709b93d0c3026

| * Convert schema_translate to a post compileMike Bayer2020-03-243-8/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Revised the :paramref:`.Connection.execution_options.schema_translate_map` feature such that the processing of the SQL statement to receive a specific schema name occurs within the execution phase of the statement, rather than at the compile phase. This is to support the statement being efficiently cached. Previously, the current schema being rendered into the statement for a particular run would be considered as part of the cache key itself, meaning that for a run against hundreds of schemas, there would be hundreds of cache keys, rendering the cache much less performant. The new behavior is that the rendering is done in a similar manner as the "post compile" rendering added in 1.4 as part of :ticket:`4645`, :ticket:`4808`.

* | Implement autocommit isolation level for cx_oracleGord Thompson2020-03-232-1/+92
|/ | | | | | | | | | | | | | | | As part of this change Oracle also gets the concept of a default isolation level, however since Oracle does not provide a fixed method of knowing what the isolation level would be without a server side transaction actually in progress, for now we hardcode just to "READ COMMITTED". Enhanced the test suite for isolation level testing in the dialect test suite and added features to requirements so that the supported isolation levels can be reported generically for dialects.

The previous issue with this was that they would produce dupe labels in SELECT statements. Apply the duplicate column logic, newly added in 1.4, to these objects as well as to non-apply-labels SELECT statements in general as a means of improving this. - create a revised system for generating ClauseList compilation constructs that simplfies up front creation to not actually use ClauseList; a simple tuple is rendered by the compiler using the same constrcution rules as what are used for ClauseList but without creating the actual object. Apply to Select, CompoundSelect, revise Update, Delete - Select, CompoundSelect get an initial CompileState implementation. All methods used only within compilation are moved here - refine update/insert/delete compile state to not require an outside boolean - refine and simplify Select._copy_internals - rework bind(), which is going away, to not use some of the internal traversal stuff - remove "autocommit", "for_update" parameters from Select, references #4643 - remove "autocommit" parameter from TextClause , references #4643 - add deprecation warnings for statement.execute(), engine.execute(), statement.scalar(), engine.scalar().

* | Don't import provision.py unconditionallyMike Bayer2020-03-032-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Removed the imports for provision.py from each dialect and instead added a call in the central provision.py to a new dialect level method load_provisioning(). The provisioning registry works in the same way, so an existing dialect that is using the provision.py system right now by importing it as part of the package will still continue to function. However, to avoid pulling in the testing package when the dialect is used in a non-testing context, the new hook may be used. Also removed a module-level dependency of the testing framework on the orm package. Revised an internal change to the test system added as a result of :ticket:`5085` where a testing-related module per dialect would be loaded unconditionally upon making use of that dialect, pulling in SQLAlchemy's testing framework as well as the ORM into the module import space. This would only impact initial startup time and memory to a modest extent, however it's best that these additional modules aren't reverse-dependent on straight Core usage.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | Applied an explicit "cause" to most if not all internally raised exceptions that are raised from within an internal exception catch, to avoid misleading stacktraces that suggest an error within the handling of an exception. While it would be preferable to suppress the internally caught exception in the way that the ``__suppress_context__`` attribute would, there does not as yet seem to be a way to do this without suppressing an enclosing user constructed context, so for now it exposes the internally caught exception as the cause so that full information about the context of the error is maintained.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This builds on cc718cccc0bf8a01abdf4068c7ea4f3 which moved RowProxy to Row, allowing Row to be more like a named tuple. - KeyedTuple in ORM is replaced with Row - ResultSetMetaData broken out into "simple" and "cursor" versions for ORM and Core, as well as LegacyCursor version. - Row now has _mapping attribute that supplies full mapping behavior. Row and SimpleRow both have named tuple behavior otherwise. LegacyRow has some mapping features on the tuple which emit deprecation warnings (e.g. keys(), values(), etc). the biggest change for mapping->tuple is the behavior of __contains__ which moves from testing of "key in row" to "value in row". - ResultProxy breaks into ResultProxy and FutureResult (interim), the latter has the newer APIs. Made available to dialects using execution options. - internal reflection methods and most tests move off of implicit Row mapping behavior and move to row._mapping, result.mappings() method using future result - a new strategy system for cursor handling replaces the various subclasses of RowProxy - some execution context adjustments. We will leave EC in but refined things like get_result_proxy() and out parameter handling. Dialects for 1.4 will need to adjust from get_result_proxy() to get_result_cursor_strategy(), if they are using this method - out parameter handling now accommodated by get_out_parameter_values() EC method. Oracle changes for this. external dialect for DB2 for example will also need to adjust for this. - deprecate case_insensitive flag for engine / result, this feature is not used mapping-methods on Row are deprecated, and replaced with Row._mapping.<meth>, including: row.keys() -> use row._mapping.keys() row.items() -> use row._mapping.items() row.values() -> use row._mapping.values() key in row -> use key in row._mapping int in row -> use int < len(row) Fixes: #4710 Fixes: #4878 Change-Id: Ieb9085e9bcff564359095b754da9ae0af55679f0
* Deprecate connection branchingMike Bayer2020-02-213-2/+6
| | | | | | | | | | | | | | | The :meth:`.Connection.connect` method is deprecated as is the concept of "connection branching", which copies a :class:`.Connection` into a new one that has a no-op ".close()" method. This pattern is oriented around the "connectionless execution" concept which is also being removed in 2.0. As part of this change we begin to move the internals away from "connectionless execution" overall.

|/ | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * apply asbool reduction to the onclause in join()Mike Bayer2020-01-171-0/+102
| | | | | | | | | | | | | | | | | | | | The :func:`.true` and :func:`.false` operators may now be applied as the "onclause" of a :func:`.sql.join` on a backend that does not support "native boolean" expressions, e.g. Oracle or SQL Server, and the expression will render as "1=1" for true and "1=0" false. This is the behavior that was introduced many years ago in :ticket:`2804` for and/or expressions. Change-Id: I85311c31c22d6e226c618f8840f6b95eca611153
* | Remove jython code, remove all jython / pypy symbolsMike Bayer2020-01-175-31/+13
|/ | | | | | | | | | | | | | | | | | | | | | Removed all dialect code related to support for Jython and zxJDBC. Jython has not been supported by SQLAlchemy for many years and it is not expected that the current zxJDBC code is at all functional; for the moment it just takes up space and adds confusion by showing up in documentation. At the moment, it appears that Jython has achieved Python 2.7 support in its releases but not Python 3. If Jython were to be supported again, the form it should take is against the Python 3 version of Jython, and the various zxJDBC stubs for various backends should be implemented as a third party dialect. Additionally modernized logic that distinguishes between "cpython" and "pypy" to instead look at platform.python_distribution() which reliably tells us if we are cPython or not; all booleans which previously checked for pypy and sometimes jython are now converted to be "not cpython", this impacts the test suite for tests that are cPython centric.
