* Remove jython code, remove all jython / pypy symbolsMike Bayer2020-01-171-7/+7
| | | | | | | | | | | | | | | | | | | | | | 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. Fixes: #5094 Change-Id: I226cb55827f997daf6b4f4a755c18e7f4eb8d9ad
* Fix cext for Python 2; ensure C extensions build successfullyMike Bayer2020-01-041-10/+13
| | | | | | | | | | | | | | | | | | | | The C extensions have been broken since cc718cccc0bf8a01abdf4068c however CI did not find this, because the build degraded to non-C extensions without failing. Ensure that if cext is set, there is no fallback to non-cext build if the C extension build fails. Repair C related issues introduced in cc718cccc0bf8a01abdf4068c. As C extensions have been silently failing on 2.7 for some commits, the callcounts also needed to be adjusted for recent performance-related changes. That in turn required a fix to the profiling decorator to use signature rewriting in order to support py.test's fixture mechanism under Python 2, usage introduced under profiling in 89bf6d80a9. Fixes: #5076 Change-Id: Id968f10c85d6bf489298b1c318a1f869ad3e7d80

* Don't apply aliasing + adaption for simple relationship joinsMike Bayer2019-12-191-2/+5
| | | | | | | | | | | Identified a performance issue in the system by which a join is constructed based on a mapped relationship. The clause adaption system would be used for the majority of join expressions including in the common case where no adaptation is needed. The conditions under which this adaptation occur have been refined so that average non-aliased joins along a simple relationship without a "secondary" table use about 70% less function calls.

* Add profile sort option to test suiteMike Bayer2019-07-141-2/+3
| | | | | | | | I use the nfl sort a lot to see what calling changes are happening between two versions in order to identify the offending code, so add it as a command line option. Change-Id: Ia1ab6dd98012a78298b325bb5c7c050fa9b767c2
* profiling plugin fixesMike Bayer2019-07-111-6/+41

* Post black reformattingMike Bayer2019-01-061-5/+10
| | | | | | | | | | | | | Applied on top of a pure run of black -l 79 in I7eda77fed3d8e73df84b3651fd6cfcfe858d4dc9, this set of changes resolves all remaining flake8 conditions for those codes we have enabled in setup.cfg. Included are resolutions for all remaining flake8 issues including shadowed builtins, long lines, import order, unused imports, duplicate imports, and docstring issues. Change-Id: I4f72d3ba1380dd601610ff80b8fb06a2aff8b0fe
* Run black -l 79 against all source filesMike Bayer2019-01-061-36/+35
| | | | | | | | | | | | | | This is a straight reformat run using black as is, with no edits applied at all. The black run will format code consistently, however in some cases that are prevalent in SQLAlchemy code it produces too-long lines. The too-long lines will be resolved in the following commit that will resolve all remaining flake8 issues including shadowed builtins, long lines, import order, unused imports, duplicate imports, and docstring issues.

* Assorted pre-Black fixesMike Bayer2019-01-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes to the test suite, a few errant imports, and setup.py: - mysql and postgresql have unused 'json' imports; remove - postgresql is exporting the 'json' symbol, remove - make sure setup.py can find __version__ using " or ' - retry logic in provision create database for postgresql fixed - refactor test_magazine to use cls.tables rather than globals - remove unused class in test_scoping - add a comment to test_deprecations that this test suite itself is deprecated - don't use mapper() and orm_mapper() in test_unitofwork, just use mapper() - remove dupe test_scalar_set_None test in test_attributes - Python 2.7 and above includes unittest.SkipTest, remove pre-2.7 fallback - use imported SkipTest in profiling - declarative test_reflection tests with "reflectable_autoincrement" already don't run on oracle or firebird; remove conditional logic for these, which also removes an "id" symbol - clean up test in test_functions, remove print statement - remove dupe test_literal_processor_coercion_native_int_out_of_range in test/sql/test_types.py - fix psycopg2_hstore ref Change-Id: I7b3444f8546aac82be81cd1e7b6d8b2ad6834fe6

become an externally usable package but still remains within the main sqlalchemy parent package. in this system, we use kind of an ugly hack to get the noseplugin imported outside of the "sqlalchemy" package, while still making it available within sqlalchemy for usage by third party libraries.
