Don't emit pyodbc "no driver" warning for empty URL

2020-05-22T17:15:30+00:00

Fixed an issue in the pyodbc connector such that a warning about pyodbc
"drivername" would be emitted when using a totally empty URL.  Empty URLs
are normal when producing a non-connected dialect object or when using the
"creator" argument to create_engine(). The warning now only emits if the
driver name is missing but other parameters are still present.

Remove jython code, remove all jython / pypy symbols

2020-01-17T22:44:57+00:00

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.

Post black reformatting

2019-01-06T23:23:11+00:00

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.

Run black -l 79 against all source files

2019-01-06T17:34:50+00:00

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.
