upgrade to black 20.8b1

2020-09-28T19:17:26+00:00

It's better, the majority of these changes look more readable to me.
also found some docstrings that had formatting / quoting issues.

Pass all pool parameters in recreate()

2020-09-14T15:36:31+00:00

The following pool parameters were not being propagated to the new pool
created when :meth:`_engine.Engine.dispose` were called: ``pre_ping``,
``use_lifo``.  Additionally the ``recycle`` and ``reset_on_return``
parameters were not propagated for the :class:`_engine.AssertionPool`
class.  These issues have been fixed.

Fixes: #5582

Fix AsyncEngine connect() bug when pool is exhausted

2020-08-31T07:41:00+00:00

### Description

Decorating the referenced `await_fallback` with `staticmethod` would stop `AsyncAdaptedQueue.await_` from being treated as a bound method.

Implement rudimentary asyncio support w/ asyncpg

2020-08-13T22:41:53+00:00

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

Merge "Use context managers for threading.Lock()"

2020-01-03T21:49:49+00:00

Use context managers for threading.Lock()

2020-01-03T18:09:46+00:00

(zzzeek:) For some reason I thought that threading.Lock() still did
not support context managers, at least in Python 2, however this
does not seem to be the case.

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.
