Included are resolutions for all remaining flake8 issues including shadowed builtins, long lines, import order, unused imports, duplicate imports, and docstring issues.

resolves all remaining flake8 conditions for those codes

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.

Use identity_token for refresh(), unexpire, undefer 2018-05-11T14:41:02+00:00 Mike Bayer mike_mp@zzzcomputing.com 2018-05-03T16:35:23+00:00 a7eaa6afc818e495987f6ecb39d122ff32430c03 The horizontal sharding extension now makes use of the identity token added to ORM identity keys as part of :ticket:`4137`, when an object refresh or column-based deferred load or unexpiration operation occurs. Since we know the "shard" that the object originated from, we make use of this value when refreshing, thereby avoiding queries against other shards that don't match this object's identity in any case.

Refactor "get" to allow for pluggable identity token schemes 2018-04-20T19:10:04+00:00 Mike Bayer mike_mp@zzzcomputing.com 2018-04-20T15:44:09+00:00 eee88f5fb5fb5cda1f92a6c7a8d27a57cfd86e71 Fixed regression in 1.2 within sharded query feature where the new "identity_token" element was not being correctly considered within the scope of a lazy load operation, when searching the identity map for a related many-to-one element. The new behavior will allow for making use of the "id_chooser" in order to determine the best identity key to retrieve from the identity map. In order to achieve this, some refactoring of 1.2's "identity_token" approach has made some slight changes to the implementation of ``ShardedQuery`` which should be noted for other derivations of this class.
