Use config.db global opts as defaults for all testing_engine()

2017-03-22T14:13:15+00:00

Some options need to be passed to engines in all cases,
such as currently the oracle 12516 workaround.   make sure
calls to testing_engine also set up the dictionary with
defaults even if options is passed.    not clear if this affects
other backends yet.

Integrate "pre-ping" into connection pool.

2017-03-20T22:01:23+00:00

Added native "pessimistic disconnection" handling to the :class:`.Pool`
object.  The new parameter :paramref:`.Pool.pre_ping`, available from
the engine as :paramref:`.create_engine.pool_pre_ping`, applies an
efficient form of the "pre-ping" recipe featured in the pooling
documentation, which upon each connection check out, emits a simple
statement, typically "SELECT 1", to test the connection for liveness.
If the existing connection is no longer able to respond to commands,
the connection is transparently recycled, and all other connections
made prior to the current timestamp are invalidated.

- repair that we use db_opts when the url here is different,

2015-06-19T23:24:10+00:00

as we are using db_opts for the first time with legacy_schema_args

- repair a regression caused by #3282, where we no longer were

applying any topological sort to tables on SQLite.  See the
changelog for details, but we now continue to sort
tables for SQLite on DROP, prohibit the sort from considering
alter, and only warn if we encounter an unresolvable cycle, in
which case, then we forego the ordering.  use_alter as always
is used to break such a cycle.
fixes #3378

- force the _has_events flag to True on engines, so that

profiling is more predictable
- restore the profiling from before this change

- rework the assert_sql system so that we have a context manager to work with,

use events that are local to the engine and to the run and are removed afterwards.
