tutorial 2.0 WIP

2020-10-31T17:44:53+00:00

Add SelectBase.exists() method as it seems strange this is
not available already.  The Exists construct itself does
not provide full SELECT-building capabilities so it makes
sense this should be used more like a scalar_subquery.

Make sure stream_results is getting set up when yield_per
is used, for 2.0 style statements as well.  this was
hardcoded inside of Query.yield_per() and is now moved
to take place within QueryContext.

Add deprecation for base Executable.bind

2020-10-16T23:15:58+00:00

These attributes will be removed in SQLAlchemy 2.0.

Also alters the deprecation message to qualify the
type of object correctly.  this in turn requires changes
in the warnings filter and deprecation tests.

Merge "Drop python 3.5 support"

generalize scoped_session proxying and apply to asyncio elements

2020-10-10T05:17:25+00:00

Reworked the proxy creation used by scoped_session() to be
based on fully copied code with augmented docstrings and
moved it into langhelpers.  asyncio session, engine,
connection can now take
advantage of it so that all non-async methods are availble.

Overall implementation of most important accessors / methods
on AsyncConnection, etc. , including awaitable versions
of invalidate, execution_options, etc.

In order to support an event dispatcher on the async
classes while still allowing them to hold __slots__,
make some adjustments to the event system to allow
that to be present, at least rudimentally.

Revert "Use monotonic time for pool age measurement"

2020-10-07T14:09:41+00:00

This reverts commit 0220b58917b5a979891b5765f6ac5095e0368489.

I completely misread https://www.python.org/dev/peps/pep-0418/#rationale
and the accuracy of monotonic() is *worse* on windows than time.time(),
which is bizarre.

Use monotonic time for pool age measurement

2020-10-07T13:14:13+00:00

The internal clock used by the :class:`_pool.Pool` object is now
time.monotonic_time() under Python 3.  Under Python 2, time.time() is still
used, which is legacy. This clock is used to measure the age of a
connection against its starttime, and used in comparisons against the
pool_timeout setting as well as the last time the pool was marked as
invalid to determine if the connection should be recycled. Previously,
time.time() was used which was subject to inaccuracies as a result of
system clock changes as well as poor time resolution on windows.

Use preloaded for sql.util import in exc

2020-10-07T02:25:23+00:00

Repaired a function-level import that was not using SQLAlchemy's standard
late-import system within the sqlalchemy.exc module.

Moved preloaded to sqlalchemy.util.preloaded so that it
does not depend on langhelpers which depends on exc.
