Rudimentary and experimental support for Mypy has been added in the form of
a new plugin, which itself depends on new typing stubs for SQLAlchemy. The
plugin allows declarative mappings in their standard form to both be
compatible with Mypy as well as to provide typing support for mapped
classes and instances.
Fixes: #4609

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.

This WIP is part of the final push for 1.4's docs
to fully "2.0-ize" what we can, and have it all ready.
So far this includes a rewrite of the 2.0 migration,
set up for the 1.4 /2.0 docs style, and a total redesign
of the index page using a new flex layout in zzzeeksphinx.
It also reworks some of the API reference sections
to have more subheaders. zzzeeksphinx is also enhanced
to provide automatic summaries for all api doc section.

Two operations have been defined:
* :meth:`~.ColumnOperators.regexp_match` implementing a regular
expression match like function.
* :meth:`~.ColumnOperators.regexp_replace` implementing a regular
expression string replace function.

it's not really correct that URL is mutable and doesn't do
any argument checking. propose replacing it with an immutable
named tuple with rich copy-and-mutate methods.
At the moment this makes a hard change to the CreateEnginePlugin
docs that previously recommended url.query.pop(). I can't find
any plugins on github other than my own that are using this
feature, so see if we can just make a hard change on this one.

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

* major additions to 1.4 migration doc; removed additional
verbosity regarding caching methodology and reorganized the
doc to present itself more as a "what's changed" guide
* as we now have a path for asyncio, update that doc so that
we aren't spreading obsolete information
* updates to the 2.0 migration guide with latest info, however
this is still an architecture doc and not a migration guide
yet, will need further rework.
* start really talking about 1.x vs. 2.0 style everywhere. Querying
is most of the docs so this is going to be a prominent
theme, start getting it to fit in
* Add introductory documentation for ORM example sections as these
are too sparse
* new documentation for do_orm_execute(), many separate sections,
adding deprecation notes to before_compile() and similar
* new example suites to illustrate do_orm_execute(),
with_loader_criteria()
* modernized horizontal sharding examples and added a separate
example to distinguish between multiple databases and single
database w/ multiple tables use case
* introducing DEEP ALCHEMY, will use zzzeeksphinx 1.1.6
* no name for the alchemist yet however the dragon's name
is Flambé

Renamed the :meth:`_schema.Table.tometadata` method to
:meth:`_schema.Table.to_metadata`. The previous name remains with a
deprecation warning.
Updated the "decorate" utility function to support decoration
of functions that include non-builtins as default values.
Moves test for deprecated "databases" package into
test/dialect/test_deprecations.py

The psycopg2 dialect now defaults to using the very performant
``execute_values()`` psycopg2 extension for compiled INSERT statements,
and also impements RETURNING support when this extension is used. This
allows INSERT statements that even include an autoincremented SERIAL
or IDENTITY value to run very fast while still being able to return the
newly generated primary key values. The ORM will then integrate this
new feature in a separate change.
Implements RETURNING for insert with executemany
Adds support to return_defaults() mode and inserted_primary_key
to support mutiple INSERTed rows, via return_defauls_rows
and inserted_primary_key_rows accessors.
within default execution context, new cached compiler
getters are used to fetch primary keys from rows
inserted_primary_key now returns a plain tuple. this
is not yet a row-like object however this can be
added.
Adds distinct "values_only" and "batch" modes, as
"values" has a lot of benefits but "batch" breaks
cursor.rowcount
psycopg2 minimum version 2.7 so we can remove the
large number of checks for very old versions of
psycopg2
simplify tests to no longer distinguish between
native and non-native json

Convert Query to do virtually all compile state computation
in the _compile_context() phase, and organize it all
such that a plain select() construct may also be used as the
source of information in order to generate ORM query state.
This makes it such that Query is not needed except for
its additional methods like from_self() which are all to
be deprecated.
The construction of ORM state will occur beyond the
caching boundary when the new execution model is integrated.
future select() gains a working join() and filter_by() method.
as we continue to rebase and merge each commit in the steps,
callcounts continue to bump around. will have to look at
the final result when it's all in.

SQLite supports CTEs as do both the MariaDB and MySQL
databases now. Expand test support and begin adding
new tutorial sections to make this concept more prominent.
Also fix some formatting issues in the tutorial, and start
moving more towards {opensql} - the "SQL" button thing
is cool but the tutorials mainly need to illustrate how
the SQL looks for things. Screens are bigger now and
we likely should move away from the SQL button almost
entirely.
CTE for the tutorial needed zzzeeksphinx fix to recognize
"WITH" so bumping that to latest release number in git.

For a 1.4 / 1.3 merge, rewrite the documentation for
Query.join() to indicate calling forms that are now considered
legacy, including the use of strings in join(), sending a
series of join paths in one call, and using the aliased=True
flag. update the elementtree examples as well to use aliased()
(they are much simpler to understand this way too) and update
other links.
Also improve docs for aliased() and some other ORM targets
such as PropComparator.
