the python 3 merge, now does not expect percent signs (e.g.
as used as the modulus operator and others) to be doubled,
even when using the "pyformat" bound parameter format (this
change is not documented by Mysqlconnector). The dialect now
checks for py2k and for mysqlconnector less than version 2.0
when detecting if the modulus operator should be rendered as
``%%`` or ``%``.
- Unicode SQL is now passed for MySQLconnector version 2.0 and above;
for Py2k and MySQL < 2.0, strings are encoded. Note that mysqlconnector
as of 2.0.1 appears to have a bug with unicode DDL on py2k, so the tests here
are skipping until we observe it's fixed.
- take out profiling on mysqlconnector, callcounts vary too much with
its current development speed
seems to be used by test_oracle->test_coerce_to_unicode(). The
predicate here should treat as a lambda based on enabled_for_config.
not sure why this test is not failing on jenkins
defaults if otherwise unspecified; the limitation where non-
server column defaults aren't included in an INSERT FROM
SELECT is now lifted and these expressions are rendered as
constants into the SELECT statement.
:meth:`.Query.outerjoin`, or the standalone :func:`.orm.join` /
:func:`.orm.outerjoin` functions to a single-inheritance subclass will
now include the "single table criteria" in the ON clause even
if the ON clause is otherwise hand-rolled; it is now added to the
criteria using AND, the same way as if joining to a single-table
target using relationship or similar.

the sql package would fail to ``__repr__()`` successfully,
due to a missing ``description`` attribute that would then invoke
a recursion overflow when an internal AttributeError would then
re-invoke ``__repr__()``.
fixes#3195
:paramref:`.create_engine.execution_options` or
:meth:`.Engine.update_execution_options` are not passed to the
special :class:`.Connection` used to initialize the dialect
within the "first connect" event; dialects will usually
perform their own queries in this phase, and none of the
current available options should be applied here. In
particular, the "autocommit" option was causing an attempt to
autocommit within this initial connect which would fail with
an AttributeError due to the non-standard state of the
:class:`.Connection`.
fixes#3200
- add a test for PG reflection of unique index without any unique
constraint
- for PG, don't include 'duplicates_constraint' in the entry
if the index does not actually mirror a constraint
- use a distinct method for unique constraint reflection within table
- catch unique constraint not implemented condition; this may
be within some dialects and also is expected to be supported by
Alembic tests
- migration + changelogs for #3184
- add individual doc notes as well to MySQL, Postgreql

- When selecting from a UNION using an attached database file,
the pysqlite driver reports column names in cursor.description
as 'dbname.tablename.colname', instead of 'tablename.colname' as
it normally does for a UNION (note that it's supposed to just be
'colname' for both, but we work around it). The column translation
logic here has been adjusted to retrieve the rightmost token, rather
than the second token, so it works in both cases. Workaround

psycopg2's ``.closed`` accessor is not as reliable as we assumed,
so we have added an explicit check for the exception messages
"SSL SYSCALL error: Bad file descriptor" and
"SSL SYSCALL error: EOF detected" when detecting an
is-disconnect scenario. We will continue to consult psycopg2's
connection.closed as a first check.

when you call :meth:`.Connection.connect`, would not share transaction

a bit so that the branched connection defers to the parent for
all transactional status and operations.

- declarative now creates column copies ahead of time
so that they are ready to go for a declared_attr
- overhaul of declared_attr; memoization, cascading modifier
- A relationship set up with :class:`.declared_attr` on
a :class:`.AbstractConcreteBase` base class will now be configured
on the abstract base mapping automatically, in addition to being
set up on descendant concrete classes as usual.
fixes#2670
- The :class:`.declared_attr` construct has newly improved
behaviors and features in conjunction with declarative. The
decorated function will now have access to the final column
copies present on the local mixin when invoked, and will also
be invoked exactly once for each mapped class, the returned result
being memoized. A new modifier :attr:`.declared_attr.cascading`
is added as well. fixes#3150
- the original plan for #3150 has been scaled back; by copying
mixin columns up front and memoizing, we don't actually need
the "map properties later" thing.
- full docs + migration notes
``cascade="all, delete-orphan"`` automatically on a one-to-many
relationship/backref where the foreign key is detected as containing
one or more non-nullable columns. This argument is present in the
keywords passed to :func:`.automap.generate_relationship` in this
case and can still be overridden. Additionally, if the
:class:`.ForeignKeyConstraint` specifies ``ondelete="CASCADE"``
for a non-nullable or ``ondelete="SET NULL"`` for a nullable set
of columns, the argument ``passive_deletes=True`` is also added to the
relationship. Note that not all backends support reflection of
ondelete, but backends that do include Postgresql and MySQL.
fixes#3210
we need to be in transactions (tested elsewhere) and we need to
emit the correct FOR UPDATE strings (tested elsewhere). There's nothing
in SQLA to be tested as far as validating that for update causes exceptions
or not, and these tests frequently fail as they are timing sensitive.
as that of 🎫`3199`, when the ``named=True`` parameter
would be used. Some events would fail to register, and others
would not invoke the event arguments correctly, generally in the
case of when an event was "wrapped" for adaption in some other way.
The "named" mechanics have been rearranged to not interfere with
the argument signature expected by internal wrapper functions.
fixes#3197
setups, where the attempt to check for "duplicate class name" in
declarative would hit upon a not-totally-cleaned-up weak reference
related to some other class being removed; the check here now ensures
the weakref still references an object before calling upon it further.
