[Sqlalchemy-commits] commit/sqlalchemy: zzzeek: Allow SchemaType and Variant to work together

[Bitbucket <com...@bi...>]

1 new commit in sqlalchemy:

https://bitbucket.org/zzzeek/sqlalchemy/commits/c04870ba7b80/
Changeset:   c04870ba7b80
Branch:      master
User:        zzzeek
Date:        2017-03-07 21:24:18+00:00
Summary:     Allow SchemaType and Variant to work together

Added support for the :class:`.Variant` and the :class:`.SchemaType`
objects to be compatible with each other.  That is, a variant
can be created against a type like :class:`.Enum`, and the instructions
to create constraints and/or database-specific type objects will
propagate correctly as per the variant's dialect mapping.

Also added testing for some potential double-event scenarios
on TypeDecorator but it seems usually this doesn't occur.

https://bitbucket.org/zzzeek/sqlalchemy/commits/f4c4f784cde8/
Changeset:   f4c4f784cde8
Branch:      None
User:        zzzeek
Date:        2017-03-06 22:20:06+00:00
Summary:     Don't cache savepoint identifiers

Fixed bug in compiler where the string identifier of a savepoint would
be cached in the identifier quoting dictionary; as these identifiers
are arbitrary, a small memory leak could occur if a single
:class:`.Connection` had an unbounded number of savepoints used,
as well as if the savepoint clause constructs were used directly
with an unbounded umber of savepoint names.   The memory leak does
**not** impact the vast majority of cases as normally the
:class:`.Connection`, which renders savepoint names with a simple
counter starting at "1", is used on a per-transaction or
per-fixed-number-of-transactions basis before being discarded.

The savepoint name in virtually all cases does not require quoting
at all, however to support potential third party use cases
the "check for quotes needed" logic is retained, at a small
performance cost.   Uncondtionally quoting the name is another
option, but this would turn the name into a case sensitive name
which runs the risk of poor interactions with existing deployments
that may be looking at these names in other contexts.

Summary:     Only use schema_translate_map on SchemaItem subclasses

Fixed bug in new "schema translate" feature where the translated schema
name would be invoked in terms of an alias name when rendered along
with a column expression; occurred only when the source translate
name was "None".   The "schema translate" feature now only takes
effect for :class:`.SchemaItem` and :class:`.SchemaType` subclasses,
that is, objects that correspond to a DDL-creatable structure in
a database.

[Sqlalchemy-commits] commit/sqlalchemy: zzzeek: Performance within instances()

Summary:     Performance within instances()

Continuing from Ie43beecf37945b2bb7fff0aaa597a597293daa18,
also observed is the overhead of PathRegsitry memoized token
functions, as these paths are not cached in the case of
long joinedloader chains.  The memoizations here were made
with short paths in mind, and have been replaced with
an inlined straight create of these paths up front, producing
callcounts very similar to 0.8. Combined with the previous
optimizations, 1.1 now runs the "joined eager load of one row"
worst case test in about 40% fewer calls than 0.8 and 60%
fewer than 1.1.5.

Summary:     Memoize AliasedClass, ClauseAdapter objects in joined eager load

Addressed some long unattended performance concerns within the
joined eager loader query construction system.  The use of ad-hoc
:class:`.AliasedClass` objects per query, which produces lots of column
lookup overhead each time, has been replaced with a cached approach
that makes use of a small pool of :class:`.AliasedClass` objects
that are reused between invocations of joined eager loading.
Callcount reduction of SQL query generation for worst-case joined
loader scenarios (lots of joins, lots of columns) is reduced by
approximately 270%.

[Sqlalchemy-commits] commit/sqlalchemy: zzzeek: Check for columns not part of mapping, correct mapping for eager_defaults

Summary:     Check for columns not part of mapping, correct mapping for eager_defaults

Fixed two closely related bugs involving the mapper eager_defaults
flag in conjunction with single-table inheritance; one where the
eager defaults logic would inadvertently try to access a column
that's part of the mapper's "exclude_properties" list (used by
Declarative with single table inheritance) during the eager defaults
fetch, and the other where the full load of the row in order to
fetch the defaults would fail to use the correct inheriting mapper.

Summary:     Don't post-SELECT columns w/o a server default/onupdate for eager_defaults

Fixed a major inefficiency in the "eager_defaults" feature whereby
an unnecessary SELECT would be emitted for column values where the
ORM had explicitly inserted NULL, corresponding to attributes that
were unset on the object but did not have any server default
specified, as well as expired attributes on update that nevertheless
had no server onupdate set up.   As these columns are not part of the
RETURNING that eager_defaults tries to use, they should not be
post-SELECTed either.

[Sqlalchemy-commits] commit/sqlalchemy: 2 new changesets

[Bitbucket <com...@bi...>]

2 new commits in sqlalchemy:

https://bitbucket.org/zzzeek/sqlalchemy/commits/388d8db68d0d/
Changeset:   388d8db68d0d
Branch:      None
User:        zzzeek
Date:        2017-02-01 22:00:42+00:00
Summary:     Accept FetchedValue, text() for column "default" value

Fixed bug whereby the :meth:`.DDLEvents.column_reflect` event would not
allow a non-textual expression to be passed as the value of the
"default" for the new column, such as a :class:`.FetchedValue`
object to indicate a generic triggered default or a
:func:`.sql.expression.text` construct.  Clarified the documentation
in this regard as well.

Fixes: #3905
