- update to version 1.3.11:
  * orm
    + [orm] [bug] The relationship.omit_join flag was not intended to
      be manually set to True, and will now emit a warning when this
      occurs. The omit_join optimization is detected automatically,
      and the omit_join flag was only intended to disable the
      optimization in the hypothetical case that the optimization may
      have interfered with correct results, which has not been
      observed with the modern version of this feature. Setting the
      flag to True when it is not automatically detected may cause the
      selectin load feature to not work correctly when a non-default
      primary join condition is in use.  References: #4954
    + [orm] [bug] A warning is emitted if a primary key value is
      passed to Query.get() that consists of None for all primary key
      column positions. Previously, passing a single None outside of a
      tuple would raise a TypeError and passing a composite None
      (tuple of None values) would silently pass through. The fix now
      coerces the single None into a tuple where it is handled
      consistently with the other None conditions. Thanks to Lev
      Izraelit for the help with this.  References: #4915
    + [orm] [bug] The BakedQuery will not cache a query that was
      modified by a QueryEvents.before_compile() event, so that
      compilation hooks that may be applying ad-hoc modifications to
      queries will take effect on each run. In particular this is
      helpful for events that modify queries used in lazy loading as
      well as eager loading such as “select in” loading. In order to
      re-enable caching for a query modified by this event, a new flag
      bake_ok is added; see Using the before_compile event for
      details.  A longer term plan to provide a new form of SQL
      caching should solve this kind of issue more comprehensively.
      References: #4947
    + [orm] [bug] Fixed ORM bug where a “secondary” table that
      referred to a selectable which in some way would refer to the
      local primary table would apply aliasing to both sides of the
      join condition when a relationship-related join, either via
      Query.join() or by joinedload(), were generated. The “local”
      side is now excluded.  References: #4974
    + [orm] [usecase] Added accessor Query.is_single_entity() to
      Query, which will indicate if the results returned by this Query
      will be a list of ORM entities, or a tuple of entities or column
      expressions. SQLAlchemy hopes to improve upon the behavior of
      single entity / tuples in future releases such that the behavior
      would be explicit up front, however this attribute should be
      helpful with the current behavior. Pull request courtesy Patrick
      Hayes.  References: #4934
  * engine
    + [engine] [bug] Fixed bug where parameter repr as used in logging
      and error reporting needs additional context in order to
      distinguish between a list of parameters for a single statement
      and a list of parameter lists, as the “list of lists” structure
      could also indicate a single parameter list where the first
      parameter itself is a list, such as for an array parameter. The
      engine/connection now passes in an additional boolean indicating
      how the parameters should be considered. The only SQLAlchemy
      backend that expects arrays as parameters is that of psycopg2
      which uses pyformat parameters, so this issue has not been too
      apparent, however as other drivers that use positional gain more
      features it is important that this be supported. It also
      eliminates the need for the parameter repr function to guess
      based on the parameter structure passed.  References: #4902
    + [engine] [bug] [postgresql] Fixed bug in Inspector where the
      cache key generation did not take into account arguments passed
      in the form of tuples, such as the tuple of view name styles to
      return for the PostgreSQL dialect. This would lead the inspector
      to cache too generally for a more specific set of criteria. The
      logic has been adjusted to include every keyword element in the
      cache, as every argument is expected to be appropriate for a
      cache else the caching decorator should be bypassed by the
      dialect.  References: #4955
  * sql
    + [sql] [bug] [py3k] Changed the repr() of the quoted_name
      construct to use regular string repr() under Python 3, rather
      than running it through “backslashreplace” escaping, which can
      be misleading.  References: #4931
    + [sql] [usecase] Added new accessors to expressions of type JSON
      to allow for specific datatype access and comparison, covering
      strings, integers, numeric, boolean elements. This revises the
      documented approach of CASTing to string when comparing values,
      instead adding specific functionality into the PostgreSQL,
      SQlite, MySQL dialects to reliably deliver these basic types in
      all cases.  See also: JSON, JSON.Comparator.as_string(),
      JSON.Comparator.as_boolean(), JSON.Comparator.as_float(),
      JSON.Comparator.as_integer(), References: #4276
    + [sql] [usecase] The text() construct now supports “unique” bound
      parameters, which will dynamically uniquify themselves on
      compilation thus allowing multiple text() constructs with the
      same bound parameter names to be combined together.  References:
  * schema
    + [schema] [bug] Fixed bug where a table that would have a column
      label overlap with a plain column name, such as “ AS
      foo_id” vs. “foo.foo_id”, would prematurely generate the ._label
      attribute for a column before this overlap could be detected due
      to the use of the index=True or unique=True flag on the column
      in conjunction with the default naming convention of
      "column_0_label". This would then lead to failures when ._label
      were used later to generate a bound parameter name, in
      particular those used by the ORM when generating the WHERE
      clause for an UPDATE statement. The issue has been fixed by
      using an alternate ._label accessor for DDL generation that does
      not affect the state of the Column. The accessor also bypasses
      the key-deduplication step as it is not necessary for DDL, the
      naming is now consistently "<tablename>_<columnname>" without
      any subsequent numeric symbols when used in DDL.  References:
    + [schema] [usecase] Added DDL support for “computed columns”;
      these are DDL column specifications for columns that have a
      server-computed value, either upon SELECT (known as “virtual”)
      or at the point of which they are INSERTed or UPDATEd (known as
      “stored”). Support is established for Postgresql, MySQL, Oracle
      SQL Server and Firebird. Thanks to Federico Caselli for lots of
      work on this one.  See also: Computed (GENERATED ALWAYS AS)
      Columns References: #4894
  * mysql
    + [mysql] [bug] Added “Connection was killed” message interpreted
      from the base pymysql.Error class in order to detect closed
      connection, based on reports that this message is arriving via a
      pymysql.InternalError() object which indicates pymysql is not
      handling it correctly.  References: #4945
  * mssql
    + [mssql] [bug] Fixed issue in MSSQL dialect where an
      expression-based OFFSET value in a SELECT would be rejected,
      even though the dialect can render this expression inside of a
      ROW NUMBER-oriented LIMIT/OFFSET construct.  References: #4973
    + [mssql] [bug] Fixed an issue in the Engine.table_names() method
      where it would feed the dialect’s default schema name back into
      the dialect level table function, which in the case of SQL
      Server would interpret it as a dot-tokenized schema name as
      viewed by the mssql dialect, which would cause the method to
      fail in the case where the database username actually had a dot
      inside of it. In 1.3, this method is still used by the
      MetaData.reflect() function so is a prominent codepath. In 1.4,
      which is the current master development branch, this issue
      doesn’t exist, both because MetaData.reflect() isn’t using this
      method nor does the method pass the default schema name
      explicitly. The fix nonetheless guards against the default
      server name value returned by the dialect from being interpreted
      as dot-tokenized name under any circumstances by wrapping it in
      quoted_name().  References: #4923
  * oracle
    + [oracle] [bug] [firebird] Modified the approach of “name
      normalization” for the Oracle and Firebird dialects, which
      converts from the UPPERCASE-as-case-insensitive convention of
      these dialects into lowercase-as-case-insensitive for
      SQLAlchemy, to not automatically apply the quoted_name construct
      to a name that matches itself under upper or lower case
      conversion, as is the case for many non-european characters. All
      names used within metadata structures are converted to
      quoted_name objects in any case; the change here would only
      affect the output of some inspection functions.  References:
    + [oracle] [bug] The sqltypes.NCHAR datatype will now bind to the
      cx_Oracle.FIXED_NCHAR DBAPI data bindings when used in a bound
      parameter, which supplies proper comparison behavior against a
      variable-length string. Previously, the sqltypes.NCHAR datatype
      would bind to cx_oracle.NCHAR which is not fixed length; the
      sqltypes.CHAR datatype already binds to cx_Oracle.FIXED_CHAR so
      it is now consistent that sqltypes.NCHAR binds to
      cx_Oracle.FIXED_NCHAR.  References: #4913
    + [oracle] [usecase] Added dialect-level flag encoding_errors to
      the cx_Oracle dialect, which can be specified as part of
      create_engine(). This is passed to SQLAlchemy’s unicode decoding
      converter under Python 2, and to cx_Oracle’s cursor.var() object
      as the encodingErrors parameter under Python 3, for the very
      unusual case that broken encodings are present in the target
      database which cannot be fetched unless error handling is
      relaxed. The value is ultimately one of the Python “encoding
      errors” parameters passed to decode().  References: #4799
  * firebird
    + [firebird] [bug] Added additional “disconnect” message “Error
      writing data to the connection” to Firebird disconnection
      detection. Pull request courtesy lukens.  References: #4903
  * misc
    + [bug] [tests] Fixed test failures which would occur with newer
      SQLite as of version 3.30 or greater, due to their addition of
      nulls ordering syntax as well as new restrictions on aggregate
      functions. Pull request courtesy Nils Philippsen.  References:
    + [bug] [installation] [windows] Added a workaround for a
      setuptools-related failure that has been observed as occurring
      on Windows installations, where setuptools is not correctly
      reporting a build error when the MSVC build dependencies are not
      installed and therefore not allowing graceful degradation into
      non C extensions builds.  References: #4967

Thu Nov 14 15:17:51 UTC 2019 - Tomáš Chvátal <>

- This package needs full fledged python on runtime so make sure
  we require it

Wed Oct 30 13:03:18 UTC 2019 - Tomáš Chvátal <>

- Update to 1.3.10:
  * Fixed regression in selectinload loader strategy
  * Passing a plain string expression to Session.query() is deprecated
  * A warning is emitted for a condition in which the Session may
    implicitly swap an object out of the identity map for another one
    with the same primary key

Sat Aug 31 04:34:30 UTC 2019 - Arun Persaud <>

- update to version 1.3.8:
  * orm
    + Fixed bug where Load objects were not pickleable due to
      mapper/relationship state in the internal context
      dictionary. These objects are now converted to picklable using
      similar techniques as that of other elements within the loader
      option system that have long been serializable.  References:
    + Added support for the use of an Enum datatype using Python
      pep-435 enumeration objects as values for use as a primary key
      column mapped by the ORM. As these values are not inherently
      sortable, as required by the ORM for primary keys, a new
      TypeEngine.sort_key_function attribute is added to the typing
      system which allows any SQL type to implement a sorting for
      Python objects of its type which is consulted by the unit of
      work. The Enum type then defines this using the database value
      of a given enumeration. The sorting scheme can be also be
      redefined by passing a callable to the Enum.sort_key_function
      parameter. Pull request courtesy Nicolas Caniart.  References:
  * engine
    + Added new parameter create_engine.hide_parameters which when set
      to True will cause SQL parameters to no longer be logged, nor
      rendered in the string representation of a StatementError
      object.  References: #4815
    + Fixed an issue whereby if the dialect “initialize” process which
      occurs on first connect would encounter an unexpected exception,
      the initialize process would fail to complete and then no longer
      attempt on subsequent connection attempts, leaving the dialect
      in an un-initialized, or partially initialized state, within the
      scope of parameters that need to be established based on
      inspection of a live connection. The “invoke once” logic in the
      event system has been reworked to accommodate for this
      occurrence using new, private API features that establish an
      “exec once” hook that will continue to allow the initializer to
      fire off on subsequent connections, until it completes without
      raising an exception. This does not impact the behavior of the
      existing once=True flag within the event system.  References:
  * postgresql
    + Revised the approach for the just added support for the psycopg2
      “execute_values()” feature added in 1.3.7 for #4623. The
      approach relied upon a regular expression that would fail to
      match for a more complex INSERT statement such as one which had
      subqueries involved. The new approach matches exactly the string
      that was rendered as the VALUES clause.  References: #4623
    + Fixed bug where Postgresql operators such as
      postgresql.ARRAY.Comparator.contains() and
      postgresql.ARRAY.Comparator.contained_by() would fail to
      function correctly for non-integer values when used against a
      postgresql.array object, due to an erroneous assert statement.
      References: #4822
    + Added support for reflection of CHECK constraints that include
      the special PostgreSQL qualifier “NOT VALID”, which can be
      present for CHECK constraints that were added to an exsiting
      table with the directive that they not be applied to existing
      data in the table. The PostgreSQL dictionary for CHECK
      constraints as returned by Inspector.get_check_constraints() may
      include an additional entry dialect_options which within will
      contain an entry "not_valid": True if this symbol is
      detected. Pull request courtesy Bill Finn.  References: #4824
  * sqlite
    + Fixed bug where a FOREIGN KEY that was set up to refer to the
      parent table by table name only without the column names would
      not correctly be reflected as far as setting up the “referred
      columns”, since SQLite’s PRAGMA does not report on these columns
      if they weren’t given explicitly. For some reason this was
      harcoded to assume the name of the local column, which might
      work for some cases but is not correct. The new approach
      reflects the primary key of the referred table and uses the
      constraint columns list as the referred columns list, if the
      remote column(s) aren’t present in the reflected pragma
      directly.  References: #4810

Sun Aug 25 17:59:04 UTC 2019 - Arun Persaud <>

- update to version 1.3.7:
  * orm
    + Fixed regression caused by new selectinload for many-to-one
      logic where a primaryjoin condition not based on real foreign
      keys would cause KeyError if a related object did not exist for
      a given key value on the parent object.  References: #4777
    + Fixed bug where using Query.first() or a slice expression in
      conjunction with a query that has an expression based “offset”
      applied would raise TypeError, due to an “or” conditional
      against “offset” that did not expect it to be a SQL expression
      as opposed to an integer or None.  References: #4803
  * sql
    + Fixed issue where Index object which contained a mixture of
      functional expressions which were not resolvable to a particular
      column, in combination with string-based column names, would
      fail to initialize its internal state correctly leading to
      failures during DDL compilation.  References: #4778
    + Fixed bug where TypeEngine.column_expression() method would not
      be applied to subsequent SELECT statements inside of a UNION or
      other CompoundSelect, even though the SELECT statements are
      rendered at the topmost level of the statement. New logic now
      differentiates between rendering the column expression, which is
      needed for all SELECTs in the list, vs. gathering the returned
      data type for the result row, which is needed only for the first
      SELECT.  References: #4787
    + Fixed issue where internal cloning of SELECT constructs could
      lead to a key error if the copy of the SELECT changed its state
      such that its list of columns changed. This was observed to be
      occurring in some ORM scenarios which may be unique to 1.3 and
      above, so is partially a regression fix.  References: #4780
  * postgresql
    + Added new dialect flag for the psycopg2 dialect,
      executemany_mode which supersedes the previous experimental
      use_batch_mode flag. executemany_mode supports both the “execute
      batch” and “execute values” functions provided by psycopg2, the
      latter which is used for compiled insert() constructs. Pull
      request courtesy Yuval Dinari.  See also: Psycopg2 Fast
      Execution Helpers; References: #4623
  * mysql
    + The MySQL dialects will emit “SET NAMES” at the start of a
      connection when charset is given to the MySQL driver, to appease
      an apparent behavior observed in MySQL 8.0 that raises a
      collation error when a UNION includes string columns unioned
      against columns of the form CAST(NULL AS CHAR(..)), which is
      what SQLAlchemy’s polymorphic_union function does. The issue
      seems to have affected PyMySQL for at least a year, however has
      recently appeared as of mysqlclient 1.4.4 based on changes in
      how this DBAPI creates a connection. As the presence of this
      directive impacts three separate MySQL charset settings which
      each have intricate effects based on their presense, SQLAlchemy
      will now emit the directive on new connections to ensure correct
      behavior.  References: #4804
    + Added another fix for an upstream MySQL 8 issue where a case
      sensitive table name is reported incorrectly in foreign key
      constraint reflection, this is an extension of the fix first
      added for #4344 which affects a case sensitive column name. The
      new issue occurs through MySQL 8.0.17, so the general logic of
      the 88718 fix remains in place.  See also: - upstream bug;
      References: #4751
    + Added reserved words ARRAY and MEMBER to the MySQL reserved
      words list, as MySQL 8.0 has now made these reserved.
      References: #4783
  * sqlite
    + The dialects that support json are supposed to take arguments
      json_serializer and json_deserializer at the create_engine()
      level, however the SQLite dialect calls them _json_serilizer and
      _json_deserilalizer. The names have been corrected, the old
      names are accepted with a change warning, and these parameters
      are now documented as create_engine.json_serializer and
      create_engine.json_deserializer.  References: #4798
    + Fixed bug where usage of “PRAGMA table_info” in SQLite dialect
      meant that reflection features to detect for table existence,
      list of table columns, and list of foreign keys, would default
      to any table in any attached database, when no schema name was
      given and the table did not exist in the base schema. The fix
      explicitly runs PRAGMA for the ‘main’ schema and then the ‘temp’
      schema if the ‘main’ returned no rows, to maintain the behavior
      of tables + temp tables in the “no schema” namespace, attached
      tables only in the “schema” namespace.  References: #4793
  * mssql
    + Added new mssql.try_cast() construct for SQL Server which emits
      “TRY_CAST” syntax. Pull request courtesy Leonel Atencio.
      References: #4782
  * misc
    + Fixed issue in event system where using the once=True flag with
      dynamically generated listener functions would cause event
      registration of future events to fail if those listener
      functions were garbage collected after they were used, due to an
      assumption that a listened function is strongly referenced. The
      “once” wrapped is now modified to strongly reference the inner
      function persistently, and documentation is updated that using
      “once” does not imply automatic de-registration of listener
      functions.  References: #4794

Mon Jul 22 16:08:19 UTC 2019 - Todd R <>

- update to version 1.3.6
  + orm
    * [feature] Added new loader option method Load.options()
      which allows loader options to be constructed hierarchically,
      so that many sub-options can be applied to a particular path
      without needing to call defaultload() many times.
    * [bug] Fixed regression caused by #4365 where a join from an
      entity to itself without using aliases no longer raises an
      informative error message, instead failing on an assertion.
      The informative error condition has been restored.
    * [bug] Fixed an issue where the orm._ORMJoin.join() method,
      which is a not-internally-used ORM-level method that exposes
      what is normally an internal process of Query.join(), did
      not propagate the full and outerjoin keyword arguments
    * [bug] Fixed bug where a many-to-one relationship that
      specified uselist=True would fail to update correctly during
      a primary key change where a related column needs to change.
    * [bug] Fixed bug where the detection for many-to-one or
      one-to-one use with a “dynamic” relationship, which is an
      invalid configuration, would fail to raise if the 
      relationship were configured with uselist=True. The current
      fix is that it warns, instead of raises, as this would
      otherwise be backwards incompatible, however in a future
      release it will be a raise.
    * [bug] Fixed bug where a synonym created against a mapped
      attribute that does not exist yet, as is the case when it
      refers to backref before mappers are configured, would raise
      recursion errors when trying to test for attributes on it
      which ultimately don’t exist (as occurs when the classes are
      run through Sphinx autodoc), as the unconfigured state of
      the synonym would put it into an attribute not found loop.
    * [performance] The optimzation applied to selectin loading
      in #4340 where a JOIN is not needed to eagerly load related
      items is now applied to many-to-one relationships as well,
      so that only the related table is queried for a simple join
      condition. In this case, the related items are queried based
      on the value of a foreign key column on the parent; if these
      columns are deferred or otherwise not loaded on any of the
      parent objects in the collection, the loader falls back to the
      JOIN method.
  + engine
    * [bug] Fixed bug where using reflection function such as
      MetaData.reflect() with an Engine object that had execution
      options applied to it would fail, as the resulting
      OptionEngine proxy object failed to include a .engine
      attribute used within the reflection routines.
  + sql
    * [bug] Adjusted the initialization for Enum to minimize how
      often it invokes the .__members__ attribute of a given
      PEP-435 enumeration object, to suit the case where this
      attribute is expensive to invoke, as is the case for some
      popular third party enumeration libraries.
    * [bug] [postgresql] Fixed issue where the array_agg construct
      in combination with FunctionElement.filter() would not
      produce the correct operator precedence in combination
      with the array index operator.
    * [bug] Fixed an unlikely issue where the “corresponding
      column” routine for unions and other CompoundSelect objects
      could return the wrong column in some overlapping column
      situtations, thus potentially impacting some ORM operations
      when set operations are in use, if the underlying select()
      constructs were used previously in other similar kinds of
      routines, due to a cached value not being cleared.
  + postgresql
    * [usecase] Added support for reflection of indexes on
      PostgreSQL partitioned tables, which was added to PostgreSQL
      as of version 11.
    * [usecase] Added support for multidimensional Postgresql array
      literals via nesting the postgresql.array object within
      another one. The multidimensional array type is detected
  + mysql
    * [bug] Fixed bug where the special logic to render “NULL” for
      the TIMESTAMP datatype when nullable=True would not work if the
      column’s datatype were a TypeDecorator or a Variant. The logic
      now ensures that it unwraps down to the original TIMESTAMP so
      that this special case NULL keyword is correctly rendered when
    * [bug] Enhanced MySQL/MariaDB version string parsing to
      accommodate for exotic MariaDB version strings where the
      “MariaDB” word is embedded among other alphanumeric
      characters such as “MariaDBV1”. This detection is critical
      in order to correctly accommodate for API features that have
      split between MySQL and MariaDB such as the
      “transaction_isolation” system variable.
  + sqlite
    * [usecase] Added support for composite (tuple) IN operators
      with SQLite, by rendering the VALUES keyword for this backend.
      As other backends such as DB2 are known to use the same syntax,
      the syntax is enabled in the base compiler using a dialect-level

      “empty IN tuple” expressions for SQLite when using “in_()”
      between a tuple value and an empty set.

    * [bug] Ensured that the queries used to reflect indexes and
      view definitions will explicitly CAST string parameters into
      NVARCHAR, as many SQL Server drivers frequently treat string
      values, particularly those with non-ascii characters or
      larger string values, as TEXT which often don’t compare
      correctly against VARCHAR characters in SQL Server’s
      information schema tables for some reason. These CAST
      operations already take place for reflection queries against
      SQL Server information_schema. tables but were missing from
      three additional queries that are against sys.tables.

- update to version 1.3.5:
  * orm
    + Fixed a series of related bugs regarding joined table
      inheritance more than two levels deep, in conjunction with
      modification to primary key values, where those primary key
      columns are also linked together in a foreign key relationship
      as is typical for joined table inheritance. The intermediary
      table in a three-level inheritance hierachy will now get its
      UPDATE if only the primary key value has changed and
      passive_updates=False (e.g. foreign key constraints not being
      enforced), whereas before it would be skipped; similarly, with
      passive_updates=True (e.g. ON UPDATE CASCADE in effect), the
      third-level table will not receive an UPDATE statement as was
      the case earlier which would fail since CASCADE already modified
      it. In a related issue, a relationship linked to a three-level
      inheritance hierarchy on the primary key of an intermediary
      table of a joined-inheritance hierarchy will also correctly have
      its foreign key column updated when the parent object’s primary
      key is modified, even if that parent object is a subclass of the
      linked parent class, whereas before these classes would not be
      counted.  References: #4723
    + Fixed bug where the Mapper.all_orm_descriptors accessor would
      return an entry for the Mapper itself under the declarative
      __mapper___ key, when this is not a descriptor. The
      .is_attribute flag that’s present on all InspectionAttr objects
      is now consulted, which has also been modified to be True for an
      association proxy, as it was erroneously set to False for this
      object.  References: #4729
    + Fixed regression in Query.join() where the aliased=True flag
      would not properly apply clause adaptation to filter criteria,
      if a previous join were made to the same entity. This is because
      the adapters were placed in the wrong order. The order has been
      reversed so that the adapter for the most recent aliased=True
      call takes precedence as was the case in 1.2 and earlier. This
      broke the “elementtree” examples among other things.
      References: #4704
    + Replaced the Python compatbility routines for getfullargspec()
      with a fully vendored version from Python 3.3. Originally,
      Python was emitting deprecation warnings for this function in
      Python 3.8 alphas. While this change was reverted, it was
      observed that Python 3 implementations for getfullargspec() are
      an order of magnitude slower as of the 3.4 series where it was
      rewritten against Signature. While Python plans to improve upon
      this situation, SQLAlchemy projects for now are using a simple
      replacement to avoid any future issues.  References: #4674
    + Reworked the attribute mechanics used by AliasedClass to no
      longer rely upon calling __getattribute__ on the MRO of the
      wrapped class, and to instead resolve the attribute normally on
      the wrapped class using getattr(), and then unwrap/adapt
      that. This allows a greater range of attribute styles on the
      mapped class including special __getattr__() schemes; but it
      also makes the code simpler and more resilient in general.
      References: #4694
  * sql
    + Fixed a series of quoting issues which all stemmed from the
      concept of the literal_column() construct, which when being
      “proxied” through a subquery to be referred towards by a label
      that matches its text, the label would not have quoting rules
      applied to it, even if the string in the Label were set up as a
      quoted_name construct. Not applying quoting to the text of the
      Label is a bug because this text is strictly a SQL identifier
      name and not a SQL expression, and the string should not have
      quotes embedded into it already unlike the literal_column()
      which it may be applied towards. The existing behavior of a
      non-labeled literal_column() being propagated as is on the
      outside of a subquery is maintained in order to help with manual
      quoting schemes, although it’s not clear if valid SQL can be
      generated for such a construct in any case.  References: #4730
  * postgresql
    + Fixed bug where PostgreSQL dialect could not correctly reflect
      an ENUM datatype that has no members, returning a list with None
      for the get_enums() call and raising a TypeError when reflecting
      a column which has such a datatype. The inspection now returns
      an empty list.  References: #4701
    + Added support for column sorting flags when reflecting indexes
      for PostgreSQL, including ASC, DESC, NULLSFIRST, NULLSLAST. Also
      adds this facility to the reflection system in general which can
      be applied to other dialects in future releases. Pull request
      courtesy Eli Collins.  References: #4717
  * mysql
    + Fixed bug where MySQL ON DUPLICATE KEY UPDATE would not
      accommodate setting a column to the value NULL. Pull request
      courtesy Lukáš Banič.  References: #4715

Sat Jun  8 23:09:01 UTC 2019 - Arun Persaud <>

- update to version 1.3.4:
  * orm
    + Fixed issue where the AttributeEvents.active_history flag would
      not be set for an event listener that propgated to a subclass
      via the AttributeEvents.propagate flag. This bug has been
      present for the full span of the AttributeEvents system.
      References: #4695
    + Fixed regression where new association proxy system was still
      not proxying hybrid attributes when they made use of the
      @hybrid_property.expression decorator to return an alternate SQL
      expression, or when the hybrid returned an arbitrary
      PropComparator, at the expression level. This involved futher
      generalization of the heuristics used to detect the type of
      object being proxied at the level of QueryableAttribute, to
      better detect if the descriptor ultimately serves mapped classes
      or column expressions.  References: #4690
    + Applied the mapper “configure mutex” against the declarative
      class mapping process, to guard against the race which can occur
      if mappers are used while dynamic module import schemes are
      still in the process of configuring mappers for related
      classes. This does not guard against all possible race
      conditions, such as if the concurrent import has not yet
      encountered the dependent classes as of yet, however it guards
      against as much as possible within the SQLAlchemy declarative
      process.  References: #4686
    + A warning is now emitted for the case where a transient object
      is being merged into the session with Session.merge() when that
      object is already transient in the Session. This warns for the
      case where the object would normally be double-inserted.
      References: #4647
    + Fixed regression in new relationship m2o comparison logic first
      introduced at Improvement to the behavior of many-to-one query
      expressions when comparing to an attribute that is persisted as
      NULL and is in an un-fetched state in the mapped instance. Since
      the attribute has no explicit default, it needs to default to
      NULL when accessed in a persistent setting.  References: #4676
  * engine
    + Moved the “rollback” which occurs during dialect initialization
      so that it occurs after additional dialect-specific initialize
      steps, in particular those of the psycopg2 dialect which would
      inadvertently leave transactional state on the first new
      connection, which could interfere with some psycopg2-specific
      APIs which require that no transaction is started. Pull request
      courtesy Matthew Wilkes.  References: #4663
  * sql
    + Fixed that the GenericFunction class was inadvertently
      registering itself as one of the named functions. Pull request
      courtesy Adrien Berchet.  References: #4653
    + Fixed issue where double negation of a boolean column wouldn’t
      reset the “NOT” operator.  References: #4618
    + The GenericFunction namespace is being migrated so that function
      names are looked up in a case-insensitive manner, as SQL
      functions do not collide on case sensitive differences nor is
      this something which would occur with user-defined functions or
      stored procedures. Lookups for functions declared with
      GenericFunction now use a case insensitive scheme, however a
      deprecation case is supported which allows two or more
      GenericFunction objects with the same name of different cases to
      exist, which will cause case sensitive lookups to occur for that
      particular name, while emitting a warning at function
      registration time. Thanks to Adrien Berchet for a lot of work on
      this complicated feature.  References: #4569
  * postgresql
    + Fixed an issue where the “number of rows matched” warning would
      emit even if the dialect reported
      “supports_sane_multi_rowcount=False”, as is the case for
      psycogp2 with use_batch_mode=True and others.  References: #4661
  * mysql
    + Added support for DROP CHECK constraint which is required by
      MySQL 8.0.16 to drop a CHECK constraint; MariaDB supports plain
      DROP CONSTRAINT. The logic distinguishes between the two
      syntaxes by checking the server version string for MariaDB
      presence. Alembic migrations has already worked around this
      issue by implementing its own DROP for MySQL / MariaDB CHECK
      constraints, however this change implements it straight in Core
      so that its available for general use. Pull request courtesy
      Hannes Hansen.  References: #4650
  * mssql
    + Added support for SQL Server filtered indexes, via the
      mssql_where parameter which works similarly to that of the
      postgresql_where index function in the PostgreSQL dialect.  See
      also: Filtered Indexes References: #4657
    + Added error code 20047 to “is_disconnect” for pymssql. Pull
      request courtesy Jon Schuff.  References: #4680
  * misc
    + Removed errant “” symbol from which
      created an undesirable warning message.  References: #4625

Sun Apr 21 22:00:19 UTC 2019 - Arun Persaud <>

- update to version 1.3.3:
  * orm
    + Fixed 1.3 regression in new “ambiguous FROMs” query logic
      introduced in Query.join() handles ambiguity in deciding the
      “left” side more explicitly where a Query that explicitly places
      an entity in the FROM clause with Query.select_from() and also
      joins to it using Query.join() would later cause an “ambiguous
      FROM” error if that entity were used in additional joins, as the
      entity appears twice in the “from” list of the Query. The fix
      resolves this ambiguity by folding the standalone entity into
      the join that it’s already a part of in the same way that
      ultimately happens when the SELECT statement is rendered.
      References: #4584
    + Adjusted the Query.filter_by() method to not call and()
      internally against multiple criteria, instead passing it off to
      Query.filter() as a series of criteria, instead of a single
      criteria. This allows Query.filter_by() to defer to
      Query.filter()’s treatment of variable numbers of clauses,
      including the case where the list is empty. In this case, the
      Query object will not have a .whereclause, which allows
      subsequent “no whereclause” methods like Query.select_from() to
      behave consistently.  References: #4606
  * postgresql
    + Fixed regression from release 1.3.2 caused by #4562 where a URL
      that contained only a query string and no hostname, such as for
      the purposes of specifying a service file with connection
      information, would no longer be propagated to psycopg2
      properly. The change in #4562 has been adjusted to further suit
      psycopg2’s exact requirements, which is that if there are any
      connection parameters whatsoever, the “dsn” parameter is no
      longer required, so in this case the query string parameters are
      passed alone.  References: #4601
  * mssql
    + Fixed issue in SQL Server dialect where if a bound parameter
      were present in an ORDER BY expression that would ultimately not
      be rendered in the SQL Server version of the statement, the
      parameters would still be part of the execution parameters,
      leading to DBAPI-level errors. Pull request courtesy Matt
      Lewellyn.  References: #4587
  * misc
    + Fixed behavioral regression as a result of deprecating the
      “use_threadlocal” flag for Pool, where the SingletonThreadPool
      no longer makes use of this option which causes the “rollback on
      return” logic to take place when the same Engine is used
      multiple times in the context of a transaction to connect or
      implicitly execute, thereby cancelling the transaction. While
      this is not the recommended way to work with engines and
      connections, it is nonetheless a confusing behavioral change as
      when using SingletonThreadPool, the transaction should stay open
      regardless of what else is done with the same engine in the same
      thread. The use_threadlocal flag remains deprecated however the
      SingletonThreadPool now implements its own version of the same
      logic.  References: #4585
    + Fixed bug where using copy.copy() or copy.deepcopy() on
      MutableList would cause the items within the list to be
      duplicated, due to an inconsistency in how Python pickle and
      copy both make use of __getstate__() and __setstate__()
      regarding lists. In order to resolve, a __reduce_ex__ method had
      to be added to MutableList. In order to maintain backwards
      compatibility with existing pickles based on __getstate__(), the
      __setstate__() method remains as well; the test suite asserts
      that pickles made against the old version of the class can still
      be deserialized by the pickle module.  References: #4603

Wed Apr 10 15:37:48 UTC 2019 - Arun Persaud <>

- update to version 1.3.2:
  * orm
    + [orm] [bug] [ext] Restored instance-level support for plain
      Python descriptors, e.g. @property objects, in conjunction with
      association proxies, in that if the proxied object is not within
      ORM scope at all, it gets classified as “ambiguous” but is
      proxed directly. For class level access, a basic class
      level"__get__()" now returns the
      AmbiguousAssociationProxyInstance directly, rather than raising
      its exception, which is the closest approximation to the
      previous behavior that returned the AssociationProxy itself
      that’s possible. Also improved the stringification of these
      objects to be more descriptive of current state.  References:
      #4573, #4574
    + [orm] [bug] Fixed bug where use of with_polymorphic() or other
      aliased construct would not properly adapt when the aliased
      target were used as the Select.correlate_except() target of a
      subquery used inside of a column_property(). This required a fix
      to the clause adaption mechanics to properly handle a selectable
      that shows up in the “correlate except” list, in a similar
      manner as which occurs for selectables that show up in the
      “correlate” list. This is ultimately a fairly fundamental bug
      that has lasted for a long time but it is hard to come across
      it.  References: #4537
    + [orm] [bug] Fixed regression where a new error message that was
      supposed to raise when attempting to link a relationship option
      to an AliasedClass without using PropComparator.of_type() would
      instead raise an AttributeError. Note that in 1.3, it is no
      longer valid to create an option path from a plain mapper
      relationship to an AliasedClass without using
      PropComparator.of_type().  References: #4566
  * sql
    + [sql] [bug] [documentation] Thanks to TypeEngine methods
      bind_expression, column_expression work with Variant,
      type-specific types, we no longer need to rely on recipes that
      subclass dialect-specific types directly, TypeDecorator can now
      handle all cases. Additionally, the above change made it
      slightly less likely that a direct subclass of a base SQLAlchemy
      type would work as expected, which could be
      misleading. Documentation has been updated to use TypeDecorator
      for these examples including the PostgreSQL “ArrayOfEnum”
      example datatype and direct support for the “subclass a type
      directly” has been removed.  References: #4580
  * postgresql
    + [postgresql] [feature] Added support for parameter-less
      connection URLs for the psycopg2 dialect, meaning, the URL can
      be passed to create_engine() as "postgresql+psycopg2://" with no
      additional arguments to indicate an empty DSN passed to libpq,
      which indicates to connect to “localhost” with no username,
      password, or database given. Pull request courtesy Julian
      Mehnle.  References: #4562
    + [postgresql] [bug] Modified the Select.with_for_update.of
      parameter so that if a join or other composed selectable is
      passed, the individual Table objects will be filtered from it,
      allowing one to pass a join() object to the parameter, as occurs
      normally when using joined table inheritance with the ORM. Pull
      request courtesy Raymond Lu.  References: #4550

- update to version 1.2.14:
  * orm
    + [orm] [bug] Fixed bug in Session.bulk_update_mappings() where
      alternate mapped attribute names would result in the primary key
      column of the UPDATE statement being included in the SET clause,
      as well as the WHERE clause; while usually harmless, for SQL
      Server this can raise an error due to the IDENTITY column. This
      is a continuation of the same bug that was fixed in #3849, where
      testing was insufficient to catch this additional flaw.
      References: #4357
    + [orm] [bug] Fixed a minor performance issue which could in some
      cases add unnecessary overhead to result fetching, involving the
      use of ORM columns and entities that include those same columns
      at the same time within a query. The issue has to do with hash /
      eq overhead when referring to the column in different ways.
      References: #4347
  * mysql
    + [mysql] [bug] Fixed regression caused by #4344 released in
      1.2.13, where the fix for MySQL 8.0’s case sensitivity problem
      with referenced column names when reflecting foreign key
      referents is worked around using the information_schema.columns
      view. The workaround was failing on OSX /
      lower_case_table_names=2 which produces non-matching casing for
      the information_schema.columns vs. that of SHOW CREATE TABLE, so
      in case-insensitive SQL modes case-insensitive matching is now
      used.  References: #4361

Thu Nov  1 22:48:27 UTC 2018 - Arun Persaud <>

- update to version 1.2.13:
  * orm
    + [orm] [bug] Fixed bug where “dynamic” loader needs to explicitly
      set the “secondary” table in the FROM clause of the query, to
      suit the case where the secondary is a join object that is
      otherwise not pulled into the query from its columns alone.
      References: #4349
  * orm declarative
    + [bug] [declarative] [orm] Fixed regression caused by #4326 in
      version 1.2.12 where using declared_attr with a mixin in
      conjunction with orm.synonym() would fail to map the synonym
      properly to an inherited subclass.  References: #4350
    + [bug] [declarative] [orm] The column conflict resolution
      technique discussed at Resolving Column Conflicts is now
      functional for a Column that is also a primary key
      column. Previously, a check for primary key columns declared on
      a single-inheritance subclass would occur before the column copy
      were allowed to pass.  References: #4352
  * sql
    + [sql] [feature] Refactored SQLCompiler to expose a
      SQLCompiler.group_by_clause() method similar to the
      SQLCompiler.order_by_clause() and SQLCompiler.limit_clause()
      methods, which can be overridden by dialects to customize how
      GROUP BY renders. Pull request courtesy Samuel Chou.
    + [sql] [bug] Fixed bug where the Enum.create_constraint flag on
      the Enum datatype would not be propagated to copies of the type,
      which affects use cases such as declarative mixins and abstract
      bases.  References: #4341
  * postgresql

      function to receive multiple ORDER BY elements, previously only
      a single element was accepted.  References: #4337
  * mysql
    + [mysql] [bug] Added word function to the list of reserved words

    + [mysql] [bug] Added a workaround for a MySQL bug #88718
      introduced in the 8.0 series, where the reflection of a foreign
      key constraint is not reporting the correct case sensitivity for
      the referred column, leading to errors during use of the
      reflected constraint such as when using the automap
      extension. The workaround emits an additional query to the
      information_schema tables in order to retrieve the correct case
      sensitive name.  References: #4344
  * misc
    + [misc] [bug] Fixed issue where part of the utility language
      helper internals was passing the wrong kind of argument to the
      Python __import__ builtin as the list of modules to be
      imported. The issue produced no symptoms within the core library
      but could cause issues with external applications that redefine
      the __import__ builtin or otherwise instrument it. Pull request

      these cleanups occur during interpreter shutdown. Pull request
      courtesy Romuald Brunet.
    + [orm] [bug] Fixed bug where use of Lateral construct in
      conjunction with Query.join() as well as
      Query.select_entity_from() would not apply clause adaption to
      the right side of the join. “lateral” introduces the use case of
      the right side of a join being correlatable. Previously,
      adaptation of this clause wasn’t considered. Note that in 1.2
      only, a selectable introduced by Query.subquery() is still not
      adapted due to #4304; the selectable needs to be produced by the
      select() function to be the right side of the “lateral” join.
      References: #4334
    + [orm] [bug] Fixed 1.2 regression caused by #3472 where the
      handling of an “updated_at” style column within the context of a

      deleted following the update, meaning both that a column with a
      Python-side value generator would show the now-deleted value
      that was emitted for the UPDATE before the DELETE (which was not
      the previous behavor), as well as that a SQL- emitted value
      generator would have the attribute expired, meaning the previous
      value would be unreachable due to the row having been deleted
      and the object detached from the session.The “postfetch” logic
      that was added as part of #3472 is now skipped entirely for an
      object that ultimately is to be deleted.  References: #4327

      for attributes would receive the expression proxy delivered by a
      hybrid attribute at the class level, and not the hybrid
      attribute itself, when receiving the descriptor via the
      @declared_attr callable on a subclass of an already-mapped

  * orm declarative
    + [bug] [declarative] [orm] Fixed issue in previously untested use
      case, allowing a declarative mapped class to inherit from a
      classically-mapped class outside of the declarative base,
      including that it accommodates for unmapped intermediate
      classes. An unmapped intermediate class may specify
      __abstract__, which is now interpreted correctly, or the
      intermediate class can remain unmarked, and the classically
      mapped base class will be detected within the hierarchy
      regardless. In order to anticipate existing scenarios which may
      be mixing in classical mappings into existing declarative
      hierarchies, an error is now raised if multiple mapped bases are
      detected for a given class.   References: #4321

      an expression rendered in a boolean context on a non-native
      boolean backend would be compared to 1/0 even though it is
      already an implcitly boolean expression, when
      ColumnElement.self_group() were used. While this does not affect
      the user-friendly backends (MySQL, SQLite) it was not handled by
      Oracle (and possibly SQL Server). Whether or not the expression
      is implicitly boolean on any database is now determined up front
      as an additional check to not generate the integer comparison

      that a SELECT statement in the WHERE clause for such a statement
      will try to auto-correlate back to these additional tables in
      the parent UPDATE/DELETE or unconditionally correlate if
      Select.correlate() is used. Note that auto-correlation raises an
      error if the SELECT statement would have no FROM clauses as a
      result, which can now occur if the parent UPDATE/DELETE
      specifies the same tables in its additional set of tables;

      regression in 1.2 as well as an incorrect result regarding the
      “baked” lazy loader, involving the generation of cache keys from
      the original Query object’s loader options. If the loader
      options were built up in a “branched” style using common base
      elements for multiple options, the same options would be
      rendered into the cache key repeatedly, causing both a
      performance issue as well as generating the wrong cache
      key. This is fixed, along with a performance improvement when
      such “branched” options are applied via Query.options() to
      prevent the same option objects from being applied repeatedly.

      is now replaced with a utf8mb4 equivalent. Documentation is also
      updated for the MySQL dialect to specify utf8mb4 in all
      examples. Additional changes have been made to the test suite to
      use utf8mb3 charsets and databases (there seem to be collation

- update to version 1.2.8:
  * orm
    + [orm] [bug] Fixed regression in 1.2.7 caused by #4228, which 
      itself was fixing a 1.2-level regression, where the query_cls
      callable passed to a Session was assumed to be a subclass of 
      Query with class method availability, as opposed to an 
      arbitrary callable. In particular, the dogpile caching example 
      illustrates query_cls as a function and not a Query subclass. 
      References: #4256
    + [orm] [bug] Fixed a long-standing regression that occurred in 
      version 1.0, which prevented the use of a custom MapperOption 
      that alters the _params of a Query object for a lazy load, 
      since the lazy loader itself would overwrite those parameters. 
      This applies to the “temporal range” example on the wiki. Note 
      however that the Query.populate_existing() method is now 
      required in order to rewrite the mapper options associated with 
      an object already loaded in the identity map.
      As part of this change, a custom defined MapperOption will now 
      cause lazy loaders related to the target object to use a non-
      baked query by default unless the 
      MapperOption._generate_cache_key() method is implemented. In 
      particular, this repairs one regression which occured when 
      using the dogpile.cache “advanced” example, which was not 
      returning cached results and instead emitting SQL due to an 
      incompatibility with the baked query loader; with the change, 
      the RelationshipCache option included for many releases in the 
      dogpile example will disable the “baked” query altogether. Note 
      that the dogpile example is also modernized to avoid both of 
      these issues as part of issue #4258.  References: #4128
    + [orm] [bug] Fixed bug where the new 
      baked.Result.with_post_criteria() method would not interact 
      with a subquery-eager loader correctly, in that the “post 
      criteria” would not be applied to embedded subquery 
      eager loaders. This is related to #4128 in that the post 
      criteria feature is now used by the lazy loader.
    + [orm] [bug] Updated the dogpile.caching example to include new 
      structures that accommodate for the “baked” query system, which 
      is used by default within lazy loaders and some eager 
      relationship loaders. The dogpile.caching “relationship_caching” 
      and “advanced” examples were also broken due to #4256. The 
      issue here is also worked-around by the fix in #4128.

  * engine
    + [engine] [bug] Fixed connection pool issue whereby if a 
      disconnection error were raised during the connection pool’s 
      “reset on return” sequence in conjunction with an explicit 
      transaction opened against the enclosing Connection object 
      (such as from calling Session.close() without a rollback or 
      commit, or calling Connection.close() without first closing a 
      transaction declared with Connection.begin()), a double-checkin 
      would result, which could then lead towards concurrent 
      checkouts of the same connection. The double-checkin condition 
      is now prevented overall by an assertion, as well as the 
      specific double-checkin scenario has been fixed.  
      References: #4252
    + [engine] [bug] Fixed a reference leak issue where the values of

      values would encounter a tuple value, and fail to format the 
      message properly. Pull request courtesy Miguel Ventura.
  * mssql
    + [mssql] [bug] Fixed a 1.2 regression caused by #4061 where the 
      SQL Server “BIT” type would be considered to be “native 
      boolean”. The goal here was to avoid creating a CHECK 
      constraint on the column, however the bigger issue is that the 
      BIT value does not behave like a true/false constant and cannot 
      be interpreted as a standalone expression, e.g.  “WHERE 
      <column>”. The SQL Server dialect now goes back to being non-
      native boolean, but with an extra flag that still avoids 
      creating the CHECK constraint.  References: #4250
  * oracle
    + [oracle] [bug] The Oracle BINARY_FLOAT and BINARY_DOUBLE 
      datatypes now participate within cx_Oracle.setinputsizes(), 
      passing along NATIVE_FLOAT, so as to support the NaN value. 
      Additionally, oracle.BINARY_FLOAT, oracle.BINARY_DOUBLE and 
      oracle.DOUBLE_PRECISION now subclass Float, since these are 
      floating point datatypes, not decimal. These datatypes were 
      already defaulting the Float.asdecimal flag to False in line 
      with what Float already does.  References: #4264
    + [oracle] [bug] Added reflection capabilities for the 
      oracle.BINARY_FLOAT, oracle.BINARY_DOUBLE datatypes.
    + [oracle] [bug] Altered the Oracle dialect such that when an 
      Integer type is in use, the cx_Oracle.NUMERIC type is set up 
      for setinputsizes(). In SQLAlchemy 1.1 and earlier, 
      cx_Oracle.NUMERIC was passed for all numeric types 
      unconditionally, and in 1.2 this was removed to allow for 
      better numeric precision. However, for integers, some 
      database/client setups will fail to coerce boolean values 
      True/False into integers which introduces regressive behavior 
      when using SQLAlchemy 1.2. Overall, the setinputsizes logic 
      seems like it will need a lot more flexibility going forward so 
      this is a start for that.  References: #4259
  * misc
    + [bug] [ext] The horizontal sharding extension now makes use of 
      the identity token added to ORM identity keys as part of #4137, 
      when an object refresh or column-based deferred load or 
      unexpiration operation occurs.  Since we know the “shard” that 
      the object originated from, we make use of this value when 
      refreshing, thereby avoiding queries against other shards that 
      don’t match this object’s identity in any case.

    + [bug] [ext] Fixed a race condition which could occur if automap 
      AutomapBase.prepare() were used within a multi-threaded context 
      against other threads which may call configure_mappers() as a 
      result of use of other mappers. The unfinished mapping work of 
      automap is particularly sensitive to being pulled in by a 
      configure_mappers() step leading to errors.  References: #4266

      where the new “identity_token” element was not being correctly
      considered within the scope of a lazy load operation, when
      searching the identity map for a related many-to-one
      element. The new behavior will allow for making use of the
      “id_chooser” in order to determine the best identity key to
      retrieve from the identity map. In order to achieve this, some
      refactoring of 1.2’s “identity_token” approach has made some
      slight changes to the implementation of ShardedQuery which

    + [sql] [bug] Fixed a regression that occurred from the previous
      fix to #4204 in version 1.2.5, where a CTE that refers to itself
      after the CTE.alias() method has been called would not refer to
      iself correctly.  References: #4204
  * postgresql
    + [postgresql] [feature] Added support for “PARTITION BY” in
      Postgresql table definitions, using
      “postgresql_partition_by”. Pull request courtesy Vsevolod
  * mssql
    + [mssql] [bug] Adjusted the SQL Server version detection for
      pyodbc to only allow for numeric tokens, filtering out
      non-integers, since the dialect does tuple- numeric comparisons
      with this value. This is normally true for all known SQL Server
      / pyodbc drivers in any case.  References: #4227
  * oracle
    + [oracle] [bug] The minimum cx_Oracle version supported is 5.2
      (June 2015). Previously, the dialect asserted against version
      5.0 but as of 1.2.2 we are using some symbols that did not
      appear until 5.2.  References: #4211
  * misc
    + [bug] [declarative] Removed a warning that would be emitted when
      calling upon __table_args__, __mapper_args__ as named with a
      @declared_attr method, when called from a non-mapped declarative
      mixin. Calling these directly is documented as the approach to
      use when one is overidding one of these methods on a mapped
      class. The warning still emits for regular attribute names.

- update to version 1.2.5:
  * orm
    + [orm] [feature] Added new feature
      Query.only_return_tuples(). Causes the Query object to return
      keyed tuple objects unconditionally even if the query is against
      a single entity. Pull request courtesy Eric Atkin.
    + [orm] [bug] Fixed bug in new “polymorphic selectin” loading when
      a selection of polymorphic objects were to be partially loaded
      from a relationship lazy loader, leading to an “empty IN”
      condition within the load that raises an error for the “inline”
      form of “IN”. References: #4199
    + [orm] [bug] Fixed 1.2 regression where a mapper option that
      contains an AliasedClass object, as is typical when using the
      QueryableAttribute.of_type() method, could not be pickled. 1.1’s
      behavior was to omit the aliased class objects from the path, so
      this behavior is restored.  References: #4209
  * sql
    + [sql] [bug] Fixed bug in :class:.`CTE` construct along the same
      lines as that of #4204 where a CTE that was aliased would not
      copy itself correctly during a “clone” operation as is frequent
      within the ORM as well as when using the ClauseElement.params()
      method.  References: #4210
    + [sql] [bug] Fixed bug in CTE rendering where a CTE that was also
      turned into an Alias would not render its “ctename AS aliasname”
      clause appropriately if there were more than one reference to
      the CTE in a FROM clause.  References: #4204
    + [sql] [bug] Fixed bug in new “expanding IN parameter” feature
      where the bind parameter processors for values wasn’t working at
      all, tests failed to cover this pretty basic case which includes
      that ENUM values weren’t working.  References: #4198
  * postgresql
    + [postgresql] [bug] [py3k] Fixed bug in Postgresql COLLATE /
      ARRAY adjustment first introduced in #4006 where new behaviors
      in Python 3.7 regular expressions caused the fix to fail.  This
      change is also backported to: 1.1.18 References: #4208
  * mysql
    + [mysql] [bug] MySQL dialects now query the server version using
      SELECT @@version explicitly to the server to ensure we are
      getting the correct version information back. Proxy servers like
      MaxScale interfere with the value that is passed to the DBAPI’s
      connection.server_version value so this is no longer reliable.
      This change is also backported to: 1.1.18 References: #4205

Fri Feb 23 23:48:41 UTC 2018 -

- update to version 1.2.4:
  * orm
    + [orm] [bug] Fixed 1.2 regression in ORM versioning feature where
      a mapping against a select() or alias() that also used a
      versioning column against the underlying table would fail due to
      the check added as part of #3673.  References: #4193
  * engine
    + [engine] [bug] Fixed regression caused in 1.2.3 due to fix from
      #4181 where the changes to the event system involving Engine and
      OptionEngine did not accommodate for event removals, which would
      raise an AttributeError when invoked at the class level.
      References: #4190
  * sql
    + [sql] [bug] Fixed bug where CTE expressions would not have their
      name or alias name quoted when the given name is case sensitive
      or otherwise requires quoting. Pull request courtesy Eric Atkin.
      References: #4197

Sun Feb 18 17:09:28 UTC 2018 -

- update to version 1.2.3:
  * orm
    + [orm] [feature] Added new argument
      attributes.set_attribute.inititator to the
      attributes.set_attribute() function, allowing an event token
      received from a listener function to be propagated to subsequent
      set events.
    + [orm] [bug] Fixed issue in post_update feature where an UPDATE
      is emitted when the parent object has been deleted but the
      dependent object is not. This issue has existed for a long time
      however since 1.2 now asserts rows matched for post_update, this
      was raising an error.  This change is also backported to: 1.1.16
      References: #4187
    + [orm] [bug] Fixed regression caused by fix for issue #4116
      affecting versions 1.2.2 as well as 1.1.15, which had the effect
      of mis-calculation of the “owning class” of an AssociationProxy
      as the NoneType class in some declarative mixin/inheritance
      situations as well as if the association proxy were accessed off
      of an un-mapped class. The “figure out the owner” logic has been
      replaced by an in-depth routine that searches through the
      complete mapper hierarchy assigned to the class or subclass to
      determine the correct (we hope) match; will not assign the owner
      if no match is found. An exception is now raised if the proxy is
      used against an un-mapped instance.  This change is also
      backported to: 1.1.16 References: #4185
    + [orm] [bug] Fixed bug where the Bundle object did not correctly
      report upon the primary Mapper object represened by the bundle,
      if any. An immediate side effect of this issue was that the new
      selectinload loader strategy wouldn’t work with the horizontal
      sharding extension.  References: #4175
    + [orm] [bug] Fixed bug in concrete inheritance mapping where
      user-defined attributes such as hybrid properties that mirror
      the names of mapped attributes from sibling classes would be
      overwritten by the mapper as non-accessible at the instance
      level. Additionally ensured that user-bound descriptors are not
      implicitly invoked at the class level during the mapper
      configuration stage.  References: #4188
    + [orm] [bug] Fixed bug where the orm.reconstructor() event helper
      would not be recognized if it were applied to the __init__()
      method of the mapped class.  References: #4178
  * engine
    + [engine] [bug] Fixed bug where events associated with an Engine
      at the class level would be doubled when the
      Engine.execution_options() method were used. To achieve this,
      the semi-private class OptionEngine no longer accepts events
      directly at the class level and will raise an error; the class
      only propagates class-level events from its parent
      Engine. Instance-level events continue to work as before.
      References: #4181
    + [engine] [bug] The URL object now allows query keys to be
      specified multiple times where their values will be joined into
      a list. This is to support the plugins feature documented at
      CreateEnginePlugin which documents that “plugin” can be passed
      multiple times. Additionally, the plugin names can be passed to
      create_engine() outside of the URL using the new
      create_engine.plugins parameter.  References: #4170
  * sql
    + [sql] [feature] Added support for Enum to persist the values of
      the enumeration, rather than the keys, when using a Python
      pep-435 style enumerated object. The user supplies a callable
      function that will return the string values to be
      persisted. This allows enumerations against non-string values to
      be value-persistable as well. Pull request courtesy Jon Snyder.
      References: #3906
    + [sql] [bug] Fixed bug where the Enum type wouldn’t handle enum
      “aliases” correctly, when more than one key refers to the same
      value. Pull request courtesy Daniel Knell.  References: #4180
  * postgresql
    + [postgresql] [bug] Added “SSL SYSCALL error: Operation timed
      out” to the list of messages that trigger a “disconnect”
      scenario for the psycopg2 driver. Pull request courtesy André
      Cruz.  This change is also backported to: 1.1.16
    + [postgresql] [bug] Added “TRUNCATE” to the list of keywords
      accepted by the Postgresql dialect as an “autocommit”-triggering
      keyword. Pull request courtesy Jacob Hayes.  This change is also
      backported to: 1.1.16
  * sqlite
    + [sqlite] [bug] Fixed the import error raised when a platform has
      neither pysqlite2 nor sqlite3 installed, such that the
      sqlite3-related import error is raised, not the pysqlite2 one
      which is not the actual failure mode. Pull request courtesy
  * oracle
    + [oracle] [feature] The ON DELETE options for foreign keys are
      now part of Oracle reflection. Oracle does not support ON UPDATE
      cascades. Pull request courtesy Miroslav Shubernetskiy.
    + [oracle] [bug] Fixed bug in cx_Oracle disconnect detection, used
      by pre_ping and other features, where an error could be raised
      as DatabaseError which includes a numeric error code; previously
      we weren’t checking in this case for a disconnect code.
      References: #4182
  * misc
    + [bug] [pool] Fixed a fairly serious connection pool bug where a
      connection that is acquired after being refreshed as a result of
      a user-defined DisconnectionError or due to the 1.2-released
      “pre_ping” feature would not be correctly reset if the
      connection were returned to the pool by weakref cleanup
      (e.g. the front-facing object is garbage collected); the weakref
      would still refer to the previously invalidated DBAPI connection
      which would have the reset operation erroneously called upon it
      instead. This would lead to stack traces in the logs and a
      connection being checked into the pool without being reset,
      which can cause locking issues.  This change is also backported
      to: 1.1.16 References: #4184
    + [bug] [tests] A test added in 1.2 thought to confirm a Python
      2.7 behavior turns out to be confirming the behavior only as of
      Python 2.7.8. Python bug #8743 still impacts set comparison in
      Python 2.7.7 and earlier, so the test in question involving
      AssociationSet no longer runs for these older Python 2.7
      versions.  References: #3265

Sun Jan 28 18:53:04 UTC 2018 -

- update to version 1.2.2:
  * orm
    + [orm] [bug] Fixed 1.2 regression regarding new bulk_replace
      event where a backref would fail to remove an object from the
      previous owner when a bulk-assignment assigned the object to a
      new owner.  References: #4171
  * mysql
    + [mysql] [bug] Added more MySQL 8.0 reserved words to the MySQL
      dialect for quoting purposes. Pull request courtesy Riccardo
  * mssql
    + [mssql] [bug] Added ODBC error code 10054 to the list of error
      codes that count as a disconnect for ODBC / MSSQL server.
      References: #4164
  * oracle
    + [oracle] [bug] The cx_Oracle dialect now calls setinputsizes()
      with cx_Oracle.NCHAR unconditionally when the NVARCHAR2
      datatype, in SQLAlchemy corresponding to sqltypes.Unicode(), is
      in use. Per cx_Oracle’s author this allows the correct
      conversions to occur within the Oracle client regardless of the
      setting for NLS_NCHAR_CHARACTERSET.  References: #4163

Wed Jan 17 04:05:43 UTC 2018 -

- update to version 1.2.1:
  * orm
    + [orm] [bug] Fixed bug where an object that is expunged during a
      rollback of a nested or subtransaction which also had its
      primary key mutated would not be correctly removed from the
      session, causing subsequent issues in using the session.
    + [orm] [bug] Fixed regression where pickle format of a Load /
      _UnboundLoad object (e.g. loader options) changed and
      __setstate__() was raising an UnboundLocalError for an object
      received from the legacy format, even though an attempt was made
      to do so. tests are now added to ensure this works.
    + [orm] [bug] Fixed regression caused by new lazyload caching
      scheme in #3954 where a query that makes use of loader options
      with of_type would cause lazy loads of unrelated paths to fail
      with a TypeError.
    + [orm] [bug] Fixed bug in new “selectin” relationship loader
      where the loader could try to load a non-existent relationship
      when loading a collection of polymorphic objects, where only
      some of the mappers include that relationship, typically when
      PropComparator.of_type() is being used.
  * sql
    + [sql] [bug] Fixed bug in Insert.values() where using the
      “multi-values” format in combination with Column objects as keys
      rather than strings would fail. Pull request courtesy Aubrey
  * mssql
    + [mssql] [bug] Fixed regression in 1.2 where newly repaired
      quoting of collation names in #3785 breaks SQL Server, which
      explicitly does not understand a quoted collation name. Whether
      or not mixed-case collation names are quoted or not is now
      deferred down to a dialect-level decision so that each dialect
      can prepare these identifiers directly.
  * oracle
    + [oracle] [bug] Fixed regression where the removal of most
      setinputsizes rules from cx_Oracle dialect impacted the
      TIMESTAMP datatype’s ability to retrieve fractional seconds.
    + [oracle] [bug] Fixed regression in Oracle imports where a
      missing comma caused an undefined symbol to be present. Pull
      request courtesy Miroslav Shubernetskiy.
  * misc
    + [bug] [ext] Fixed regression in association proxy due to #3769
      (allow for chained any() / has()) where contains() against an
      association proxy chained in the form (o2m relationship,
      associationproxy(m2o relationship, m2o relationship)) would
      raise an error regarding the re-application of contains() on the
      final link of the chain.
    + [bug] [tests] Removed an oracle-specific requirements rule from
      the public test suite that was interfering with third party
      dialect suites.
    + [bug] [tests] Added a new exclusion rule
      group_by_complex_expression which disables tests that use “GROUP
      BY <expr>”, which seems to be not viable for at least two third
      party dialects.

- update to version 1.1.14:
  * orm
    + [orm] [bug] Fixed bug in Session.merge() following along similar
      lines as that of #4030, where an internal check for a target
      object in the identity map could lead to an error if it were to
      be garbage collected immediately before the merge routine
      actually retrieves the object. References: #4069
    + [orm] [bug] Fixed bug where an undefer_group() option would not
      be recognized if it extended from a relationship that was
      loading using joined eager loading. Additionally, as the bug led
      to excess work being performed, Python function call counts are
      also improved by 20% within the initial calculation of result
      set columns, complementing the joined eager load improvements of
      #3915.    References: #4048
    + [orm] [bug] Fixed race condition in ORM identity map which would
      cause objects to be inappropriately removed during a load
      operation, causing duplicate object identities to occur,
      particularly under joined eager loading which involves
      deduplication of objects. The issue is specific to garbage
      collection of weak references and is observed only under the
      Pypy interpreter.    References: #4068
    + [orm] [bug] Fixed bug in Session.merge() where objects in a
      collection that had the primary key attribute set to None for a
      key that is typically autoincrementing would be considered to be
      a database-persisted key for part of the internal deduplication
      process, causing only one object to actually be inserted in the
      database.    References: #4056
    + [orm] [bug] An InvalidRequestError is raised when a synonym() is
      used against an attribute that is not against a MapperProperty,
      such as an association proxy. Previously, a recursion overflow
      would occur trying to locate non-existent attributes.  References: #4067
  * sql
    + [sql] [bug] Altered the range specification for window functions
      to allow for two of the same PRECEDING or FOLLOWING keywords in
      a range by allowing for the left side of the range to be
      positive and for the right to be negative, e.g. (1, 3) is “1
      FOLLOWING AND 3 FOLLOWING”.    References: #4053

- changes from version 1.1.13:
  * oracle
    + [oracle] [bug] [py2k] [performance] Fixed performance regression
      caused by the fix for #3937 where cx_Oracle as of version 5.3
      dropped the .UNICODE symbol from its namespace, which was
      interpreted as cx_Oracle’s “WITH_UNICODE” mode being turned on
      unconditionally, which invokes functions on the SQLAlchemy side
      which convert all strings to unicode unconditionally and causing
      a performance impact. In fact, per cx_Oracle’s author the
      “WITH_UNICODE” mode has been removed entirely as of 5.1, so the
      expensive unicode conversion functions are no longer necessary
      and are disabled if cx_Oracle 5.1 or greater is detected under
      Python 2. The warning against “WITH_UNICODE” mode that was
      removed under #3937 is also restored.
      This change is also backported to: 1.0.19

  * orm
  + [bug] Fixed Session accounting bug whereby replacing
    a deleted object in the identity map with another
    object of the same primary key would raise a
    "conflicting state" error on rollback(),
    if the replaced primary key were established either
    via non-unitofwork-established INSERT statement
    or by primary key switch of another instance.
  * oracle
  + [bug] changed the list of cx_oracle types that are
    excluded from the setinputsizes() step to only include
    STRING and UNICODE; CLOB and NCLOB are removed.  This
    is to work around cx_oracle behavior which is broken
    for the executemany() call.  In 0.8, this same change 
    is applied however it is also configurable via the
    exclude_setinputsizes argument. [ticket:2561]

- update to 0.7.9:


  - [bug] Fixed bug mostly local to new AbstractConcreteBase helper
    where the "type" attribute from the superclass would not be overridden
    on the subclass to produce the "reserved for base" error message,
    instead placing a do-nothing attribute there. This was inconsistent
    vs. using ConcreteBase as well as all the behavior of classical
    concrete mappings, where the "type" column from the polymorphic base
    would be explicitly disabled on subclasses, unless overridden

  - [bug] A warning is emitted when lazy='dynamic' is combined with
    uselist=False. This is an exception raise in 0.8.

  - [bug] Fixed bug whereby user error in related-object assignment could
    cause recursion overflow if the assignment triggered a backref of the
    same name as a bi-directional attribute on the incorrect class to the
    same target. An informative error is raised now.

  - [bug] Fixed bug where incorrect type information would be passed when
    the ORM would bind the "version" column, when using the "version"
    feature. Tests courtesy Daniel Miller. [ticket:2539]

  - [bug] Extra logic has been added to the "flush" that occurs within
    Session.commit(), such that the extra state added by an after_flush()
    or after_flush_postexec() hook is also flushed in a subsequent flush,
    before the "commit" completes. Subsequent calls to flush() will
    continue until the after_flush hooks stop adding new state. An
    "overflow" counter of 100 is also in place, in the event of a broken
    after_flush() hook adding new content each time.  [ticket:2566] 


  - [feature] Dramatic improvement in memory usage of the event system;
    instance-level collections are no longer created for a particular type of
    event until instance-level listeners are established for that
    event. [ticket:2516] 

  - [bug] Fixed bug whereby a disconnect detect + dispose that occurs when
    the QueuePool has threads waiting for connections would leave those
    threads waiting for the duration of the timeout on the old pool (or
    indefinitely if timeout was disabled). The fix now notifies those
    waiters with a special exception case and has them move onto the new
    pool. [ticket:2522]

  - [bug] Added gaerdbms import to mysql/, the absense of which
    was preventing the new GAE dialect from being loaded. [ticket:2529]

  - [bug] Fixed cextension bug whereby the "ambiguous column error" would
    fail to function properly if the given index were a Column object and
    not a string. Note there are still some column-targeting issues here
    which are fixed in 0.8. [ticket:2553]

  - [bug] Fixed the repr() of Enum to include the "name" and "native_enum"
    flags. Helps Alembic autogenerate. 


  - [bug] Fixed the DropIndex construct to support an Index associated with
    a Table in a remote schema. [ticket:2571] 

  - [bug] Fixed bug in over() construct whereby passing an empty list for
    either partition_by or order_by, as opposed to None, would fail to
    generate correctly. Courtesy Gunnlaugur Þór Briem. [ticket:2574] 

  - [bug] Fixed CTE bug whereby positional bound parameters present in the
    CTEs themselves would corrupt the overall ordering of bound
    parameters. This primarily affected SQL Server as the platform with
    positional binds + CTE support. [ticket:2521] 

  - [bug] Fixed more un-intuitivenesses in CTEs which prevented referring
    to a CTE in a union of itself without it being aliased. CTEs now render
    uniquely on name, rendering the outermost CTE of a given name only -
    all other references are rendered just as the name. This even includes
    other CTE/SELECTs that refer to different versions of the same CTE
    object, such as a SELECT or a UNION ALL of that SELECT. We are somewhat
    loosening the usual link between object identity and lexical identity
    in this case. A true name conflict between two unrelated CTEs now
    raises an error. 

  - [bug] quoting is applied to the column names inside the WITH RECURSIVE
    clause of a common table expression according to the quoting rules for
    the originating Column. [ticket:2512] 

  - [bug] Fixed regression introduced in 0.7.6 whereby the FROM list of a
    SELECT statement could be incorrect in certain "clone+replace"
    scenarios. [ticket:2518] 

  - [bug] Fixed bug whereby usage of a UNION or similar inside of an
    embedded subquery would interfere with result-column targeting, in the
    case that a result-column had the same ultimate name as a name inside
    the embedded UNION. [ticket:2552] 

  - [bug] Fixed a regression since 0.6 regarding result-row targeting. It
    should be possible to use a select() statement with string based
    columns in it, that is select(['id', 'name']).select_from('mytable'),
    and have this statement be targetable by Column objects with those
    names; this is the mechanism by which
    query(MyClass).from_statement(some_statement) works. At some point the
    specific case of using select(['id']), which is equivalent to
    select([literal_column('id')]), stopped working here, so this has been
    re-instated and of course tested. [ticket:2558] 

  - [bug] Added missing operators is_(), isnot() to the ColumnOperators
    base, so that these long-available operators are present as methods
    like all the other operators. [ticket:2544] 


  - [bug] Columns in reflected primary key constraint are now returned in
    the order in which the constraint itself defines them, rather than how
    the table orders them. Courtesy Gunnlaugur Þór Briem.. [ticket:2531] 

  - [bug] Added 'terminating connection' to the list of messages we use to
    detect a disconnect with PG, which appears to be present in some
    versions when the server is restarted. [ticket:2570] 


  - [bug] Updated mysqlconnector interface to use updated "client flag" and
    "charset" APIs, courtesy David McNelis. 


  - [feature] Added support for the localtimestamp() SQL function
    implemented in SQLite, courtesy Richard Mitchell. 

  - [bug] Adjusted a very old bugfix which attempted to work around a
    SQLite issue that itself was "fixed" as of sqlite 3.6.14, regarding
    quotes surrounding a table name when using the "foreign_key_list"
    pragma. The fix has been adjusted to not interfere with quotes that are
    actually in the name of a column or table, to as much a degree as
    possible; sqlite still doesn't return the correct result for
    foreign_key_list() if the target table actually has quotes surrounding
    its name, as part of its name (i.e. """mytable"""). [ticket:2568] 

  - [bug] Adjusted column default reflection code to convert non-string
    values to string, to accommodate old SQLite versions that don't deliver
    default info as a string. [ticket:2265] 


  - [bug] Fixed compiler bug whereby using a correlated subquery within an
    ORDER BY would fail to render correctly if the stament also used
    LIMIT/OFFSET, due to mis-rendering within the ROW_NUMBER() OVER
    clause. Fix courtesy sayap [ticket:2538] 

  - [bug] Fixed compiler bug whereby a given select() would be modified if
    it had an "offset" attribute, causing the construct to not compile
    correctly a second time. [ticket:2545] 

  - [bug] Fixed bug where reflection of primary key constraint would double
    up columns if the same constraint/table existed in multiple schemas. 

- update to 0.7.8:


  - [feature] The 'objects' argument to flush() is no longer deprecated, as
    some valid use cases have been identified. 

  - [bug] Fixed bug whereby subqueryload() from a polymorphic mapping to a
    target would incur a new invocation of the query for each distinct
    class encountered in the polymorphic result. [ticket:2480] 

  - [bug] Fixed bug in declarative whereby the precedence of columns in a
    joined-table, composite column (typically for id) would fail to be
    correct if the columns contained names distinct from their attribute
    names. This would cause things like primaryjoin conditions made against
    the entity attributes to be incorrect. Related to as this was supposed
    to be part of that, this is. [ticket:2491, 1892] 

  - [bug] Fixed identity_key() function which was not accepting a scalar
    argument for the identity. . [ticket:2508] 

  - [bug] Fixed bug whereby populate_existing option would not propagate to
    subquery eager loaders. . [ticket:2497] 


  - [bug] Fixed memory leak in C version of result proxy whereby DBAPIs
    which don't deliver pure Python tuples for result rows would fail to
    decrement refcounts correctly. The most prominently affected DBAPI is
    pyodbc. [ticket:2489] 

  - [bug] Fixed bug affecting Py3K whereby string positional parameters
    passed to engine/connection execute() would fail to be interpreted
    correctly, due to __iter__ being present on Py3K string.. [ticket:2503] 


  - [bug] added BIGINT to types.__all__, BIGINT, BINARY, VARBINARY to
    sqlalchemy module namespace, plus test to ensure this breakage doesn't
    occur again. [ticket:2499] 

  - [bug] Repaired common table expression rendering to function correctly
    when the SELECT statement contains UNION or other compound expressions,
    courtesy btbuilder. [ticket:2490] 

  - [bug] Fixed bug whereby append_column() wouldn't function correctly on
    a cloned select() construct, courtesy Gunnlaugur Þór
    Briem. [ticket:2482] 


  - [bug] removed unnecessary table clause when reflecting enums,. Courtesy
    Gunnlaugur Þór Briem. [ticket:2510] 


  - [feature] Added a new dialect for Google App Engine. Courtesy Richie
    Foreman. [ticket:2484] 


  - [bug] Added ROWID to oracle.*. [ticket:2483]

Wed May 23 06:44:12 UTC 2012 -

- python3 package added 
- removed BuildRequires update-desktop-files, because there is no
  desktop files in package
- minor spec improvement 

Sun May  6 12:22:59 UTC 2012 -

- update to 0.7.7:
  * orm
  - [bug] Fixed issue in unit of work whereby setting a non-None 
    self-referential many-to-one relationship to None would fail 
    to persist the change if the former value was not already loaded.

  - [feature] Added prefix_with() method to Query, calls upon 
    select().prefix_with() to allow placement of MySQL SELECT
    directives in statements.  Courtesy Diana Clarke [ticket:2443]

  - [bug] Fixed bug in 0.7.6 introduced by [ticket:2409] whereby 
    column_mapped_collection used against columns that were mapped as
    joins or other indirect selectables would fail to function.

  - [feature] Added new flag to @validates include_removes. When True, 
    collection remove and attribute del events will also be sent to 
    the validation function, which accepts an additional argument
    "is_remove" when this flag is used.

  - [bug] Fixed bug whereby polymorphic_on column that's not otherwise 
    mapped on the class would be incorrectly included in a merge() 
    operation, raising an error. [ticket:2449]

  - [bug] Fixed bug in expression annotation mechanics which could 
    lead to incorrect rendering of SELECT statements with aliases
    and joins, particularly when using column_property(). [ticket:2453]

  - [bug] Fixed bug which would prevent OrderingList from being 
    pickleable [ticket:2454].  Courtesy Jeff Dairiki

  - [bug] Fixed bug in relationship comparisons whereby calling 
    unimplemented methods like 
    would produce a recursion overflow, instead of NotImplementedError.

  * sql
  - [bug] Removed warning when Index is created with no columns;  
    while this might not be what the user intended, it is a valid use case 
    as an Index could be a placeholder for just an index of a certain name.

  - [feature] Added new connection event dbapi_error(). Is called for 
    all DBAPI-level errors passing the original DBAPI exception before 
    SQLAlchemy modifies the state of the cursor. "with engine.begin()", 
    the newly acquired Connection is closed explicitly before propagating 
    the exception onward normally.

  - [bug] Add BINARY, VARBINARY to types.__all__, [ticket:2474]

  * mssql
  - [feature] Added interim create_engine flag supports_unicode_binds 
    to PyODBC dialect, to force whether or not the dialect passes 
    Python unicode literals to PyODBC or not.

  - [bug] Repaired the use_scope_identity create_engine() flag when 
    using the pyodbc dialect. Previously this flag would be ignored if 
    set to False.  When set to False, you'll get "SELECT @@identity" 
    after each INSERT to get at the last inserted ID, for those tables 
    which have "implicit_returning" set to False.
  - [bug] UPDATE..FROM syntax with SQL Server requires that the updated 
    table be present in the FROM clause when an alias of that table is 
    also present in the FROM clause. The updated table is now always present
    in the FROM, when FROM is present in the first place.  Courtesy sayap.

  * postgresql
  - [feature] Added new for_update/with_lockmode() options for Postgresql: 
    for_update="read"/ with_lockmode("read"), for_update="read_nowait"/
    with_lockmode("read_nowait"). These emit "FOR SHARE" and "FOR SHARE 
    NOWAIT", respectively.  Courtesy Diana Clarke [ticket:2445]

  - [bug] removed unnecessary table clause when reflecting domains, [ticket:2473]

  * mysql
  - [bug] Fixed bug whereby column name inside of "KEY" clause for autoincrement 
    composite column with InnoDB would double quote a name that's a reserved 
    word.  Courtesy Jeff Dairiki. [ticket:2460]

  - [bug] Fixed bug whereby get_view_names() for "information_schema" schema 
    would fail to retrieve views marked as "SYSTEM VIEW". courtesy Matthew Turland.

  - [bug] Fixed bug whereby if cast() is used on a SQL expression whose type 
    is not supported by cast() and therefore CAST isn't rendered by the 
    dialect, the order of evaluation could change if the casted expression 
    required that it be grouped; grouping is now applied to those expressions.

  * sqlite
  - [feature] Added SQLite execution option "sqlite_raw_colnames=True", will 
    bypass attempts to remove "." from column names returned by SQLite 
    cursor.description. [ticket:2475]

Mon Apr 30 09:13:02 UTC 2012 -

- Update to 0.7.6
 * orm
  - [bug] Fixed event registration bug
    which would primarily show up as
    events not being registered with 
    sessionmaker() instances created
    after the event was associated
    with the Session class.  [ticket:2424]

  - [bug] Fixed bug whereby a primaryjoin
    condition with a "literal" in it would
    raise an error on compile with certain
    kinds of deeply nested expressions
    which also needed to render the same
    bound parameter name more than once.

  - [feature] Added "no_autoflush" context
    manager to Session, used with with:
    will temporarily disable autoflush.

  - [feature] Added cte() method to Query,
    invokes common table expression support
    from the Core (see below). [ticket:1859]

  - [bug] Removed the check for number of
    rows affected when doing a multi-delete
    against mapped objects.   If an ON DELETE
    CASCADE exists between two rows, we can't
    get an accurate rowcount from the DBAPI;
    this particular count is not supported
    on most DBAPIs in any case, MySQLdb
    is the notable case where it is.

  - [bug] Fixed bug whereby objects using
    attribute_mapped_collection or 
    column_mapped_collection could not be
    pickled.  [ticket:2409]

  - [bug] Fixed bug whereby MappedCollection
    would not get the appropriate collection
    instrumentation if it were only used
    in a custom subclass that used

  - [bug] Fixed bug whereby SQL adaption mechanics
    would fail in a very nested scenario involving
    joined-inheritance, joinedload(), limit(), and a
    derived function in the columns clause.  

  - [bug] Fixed the repr() for CascadeOptions to
    include refresh-expire.  Also reworked
    CascadeOptions to be a <frozenset>.

  - [feature] Added the ability to query for
    Table-bound column names when using 

  - [bug] Improved the "declarative reflection" 
    example to support single-table inheritance,
    multiple calls to prepare(), tables that
    are present in alternate schemas,
    establishing only a subset of classes
    as reflected.

  - [bug] Scaled back the test applied within
    flush() to check for UPDATE against partially 
    NULL PK within one table to only actually 
    happen if there's really an UPDATE to occur.

  - [bug] Fixed bug whereby if a method name
    conflicted with a column name, a
    TypeError would be raised when the mapper
    tried to inspect the __get__() method
    on the method object.  [ticket:2352]

 * sql
  - [bug] Fixed memory leak in core which would
    occur when C extensions were used with
    particular types of result fetches,
    in particular when orm query.count()
    were called.  [ticket:2427]

  - [bug] Fixed issue whereby attribute-based
    column access on a row would raise 
    AttributeError with non-C version,
    NoSuchColumnError with C version.  Now
    raises AttributeError in both cases.

  - [feature] Added support for SQL standard
    common table expressions (CTE), allowing
    SELECT objects as the CTE source (DML
    not yet supported).  This is invoked via
    the cte() method on any select() construct.

  - [bug] Added support for using the .key
    of a Column as a string identifier in a 
    result set row.   The .key is currently
    listed as an "alternate" name for a column,
    and is superseded by the name of a column 
    which has that key value as its regular name.
    For the next major release
    of SQLAlchemy we may reverse this precedence
    so that .key takes precedence, but this
    is not decided on yet.  [ticket:2392]

  - [bug] A warning is emitted when a not-present
    column is stated in the values() clause
    of an insert() or update() construct.
    Will move to an exception in 0.8.

  - [bug] A significant change to how labeling
    is applied to columns in SELECT statements
    allows "truncated" labels, that is label names
    that are generated in Python which exceed
    the maximum identifier length (note this is 
    configurable via label_length on create_engine()),
    to be properly referenced when rendered inside
    of a subquery, as well as to be present
    in a result set row using their original
    in-Python names.   [ticket:2396]

  - [bug] Fixed bug in new "autoload_replace" flag
    which would fail to preserve the primary
    key constraint of the reflected table.

  - [bug] Index will raise when arguments passed
    cannot be interpreted as columns or expressions.
    Will warn when Index is created
    with no columns at all.  [ticket:2380]

 * engine
  - [feature] Added "no_parameters=True" execution
    option for connections.   If no parameters
    are present, will pass the statement
    as cursor.execute(statement), thereby invoking
    the DBAPIs behavior when no parameter collection
    is present; for psycopg2 and mysql-python, this
    means not interpreting % signs in the string.
    This only occurs with this option, and not
    just if the param list is blank, as otherwise
    this would produce inconsistent behavior
    of SQL expressions that normally escape percent
    signs (and while compiling, can't know ahead of 
    time if parameters will be present in 
    some cases).  [ticket:2407]

  - [bug] Added execution_options() call to
    MockConnection (i.e., that used with 
    strategy="mock") which acts as a pass through
    for arguments.

  - [feature] Added pool_reset_on_return argument
    to create_engine, allows control over 
    "connection return" behavior.  Also added
    new arguments 'rollback', 'commit', None
    to pool.reset_on_return to allow more control
    over connection return activity. [ticket:2378]

  - [feature] Added some decent context managers
    to Engine, Connection:

        with engine.begin() as conn:
            <work with conn in a transaction>


        with engine.connect() as conn:
            <work with conn>

    Both close out the connection when done,
    commit or rollback transaction with errors
    on engine.begin().

 * sqlite
  - [bug] Fixed bug in C extensions whereby
    string format would not be applied to a
    Numeric value returned as integer; this
    affected primarily SQLite which does
    not maintain numeric scale settings.

 * mssql
  - [feature] Added support for MSSQL INSERT, 
    UPDATE, and DELETE table hints, using
    new with_hint() method on UpdateBase.

 * mysql
  - [feature] Added support for MySQL index and
    primary key constraint types
    (i.e. USING) via new mysql_using parameter
    to Index and PrimaryKeyConstraint, 
    courtesy Diana Clarke.  [ticket:2386]

  - [feature] Added support for the "isolation_level"
    parameter to all MySQL dialects.  Thanks
    to mu_mind for the patch here. [ticket:2394]

 * oracle
  - [feature] Added a new create_engine() flag
    coerce_to_decimal=False, disables the precision
    numeric handling which can add lots of overhead
    by converting all numeric values to 
    Decimal.  [ticket:2399]

  - [bug] Added missing compilation support for 
    LONG [ticket:2401]

  - [bug] Added 'LEVEL' to the list of reserved
    words for Oracle.  [ticket:2435]

 * examples
  - [bug] Altered _params_from_query() function
    in Beaker example to pull bindparams from the
    fully compiled statement, as a quick means
    to get everything including subqueries in the
    columns clause, etc. 

Wed Feb 22 12:36:45 UTC 2012 -

- Fixed SLE_11 build by disabling the testsuite for it

Thu Feb  9 09:39:26 UTC 2012 -

- Update to 0.7.5:

    transaction that begins automatically after manual call to
  * Improved the API for add_column() such that if the same column
    is added to its own table, an error is not raised and the
    constraints don't get doubled up.
  * Fixed issue where the "required" exception would not be raised
    for bindparam() with required=True, if the statement were given
    no parameters at all.
  * for more details see the CHANGES file.
