Changelog for python-SQLAlchemy-1.2.14-2.12.x86_64.rpm :
Mon Nov 12 13:00:00 2018 Arun Persaud
- 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 13:00:00 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
+ [postgresql] [bug] Added support for the aggregate_order_by
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
for MySQL, which is now a keyword in MySQL 8.0 References: #4348
+ [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
courtesy Joe Urciuoli.
+ [misc] [bug] [py3k] Fixed additional warnings generated by
Python 3.7 due to changes in the organization of the Python
collections and collections.abc packages. Previous collections
warnings were fixed in version 1.2.11. Pull request courtesy
xtreak. References: #4339
+ [bug] [ext] Added missing .index() method to list-based
association collections in the association proxy extension.

Sat Sep 22 14:00:00 2018 Arun Persaud
- update to version 1.2.12:

* orm
+ [orm] [bug] Added a check within the weakref cleanup for the
InstanceState object to check for the presence of the dict
builtin, in an effort to reduce error messages generated when
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
post-update operation would also occur for a row that is to be
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

* orm declarative
+ [bug] [declarative] [orm] Fixed bug where the declarative scan
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
AATTdeclared_attr callable on a subclass of an already-mapped
class. This would lead to an attribute that did not report
itself as a hybrid when viewed within
Mapper.all_orm_descriptors. References: #4326

* postgresql
+ [postgresql] [bug] Fixed bug in PostgreSQL dialect where
compiler keyword arguments such as literal_binds=True were not
being propagated to a DISTINCT ON expression. References: #4325
+ [postgresql] [bug] Fixed the postgresql.array_agg() function,
which is a slightly altered version of the usual
functions.array_agg() function, to also accept an incoming
“type” argument without forcing an ARRAY around it, essentially
the same thing that was fixed for the generic function in 1.1 in
[#4107]. References: #4324
+ [postgresql] [bug] Fixed bug in PostgreSQL ENUM reflection where
a case-sensitive, quoted name would be reported by the query
including quotes, which would not match a target column during
table reflection as the quotes needed to be stripped off.
References: #4323

* oracle
+ [oracle] [bug] Fixed issue for cx_Oracle 7.0 where the behavior
of Oracle param.getvalue() now returns a list, rather than a
single scalar value, breaking autoincrement logic throughout the
Core and ORM. The dml_ret_array_val compatibility flag is used
for cx_Oracle 6.3 and 6.4 to establish compatible behavior with
7.0 and forward, for cx_Oracle 6.2.1 and prior a version number
check falls back to the old logic. References: #4335

* misc
+ [bug] [ext] Fixed issue where BakedQuery did not include the
specific query class used by the Session as part of the cache
key, leading to incompatibilities when using custom query
classes, in particular the ShardedQuery which has some different
argument signatures. References: #4328

Sat Aug 25 14:00:00 2018 arunAATTgmx.de
- update to version 1.2.11:

* 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

* sql
+ [sql] [bug] Fixed issue that is closely related to #3639 where
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
within the compliation of the statement. References: #4320
+ [sql] [bug] Added missing window function parameters
WithinGroup.over.range_ and WithinGroup.over.rows parameters to
the WithinGroup.over() and FunctionFilter.over() methods, to
correspond to the range/rows feature added to the “over” method
of SQL functions as part of #3049 in version 1.1. References:
[#4322]
+ [sql] [bug] Fixed bug where the multi-table support for UPDATE
and DELETE statements did not consider the additional FROM
elements as targets for correlation, when a correlated SELECT
were also combined with the statement. This change now includes
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;
specify Select.correlate() explicitly to resolve. References:
[#4313]

* oracle
+ [oracle] [bug] For cx_Oracle, Integer datatypes will now be
bound to “int”, per advice from the cx_Oracle
developers. Previously, using cx_Oracle.NUMBER caused a loss in
precision within the cx_Oracle 6.x series. References: #4309

* misc
+ [bug] [py3k] Started importing “collections” from
“collections.abc” under Python 3.3 and greater for Python 3.8
compatibility. Pull request courtesy Nathaniel Knight.
+ Fixed issue where the “schema” name used for a SQLite database
within table reflection would not quote the schema name
correctly. Pull request courtesy Phillip Cloud.

Sat Jul 14 14:00:00 2018 arunAATTgmx.de
- update to version 1.2.10:

* orm
+ [orm] [bug] Fixed bug in Bundle construct where placing two
columns of the same name would be de-duplicated, when the Bundle
were used as part of the rendered SQL, such as in the ORDER BY
or GROUP BY of the statement. References: #4295
+ [orm] [bug] Fixed regression in 1.2.9 due to #4287 where using a
Load option in conjunction with a string wildcard would result
in a TypeError. References: #4298

* sql
+ [sql] [bug] Fixed bug where a Sequence would be dropped
explicitly before any Table that refers to it, which breaks in
the case when the sequence is also involved in a server-side
default for that table, when using MetaData.drop_all(). The step
which processes sequences to be dropped via non server-side
column default functions is now invoked after the table itself
is dropped. References: #4300

Sun Jul 1 14:00:00 2018 arunAATTgmx.de
- removed patch fix_test_reflection.patch (included upstream)
- update to version 1.2.9:

* orm
+ [orm] [bug] Fixed issue where chaining multiple join elements
inside of Query.join() might not correctly adapt to the previous
left-hand side, when chaining joined inheritance classes that
share the same base class.
References: #3505
+ [orm] [bug] Fixed bug in cache key generation for baked queries
which could cause a too-short cache key to be generated for the
case of eager loads across subclasses. This could in turn cause
the eagerload query to be cached in place of a non-eagerload
query, or vice versa, for a polymorhic “selectin” load, or
possibly for lazy loads or selectin loads as well.
References: #4287
+ [orm] [bug] Fixed bug in new polymorphic selectin loading where
the BakedQuery used internally would be mutated by the given
loader options, which would both inappropriately mutate the
subclass query as well as carry over the effect to subsequent
queries.
References: #4286
+ [orm] [bug] Fixed regression caused by #4256 (itself a
regression fix for #4228) which breaks an undocumented behavior
which converted for a non-sequence of entities passed directly
to the Query constructor into a single-element sequence. While
this behavior was never supported or documented, it’s already in
use so has been added as a behavioral contract to Query.
References: #4269
+ [orm] [bug] Fixed an issue that was both a performance
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.
References: #4270

* sql
+ [sql] [bug] Fixed regression in 1.2 due to #4147 where a Table
that has had some of its indexed columns redefined with new
ones, as would occur when overriding columns during reflection
or when using Table.extend_existing, such that the
Table.tometadata() method would fail when attempting to copy
those indexes as they still referred to the replaced column. The
copy logic now accommodates for this condition.
References: #4279

* mysql
+ [mysql] [bug] Fixed percent-sign doubling in
mysql-connector-python dialect, which does not require
de-doubling of percent signs. Additionally, the mysql-
connector-python driver is inconsistent in how it passes the
column names in cursor.description, so a workaround decoder has
been added to conditionally decode these
randomly-sometimes-bytes values to unicode only if needed. Also
improved test support for mysql-connector-python, however it
should be noted that this driver still has issues with unicode
that continue to be unresolved as of yet.
+ [mysql] [bug] Fixed bug in index reflection where on MySQL 8.0
an index that includes ASC or DESC in an indexed column
specfication would not be correctly reflected, as MySQL 8.0
introduces support for returning this information in a table
definition string.
References: #4293
+ [mysql] [bug] Fixed bug in MySQLdb dialect and variants such as
PyMySQL where an additional “unicode returns” check upon
connection makes explicit use of the “utf8” character set, which
in MySQL 8.0 emits a warning that utf8mb4 should be used. This
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
issues in some edge cases with utf8mb4), and to support
configuration default changes made in MySQL 8.0 such as
explicit_defaults_for_timestamp as well as new errors raised for
invalid MyISAM indexes.
References: #4283
+ [mysql] [bug] The Update construct now accommodates a Join
object as supported by MySQL for UPDATE..FROM. As the construct
already accepted an alias object for a similar purpose, the
feature of UPDATE against a non-table was already implied so
this has been added.
References: #3645

* sqlite
+ [sqlite] [bug] Fixed issue in test suite where SQLite 3.24 added
a new reserved word that conflicted with a usage in
TypeReflectionTest. Pull request courtesy Nils Philippsen.

* mssql
+ [mssql] [bug] Fixed bug in MSSQL reflection where when two
same-named tables in different schemas had same-named primary
key constraints, foreign key constraints referring to one of the
tables would have their columns doubled, causing errors. Pull
request courtesy Sean Dunn.
References: #4228
+ [mssql] [bug] [py3k] Fixed issue within the SQL Server dialect
under Python 3 where when running against a non-standard SQL
server database that does not contain either the
“sys.dm_exec_sessions” or “sys.dm_pdw_nodes_exec_sessions”
views, leading to a failure to fetch the isolation level, the
error raise would fail due to an UnboundLocalError.
References: #4273

* oracle
+ [oracle] [feature] Added a new event currently used only by the
cx_Oracle dialect, DialectEvents.setiputsizes(). The event
passes a dictionary of BindParameter objects to DBAPI-specific
type objects that will be passed, after conversion to parameter
names, to the cx_Oracle cursor.setinputsizes() method. This
allows both visibility into the setinputsizes process as well as
the ability to alter the behavior of what datatypes are passed
to this method.
See als Fine grained control over cx_Oracle data binding and performance with setinputsizes
References: #4290
+ [oracle] [bug] [mysql] Fixed INSERT FROM SELECT with CTEs for
the Oracle and MySQL dialects, where the CTE was being placed
above the entire statement as is typical with other databases,
however Oracle and MariaDB 10.2 wants the CTE underneath the
“INSERT” segment. Note that the Oracle and MySQL dialects don’t
yet work when a CTE is applied to a subquery inside of an UPDATE
or DELETE statement, as the CTE is still applied to the top
rather than inside the subquery.
References: #4275

* misc
+ [feature] [ext] Added new attribute Query.lazy_loaded_from which
is populated with an InstanceState that is using this Query in
order to lazy load a relationship. The rationale for this is
that it serves as a hint for the horizontal sharding feature to
use, such that the identity token of the state can be used as
the default identity token to use for the query within
id_chooser().
References: #4243
+ [bug] [py3k] Replaced the usage of inspect.formatargspec() with
a vendored version copied from the Python standard library, as
inspect.formatargspec() is deprecated and as of Python 3.7.0 is
emitting a warning.
References: #4291

Tue Jun 26 14:00:00 2018 mimi.vxAATTgmail.com
- add upstream fix_test_reflection.patch to fix tests with new sqlite

Thu Jun 21 14:00:00 2018 hpjAATTurpla.net
- 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.
References: #4258

* 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
the parameter dictionary used in a statement execution would
remain referenced by the “compiled cache”, as a result of
storing the key view used by Python 3 dictionary keys(). Pull
request courtesy Olivier Grisel.

* sql
+ [sql] [bug] Fixed issue where the “ambiguous literal” error
message used when interpreting literal values as SQL expression
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
”. 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.
References: #4247
+ [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
+ [bug] [tests] Fixed a bug in the test suite where if an
external dialect returned None for server_version_info, the
exclusion logic would raise an AttributeError.
References: #4249

Sat Apr 21 14:00:00 2018 arunAATTgmx.de
- update to version 1.2.7:

* orm
+ [orm] [bug] Fixed regression in 1.2 within sharded query feature
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
should be noted for other derivations of this class.
References: #4228
+ [orm] [bug] Fixed issue in single-inheritance loading where the
use of an aliased entity against a single-inheritance subclass
in conjunction with the Query.select_from() method would cause
the SQL to be rendered with the unaliased table mixed in to the
query, causing a cartesian product. In particular this was
affecting the new “selectin” loader when used against a
single-inheritance subclass. References: #4241

* sql
+ [sql] [bug] Fixed issue where the compilation of an INSERT
statement with the “literal_binds” option that also uses an
explicit sequence and “inline” generation, as on Postgresql and
Oracle, would fail to accommodate the extra keyword argument
within the sequence processing routine. References: #4231

* postgresql
+ [postgresql] [feature] Added new PG type postgresql.REGCLASS
which assists in casting table names to OID values. Pull request
courtesy Sebastian Bank. References: #4160
+ [postgresql] [bug] Fixed bug where the special “not equals”
operator for the Postgresql “range” datatypes such as DATERANGE
would fail to render “IS NOT NULL” when compared to the Python
None value. References: #4229

* mssql
+ [mssql] [bug] Fixed 1.2 regression caused by #4060 where the
query used to reflect SQL Server cross-schema foreign keys was
limiting the criteria incorrectly. References: #4234

* oracle
+ [oracle] [bug] The Oracle NUMBER datatype is reflected as
INTEGER if the precision is NULL and the scale is zero, as this
is how INTEGER values come back when reflected from Oracle’s
tables. Pull request courtesy Kent Bower.

Sun Apr 1 14:00:00 2018 arunAATTgmx.de
- specfile:

* run spec-cleaner
- update to version 1.2.6:

* orm
+ [orm] [bug] Fixed bug where using Mutable.associate_with() or
Mutable.as_mutable() in conjunction with a class that has non-
primary mappers set up with alternatively-named attributes would
produce an attribute error. Since non-primary mappers are not
used for persistence, the mutable extension now excludes
non-primary mappers from its instrumentation steps. References:
[#4215]

* engine
+ [engine] [bug] Fixed bug in connection pool where a connection
could be present in the pool without all of its “connect” event
handlers called, if a previous “connect” handler threw an
exception; note that the dialects themselves have connect
handlers that emit SQL, such as those which set transaction
isolation, which can fail if the database is in a non-available
state, but still allows a connection. The connection is now
invalidated first if any of the connect handlers fail.
References: #4225

* sql
+ [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
Solovyov.

* 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
AATTdeclared_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.

+ [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 AATTAATTversion 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 13:00:00 2018 arunAATTgmx.de
- 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 13:00:00 2018 arunAATTgmx.de
- 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
Robin.

* 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 13:00:00 2018 arunAATTgmx.de
- 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
Magliocchetti.

* 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 13:00:00 2018 arunAATTgmx.de
- 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
Stark-Toller.

* 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 ”, which seems to be not viable for at least two third
party dialects.

Mon Sep 25 14:00:00 2017 arunAATTgmx.de
- 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.
[ticket:2583]

* 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]

* mysql
+ [feature] Added \"raise_on_warnings\" flag to OurSQL
dialect. [ticket:2523]
+ [feature] Added \"read_timeout\" flag to MySQLdb
dialect. [ticket:2554]

- do not require python-pysqlite package.
- update to 0.7.9:

* orm
- [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
explicitly.
- [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]

* engine
- [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/__init__.py, 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.

* sql
- [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]

* postgresql
- [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]

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

* sqlite
- [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]

* mssql
- [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:

* orm
- [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]

* engine
- [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]

* sql
- [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]

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

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

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

Wed May 23 14:00:00 2012 highwaystar.ruAATTgmail.com
- python3 package added
- removed BuildRequires update-desktop-files, because there is no
desktop files in package
- minor spec improvement

Sun May 6 14:00:00 2012 larsAATTlinux-schulserver.de
- 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.
[ticket:2477].
- [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 AATTvalidates 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 SomeClass.somerelationship.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 AATTAATTidentity\"
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.
[ticket:2468]

* 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 14:00:00 2012 cfarrellAATTsuse.com
- 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.
[ticket:2425]
- [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.
[ticket:2403]
- [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
AATTcollection.internally_instrumented.
[ticket:2406]
- [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.
[ticket:2419]
- [bug] Fixed the repr() for CascadeOptions to
include refresh-expire. Also reworked
CascadeOptions to be a .
[ticket:2417]
- [feature] Added the ability to query for
Table-bound column names when using
query(sometable).filter_by(colname=value).
[ticket:2400]
- [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.
[ticket:2390]
- [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.
[ticket:2398]
- [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.
[ticket:1859]
- [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.
[ticket:2413]
- [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.
[ticket:2402]
- [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:

and:
with engine.connect() as 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.
[ticket:2432]

* mssql
- [feature] Added support for MSSQL INSERT,
UPDATE, and DELETE table hints, using
new with_hint() method on UpdateBase.
[ticket:2430]

* 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 13:00:00 2012 saschpeAATTsuse.de
- Fixed SLE_11 build by disabling the testsuite for it

Thu Feb 9 13:00:00 2012 rhaferAATTsuse.de
- Update to 0.7.5:

* Fixed issue where modified session state established after a
failed flush would be committed as part of the subsequent
transaction that begins automatically after manual call to
rollback().

* 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.
