------------------------------------------------------------------- Thu Oct 15 12:35:15 UTC 2020 - Johannes Grassler <johannes.grassler@suse.com> - Add 0002-maintain-compiled_params-replacement_expressions.patch (bsc#1176953) * Maintain compiled_params / replacement_expressions within expanding IN ------------------------------------------------------------------- Tue Aug 20 11:25:21 UTC 2019 - Ralf Haferkamp <rhafer@suse.com> - Add 0001-Illustrate-fix-for-4481-in-terms-of-a-1.2-patch.patch (bsc#1124593, CVE-2019-7164, CVE-2019-7548) ------------------------------------------------------------------- Mon Nov 12 06:16:33 UTC 2018 - Arun Persaud <arun@gmx.de> - 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 <arun@gmx.de> - 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 05:28:52 UTC 2018 - Arun Persaud <arun@gmx.de> - 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 @declared_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 18:12:02 UTC 2018 - arun@gmx.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 01:56:32 UTC 2018 - arun@gmx.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 02:17:55 UTC 2018 - arun@gmx.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 06:55:57 UTC 2018 - mimi.vx@gmail.com - add upstream fix_test_reflection.patch to fix tests with new sqlite ------------------------------------------------------------------- Thu Jun 21 23:01:18 UTC 2018 - hpj@urpla.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 <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. 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 16:35:48 UTC 2018 - arun@gmx.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 22:17:46 UTC 2018 - arun@gmx.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 @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. References: #4221 ------------------------------------------------------------------- Thu Mar 8 04:50:46 UTC 2018 - arun@gmx.de - 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 - arun@gmx.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 17:09:28 UTC 2018 - arun@gmx.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.

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: #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.

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 <expr>”, which seems to be not viable for at least two third party dialects. ------------------------------------------------------------------- Wed Jan 3 03:57:00 UTC 2018 - arun@gmx.de - specfile: * updated test requirements ------------------------------------------------------------------- Sun Dec 31 05:58:02 UTC 2017 - arun@gmx.de - update to version 1.2.0: * See https://docs.sqlalchemy.org/en/latest/changelog/changelog_12.html ------------------------------------------------------------------- Mon Sep 25 16:11:55 UTC 2017 - arun@gmx.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.

[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.

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 06:44:12 UTC 2012 - highwaystar.ru@gmail.com - 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 - lars@linux-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 @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 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 @@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. [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 09:13:02 UTC 2012 - cfarrell@suse.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 @collection.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 <frozenset>. [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: <work with conn in a transaction> and: 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. [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 12:36:45 UTC 2012 - saschpe@suse.de - Fixed SLE_11 build by disabling the testsuite for it ------------------------------------------------------------------- Thu Feb 9 09:39:26 UTC 2012 - rhafer@suse.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. ------------------------------------------------------------------- Thu Nov 10 10:56:36 UTC 2011 - saschpe@suse.de - Add depenendency on pysqlite ------------------------------------------------------------------- Wed Sep 21 11:51:17 UTC 2011 - saschpe@suse.de - Update to version 0.7.2: * A rework of "replacement traversal" * Fixed bug where query.join() + aliased=True * Fixed regression from 0.6 where Session.add() against an object which contained None - See CHANGES for more... - Run testsuite ------------------------------------------------------------------- Wed Jul 20 17:42:11 UTC 2011 - saschpe@gmx.de - Let doc package require base package instead of recommends ------------------------------------------------------------------- Wed Jul 20 17:23:11 UTC 2011 - saschpe@gmx.de - Dropped unused BuildRequires for fdupes and python-sqlite2 ------------------------------------------------------------------- Wed Jul 20 16:59:39 UTC 2011 - saschpe@gmx.de - Initial version, replaces python-sqlalchemy * Much simpler spec file * Packaged LICENSE, CHANGES and README files
