------------------------------------------------------------------- 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
