Other tricks are sure to +come later regarding SQLSession. +- added nest_on argument to objectstore.Session. This is a single SQLEngine or +list of engines for which push_session()/pop_session() will be called each time +this Session becomes the active session (via objectstore.push_session() or +equivalent). This allows a unit of work Session to take advantage of the nested +transaction feature without explicitly calling push_session/pop_session on the +engine. +- factored apart objectstore/unitofwork to separate "Session scoping" from +"uow commit heavy lifting" +- added populate_instance() method to MapperExtension. allows an extension to +modify the population of object attributes. this method can call the +populate_instance() method on another mapper to proxy the attribute population +from one mapper to another; some row translation logic is also built in to help +with this. +- fixed Oracle8-compatibility "use_ansi" flag which converts JOINs to +comparisons with the = and (+) operators, passes basic unittests +- tweaks to Oracle LIMIT/OFFSET support +- Oracle reflection uses ALL_** views instead of USER_** to get larger +list of stuff to reflect from +- fixes to Oracle foreign key reflection [ticket:105] +- objectstore.commit(obj1, obj2,...) adds an extra step to seek out private +relations on properties and delete child objects, even though its not a global +commit +- lots and lots of fixes to mappers which use inheritance, strengthened the +concept of relations on a mapper being made towards the "local" table for that +mapper, not the tables it inherits. allows more complex compositional patterns +to work with lazy/eager loading. +- some minor speed improvements to the attributes system with regards to +instantiating and populating new objects. +- fixed MySQL binary unit test +- INSERTs can receive clause elements as VALUES arguments, not just literal +values +- support for calling multi-tokened functions, i.e. schema.mypkg.func() +- added J. Ellis' SQLSoup module to extensions package +- added "polymorphic" examples illustrating methods to load multiple object types +from one mapper, the second of which uses the new populate_instance() method. +small improvements to mapper, UNION construct to help the examples along +- improvements/fixes to session.refresh()/session.expire() (which may have +been called "invalidate" earlier..) +- added session.expunge() which totally removes an object from the current +session +- added *args, **kwargs pass-thru to engine.transaction(func) allowing easier +creation of transactionalizing decorator functions +- added iterator interface to ResultProxy: "for row in result:..." +- added assertion to tx = session.begin(); tx.rollback(); tx.begin(), i.e. cant +use it after a rollback() +- added date conversion on bind parameter fix to SQLite enabling dates to +work with pysqlite1 +- improvements to subqueries to more intelligently construct their FROM +clauses [ticket:116] + +- added PickleType to types. +- fixed two bugs with column labels with regards to bind parameters: bind param +keynames they are now generated from a column "label" in all relevant cases to +take advantage of excess-name-length rules, and checks for a peculiar collision +against a column named the same as "tablename_colname" added +- major overhaul to unit of work documentation, other documentation sections. </ins><span class="cx"> - fixed attributes bug where if an object is committed, its lazy-loaded list got </span><span class="cx"> blown away if it hadnt been loaded </span><del>-- added unique_connection() method to engine, connection pool to return a connection -that is not part of the thread-local context or any current transaction -- added distinct() function to column elements so you can do func.count(mycol.distinct()) </del><ins>+- added unique_connection() method to engine, connection pool to return a +connection that is not part of the thread-local context or any current +transaction +- added invalidate() function to pooled connection. will remove the connection +from the pool. still need work for engines to auto-reconnect to a stale DB +though. +- added distinct() function to column elements so you can do +func.count(mycol.distinct()) +- added "always_refresh" flag to Mapper, creates a mapper that will always +refresh the attributes of objects it gets/selects from the DB, overwriting any +changes made. </ins><span class="cx"> </span><span class="cx"> 0.1.4 </span><del>-- create_engine() now uses genericized parameters;
