| | | | | | | | | | | | | 220/skip tests - Fixed potential memory leak which could occur if an arbitrary number of :class:`.sessionmaker` objects were created. The anonymous subclass created by the sessionmaker, when dereferenced, would not be garbage collected due to remaining class-level references from the event package. This issue also applies to any custom system that made use of ad-hoc subclasses in conjunction with an event dispatcher. Also in 0.7.10. [ticket:2650]

| | | | | | | | | | | :meth:`.MutableBase.coerce` method to be used, even though the code seemed to indicate this intent, so this now works and a brief example is added. As a side-effect, the mechanics of this event handler have been changed so that new :class:`.MutableComposite` types no longer add per-type global event handlers. Also in 0.7.10 [ticket:2624]

* - [feature] Improvements to event listening forMike Bayer2012-10-121-4/+7
| | | | | | | | | | | | | | | | | | | mapped classes allows that unmapped classes can be specified for instance- and mapper-events. The established events will be automatically set up on subclasses of that class when the propagate=True flag is passed, and the events will be set up for that class itself if and when it is ultimately mapped. [ticket:2585] - [bug] The instrumentation events class_instrument(), class_uninstrument(), and attribute_instrument() will now fire off only for descendant classes of the class assigned to listen(). Previously, an event listener would be assigned to listen for all classes in all cases regardless of the "target" argument passed. [ticket:2590]

* - [bug] Fixed event registration bugMike Bayer2012-03-071-9/+26

* - rename EngineEvents to ConnectionEventsMike Bayer2011-02-171-6/+3
| | | | | | | | - simplify connection event model to be inline inside Connection, don't use ad-hoc subclasses (technically would leak memory for the app that keeps creating engines and adding events) - not doing listen-per-connection yet. this is closer. overall things are much simpler now (until we put listen-per-connection in...)
* - SchemaItem, SchemaType now descend from common typeMike Bayer2011-01-301-3/+13
| | | | | | | | | | | | | | | | | | SchemaEventTarget, which supplies dispatch - the dispatch now provides before_parent_attach(), after_parent_attach(), events which generally bound the _set_parent() event. [ticket:2037] - the _on_table_attach mechanism now usually uses the event dispatch - fixed class-level event dispatch to propagate to all subclasses, not just immediate subclasses - fixed class-level event unpickling to handle more involved inheritance hierarchies, needed by the new schema event dispatch. - ForeignKeyConstraint doesn't re-call the column attach event on ForeignKey objects that are already associated with the correct Column - we still need that ImportError on mysqldb CLIENT FLAGS to support mock DBAPIs

| | | | | | | | | | | in a separate collection. this collection also propagates during update() - ClassManager now handles bases, subclasses collections. - ClassManager looks at __bases__ instead of __mro__ for superclasses. It's assumed ClassManagers are in an unbroken chain upwards through __mro__. - trying to get a clear() that makes sense on cls.dispatch - implemented propagate for attribute events, plus permutation-based test - implemented propagate for mapper / instance events with rudimentary test - some pool events tests are failing for some reason

* - add instrumentation eventsMike Bayer2010-10-021-7/+26
| | | | | | | | | - simplify listen_for_events example with new system - add "propagate", "retval", "raw" flags to attribute events. this solves the "return value" issue as well as the "subclass" issue. - begin thinking about event removal. Each listen() method will have a corresponding remove(). Custom listen() methods will have to package all the info onto the event function that is needed to remove its state.

* - its probably worthwhile to make the primary listen() interface humane, i.e.:Mike Bayer2010-08-271-2/+56
| | | | | | | | | | | | | | | | def listen(target, args) so here we provide a "wrapper" approach that allows this, and it is basically pass-by-value. a pass-by-value event *may* support rewriting some of the args in the dictionary. the current listen will become "listen_raw" since it saves about 100% overhead versus the coercion to dict, and will be used internally, and will remain pass-by-reference. proxyconnection probably will rely upon the newer style of pass-by-value for "rewrite the args" types of calls.
* - reorganize events into cls->dispatch, which is an instance of _Dispatch.Mike Bayer2010-08-101-56/+79
| | | | | | cut down on extraneous stuff, cleanup The Event class never gets instantiated and its methods stay the same so that sphinx can get to it.
* this reorganizes things so the EventDescriptor and all is on a "Dispatch" ↵Mike Bayer2010-08-091-23/+31
| | | | | | | | | object. this leaves the original Event class alone so sphinx documents it. this is all a mess right now but the pool/engine tests are working fully at the moment so wanted to mark a working version.
