Category: Other Group: Next Major Release Status: Open Priority: 5 Submitted By: Wyrm Tools (wyrmtools) Assigned to: Wyrm Tools (wyrmtools) Summary: Dynamically remove model elements as plugins are stopped Initial Comment: At some point, Wyrm Tools is going to support dynamically stopping plugins while the application is running rather than only stopping them when it is shutdown. BUG 1519066 documented a problem in which the d20 core plugin was stopped, but the model still contained references to d20 model elements, causing ClassNotFoundExceptions to be thrown. The fix implemented was simply to close the model when the d20 core plugin was stopped. We need to support a more robust method that can handle arbitrary plugins being stopped at any time. I can think of two possible designs at this time: 1) Add a new method to IModel that closes any openable elements which contains elements defined by the plugin being stopped. Maybe something like: public void close( ClassLoader cl ); It would have to iterate through all the registered elements in the model looking for ones whose ClassLoader matches the specified one (presumed to be the stopping plugin's ClassLoader). Thus, every plugin which contributes classes to the model must call this method in their stop() method. 2) Have the model implementation listen for plugins being stopped and do the same thing as in (1). This has the added benefit of not requiring plugin authors to worry about cleaning up after themselves. At this point, I'm not sure if we can intercept a notification that says a plugin is about to be stopped rather than receiving the notification after the fact. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=724981&aid=1519075&group_id=132696 |
