|Subject: [PATCH] Closed two major memory leaks for scripted objects
|
|Two major memory leaks for the scripted objects were fixed
|- One leak had to do with remoting acrossing app domains. When a script and
| its controlling agent communicate across an application boundary, it calls
| functions on a stub proxy object that then invokes the remote method on
| the object in the other app domain. These stub objects (two for each script)
| were setup to have infinate lifetimes and were never being garbage collected.
|- The second leak was the result of adding a scene object part instance method
| to a scene event and never removing it. This cause the event's delegate list
| to maintain a link to that object which is then never freed as the scene event
| object is never destroyed.
Patch applied, please direct feedback to me. Possible issue: Longtime idle
scripts like vendors may fail.
* Added log4net dependency to physxplugin in prebuild.xml.
* Added missing m_log fields to classes.
* Replaced Console.WriteLine with appropriate m_log.Xxxx
* Tested that nant test target runs succesfully.
* Tested that local opensim sandbox starts up without errors.
Prevent EventAbortException inner exceptions of
TargetInvocationException being re-thrown from
OpenSim.Region.ScriptEngine.Shared.ScriptBase.
Executor.ExecuteEvent
Addresses llDie issues. The attached patch catches run time
exceptions that occur during method invocation (of type
TargetInvocationException) and exposes the internal exception.
This makes it possible to pass out the SelfDeleteException.
Also added handlers in a couple places to make sure that
exception was being passed out far enough to be handled
correctly. Tested on DNE.
