Summary: The FormScriptingEnvironment object created in the
FmXUndoEnvironment ctor is never released
Severity: normal
Issue Type: DEFECT
Classification: Code
OS: All
Reporter: [email protected]
Hardware: All
Status: CONFIRMED
Version: AOO 3.4.0
Component: code
Product: performance
In FmXUndoEnvironment ctor, it calls
m_pScriptingEnv( ::svxform::createDefaultFormScriptingEnvironment( _rModel )
)
creates a FormScriptingEnvironment object.
And in svxform::FormScriptingEnvironment ctor api, it creates
ListenerImplementation object,
FormScriptingEnvironment::FormScriptingEnvironment( FmFormModel& _rModel )
:m_refCount( 0 )
,m_pScriptListener( NULL )
,m_rFormModel( _rModel )
,m_bDisposed( false )
{
m_pScriptListener = ListenerImplementation( new FormScriptListener(
this ) );
// note that this is a cyclic reference between the FormScriptListener
and the FormScriptingEnvironment
// This cycle is broken up when our instance is disposed.
}
So there is cyclic reference between FormScriptingEnvironment and
ListenerImplementation object. It needs call to it's
FormScriptingEnvironment::dispose() api to break the cyclic reference before it
can be released.
But before FmXUndoEnvironment::~FmXUndoEnvironment() is called,
FmXUndoEnvironment::dispose() is not never called, so the
svxform::FormScriptingEnvironment object get leaked.
