Hi everyone,

 

I’m investigating one issue regarding HTMLAudioElement objects leakage on a cuttherope.ie page on a custom QNX port.

What I’ve found so far is that JS object, holding WebCore::HTMLAudioElement is not deleted.

 

To be short,

markRoots is called from collectAllGarbage().

In markRoots() the code

 

    m_handleHeap.visitStrongHandles(heapRootVisitor);

    visitor.drain();

 

leads to marking JSHTMLAudioElement as being in use (testAndSetMarked()).

 

This way, I have  a weird situation:

I’ve navigated away from the page but the audio objects are marked as being in use.

 

Could you please direct me where I should dig further ? What should I check ?

Am I correct that there elements are stored as strong handles ?

 

Who decides which objects should be weak and which should be strong ?

 

Thank you for any help.

Andrey
