I've got code to create a JS object that wraps a C++ object.
I'm using a weak pointer from the C++ object to the JS object to detect when
the JS object is collected so that I can delete the C++ object.
I can't yet demonstrate that the C++ object is deleted. I wrote a simple loop
in JS
function f()
{
for (i = 0; i < 1000; ++i)
{
new jfx.ByteBuffer();
}
}
and run v8 with the flags
--log_handles --gc_interval=10 --trace_gc --gc_global
I get debugging messages
constructed byte buffer 0x8a1e0e8, isWeak = 1
0x8a1e0e8: isWeak=1, isNearDeath=0
Mark-sweep 0.4 -> 0.4 MB, 20 ms.
constructed byte buffer 0x8a440f8, isWeak = 1
0x8a1e0e8: isWeak=1, isNearDeath=0
The weak pointers are never marked as NearDeath.
>From v8.log I get
GlobalHandle::MakeWeak,0x8a538b4
GlobalHandle::MakeWeak,0x8a538b4
markcompact,begin,2,797574,1224457984667
markcompact,end,2,809572,1224457984679
scavenge,begin,2,809572,1224457984679
scavenge,end,2,810572,1224457984679
GlobalHandle::MakeWeak,0x8a538b4
so you'd think that if the JS objects were no longer referenced then I would
see them deleted.
So what do I have to do to generate garbage in scripts if the above for-loop
doesn't do it.
