Issue 129: Memory consumption hyperoscillations
http://code.google.com/p/v8/issues/detail?id=129
Comment #15 by victor.grishchenko:
It looks like those FixedArrays are actually Dictionaries used by
JSObjects. I tried to print out
any features of those objects and it resulted in coredumps only:
791 void MarkCompactCollector::UpdateLiveObjectCount(HeapObject* obj) {
...
820 if (obj->IsJSObject() && jsocnt++%1000==0) {
821 JSObject* jso= JSObject::cast(obj);
822 //Logger::ApiObjectAccess("FUCK",jso);
823 printf("JSO\n");
824 //jso->JSObjectPrint();
825 //jso->PrintProperties();
826 //jso->class_name()->PrintOn(stdout);
827 jso->element_dictionary()->Print();
Judging by the number, those JSObjects must be some temporary objects which
leaked on
some reason as the number of long-living objects is orders of magnitude
lower.
Is there any way to profile it? How may I know class or origin of currently
allocated objects (or
why aren't they collected) ?
