I have a node.js server that periodically spikes to 100% CPU usage in
production. I would like to be able to send it a signal which causes a
stack trace, to see where the problem is. So I want to build a custom
version of node that listens for a signal and calls v8 to print the current
stack. It looks like the function I need is
v8::internal::Isolate::Current()->PrintStack(stdout);
My c++ skills are pretty rusty, however if I understand correctly, because
this is in the internal namespace I'm not able to access it:
../src/node.cc:3767:21: error: incomplete type 'v8::internal::Isolate'
named in nested name specifier
v8::internal::Isolate::Current()->PrintStack(stdout);
~~~~~~~~~~~~~~^~~~~~~~~
../deps/v8/include/v8.h:130:7: note: forward declaration of
'v8::internal::Isolate'
class Isolate;
^
1 error generated.
Is there some other way to cause v8 to print a stack trace?
Thanks,
Dirk
