Hi,
I have a few questions about inspector/JS debugging feature. I am trying
to get a JS frame after
pausing script execution due to breakpoint reach. If I understand good
the „pausedScript” event that is send to my InspectorClient class via
the sendMessageToFrontend function should has JS frame that I looking for.
{"type":"event","event":"pausedScript","data":{"callFrames":null}}
But the callFrames field is null. The “callFrames” field is filed by an
InspectorDebuggerAgent::currentCallFrames() function. Could you tell me
what is an InjectedScriptHost class what is the purpose of this class
and how I should use this object to get a callFrame? Maybe I have
forgotten to dispatch some commands?
What commands should be dispatched via an InspectorBackendDispatcher
object to get a callFrame after JS execution pause?
For test purpose I have written a code:
InspectorDebuggerAgent::currentCallFrames()
{
JavaScriptCallFrame* frame =
ScriptDebugServer::shared().currentCallFrame();
if (!frame)
{
fprintf(stderr, "source: %d\n", frame->sourceID());
fprintf(stderr, "line: %d\n", frame->line());
fprintf(stderr, "function: %s\n",
frame->functionName().ascii().data());
JSC::JSGlobalObject *gobject = frame->dynamicGlobalObject();
JSC::ExecState* exec = gobject->JSGlobalObject::globalExec();
if (exec)
fprintf(stderr, "function parameters: %d \n",
exec->argumentCount());
}
But exec->argumentCount returns invalid parameters count.
Best regards,
Tomasz Morawski
