Appreciate your help so far.
Sample user JS code[0] looks like this now:
{code}
function OnUpdate(doc, meta) {
log("doc meta id: ", meta.key);
if (meta.type === "json" && doc.ssn) {
..
..
}
}
Debug = debug.Debug;
log(Debug.showBreakPoints(OnUpdate));
Function OnDelete() {}
// more functions
{code}
===
* Fired command:
{"command": "setbreakpoint", "type": "request", "arguments": {"type":
"function", "target": "OnUpdate"}, "seq": 862}
* show.BreakPoints(“OnUpdate”) dumps the function definition:
"(doc, meta) {\n log(\"doc meta id: \", meta.key);\n\n if (meta.type ===
\"json\" ) {\n log(\"doc.ssn field: \", doc.ssn);\n\n updated_doc =
CalculateCreditScore(doc)\n credit_bucket[meta.key] = updated_doc;\n\n
var value = credit_bucket[meta.key];\n\n //delete
credit_bucket[meta.key];\n\n var d = new Date();\n var n =
ISODateString(d);\n log(\"ISO 8601: \", n);\n\n
registerCallback(\"CallbackFunc1\", meta.key, n);\n order_queue[meta.key];\n
}\n}"
I guess it confirms that breakpoint has been set using C++ apis

One new problem that I see now, when I’ve :
{code}
Debug = debug.Debug;
log(Debug.showBreakPoints(OnUpdate));
{code}
as part of user JS code, I see a crash from V8 when “Call” to “OnUpdate”[1] is
made . All I get from V8 about that crash was:
fatal error: unexpected signal during runtime execution
[signal 0xb code=0x1 addr=0x0 pc=0x4dc05f1]
Could I get a bit more verbose error message, which I could make sense of? :)
BTW Ben, do you hang around on any IRC room? Understand you’re much busy, but I
suppose I can fix things much sooner on my end using your help via IRC
communication than email :) Else I could continue using this thread.
