Debugging across http requests throws exception

[willm]

Hi,

I hope this is the right place to post this, but I think I've found an issue with node debug.

Given this code in test.js:

var http = require('https');
http.get('https://nodejs.org', function (res) {
    debugger;
}).on('error', function (e) {
    throw e;
});

node debug test.js                                                                                                               20 ↵
< Debugger listening on port 5858
debug> . ok
break in test/t.js:1
> 1 var http = require('https');
  2     http.get('https://nodejs.org', function (res) {
  3         debugger;
debug> c
break in test/t.js:3
  1 var http = require('https');
  2     http.get('https://nodejs.org', function (res) {
> 3         debugger;
  4     }).on('error', function (e) {
debug> repl
Press Ctrl + C to leave debug repl
> res
< iojs: ../src/util-inl.h:196: TypeName* node::Unwrap(v8::Local<v8::Object>) [with TypeName = node::TLSWrap]: Assertion `(object->InternalFieldCount()) > (0)' failed.
program terminated

I think this should be allowing me to inspect the res object. Not sure if this is a node or V8 issue though. I'm running node 4.0.0 on Ubuntu 14.04.3 LTS

node --version
v4.0.0

Is it possible that you have an older iojs binary on your PATH? The iojs: in the assert message is suspicious.

[willm]

It's possible (I use n to manage multiple node/iojs versions). So I tried to mitigate this using the node:4.0.0 docker image and still get an error, but no mention of iojs.

node debug test.js
< Debugger listening on port 5858
debug> . ok
break in /test.js:1
> 1 var http = require('https');
  2 http.get('https://nodejs.org', function (res) {

debug> c
break in /test.js:3
  1 var http = require('https');
  2 http.get('https://nodejs.org', function (res) {
> 3     debugger;
  4 }).on('error', function (e) {
  5     throw e;
debug> repl
Press Ctrl + C to leave debug repl

It's possible v4.0.0 had a missed error message somewhere, @willm can I get you to try v4.2.2?

[willm]

Same issue with 4.2.2, it seems to go way back (I also tried 0.10.40)

node debug test.js 
< Debugger listening on port 5858
debug> . ok
break in /test.js:1
> 1 var http = require('https');
  2 http.get('https://nodejs.org', function (res) {
  3     debugger;
debug> c
break in /test.js:3
  1 var http = require('https');
  2 http.get('https://nodejs.org', function (res) {
> 3     debugger;
  4 }).on('error', function (e) {
  5     throw e;
debug> repl
Press Ctrl + C to leave debug repl

Is this nodejs/node-v0.x-archive#9028 ? because that's also reproducible on v5.1.0
> process.binding('crypto').Connection.prototype
--> crash

[willm]

It looks like it could well be the case. I've tested all the versions and can confirm that the regression happened in 0.11.14 (0.11.13 works fine)
