Debugger doesn't exit after program run

[SetTrend]

When debugging the following simple project (only a gulpfile.js) in VS Code, the debugger doesn't exit after the last line of code has been executed:

Gulp4ParallelTest.zip

The VS Code team suggests that this is a problem in the Node runtime.

I feel it's quite confusing not to safely know whether all threads/processes in a program have finished or not when debugging.

What node version are you using?

What command are you running to start it?

Can you please post the example to something like gist or another pasting service? (Also please try to make a test-case that does not require npm modules to reproduce.)

I have lost my VM over the weekend so I can't tell. But I'm sure it was Node 4.

For details on how I started the Node debugger, please refer to the issue I cross-referenced above:

microsoft/vscode#3339

Unfortunately this is not quite enough information to go off of. I know it may be difficult to do so, but we'll need a reproduceable test case that demonstrates the issue before we can adequately diagnose the problem.

Of course, I apprehend. Yesterday I was able to setup a new VM with latest versions of all my development software. I'll create a test case over the weekend and keep you updated.

I'm running the latest safe Node version: 4.4.0.

Here's a log of the debugging session I started:

PS D:\Documents\Visual Studio-Projekte\VS Code\Gulp4ParallelTest> node debug .\gulpfile.js
< Debugger listening on port 5858
debug> . ok
break in D:\Documents\Visual Studio-Projekte\VS Code\Gulp4ParallelTest\gulpfile.js:2
  1 ///<reference path="headers/chalk/chalk.d.ts"/>
> 2 "use strict";
  3
  4 let gulp = require("gulp");
debug> cont
debug>

As you can see, the debugger doesn't quit after the last thread has ended running.

Here's the same code, debugged using a GUI (i.e. Visual Studio Code):

I'm going to investigate this week

Great. Thanks!

I'm going to close this as a duplicate of #1788

I'll be continuing my investigation in that thread
