Debug adapter process has terminated unexpectedly

[ghost]

Environment data

VS Code version: 1.19.2
Python Extension version: 0.9.1
Python Version: 3.6.4
OS and version: Arch Linux(with testing repo)

Actual behavior

Debug adapter process has terminated unexpectedly.

Expected behavior

The debugging process should continue throughout the script execution.

Steps to reproduce:

• Run loop with HTTP requests in Process(parallel requests) and output to the console for each HTTP request (print ("some information about the response")).
• Use configuration for running:

{
            "name": "run.py",
            "type": "python",
            "request": "launch",
            "stopOnEntry": true,
            "pythonPath": "${config:python.pythonPath}",
            "program": "${workspaceFolder}/run.py",
            "cwd": "${workspaceFolder}",
            "env": {},
            "envFile": "${workspaceFolder}/.env",
            "debugOptions": [
                "RedirectOutput"
            ]
}

Logs

Please could you provide some sample code with instructions to replicate this issue?

VSCode: 1.20.1 (1.20.1) - MacOS
Python plugin: 2018.1 (01 Feb 2018)
Python version: 3.6.4 on MacOS, 3.5.5 on Armbian (Banana PI M1+)
ptvsd: 3.0.0 on both MacOS and Server (even tried with the newest one, no change)

Attach configuration:

  {
      "name": "LowBattery: Remote",
      "type": "python",
      "request": "attach",
      "localRoot": "${workspaceFolder}",
      "remoteRoot": "/home/djmanas/python",
      "port": 3333,
      "secret": "my_secret",
      "host": "192.168.1.101"
    },

Code server.py:

#!/usr/bin/env python3
""" Simple script that will notify user when modules are under certain battery percent """
import ptvsd

ptvsd.enable_attach("my_secret", address=('192.168.1.101', 3333))
ptvsd.wait_for_attach()

print('test‘)

In VSCode, after upload, comment out debug lines.

On server through SSH python3 server.py

It waits for attach netstat -lnp

Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name
tcp        0      0 192.168.1.101:3333      0.0.0.0:*               LISTEN      30357/python3

Launch the LowBattery: Remote debug configuration and you will get the error.

Does the same thing when I redirect the port through ssh -L 3333:127.0.0.1:3333 and change every IP to localhost.

Ok, opening new issue. To be honest I had browsed a lot issues like mine. In some I have read, that ptsvd can be higher than 3.0.0. And I am totally lost in your bug tracker... A lot of hyperlinks to other issues...
