vscode-python: remote debug hangs when remote is python3

From @bradanlane on March 8, 2017 23:28

Environment data

VS Code version: 1.10.2 Python Extension version: tested 0.5.9 and 0.6.0 Python Version: local: windows 3.5.3 remote: raspbian 3.4.2 OS and version: local windows 10, remote raspbian jessie (debian 8)

Actual behavior

start remote program (python3 tutorial01.py) and then start local debugger and then it just waits

Expected behavior

if I start the remote program with python 2.7.9 (python tutorial01.py) remote debugging works and my local display stops at the first breakpoint

Steps to reproduce:

• (installed ptvsd for both python and python3)
• start program on remote using python3 tutorial01.py
• remote program waits
• start debugger on local and the control bar appears and then it just waits
• stop remote program and local debugger
• start program on the remote using python tutorial01.py
• start debugger on local and control bar appears with all options enabled
• first breakpoint is highlighted

Settings

Your launch.json (if dealing with debugger issues):

{
            "name": "Attach (Remote Debug)",
            "type": "python",
            "request": "attach",
            "localRoot": "${workspaceRoot}",
            "remoteRoot": "/home/pi",
            "port": 3000,
            "secret": "nosecret",
            "host": "192.168.6.47"
}

Your settings.json:
(I tried with and without the following line)

"python.pythonPath": "c:/tools/python3/python3.exe"

Logs

Output from Python output panel

no output generated  when trying to use python3 on remote

Output from Console window (Help->Developer Tools menu)

no output generated when trying to use python3 on remote

##Test program

import ptvsd
#ptvsd.enable_attach("nosecret")
ptvsd.enable_attach("nosecret", address=('0.0.0.0', 3000))
ptvsd.wait_for_attach()
#ptvsd.break_into_debugger()

print ('starting ...')
person = input('Enter your name: ')
print('Hello', person)
print(' ... finished')
