Actual behavior

The file test's test/hello.py is not found.

Expected behavior

The file test's test/hello.py is found.

Steps to reproduce:

1. Create a directory test's test.
2. Add a file hello.py with the line print('test') within that directory
3. Try to debug hello.py

Also try with the directory test'![](){}|=+-_*&^%$#@!<>,.?~`s test/hello.py

As a note, I can reproduce the issue on Linux (and it seems to work fine on Windows).

I'll investigate.

Ok, I've done some investigation and it seems to be an issue in VSCode itself (I'll report there and link the issue shortly)

Notes:

1. This works properly with internalConsole and with externalTerminal (so, it only fails with integratedTerminal).
2. The adapter appears to send the runInTerminal to the client properly. i.e.: the logs show:

D+00000.037: /handling #2 request "launch" from Client[1]/
             Client[1] <-- {
                 "seq": 4,
                 "type": "request",
                 "command": "runInTerminal",
                 "arguments": {
                     "kind": "integrated",
                     "title": "Python Debug Console",
                     "args": [
                         "/home/fabio/Desktop/miniconda3/envs/py37_tests/bin/python",
                         "/home/fabio/Desktop/debugpy_workspace/debugpy/src/debugpy/launcher",
                         "36577",
                         "--",
                         "/home/fabio/Desktop/debugpy_workspace/check/test's test/tests's.py"
                     ],
                     "env": {
                         "DEBUGPY_LOG_DIR": "/home/fabio/.vscode/extensions/ms-python.python-2021.5.842923320"
                     },
                     "cwd": "/home/fabio/Desktop/debugpy_workspace"
                 }
             }

3. When the args are actually received in the launcher, chars appear to be escaped (wrongly). i.e.: the log shows:

I+00000.024: sys.argv before parsing: ['/home/fabio/Desktop/debugpy_workspace/debugpy/src/debugpy/launcher', '36577', '--', "/home/fabio/Desktop/debugpy_workspace/check/test\\'s test/tests\\'s.py"]

4. The problem doesn't happen if there aren't spaces in the path, so, it seems that the issue is that VSCode is doing quoting once for the \' and then wrapping around with " due to the spaces on the path (which makes the launch fail).

So, this appears to be a bug in how VSCode is handling the runInTerminal (on Linux).

[fabioz]

I'm closing the issue here since the issue appears to be on VSCode, not really on debugpy.
