Cannot attach to a process for debugging

[chance-sematic]

Type: Bug

Behaviour

Seeing the logs in output when attaching python debugger to a process:

Expected vs. Actual

Debugger can attach to a process successfully.

Steps to reproduce:

Using the following launch config to attach debugger to a proces:
{
"name": "Python: Attach using Process Id",
"type": "python",
"request": "attach",
"processId": "${command:pickProcess}",
"justMyCode": true
},

Diagnostic data

• Python version (& distribution if applicable, e.g. Anaconda): 3.8.15
• Type of virtual environment used (e.g. conda, venv, virtualenv, etc.): Pyenv
• Value of the python.languageServer setting: Default

Output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python)

same problem.

[microboym]

The extension use lldb as the debugger as default. Considering that it might a problem with lldb, I've attempted to install gdb on my machine, but I got this

brew installl gdb
...
gdb: The x86_64 architecture is required for this software.
Error: gdb: An unsatisfied requirement failed this build.

Sincerely hoping for help.

[chance-sematic]

To quickly unblock, one can try this ( add this to the main file of your Python program, remove after debugging and before committing)

import ptvsd
ptvsd.enable_attach(address=('localhost', 5724), redirect_output=True)
print('Now is a good time to attach your debugger: Run: Python: Attach')
ptvsd.wait_for_attach()

This could help the maintainers confirm that it is indeed the same issue.

(I am just helping out and clarify, I am not the one to fix it)

error: expression failed to parse:
error: <user expression 1>:1:6: use of undeclared identifier 'DoAttach'

This could help the maintainers confirm that it is indeed the same issue.

My output seems to show the same cause.

I am also seeing this issue, has there been a resolution?

Same issue for me on Mac M1 with Visual Studio Code (1.89.1 (Universal))
sys.path.insert(0, script_dir);import attach_pid_injected;del sys.path[0];attach_pid_injected.attach(setup); error: error: <user expression 1>:1:6: use of undeclared identifier 'DoAttach'

I have encountered this problem as well. How can I solve it?

We recently fixed a bunch of attach issues in the latest version of debugpy, please try that (it should be available in the latest version of the python Debugger extension). If you continue to have this issue please file on https://github.com/microsoft/debugpy.
