Python 3.10 fails to hit breakpoints when "Native Code Debugging" is enabled. #6900

Open ttSpace opened 2 years ago

ttSpace commented 2 years ago

Describe the bug

image

Install Python 3.10 from https://www.python.org/

Steps to Reproduce

  1. Create a Python Application project, add simple Python code. 
    
from math import cos, radians

Create a string with spaces proportional to a cosine of x in degrees

def make_dot_string(x): rad = radians(x) # cos works with radians numspaces = int(20 cos(radians(x)) + 20) # scale to 0-40 spaces st = ' ' numspaces + 'o' # place 'o' after the spaces return st

def main(): for i in range(0, 1800, 12): s = make_dot_string(i) print(s) main()

2. Enable "Native Code Debugging" in project settings / debug page.
3. Set breakpoint and start debugging.

**Expected behavior**

Breakpoint should be hit.

**Additional context and screenshots**

Breakpoint can not be hit.

Can you check if Python symbols were loaded correctly for python310.dll? You should be able to see it in the Modules window (under Debug -> Windows).

ttSpace commented 2 years ago

The Module window is shown below.

We need to figure out whether we're planning to support 3.10 for this feature.

AdamYoblick commented 1 year ago

@judej @cwebster-99 We need some PM guidance on this. Are we planning on supporting mixed mode debugging for 3.10?

The fact that it shows messages like "Loaded Lib/...py" in the console indicates that the mixed-mode debugging is in effect, meaning that it already loaded all the symbols that it needed.
