Various debugging scenarios of embedded CPython

These 3 debugging scenarios below are based on 2 articles from PTVS docs:
https://docs.microsoft.com/en-us/visualstudio/python/debugging-mixed-mode https://docs.microsoft.com/en-us/visualstudio/python/debugging-cross-platform-remote
Important pre-requisites:
-
Install CPython with debugging symbols and binaries, like described in PTVS docs
-
Enable native code debugging in Visual Studio project settings
-
Python.NET 2.3.0+ and Visual Studio 2017, ptvsd 3.1.0+, Python 3.5+ are tested for these 3 scenarios
- Attach mixed-mode cross-language debugger (Python, Managed, Native) to pythonnet:
- switch to
DEBUG=1
. - select Managed (4.0+) + Native + Python debug engines manually.
- Attach Python debugger engine to Python code embedded with pythonnet:
- switch to
DEBUG=2
. - select Python debug engine manually.
- Attach Python remote debugger (ptvsd) to Python code embedded with pythonnet:
- switch to
DEBUG=3
. - select Python Remote Debugging option (ptvsd) in Connection Type.
- specify transport string in Connection target:
tcp://localhost@clr:5678
Program.cs
using System;
using Python.Runtime;
using System.Diagnostics;
using System.Threading;
namespace mixedmode
{
class Program
{
static void Main(string[] args)
{
dynamic res;
using (Py.GIL()) {
Console.WriteLine("embedded Python engine");
dynamic pymod = Py.Import("mixedmode");
Console.WriteLine("Imported testing module");
if ((int)pymod.DEBUG == 1)
{
AttachDebugger(); // enable this for mixed-mode debugging
}
res = pymod.pyfunc();
}
Console.WriteLine(res);
}
static void AttachDebugger()
{
Console.WriteLine("waiting for .NET debugger to attach");
while (!Debugger.IsAttached)
{
Thread.Sleep(100);
}
Console.WriteLine(".NET debugger is attached");
}
}
}
mixedmode.py
DEBUG=2 # 1 - mixed-mode cross-language debugger
# 2 - attach Python debugger
# 3 - ptvsd remote debugging
import clr
if DEBUG==2:
import sys
import time
while not sys.gettrace():
time.sleep(0.1)
elif DEBUG==3:
import ptvsd
ptvsd.enable_attach('clr')
ptvsd.wait_for_attach()
def pyfunc(args=None):
if args:
return args
else:
return "testing"
You can’t perform that action at this time.
