Descrizione

bug needs repro user responded

Issue Type: Bug

Behavior

When attached to a local process running Azure Functions, the python debugger gets stuck indefinitely at a set breakpoint, and there is no response to clicking step forward button etc. The variables window is also empty and loads indefinitely.

Setup

VS Code:

Version: 1.93.1 (user setup)
Commit: 38c31bc77e0dd6ae88a4e9cc93428cc27a56ba40
Date: 2024-09-11T17:20:05.685Z

Chromium: 124.0.6367.243
Node.js: 20.15.1
V8: 12.4.254.20-electron.0
OS: Windows_NT x64 10.0.22631

**

launch.json

{
"version": "0.2.0",
"configurations": [
{
"name": "Attach to Python Functions",
"type": "debugpy",
"request": "attach",
"port": 9091,
"preLaunchTask": "func: host start"
}
]
}
tasks.json
...
"tasks": [
{
"type": "func",
"label": "func: host start",
"command": "host start",
"problemMatcher": "$func-python-watch",
"isBackground": true,
"dependsOrder": "sequence",
"dependsOn": ["pip install (functions)"],
...
}, ...
...

Steps to reproduce:

  1. Click "Run and Debug" to run launch.json "Attach to Python Functions", which will start local Azure Functions serverless app via command 'func host start' and attach to that process.
  2. Set breakpoint anywhere in any Function
  3. Trigger the breakpoint
  4. Debugger hangs indefinitely and cannot see local or global variables. Cannot exit process through CTRL+C. This happens inconsistently, may sometimes step through normally in the same breakpoint without changing the code.
  5. Debug console is also unresponsive (try typing any command while stuck at breakpoint like print("test") and there is no output)
  6. Need to restart Azure Functions App by clicking terminal trash can button or "detach" button in debug menu to get unstuck.

Things tried

  1. Switch Python extension version to pre-release
  2. Restart VS code
  3. Re-install Azure Functions extension
  4. Re-install Azure Core Tools
