visual studio code c++툴 수정 기여하기

알아낸 내용에 대해서 생략하고 수정한 것만 리퀘스트한 결과 리뷰어로부터 내가 어떤 것들을 시도했는지에 대한 요청을 받았다.

My Environment:

  • Visual Studio Community 2019 for MIEngine build.
  • Visual Studio Code 1.41.1
  • Visual Studio Code C/C++ extension 0.26.3
  • Powershell core 6.2.3
  • MinGW-w64 8.1.0 posix-seh

At first I didn’t know why debugging with powershell not works but cmd or with external console work. So I checked L

@Epikem Thank you for your submission. Can you tell me what you tested so know what else needs to be tested?

I tested this fix by replacing content in vscode cpp-tools’ debugAdapters folder (C:\Users\Administrator\.vscode\extensions\ms-vscode.cpptools-0.26.3\debugAdapters) and launching vscode debug after that.

I checked the error(timeout) happened here does not appear with increased delay. When I launch debug, it opens new powershell terminal which usually fails by connection failure. But the connection failure does not occur when I don’t close newly launched terminal and reuse it by stopping running command (WindowsDebugLauncher.exe) using ctrl+c, or if I remove all of the content in my powershell profile. And I checked same error happens even after increase delay(20s) when I add additional 20 second delay in powershell profile.

This is vscode debug console log when timeout happened:
