Steps to reproduce the behavior:

• attach to gdb process
• click pause
• double click on stack frame

it opens a source window with the following contents:

Could not load source './../../content/app/content_main.cc': 'SourceRequest' not supported..

that path is relative to the executable, and the file exists and is readable.

Duplicate of #3662

[Spongman]

i don't think this is a dupe. if it is, it's not fixed. i'm running 0.24.0-insiders3 on 1.35.1, and i get the same error.

[Spongman]

ok, it seems like the source paths are resolved relative to the process' current working directory, which doesn't seem right. shouldn't they be resolved relative to either the debuggee's path itself, or some other directory?

[Spongman]

and what's worse, is that you can't set cwd for attach configurations, and if the child process changes its working directory to something else, it breaks source lookup in the debugger. and setting . in the sourceFileMap doesn't help.

[pieandcakes]

@Spongman Since I don't have a good repro, can you confirm that you are still seeing a NotImplementedException with 0.24.0-insiders3 or some other error?

For the source paths, we resolve them as your symbol file has them. if you want, you can specify sourceFileMap to redirect where the source files should be. You need a path as we don't support just the . character.

[Spongman]

so, what should i set my sourceFileMap to, in order to handle paths like this: ./../../content/app/content_main.cc ?

nothing i have tried works.

again. this is an attach configuration, and the debuggee changes the cwd.

i don't understand why i can't just map './../..' to some directory in my project, and have all paths with that prefix mapped to that location. the '.' in those paths is some build directory in the project, it's not the cwd of the debuggee, and it's not the location of debuggee's executable. and i can't change the build process.

[pieandcakes]

Looking at the implementation it might work on . if you include a slash (/ or \).

Here is the implementation we use: https://github.com/microsoft/MIEngine/blob/29c6569861b2042c43f04d8d78b2566db2e2ef1f/src/OpenDebugAD7/PathMapper.cs#L19

[ajihyf]

Same issue when debug in remote mode(using Remote SSH plugin)

[pieandcakes]

@ajihyf Can you let me know which version of the extension you are using?

[pieandcakes]

I misunderstood. The original issue of it crashing was fixed by us returning a failure but it looks like VS Code doesn't like that either.

[BertaBescos]

I am getting the same issue here. Did you get to solve this?

[pieandcakes]

@BertaBescos Is the failure blocking debugging? Do you have a repro that you can share?

[josepharhar]

I'm using this feature to debug chromium on linux and It looks like I'm running into the same issue:

Could not load source './../../third_party/blink/renderer/core/dom/element.cc': 'SourceRequest' not supported..

Here is my launch.json:

{
  // Use IntelliSense to learn about possible attributes.
  // Hover to view descriptions of existing attributes.

      "processId": "${command:pickProcess}",
      "MIMode": "gdb",
      "miDebuggerPath": "/usr/bin/gdb"
    }
  ]
}

[pieandcakes]

@josepharhar we don't support sourceRequest currently so we return a failure to VS Code which I had assumed would allow debugging to continue. Can you let me know if this ends up terminating the debug session? I can try and change the code there but i haven't been able to get a repro where i can set it up and debug the scenario.

[josepharhar]

It does not terminate debugging, I can unpause execution and hit the same breakpoint i set over and over again. Setting up chromium to repro would take a long time if you haven't done it before unfortunately, and I'm not sure what's wrong to provide a good repro. All I know is that with regular gdb it works fine.

Not sure if this helps, but I also get this message in the debug console when I first attach:

Superuser access is required to attach to a process. Attaching as superuser can potentially harm your computer. Do you want to continue? [y/N]

Just wondering, what is sourceRequest?

[pieandcakes]

@josepharhar It is something that VS Code is requesting from us through the debugAdapterProtocol. The error, if it isn't stopping debugging, should be ignorable.

[pemgithub]

I get the error when trying to step into Google ANGLE source code (on Ubuntu in Visual Studio Code). It prevents debugging. I am not able to step into code. When I step lines of code, it just prints the error:

Could not load source './../../samples/sample_util/SampleApplication.cpp': 'SourceRequest' not supported..

@pemgithub Does that source code exist on your machine in the location specified based on your cwd? If not, you can set up a sourceFileMap to point to the correct location.

[pemgithub]

@pieandcakes thank you for the help; I was able to get it working by changing this:
"cwd": "${workspaceFolder}/out/Debug",

[pemgithub]

@pieandcakes using cwd fixed it for code that's relative to my cwd. However, for a different project, I also wanted to step into external code (from libGLESv2.so which I built from source)... For external code, I got a similar error - "./../../src/libGLESv2/libGLESv2_autogen.cpp". So I added the following to my launch.json (which seems to have worked):
"sourceFileMap": { "./../../src/": "~/pemCode/angle/src/" }
