Parent indirection in launch configs cwd results in poor source maps

[ccarcaci]

Does this issue occur when all extensions are disabled?: Yes

When using the "double-dot parent folder indirection" in launch configuration (see image) the debugger stops working properly with typescript and source maps.

• VS Code Version:

1.63.0
7db1a2b88f7557e0a43fec75b6ba7e50b3e9f77e
x64

• OS Version:
  Ubuntu Linux Linux ccarcaci-N56JN 5.11.0-41-generic #45~20.04.1-Ubuntu SMP Wed Nov 10 10:20:10 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
  I have the same problem also on OSX on a different machine.

Steps to Reproduce.

Working case:

1. Checkout this repo https://github.com/ccarcaci/parent-cwd-issue
2. Select menu entry File > Open workspace from file...
3. Select the workspace.code-workspace from parent-cwd-issue/single-folder.
4. Run npm build pointing your console to parent-cwd-issue/single-folder.
5. Set a breakpoint in the index.ts file.
6. Open Run&Debug tab.
7. Launch "single folder" runnable configuration.
8. Debugger stops correctly on the breakpoint (see image).
   

Broken case:

1. Checkout this repo https://github.com/ccarcaci/parent-cwd-issue
2. Select menu entry File > Open workspace from file...
3. Select the workspace.code-workspace from parent-cwd-issue/multi-folder/workspace-launch.
4. Run npm build pointing your console to parent-cwd-issue/multi-folder/service-code.
5. Set a breakpoint in the index.ts file.
6. Open Run&Debug tab.
7. Launch "multi folder" runnable configuration.
8. Debugger is not stopping correctly at the breakpoint.
9. Open the file parent-cwd-issue/multi-folder/service-code/build/src/index.js.
10. Set a breakpoint.
11. Open Run&Debug tab.
12. Launch "multi folder" runnable configuration.
13. Debugger works correctly on compiled code (see image).
    

What's the difference?
The single-folder package has a launch configuration which uses the cwd default value (I've tried using a path without parent indirection and it works either).

The multi-folder package has a launch configuration which specifies a parent indirection in the cwd setting.

You'll want to configure your outFiles too by adding:

      "outFiles": [
        "${workspaceFolder}/../service-code/**/*.js",
        "!**/node_modules/**"
      ],

By default, VS Code will only scan the workspace folder for sourcemaps, and this adjusts that. We actually have logic to do this automatically, but it was only activated if a program was set, which is not the case for you.

You also most likely want to remove the disableOptimisticBPs.

This will be fixed in the next nightly build.

Also, a very topical log statement 😉
