remotePath of '/' when debugging remote linux container translates breakpoint paths to windows local paths

[FrankSzendzielarz]

On Windows 10 , building a Linux docker container, add the files to a subfolder such as x/y/z

run the container with security-options="seccomp=unconfined' (and an entrypoint running dlv as follows:

dlv test --headless --listen=:2345 --log=true --api-version=1 )

In VSCODE, make sure the files you are debugging are also in a local c:<workspace>\x\y\z (otherwise breakpoint matching does not work ever anyway).

In launch.json set the remotePath to "/" (see below)

With verbose logging, note that the breakpoint cannot be set or verified, because it translates the path to C:<workspace>\x\y\z (windows file separator)

Repeat the process adding the source files instead to a subfolder eg /src/x/y/z

Set remote path to /src/

Breakpoints now work because VSCode translates the breakpoint path to Linux file separated absolute path.

        "type": "go",
        "request": "launch",
        "mode": "remote",
        "program": "${workspaceFolder}",
        "env": {},
        "args": [],

        "remotePath": "/",

        "port": 2345, // Port 

        "host": "172.17.0.2" ,
        "showLog": true,
        "trace": "verbose"

    }

You do this in the container or on Windows?

[FrankSzendzielarz]

Always must be both for breakpoints to work. So src would be the root of the path on docker, and root relative to gopath locally
