Describe the bug

I'd like to make the absolute path of go files relative in order to be able to set breakpoints in vscode. If I add

    {
        "name": "Attach to Process",
        "type": "go",
        "request": "attach",
        "mode": "local",
        "processId": "cs",
        "cwd": "",
        "substitutePath": [
            {
                "from": "/home/sgyger/.../",
                "to": "",
            }
        ]
    }

to launch.json, then launch the debugger, I get image

This issue, which includes an empty "to" field, makes me think that it's a bug.

I hope I'm approaching the problem right. The reason why I'm trying to achieve this in the first place is because I can't set break points with absolute paths when launching dlv from the terminal, but I can do it with realtive paths.

When I don't subsitute paths at all, I get the following when setting breakpoints:

This should be fixed in Delve.

hyangah avatar Jan 14 '22 20:01 hyangah

@hyangah What do you mean?

Nearoo avatar Jan 15 '22 11:01 Nearoo

@Nearoo Sorry for my unclear comment. This is an issue in dlv dap and this guard should be removed. @suzmue Is it ok to remove this check ?

hyangah avatar Jan 18 '22 14:01 hyangah

@hyangah We definitely will need to check the locspec.SubstitutePath implementation, since from the command line it was not possible to set to as the empty string. I believe there may be modifications required for how the rules are applied to make sure it will work before removing the guard.

suzmue avatar Jan 18 '22 19:01 suzmue

@Nearoo I have a couple of questions about your setup to understand your use case. Could you provide more information about how the process you are debugging was built (ideally the build command that was used)?

Could you also go to the debug console after attaching to the process and request dlv sources (or get the output of sources from the delve terminal client)? If you are not comfortable sharing that full output, showing what the path of the file you were attempting to set a breakpoint in would be helpful.

Thank you so much!

Sure, although I must admit that I'm fairly new to this repo and might not fully understand the build & run commands. I'm working on this repo, which implements a networking protocol. In the setup I'm trying to run, there are multiple build targets built using bazel (defined here), before they're deployed on multiple containers using supervisord, with commands that are generated based on a config file and saved in gen/supervisord.conf. Launch happens in the .sh file here. Here's an process configuration defined inside the gen/supervisord.conf file of a process which I'm trying to attach to:

[program:cs1-ff00_0_112-1]
autostart = false
autorestart = false
environment = TZ=UTC

bin/cs is a build target, configured with this bazel file, if that's relevant. Hope this is about what you're looking for, and that this is understandable.

dlv sources returns the following:

  • many external/... packages, e.g. external/org_uber_go_zap/zapcore/write_syncer.go
  • all local packages with relative paths, e.g. go/cs/beacon/beacon.go, including the file I'm trying to set a breakpoint in.

Thanks for the effort!

Wondering if rules like the following can be set up

  "substitutePath": [
     {
         "from": "${workspaceRoot}/go",
         "to": "go"
     },
     {
         "from": "<local directory for external/org_uber_go_zip>",
         "to": "external/org_uber_go_zap"
     },
   ]

This was fixed with https://github.com/go-delve/delve/pull/3088 which landed in delve 1.9.1+.
