Finding the source file fails when the path on the target machine does not exist?

Thanks for your work on this project!

I'm not quite sure where the problem is, but basically, I have a small app (which just prints hello world) which I put on a remote machine. The full path to the executable is: /home/test/b (remote machine!). The source code of the app is: /home/goose/trash/learn-dbg/b.asm (local machine!).

I then run codelldb --port 13000 on the remote machine, create an ssh tunnel and successfully attached the adapter (nvim-dap).

When it breaks (either at a breakpoint or first entry), it shows me a decompiled version of that file.

It's not the source file, it's a temporary buffer with the decompiled code. However, note the second line:

; Source: /home/goose/trash/learn-dbg/b.asm:8

It thinks this path does not exist, but it in fact does exist! But only on the local machine with the editor.

I looked into the log and found this:

{
  body = {
    module = {
      addressRange = "7FFFF7FFD000",
      id = "7FFFF7FFD000",
      name = "[vdso]",
      path = "[vdso]",
      symbolStatus = "Symbols not found"
    },
    reason = "new"
  },
  event = "module",
  seq = 13,
  type = "event"
}

So I tried the following. I went into the remote machine and just created path /home/goose/trash/learn-dbg/b.asm. I didn't put any source code into it, I just created the path.

And guess what, it worked. I'm assuming codelldb tries to (for some reason?) check if a path exists, if it doesn't, it returns symbols not found. Otherwise it delegates the job of finding the source file to the client.

Is there some setting or something I can do to fix it?

• codelldb: v1.11.1
• nvim: v0.10.2
• nvim-dap: a6070b4e9e9a8ff1bc513c3748eff27080b0f44a

Note: codelldb works locally perfectly fine too. And if the path to the source file exists on the target machine (doesn't have to contain the actual source code), but not if it only exists locally

P. S.

This seems to cause it (./adapter/codelldb/src/debug_session.rs:1691):

let symbols = module.symbol_file_spec();
if symbols.is_valid() {
    msg.symbol_status = Some("Symbols loaded.".into());
    msg.symbol_file_path = Some(module.symbol_file_spec().path().display().to_string());
} else {
    msg.symbol_status = Some("Symbols not found".into())
}

But why does it assume that the files have to be local? Can it be configured somehow?

Oh. There's a whole guide on remote debugging. That should do it
