Describe the bug

This warning pops up, even though I am able to connect and debug:

'remote' mode with 'dlv-dap' debugAdapter must connect to an external `dlv --headless` server @ v1.7.3 or later. Older versions will fail with "error layer=rpc rpc:invalid character 'C' looking for beginning of value" logged to the terminal.

This warning appeared under dlv 1.7.1. I upgraded to dlv 1.8.0 and it remained.
I expect a warning only if there is an issue that needs to be addressed.

Steps to reproduce the behavior:

Start dlv debug in headless mode: dlv debug --headless --listen=:12345

Create a launch config:

{
  "name": "Connect to external session",
  "type": "go",
  "debugAdapter": "dlv-dap", // `legacy` by default
  "request": "attach",
  "mode": "remote",
  "port": 12345,
  "host": "127.0.0.1" // can skip for localhost
}

Add a breakpoint to the main function.
Run the launch config
Observe the warning popup.

@tekumara Can you start the remote debug server with logging enabled (--log --log-output=rpc,dap,debugger) and share its log (of the remote debug server)?

No problem, here are the logs:

Thanks @tekumara
The log shows debugging works (breakpoint worked, threads/stackTrace/variables requests succeeded, ... ), but the extension still showed this incorrect popup spuriously. Does it match your observation?

cc @polinasok @suzmue

tekumara · 2022-01-19T02:56:17Z

Yep - debugging works but the popup is spurious.

polinasok · 2022-01-19T17:55:01Z

This pop-up is not an error. It is informational and was designed to let the users know that they were switching to using dlv-dap for remote, which was previously always using legacy. We don't have a way to tell what version the remote server is, so this was triggered in all cases just in case the user stumbled into the dlv-dap remote mode by accident. The idea was that once the user confirms their set-up, they could just disable with "Don't Show Again" and never see this again.

polinasok · 2022-01-19T17:59:50Z

Sorry, posted before I was done typing. We realized that this could be confusing and interpreted as an error, so we tweaked the wording - see #1945 (comment), but this unfortunately didn't make it into the current release. Our plan was to remove the start-up warning once the user community was aware of the dlv-dap remote mode.

hyangah · 2022-01-19T18:01:47Z

@polinasok I suspect there is a bug that caused this popup show (maybe a race?) even when the remote debugging using dlv-dap was successful.

Edit: Oh, I see. I think this popup is distracting and should use Information (not Warning) if we want to keep this.

polinasok · 2022-01-19T18:05:41Z

@hyangah No, there is no race, this always shows up on start-up and is working as intended. With nighlty it would still show up, but will be less confusingly worded. Please see #1945. We were in the middle of deciding whether to take it out completely in case users get confused and think it is an error (like they did here), but then the extension got released as-is, and this topic got dropped.

polinasok · 2022-01-19T18:08:24Z

Edit: Oh, I see. I think this popup is distracting and should use Information (not Warning) if we want to keep this.

We had that discussion too: https://go-review.googlesource.com/c/vscode-go/+/371974/1/src/goDebugConfiguration.ts#178
I think at this point, we might as well take this out completely since there is now another pop-up when the session fails.
