debug: cannot import absolute path

[alexandre-kovalenko]

Looks like

https://github.com/Microsoft/vscode-go/issues/905

resurfaced in 0.27.0.

Rolling back to 0.26.0 resolves the issue.

I am not sure I can add much to the original report, but, if there's any information that need to be provided, kindly, let me know.

[alexandre-kovalenko]

Nightly build v2021.8.919 exhibits the same issue.

Rolling back to 0.26.0 I can successfully step through the code above.

This is caused by the difference in the way to build the binary for debug in the new dlv-dap adapter.

@alexandre-kovalenko Workarounds:

1. Consider using the module mode (add go.mod file in the workspace root). See https://golang.org/doc/tutorial/getting-started or,
2. less-recommended way: switch back to the legacy, old debug adapter https://github.com/golang/vscode-go/blob/master/docs/debugging.md#switching-to-legacy-debug-adapter

@suzmue @polinasok To handle this ad-hoc mode build (not module mode nor GOPATH mode), we may need changes in dlv dap:

• option 1: like the legacy debug adapter, build with go build . instead of go build <program>.
• option 2: allow empty string or a relative path (e.g. .) as the value for program, so the client (vscode) can request like "go build . from the current specified directory - either in the directory the dlv runs with or buildDir(TODO) specifies.

Personally, I prefer the option 2 which gives more flexibility to clients.

[polinasok]

Dlv-dap already can handle a relative program path, just like dlv cli - same helper library is used to build in both cases. The absolute path is enforced in the extension, but it doesn't have to be.
