• Fix Failed to map Rust stdlib sources when debugging in Windows #18782

[lnicola]

Thanks!

Kindly ping @davidbarsky on why it was changed in the first place (f25cb19). Is it intentional for lldb-dap or just an oversight?

[davidbarsky]

I don’t remember. In my testing, I don’t think either lldb-dap or CodeLLDB needed the commit hash, but I wasn’t particularly thorough in my testing.

[lnicola]

To me, it looks like lldb-dap just wants an array, and the rest of the change was just a refactoring.

[lnicola]

By the way, llvm/llvm-project#106919 is now merged.

[davidbarsky]

I think that change was merged when I wrote the commit where I refactored this code, but there wasn’t an lldb (or lldb-dap) release containing said changes. I think there might be one now?

[lnicola]

Yeah, there is.
