Not aware of any changes, but note that rust-analyzer does not handle debugging Rust code; it only integrates with existing debugging tools. It might be that your code is not being built with debug info.

You are right but I gelt like to report a change that happened right after the RA update and that disappeared with the downgrade. Maybe someone has an idea of what's going on..

There was a change to the debug task here cb523fc which broke some stuff, and another followup in https://github.com/rust-lang/rust-analyzer/blob/master/editors/code/src/debug.ts which fixed things btu this might still have changed some behavior

Just a side note, I still have the same issue with RA v2037 and codeLLDB, in vscode.

Anyone else experience this ? I would like to not be stuck in v2020.

I think I found the issue on our side

@Veykril Just installed v2045 and the problem still occurs.

Thanks for checking again, I'll take another look. What debugging extension are you using?

@Veykril : many thanks to you. I use codeLLDB. Every extensions are up to date on my system.

Hmm, breakpoints do work for me on the latest release 😕

I will try with a naked vscode and see. I will report in two/three hours. Thanks a lot

Ok it works on a naked installation.
I will report the setting(s) that mess everything, in case anyone else has the same issue.
Then I will close this issue.

@Veykril found the culprit!

it's "rust-analyzer.runnables.extraArgs" coupled with "release".

in my setting.json I had:

"rust-analyzer.runnables.extraArgs": [
        "--release"
]

that launched the optimized version of my code when clicking the "release" inlay button above my test.
Now, it seems that it is working differently and
replaces:

"rust-analyzer.runnables.extraTestBinaryArgs": [
        "--show-output",
        "--nocapture"
],

which is a differing behavior from v2020. It is as if extraTestBinaryArgs was overwritten by the extraArgs.
It's in the inlay button management that the issue lies.

When removing extraArgs, a click on the debug button works fine, as usual.
