Introduce linter for diagnostic messages by hkmatsumoto · Pull Request #89455 · rust-lang/rust

hkmatsumoto · 2021-10-02T04:05:22Z

Sometimes, contributors add diagnostics not practicing the diagnostic message convention and overlooked by reviewers. This PR adds a linter for diagnostic messages to preemptively warn such diagnostics and lighten the burden of reviewers.

Please loop me in on the bootstrap details here when this is ready for review.

hkmatsumoto · 2021-10-03T06:59:55Z

There are cases where it's not clear to say ok or not okay.
To be or not to be, that is the question.
to be or not to be, that is the question.

Let there be light: and there was light.

Any thoughts on these?

Any thoughts on these?

I'd lean towards the last of each example.

estebank · 2021-10-04T15:04:37Z

The code changes in this repo look good, but am slightly concerned about the out of repo linter. That being said, I think that this linter will be useful.

Mark-Simulacrum · 2021-10-04T15:09:33Z

I don't understand why it's optional to check diagnostic messages -- shouldn't we always do that in compiletest, not gated on a CLI option?

Is there a quick link to the lint rules in diaglint? It looks like we're using a default set right now, but I'm not quickly finding docs on what that set actually is. Can you show an example of a potential lint message?

Fair enough, we can make it default and can manually ignore some lint if needed.

Currently I haven't written any docs, but the lints are defined here. These lints are inspired from here

Mark-Simulacrum · 2021-10-09T16:54:21Z

I'll leave it up to @estebank to decide, but I think this probably should receive some T-compiler attention (or at least wg-diagnostics). I'm not personally a fan of out-of-tree lints against our lint definitions -- generally, I would expect us to do that in-tree. Bringing in extra dependencies and another diagnostics engine also feels a little too much, particularly since it's in the critical path for all "first" compiletest invocations rather than some separate not-run-by-users suite. (To be clear, I don't think we should move it out of compiletest; that seems like the right place. It's just that the cost feels higher than needed).

Can you show an example of a potential lint message?

I asked this earlier, but I don't think I've seen how this looks in practice -- maybe I missed it? I would want to make sure if we are linting there is a clear message included on (a) how to disable the lint and (b) what to do to fix the lint, if desired.

Ping from triage: @hkmatsumoto tests are failing.

apiraino · 2021-12-09T15:38:23Z

mentioned in today's T-compiler meeting on Zulip, perhaps this needs a bit more discussion during a steering meeting or drafting an MCP

hkmatsumoto · 2021-12-10T16:12:29Z

I guess having a meeting is very good to reorganize the pros and cons. I'm not very sure if I can speak/write English fast enough for smooth conversations, though.
Either way, I plan to draft an MCP in the year-end and new-year holidays.

@hkmatsumoto apologies for my poor communication and vague comment :) (I've just dropped a note to let everyone know this is progressing). Don't worry ! In case your input is needed, the team will gladly help you sort out what is needed.

thanks for your patience and contributions! :)
