ICE: Failed to normalize <std::option::Option<&std::option::Option<usize>> as std::iter::Iterator>::Item #8662

irevoire · 2022-04-08T11:10:08Z

Hello, we encounter a ICE with Clippy in our CI.
I can't reproduce the error locally though.
You can look at it here: https://github.com/meilisearch/meilisearch/runs/5883955221?check_suite_focus=true
Hope that helps!

Seeing this in our CI too - ours is a proprietary codebase so I can't share the code, but here's the full error:

I think this was fixed with #8602. Can you check once 2022-04-08 is available?

Still seeing a similar error with 2022-04-08:

Update: cargo clippy passes successfully on that same codebase, with Rust nightly 2022-04-12.

This is our monthly toolchain upgrade to the latest stable version. Since iotedge/edgelet is a binary package, we want to be tracking Rust compiler releases closely in the event a stdlib vulnerability is found. We do not pin to "stable", however, since that has caused pipeline breakage when some code patterns are made illegal (like in the upgrade from 1.47 to 1.48 [^0]) or, more often, clippy lints are added. - Change from `cloned()` to `copied()` since we can and to work around ICE: rust-lang/rust-clippy#8662 [^0]: https://github.com/rust-lang/rust/blob/master/RELEASES.md#compatibility-notes-11 Namely, the point on `mem::uninitialized`. ## Azure IoT Edge PR checklist:

I guess the sync was a day or two late then.

Thanks for the reports!

I'm closing this because it seems to be resolved in #8662 (comment). If any problems happens about this, feel free to reopen or comment.

EdgeHub watchdog has to shell out to sleep rather than call `thread::sleep()` to bypass a bug in rust. Logged a bug with rust repo. 4. Various retries added in E2E test code to get around problems caused by dotnet 6. Logged bugs with SDK team where appropriate. 5.

Hello, I don't know if we're supposed to do something specific, but it's still failing in the CI for us with the action-rs thingy;
https://github.com/meilisearch/meilisearch/runs/6097361418?check_suite_focus=true

Jarcho · 2022-04-20T16:24:37Z

The fix is only on nightly, not stable.

Fuuzetsu · 2022-04-26T07:13:21Z

Are clippy point-releases a thing or does everyone affected by this that's not using nightly compiler have to wait for Rust 1.61?

ETKNeil · 2022-05-11T07:41:06Z

Minimal code example for my issue

use std::collections::HashMap;

struct Test{
    map:    HashMap<String, Option<u32>>,
}

impl Test{
    pub fn get_or(&self, identity: &String) -> Option<u32> {
        self.map.get(identity).cloned().flatten()
    }
}

fasterthanlime · 2022-05-20T08:28:09Z

This is present again in Rust 1.61.0:

Hey @giraffate I don't have the right to re-open the issue, feel free to do it for me 👍

Also, it seems like the bug has been fixed for us (= https://github.com/meilisearch/MeiliSearch), the CI is working again.

it seems like the bug has been fixed for us

Yeah so upon further inspection, that bug I'm hitting now looks very similar but it hit different parts of the code than the previous report. And it was only two code paths and I could easily work around it. I should file a separate report with some repro code.

giraffate · 2022-05-23T00:06:28Z

Thanks for another report!

Does it reproduce in latest nightly? If so, it would be good to file a new issue with reproduction.

The issue has been fixed in the latest release of rust. See rust-lang/rust-clippy#8662 Fix #2305

Actually it doesn't! nightly 4cbaac699 / 2022-05-25 doesn't crash there. Yay!
