This PR aims at uplifting the clippy::undropped_manually_drops lint.

undropped_manually_drops

(deny-by-default)

The undropped_manually_drops lint check for calls to std::mem::drop with a value of std::mem::ManuallyDrop which doesn't drop.

Example

struct S;
drop(std::mem::ManuallyDrop::new(S));

Explanation

ManuallyDrop does not drop it's inner value so calling std::mem::drop will not drop the inner value of the ManuallyDrop either.


Mostly followed the instructions for uplifting an clippy lint described here: #99696 (review)

Hey! It looks like you've submitted a new PR for the library teams!

If this PR contains changes to any rust-lang/rust public library APIs then please comment with @rustbot label +T-libs-api -T-libs to tag it appropriately. If this PR contains changes to any unstable APIs please edit the PR description to add a link to the relevant API Change Proposal or create one if you haven't already. If you're unsure where your change falls no worries, just leave it as is and the reviewer will take a look and make a decision to forward on if necessary.

Examples of T-libs-api changes:

  • Stabilizing library features
  • Introducing insta-stable changes such as new implementations of existing stable traits on existing stable types
  • Introducing new or changing existing unstable library APIs (excluding permanently unstable features / features without a tracking issue)
  • Changing public documentation in ways that create new stability guarantees
  • Changing observable runtime behavior of library APIs

ManuallyDrop doesn't not drop it's inner value

I think this part of the description is incorrect? Should it be "ManuallyDrop does not drop its inner value ..."?

Didn't I see some lints go by recently that lint for using drop on things that are Copy? Might it make sense for this to be just part of that lint? Something like "promised it won't be needs_drop" instead of Copy?

Or if this is worth adding separately, maybe it would make sense to give it a higher default level as a "this is a specific mistake that people make" deny lint rather than a "this is useless" warn lint?

Didn't I see some lints go by recently that lint for using drop on things that are Copy?

Yes, it was #109732

Might it make sense for this to be just part of that lint? Something like "promised it won't be needs_drop" instead of Copy?

Well, it uplifted 4 lints, clippy::{drop,forget}_{ref,copy}. They could maybe be merged into one or two lint(s) if desired. I could see a reason for grouping by method but don't think this lint should be part of any of them since undropped_manually_drops detects obvious mistake while the other aren't not at the same level of "obvious mistake" (dropping a ref isn't wrong it's just useless, dropping a ManuallyDrop is useless but also surely a mistake).

Or if this is worth adding separately, maybe it would make sense to give it a higher default level as a "this is a specific mistake that people make" deny lint rather than a "this is useless" warn lint?

Yes, sure. My take on the default level was "does it cause UB? yes -> deny; no -> warn" but since this lint catch's a so obvious mistake that no-one would have ever wrote this intentionally, it could make sense to make it deny-by-default.

@scottmcm

Yeah, we have a couple of other deny-by-default lints like that. For example,

  • unused binding from match pattern: warning
  • unused binding from match pattern, but spelled exactly the same as a variant of the type it's matching against: deny (and suggest replacing A => with Foo::A => )

When there's a super-specific suggestion we can give (here to use ManuallyDrop::drop instead of mem::drop) because it's a known pattern, I think deny-by-default makes good sense.

Make sense, I will change it to deny-by-default.

(btw, the suggestion here is ManuallyDrop::into_inner not ManuallyDrop::drop as the lint only triggers on owned ManuallyDrop, the ref cases and handled by the other lints)

  • only primary benchmark to regress was helloworld (3 incr check variants), and not by all that much (relatively speaking)
  • secondary regressions were solely to unify-linearly, await-call-tree, token-stream-stress.
  • impact seems acceptable (one expects new lint to add some amount of extra work, and I wouldn't be surprised if this is actually noise,. given Misc HIR typeck type mismatch tweaks #112116 above).
  • marking as triaged.

Uplift `clippy::undropped_manually_drops` lint

This PR aims at uplifting the `clippy::undropped_manually_drops` lint.

## `undropped_manually_drops`

(warn-by-default)

The `undropped_manually_drops` lint check for calls to `std::mem::drop` with a value of `std::mem::ManuallyDrop` which doesn't drop.

### Example

```rust
struct S;
drop(std::mem::ManuallyDrop::new(S));
```

### Explanation

`ManuallyDrop` does not drop it's inner value so calling `std::mem::drop` will not drop the inner value of the `ManuallyDrop` either.

Cargo
-----
- Enable `-Zdoctest-in-workspace` by default. When running each documentation
  test, the working directory is set to the root directory of the package the
  test belongs to.

- Add support of the "default" keyword to reset previously set `build.jobs`
  parallelism back to the default.

Compatibility Notes
-------------------
- [Alter `Display` for `Ipv6Addr` for IPv4-compatible addresses](rust-lang/rust#112606)
- Cargo changed feature name validation check to a hard error. The warning was
  added in Rust 1.49. These extended characters aren't allowed on crates.io, so
  this should only impact users of other registries, or people who don't publish
  to a registry.
