…elid,xFrednet Update pulldown-cmark version to 0.9 Fixes rust-lang#92206. r? `@camelid`
Clippy helpfully warns about code like this, telling you that you
probably meant "write_all":
fn say_hi<W:Write>(w: &mut W) {
w.write(b"hello").unwrap();
}
This patch attempts to extend the lint so it also covers this
case:
async fn say_hi<W:AsyncWrite>(w: &mut W) {
w.write(b"hello").await.unwrap();
}
(I've run into this second case several times in my own programming,
and so have my coworkers, so unless we're especially accident-prone
in this area, it's probably worth addressing?)
This patch covers the Async{Read,Write}Ext traits in futures-rs,
and in tokio, since both are quite widely used.
changelog: [`unused_io_amount`] now supports AsyncReadExt and AsyncWriteExt.
This improves the quality of the genrated output and makes it more in line with other lint messages. changelog: [`unused_io_amount`]: Improve help text

Extend unused_io_amount to cover async io.
Clippy helpfully warns about code like this, telling you that you
probably meant "write_all":
fn say_hi<W:Write>(w: &mut W) {
w.write(b"hello").unwrap();
}
This patch attempts to extend the lint so it also covers this
case:
async fn say_hi<W:AsyncWrite>(w: &mut W) {
w.write(b"hello").await.unwrap();
}
(I've run into this second case several times in my own programming,
and so have my coworkers, so unless we're especially accident-prone
in this area, it's probably worth addressing?)
Since this is my first attempt at a clippy patch, I've probably
made all kinds of mistakes: please help me fix them? I'd like
to learn more here.
Open questions I have:
* Should this be a separate lint from unused_io_amount? Maybe
unused_async_io_amount? If so, how should I structure their
shared code?
* Should this cover tokio's AsyncWrite too?
* Is it okay to write lints for stuff that isn't part of
the standard library? I see that "regex" also has lints,
and I figure that "futures" is probably okay too, since it's
an official rust-lang repository.
* What other tests are needed?
* How should I improve the code?
Thanks for your time!

…earth fix [`redundant_closure`] fp with `Rc<F>`/`Arc<F>` fixes rust-lang#8073 changelog: don't trigger [`redundant_closure`] on `Arc<F>` or `Rc<F>`
The `wrong_self_convention` lint uses a `SelfKind` type to decide
whether a method has the right kind of "self" for its name, or whether
the kind of "self" it has makes its name confusable for a method in
a common trait. One possibility is `SelfKind::No`, which is supposed
to mean "No `self`".
Previously, SelfKind::No matched everything _except_ Self, including
references to Self. This patch changes it to match Self, &Self, &mut
Self, Box<Self>, and so on.
For example, this kind of method was allowed before:
```
impl S {
// Should trigger the lint, because
// "methods called `is_*` usually take `self` by reference or no `self`"
fn is_foo(&mut self) -> bool { todo!() }
}
```
But since SelfKind::No matched "&mut self", no lint was triggered
(see rust-lang#8142).
With this patch, the code above now gives a lint as expected.
Fixes rust-lang#8142

wrong_self_convention: Match `SelfKind::No` more restrictively

…xFrednet [`erasing_op`] lint ignored when operation `Output` type is different from the type of constant `0` fixes rust-lang#7210 changelog: [`erasing_op`] lint ignored when operation `Output` type is different from the type of constant `0`
Remove `NullOp::Box` Follow up of rust-lang#89030 and MCP rust-lang/compiler-team#460. ~1 month later nothing seems to be broken, apart from a small regression that rust-lang#89332 (1aac85bb716c09304b313d69d30d74fe7e8e1a8e) shows could be regained by remvoing the diverging path, so it shall be safe to continue and remove `NullOp::Box` completely. r? `@jonas-schievink` `@rustbot` label T-compiler

changelog: none Sorry, this is a big one. A lot of interrelated changes and I wanted to put the new utils to use to make sure they are somewhat battle-tested. We may want to divide some of the lint-specific refactoring commits into batches for smaller reviewing tasks. I could also split into more PRs. Introduces a bunch of new utils at `clippy_utils::macros::...`. Please read through the docs and give any feedback! I'm happy to introduce `MacroCall` and various functions to retrieve an instance. It feels like the missing puzzle piece. I'm also introducing `ExpnId` from rustc as "useful for Clippy too". `@rust-lang/clippy` Fixes rust-lang#7843 by not parsing every node of macro implementations, at least the major offenders. I probably want to get rid of `is_expn_of` at some point.

Partially stabilize `maybe_uninit_extra`
This covers:
```rust
impl<T> MaybeUninit<T> {
pub unsafe fn assume_init_read(&self) -> T { ... }
pub unsafe fn assume_init_drop(&mut self) { ... }
}
```
It does not cover the const-ness of `write` under `const_maybe_uninit_write` nor the const-ness of `assume_init_read` (this commit adds `const_maybe_uninit_assume_init_read` for that).
FCP: rust-lang#63567 (comment).

…shtriplett fs: Use readdir() instead of readdir_r() on Linux readdir() is preferred over readdir_r() on Linux and many other platforms because it more gracefully supports long file names. Both glibc and musl (and presumably all other Linux libc implementations) guarantee that readdir() is thread-safe as long as a single DIR* is not accessed concurrently, which is enough to make a readdir()-based implementation of ReadDir safe. This implementation is already used for some other OSes including Fuchsia, Redox, and Solaris. See rust-lang#40021 for more details. Fixes rust-lang#86649.
