Rollup merge of #65977 - ohadravid:fix-incorrect-diagnostics-with-an-associated-type, r=estebank

Fix incorrect diagnostics for expected type in E0271 with an associated type

With code like the following code:

```rust
#[derive(Debug)]
struct Data {}

fn do_stuff<'a>(iterator: impl Iterator<Item = &'a Data>) {
    for item in iterator {
        println!("{:?}", item)
    }
}

fn main() {
    let v = vec![Data {}];

    do_stuff(v.into_iter());
}
```

the diagnostic (in nightly & stable) wrongly complains about the expected type:

```
error[E0271]: type mismatch resolving `<std::vec::IntoIter<Data> as std::iter::Iterator>::Item == &Data`
  --> src/main.rs:15:5
   |
5  | fn do_stuff<'a>(iterator: impl Iterator<Item = &'a Data>) {
   |    --------                             --------------- required by this bound in `do_stuff`
...
15 |     do_stuff(v.into_iter());
   |     ^^^^^^^^ expected struct `Data`, found &Data
   |
   = note: expected type `Data`
              found type `&Data`
```

This PR fixes this issue by flipping the expected/actual values where appropriate, so it looks like this:

```
error[E0271]: type mismatch resolving `<std::vec::IntoIter<Data> as std::iter::Iterator>::Item == &Data`
  --> main.rs:15:5
   |

15 |     do_stuff(v.into_iter());
   |     ^^^^^^^^ expected &Data, found struct `Data`
   |
   = note: expected type `&Data`
              found type `Data`
```

This improves the output of a lot of existing tests (check out `associated-types-binding-to-type-defined-in-supertrait`!).

The only change which I wasn't too sure about is in the test `associated-types-overridden-binding-2`, but I think it's an improvement and the underlying problem is with handling of `trait_alias`.

This is my first contribution to the Rust project, so I apologize if I'm not doing things the right way.

The PR fixes #64169. It adds a lint and tests for unnecessary parentheses around types. I've run `tidy` and `rustfmt` &mdash; I'm not totally sure it worked right, though &mdash; and I've tried to follow the instructions linked in the readme.

I tried to think through all the variants of `ast::TyKind` to find exceptions to this lint, and I could only find the one mentioned in the original issue, which concerns types with `dyn`. I'm not a Rust expert, thought, so I may well be missing something.

There's also a problem with getting this to build. The new lint catches several things in the, e.g., `core`. Because `x.py` seems to build with an equivalent of `-Werror`, what would have been warnings cause the build to break. I got it to build and the tests to pass with `--warnings warn` on my `x.py build` and `x.py test` commands.

Fix `-Zunpretty=mir-cfg` to render multiple items

`-Zunpretty=mir-cfg` outputs DOT to stdout for all items being compiled. However, it puts all of these items in separate `digraph`s, which means the result of redirecting that output to a file is not valid. Most dot renderers (I have tried `dot` and `xdot`) cannot render the output.

This PR checks to see if `write_mir_graphviz` will  process multiple items, and writes them each as a `subgraph` in a single, top-level `digraph`. As a result, DOT can be viewed without manually editing the output file. The output is unchanged when printing a single item (e.g.`-Zunpretty=mir-cfg=item_name`).

Here's the output of `xdot` for a rust file containing three items:

The borders are a result of the nonstandard–but well-supported–[`cluster` prefix](https://graphviz.gitlab.io/_pages/doc/info/lang.html) (search for "Subgraphs and Clusters"). They will not appear if your renderer does not support this extension, but the graph will still render properly.

Update comments re type parameter hack in object safety

To check if a method's receiver type is object safe, we create a new receiver type by substituting in a bogus type parameter (let's call it `U`) for `Self`, and checking that the unmodified receiver type implements `DispatchFromDyn<receiver type with Self = U>`. It would be better to use `dyn Trait` directly, and the only reason we don't is because it triggers another check that `Trait` is object safe, resulting in a query cycle. Once the feature `object_safe_for_dispatch` (tracking issue https://github.com/rust-lang/rust/issues/43561) is stabilized, this will no longer be the case, and we'll be able to use `dyn Trait` as the unsized `Self` type. I've updated the comments in object_safety.rs accordingly.

4 years agoci: move toolstates.json to /tmp/toolstate/ and docker mount it
Pietro Albini [Wed, 30 Oct 2019 18:41:22 +0000 (19:41 +0100)]
ci: move toolstates.json to /tmp/toolstate/ and docker mount it

Before this commit toolstates.json was stored in /tmp and it wasn't
mounted outside the build container. That caused uploading the file in
the upload-artifacts task to fail, as the file was missing on the host.

Mounting /tmp/toolstates.json alone is not the best approach: if the
file is missing when the container is started the Docker engine will
create a *directory* named /tmp/toolstates.json.

The Docker issue could be solved by pre-creating an empty file named
/tmp/toolstates.json, but doing that could cause problems if bootstrap
fails to generate the file and the toolstate scripts receive an empty
JSON.

The approach I took in this commit is to instead mount a /tmp/toolstate
directory inside Docker, and create the toolstates.json file in it. That
also required a small bootstrap change to ensure the directory is
created if it's missing.
