6384dca100 Auto merge of #90439 - m-ou-se:thread-is-running, r=Mark-Simulacrum
Add JoinHandle::is_running.

This adds:
```rust
impl<T> JoinHandle<T> {
    /// Checks if the the associated thread is still running its main function.
    ///
    /// This might return `false` for a brief moment after the thread's main
    /// function has returned, but before the thread itself has stopped running.
    pub fn is_running(&self) -> bool;
}
```
The usual way to check if a background thread is still running is to set some atomic flag at the end of its main function. We already do that, in the form of dropping an Arc which will reduce the reference counter. So we might as well expose that information.

This is useful in applications with a main loop (e.g. a game, gui, control system, ..) where you spawn some background task, and check every frame/iteration whether the background task is finished to .join() it in that frame/iteration while keeping the program responsive.

CI: Use ubuntu image to download openssl, curl sources, cacert.pem for x86 dist builds

The dist-x86_64 and dist-i686 docker builds are failing again (see [try build](https://github.com/rust-lang-ci/rust/runs/4060836540?check_suite_focus=true)) because python.org renewed its certificate with a CA cert that is too new for debian:6.

In order to solve this once and for all this PR moves the curl and openssl downloads to a new  ubuntu:20.04 "stage-0" docker build and copies the downloaded tarballs over to build them in the "stage-1" debian:6 context. It also downloads the cacert.pem file from the curl website and uses it by pointing the `CURL_CA_BUNDLE` environment variable to it.

After updating the minimum required LLVM version to 12 we can use
apple-a14 as that is closer in features to the Apple M1 than the A12.
Once the minimum required LLVM version is updated to 13 we can use
apple-m1.

bb1cf72999 Update CHANGELOG to include separated_literal_suffix 2021-11-01 22:26:38 +08:00
Dharma Saputra Wijaya
1085df58ac Add separated_literal_suffix as an alternative for
`unseparated_literal_suffix`

This commit adds a configuration `literal-suffix-style` to enforce a
specific style for unseparated_literal_suffix. The configuration accepts
two values:
- "separated"
    enforce all literals to be written separately (e.g. `123_i32`)
- "unseparated"
    enforce all literals to be written as unseparated (e.g. `123i32`)

Not specifying a value means that there is no preference on style and
any style should not be warned.

c03cab3fd0 Fix RefCell BorrowMut error in DocVisitor
Until `external_traits` is cleaned up (i.e., no longer behind a
`RefCell`), `DocVisitor` will have to `take` `external_traits` -- just
like `DocFolder` -- to prevent `RefCell` runtime errors.

5a9bbba280 rustdoc: Add DocVisitor
`DocFolder` allows transforming the docs, accomplished by making its
methods take and return types by-value. However, several of the rustdoc
`DocFolder` impls only *visit* the docs; they don't change anything.
Passing around types by-value is thus unnecessary, confusing, and
potentially inefficient for those impls.

`DocVisitor` is very similar to `DocFolder`, except that its methods
take shared references and return nothing (i.e., the unit type). This
should both be more efficient and make the code clearer.

There is an additional reason to add `DocVisitor`, too. As part of my
cleanup of `external_traits`, I'm planning to add a `fn cache(&mut self)
-> &mut Cache` method to `DocFolder` so that `external_traits` can be
retrieved explicitly from the `Cache`, rather than implicitly via
`Crate.external_traits` (which is an `Rc<RefCell<...>>`). However, some
of the `DocFolder` impls that could be turned into `DocVisitor` impls
only have a shared reference to the `Cache`, because they are used
during rendering. (They have to access the `Cache` via
`html::render::Context.shared.cache`, which involves an `Rc`.)

Since `DocVisitor` does not mutate any of the types it's visiting, its
equivalent `cache()` method will only need a shared reference to the
`Cache`, avoiding the problem described above.

537b82cfad rustdoc: Remove unnecessary clone in DocFolder
Also, contrary to the comment, the clone is not that small, since
`Variant` contains `Item`s, which are quite large when you factor in
both stack- and heap-allocated memory.

Test that promotion follows references when looking for drop

Noticed that this wasn't covered by any of existing tests.

The const checking and const qualification, which currently shares the
implementation with promotion, will likely need a different behaviour
here (see issue #90193).

Rollup merge of #90349 - willcrichton:example-analyzer, r=jyn514
Fix rare ICE during typeck in rustdoc scrape_examples

While testing the `--scrape-examples` extension on the [wasmtime](https://github.com/bytecodealliance/wasmtime) repository, I found some additional edge cases. Specifically, when asking to typecheck a body containing a function call, I would sometimes get an ICE if:
* The body doesn't exist
* The function's HIR node didn't have a type

This adds checks for both of those conditions.

(Also this updates a test to check that the sources of a reverse-dependency are correctly generated and linked.)

rustdoc: remove flicker during page load

The search bar has a `:disabled` style that makes it grey, which creates a distracting flicker from grey to white when the page finishes loading. The search bar should stay the same color throughout page load.

A blank white search bar might create an incorrect impression for users with JS turned off. Since they can't use the search functionality, I've hidden the search bar in noscript.css.

Fixes #90246
