enableSearchInput was called from two places:
- setupSearchLoader
- addSearchOptions, which is itself called from setupSearchLoader only
This commit can safely get rid of the addSearchOptions calls entirely,
and since the setupSearchLoader call is immediately preceded by other
method calls on search_input, there's no need to check if it's set.
1. I added `--test` based on review feedback from simulacrum: I decided I would
rather include such extra context than get confused later on by its absence.
(However, I chose to encode it differently than how `[RUSTC-TIMING]` does... I
don't have much basis for doing so, other than `--test` to me more directly
reflects what it came from.)
2. I also decided to include `[RUSTC-SHIM]` at start of all of these lines
driven by the verbosity level, to make to clear where these lines of text
originate from. (Basically, I skimmed over the output and realized that a casual
observer might not be able to tell where this huge set of new lines were coming
from.)
This commit fixes an issue pointed out in #82758 where LTO changed the
behavior of a program. It turns out that LTO was not at fault here, it
simply uncovered an existing bug. The bindings to
`__wasilibc_find_relpath` assumed that the relative portion of the path
returned was always contained within thee input `buf` we passed in. This
isn't actually the case, however, and sometimes the relative portion of
the path may reference a sub-portion of the input string itself.
The fix here is to use the relative path pointer coming out of
`__wasilibc_find_relpath` as the source of truth. The `buf` used for
local storage is discarded in this function and the relative path is
copied out unconditionally. We might be able to get away with some
`Cow`-like business or such to avoid the extra allocation, but for now
this is probably the easiest patch to fix the original issue.
Great for spotting false positives/broken suggestions of applicable lints.
There are false positives though becasue I'm not sure yet how to silence rustc warnings while keeping clippy warnings.
Sometimes rustc makes a suggestion that fails to apply and the implementation does not differenciate between clippy and rustc warnings when applying lint suggestions.

Remove unused code from main.js
It looks like `lev_distance` was used in a very old version of the function, since it was written but never read, and Blame reports that it was added before the `checkGenerics` function header itself.
`convertHTMLToPlaintext` is was removed by 768d5e9509
Add diagnostic item to `Default` trait
This PR adds diagnostic item to `Default` trait to be used by rust-lang/rust-clippy#6562 issue.
Also fixes the obsolete path to the `symbols.rs` file in the comment.
Add assert_matches macro.
This adds `assert_matches!(expression, pattern)`.
Unlike the other asserts, this one ~~consumes the expression~~ may consume the expression, to be able to match the pattern. (It could add a `&` implicitly, but that's noticable in the pattern, and will make a consuming guard impossible.)
See https://github.com/rust-lang/rust/issues/62633#issuecomment-790737853
This re-uses the same `left: .. right: ..` output as the `assert_eq` and `assert_ne` macros, but with the pattern as the right part:
assert_eq:
```
assertion failed: `(left == right)`
left: `Some("asdf")`,
right: `None`
```
assert_matches:
```
assertion failed: `(left matches right)`
left: `Ok("asdf")`,
right: `Err(_)`
```

Add {BTreeMap,HashMap}::try_insert
`{BTreeMap,HashMap}::insert(key, new_val)` returns `Some(old_val)` if the key was already in the map. It's often useful to assert no duplicate values are inserted.
We experimented with `map.insert(key, val).unwrap_none()` (https://github.com/rust-lang/rust/issues/62633), but decided that that's not the kind of method we'd like to have on `Option`s.
`insert` always succeeds because it replaces the old value if it exists. One could argue that `insert()` is never the right method for panicking on duplicates, since already handles that case by replacing the value, only allowing you to panic after that already happened.
This PR adds a `try_insert` method that instead returns a `Result::Err` when the key already exists. This error contains both the `OccupiedEntry` and the value that was supposed to be inserted. This means that unwrapping that result gives more context:
```rust
map.insert(10, "world").unwrap_none();
// thread 'main' panicked at 'called `Option::unwrap_none()` on a `Some` value: "hello"', src/main.rs:8:29
```
```rust
map.try_insert(10, "world").unwrap();
// thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value:
// OccupiedError { key: 10, old_value: "hello", new_value: "world" }', src/main.rs:6:33
```
It also allows handling the failure in any other way, as you have full access to the `OccupiedEntry` and the value.
`try_insert` returns a reference to the value in case of success, making it an alternative to `.entry(key).or_insert(value)`.

Avoid unnecessary Vec construction in BufReader
As mentioned in #80460, creating a `Vec` and calling `Vec::into_boxed_slice()` emits unnecessary calls to `realloc()` and `free()`. Updated the code to use `Box::new_uninit_slice()` to create a boxed slice directly. I think this also makes it more explicit that the initial contents of the buffer are uninitialized.

Improved IO Bytes Size Hint
After trying to implement better `size_hint()` return values for `File` in [this PR](https://github.com/rust-lang/rust/pull/81044) and changing to implementing it for `BufReader` in [this PR](https://github.com/rust-lang/rust/pull/81052), I have arrived at this implementation that provides tighter bounds for the `Bytes` iterator of various readers including `BufReader`, `Empty`, and `Chain`.
Unfortunately, for `BufReader`, the size_hint only improves after calling `fill_buffer` due to it using the contents of the buffer for the hint. Nevertheless, the the tighter bounds should result in better pre-allocation of space to handle the contents of the `Bytes` iterator.
Closes#81052
resolve: Reduce scope of `pub_use_of_private_extern_crate` deprecation lint
This lint was deny-by-default since July 2017, crater showed 7 uses on crates.io back then (https://github.com/rust-lang/rust/pull/42894#issuecomment-311921147).
Unfortunately, the construction `pub use foo as bar` where `foo` is `extern crate foo;` was used by an older version `bitflags`, so turning it into an error causes too many regressions.
So, this PR reduces the scope of the lint instead of turning it into a hard error, and only turns some more rarely used components of it into errors.
Implement NOOP_METHOD_CALL lint
Implements the beginnings of https://github.com/rust-lang/lang-team/issues/67 - a lint for detecting noop method calls (e.g, calling `<&T as Clone>::clone()` when `T: !Clone`).
This PR does not fully realize the vision and has a few limitations that need to be addressed either before merging or in subsequent PRs:
* [ ] No UFCS support
* [ ] The warning message is pretty plain
* [ ] Doesn't work for `ToOwned`
The implementation uses [`Instance::resolve`](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_middle/ty/instance/struct.Instance.html#method.resolve) which is normally later in the compiler. It seems that there are some invariants that this function relies on that we try our best to respect. For instance, it expects substitutions to have happened, which haven't yet performed, but we check first for `needs_subst` to ensure we're dealing with a monomorphic type.
Thank you to ```@davidtwco,``` ```@Aaron1011,``` and ```@wesleywiser``` for helping me at various points through out this PR ❤️.
Inherit `#[stable(..)]` annotations in enum variants and fields from its item
Lint changes for #65515. The stdlib will have to be updated once this lands in beta and that version is promoted in master.
It looks like `lev_distance` was used in a very old version of the function,
since it was written but never read, and Blame reports that it was added
before the `checkGenerics` function header itself.
`convertHTMLToPlaintext` is was removed by 768d5e9509
