2019-07-09Rollup merge of #62494 - sinkuu:unused_deps, r=alexcrichtonMazdak Farrokhzad-3/+0
Remove unused dependencies
2019-07-09Rollup merge of #62403 - SimonSapin:concat, r=alexcrichtonMazdak Farrokhzad-74/+76
Replace SliceConcatExt trait with inherent methods and SliceConcat helper trait Before this change `SliceConcatExt` was an unstable extension trait with stable methods. It was in the libstd prelude, so that its methods could be used on the stable channel. This replaces it with inherent methods, which can be used without any addition to the prelude. Since the methods are stable and very generic (with for example a return type that depends on the types of parameters), an helper trait is still needed. But now that trait does not need to be in scope for the methods to be used. Removing this depedency on the libstd prelude allows the methods to be used in `#![no_std]` crate that use liballoc, which does not have its own implicitly-imported prelude.

2019-07-09Rollup merge of #60458 - KodrAus:debug_map_entry, r=alexcrichtonMazdak Farrokhzad-25/+238
Add key and value methods to DebugMap Implementation PR for an active (not approved) RFC: https://github.com/rust-lang/rfcs/pull/2696. Add two new methods to `std::fmt::DebugMap` for writing the key and value part of a map entry separately: ```rust impl<'a, 'b: 'a> DebugMap<'a, 'b> { pub fn key(&mut self, key: &dyn Debug) -> &mut Self; pub fn value(&mut self, value: &dyn Debug) -> &mut Self; } ``` I want to do this so that I can write a `serde::Serializer` that forwards to our format builders, so that any `T: Serialize` can also be treated like a `T: Debug`.

2019-07-08Auto merge of #62473 - timvermeulen:is_sorted_by_key, r=scottmcmbors-5/+5
Only call the closure parameter of Iterator::is_sorted_by_key once per item See https://github.com/rust-lang/rust/issues/53485#issuecomment-472314004. This changes `Iterator::is_sorted_by_key` to only call the given closure once for each item, which allows us to pass the items to the closure by value instead of by reference. **Important**: `is_sorted_by_key` for slices and slice iterators is now no longer implemented in terms of the custom `slice::Iter::is_sorted_by` implementation. It's a trade-off: we could forward `slice::Iter::is_sorted_by_key` to it directly for potential SIMD benefits, but that would mean that the closure is potentially called twice for (almost) every element of the slice.

2019-07-08Rollup merge of #62477 - petrhosek:unwind-bootstrap, r=cramertjMazdak Farrokhzad-8/+15
Re-add bootstrap attribute to libunwind for llvm-libunwind feature This was removed in 8a7dded, but since #62286 hasn't yet made it into beta, this is breaking the build with llvm-libunwind feature enabled. Furthemore, restrict the link attribute to Fuchsia and Linux, matching the logic in build.rs since llvm-libunwind feature isn't yet supported on other systems.

Check if the archive has already been added to avoid duplicates This avoids adding archives multiple times, which results in duplicate objects in the resulting rlib, leading to symbol collision and link failures. This could happen when crate contains multiple link attributes that all reference the same archive.
2019-07-07Rollup merge of #62213 - QuietMisdreavus:cfg-doctest, r=GuillaumeGomezMazdak Farrokhzad-4/+78
rustdoc: set cfg(doctest) when collecting doctests Note: This PR builds on top of https://github.com/rust-lang/rust/pull/61199; only the last commit is specific to this PR. As discussed in https://github.com/rust-lang/rust/pull/61199, we want the ability to isolate items to only when rustdoc is collecting doctests, but we can't use `cfg(test)` because of libcore's `#![cfg(not(test))]`. This PR proposes a new cfg flag, `cfg(doctest)`, specific to this situation, rather than reusing an existing flag. I've isolated it behind a feature gate so that we can contain the effects to nightly only. (A stable workaround that can be used in lieu of `#[cfg(doctest)]` is `#[cfg(rustdoc)] #[doc(hidden)]`, at least once https://github.com/rust-lang/rust/pull/61351 lands.)

r=petrochenkov name the trait in ambiguous-associated-items fully qualified suggestion We have the trait at this point, so we can name it in the error message, rather than using "Trait" as a (potentially confusing) placeholder. Thanks to Yuki "@JohnTitor" Okushi for pointing out where to look (in the same file) for a closely related issue for ambiguous associated types (as opposed to items; that was #59225, except that one won't be quite as easy to resolve, because we actually don't have the trait `DefId` at that point). r? @petrochenkov

2019-07-07Rollup merge of #61990 - llogiq:questionmark-test, r=QuietMisdreavusMazdak Farrokhzad-4/+7
First question mark in doctest We have had `?` for `Result`s in doctests for some time, but so far haven't used them in doctests. With this PR, I want to start the de-`unwrap`ping of doctests – and the discussion on where to do so. There is one downside, which is that the code can no longer be copied into a plain `main()` method, on the other hand, there should be a workable error if one does this.
