2019-08-02liballoc: Unconfigure tests during normal buildVadim Petrochenkov-483/+3
Remove additional libcore-like restrictions from liballoc, turns out the testing works ok if the tests are a part of liballoc itself.

2019-07-13Auto merge of #61953 - Centril:shared-from-iter, r=RalfJungbors-66/+198
Add `impl<T> FromIterator<T> for Arc/Rc<[T]>` Add implementations of `FromIterator<T> for Arc/Rc<[T]>` with symmetrical logic. This also takes advantage of specialization in the case of iterators with known length (`TrustedLen`) to elide the final allocation/copying from a `Vec<T>` into `Rc<[T]>` because we can allocate the space for the `Rc<[T]>` directly when the size is known. This is the primary motivation and why this is to be preferred over `iter.collect::<Vec<_>>().into(): Rc<[T]>`. Moreover, this PR does some refactoring in some places. r? @RalfJung for the code cc @alexcrichton from T-libs
2019-07-06Rollup merge of #61862 - vorner:weak-into-raw-methods, r=sfacklerMazdak Farrokhzad-15/+15
Make the Weak::{into,as}_raw methods Because Weak doesn't Deref, so there's no reason for them to be only associated methods. As kindly pointed out here https://github.com/rust-lang/rust/pull/60766#issuecomment-501706422 by @chpio.

2019-06-13docs: Use String in Rc::into_raw examplesMichal 'vorner' Vaner-14/+14
It is unclear if accessing an integer after `drop_in_place` has been called on it is undefined behaviour or not, as demonstrated by the discussion in https://github.com/rust-lang/rust/pull/60766#pullrequestreview-243414222. Avoid these uncertainties by using String which frees memory in its `drop_in_place` to make sure this is undefined behaviour. The message in the docs should be to watch out and not access the data after that, not discussing when one maybe could get away with it O:-).
2019-05-26sync::Weak::{as,from,into}_rawMichal 'vorner' Vaner-6/+158
Methods on the Weak to access it as raw pointer to the data.

2019-01-31Auto merge of #56696 - jonas-schievink:weak-counts, r=alexcrichtonbors-1/+83
Implement Weak::{strong_count, weak_count} The counters are also useful on `Weak`, not just on strong references (`Rc` or `Arc`). In situations where there are still strong references around, you can also get these counts by temporarily upgrading and adjusting the values accordingly. Using the methods introduced here is simpler to do, less error-prone (since you can't forget to adjust the counts), can also be used when no strong references are around anymore, and might be more efficient due to not having to temporarily create an `Rc`. This is mainly useful in assertions or tests of complex data structures. Data structures might have internal invariants that make them the sole owner of a `Weak` pointer, and an assertion on the weak count could be used to ensure that this indeed happens as expected. Due to the presence of `Weak::upgrade`, the `strong_count` becomes less useful, but it still seems worthwhile to mirror the API of `Rc`.

2018-12-23Rollup merge of #56939 - cramertj:pin-stabilization, r=alexcrichtonMazdak Farrokhzad-3/+5
Pin stabilization This implements the changes suggested in https://github.com/rust-lang/rust/issues/55766#issue-378417538 and stabilizes the `pin` feature. @alexcrichton also listed several "blockers" in that issue, but then in [this comment](https://github.com/rust-lang/rust/issues/55766#issuecomment-445074980) mentioned that they're more "TODO items": > In that vein I think it's fine for a stabilization PR to be posted at any time now with FCP lapsed for a week or so now. The final points about self/pin/pinned can be briefly discussed there (if even necessary, they could be left as the proposal above). Let's settle these last bits here and get this thing stabilized! :) r? @alexcrichton cc @withoutboats

r=QuietMisdreavus deny intra-doc link resolution failures in libstd Fixes #56693. Until we land a fix for the underlying issue (#56922), we can at least fix the failures in libstd so they don't propagate to downstream crates.
