2019-08-02liballoc: Unconfigure tests during normal buildVadim Petrochenkov-430/+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-74/+213
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.

2019-06-14Auto merge of #61421 - vorner:string-in-rc-into-raw-docs, r=RalfJungbors-14/+14
docs: Use String in Rc::into_raw examples 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:-).
