2020-04-05Rollup merge of #70558 - RalfJung:vec-extend-aliasing, r=AmanieuDylan DPC-9/+13
Fix some aliasing issues in Vec `Vec::extend` and `Vec::truncate` invalidated references into the vector even without reallocation, because they (implicitly) created a mutable reference covering the *entire* initialized part of the vector. Fixes https://github.com/rust-lang/rust/issues/70301 I verified the fix by adding some new tests here that I ran in Miri.

2020-04-04use ManuallyDrop instead of forget inside collectionsTrevor Spiteri-14/+13
This commit changes some usage of mem::forget into mem::ManuallyDrop in some Vec, VecDeque, BTreeMap and Box methods. Before the commit, the generated IR for some of the methods was longer, and even after optimization, some unwinding artifacts were still present.
2020-04-02Auto merge of #70362 - TimDiekmann:alloc-overhaul, r=Amanieubors-1/+2
Overhaul of the `AllocRef` trait to match allocator-wg's latest consens; Take 2 GitHub won't let me reopen #69889 so I make a new PR. In addition to #69889 this fixes the unsoundness of `RawVec::into_box` when using allocators supporting overallocating. Also it uses `MemoryBlock` in `AllocRef` to unify `_in_place` methods by passing `&mut MemoryBlock`. Additionally, `RawVec` now checks for `size_of::<T>()` again and ignore every ZST. The internal capacity of `RawVec` isn't used by ZSTs anymore, as `into_box` now requires a length to be specified. r? @Amanieu fixes rust-lang/wg-allocators#38 fixes rust-lang/wg-allocators#41 fixes rust-lang/wg-allocators#44 fixes rust-lang/wg-allocators#51

2020-02-26Auto merge of #67290 - jonas-schievink:leak-audit, r=KodrAusbors-14/+35
Audit liballoc for leaks in `Drop` impls when user destructor panics Inspired by https://github.com/rust-lang/rust/pull/67243 and https://github.com/rust-lang/rust/pull/67235, this audits and hopefully fixes the remaining `Drop` impls in liballoc for resource leaks in the presence of panics in destructors called by the affected `Drop` impl. This does not touch `Hash{Map,Set}` since they live in hashbrown. They have similar issues though. r? @KodrAus

2019-12-15Rollup merge of #67300 - aloucks:issue-65970, r=rkruppeMazdak Farrokhzad-1/+16
Restore original implementation of Vec::retain This PR reverts #48065, which aimed to optimize `Vec::retain` by making use of `Vec::drain_filter`. Unfortunately at that time, `drain_filter` was unsound. The soundness hole in `Vec::drain_filter` was fixed in #61224 by guaranteeing that cleanup logic runs via a nested `Drop`, even in the event of a panic. Implementing this nested drop affects codegen (apparently?) and results in slower code. Fixes #65970
