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

impl TrustedLen for vec::Drain The iterator methods just forward to `slice::Iter`, which is `TrustedLen`. This can probably be applied to other `Drain` structs as well.

The previous ordering of the sentences kept switching between the return value and the value of `self` after execution, making it hard to follow. Additionally, as rendered in the browser, the period in "`Self`. `self`" was difficult to make out as being a sentence separator and not one code block.
2019-11-15Auto merge of #64432 - gnzlbg:simplify_truncate, r=alexcrichtonbors-22/+12
Make the semantics of Vec::truncate(N) consistent with slices. This commit simplifies the implementation of `Vec::truncate(N)` and makes its semantics identical to dropping the `[vec.len() - N..]` sub-slice tail of the vector, which is the same behavior as dropping a vector containing the same sub-slice. This changes two unspecified aspects of `Vec::truncate` behavior: * the drop order, from back-to-front to front-to-back, * the behavior of `Vec::truncate` on panics: if dropping one element of the tail panics, currently, `Vec::truncate` panics, but with this PR all other elements are still dropped, and if dropping a second element of the tail panics, with this PR, the program aborts. Programs can trivially observe both changes. For example ([playground](https://play.rust-lang.org/?version=stable&mode=debug&edition=2018&gist=7bef575b83b06e82b3e3529e4edbcac7)): ```rust fn main() { struct Bomb(usize); impl Drop for Bomb { fn drop(&mut self) { panic!(format!("{}", self.0)); } } let mut v = vec![Bomb(0), Bomb(1)]; std::panic::catch_unwind(std::panic::AssertUnwindSafe(|| { v.truncate(0); })); assert_eq!(v.len(), 1); std::mem::forget(v); } ``` panics printing `1` today and succeeds. With this change, it panics printing `0` first (due to the drop order change), and then aborts with a double-panic printing `1`, just like dropping the `[Bomb(0), Bomb(1)]` slice does, or dropping `vec![Bomb(0), Bomb(1)]` does. This needs to go through a crater run. r? @SimonSapin
