2020-06-15Rollup merge of #73104 - poliorcetics:explicit-mutex-drop-example, r=dtolnayRalf Jung-0/+54
Example about explicit mutex dropping Fixes #67457. Following the remarks made in #73074, I added an example on the main `Mutex` type, with a situation where there is mutable data and a computation result. In my testing it is effectively needed to explicitly drop the lock, else it deadlocks. r? @dtolnay because you were the one to review the previous PR.

2020-06-12Revert heterogeneous SocketAddr PartialEq implsDavid Tolnay-40/+0
These lead to inference regressions (mostly in tests) in code that looks like: let socket = std::net::SocketAddrV4::new(std::net::Ipv4Addr::new(127, 0, 0, 1), 8080); assert_eq!(socket, "127.0.0.1:8080".parse().unwrap()); That compiles as of stable 1.44.0 but fails in beta with: error[E0284]: type annotations needed --> src/main.rs:3:41 | 3 | assert_eq!(socket, "127.0.0.1:8080".parse().unwrap()); | ^^^^^ cannot infer type for type parameter `F` declared on the associated function `parse` | = note: cannot satisfy `<_ as std::str::FromStr>::Err == _` help: consider specifying the type argument in the method call | 3 | assert_eq!(socket, "127.0.0.1:8080".parse::<F>().unwrap()); |

2020-06-08Auto merge of #72655 - jethrogb:sgx-lvi-hardening, r=petrochenkovbors-6/+16
Enable LVI hardening for x86_64-fortanix-unknown-sgx This implements mitigations for the Load Value Injection vulnerability (CVE-2020-0551) for the `x86_64-fortanix-unknown-sgx` target by enabling new LLVM passes. More information about LVI and mitigations may be found at https://software.intel.com/security-software-guidance/insights/deep-dive-load-value-injection. This PR unconditionally enables the mitigations for `x86_64-fortanix-unknown-sgx` since there is no available hardware that doesn't require the mitigations. This may be reconsidered in the future. * [x] This depends on https://github.com/rust-lang/compiler-builtins/pull/359/

2020-06-08Rollup merge of #72963 - poliorcetics:cstring-from-raw, r=dtolnayRalf Jung-0/+11
Cstring `from_raw` and `into_raw` safety precisions Fixes #48525. Fixes #68456. This issue had two points: - The one about `from_raw` has been addressed (I hope). - The other one, about `into_raw`, has only been partially fixed. About `into_raw`: the idea was to: > steer users away from using the pattern of CString::{into_raw,from_raw} when interfacing with C APIs that may change the effective length of the string by writing interior NULs or erasing the final NUL I tried making a `Vec<c_char>` like suggested but my current solution feels very unsafe and *hacky* to me (most notably the type cast), I included it here to make it available for discussion: ```rust fn main() { use std::os::raw::c_char; let v = String::from("abc") .bytes() // From u8 to i8, // I feel like it will be a problem for values of u8 > 255 .map(|c| c as c_char) .collect::<Vec<_>>(); dbg!(v); } ```
2020-06-08Rollup merge of #72761 - poliorcetics:use-keyword-doc, r=Dylan-DPCRalf Jung-2/+54
Added the documentation for the 'use' keyword This is a partial fix of #34601. I heavily inspired myself from the Reference on the `use` keyword. I checked the links when compiling the documentation, they should be ok. I also added an example for the wildcard `*` in the case of types, because it's behaviour is not *import everything* like one might think at first.
