2019-09-25Fix ExitStatus on FuchsiaTyler Mandry-75/+93
Fuchsia exit codes don't follow the convention of libc::WEXITSTATUS et al, and they are 64 bits instead of 32 bits. This gives Fuchsia its own representation of ExitStatus. Additionally, the zircon syscall structs were out of date, causing us to see bogus return codes.

2019-09-25Rollup merge of #64481 - tomtau:fix/tls-error-message, r=KodrAusMazdak Farrokhzad-2/+2
A more explanatory thread local storage panic message Outside rust-std internals, TLS is usually understood as Transport Layer Security, so the existing message could be a bit puzzling when one has TLS sessions in `thread_local!`.

2019-09-23Rollup merge of #64294 - wchargin:wchargin-stdio-piped-docs, r=Dylan-DPCMazdak Farrokhzad-1/+1
Fix `Stdio::piped` example code and lint Summary: Invoking `rev` does not add a trailing newline when none is present in the input (at least on my Debian). Nearby examples use `echo` rather than `rev`, which probably explains the source of the discrepancy. Also, a `mut` qualifier is unused. Test Plan: Copy the code block into <https://play.rust-lang.org> with a `fn main` wrapper, and run it. Note that it compiles and runs cleanly; prior to this commit, it would emit an `unused_mut` warning and then panic. wchargin-branch: stdio-piped-docs

Added table containing the system calls used by Instant and SystemTime. # Description See #32626 for a discussion on documenting system calls used by Instant and SystemTime. ## Changes - Added a table containing the system calls used by each platform. EDIT: If I can format this table better (due to the large links) please let me know. I'd also be happy to learn a quick command to generate the docs on my host machine! Currently I am using: `python x.py doc --stage 0 src/libstd` but that gives me some `unrecognized intrinsic` errors. Advice is always welcome :) closes #32626

2019-09-11Auto merge of #64154 - alexcrichton:std-backtrace, r=sfacklerbors-54/+433
std: Add a `backtrace` module This commit adds a `backtrace` module to the standard library, as designed in [RFC 2504]. The `Backtrace` type is intentionally very conservative, effectively only allowing capturing it and printing it. Additionally this commit also adds a `backtrace` method to the `Error` trait which defaults to returning `None`, as specified in [RFC 2504]. More information about the design here can be found in [RFC 2504] and in the [tracking issue]. Implementation-wise this is all based on the `backtrace` crate and very closely mirrors the `backtrace::Backtrace` type on crates.io. Otherwise it's pretty standard in how it handles everything internally. [RFC 2504]: https://github.com/rust-lang/rfcs/blob/master/text/2504-fix-error.md [tracking issue]: https://github.com/rust-lang/rust/issues/53487 cc #53487

2019-09-09Auto merge of #63118 - Centril:stabilize-bind-by-move, r=matthewjasperbors-1/+1
Stabilize `bind_by_move_pattern_guards` in Rust 1.39.0 Closes https://github.com/rust-lang/rust/issues/15287. After stabilizing `#![feature(bind_by_move_pattern_guards)]`, you can now use bind-by-move bindings in patterns and take references to those bindings in `if` guards of `match` expressions. For example, the following now becomes legal: ```rust fn main() { let array: Box<[u8; 4]> = Box::new([1, 2, 3, 4]); match array { nums // ---- `nums` is bound by move. if nums.iter().sum::<u8>() == 10 // ^------ `.iter()` implicitly takes a reference to `nums`. => { drop(nums); // --------- Legal as `nums` was bound by move and so we have ownership. } _ => unreachable!(), } } ``` r? @matthewjasper
