2020-08-18Rollup merge of #75464 - poliorcetics:intra-links-panic-and-ascii, r=jyn514Yuki Okushi-30/+10
Move to intra doc links for ascii.rs and panic.rs Helps with #75080. @rustbot modify labels: T-doc, A-intra-doc-links, T-rustdoc I also updated the doc to fix the wording in `AsciiExt` since it is now deprecated. The two file are small changes so I bundled them together. Some links could not be changed to make them work, I believe those are known issues with primitive types.

2020-08-15Auto merge of #74576 - myfreeweb:freebsd-sanitizers, r=oli-obkbors-1/+13
Add sanitizer support on FreeBSD Restarting #47337. Everything is better now, no more weird llvm problems, well not everything: Unfortunately, the sanitizers don't have proper support for versioned symbols (https://github.com/google/sanitizers/issues/628), so `libc`'s usage of `stat@FBSD_1.0` and so on explodes, e.g. in calling `std::fs::metadata`. Building std (now easy thanks to cargo `-Zbuild-std`) and libc with `freebsd12/13` config via the `LIBC_CI=1` env variable is a good workaround… ``` LIBC_CI=1 RUSTFLAGS="-Z sanitizer=address" cargo +san-test -Zbuild-std run --target x86_64-unknown-freebsd --verbose ``` …*except* std won't build because there's no `st_lspare` in the ino64 version of the struct, so an std patch is required: ```diff --- i/src/libstd/os/freebsd/fs.rs +++ w/src/libstd/os/freebsd/fs.rs @@ -66,8 +66,6 @@ pub trait MetadataExt { fn st_flags(&self) -> u32; #[stable(feature = "metadata_ext2", since = "1.8.0")] fn st_gen(&self) -> u32; - #[stable(feature = "metadata_ext2", since = "1.8.0")] - fn st_lspare(&self) -> u32; } #[stable(feature = "metadata_ext", since = "1.1.0")] @@ -136,7 +134,4 @@ impl MetadataExt for Metadata { fn st_flags(&self) -> u32 { self.as_inner().as_inner().st_flags as u32 } - fn st_lspare(&self) -> u32 { - self.as_inner().as_inner().st_lspare as u32 - } } ``` I guess std could like.. detect that `libc` isn't built for the old ABI, and replace the implementation of `st_lspare` with a panic?

2020-08-14Rollup merge of #75545 - eddyb:instant-sub-branchless, r=sfacklerTyler Mandry-8/+20
std/sys/unix/time: make it easier for LLVM to optimize `Instant` subtraction. This PR is the minimal change necessary to get LLVM to optimize `if self.t.tv_nsec >= other.t.tv_nsec` to branchless instructions (at least on x86_64), inspired by @m-ou-se's own attempts at optimizing `Instant` subtraction. I stumbled over this by looking at the total number of instructions executed by `rustc -Z self-profile`, and found that after disabling ASLR, the largest source of non-determinism remaining was from this `if` taking one branch or the other, depending on the values involved. The reason this code is even called so many times to make a difference, is that `measureme` (the `-Z self-profile` implementation) currently uses `Instant::elapsed` for its event timestamps (of which there can be millions). I doubt it's critical to land this, although perhaps it could slightly improve some forms of benchmarking.

2020-08-14Rollup merge of #74409 - ↵Tyler Mandry-2/+16
LukasKalbertodt:improve-debug-impl-of-socketaddr-ipaddr, r=Amanieu Change Debug impl of SocketAddr and IpAddr to match their Display output This has already been done for `SocketAddrV4`, `SocketAddrV6`, `IpAddrV4` and `IpAddrV6`. I don't see a point to keep the rather bad to read derived impl, especially so when pretty printing: V4( 127.0.0.1 ) From the `Display`, one can easily and unambiguously see if it's V4 or V6. Two examples: ``` 127.0.0.1:443 [2001:db8:85a3::8a2e:370:7334]:443 ``` Luckily the docs explicitly state that `Debug` output is not stable and that it may be changed at any time. Using `Display` as `Debug` is very convenient for configuration structs (e.g. for webservers) that often just have a `derive(Debug)` and are printed that way to the one starting the server.

Improve documentation on process::Child.std* fields As a relative beginner, it took a while for me to figure out I could just steal the references to avoid partially moving the child and thus retain ability to call functions on it (and store it in structs etc).

2020-08-13Rollup merge of #75189 - kawamuray:bugfix-wasi-append, r=KodrAusYuki Okushi-3/+5
Fix wasi::fs::OpenOptions to imply write when append is on This PR fixes a bug in `OpenOptions` of `wasi` platform that it currently doesn't imply write mode when only `append` is enabled. As explained in the [doc of OpenOptions#append](https://doc.rust-lang.org/std/fs/struct.OpenOptions.html#method.append), calling `.append(true)` should imply `.write(true)` as well. ## Reproduce Given below simple Rust program: ```rust use std::fs::OpenOptions; use std::io::Write; fn main() { let mut file = OpenOptions::new() .write(true) .create(true) .open("foo.txt") .unwrap(); writeln!(file, "abc").unwrap(); } ``` it can successfully compiled into wasm and execute by `wasmtime` runtime: ```sh $ rustc --target wasm32-wasi write.rs $ ~/wasmtime/target/debug/wasmtime run --dir=. write.wasm $ cat foo.txt abc ``` However when I change `.write(true)` to `.append(true)`, it fails to execute by the error "Capabilities insufficient": ```sh $ ~/wasmtime/target/debug/wasmtime run --dir=. append.wasm thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Os { code: 76, kind: Other, message: "Capabilities insufficient" }', append.rs:10:5 note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace Error: failed to run main module `append.wasm` ... ``` This is because of lacking "rights" on the opened file: ```sh $ RUST_LOG=trace ~/wasmtime/target/debug/wasmtime run --dir=. append.wasm 2>&1 | grep validate_rights TRACE wasi_common::entry > | validate_rights failed: required rights = HandleRights { base: fd_write (0x40), inheriting: empty (0x0) }; actual rights = HandleRights { base: fd_seek|fd_fdstat_set_flags|fd_sync|fd_tell|fd_advise|fd_filestat_set_times|poll_fd_readwrite (0x88000bc), inheriting: empty (0x0) } ```
