2023-05-06Rollup merge of #110830 - Freaky:freebsd-cpuset, r=thomccYuki Okushi-0/+19
Add FreeBSD cpuset support to `std::thread::available_concurrency` Use libc::cpuset_getaffinity to determine the CPUs available to the current process. The existing sysconf and sysctl paths are left as fallback.

Fix `checked_{add,sub}_duration` incorrectly returning `None` when `other` has more than `i64::MAX` seconds Use `checked_{add,sub}_unsigned` in `checked_{add,sub}_duration` so that the correct result is returned when adding/subtracting durations with more than `i64::MAX` seconds.
2023-05-01Rollup merge of #111057 - xfix:tcpstream-as-raw-fd-inline, r=m-ou-seMatthias Krüger-0/+15
Make sure the implementation of TcpStream::as_raw_fd is fully inlined Currently the following function: ```rust use std::os::fd::{AsRawFd, RawFd}; use std::net::TcpStream; pub fn as_raw_fd(socket: &TcpStream) -> RawFd { socket.as_raw_fd() } ``` Is optimized to the following: ```asm example::as_raw_fd: push rax call qword ptr [rip + <std::net::tcp::TcpStream as std::sys_common::AsInner<std::sys_common::net::TcpStream>>::as_inner@GOTPCREL] mov rdi, rax call qword ptr [rip + std::sys_common::net::TcpStream::socket@GOTPCREL] mov rdi, rax pop rax jmp qword ptr [rip + _ZN73_$LT$std..sys..unix..net..Socket$u20$as$u20$std..os..fd..raw..AsRawFd$GT$9as_raw_fd17h633bcf7e481df8bbE@GOTPCREL] ``` I think it would make more sense to inline trivial functions used within `TcpStream::AsRawFd`.

linkat() not available in the system headers of Solaris 10 I've installed rustup on x86_64-unknown-linux-gnu and would like to use the target sparcv9-sun-solaris. For this, I have built a gcc from the source code for cross-compiling to sparcv9-sun-solaris2.10 with system headers of Solaris 10. With the following hello word example: main.rs: ```rust fn main() { println!("Hello, world!"); } ``` I had a compilation error: ``` $ rustc -v --target sparcv9-sun-solaris -C linker=/opt/cross-solaris/gcc730/bin/sparcv9-sun-solaris2.10-gcc main.rs error: linking with `/opt/cross-solaris/gcc730/bin/sparcv9-sun-solaris2.10-gcc` failed: exit status: 1 | = note: "/opt/cross-solaris/gcc730/bin/sparcv9-sun-solaris2.10-gcc" "-m64" "/tmp/rustcgebYgj/symbols.o" "main.main.89363361-cgu.0.rcgu.o" "main.main.89363361-cgu.1.rcgu.o" "main.main.89363361-cgu.2.rcgu.o" "main.main.89363361-cgu.3.rcgu.o" "main.main.89363361-cgu.4.rcgu.o" "main.main.89363361-cgu.5.rcgu.o" "main.csypsau9u2r8348.rcgu.o" "-Wl,-z,ignore" "-L" "/home/dlaugt/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/sparcv9-sun-solaris/lib" "-Wl,-Bstatic" "/home/dlaugt/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/sparcv9-sun-solaris/lib/libstd-fa47c8247d587714.rlib" "/home/dlaugt/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/sparcv9-sun-solaris/lib/libpanic_unwind-5c87bbe223e6c2a3.rlib" "/home/dlaugt/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/sparcv9-sun-solaris/lib/libobject-d484934062ff9fbb.rlib" "/home/dlaugt/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/sparcv9-sun-solaris/lib/libmemchr-e8dbd5835abcbf43.rlib" "/home/dlaugt/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/sparcv9-sun-solaris/lib/libaddr2line-909ad09329bde2f9.rlib" "/home/dlaugt/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/sparcv9-sun-solaris/lib/libgimli-4d74a3be929697ac.rlib" "/home/dlaugt/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/sparcv9-sun-solaris/lib/librustc_demangle-47cbe1d7f7271ae1.rlib" "/home/dlaugt/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/sparcv9-sun-solaris/lib/libstd_detect-239fd2d25fb32a00.rlib" "/home/dlaugt/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/sparcv9-sun-solaris/lib/libhashbrown-c4a7ce45fb9dec19.rlib" "/home/dlaugt/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/sparcv9-sun-solaris/lib/libminiz_oxide-fa6bc3d9bfb4e402.rlib" "/home/dlaugt/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/sparcv9-sun-solaris/lib/libadler-419f5a82ddd339a3.rlib" "/home/dlaugt/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/sparcv9-sun-solaris/lib/librustc_std_workspace_alloc-7672b378962c11be.rlib" "/home/dlaugt/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/sparcv9-sun-solaris/lib/libunwind-0f9e07f0a032c000.rlib" "/home/dlaugt/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/sparcv9-sun-solaris/lib/libcfg_if-ede7757c356dfb28.rlib" "/home/dlaugt/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/sparcv9-sun-solaris/lib/liblibc-808d56fbc668148a.rlib" "/home/dlaugt/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/sparcv9-sun-solaris/lib/liballoc-784767fe059ad3fe.rlib" "/home/dlaugt/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/sparcv9-sun-solaris/lib/librustc_std_workspace_core-aa31d7ef0556bbe1.rlib" "/home/dlaugt/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/sparcv9-sun-solaris/lib/libcore-81d07df07db18847.rlib" "/home/dlaugt/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/sparcv9-sun-solaris/lib/libcompiler_builtins-313a510e63006db2.rlib" "-Wl,-Bdynamic" "-lsocket" "-lposix4" "-lpthread" "-lresolv" "-lgcc_s" "-lc" "-lm" "-lrt" "-lpthread" "-lsendfile" "-llgrp" "-L" "/home/dlaugt/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/sparcv9-sun-solaris/lib" "-o" "main" "-nodefaultlibs" = note: /opt/cross-solaris/gcc730/lib/gcc/sparcv9-sun-solaris2.10/7.3.0/../../../../sparcv9-sun-solaris2.10/bin/ld: warning: -z ignore ignored. /home/dlaugt/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/sparcv9-sun-solaris/lib/libstd-fa47c8247d587714.rlib(std-fa47c8247d587714.std.5c42d2c1-cgu.0.rcgu.o): In function `std::sys::unix::fs::link::h3683dfbfbb4995cb': /rustc/897e37553bba8b42751c67658967889d11ecd120/library/std/src/sys/unix/fs.rs:1407: undefined reference to `linkat' collect2: error: ld returned 1 exit status = help: some `extern` functions couldn't be found; some native libraries may need to be installed or have their path specified = note: use the `-l` flag to specify native libraries to link = note: use the `cargo:rustc-link-lib` directive to specify the native libraries to link with Cargo (see https://doc.rust-lang.org/cargo/reference/build-scripts.html#cargorustc-link-libkindname) ``` linkat() is not available in the system headers of Solaris 10.

2023-03-30Auto merge of #107221 - kleisauke:getentropy-emscripten, r=ChrisDentonbors-2/+3
Use `getentropy()` instead of `/dev/urandom` on Emscripten `/dev/urandom` is usually available on Emscripten, except when using the special `NODERAWFS` filesystem backend, which replaces all normal filesystem access with direct Node.js operations. Since this filesystem backend directly access the filesystem on the OS, it is not recommended to depend on `/dev/urandom`, especially when trying to run the Wasm binary on OSes that are not Unix-based. This can be considered a non-functional change, since Emscripten implements `/dev/urandom` in the same way as `getentropy()` when not linking with `-sNODERAWFS`.

2023-03-06Implement read_buf for a few more typesTomasz Miąsko-8/+41
Implement read_buf for TcpStream, Stdin, StdinLock, ChildStdout, ChildStderr (and internally for AnonPipe, Handle, Socket), so that it skips buffer initialization. The other provided methods like read_to_string and read_to_end are implemented in terms of read_buf and so benefit from the optimization as well. This commit also implements read_vectored and is_read_vectored where applicable.

Add support for QNX Neutrino to standard library This change: - adds standard library support for QNX Neutrino (7.1). - upgrades `libc` to version `0.2.139` which supports QNX Neutrino `@gh-tr` ⚠️ Backtraces on QNX require https://github.com/rust-lang/backtrace-rs/pull/507 which is not yet merged! (But everything else works without these changes) ⚠️ Tested mainly with a x86_64 virtual machine (see qnx-nto.md) and partially with an aarch64 hardware (some tests fail due to constrained resources).

2023-02-11Rollup merge of #106001 - sdroege:glibc-skip-over-null-argv, r=ChrisDentonDylan DPC-6/+22
Stop at the first `NULL` argument when iterating `argv` Some C commandline parsers (e.g. GLib and Qt) are replacing already handled arguments in `argv` with `NULL` and move them to the end. That means that `argc` might be bigger than the actual number of non-`NULL` pointers in `argv` at this point. To handle this we simply stop iterating at the first `NULL` argument. `argv` is also guaranteed to be `NULL`-terminated so any non-`NULL` arguments after the first `NULL` can safely be ignored. Fixes https://github.com/rust-lang/rust/issues/105999
2023-01-26Rollup merge of #106779 - RReverser:patch-2, r=Mark-SimulacrumMatthias Krüger-8/+3
Avoid __cxa_thread_atexit_impl on Emscripten - Fixes https://github.com/rust-lang/rust/issues/91628. - Fixes https://github.com/emscripten-core/emscripten/issues/15722. See discussion in both issues. The TL;DR is that weak linkage causes LLVM to produce broken Wasm, presumably due to pointer mismatch. The code is casting a void pointer to a function pointer with specific signature, but Wasm is very strict about function pointer compatibility, so the resulting code is invalid. Ideally LLVM should catch this earlier in the process rather than emit invalid Wasm, but it currently doesn't and this is an easy and valid fix, given that Emcripten doesn't have `__cxa_thread_atexit_impl` these days anyway. Unfortunately, I can't add a regression test as even after looking into this issue for a long time, I couldn't reproduce it with any minimal Rust example, only with extracted LLVM IR or on a large project involving Rust + C++.

2023-01-14Rollup merge of #106661 - mjguzik:linux_statx, r=Mark-SimulacrumMatthias Krüger-27/+41
Stop probing for statx unless necessary As is the current toy program: fn main() -> std::io::Result<()> { use std::fs; let metadata = fs::metadata("foo.txt")?; assert!(!metadata.is_dir()); Ok(()) } ... observed under strace will issue: [snip] statx(0, NULL, AT_STATX_SYNC_AS_STAT, STATX_ALL, NULL) = -1 EFAULT (Bad address) statx(AT_FDCWD, "foo.txt", AT_STATX_SYNC_AS_STAT, STATX_ALL, {stx_mask=STATX_ALL|STATX_MNT_ID, stx_attributes=0, stx_mode=S_IFREG|0644, stx_size=0, ...}) = 0 While statx is not necessarily always present, checking for it can be delayed to the first error condition. Said condition may very well never happen, in which case the check got avoided altogether. Note this is still suboptimal as there still will be programs issuing it, but bulk of the problem is removed. Tested by forbidding the syscall for the binary and observing it correctly falls back to newfstatat. While here tidy up the commentary, in particular by denoting some problems with the current approach.
