std: merge definitions of `StdioPipes`

2025-09-21T17:45:46+00:00

All platforms define this structure the same way, so we can just put it in the `process` module directly.

Rollup merge of #146800 - thaliaarchi:fix-move-pal-thread, r=joboet

2025-09-20T15:55:05+00:00

Fix unsupported `std::sys::thread` after move Fixes building std for any platform with an unsupported thread abstraction. This includes {aarch64,armv7,x86_64}-unknown-trusty and riscv32im-risc0-zkvm-elf, which explicitly include the unsupported module, and platforms with no PAL. Bug fix for rust-lang/rust#145177 (std: move thread into sys). Also fix the `std` build for xtensa, which I incidentally found while looking for an unsupported platform. r? ``@joboet``

library: Migrate from `cfg_if` to `cfg_select`

2025-08-16T12:28:31+00:00

Migrate the standard library from using the external `cfg_if` crate to using the now-built-in `cfg_select` macro. This does not yet eliminate the dependency from `library/std/Cargo.toml`, because while the standard library itself no longer uses `cfg_if`, it also incorporates the `backtrace` crate, which does. Migration assisted by the following vim command (after selecting the full `cfg_if!` invocation): ``` '<,'>s/\(cfg_if::\)\?cfg_if/cfg_select/ | '<,'>s/^\( *\)} else {/\1}\r\1_ => {/c | '<,'>s/^\( *\)} else if #\[cfg(\(.*\))\] /\1}\r\1\2 => /e | '<,'>s/if #\[cfg(\(.*\))\] {/\1 => {/e ``` This is imperfect, but substantially accelerated the process. This prompts for confirmation on the `} else {` since that can also appear inside one of the arms. This also requires manual intervention to handle any multi-line conditions.

Replace unsafe function with safe alternative

2025-08-09T07:05:12+00:00

The `security_attributes` function is marked as safe despite taking a raw pointer which will later be used. Fortunately this function is only used internally and only in one place that has been basically the same for a decade now. However, we only ever set one bool so it's easy enough to replace with something that's actually safe.

Rollup merge of #142391 - LevitatingBusinessMan:setsid, r=workingjubilee

2025-07-11T05:35:17+00:00

rust: library: Add `setsid` method to `CommandExt` trait Add a setsid method to the CommandExt trait so that callers can create a process in a new session and process group whilst still using the POSIX spawn fast path. Tracking issue: rust-lang/rust#105376 ACP: https://github.com/rust-lang/libs-team/issues/184 This PR was previously submitted by ``@HarveyHunt`` (whom I marked as Co-Author in the commit message) in rust-lang/rust#105377. However that PR went stale. I applied the [suggestion](https://github.com/rust-lang/rust/pull/105377/files/231d19fcbfe155b2e85116865adae4253380ff1f#r1893457943) to change the function signature to `fn setsid(&mut self, setsid: bool) -> &mut Command`.
