2025-02-09Auto merge of #136751 - bjorn3:update_rustfmt, r=Mark-Simulacrumbors-3/+4
Update bootstrap compiler and rustfmt The rustfmt version we previously used formats things differently from what the latest nightly rustfmt does. This causes issues for subtrees that get formatted both in-tree and in their own repo. Updating the rustfmt used in-tree solves those issues. Also bumped the bootstrap compiler as the stage0 update command always updates both at the same time.

2025-02-08Rollup merge of #135696 - joboet:move_pal_io, r=NoratriebMatthias Krüger-1/+1
std: move `io` module out of `pal`, get rid of `sys_common::io` Part of #117276. This does two related things: 1. It moves the platform-specific definitions for `IoSlice`, `IoSliceMut` and `is_terminal` out of `pal` and into `sys` and unifies some of them. 2. It gets rid of `sys_common::io`, moving the non-platform-specific test helpers into `std::test_helpers` and the buffer size definition to the new `sys::io` module.

2025-01-25Rollup merge of #135948 - bjorn3:update_emscripten_std_tests, r=Mark-SimulacrumJacob Pratt-2/+1
Update emscripten std tests This disables a bunch of emscripten tests that test things emscripten doesn't support and re-enables a whole bunch of tests which now work just fine on emscripten. Tested with `EMCC_CFLAGS="-s MAXIMUM_MEMORY=2GB" ./x.py test library/ --target wasm32-unknown-emscripten`.
2025-01-25Improve and expand documentation of pipesJosh Triplett-8/+14
- Simplify some of the language - Minor grammar fixes - Don't imply that pipes *only* work across multiple processes; instead, *suggest* that they're typically used across two or more separate processes. - Specify that portable applications cannot use multiple readers or multiple writers for messages larger than a byte, due to potential interleaving. - Remove no-longer-referenced footnote URLs.
2025-01-24Remove a bunch of emscripten test ignoresbjorn3-2/+0
They are either outdated as emscripten now supports i128 or they are subsumed by #[cfg_attr(not(panic = "unwind"), ignore]
2025-01-24Fix testing of the standard library with Emscriptenbjorn3-0/+1
This does need EMCC_CFLAGS="-s MAXIMUM_MEMORY=2GB" avoid several OOMs.

2024-12-06Rollup merge of #130209 - GrigorenkoPV:CrossesDevices, r=dtolnayMatthias Krüger-1/+1
Stabilize `std::io::ErrorKind::CrossesDevices` FCP in #130191 cc #86442 See #130191 for more info and a recap of what has happened up until now. TLDR: This had been FCP'd in December 2022 with some other `ErrorKind`s, but the stabilization got postponed due to some concerns voiced about several of the variants. However, the only concern ever voiced for this variant in particular was a wish to rename this to `NotSameDevice` analogous to Windows's `ERROR_NOT_SAME_DEVICE` (as opposed to Unix's `EXDEV`). This suggestion did not receive any support. So let's try to FCP this as is. r? libs-api

Mark `get_mut` and `set_position` in `std::io::Cursor` as const. Relevant tracking issue: #130801 The methods `get_mut` and `set_position` can trivially be marked as const due to #57349 being stabilised.

2024-09-30Rollup merge of #130914 - compiler-errors:insignificant-dtor, r=AmanieuTrevor Gross-0/+1
Mark some more types as having insignificant dtor These were caught by https://github.com/rust-lang/rust/pull/129864#issuecomment-2376658407, which is implementing a lint for some changes in drop order for temporaries in tail expressions. Specifically, the destructors of `CString` and the bitpacked repr for `std::io::Error` are insignificant insofar as they don't have side-effects on things like locking or synchronization; they just free memory. See some discussion on #89144 for what makes a drop impl "significant"

Add `File` constructors that return files wrapped with a buffer In addition to the light convenience, these are intended to raise visibility that buffering is something you should consider when opening a file, since unbuffered I/O is a common performance footgun to Rust newcomers.
