2024-12-10Rollup merge of #133472 - rust-wasi-web:master, r=joboetLeón Orell Valerian Liehr-1/+24
Run TLS destructors for wasm32-wasip1-threads The target wasm32-wasip1-threads has support for pthreads and allows registration of TLS destructors. For spawned threads, this registers Rust TLS destructors by creating a pthreads key with an attached destructor function. For the main thread, this registers an `atexit` handler to run the TLS destructors. try-job: test-various

2024-12-10Rollup merge of #133184 - osiewicz:wasm-fix-infinite-loop-in-remove-dir-all, ↵León Orell Valerian Liehr-70/+105
r=Noratrieb wasi/fs: Improve stopping condition for <ReadDir as Iterator>::next When upgrading [Zed](https://github.com/zed-industries/zed/pull/19349) to Rust 1.82 I've encountered a test failure in our test suite. Specifically, one of our extension tests started hanging. I've tracked it down to a call to std::fs::remove_dir_all not returning when an extension is compiled with Rust 1.82 Our extension system uses WASM components, thus I've looked at the diff between 1.81 and 1.82 with respect to WASI and found 736f773844e7ebf05ccb827c17b7ad9eb28aa295 As it turned out, calling remove_dir_all from extension returned io::ErrorKind::NotFound in 1.81; the underlying issue is that the ReadDir iterator never actually terminates iteration, however since it loops around, with 1.81 we'd come across an entry second time and fail to remove it, since it would've been removed previously. With 1.82 and 736f773844e7ebf05ccb827c17b7ad9eb28aa295 it is no longer the case, thus we're seeing the hang. The tests do pass when everything but the extensions is compiled with 1.82. This commit makes ReadDir::next adhere to readdir contract, namely it will no longer call readdir once the returned # of bytes is smaller than the size of a passed-in buffer. Previously we'd only terminate the loop if readdir returned 0.

2024-12-06Auto merge of #118159 - EliasHolzmann:formatting_options, r=m-ou-sebors-85/+366
Implementation of `fmt::FormattingOptions` Tracking issue: #118117 Public API: ```rust #[derive(Copy, Clone, Debug, PartialEq, Eq)] pub struct FormattingOptions { … } #[derive(Copy, Clone, Debug, PartialEq, Eq)] pub enum Sign { Plus, Minus } #[derive(Copy, Clone, Debug, PartialEq, Eq)] pub enum DebugAsHex { Lower, Upper } impl FormattingOptions { pub fn new() -> Self; pub fn sign(&mut self, sign: Option<Sign>) -> &mut Self; pub fn sign_aware_zero_pad(&mut self, sign_aware_zero_pad: bool) -> &mut Self; pub fn alternate(&mut self, alternate: bool) -> &mut Self; pub fn fill(&mut self, fill: char) -> &mut Self; pub fn align(&mut self, alignment: Option<Alignment>) -> &mut Self; pub fn width(&mut self, width: Option<usize>) -> &mut Self; pub fn precision(&mut self, precision: Option<usize>) -> &mut Self; pub fn debug_as_hex(&mut self, debug_as_hex: Option<DebugAsHex>) -> &mut Self; pub fn get_sign(&self) -> Option<Sign>; pub fn get_sign_aware_zero_pad(&self) -> bool; pub fn get_alternate(&self) -> bool; pub fn get_fill(&self) -> char; pub fn get_align(&self) -> Option<Alignment>; pub fn get_width(&self) -> Option<usize>; pub fn get_precision(&self) -> Option<usize>; pub fn get_debug_as_hex(&self) -> Option<DebugAsHex>; pub fn create_formatter<'a>(self, write: &'a mut (dyn Write + 'a)) -> Formatter<'a>; } impl<'a> Formatter<'a> { pub fn new(write: &'a mut (dyn Write + 'a), options: FormattingOptions) -> Self; pub fn with_options<'b>(&'b mut self, options: FormattingOptions) -> Formatter<'b>; pub fn sign(&self) -> Option<Sign>; pub fn options(&self) -> FormattingOptions; } ``` Relevant changes from the public API in the tracking issue (I'm leaving out some stuff I consider obvious mistakes, like missing `#[derive(..)]`s and `pub` specifiers): - `enum DebugAsHex`/`FormattingOptions::debug_as_hex`/`FormattingOptions::get_debug_as_hex`: To support `{:x?}` as well as `{:X?}`. I had completely missed these options in the ACP. I'm open for any and all bikeshedding, not married to the name. - `fill`/`get_fill` now takes/returns `char` instead of `Option<char>`. This simply mirrors what `Formatter::fill` returns (with default being `' '`). - Changed `zero_pad`/`get_zero_pad` to `sign_aware_zero_pad`/`get_sign_aware_zero_pad`. This also mirrors `Formatter::sign_aware_zero_pad`. While I'm not a fan of this quite verbose name, I do believe that having the interface of `Formatter` and `FormattingOptions` be compatible is more important. - For the same reason, renamed `alignment`/`get_alignment` to `aling`/`get_align`. - Deviating from my initial idea, `Formatter::with_options` returns a `Formatter` which has the lifetime of the `self` reference as its generic lifetime parameter (in the original API spec, the generic lifetime of the returned `Formatter` was the generic lifetime used by `self` instead). Otherwise, one could construct two `Formatter`s that both mutably borrow the same underlying buffer, which would be unsound. This solution still has performance benefits over simply using `Formatter::new`, so I believe it is worthwhile to keep this method.

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

2024-12-05Rollup merge of #133821 - Kobzol:replace-black-with-ruff, r=onur-ozkanGuillaume Gomez-19/+34
Replace black with ruff in `tidy` `ruff` can both lint and format Python code (in fact, it should be a mostly drop-in replacement for `black` in terms of formatting), so it's not needed to use `black` anymore. This PR removes `black` and replaces it with `ruff`, to get rid of one Python dependency, and also to make Python formatting faster (although that's a small thing). If we decide to merge this, we'll need to "reformat the world" - `ruff` is not perfectly compatible with `black`, and it also looks like `black` was actually ignoring some files before. I tried it locally (`./x test tidy --extra-checks=py:fmt --bless`) and it also reformatted some code in subtrees (e.g. `clippy` or `rustc_codegen_gcc`) - I'm not sure how to handle that.

Likewise for `get_alignment`. This is how the method is named on `Formatter`, I want to keep it consistent.
2024-12-05Formatter::with_options: Use different lifetimesElias Holzmann-1/+1
Formatter::with_options takes self as a mutable reference (`&'a mut Formatter<'b>`). `'a` and `'b` need to be different lifetimes. Just taking `&'a mut Formatter<'a>` and trusting in Rust being able to implicitely convert from `&'a mut Formatter<'b>` if necessary (after all, `'a` must be smaller than `'b` anyway) fails because `'b` is behind a *mutable* reference. For background on on this behavior, see https://doc.rust-lang.org/nomicon/subtyping.html#variance.

2024-12-05Formatter: Access members via getter methods wherever possibleElias Holzmann-16/+16
The idea behind this is to make implementing `fmt::FormattingOptions` (as well as any future changes to `std::Formatter`) easier. In theory, this might have a negative performance impact because of the additional function calls. However, I strongly believe that those will be inlined anyway, thereby producing assembly code that has comparable performance.

Take this comment for example: ``` // Any frames between `__rust_begin_short_backtrace` and `__rust_end_short_backtrace` // are omitted from the backtrace in short mode, `__rust_end_short_backtrace` will be // called before the panic hook, so we won't ignore any frames if there is no // invoke of `__rust_begin_short_backtrace`. ``` this is just wrong. here is an example (full) backtrace: <details> ``` Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.01s Running `/home/jyn/.local/lib/cargo/target/debug/example` called `Option::unwrap()` on a `None` value stack backtrace: 0: 0x56499698c595 - std::backtrace_rs::backtrace::libunwind::trace::h5ef2cc16e9a7415a 1: 0x56499698c595 - std::backtrace_rs::backtrace::trace_unsynchronized::h9b5e016e9075f714 2: 0x56499698c595 - std::sys_common::backtrace::_print_fmt::h2f62c7f9ff224e93 3: 0x56499698c595 - <std::sys_common::backtrace::_print::DisplayBacktrace as core::fmt::Display>::fmt::hbe51682735731910 4: 0x5649969aa26b - core::fmt::rt::Argument::fmt::h1994ab2b310d665e 5: 0x5649969aa26b - core::fmt::write::hade58a36d63468d7 6: 0x56499698a43f - std::io::Write::write_fmt::h16145587d801a9ab 7: 0x56499698c36e - std::sys_common::backtrace::_print::ha8082e56201dadb4 8: 0x56499698c36e - std::sys_common::backtrace::print::he30f96b4e7f6cbfd 9: 0x56499698d709 - std::panicking::default_hook::{{closure}}::hf0801f6b18a968d3 10: 0x56499698d4ac - std::panicking::default_hook::hd2defec7eda5aeb0 11: 0x56499698dc31 - std::panicking::rust_panic_with_hook::hde93283600065c53 12: 0x56499698daf3 - std::panicking::begin_panic_handler::{{closure}}::h5e151adbdb7ec0c1 13: 0x56499698ca59 - std::sys_common::backtrace::__rust_end_short_backtrace::he36a1407e0f77700 14: 0x56499698d7d4 - rust_begin_unwind 15: 0x5649969a9503 - core::panicking::panic_fmt::h2380d41365f95412 16: 0x5649969a958c - core::panicking::panic::h38cf8db80e8c6e67 17: 0x5649969a93e9 - core::option::unwrap_failed::he72696e53ff29a05 18: 0x5649969722b6 - core::option::Option<T>::unwrap::hb574dc0dc1703062 19: 0x5649969722b6 - example::main::h7a867aafacd93d75 20: 0x5649969721db - core::ops::function::FnOnce::call_once::h734f99a5e57291b7 21: 0x56499697226e - std::sys_common::backtrace::__rust_begin_short_backtrace::h02f5d58c351c4756 22: 0x564996972241 - std::rt::lang_start::{{closure}}::h8b134fe2c31a4355 23: 0x564996988662 - core::ops::function::impls::<impl core::ops::function::FnOnce<A> for &F>::call_once::h88d7bb571ee2aaf4 24: 0x564996988662 - std::panicking::try::do_call::hfb78dfb6599c871d 25: 0x564996988662 - std::panicking::try::habd041c8c4c8e50c 27: 0x564996988662 - std::rt::lang_start_internal::{{closure}}::h227591a6f9c0879e 28: 0x564996988662 - std::panicking::try::do_call::h3c5878333c38916a 29: 0x564996988662 - std::panicking::try::h5af7b3a127cdae70 31: 0x564996988662 - std::rt::lang_start_internal::hbc85e809eeace0dd 32: 0x56499697221a - std::rt::lang_start::ha1eb16922c9cb224 33: 0x5649969722ee - main 34: 0x7f031962a1ca - __libc_start_call_main 35: 0x7f031962a28b - __libc_start_main_impl 36: 0x5649969720a5 - _start 37: 0x0 - <unknown> ``` </details> note particularly frames 13-21, from start_backtrace to end_backtrace. with PrintFmt::Short, these are the *only* frames that are printed; i.e. we are doing the exact opposite of the comment. r? ``@saethlin``

clarify simd_relaxed_fma non-determinism This is the safer spec in the sense that it is more likely to be satisfied by the backend -- and if people are okay with a non-deterministic result, I assume they don't care whether it's the same choice across all lanes or not?
