2024-02-18By tracking import use types to check whether it is scope uses or the other ↵surechen-1/+0
situations like module-relative uses, we can do more accurate redundant import checking. fixes #117448 For example unnecessary imports in std::prelude that can be eliminated: ```rust use std::option::Option::Some;//~ WARNING the item `Some` is imported redundantly use std::option::Option::None; //~ WARNING the item `None` is imported redundantly ```

Revert outdated version of "Add the wasm32-wasi-preview2 target" An outdated version of #119616 was merged in rollup #120309. This reverts those changes to enable #119616 to “retain the intended diff” after a rebase. ```@rylev``` has agreed that this would be the cleanest approach with respect to the history. Unblocks #119616. r? ```@petrochenkov``` or compiler or libs
2024-01-30Rollup merge of #120452 - alexcrichton:update-windows-seek-write-docs, ↵Guillaume Gomez-1/+1
r=ChrisDenton std: Update documentation of seek_write on Windows Currently the documentation of `FileExt::seek_write` on Windows indicates that writes beyond the end of the file leave intermediate bytes uninitialized. This commentary dates back to the original inclusion of these functions in #35704 (wow blast from the past!). At the time the functionality here was implemented using `WriteFile`, but nowadays the `NtWriteFile` method is used instead. The documentation for `NtWriteFile` explicitly states: > If Length and ByteOffset specify a write operation past the current > end-of-file mark, NtWriteFile automatically extends the file and updates > the end-of-file mark; any bytes that are not explicitly written between > such old and new end-of-file marks are defined to be zero. This commentary has had a downstream impact in the `system-interface` crate where it tries to handle this by explicitly writing zeros, but I don't believe that's necessary any more. I'm sending a PR upstream here to avoid future confusion and codify that zeros are written in the intermediate bytes matching what Windows currently provides.

xous: misc fixes + add network support This patchset makes several fixes to Xous support. Additionally, this patch adds networking support. Many of these fixes are the result of the recent patch to get `unwinding` support merged. As a result of this patch, we can now run rust tests. As a result of these tests, we now have 729 tests passing: ``` failures: env::tests::test env::tests::test_self_exe_path env::tests::vars_debug env::tests::vars_os_debug os::raw::tests::same path::tests::test_push path::tests::test_set_file_name time::tests::since_epoch test result: FAILED. 729 passed; 8 failed; 1 ignored; 0 measured; 0 filtered out; finished in 214.54s ``` In the course of fixing several tests and getting the test sequence to reliably run, several issues were found. This patchset fixes those issues.

kmc-solid: I/O safety Adds the I/O safety API (#87329) for socket file descriptors in [`*-kmc-solid_*`](https://doc.rust-lang.org/nightly/rustc/platform-support/kmc-solid.html) Tier 3 targets. All new public items are gated by the `solid_ext` library feature. This PR adds the following public types and traits: std::os::solid::io::AsFd std::os::solid::io::BorrowedFd std::os::solid::io::OwnedFd std::os::solid::prelude::AsFd (re-export) std::os::solid::prelude::BorrowedFd (re-export) std::os::solid::prelude::OwnedFd (re-export) And trait implementations: From<std::net::TcpListener> for std::os::solid::io::OwnedFd From<std::net::TcpStream> for std::os::solid::io::OwnedFd From<std::net::UdpSocket> for std::os::solid::io::OwnedFd From<std::os::solid::io::OwnedFd> for std::net::TcpListener From<std::os::solid::io::OwnedFd> for std::net::TcpStream From<std::os::solid::io::OwnedFd> for std::net::UdpSocket std::fmt::Debug for std::os::solid::io::BorrowedFd<'_> std::fmt::Debug for std::os::solid::io::OwnedFd std::io::IsTerminal for std::os::solid::io::BorrowedFd<'_> std::io::IsTerminal for std::os::solid::io::OwnedFd std::os::fd::AsRawFd for std::os::solid::io::BorrowedFd<'_> std::os::fd::AsRawFd for std::os::solid::io::OwnedFd std::os::fd::FromRawFd for std::os::solid::io::OwnedFd std::os::fd::IntoRawFd for std::os::solid::io::OwnedFd std::os::solid::io::AsFd for &impl std::os::solid::io::AsFd std::os::solid::io::AsFd for &mut impl std::os::solid::io::AsFd std::os::solid::io::AsFd for Arc<impl std::os::solid::io::AsFd> std::os::solid::io::AsFd for Box<impl std::os::solid::io::AsFd> std::os::solid::io::AsFd for Rc<impl std::os::solid::io::AsFd> std::os::solid::io::AsFd for std::net::TcpListener std::os::solid::io::AsFd for std::net::TcpStream std::os::solid::io::AsFd for std::net::UdpSocket std::os::solid::io::AsFd for std::os::solid::io::BorrowedFd<'_> std::os::solid::io::AsFd for std::os::solid::io::OwnedFd Taking advantage of the above change, this PR also refactors the internal details of `std::sys::solid::net` to match the design of other targets, e.g., by redefining `Socket` as a newtype of `OwnedFd`.
2023-11-22unnecessary_mut_passedChris Denton-2/+2
This is where our Windows API bindings previously (and incorrectly) used `*mut` instead of `*const` pointers. Now that the bindings have been corrected, the mutable references (which auto-convert to `*mut`) are unnecessary and we can use shared references.

Remove asmjs Fulfills [MCP 668](https://github.com/rust-lang/compiler-team/issues/668). `asmjs-unknown-emscripten` does not work as-specified, and lacks essential upstream support for generating asm.js, so it should not exist at all.

2023-10-25Convert `Unix{Datagram,Stream}::{set_}passcred()` to per-OS traitsJohn Millikin-128/+230
These methods are the pre-stabilized API for obtaining peer credentials from an `AF_UNIX` socket, part of the `unix_socket_ancillary_data` feature. Their current behavior is to get/set one of the `SO_PASSCRED` (Linux), `LOCAL_CREDS_PERSISTENT` (FreeBSD), or `LOCAL_CREDS` (NetBSD) socket options. On other targets the `{set_}passcred()` methods do not exist. There are two problems with this approach: 1. Having public methods only exist for certain targets isn't permitted in a stable `std` API. 2. These options have generally similar purposes, but they are non-POSIX and their details can differ in subtle and surprising ways (such as whether they continue to be set after the next call to `recvmsg()`). Splitting into OS-specific extension traits is the preferred solution to both problems.
