2025-01-28uefi: process: Fix argsAyush Singh-4/+3
- While working on process env support, I found that args were currently broken. Not sure how I missed it in the PR, but well here is the fix. - Additionally, no point in adding space at the end of args. Signed-off-by: Ayush Singh <ayush@beagleboard.org>
2025-01-13uefi: helpers: Introduce OwnedDevicePathAyush Singh-7/+16
This PR is split off from #135368 to reduce noise. Rename DevicePath to OwnedDevicePath. This is to allow a non-owning version of DevicePath in the future to work with UEFI shell APIs which provide const pointers to device paths for UEFI shell fs mapping. Also implement Debug for OwnedDevicePath for some quality of life improvements. Signed-off-by: Ayush Singh <ayush@beagleboard.org>
2025-01-10Initial fs module for uefiAyush Singh-1/+344
- Just a copy of unsupported fs right now to reduce the noise from future PRs to allow for easier review. - For the full working version of fs on uefi, see [0] [0]: https://github.com/Ayush1325/rust/tree/uefi-file-full Signed-off-by: Ayush Singh <ayush@beagleboard.org>

2024-07-26Fix doc nitsJohn Arundel-6/+8
Many tiny changes to stdlib doc comments to make them consistent (for example "Returns foo", rather than "Return foo", per RFC1574), adding missing periods, paragraph breaks, backticks for monospace style, and other minor nits. https://github.com/rust-lang/rfcs/blob/master/text/1574-more-api-documentation-conventions.md#appendix-a-full-conventions-text

2024-07-16uefi: Forbid unwrapped unsafe in platform modulesJubilee Young-0/+1
2024-06-15std: refactor the TLS implementationjoboet-2/+0
As discovered by Mara in #110897, our TLS implementation is a total mess. In the past months, I have simplified the actual macros and their expansions, but the majority of the complexity comes from the platform-specific support code needed to create keys and register destructors. In keeping with #117276, I have therefore moved all of the `thread_local_key`/`thread_local_dtor` modules to the `thread_local` module in `sys` and merged them into a new structure, so that future porters of `std` can simply mix-and-match the existing code instead of having to copy the same (bad) implementation everywhere. The new structure should become obvious when looking at `sys/thread_local/mod.rs`. Unfortunately, the documentation changes associated with the refactoring have made this PR rather large. That said, this contains no functional changes except for two small ones: * the key-based destructor fallback now, by virtue of sharing the implementation used by macOS and others, stores its list in a `#[thread_local]` static instead of in the key, eliminating one indirection layer and drastically simplifying its code. * I've switched over ZKVM (tier 3) to use the same implementation as WebAssembly, as the implementation was just a way worse version of that Please let me know if I can make this easier to review! I know these large PRs aren't optimal, but I couldn't think of any good intermediate steps. @rustbot label +A-thread-locals
2024-06-05Raise `DEFAULT_MIN_STACK_SIZE` to at least 64KiBJubilee Young-1/+1
Prevent copy-paste errors from producing new starved-for-resources threaded platforms by raising `DEFAULT_MIN_STACK_SIZE` from 4096 bytes to at least 64KiB. Two platforms "affected" by this have no actual threads: - UEFI - "unsupported" Platforms that this actually affects: - wasm32-wasi with "atomics" enabled - wasm32-wasi-p1-threads Two exceptions: - SGX: a "secure code execution" platform, stays at 4096B - TEEOS: also a "secure code execution" platform, stays at 8192B I believe either of these may have sufficiently "interesting" semantics around threads, or significant external library support. Either would mean making any choices here for them is suspect.
2024-05-29Make `std::env::{set_var, remove_var}` unsafe in edition 2024Tobias Bucher-2/+2
Allow calling these functions without `unsafe` blocks in editions up until 2021, but don't trigger the `unused_unsafe` lint for `unsafe` blocks containing these functions. Fixes #27970. Fixes #90308. CC #124866.

2024-03-02Rollup merge of #121666 - ChrisDenton:thread-name, r=cuviperMatthias Krüger-1/+5
Use the OS thread name by default if `THREAD_INFO` has not been initialized Currently if `THREAD_INFO` hasn't been initialized then the name will be set to `None`. This PR changes it to use the OS thread name by default. This mostly affects foreign threads at the moment but we could expand this to make more use of the OS thread name in the future. Note: I've only implemented `Thread::get_name` for windows, linux and macos (and macos adjacent) targets. The rest just return `None`.

2024-03-01Auto merge of #114016 - krtab:delete_sys_memchr, r=workingjubileebors-4/+0
Delete architecture-specific memchr code in std::sys Currently all architecture-specific memchr code is only used in `std::io`. Most of the actual `memchr` capacity exposed to the user through the slice API is instead implemented in `core::slice::memchr`. Hence this commit deletes `memchr` from `std::sys[_common]` and replace calls to it by calls to `core::slice::memchr` functions. This deletes `(r)memchr` from the list of symbols linked to libc. The interest of putting architecture specific code back in core is linked to the discussion to be had in #113654
