docs: wrong naming convention in struct keyword doc Noticed that the naming convention mentioned is not the right one. As far as I know, PacalCase is the naming convention used for structs names. PacalCase is not the same as camelCase

Explain the default panic hook better This changes the documentation of `std::panic::set_hook` and `take_hook` to explain how the default panic hook works. In particular the fact that `take_hook` registers the default hook, rather than no hook at all, was missing from the docs. I also reworded a few things for clarity.

This allows loading some essential functions (e.g. read/write file) at load time instead of lazily.

This allows to skip an unnecessary buffer initialization.

2023-02-18Auto merge of #107329 - joboet:optimize_lazylock, r=m-ou-sebors-17/+120
Optimize `LazyLock` size The initialization function was unnecessarily stored separately from the data to be initialized. Since both cannot exist at the same time, a `union` can be used, with the `Once` acting as discriminant. This unfortunately requires some extra methods on `Once` so that `Drop` can be implemented correctly and efficiently. `@rustbot` label +T-libs +A-atomic

Use id-based thread parking on SOLID By using the [`slp_tsk`/`wup_tsk`](https://cs.uwaterloo.ca/~brecht/courses/702/Possible-Readings/embedded/uITRON-4.0-specification.pdf) system functions instead of an event-flag structure, `Parker` becomes cheaper to construct and SOLID can share the implementation used by NetBSD and SGX. ping ``@kawadakk`` r? ``@m-ou-se`` ``@rustbot`` label +T-libs

Update the minimum external LLVM to 14 With this change, we'll have stable support for LLVM 14 through 16 (pending release). For reference, the previous increase to LLVM 13 was #100460.
2023-02-13Rollup merge of #107985 - alesito85:master, r=ChrisDentonMatthias Krüger-1/+6
Added another error to be processed in fallback This pull request addresses the problem of Rust not being able to read file/directory metadata because the current user doesn't have permission to read the file and are thus inaccessible. One particular example is `System Volume Information`. But any example can be made by having a file/directory, which the current user can't access even though the system does allow to view the metadata, which is handled by the fallback. The fallback exists to get the metadata but it was limited to one error type. Having added ERROR_ACCESS_DENIED per Chris Denton's suggestion, file/directory properties are now properly read.

2023-02-12Auto merge of #105671 - lukas-code:depreciate-char, r=scottmcmbors-5/+4
Use associated items of `char` instead of freestanding items in `core::char` The associated functions and constants on `char` have been stable since 1.52 and the freestanding items have soft-deprecated since 1.62 (https://github.com/rust-lang/rust/pull/95566). This PR ~~marks them as "deprecated in future", similar to the integer and floating point modules (`core::{i32, f32}` etc)~~ replaces all uses of `core::char::*` with `char::*` to prepare for future deprecation of `core::char::*`.

2023-02-11Rollup merge of #106001 - sdroege:glibc-skip-over-null-argv, r=ChrisDentonDylan DPC-6/+22
Stop at the first `NULL` argument when iterating `argv` Some C commandline parsers (e.g. GLib and Qt) are replacing already handled arguments in `argv` with `NULL` and move them to the end. That means that `argc` might be bigger than the actual number of non-`NULL` pointers in `argv` at this point. To handle this we simply stop iterating at the first `NULL` argument. `argv` is also guaranteed to be `NULL`-terminated so any non-`NULL` arguments after the first `NULL` can safely be ignored. Fixes https://github.com/rust-lang/rust/issues/105999

2023-02-09Allow wasi-libc to initialize its environment variables lazily.Dan Gohman-1/+7
Use `__wasilibc_get_environ()` to read the environment variable list from wasi-libc instead of using `environ`. `environ` is a global variable which effectively requires wasi-libc to initialize the environment variables eagerly, and `__wasilibc_get_environ()` is specifically designed to be an alternative that lets wasi-libc intiailize its environment variables lazily. This should have the side effect of fixing at least some of the cases of #107635.
2023-02-08Rollup merge of #107429 - tgross35:from-bytes-until-null-stabilization, ↵Michael Goulet-1/+0
r=dtolnay Stabilize feature `cstr_from_bytes_until_nul` This PR seeks to stabilize `cstr_from_bytes_until_nul`. Partially addresses #95027 This function has only been on nightly for about 10 months, but I think it is simple enough that there isn't harm discussing stabilization. It has also had at least a handful of mentions on both the user forum and the discord, so it seems like it's already in use or at least known. This needs FCP still. Comment on potential discussion points: - eventual conversion of `CStr` to be a single thin pointer: this function will still be useful to provide a safe way to create a `CStr` after this change. - should this return a length too, to address concerns about the `CStr` change? I don't see it as being particularly useful, and it seems less ergonomic (i.e. returning `Result<(&CStr, usize), FromBytesUntilNulError>`). I think users that also need this length without the additional `strlen` call are likely better off using a combination of other methods, but this is up for discussion - `CString::from_vec_until_nul`: this is also useful, but it doesn't even have a nightly implementation merged yet. I propose feature gating that separately, as opposed to blocking this `CStr` implementation on that Possible alternatives: A user can use `from_bytes_with_nul` on a slice up to `my_slice[..my_slice.iter().find(|c| c == 0).unwrap()]`. However; that is significantly less ergonomic, and is a bit more work for the compiler to optimize compared the direct `memchr` call that this wraps. ## New stable API ```rs // both in core::ffi pub struct FromBytesUntilNulError(()); impl CStr { pub const fn from_bytes_until_nul( bytes: &[u8] ) -> Result<&CStr, FromBytesUntilNulError> } ``` cc ```@ericseppanen``` original author, ```@Mark-Simulacrum``` original reviewer, ```@m-ou-se``` brought up some issues on the thin pointer CStr ```@rustbot``` modify labels: +T-libs-api +needs-fcp
