Remove unused std::sys_common::thread_local_key::Key Part of https://github.com/rust-lang/rust/issues/110897 This `Key` type seems unused. Let's remove it and see if anything explodes. :)

Document `const {}` syntax for `std::thread_local`. It exists and is pretty cool. More people should use it. It was added in #83416 and stabilized in #91355 with the tracking issue #84223.
2023-04-28remove_dir_all: delete directory with fewer permsChris Denton-19/+22
If opening a directory with `FILE_LIST_DIRECTORY` access fails then we should try opening without requesting that access. We may still be able to delete it if it's empty or a link.
2023-04-27Rollup merge of #106599 - MikailBag:patch-1, r=jyn514Matthias Krüger-4/+4
Change memory ordering in System wrapper example Currently, the `SeqCst` ordering is used, which seems unnecessary: + Even `Relaxed` ordering guarantees that all updates are atomic and are executed in total order + User code only reads atomic for monitoring purposes, no "happens-before" relationships with actual allocations and deallocations are needed for this If argumentation above is correct, I propose changing ordering to `Relaxed` to clarify that no synchronization is required here, and improve performance (if somebody copy-pastes this example into their code).
2023-04-27Rollup merge of #106456 - kadiwa4:std-prelude-comment, r=jyn514Matthias Krüger-4/+4
Correct `std::prelude` comment (Read the changed file first for context.) First, `alloc` has no prelude. Second, the docs for `v1` don't matter since the [prelude module] already has all the doc links. The `rust_2021` module for instance also doesnt have a convenient doc page. However as I understand glob imports still cant be used because the items dont have the same stabilisation versions. [prelude module]: https://doc.rust-lang.org/std/prelude/index.html

docs(std): clarify remove_dir_all errors When using `remove_dir_all`, I assumed that the function was idempotent and that I could always call it to remove a directory if it existed. That's not the case and it bit me in production, so I figured I'd submit this to clarify the docs.

Restructure and rename std thread_local internals to make it less of a maze Every time I try to work on std's thread local internals, it feels like I'm trying to navigate a confusing maze made of macros, deeply nested modules, and types with multiple names/aliases. Time to clean it up a bit. This PR: - Exports `Key` with its own name (`Key`), instead of `__LocalKeyInner` - Uses `pub macro` to put `__thread_local_inner` into a (unstable, hidden) module, removing `#[macro_export]`, removing it from the crate root. - Removes the `__` from `__thread_local_inner`. - Removes a few unnecessary `allow_internal_unstable` features from the macros - Removes the `libstd_thread_internals` feature. (Merged with `thread_local_internals`.) - And removes it from the unstable book - Gets rid of the deeply nested modules for the `Key` definitions (`mod fast` / `mod os` / `mod statik`). - Turns a `#[cfg]` mess into a single `cfg_if`, now that there's no `#[macro_export]` anymore that breaks with `cfg_if`. - Simplifies the `cfg_if` conditions to not repeat the conditions. - Removes useless `normalize-stderr-test`, which were left over from when the `Key` types had different names on different platforms. - Removes a seemingly unnecessary `realstd` re-export on `cfg(test)`. This PR changes nothing about the thread local implementation. That's for a later PR. (Which should hopefully be easier once all this stuff is a bit cleaned up.)

2023-04-26Rollup merge of #110587 - tomaka:fix-109727, r=jyn514jyn-2/+7
Fix `std` compilation error for wasi+atomics Fix https://github.com/rust-lang/rust/issues/109727 It seems that the `unsupported/once.rs` module isn't meant to exist at the same time as the `futex` module, as they have conflicting definitions. I've solved this by defining the `once` module only if `not(target_feature = "atomics")`. The `wasm32-unknown-unknown` target [similarly only defines the `once` module if `not(target_feature = "atomics")`](https://github.com/tomaka/rust/blob/01c4f319276da912dd2be768ae0ce9857ad6bb63/library/std/src/sys/wasm/mod.rs#L69-L70). As show in [this block of code](https://github.com/tomaka/rust/blob/01c4f319276da912dd2be768ae0ce9857ad6bb63/library/std/src/sys_common/once/mod.rs#L10-L34), the `sys::once` module doesn't need to exist if `all(target_arch = "wasm32", target_feature = "atomics")`.

2023-04-23Auto merge of #110655 - ChrisDenton:read-to-end, r=joshtriplettbors-24/+43
Limit read size in `File::read_to_end` loop Fixes #110650. Windows file reads have perf overhead that's proportional to the buffer size. When we have a reasonable expectation that we know the file size, we can set a reasonable upper bound for the size of the buffer in one read call.
2023-04-22Auto merge of #109507 - Amanieu:panic-oom-payload, r=davidtwcobors-93/+29
Report allocation errors as panics OOM is now reported as a panic but with a custom payload type (`AllocErrorPanicPayload`) which holds the layout that was passed to `handle_alloc_error`. This should be review one commit at a time: - The first commit adds `AllocErrorPanicPayload` and changes allocation errors to always be reported as panics. - The second commit removes `#[alloc_error_handler]` and the `alloc_error_hook` API. ACP: https://github.com/rust-lang/libs-team/issues/192 Closes #51540 Closes #51245

2023-04-19std: make `Debug` representations of `[Lazy, Once]*[Cell, Lock]` consistent ↵joboet-20/+12
with `Mutex` and `RwLock` `Mutex` prints `<locked>` as a field value when its inner value cannot be accessed, but the lazy types print a fixed string like "`OnceCell(Uninit)`". This could cause confusion if the inner type is a unit type named `Uninit` and does not respect the pretty-printing flag. With this change, the format message is now "`OnceCell(<uninit>)`", consistent with `Mutex`.
