2025-03-14Rollup merge of #138457 - bjorn3:redox_scheme_paths, r=NoratriebJacob Pratt-14/+8
Remove usage of legacy scheme paths on RedoxOS The `name:/path` path syntax is getting phased out[^1] in favor of `/scheme/name/path`. Also using `null:` is no longer necessary as `/dev/null` is available on Redox OS too. [^1]: https://gitlab.redox-os.org/redox-os/rfcs/-/blob/master/text/0006-scheme-path.md cc `@jackpot51`

Improve HashMap docs for const and static initializers Closes #137566. I clarified the HashMap usage in const and static initializers. I also added examples of how to construct such HashMaps wrapped in LazyLock.
2025-03-14Rollup merge of #136001 - hkBst:patch-21, r=cuviperJacob Pratt-49/+75
Overhaul examples for PermissionsExt This fixes #91707 by including one overarching example, instead of the small examples that can be misleading.
2025-03-13Remove has_redox_schemebjorn3-11/+2
Redox OS is moving away from name:/path style paths to /scheme/name/path style paths which are already handled correctly without has_redox_scheme.
2025-03-13Rollup merge of #138425 - cuviper:remove-hash_raw_entry, r=jhprattMatthias Krüger-564/+0
Remove `feature = "hash_raw_entry"` The `hash_raw_entry` feature finished [fcp-close](https://github.com/rust-lang/rust/issues/56167#issuecomment-2293805510) back in August, and its remaining uses in the compiler have now been removed, so we should be all clear to remove it from `std`. Closes #56167

2025-03-13Rollup merge of #138370 - cuviper:try_oom_error, r=jhprattMatthias Krüger-6/+10
Simulate OOM for the `try_oom_error` test We can create the expected error manually, rather than trying to produce a real one, so the error conversion test can run on all targets. Before, it was only running on 64-bit and not miri. In Fedora, we also found that s390x was not getting the expected error, "successfully" allocating the huge size because it was optimizing the real `malloc` call away. It's possible to counter that by looking at the pointer in any way, like a debug print, but it's more robust to just deal with errors directly, since this test is only about conversion.

2025-03-13Rollup merge of #138162 - ehuss:library-2024, r=cuviperMatthias Krüger-2/+2
Update the standard library to Rust 2024 This updates the standard library to Rust 2024. This includes the following notable changes: - Macros are updated to use new expression fragment specifiers. This PR includes a test to illustrate the changes, primarily allowing `const {...}` expressions now. - Some tests show a change in MIR drop order. We do not believe this will be an observable change ([see zulip discussion](https://rust-lang.zulipchat.com/#narrow/channel/268952-edition/topic/standard.20library.20migration/near/500972873)).

Stabilize `std::io::ErrorKind::InvalidFilename` FCP complete: https://github.com/rust-lang/rust/issues/130192#issuecomment-2674989358 Tracking issues: #86442 & #130192 This PR: - Stabilizes `InvalidFilename` without changing its name to `InvalidFileName`. - Fixes the doc comment (https://github.com/rust-lang/rust/issues/130192#issuecomment-2429534640) - Does not separate "the name is too long" case into a separate `ErrorKind`. That case is currently documented to be covered by `InvalidFilename` in the doc. I'm not sure if it would be possible to change this later or if that would be an unacceptable breaking change. - Does not map more raw OS errors to this `ErrorKind` (as suggested in https://github.com/rust-lang/rust/issues/86442#issuecomment-1441709738). This can presumably be addressed later.

It reinterprets uninitialized memory as initialized and does not drop existing elements of the Vec. Fix that. Additionally, make it more general by appending, instead of overwriting existing elements, and rename it to `append_to_enclave_vec`. A caller can simply call `.clear()` before, for the old behavior.

2025-03-11Rollup merge of #138002 - 1c3t3a:fix-std-cfi-violation, r=rcvalleMatthias Krüger-0/+37
Disable CFI for weakly linked syscalls Currently, when enabling CFI via -Zsanitizer=cfi and executing e.g. std::sys::random::getrandom, we can observe a CFI violation. This is the case for all consumers of the std::sys::pal::weak::syscall macro, as it is defining weak functions which don't show up in LLVM IR metadata. CFI fails for all these functions. Similar to other such cases in https://github.com/rust-lang/rust/issues/115199, this change stops emitting the CFI typecheck for consumers of the macro via the `#[no_sanitize(cfi)]` attribute. r? ``````@rcvalle``````
2025-03-11Auto merge of #128440 - oli-obk:defines, r=lcnrbors-0/+10
Add `#[define_opaques]` attribute and require it for all type-alias-impl-trait sites that register a hidden type Instead of relying on the signature of items to decide whether they are constraining an opaque type, the opaque types that the item constrains must be explicitly listed. A previous version of this PR used an actual attribute, but had to keep the resolved `DefId`s in a side table. Now we just lower to fields in the AST that have no surface syntax, instead a builtin attribute macro fills in those fields where applicable. Note that for convenience referencing opaque types in associated types from associated methods on the same impl will not require an attribute. If that causes problems `#[defines()]` can be used to overwrite the default of searching for opaques in the signature. One wart of this design is that closures and static items do not have generics. So since I stored the opaques in the generics of functions, consts and methods, I would need to add a custom field to closures and statics to track this information. During a T-types discussion we decided to just not do this for now. fixes #131298

2025-03-10Implement default methods for io::Empty and io::SinkThalia Archibald-11/+216
Eliminate any redundant, unobservable logic from the their default method implementations. The observable changes are that `Write::write_fmt` for both types now ignores the formatting arguments, so a user fmt impl which has side effects is not invoked, and `Write::write_all_vectored` for both types does not advance the borrowed buffers. Neither behavior is guaranteed by the docs and the latter is documented as unspecified. `Empty` is not marked as vectored, so that `Chain<Empty, _>` and `Chain<_, Empty>` are not forced to be vectored.
