Remove linuxkernel targets by alex · Pull Request #104015 · rust-lang/rust (original) (raw)

Pkgsrc changes:

• Adjust patches (add & remove) and cargo checksums to new versions.
• It's conceivable that the workaround for LLVM based NetBSD works even less in this version (ref. PKGSRC_HAVE_LIBCPP not having a corresponding patch anymore).

Upstream changes:

Version 1.68.2 (2023-03-28)

• [Update the GitHub RSA host key bundled within Cargo] (rust-lang/cargo#11883). The key was [rotated by GitHub] (https://github.blog/2023-03-23-we-updated-our-rsa-ssh-host-key/) on 2023-03-24 after the old one leaked.
• [Mark the old GitHub RSA host key as revoked] (rust-lang/cargo#11889). This will prevent Cargo from accepting the leaked key even when trusted by the system.
• [Add support for @revoked and a better error message for @cert-authority in Cargo's SSH host key verification] (rust-lang/cargo#11635)

Version 1.68.1 (2023-03-23)

• [Fix miscompilation in produced Windows MSVC artifacts] (rust-lang/rust#109094) This was introduced by enabling ThinLTO for the distributed rustc which led to miscompilations in the resulting binary. Currently this is believed to be limited to the -Zdylib-lto flag used for rustc compilation, rather than a general bug in ThinLTO, so only rustc artifacts should be affected.
• [Fix --enable-local-rust builds] (rust-lang/rust#109111)
• [Treat $prefix-clang as clang in linker detection code] (rust-lang/rust#109156)
• [Fix panic in compiler code] (rust-lang/rust#108162)

Version 1.68.0 (2023-03-09)

Language

• [Stabilize default_alloc_error_handler] (rust-lang/rust#102318) This allows usage of alloc on stable without requiring the definition of a handler for allocation failure. Defining custom handlers is still unstable.

• [Remove implicit promotion for types with drop glue] (rust-lang/rust#105085)

Compiler

• [Always check alignment during compile-time const evaluation] (rust-lang/rust#104616)
• [Disable "split dwarf inlining" by default.] (rust-lang/rust#106709)

• [Implement DerefMut for PathBuf] (rust-lang/rust#105018)
• [Add O(1) Vec -> VecDeque conversion guarantee] (rust-lang/rust#105128)
• [Leak amplification for peek_mut() to ensure BinaryHeap's invariant is always met] (rust-lang/rust#105851)

Stabilized APIs

• [{core,std}::pin::pin!] (https://doc.rust-lang.org/stable/std/pin/macro.pin.html)
• [impl From<bool> for {f32,f64}] (https://doc.rust-lang.org/stable/std/primitive.f32.html#impl-From%3Cbool%3E-for-f32)

• [Don't build compiler_builtins with -C panic=abort.] (rust-lang/rust#103786)

Stabilized APIs

• [{integer}::checked_ilog] (https://doc.rust-lang.org/stable/std/primitive.i32.html#method.checked_ilog)
• [{integer}::checked_ilog2] (https://doc.rust-lang.org/stable/std/primitive.i32.html#method.checked_ilog2)

• [core::char::from_digit] (https://doc.rust-lang.org/stable/core/char/fn.from_digit.html)

Compatibility Notes

• [The layout of repr(Rust) types now groups m*2^n-sized fields with equivalently aligned ones.] (rust-lang/rust#102750) This is intended to be an optimization, but it is also known to increase type sizes in a few cases for the placement of enum tags. As a reminder, the layout of repr(Rust) types is an implementation detail, subject to change.
• [0.5 now rounds to 0 when formatted to 0 decimal places.] (rust-lang/rust#102935) This makes it consistent with the rest of floating point formatting that rounds ties toward even digits.
• [Chains of && and || will now drop temporaries from their sub-expressions in evaluation order, left-to-right.] (rust-lang/rust#103293) Previously, it was "twisted" such that the first expression dropped its temporaries last, after all of the other expressions dropped in order.
• [Underscore suffixes on string literals are now a hard error.] (rust-lang/rust#103914) This has been a future-compatibility warning since 1.20.0.
• [Stop passing -export-dynamic to wasm-ld.] (rust-lang/rust#105405)
• [main is now mangled as __main_void on wasm32-wasi.] (rust-lang/rust#105468)
• [Cargo now emits an error if there are multiple registries in the configuration with the same index URL.] (rust-lang/cargo#10592)
