@bors r- This failed in #79057, as it causes an error in the reference, and tools cannot be broken the week before beta. The offending code is at https://github.com/rust-lang/reference/blob/e4e4972d013099a2c8eaed88680d7cb0bc7a688d/src/items/functions.md#attributes-on-functions One suggestion is to change that example in the reference to something else (maybe (FWIW, I'm not entirely clear why this change is being made, as it may break existing projects that use this. I don't see any on crates.io that do, so it's probably not a concern, but it seems a bit aggressive to outright deny it.) |
Marking as blocked until the end of the no-breakage week.

rustc_expand: Mark inner `#![test]` attributes as soft-unstable Custom inner attributes are feature gated (rust-lang#54726) except for attributes having name `test` literally, which are not gated for historical reasons. `#![test]` is an inner proc macro attribute, so it has all the issues described in rust-lang#54726 too. This PR gates it with the `soft_unstable` lint.

📣 Toolstate changed by #79003! Tested on commit 502c477. 💔 reference on windows: test-pass → test-fail (cc @matthewjasper @ehuss @steveklabnik @Havvy). |
Tested on commit rust-lang/rust@502c477. Direct link to PR: <rust-lang/rust#79003> 💔 reference on windows: test-pass → test-fail (cc @matthewjasper @ehuss @steveklabnik @Havvy). 💔 reference on linux: test-pass → test-fail (cc @matthewjasper @ehuss @steveklabnik @Havvy).
Using `test` causes a deny-by-default lint to trigger. See rust-lang/rust#79003 for more information.
Pkgsrc changes: * Adjust patches, re-compute line offsets, fix capitalization. * Remove i686/FreeBSD support, no longer provided upstream. * Bump bootstraps to 1.49.0. * Change USE_TOOLS from bsdtar to gtar. * Reduce diffs to pkgsrc-wip package patches. * Allow rust.BUILD_TARGET to override automatic choice of target. * Add an i586/NetBSD (pentium) bootstrap variant (needs testing), not yet added as bootstrap since 1.49 doesn't have that variant. Upstream changes: Version 1.50.0 (2021-02-11) ============================ Language ----------------------- - [You can now use `const` values for `x` in `[x; N]` array expressions.][79270] This has been technically possible since 1.38.0, as it was unintentionally stabilized. - [Assignments to `ManuallyDrop<T>` union fields are now considered safe.][78068] Compiler ----------------------- - [Added tier 3\* support for the `armv5te-unknown-linux-uclibceabi` target.][78142] - [Added tier 3 support for the `aarch64-apple-ios-macabi` target.][77484] - [The `x86_64-unknown-freebsd` is now built with the full toolset.][79484] \* Refer to Rust's [platform support page][forge-platform-support] for more information on Rust's tiered platform support. Libraries ----------------------- - [`proc_macro::Punct` now implements `PartialEq<char>`.][78636] - [`ops::{Index, IndexMut}` are now implemented for fixed sized arrays of any length.][74989] - [On Unix platforms, the `std::fs::File` type now has a "niche" of `-1`.][74699] This value cannot be a valid file descriptor, and now means `Option<File>` takes up the same amount of space as `File`. Stabilized APIs --------------- - [`bool::then`] - [`btree_map::Entry::or_insert_with_key`] - [`f32::clamp`] - [`f64::clamp`] - [`hash_map::Entry::or_insert_with_key`] - [`Ord::clamp`] - [`RefCell::take`] - [`slice::fill`] - [`UnsafeCell::get_mut`] The following previously stable methods are now `const`. - [`IpAddr::is_ipv4`] - [`IpAddr::is_ipv6`] - [`Layout::size`] - [`Layout::align`] - [`Layout::from_size_align`] - `pow` for all integer types. - `checked_pow` for all integer types. - `saturating_pow` for all integer types. - `wrapping_pow` for all integer types. - `next_power_of_two` for all unsigned integer types. - `checked_power_of_two` for all unsigned integer types. Cargo ----------------------- - [Added the `[build.rustc-workspace-wrapper]` option.][cargo/8976] This option sets a wrapper to execute instead of `rustc`, for workspace members only. - [`cargo:rerun-if-changed` will now, if provided a directory, scan the entire contents of that directory for changes.][cargo/8973] - [Added the `--workspace` flag to the `cargo update` command.][cargo/8725] Misc ---- - [The search results tab and the help button are focusable with keyboard in rustdoc.][79896] - [Running tests will now print the total time taken to execute.][75752] Compatibility Notes ------------------- - [The `compare_and_swap` method on atomics has been deprecated.][79261] It's recommended to use the `compare_exchange` and `compare_exchange_weak` methods instead. - [Changes in how `TokenStream`s are checked have fixed some cases where you could write unhygenic `macro_rules!` macros.][79472] - [`#![test]` as an inner attribute is now considered unstable like other inner macro attributes, and reports an error by default through the `soft_unstable` lint.][79003] - [Overriding a `forbid` lint at the same level that it was set is now a hard error.][78864] - [Dropped support for all cloudabi targets.][78439] - [You can no longer intercept `panic!` calls by supplying your own macro.][78343] It's recommended to use the `#[panic_handler]` attribute to provide your own implementation. - [Semi-colons after item statements (e.g. `struct Foo {};`) now produce a warning.][78296] [74989]: rust-lang/rust#74989 [79261]: rust-lang/rust#79261 [79896]: rust-lang/rust#79896 [79484]: rust-lang/rust#79484 [79472]: rust-lang/rust#79472 [79270]: rust-lang/rust#79270 [79003]: rust-lang/rust#79003 [78864]: rust-lang/rust#78864 [78636]: rust-lang/rust#78636 [78439]: rust-lang/rust#78439 [78343]: rust-lang/rust#78343 [78296]: rust-lang/rust#78296 [78068]: rust-lang/rust#78068 [75752]: rust-lang/rust#75752 [74699]: rust-lang/rust#74699 [78142]: rust-lang/rust#78142 [77484]: rust-lang/rust#77484 [cargo/8976]: rust-lang/cargo#8976 [cargo/8973]: rust-lang/cargo#8973 [cargo/8725]: rust-lang/cargo#8725 [`IpAddr::is_ipv4`]: https://doc.rust-lang.org/stable/std/net/enum.IpAddr.html#method.is_ipv4 [`IpAddr::is_ipv6`]: https://doc.rust-lang.org/stable/std/net/enum.IpAddr.html#method.is_ipv6 [`Layout::align`]: https://doc.rust-lang.org/stable/std/alloc/struct.Layout.html#method.align [`Layout::from_size_align`]: https://doc.rust-lang.org/stable/std/alloc/struct.Layout.html#method.from_size_align [`Layout::size`]: https://doc.rust-lang.org/stable/std/alloc/struct.Layout.html#method.size [`Ord::clamp`]: https://doc.rust-lang.org/stable/std/cmp/trait.Ord.html#method.clamp [`RefCell::take`]: https://doc.rust-lang.org/stable/std/cell/struct.RefCell.html#method.take [`UnsafeCell::get_mut`]: https://doc.rust-lang.org/stable/std/cell/struct.UnsafeCell.html#method.get_mut [`bool::then`]: https://doc.rust-lang.org/stable/std/primitive.bool.html#method.then [`btree_map::Entry::or_insert_with_key`]: https://doc.rust-lang.org/stable/std/collections/btree_map/enum.Entry.html#method.or_insert_with_key [`f32::clamp`]: https://doc.rust-lang.org/stable/std/primitive.f32.html#method.clamp [`f64::clamp`]: https://doc.rust-lang.org/stable/std/primitive.f64.html#method.clamp [`hash_map::Entry::or_insert_with_key`]: https://doc.rust-lang.org/stable/std/collections/hash_map/enum.Entry.html#method.or_insert_with_key [`slice::fill`]: https://doc.rust-lang.org/stable/std/primitive.slice.html#method.fill
