Starting FCP in parallel to the PR review @rfcbot fcp merge |
Team member @epage has proposed to merge this. The next step is review by the rest of the tagged team members: No concerns currently listed. Once a majority of reviewers approve (and at most 2 approvals are outstanding), this will enter its final comment period. If you spot a major issue that hasn't been raised at any point in this process, please speak up! See this document for info about what commands tagged team members can give me. |
PR rust-lang#5335 added `autobins`, etc for rust-lang#5330. Nowhere in there is discussion of `autolib`. Cargo script disables support for additional build-targets by disabling discovery. Except we don't have a way to disable discovery of `autolib`, leading to rust-lang#14476. By adding `autolib`, we can continue in that direction. This also allows us to bypass inferring of libs on published packages, like all other build-targets which were handled in rust-lang#13849. As this seems fairly low controversy, this insta-stabilizes the field. In prior versions of Cargo, users will get an "unused manifest key" warning. For packags where this is set by `cargo publish`, the warning will be suppressed and things will work as normal. For `cargo vendor`, the same except there will be some churn in the vendored source as this field will now be set. For local development, it should be rare to set `autolib` so the lack of error by discovering a file when this is set shouldn't be a problem. Fixes rust-lang#14476

Everything looks good, except this could potentially break other third-party build tools like cargo-manifest
in the future. I'd like to give them a heads-up in https://rust-lang.zulipchat.com/#narrow/stream/334885-t-cargo.2Fbuild-integration and merge on Friday. Any other opinion?

This adds support for parsing the new `autolib` member (rust-lang/cargo#14591). This is a quick and easy fix, suitable for backport. A larger more involved fix will be to stop splatting out the cargo dictionaries, and instead pass the fields we know about 1 by 1, and warning the user if we come across unknown fields. Fixes: mesonbuild#13826

[Added `package.autolib` to the manifest, allowing `[lib]` auto-discovery to be disabled.] (rust-lang/cargo#14591) - [Declare support level for each crate in Cargo's Charter / crate docs.] (rust-lang/cargo#14600) - [Declare new Intentional Artifacts as 'small' changes.] (rust-lang/cargo#14599) Rustdoc ------- - [The sidebar / hamburger menu table of contents now includes the `# headers` from the main item's doc comment] (rust-lang/rust#120736). This is similar to a third-party feature provided by the rustdoc-search-enhancements browser extension. Compatibility Notes ------------------- - [Warn against function pointers using unsupported ABI strings.] (rust-lang/rust#128784) - [Check well-formedness of the source type's signature in fn pointer casts.] (rust-lang/rust#129021) This partly closes a soundness hole that comes when casting a function item to function pointer - [Use equality instead of subtyping when resolving type dependent paths.] (rust-lang/rust#129073) - Linking on macOS now correctly includes Rust's default deployment target. Due to a linker bug, you might have to pass `MACOSX_DEPLOYMENT_TARGET` or fix your `#[link]` attributes to point to the correct frameworks. See <rust-lang/rust#129369>. - [Rust will now correctly raise an error for `repr(Rust)` written on non-`struct`/`enum`/`union` items, since it previous did not have any effect.] (rust-lang/rust#129422) - The future incompatibility lint `deprecated_cfg_attr_crate_type_name` [has been made into a hard error] (rust-lang/rust#129670). It was used to deny usage of `#![crate_type]` and `#![crate_name]` attributes in `#![cfg_attr]`, which required a hack in the compiler to be able to change the used crate type and crate name after cfg expansion. Users can use `--crate-type` instead of `#![cfg_attr(..., crate_type = "...")]` and `--crate-name` instead of `#![cfg_attr(..., crate_name = "...")]` when running `rustc`/`cargo rustc` on the command line. Use of those two attributes outside of `#![cfg_attr]` continue to be fully supported. - Until now, paths into the sysroot were always prefixed with `/rustc/$hash` in diagnostics, codegen, backtrace, e.g. ``` thread 'main' panicked at 'hello world', map-panic.rs:2:50 stack backtrace: 0: std::panicking::begin_panic at /rustc/a55dd71d5fb0ec5a6a3a9e8c27b2127ba491ce52/library/std/src/panicking.rs:616:12 1: map_panic::main::{{closure}} at ./map-panic.rs:2:50 2: core::option::Option<T>::map at /rustc/a55dd71d5fb0ec5a6a3a9e8c27b2127ba491ce52/library/core/src/option.rs:929:29 3: map_panic::main at ./map-panic.rs:2:30 4: core::ops::function::FnOnce::call_once at /rustc/a55dd71d5fb0ec5a6a3a9e8c27b2127ba491ce52/library/core/src/ops/function.rs:248:5 note: Some details are omitted, run with `RUST_BACKTRACE=full` for a verbose backtrace. ``` [RFC 3127 said] (https://rust-lang.github.io/rfcs/3127-trim-paths.html#changing-handling-of-sysroot-path-in-rustc) > We want to change this behaviour such that, when `rust-src` source files can be discovered, the virtual path is discarded and therefore the local path will be embedded, unless there is a `--remap-path-prefix` that causes this local path to be remapped in the usual way. [#129687](rust-lang/rust#129687) implements this behaviour, when `rust-src` is present at compile time, `rustc` replaces `/rustc/$hash` with a real path into the local `rust-src` component with best effort. To sanitize this, users must explicitly supply `--remap-path-prefix=<path to rust-src>=foo` or not have the `rust-src` component installed. - The allow-by-default `missing_docs` lint used to disable itself when invoked through `rustc --test`/`cargo test`, resulting in `#[expect(missing_docs)]` emitting false positives due to the expectation being wrongly unfulfilled. This behavior [has now been removed] (rust-lang/rust#130025), which allows `#[expect(missing_docs)]` to be fulfilled in all scenarios, but will also report new `missing_docs` diagnostics for publicly reachable `#[cfg(test)]` items, [integration test] (https://doc.rust-lang.org/cargo/reference/cargo-targets.html#integration-tests) crate-level documentation, and publicly reachable items in integration tests. - [The `armv8r-none-eabihf` target now uses the Armv8-R required set of floating-point features.] (rust-lang/rust#130295) - [Fix a soundness bug where rustc wouldn't detect unconstrained higher-ranked lifetimes in a `dyn Trait`'s associated types that occur due to supertraits.] (rust-lang/rust#130367) - [Update the minimum external LLVM version to 18.] (rust-lang/rust#130487) - [Remove `aarch64-fuchsia` and `x86_64-fuchsia` target aliases in favor of `aarch64-unknown-fuchsia` and `x86_64-unknown-fuchsia` respectively.] (rust-lang/rust#130657) - [The ABI-level exception class of a Rust panic is now encoded with native-endian bytes, so it is legible in hex dumps.] (rust-lang/rust#130897) - [Visual Studio 2013 is no longer supported for MSVC targets.] (rust-lang/rust#131070) - [The sysroot no longer contains the `std` dynamic library in its top-level `lib/` dir.] (rust-lang/rust#131188)

Due to a linker bug, you might have to pass `MACOSX_DEPLOYMENT_TARGET` or fix your `#[link]` attributes to point to the correct frameworks. See [#​129369](rust-lang/rust#129369). - [Rust will now correctly raise an error for `repr(Rust)` written on non-`struct`/`enum`/`union` items, since it previous did not have any effect.](rust-lang/rust#129422) - The future incompatibility lint `deprecated_cfg_attr_crate_type_name` [has been made into a hard error](rust-lang/rust#129670). It was used to deny usage of `#![crate_type]` and `#![crate_name]` attributes in `#![cfg_attr]`, which required a hack in the compiler to be able to change the used crate type and crate name after cfg expansion. Users can use `--crate-type` instead of `#![cfg_attr(..., crate_type = "...")]` and `--crate-name` instead of `#![cfg_attr(..., crate_name = "...")]` when running `rustc`/`cargo rustc` on the command line. Use of those two attributes outside of `#![cfg_attr]` continue to be fully supported. - Until now, paths into the sysroot were always prefixed with `/rustc/$hash` in diagnostics, codegen, backtrace, e.g. thread 'main' panicked at 'hello world', map-panic.rs:2:50 stack backtrace: 0: std::panicking::begin_panic at /rustc/a55dd71d5fb0ec5a6a3a9e8c27b2127ba491ce52/library/std/src/panicking.rs:616:12 1: map_panic::main::{{closure}} at ./map-panic.rs:2:50 2: core::option::Option<T>::map at /rustc/a55dd71d5fb0ec5a6a3a9e8c27b2127ba491ce52/library/core/src/option.rs:929:29 3: map_panic::main at ./map-panic.rs:2:30 4: core::ops::function::FnOnce::call_once at /rustc/a55dd71d5fb0ec5a6a3a9e8c27b2127ba491ce52/library/core/src/ops/function.rs:248:5 note: Some details are omitted, run with `RUST_BACKTRACE=full` for a verbose backtrace. [RFC 3127 said](https://rust-lang.github.io/rfcs/3127-trim-paths.html#changing-handling-of-sysroot-path-in-rustc) > We want to change this behaviour such that, when `rust-src` source files can be discovered, the virtual path is discarded and therefore the local path will be embedded, unless there is a `--remap-path-prefix` that causes this local path to be remapped in the usual way. [#​129687](rust-lang/rust#129687) implements this behaviour, when `rust-src` is present at compile time, `rustc` replaces `/rustc/$hash` with a real path into the local `rust-src` component with best effort. To sanitize this, users must explicitly supply `--remap-path-prefix=<path to rust-src>=foo` or not have the `rust-src` component installed. - The allow-by-default `missing_docs` lint used to disable itself when invoked through `rustc --test`/`cargo test`, resulting in `#[expect(missing_docs)]` emitting false positives due to the expectation being wrongly unfulfilled. This behavior [has now been removed](rust-lang/rust#130025), which allows `#[expect(missing_docs)]` to be fulfilled in all scenarios, but will also report new `missing_docs` diagnostics for publicly reachable `#[cfg(test)]` items, [integration test](https://doc.rust-lang.org/cargo/reference/cargo-targets.html#integration-tests) crate-level documentation, and publicly reachable items in integration tests. - [The `armv8r-none-eabihf` target now uses the Armv8-R required set of floating-point features.](rust-lang/rust#130295) - [Fix a soundness bug where rustc wouldn't detect unconstrained higher-ranked lifetimes in a `dyn Trait`'s associated types that occur due to supertraits.](rust-lang/rust#130367) - [Update the minimum external LLVM version to 18.](rust-lang/rust#130487) - [Remove `aarch64-fuchsia` and `x86_64-fuchsia` target aliases in favor of `aarch64-unknown-fuchsia` and `x86_64-unknown-fuchsia` respectively.](rust-lang/rust#130657) - [The ABI-level exception class of a Rust panic is now encoded with native-endian bytes, so it is legible in hex dumps.](rust-lang/rust#130897) - [Visual Studio 2013 is no longer supported for MSVC targets.](rust-lang/rust#131070) - [The sysroot no longer contains the `std` dynamic library in its top-level `lib/` dir.](rust-lang/rust#131188) </details> --- ### Configuration 📅 **Schedule**: Branch creation - At any time (no schedule defined), Automerge - At any time (no schedule defined). 🚦 **Automerge**: Disabled by config.

This adds support for parsing the new `autolib` member (rust-lang/cargo#14591). This is a quick and easy fix, suitable for backport. A larger more involved fix will be to stop splatting out the cargo dictionaries, and instead pass the fields we know about 1 by 1, and warning the user if we come across unknown fields. Fixes: #13826 (cherry picked from commit b131b2d)
What does this PR try to resolve?
PR #5335 added
autobins
, etc for #5330. Nowhere in there isdiscussion of
autolib
.Cargo script disables support for additional build-targets by disabling
discovery.
Except we don't have a way to disable discovery of
autolib
, leading to #14476.By adding
autolib
, we can continue in that direction.This also allows us to bypass inferring of libs on published packages,
like all other build-targets which were handled in #13849.
Fixes #14476
How should we test and review this PR?
Additional information
As this seems fairly low controversy, this insta-stabilizes the field.
In prior versions of Cargo, users will get an "unused manifest key"
warning.
For packages where this is set by
cargo publish
, the warning will be suppressed and things will work as normal.For
cargo vendor
, the same except there will be some churn in thevendored source as this field will now be set.
For local development, it should be rare to set
autolib
so the lack oferror by discovering a file when this is set shouldn't be a problem.
