2025-09-03rustdoc-search: yet another stringdex optimization attemptMichael Howell-162/+645
This one's uses a different tactic. It shouldn't significantly increase the amount of downloaded index data, but still reduces the amount of disk usage. This one works by changing the suffix-only node representation to omit some data that's needed for checking. Since those nodes make up the bulk of the tree, it reduces the data they store, but also requires validating the match by fetching the name itself (but the names list is pretty small, and when I tried it with wordnet "indexing" it was about the same).

Make bootstrap self test parallel This PR refactors the bootstrap self test: 1. Replaced the hardcoded --test-threads=1 with std::thread::available_parallelism(), allowing tests to run with the maximum concurrency supported by the system. 2. Replaced custom hacks around OUT_DIR with TempDir and introduced TestCtx to simplify configuration setup. r? `@Kobzol`

fix(rustdoc): match rustc `--emit` precedence Resolves rust-lang/rust#141664 This changes rustdoc's `--emit` to allow only one instance of each type, regardless of the actual data that `--emit` carries. This matches rustc's `--emit` behavior. As of the writing, only `dep-info` emit type carries extra data.

2025-09-03don't uppercase error messagesSasha Pourcelot-1/+1
a more general version of https://github.com/rust-lang/rust/pull/146080. after a bit of hacking in [`fluent.rs`](https://github.com/rust-lang/rust/blob/master/compiler/rustc_fluent_macro/src/fluent.rs), i discovered that i'm not the only one that is bad at following guidelines :sweat_smile:. this pr lowercases the first letter of all the error messages in the codebase. (i did not change things that are traditionally uppercased such as _MIR_, _ABI_ or _C_) i think it's reasonable to run a `@bors try` so all the test suite is checked, as i cannot run some of the tests on my machine. i double checked (and replaced manually) all the old error messages, but better be safe than sorry. in the future i will try to add a check in `x test tidy` that errors if an error message starts with an uppercase letter.

2025-09-03Rollup merge of #145944 - alexcrichton:native-wasip2, r=tgross35Stuart Cook-1/+15
std: Start supporting WASIp2 natively This commit is the start of an effort to support WASIp2 natively in the standard library. Before this commit the `wasm32-wasip2` target behaved exactly like `wasm32-wasip1` target by importing APIs from the core wasm module `wasi_snapshot_preview1`. These APIs are satisfied by the `wasm-component-ld` target by using an [adapter] which implements WASIp1 in terms of WASIp2. This adapter comes at a cost, however, in terms of runtime indirection and instantiation cost, so ideally the adapter would be removed entirely. The purpose of this adapter was to provide a smoother on-ramp from WASIp1 to WASIp2 when it was originally created. The `wasm32-wasip2` target has been around for long enough now that it's much more established. Additionally the only thing historically blocking using WASIp2 directly was implementation effort. Work is now underway to migrate wasi-libc itself to using WASIp2 directly and now seems as good a time as any to migrate the Rust standard library too. Implementation-wise the milestones here are: * The `wasm32-wasip2` target now also depends on the `wasi` crate at version 0.14.* in addition to the preexisting dependency of 0.11.*. The 0.14.* release series binds WASIp2 APIs instead of WASIp1 APIs. * Some preexisting naming around `mod wasi` or `wasi.rs` was renamed to `wasip1` where appropriate. For example `std::sys::pal::wasi` is now called `std::sys::pal::wasip1`. * More platform-specific WASI modules are now split between WASIp1 and WASIp2. For example getting the current time, randomness, and process arguments now use WASIp2 APIs directly instead of using WASIp1 APIs that require an adapter. It's worth pointing out that this PR does not migrate the entire standard library away from using WASIp1 APIs on the `wasm32-wasip2` target. Everything related to file descriptors and filesystem APIs is still using WASIp1. Migrating that is left for a future PR. In the meantime the goal of this change is to lay the groundwork necessary for migrating in the future. Eventually the goal is to drop the `wasi` 0.11.* dependency on the `wasm32-wasip2` target (the `wasm32-wasip1` target will continue to retain this dependency).
