The reasonthis was allowed was that when the workspace was first migrated theWasmtime crate had too many instances that I was willing to fix. I'venow come back around and tried to fix everything.In short: ideally delete `#[allow]`, otherwise use `#[expect]`,otherwise use `#[allow]`.prtest:full* Adjust some directives* Fix some warnings* Fix stack switching size tests on unix* Don't have a conditional `Drop` impl* Force `testing_freelist` method to be usedToo lazy to write `#[cfg]`, but not too lazy to write a test.

I intend to upstream them into theproposal shortly.There is a new `wasmtime::Config::wasm_custom_page_sizes_proposal` method toenable or disable the proposal. It is disabled by default.Our fuzzing config has been updated to turn this feature on/off as dictated bythe arbitrary input given to us from the fuzzer.Additionally, there were getting to be so many constructors for`wasmtime::MemoryType` that I added a builder rather than add yet anotherconstructor.In general, we store the `log2(page_size)` rather than the page sizedirectly. This helps cut down on invalid states and properties we need toassert.I've also intentionally written this code such that supporting any power of twopage size (rather than just the exact values `1` and `65536` that are currentlyvalid) will essentially just involve updating `wasmparser`'s validation andremoving some debug asserts in Wasmtime.* Update error string expectation* Remove debug logging* Use a right shift instead of a division* fix error message expectation again* remove page size from VMMemoryDefinition* fix size of VMMemoryDefinition again* Only dynamically check for `-1` sentinel for 1-byte page sizes* Import functions that are used a few times* Better handle overflows when rounding up to the host page sizePropagate errors instead of returning a value that is not actually a rounded upversion of the input.Delay rounding up various config sizes until runtime instead of eagerly doing itat config time (which isn't even guaranteed to work, so we already had to have abackup plan to round up at runtime, since we might be cross-compiling wasm ornot have the runtime feature enabled).* Fix some anyhow and nostd errors* Add missing rounding up to host page size at runtime* Add validate feature to wasmparser dep* Add some new rounding in a few places, due to no longer rounding in config methods* Avoid actually trying to allocate the whole address space in the `massive_64_bit_still_limited` testThe point of the test is to ensure that we hit the limiter, so just cancel theallocation from the limiter, and otherwise avoid MIRI attempting to allocate abunch of memory after we hit the limiter.* prtest:full* Revert "Avoid actually trying to allocate the whole address space in the `massive_64_bit_still_limited` test"This reverts commit ccfa34a78dd3d53e49a6158ca03077d42ce8bcd7.* miri: don't attempt to allocate more than 4GiB of memoryIt seems that rather than returning a null pointer from `std::alloc::alloc`,miri will sometimes choose to simply crash the whole program.* remove duplicate prelude import after rebasing List of files: /wasmtime-44.0.1/crates/wasmtime/src/runtime/vm/mpk/sys.rs Wed, 12 Jun 2024 21:46:42 +0000 Nick Fitzgerald <fitzgen@gmail.com> http://172.16.0.5:8080/history/wasmtime-44.0.1/crates/wasmtime/src/runtime/vm/mpk/sys.rs#81a89169 Add support for `#![no_std]` to the `wasmtime` crate (#8533)* Always fall back to custom platform for WasmtimeThis commit updates Wasmtime's platform support to no longer require anopt-in `RUSTFLAGS` `--cfg` flag to be specified. With `no_std` becomingofficially supported this should provide a better onboarding experiencewhere the fallback custom platform is used. This will cause linkererrors if the symbols aren't implemented and searching/googling shouldlead back to our docs/repo (eventually, hopefully).* Change Wasmtime's TLS state to a single pointerThis commit updates the management of TLS to rely on just a singlepointer rather than a pair of a pointer and a `bool`. Additionallymanagement of the TLS state is pushed into platform-specific modules toenable different means of managing it, namely the "custom" platform nowhas a C function required to implement TLS state for Wasmtime.* Delay conversion to `Instant` in atomic intrinsicsThe `Duration` type is available in `no_std` but the `Instant` type isnot. The intention is to only support the `threads` proposal if `std` isactive but to assist with this split push the `Duration` further intoWasmtime to avoid using a type that can't be mentioned in `no_std`.* Gate more parts of Wasmtime on the `profiling` featureMove `serde_json` to an optional dependency and gate the guest profilerentirely on the `profiling` feature.* Refactor conversion to `anyhow::Error` in `wasmtime-environ`Have a dedicated trait for consuming `self` in addition to a`Result`-friendly trait.* Gate `gimli` in Wasmtime on `addr2line`Cut down the dependency list if `addr2line` isn't enabled since thenthe dependency is not used. While here additionally lift the versionrequirement for `addr2line` up to the workspace level.* Update `bindgen!` to have `no_std`-compatible outputPull most types from Wasmtime's `__internal` module as the source oftruth.* Use an `Option` for `gc_store` instead of `OnceCell`No need for synchronization here when mutability is already available inthe necessary contexts.* Enable embedder-defined host feature detection* Add `#![no_std]` support to the `wasmtime` crateThis commit enables compiling the `runtime`, `gc`, and `component-model`features of the `wasmtime` crate on targets that do not have `std`. Thistags the crate as `#![no_std]` and then updates everything internally toimport from `core` or `alloc` and adapt for the various idioms.
