96e19700 - Migrate the `wasmtime` crate to `wasmtime_environ::error::*` (#12231)

Wed, 07 Jan 2026 17:08:11 +0000

Migrate the `wasmtime` crate to `wasmtime_environ::error::*` (#12231)* Migrate the `wasmtime` crate to `wasmtime_environ::error::*`Instead of `anyhow::Error`.This commit re-exports the `wasmtime_environ::error` as the `wasmtime::error`module, updates the prelude to include these new error-handling types, redirectsour top-level `wasmtime::{Error, Result}` re-exports to re-export`wasmtime::error::{Error, Result}`, and updates various use sites that weredirectly using `anyhow` to use the new `wasmtime` versions.This process also required updating the component macro and wit-bindgen macro touse the new error types instead of `anyhow`.Part of https://github.com/bytecodealliance/wasmtime/issues/12069* Replace wasmtime::error::Thing with wasmtime::Thing where it makes sense* cargo fmt* Move `crate::error::Thing` to `crate::Thing` where it makes sense List of files: /wasmtime-44.0.1/crates/wasmtime/src/runtime/vm/stack_switching/stack.rs

35786823 - Deny `unsafe_op_in_unsafe_fn` in `wasmtime::runtime::vm` (#11312)

Deny `unsafe_op_in_unsafe_fn` in `wasmtime::runtime::vm` (#11312)* Deny `unsafe_op_in_unsafe_fn` in `wasmtime::runtime::vm`Slowly expanding this lint to more of the crate.prtest:full* Fix lints in custom module* Fix some lints with miri* Fix non-VM build* Fix arm windows List of files: /wasmtime-44.0.1/crates/wasmtime/src/runtime/vm/stack_switching/stack.rs

838ed2d0 - Enable `allow_attributes_without_reason` (#11195)

Mon, 07 Jul 2025 21:52:03 +0000

Enable `allow_attributes_without_reason` (#11195)* Enable `allow_attributes_without_reason`This commit enables the `clippy::allow_attributes_without_reason` forthe `wasmtime` crate which previously forcibly allowed it. 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.

63d482c8 - Stack switching: Infrastructure and runtime support (#10388)

Stack switching: Infrastructure and runtime support (#10388)* [pr1] base* prtest:full* make sure to use ControlFlow result in trace_suspended_continuation* stack-switching: cleanup: remove stray c-api changesThese are remnants of unrelated wasmfx wasmtime experiments, possiblysuitable for later submission against upstream.* stack-switching: reuse async_stack_size* stack-switching: delete delete_me debugging* stack-switching: address feedback in environ::types* stack-switching: remove unused code from vmoffsets* stack-switching: drop dependency on std* stack-switching: add compilation checks to ci matrix* stack-switching: remove debug_println cruft* stack-switching: export environ consts consistently* stack-switching: export vm pub items consistently* table_pool: reduced capacity for large elementsVMContRef elements which takes up two words and we don't want todouble the size of all tables in order to support storing these.This change changes the table to target storing the requestedmax number of elements if they are "nominally" sized with(potentially) reduced capacity for non-nominally sized types whenencountered.Continuations are the only type of element which may result infewer table slots being available than requested.* stack-switching: extend conditional compilationA fair bit of the definitions for stack switching are stillenabled, but this patch takes things a bit further to avoidcompilation problems; notably, cont_new is now not compiledin unless the feature is enabled.* stack-switching: formatting fixes* stack-switching: address new clippy checksIn addition, to get clippy to fully pass, plumbed inadditional config to make winch paths happy; there's noimpl for winch yet but plumbing through the feature isrequired to make paths incorporating macros at variouslayers satisfied (and it is expected we'll use thefeatures in the future).* stack-switching: more conditional compilation fixes* stack-switching: additional conditional compile on table builtins for continuations* stack-switching: additional conditional compile fixes* stack-switching: additional conditional compile in store* stack-switching: remove overly strict assertion* stack-switching: remove errantly dropped no_mangle in config c-api* stack-switching: VMContObj::from_raw_parts* stack-switching: remove duplicate async_stack_size feature check* stack-switching: VMArray -> VMHostArray* stack-switching: remove unnecessary clippy exception* stack-switching: fix docs referenced VMRuntimeLimits* stack-switching: fix doc typo* stack-switching: follow recommendations for type casts* stack-switching: use usize::next_multiple_of* stack-switching: update outdated comment* stack-switching: use feature gate instead of allow(dead_code)* stack-switching: rework backtrace using chunks/zip* stack-switching: move tests to footer moduleThis is a bit more consistent with the prevailing stylein tree and (subjectively) makes finding the testsas a reader more straightforward.Tests left unchanged sans some import cleanup.* stack-swictchding: verify stack_chain offsets at runtime* fixup! stack-switching: use feature gate instead of allow(dead_code)* stack-switching: document continuation roots tracing using match arms---------Co-authored-by: Paul Osborne List of files: /wasmtime-44.0.1/crates/wasmtime/src/runtime/vm/stack_switching/stack.rs
