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.

b63c25ae - fix(no_std)!: respect `std` feature when target is windows/unix (#11152)

Thu, 03 Jul 2025 22:07:42 +0000

fix(no_std)!: respect `std` feature when target is windows/unix (#11152)* fix(no_std)!: respect `std` feature when target is windows/unixBREAKING CHANGE: the fix disables standard features for dependents that use wasmtime with `default-features = false`.* fix cargo check workflow* Don't require `std` feature for invalid faultsFill out the `compile_error!` to avoid failing a build.* addressing review comments* add `std` to `stack-switching` feature* remove `rustix/mm` from `std` feature dependencies* add `std` feature flag to `jit-icache-coherence`- The `std` feature gates the use of standard library for icache coherence in Windows; otherwise, defaults to the `libc` implementation.- The `std` feature of Wasmtime now depends on the `wasmtime-jit-icache-coherence/std`* Only include jit-icache-coherence on `std` buildsprtest:full* Fix some idiom issues* More idiom issues* Require `std` for loading native code---------Co-authored-by: Alex Crichton List of files: /wasmtime-44.0.1/crates/wasmtime/src/runtime/vm/sys/mod.rs

d88aeda8 - Increase alignment of empty mmap pointers (#9393)

Tue, 08 Oct 2024 15:31:51 +0000

Increase alignment of empty mmap pointers (#9393)This commit updates platform implementations of `Mmap::new_empty()` touse a shared helper to create a pointer with a higher alignment thanone. This fixes a debug assert tripping in niche configurations of thepooling allocator where if no virtual memory is given and table lazyinit is disabled then a module could trip a debug-only assert about aslice being created from a raw pointer that is not properly aligned. Thefix here is to use a helper that starts with an over-aligned empty slicewhich is then casted down to a byte slice. List of files: /wasmtime-44.0.1/crates/wasmtime/src/runtime/vm/sys/mod.rs

aa2beaee - Handle all `decommit`s/`madvise(DONTNEED)`s homogenously (#8587)

Thu, 09 May 2024 01:06:08 +0000

Handle all `decommit`s/`madvise(DONTNEED)`s homogenously (#8587)* Don't differentiate between decommitting table vs stack pagesAll implementations are the same either way, and by treating them differently,it makes it difficult to prototype integration with batching syscalls that needto treat them homogenously.Co-Authored-By: Jamey Sharp * Remove the `madvise_dontneed` function from the system virtual memory interfaceThis was already implemented by the existing `decommit_pages` function, we justneed to determine what the behavior is for the left over mapping. Specifically,whether it is zeroed or restored to the original mapping (e.g. a CoW image).This allows us to handle `decommit_pages` and what previously were calls to`madvise_dontneed` homogenously, which enables us to prototype new system callsthat batch decommits together and therefore must treat them all the same.Co-Authored-By: Jamey Sharp ---------Co-authored-by: Jamey Sharp List of files: /wasmtime-44.0.1/crates/wasmtime/src/runtime/vm/sys/mod.rs

81a89169 - Add support for `#![no_std]` to the `wasmtime` crate (#8533)

Sat, 04 May 2024 22:02:26 +0000

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. Thisended up requiring some relatively extensive changes, but nothing tootoo bad in the grand scheme of things.* Require `std` for the perfmap profiling agentprtest:full* Fix build on wasm* Fix windows build* Remove unused import* Fix Windows/Unix build without `std` feature* Fix some doc links* Remove unused import* Fix build of wasi-common in isolation* Fix no_std build on macos* Re-fix build* Fix standalone build of wasmtime-cli-flags* Resolve a merge conflict* Review comments* Remove unused import List of files: /wasmtime-44.0.1/crates/wasmtime/src/runtime/vm/sys/mod.rs
