c3a6060b - Polyfill `ToWasmtimeResult` and add eventually-necessary call sites (#12308)

Tue, 13 Jan 2026 18:04:34 +0000

Polyfill `ToWasmtimeResult` and add eventually-necessary call sites (#12308)* Polyfill `ToWasmtimeResult` and add eventually-necessary call sitesThis commit polyfills `wasmtime_internal_error::ToWasmtimeResult` in`wasmtime_environ`, adds the cargo feature plumbing that will eventually connectto the `"wasmtime_internal_error/anyhow"` cargo feature but for now justconfigures this polyfill, and adds uses of the polyfill at all the sites thatwill be necessary once we swap out `anyhow` for`wasmtime_internal_error`. Currently, the polyfill is just an identity function,because `wasmtime::Result`/`wasmtime_environ::error::Result` is just anothername for `anyhow::Result`. Once we do move away from `anyhow`, however, thatwill no longer be the case, and these uses will do the necessary conversion.My goal with landing this as an incremental commit is to make it so that theactual commit that does the error crate swap out can be as close to _just_ the`Cargo.toml` dependency change, without any other code changes as much aspossible. This, in turn, means that swap out should be super easy to revert, ifnecessary.* Add a couple more `.to_wasmtime_result()` invocations in fuzz code* Revert "Add a couple more `.to_wasmtime_result()` invocations in fuzz code"This reverts commit b33696e5f63f7eed731ca9dad10fec5e55a550d3.* Move cranelift fuzz targets back to anyhow* Fix cargo feature enablement for explorer List of files: /wasmtime-44.0.1/crates/explorer/src/lib.rs

4c8edb95 - More clearly flag internal crates as such (#10963)

Fri, 06 Jun 2025 21:13:36 +0000

More clearly flag internal crates as such (#10963)* More clearly flag internal crates as suchThis commit is an attempt to more clearly flag internal crates in thisproject as internal and not intended for external use. Specifically:* Many crates are renamed from `wasmtime-foo` to `wasmtime-internal-foo`.* All of these crates now have `INTERNAL: ...` in their crates.io description.* All of these crates now have a warning at the top of their documentation discouraging use.This change is a result of rustsec/advisory-db#1999 where the goal is tobe crystal clear from a project perspective that usage of these cratesare highly discouraged and not supported. We'll still probably get suchadvisories but we won't be considering them CVEs from the project itselfdue to the internal nature of these crates and the discouragingwarnings.Some concrete changes used here are:* Inter-crate dependencies still use `wasmtime_foo` for naming and do so with Cargo's package-renaming features.* Crate renames are specified at the workspace level so the rename is only in one locations and all other inherit it.* Contribution documentation now has some brief guidelines about crate organization.* Update vet config* Update checks for wasmtime-fiberprtest:full* Update publish script* Another fiber rename* Fix some doc tests List of files: /wasmtime-44.0.1/crates/explorer/src/lib.rs

9ec02f9d - Decouple `serde` from its `derive` crate (#6917)

Tue, 29 Aug 2023 16:02:06 +0000

Decouple `serde` from its `derive` crate (#6917)By not activating the `derive` feature on `serde`, the compilation speedcan be improved by a lot. This is because `serde` can then compile inparallel to `serde_derive`, allowing it to finish compilation possiblyeven before `serde_derive`, unblocking all the crates waiting for`serde` to start compiling much sooner.As it turns out the main deciding factor for how long the compile time of aproject is, is primarly determined by the depth of dependencies ratherthan the width. In other words, a crate's compile times aren't affectedby how many crates it depends on, but rather by the longest chain ofdependencies that it needs to wait on. In many cases `serde` is part ofthat long chain, as it is part of a long chain if the `derive` featureis active:`proc-macro2` compile build script > `proc-macro2` run build script >`proc-macro2` > `quote` > `syn` > `serde_derive` > `serde` >`serde_json` (or any crate that depends on serde)By decoupling it from `serde_derive`, the chain is shortened and compiletimes get much better.Check this issue for a deeper elaboration:https://github.com/serde-rs/serde/issues/2584For `wasmtime` I'm seeing a reduction from 24.75s to 22.45s whencompiling in `release` mode. This is because wasmtime through `gimli`has a dependency on `indexmap` which can only start compiling when`serde` is finished, which you want to happen as early as possible sosome of wasmtime's dependencies can start compiling.To measure the full effect, the dependencies can't by themselvesactivate the `derive` feature. I've upstreamed a patch for`fxprof-processed-profile` which was the only dependency that activatedit for `wasmtime` (not yet published to crates.io). `wasmtime-cli` andco. may need patches for their dependencies to see a similarimprovement.

af7ef8df - Fix some minor issues with the `explorer` command (#5988)

Sat, 11 Mar 2023 02:31:31 +0000

Fix some minor issues with the `explorer` command (#5988)This commit fixes a few minor issues that Nick and I ran into walkingthrough some code with the `wasmtime explore` command:* When a new function is reached the address map iterator is advanced past the prior function to avoid accidentally attributing instructions across functions.* A `<` comparison was changed to `<=` to fix some off-by-one attributions from instructions to wasm instructions.* The `skipdata` option is enabled in Capstone to avoid truncating AArch64 disassemblies too early.

9ed441e6 - Introduce the `wasmtime-explorer` crate (#5975)

Sat, 11 Mar 2023 00:33:06 +0000

Introduce the `wasmtime-explorer` crate (#5975)This implements Godbolt Compiler Explorer-like functionality for Wasmtime andCranelift. Given a Wasm module, it compiles the module to native code and thenwrites a standalone HTML file that gives a split pane view between the WAT andASM disassemblies.
