Release notes

v1.7.0

Welcome to wazero 1.7: the release that upgrades like a minor, but feels like a major!

It's finally time for the long-awaited, final release of our brand new optimizing compiler. This is such a big deal that we are celebrating it at [Wasm I/O 2024][wasmio] with another round of wonderful lightning talks from wazero users [like we did in 2023][wazero1]. In fact, even this release is being tagged during the event! Stay tuned on our usual channels to see the recording:

wazero optimizes machine code compiled from wasm

Translating Wasm bytecode into machine code can take multiple forms. An optimizing compiler performs multiple nontrivial transformations on the input code, ultimately producing more efficient ("optimized") code.

In 1.7 we replaced our internal wasm compiler with an optimizing one. This means it is a drop-in: you don’t need to do anything to use it. If interested in compiler design, please read [the docs][wazevo-docs], contributed by @​evacchi.

As for performance improvements, we have come to expect a run-time boost ranging from 10% to even 60%, with 30-40% being the average. Notably:

• @​ncruces' fork of [coremark][coremark] shows an improved score of 15265 vs 9591, i.e. about +60% on arm64 (Apple M1 Pro)
• [mercari/grpc-federation][mercari] improvements between 4-10% on their Wasm extensions to the [Common Extension Language][cel]
• [kubernetes-sigs/kube-scheduler-wasm-extension][k8s-sched] sees an average of >40% decrease on schedule lifecycle overhead
• @​achille-roussel [contributed some numbers][achille-slack] on the Go standard library (GOOS=wasip1) showing at least 30% improvements on the syscall, compress/flate (gzip) and encoding/json packages, with peaks of 60% (especially in data throughput).

While a major improvement, we decided against calling this version 2.0. If we did, we would cause library dependency lockups due to go imports needing a ‘/v2’. We take backwards compatibility seriously, so couldn’t do that to you!

As usual, @​mathetake owns the lionshare of the contributions, with @​evacchi helping along the way, especially on the new amd64 backend. Notably, @​achille-roussel also contributed a performance improvement to the compiler (#2026) and @​ncruces helped in many ways with testing and verifying the implementation, validating (among other things) against his library [go-sqlite3][go-sqlite3].

Note: an optimizing compiler does more work, so it takes longer. Production use of wazero should always compile wasm during initialization to avoid slowing down function runtime.

Experimental: Wasm Threads Spec

The Wasm Threads spec introduces instructions to explicitly share memory between modules, and new operations for atomic memory access. Compilers may use this feature for concurrent threads of execution. For instance @​anuraaga’s [Go ports of protoc plugins][protoc] needed atomic instruction support to compile to Wasm.

1.7 concludes a long journey started with @​anuraaga's first PR #1899 and continued with @​mathetake occasionally tag-teaming, especially to support in the new compiler; @​ncruces assisted with reviewing.

You can enable Wasm Threads support by setting the corresponding flag:

     // Threads support must be enabled explicitly in addition to standard V2 features.
     cfg := wazero.NewRuntimeConfig().
           WithCoreFeatures(api.CoreFeaturesV2 | experimental.CoreFeaturesThreads)

For a usage example see features_example_test.go

Experimental: Snapshot/Restore

The Snapshot/Restore experimental feature saves the state of a wasm function and restores it later. This feature has been contributed by @​anuraaga to implement exception handling in [wasilibs/go-pgquery][go-pgquery]

You can enable snapshot/restore by setting the context flag:
