[experiment] add alternative wasm sqlite3 implementation available via build-tag (#2863)
This allows for building GoToSocial with [SQLite transpiled to WASM](https://github.com/ncruces/go-sqlite3) and accessed through [Wazero](https://wazero.io/).

# wazero: the zero dependency WebAssembly runtime for Go developers
|
||||
|
||||
[](https://github.com/tetratelabs/wazero/actions/workflows/spectest.yaml) [](https://pkg.go.dev/github.com/tetratelabs/wazero) [](https://opensource.org/licenses/Apache-2.0)
|
||||
|
||||
WebAssembly is a way to safely run code compiled in other languages. Runtimes
|
||||
execute WebAssembly Modules (Wasm), which are most often binaries with a `.wasm`
|
||||
extension.
|
||||
|
||||
wazero is a WebAssembly Core Specification [1.0][1] and [2.0][2] compliant
|
||||
runtime written in Go. It has *zero dependencies*, and doesn't rely on CGO.
|
||||
This means you can run applications in other languages and still keep cross
|
||||
compilation.
|
||||
|
||||
Import wazero and extend your Go application with code written in any language!
|
||||
|
||||
## Example
|
||||
|
||||
The best way to learn wazero is by trying one of our [examples](examples/README.md). The
|
||||
most [basic example](examples/basic) extends a Go application with an addition
|
||||
function defined in WebAssembly.
|
||||
|
||||
## Runtime
|
||||
|
||||
There are two runtime configurations supported in wazero: _Compiler_ is default:
|
||||
|
||||
By default, ex `wazero.NewRuntime(ctx)`, the Compiler is used if supported. You
|
||||
can also force the interpreter like so:
|
||||
```go
|
||||
r := wazero.NewRuntimeWithConfig(ctx, wazero.NewRuntimeConfigInterpreter())
|
||||
```
|
||||
|
||||
### Interpreter
|
||||
Interpreter is a naive interpreter-based implementation of Wasm virtual
|
||||
machine. Its implementation doesn't have any platform (GOARCH, GOOS) specific
|
||||
code, therefore _interpreter_ can be used for any compilation target available
|
||||
for Go (such as `riscv64`).
|
||||
|
||||
### Compiler
|
||||
Compiler compiles WebAssembly modules into machine code ahead of time (AOT),
|
||||
during `Runtime.CompileModule`. This means your WebAssembly functions execute
|
||||
natively at runtime. Compiler is faster than Interpreter, often by order of
|
||||
magnitude (10x) or more. This is done without host-specific dependencies.
|
||||
|
||||
### Conformance
|
||||
|
||||
Both runtimes pass WebAssembly Core [1.0][7] and [2.0][14] specification tests
|
||||
on supported platforms:
|
||||
|
||||
| Runtime | Usage | amd64 | arm64 | others |
|
||||
|:-----------:|:--------------------------------------:|:-----:|:-----:|:------:|
|
||||
| Interpreter | `wazero.NewRuntimeConfigInterpreter()` | ✅ | ✅ | ✅ |
|
||||
| Compiler | `wazero.NewRuntimeConfigCompiler()` | ✅ | ✅ | ❌ |
|
||||
|
||||
## Support Policy
|
||||
|
||||
The below support policy focuses on compatibility concerns of those embedding
|
||||
wazero into their Go applications.
|
||||
|
||||
### wazero
|
||||
|
||||
wazero's [1.0 release][15] happened in March 2023, and is [in use][16] by many
|
||||
projects and production sites.
|
||||
|
||||
We offer an API stability promise with semantic versioning. In other words, we
|
||||
promise to not break any exported function signature without incrementing the
|
||||
major version. This does not mean no innovation: New features and behaviors
|
||||
happen with a minor version increment, e.g. 1.0.11 to 1.2.0. We also fix bugs
|
||||
or change internal details with a patch version, e.g. 1.0.0 to 1.0.1.
|
||||
|
||||
You can get the latest version of wazero like this.
|
||||
```bash
|
||||
go get github.com/tetratelabs/wazero@latest
|
||||
```
|
||||
|
||||
Please give us a [star][17] if you end up using wazero!
|
||||
|
||||
### Go
|
||||
|
||||
wazero has no dependencies except Go, so the only source of conflict in your
|
||||
project's use of wazero is the Go version.
|
||||
|
||||
wazero follows the same version policy as Go's [Release Policy][10]: two
|
||||
versions. wazero will ensure these versions work and bugs are valid if there's
|
||||
an issue with a current Go version.
|
||||
|
||||
Additionally, wazero intentionally delays usage of language or standard library
|
||||
features one additional version. For example, when Go 1.29 is released, wazero
|
||||
can use language features or standard libraries added in 1.27. This is a
|
||||
convenience for embedders who have a slower version policy than Go. However,
|
||||
only supported Go versions may be used to raise support issues.
|
||||
|
||||
### Platform
|
||||
|
||||
wazero has two runtime modes: Interpreter and Compiler. The only supported operating
|
||||
systems are ones we test, but that doesn't necessarily mean other operating
|
||||
system versions won't work.
|
||||
|
||||
We currently test Linux (Ubuntu and scratch), MacOS and Windows as packaged by
|
||||
[GitHub Actions][11], as well compilation of 32-bit Linux and 64-bit FreeBSD.
|
||||
|
||||
* Interpreter
|
||||
* Linux is tested on amd64 (native) as well arm64 and riscv64 via emulation.
|
||||
* MacOS and Windows are only tested on amd64.
|
||||
* Compiler
|
||||
* Linux is tested on amd64 (native) as well arm64 via emulation.
|
||||
* MacOS and Windows are only tested on amd64.
|
||||
|
||||
wazero has no dependencies and doesn't require CGO. This means it can also be
|
||||
embedded in an application that doesn't use an operating system. This is a main
|
||||
differentiator between wazero and alternatives.
|
||||
|
||||
We verify zero dependencies by running tests in Docker's [scratch image][12].
|
||||
This approach ensures compatibility with any parent image.
