From abac88be1480602f1aa3072371d5ecf377c6ba02 Mon Sep 17 00:00:00 2001 From: Krzysztof Rodak Date: Tue, 21 Jul 2026 18:55:48 +0200 Subject: [PATCH] feat: Enable WebAssembly compilation Add wasm (wasm32-unknown-wasip1) support in Package@swift-5.9.swift: depend on upstream apple/swift-nio plus the standalone PassiveLogic/nio-async-runtime, and consume the wasm-safe PassiveLogic sqlite-nio and async-kit forks (pinned to the same version ranges as upstream, resolved once those forks are tagged). Import NIOAsyncRuntime's NIOThreadPool on wasi and NIOPosix elsewhere, gated on os(WASI). NIOPosix is gated to non-wasi; non-wasm builds are unchanged.
