In practice stdlib already provides `std.Io.Threaded.global_single_threaded` for exactly this scenario: > In some cases such as debugging, it is desirable to hardcode a > reference to this `Io` implementation. It's a single process-wide instance, and — importantly — the only ops this example uses (`Timestamp.now`, `random`, etc.) bottom out in OS calls that don't touch the `Threaded` struct's internal mutable state, so one shared instance is safe for this use case. This removes the `threadlocal var` declaration entirely, matching the stdlib-recommended pattern for examples. --- examples/hello_world/mod.zig | 9 ++++----- 1 file changed, 4 insertions(+), 5 deletions(-) diff --git a/examples/hello_world/mod.zig b/examples/hello_world/mod.zig index bbb91ab..5128049 100644 --- a/examples/hello_world/mod.zig +++ b/examples/hello_world/mod.zig @@ -4,12 +4,11 @@ const Io = std.Io; const zapi = @import("zapi"); const allocator = std.heap.page_allocator; -/// Thread-local single-threaded Io instance — each thread gets its own copy, -/// so `init_single_threaded` is safe (no cross-thread sharing). -threadlocal var threaded: Io.Threaded = .init_single_threaded; - +/// Process-wide single-threaded `Io` instance. stdlib exposes this as +/// `std.Io.Threaded.global_single_threaded` specifically for examples and +/// debugging — library code should accept an `Io` parameter instead. fn io() Io { - return threaded.io(); + return Io.Threaded.global_single_threaded.io(); } comptime { From 76dae721fee2e64be8367258b076ff662ed133a1 Mon Sep 17 00:00:00 2001 From: Chen Kai Date: Mon, 20 Apr 2026 22:10:57 +0800 Subject: [PATCH 14/17] chore: port main's newly-merged code to Zig 0.16 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The merge with main brought in the js_dsl feature (#11) and a refactor of `src/root.zig` (napi symbols moved to `src/napi.zig`, re-exported via `pub usingnamespace`). All of that was written for 0.14.1 and hits several 0.16 breaking changes: * `b.modules.put(key, value)` → `b.modules.put(allocator, key, value)`. Two call sites in `build.zig` were missed by the previous update pass (the `napi` module and the `example_js_dsl` module). * `src/napi.zig` exported `pub const c = @import("c.zig")`, but every internal file accesses napi types through the inner `.c` namespace. Restore the `.c` on the import. * `pub usingnamespace` was removed in Zig 0.16. Replace it in `src/root.zig` with explicit `pub const foo = napi.foo;` re-exports. * `callconv(.C)` → `callconv(.c)` (6 NAPI callback shims in `src/js/wrap_class.zig` and `src/js/wrap_function.zig`). * `std.Thread.Mutex` → `std.Io.Mutex`. The DSL's per-class registry in `src/js/class_runtime.zig` needs a 0.16-compatible mutex, which requires an `Io`. The `Io` is threaded in through the DSL's entry point rather than letting zapi carry global state: - `js.exportModule` gains an optional `.io = fn () std.Io` field in `options`. The generated `moduleInit` calls it after the user's `options.init` hook and passes the result down into `registerDecls` → `class_runtime.registerClass`. If `.io` is omitted, a DSL-local `init_single_threaded` fallback keeps zero-config modules compiling. - `registerClass` caches the resolved `Io` in per-`T` `state(T).io`; `getConstructor`, `materializeClassInstance`, and `cleanupHook` all read from this cache because they execute inside napi C callbacks that can't receive user-provided `Io`. - Normal paths (`registerClass`, `getConstructor`) use cancelable `try mutex.lock(io)` so caller cancellation can propagate. - `cleanupHook` (a napi C callback with a fixed `(*Entry)` signature that cannot return errors) uses `lockUncancelable` deliberately — unwinding on cancel would leak the entry and hand napi a dangling pointer. * `Env` gains a `fromRaw(raw_env)` constructor so the 19 napi C callback sites don't all hand-roll the `Env{ .env = ... }` literal. `Env` itself stays a pure `napi_env` wrapper — no `io` field. After this commit `zig build` succeeds, and `zig build test` runs the 42 regular tests green. `example_js_dsl` has a separate, pre-existing link issue in `zig build test` (undefined `_napi_wrap` and friends, resolved by Node at runtime when loading the `.node` file) — orthogonal to the 0.16 migration. --- build.zig | 14 ++++++++++++-- examples/hello_world/mod.zig | 3 --- examples/js_dsl/mod.zig | 8 ++++++++ src/js/class_runtime.zig | 23 +++++++++++++++-------- src/js/export_module.zig | 24 +++++++++++++++++++----- src/js/wrap_class.zig | 10 +++++----- src/js/wrap_function.zig | 2 +- src/module.zig | 4 +--- src/napi.zig | 2 +- src/root.zig | 26 +++++++++++++++++++++++--- 10 files changed, 85 insertions(+), 31 deletions(-) diff --git a/build.zig b/build.zig index aaf0ee1..2679ccc 100644 --- a/build.zig +++ b/build.zig @@ -17,7 +17,7 @@ pub fn build(b: *std.Build) void { .optimize = optimize, }); module_napi.addIncludePath(b.path("include")); - b.modules.put(b.dupe("napi"), module_napi) catch @panic("OOM"); + b.modules.put(b.allocator, b.dupe("napi"), module_napi) catch @panic("OOM"); const module_zapi = b.createModule(.{ .root_source_file = b.path("src/root.zig"), @@ -80,7 +80,7 @@ pub fn build(b: *std.Build) void { .optimize = optimize, .link_libc = true, }); - b.modules.put(b.dupe("example_js_dsl"), module_example_js_dsl) catch @panic("OOM"); + b.modules.put(b.allocator, b.dupe("example_js_dsl"), module_example_js_dsl) catch @panic("OOM"); const lib_example_js_dsl = b.addLibrary(.{ .name = "example_js_dsl", @@ -132,6 +132,12 @@ pub fn build(b: *std.Build) void { .root_module = module_example_hello_world, .filters = b.option([][]const u8, "example_hello_world.filters", "example_hello_world test filters") orelse &[_][]const u8{}, }); + // Napi C symbols (`napi_wrap`, `napi_typeof`, …) are resolved at + // runtime by Node when it loads the `.node` file.

zbuild materializes them at build time. - All build steps from the previous build.zig are preserved (`build-lib:*`, `test:*`, `build-test:*`, `test`).
