emsdk 5.0.0 #506

softmarshmallow · 2026-01-26T13:36:04Z

Emscripten dual-environment output (-sENVIRONMENT=web,node) breaks Next.js Turbopack client builds due to Node built-ins require("fs") / require("path") in generated glue emscripten-core/emscripten#26134 (fixed)

Summary by CodeRabbit

Chores
- CI workflows broadened to detect changes in nested directories, improving trigger coverage.
- Bumped canary package version, removed an obsolete prebuild patch script, and simplified packaging notes to keep Emscripten glue separate.
- Updated WebAssembly linker flags for exception/longjmp handling.
- Updated EMSDK version and its submodule pointer.
Refactor
- Native platform initialization internals reworked with no user-facing behavior changes.
Note
- No changes to public APIs or user-facing behavior.

Warning

Rate limit exceeded

@softmarshmallow has exceeded the limit for the number of commits that can be reviewed per hour. Please wait 21 minutes and 20 seconds before requesting another review.

⌛ How to resolve this issue?

After the wait time has elapsed, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

We recommend that you space out your commits to avoid hitting the rate limit.

🚦 How do rate limits work?

CodeRabbit enforces hourly rate limits for each developer per organization.

Our paid plans have higher rate limits than the trial, open-source and free plans. In all cases, we re-allow further reviews after a brief timeout.

Please see our FAQ for further information.

Walkthrough

Expanded workflow pull_request globs to recursive patterns; bumped wasm package version and removed its prebuild patch; switched native backend init to use AnySurfaceState; added Emscripten linker rustflags for wasm; removed two unused serde default helpers; updated emsdk version and submodule pointer.

Changes

Cohort / File(s)	Summary
Workflow Path Filters `\.github/workflows/build-canvas.yml`, `\.github/workflows/test-crates.yml`	Changed `pull_request` path filters from single-level globs (`.github/workflows/`, `crates/`) to recursive globs (`.github/workflows/`, `crates/`).
WASM Package & Docs `crates/grida-canvas-wasm/package.json`, `crates/grida-canvas-wasm/AGENTS.md`	Bumped package version (`0.90.0-canary.0` → `0.90.0-canary.2`); updated AGENTS.md to stop instructing patching and to externalize Emscripten glue.
Removed Prebuild Patch Script `crates/grida-canvas-wasm/scripts/prebuild-patch-emscripten-js-glue.cjs`	Deleted script that patched Emscripten JS glue to rewrite Node built-in requires.
WASM Cargo Config `crates/grida-canvas-wasm/.cargo/config.toml`	Added wasm32-unknown-emscripten rustflags: `-C link-arg=-fexceptions` and `-C link-arg=-sSUPPORT_LONGJMP=1` (with explanatory comments).
Native Backend Init `crates/grida-dev/src/platform/native_application.rs`	Replaced direct `Backend` usage with `AnySurfaceState` wrapper; obtain backend via `state.backend()` after `AnySurfaceState::from_gpu(state)`.
IO Defaults Removal `crates/grida-canvas/src/io/io_grida.rs`	Removed unused helper functions `default_locked() -> bool` and `default_z_index() -> i32`.
EMSDK Version & Submodule `bin/activate-emsdk`, `third_party/externals/emsdk`	Updated `EMSDK_VERSION` from `4.0.7` to `5.0.0`; advanced emsdk submodule pointer to new commit.

Poem

🐇 I nibbled globs and hopped the tree,

Canary climbed to two for me,
I wrapped the surface, found the backend,
Removed a patch and tweaked the link,
Tiny rabbit fixes, light and free.
