Main-repo side of a multi-part WIP covering the KiCad WASM tool-selection
and nested-Asyncify work. Submodule commits are in kicad@f6e9239aaa
(libcontext hygiene) and wxwidgets@bb80f91e8b (auibar registration +
dialog diagnostics).
## scripts/common/inject-dyncall-shims.sh
Wrap Asyncify.handleSleep / allocateData to save-and-restore Asyncify.currData
around each EM_ASYNC_JS sleep. This fixes the nested Asyncify collision where
a fiber swap that fired during a modal's event loop clobbered currData, and
the modal's later doRewind used the fiber's buffer and hit "RuntimeError:
index out of bounds". Root cause documented as Emscripten Issue #9153
(wontfix upstream).
Diagnostic-rewind logging (forcedBottomOfCallStack, callStack traces) is
retained to help future debugging of Asyncify state corruption.
## tests/
- tests/playwright-kicad.config.ts: add `channel: 'chrome'` for the
chromium project so --project=chromium --headed uses system Chrome
(real GPU) instead of SwiftShader on ARM Mac. Also switch trace to
retain-on-failure + screenshot on-failure for easier E2E debugging.
- tests/kicad/pcbnew.spec.ts: replace `tool.checked` assertions with a
label-suffix check (`[checked]`) since our auibar registration encodes
checked state in the label (no schema change to the registry).
- tests/apps/Makefile.wasm: add `coroutine-nested` build target + include
it in the all: list.
- tests/apps/standalone/coroutine/: kicad_coroutine_harness.h + test app
reproducing KiCad COROUTINE semantics against real libcontext.
- tests/apps/standalone/coroutine-nested/: nested_test.cpp reproduces the
EM_ASYNC_JS-modal + fiber-swap nesting bug in isolation. 8 scenarios
from baseline_modal_alone through nested_fibers_inside_modal.
- tests/e2e/coroutine.spec.ts + coroutine-nested.spec.ts: Playwright specs
that load the standalone apps and assert all case cases pass via
[COROUTINE_TEST] SUMMARY log parsing.
## research/ and features/browser-tools/
Three background docs capturing the investigation trajectory:
- features/browser-tools/0001-kicad-wasm-tool-activation-investigation.md
Early investigation: why tools don't activate; initial dynCall-empty-
callback hypothesis.
- features/browser-tools/0002-wasm-coroutine-deep-dive.md
Deep dive on Asyncify internals, fiber API, QEMU's coroutine-wasm
reference implementation.
- features/browser-tools/0003-wxauitoolbar-registration-fix.md
The narrow fix: why wxAuiToolBar needs a registration block, where to
add it, what the fallback plan is.
- research/threading_1.md: corrected root-cause analysis after reading
runtime logs — nested-Asyncify currData collision, Emscripten #9153.
- research/threading_2.md: extended research on alternative approaches
(JSPI/WasmFX/state-machines) and why they don't help here.
## Submodule pointer updates
kicad: f6e9239aaa (wip: libcontext WASM hygiene cleanup)
wxwidgets: bb80f91e8b (wip: wxAuiToolBar element-registry registration +
dialog diagnostics)
## Open threads not yet in scope
- Firefox/Chrome divergent behavior: "indirect call signature mismatch"
traps in Firefox vs renderer crash in system Chrome (tracked in
plans/peaceful-hugging-pnueli.md and the research docs).
- E2E pixel-diff for Draw Lines fails because the test's diff region does
not cover where the line is actually drawn; tool activation works, the
line is visible in test-results/pcbnew-draw-lines-02-after-drawing.png.

Chrome headless crashes on ARM Mac due to a known Chromium bug where
SwiftShader WebGL is disabled on ARM architecture (issues #1416283,
#338414704). Firefox headless works reliably using native Metal.
Changes:
- Use Firefox as default for npm run test:kicad (headless)
- Use Chrome with --headed flag for npm run test:kicad:headed
- Add viewport size and increase timeout for KiCad WASM
- Simplify pcbnew.spec.ts test assertions

- wxWidgets logs: tests/logs/wxwidgets/<test-file>/
- KiCad logs: tests/logs/kicad/<test-file>/
- Global setup now cleans all log subdirectories recursively
- Added globalSetup to KiCad playwright config

- npm run test:kicad now auto-runs setup script first
- Create separate playwright-kicad.config.ts for KiCad tests
- Fix kicad spec to use web server instead of file:// paths
- Remove duplicate pcbnew.html/wasm from tests/kicad/
(proper files are in tests/apps/kicad/)
Test separation:
- npm test: runs only wxWidgets tests (tests/e2e/)
- npm run test:kicad: runs only KiCad tests (tests/kicad/)
