Investigation scaffolding for the Chrome-only KiCad coroutine renderer crash.
Adds isolated reproduction probes exercising the coroutine/Asyncify/fiber layer
under KiCad-like conditions, runnable in BOTH Firefox and system Chrome.
- tests/playwright-coroutine.config.ts + test:coroutine:firefox|chrome npm
scripts: run the coroutine specs in Firefox AND system Chrome (the old e2e
config only used bundled Chromium, which never reproduced the crash).
- tests/apps/standalone/coroutine-pthread/: no-wx + pthreads reproduction probes
(fiber-in-main, nested invoke_/dynCall boundaries, RunMainStack, embind,
main-loop/rAF activation) + worker_dom_stub.js for wx+pthreads builds.
- tests/apps/Makefile.wasm: coroutine-pthread{,-main,-nested,-nested-ex,-wx,
-embind,-mainloop} targets.
- scripts/common/shims/diagnostics.js: add EM_ASYNC_JS handleSleep enter/wake
tracking (DIAG_SLEEP) to detect nested-async at the crash.
Findings (details in research notes): every isolated factor so far — direct /
nested / RunMainStack fiber, wx event loop + all 13 scenarios incl EM_ASYNC_JS,
pthreads, and main-loop/rAF activation — runs CLEAN in system Chrome. The
coroutine/Asyncify layer is exonerated; GL/WebGL is the remaining untested factor
(next). The reliable FF-pass/Chrome-fail repro is still the KiCad pcbnew e2e.

The shim bound bare dynCall_* names to JS getWasmTableEntry() calls, bypassing
the asyncify-instrumented dynCall_* wasm trampolines that -sDYNCALLS=1 provides.
That broke Asyncify unwind/rewind through indirect calls -> "indirect call
signature mismatch" (caught every frame in Firefox; fatal renderer crash in
Chrome). Bind the bare names to wasmExports["dynCall_<sig>"] instead.
Result: the PCBnew "select draw lines" e2e is green in Firefox (tool selects and
draws, zero page errors). Dropped the fiber-stabilization block, the shipped
diagnostic block, and the exportCallStack JS hack (all compensated for the wrong
binding); shim shrank 521 -> ~250 lines.
- scripts/common/inject-dyncall-shims.sh: orchestrator only; injected JS extracted
to scripts/common/shims/
- scripts/common/shims/dyncall-binding.js.tmpl: per-signature binding template
- scripts/common/shims/handlesleep.js: nested-Asyncify handleSleep fix (#9153)
- scripts/common/shims/diagnostics.js: logging-only, opt-in via SHIM_DIAGNOSTICS=1
- tests/package.json: add test:kicad:firefox / test:kicad:chrome scripts
Known issue (tracked separately): Chrome still renderer-crashes on the first
coroutine resume. Asyncify.doRewind replays the deep main-context call stack and
exceeds V8's execution-stack limit (Firefox tolerates the same wasm). Proper fix
is JSPI.

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.

wxwidgets: bb80f91e8b (wip: wxAuiToolBar element-registry registration +

## 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.

The Docker build used emscripten/emsdk:4.0.2-arm64 as base image but
env.sh couldn't find emsdk there, installing a second copy. The build
then applied wasm-opt/finalize stubs to the wrong emsdk (hardcoded
/emsdk/), so the real wasm-emscripten-finalize ran in Docker and got
OOM-killed.
- Use ubuntu:22.04 base with emsdk installed from source at /emsdk/
- Make stub paths dynamic via $EMSDK instead of hardcoded /emsdk/
- Skip local emsdk install in env.sh when $EMSDK is already active

Emscripten 4.x removed dynCall_* WASM exports, breaking asyncify
rewind through indirect calls (modal dialogs, event handlers).
Generate JS shims that track Asyncify.exportCallStack and register
in wasmExports so doRewind can find them.
Also fixes empty callback functions ((() => {})) generated by
Emscripten 4.x + pthreads for HTML5 events, pthread entry,
sighandler, async timer, and main loop callbacks.
Build pipeline improvements:
- Stub wasm-opt/finalize in Docker (RAM limits), run on host
- Add setup-emsdk.sh for reproducible Emscripten setup
- Simplify env.sh and version management
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Emscripten with pthreads generates empty arrow functions `{}` for callback
paths it assumes won't be used. However, when registering HTML5 events from
the main browser thread, targetThread is 0 and the direct call path IS taken.
This fix post-processes the generated JS to replace empty callbacks with
actual dynCall invocations for:
- HTML5 event callbacks (dynCall_iiii) - 7 instances
- pthread entry points (dynCall_ii) - 1 instance
- Signal handlers (dynCall_vi) - 1 instance
- Async timers (dynCall_vi) - 1 instance
Also improves build logging to show completion status and exit code.

2. test-gal-regression.sh: Remove "skip if already built" check
- Always rebuild to pick up code changes
- Single script is the source of truth for full test cycle
Current results:
- 3 scenarios MATCH (<1%): basic-lines, arcs, transforms

- Wait for isReady() not just module existence
- Use .gl-canvas selector (same as individual tests)
- Increase timeout from 50ms to 100ms
- This fixes blank screenshots in full test runs
2. Fix test-gal-regression.sh comparison:
- Normalize PNG format before comparing (flatten + sRGB TrueColor)
- This handles RGBA vs RGB and palette differences
- gal-basic-lines now passes comparison (0.34% different)
Results after fixes:
- Native vs Baseline: PASSED (28/28)
- WebGL screenshots now capture actual rendered content
- gal-basic-lines matches native (first successful scenario!)
- Other scenarios have rendering differences to investigate

Major refactoring to remove ALL legacy OpenGL immediate mode calls from
WEBGL_GAL and replace them with WebGL 2.0/OpenGL ES 3.0 compatible code.
Key changes:
- Add MVP matrix uniform support (replaces glMatrixMode/glOrtho/glLoadMatrix)
- Add matrix math helpers (computeOrthoMatrix, multiplyMatrix4x4, etc.)
- Replace glBegin/glEnd/glVertex with vertex manager pattern
- Rewrite DrawCursor to use vertex manager and DrawLine() calls
- Rewrite DrawBitmap to use vertex manager with SHADER_FONT mode
- Replace glEnableClientState with glVertexAttribPointer
- Replace glDrawBuffer with glDrawBuffers (WebGL 2.0 API)
- Add fullscreen_quad.cpp/h for compositor Present()
- Update SHADER class with mat4 uniform support
- Add MultiplyMatrix() to vertex_manager for Transform()
- Remove all legacy GL stubs from wasm_stubs.cpp
Build now completes with FULL_ES3 mode (no LEGACY_GL_EMULATION).
Remaining issue: wxWidgets GL library calls glColor3f internally.

Add complete test infrastructure for WebGL GAL visual regression testing:
- scripts/test-gal-regression.sh: Master script that builds both backends,
runs tests, and performs two-level comparison (native vs baseline,
webgl vs native)
- scripts/build-gal-webgl-test.sh: WASM build using Makefile with em++
- tests/gal-regression/wasm/: WebGL test harness (stub WEBGL_GAL)
- tests/e2e/gal-webgl.spec.ts: Playwright test for screenshot capture
Fix Homebrew Emscripten environment in scripts/common/env.sh:
- Set EMSDK_PYTHON for Python 3.10+ (em++ reads this, not $PYTHON)
- Add bundled LLVM to PATH (Emscripten needs its clang with WASM backend)
Verified: Native vs Baseline passes (28/28), WebGL generates blank
screenshots as expected (WEBGL_GAL implementation is Phase 2).

Add a standalone test application that compiles KiCad's actual OPENGL_GAL
against system wxWidgets to generate baseline screenshots for comparing
native OpenGL rendering against WebGL rendering in the browser.
Architecture:
- Compiles 18 KiCad GAL source files from the kicad submodule
- Uses template-based private member accessor (safer than #define private public)
- Generates shader C++ files from GLSL (10 shader pairs for SMAA AA)
- Minimal stubs for KiCad dependencies (PGM_BASE, ADVANCED_CFG, etc.)
Test coverage:
- 11 scenarios testing ~19% of GAL API
- basic-lines, line-widths, circles, arcs, rectangles, polygons
- alpha-blending, transforms, grid-cursor, segments, complex-scene
Key insights documented:
- GAL uses world-to-screen transformation requiring 1:1 pixel mapping
- FBO reading required for clean screenshots on macOS
- Layer depth needed for proper z-ordering in complex scenes
