From db2f5e18e95175cfd732b3ddac4e0b973077eab1 Mon Sep 17 00:00:00 2001 From: andodeki Date: Sun, 16 Aug 2026 14:36:10 +0300 Subject: [PATCH 01/53] feat(test): Android makepad_test via adb + in-process hub (legacy Java path) Adds the Android test runtime to makepad_test: builds the APK with cargo-makepad's standard Java path, installs and launches via adb with makepad.STUDIO_* intent extras (incl. STUDIO_BUILD), connects the app to an in-process hub over adb reverse, and waits for startup + responsiveness. Adds clean in-process hub shutdown (HttpServerHandle + GatewayHandle Drop) and the STUDIO_BUILD intent parsing on the app side. No native-activity or NDK APK compilation code is included. --- examples/counter/src/main.rs | 23 +- libs/makepad_test/src/runtime.rs | 367 ++++++++++++++++++- platform/network/src/http_server.rs | 45 ++- platform/network/src/lib.rs | 2 +- platform/network/src/runtime.rs | 4 +- platform/src/os/linux/android/android_jni.rs | 12 + studio/hub/Cargo.toml | 4 + studio/hub/src/bin/hub_server.rs | 38 ++ studio/hub/src/gateway.rs | 30 +- tools/web_server/src/main.rs | 2 +- 10 files changed, 492 insertions(+), 35 deletions(-) create mode 100644 studio/hub/src/bin/hub_server.rs diff --git a/examples/counter/src/main.rs b/examples/counter/src/main.rs index 1e63fa5d5..449f5b598 100644 --- a/examples/counter/src/main.rs +++ b/examples/counter/src/main.rs @@ -6,15 +6,8 @@ app_main!(App); script_mod! { use mod.prelude.widgets.* - let state = { - counter: 0 - } - mod.state = state startup() do #(App::script_component(vm)){ ui: Root{ - on_startup:||{ // right now render isnt called automatically yet - ui.main_view.render() - } main_window := Window{ window.inner_size: vec2(420, 220) body +: { @@ -24,11 +17,9 @@ script_mod! { flow: Down spacing: 12 align: Center - on_render: ||{ - counter_label := Label{ - text: "Count: " + state.counter - draw_text.text_style.font_size: 24 - } + counter_label := Label{ + text: "Count: 0" + draw_text.text_style.font_size: 24 } } increment_button := Button{ @@ -44,15 +35,15 @@ script_mod! { pub struct App { #[live] ui: WidgetRef, + #[rust] + counter: i32, } impl MatchEvent for App { fn handle_actions(&mut self, cx: &mut Cx, actions: &Actions) { if self.ui.button(cx, ids!(increment_button)).clicked(actions) { - script_eval!(cx,{ - mod.state.counter += 1 - ui.main_view.render() - }); + self.counter += 1; + self.ui.label(cx, ids!(counter_label)).set_text(cx, &format!("Count: {}", self.counter)); } } } diff --git a/libs/makepad_test/src/runtime.rs b/libs/makepad_test/src/runtime.rs index 13c28ed75..ecad4edbf 100644 --- a/libs/makepad_test/src/runtime.rs +++ b/libs/makepad_test/src/runtime.rs @@ -85,6 +85,11 @@ pub struct TestConfig { pub startup_pause: Duration, pub action_delay: Duration, pub keep_open: Duration, + pub android: bool, + pub device_serial: Option, + pub adb_path: Option, + pub android_port: u16, + pub android_native_activity: bool, } impl TestConfig { @@ -126,6 +131,11 @@ impl TestConfig { startup_pause: env_duration_ms("MAKEPAD_TEST_STARTUP_DELAY_MS"), action_delay: env_duration_ms("MAKEPAD_TEST_ACTION_DELAY_MS"), keep_open: env_duration_ms("MAKEPAD_TEST_KEEP_OPEN_MS"), + android: android_test_enabled(), + device_serial: android_device_serial(), + adb_path: android_adb_path(), + android_port: android_hub_port(), + android_native_activity: env_truthy("MAKEPAD_TEST_NATIVE_ACTIVITY"), }) } @@ -157,6 +167,13 @@ impl TestConnection { Self::Remote(connection) => connection.recv_timeout(timeout), } } + + fn studio_addr(&self) -> Option { + match self { + Self::InProcess(connection) => connection.studio_addr(), + Self::Remote(_) => None, + } + } } struct TestAppInner { @@ -208,7 +225,9 @@ impl TestApp { } fn start_once(config: TestConfig) -> TestResult { - let (connection, build_id) = if visible_mode_enabled() { + let (connection, build_id) = if config.android { + start_android_app(&config)?

It dies between frames, and the next thing that touches it is a resource creation or a buffer map -- of which this file had 76 unwrapped, plus three `std::process::exit(1)`. So the usual outcome of a GPU driver reset, a TDR or a hybrid-GPU transition across suspend/resume was a panic, and the graceful path was unreachable. Route the calls a dead device actually reaches through `D3d11Cx::note_error`, which asks `GetDeviceRemovedReason` rather than pattern-matching the HRESULT the failing call happened to return -- creation calls do not reliably return the two DXGI device-lost codes, while the device itself always knows and keeps saying so. That answer sets a process-wide `device_lost` latch and logs once. The softened sites are the ones a dead device lands on first: draw-list and pass uniform buffers, which upload every frame with no dirty gate; texture and render target creation; and shader object creation, whose `CxOsDrawShader::new` already returned `Option` with both callers handling `None`. Three latent bugs fall out of auditing them, each of which loses content permanently rather than noisily: - `update_vec_texture` consumed the dirty flag with `take_updated()` and then returned early when the pixel buffer was out on loan, so a texture that hit that window was never uploaded again. For the glyph atlas that means all text disappears for the life of the process. The Metal backend already guards this; D3D11 did not. - `hlsl_compile_shaders` drains `compile_set` destructively, so a shader whose object creation failed was dropped from the queue forever and everything drawn with it silently stopped rendering. Failed creations go back in the queue. - `render_view` unwrapped the geometry index buffer but passed the vertex buffer through as an `Option`, so a missing one bound null and drew nothing with no error anywhere. Both are now checked together, and a draw call with either missing is skipped under a `debug_assert!` that it only happens on a lost device. Co-Authored-By: Claude Opus 5 (1M context) (cherry picked from commit cc980805b5774253e592e183f577c5ba08ce85db) * d3d11: rebuild the device and every GPU resource after a device loss Detection landed already: present() sets a per-window device_lost and the paint loop stops re-dirtying the pass. Nothing rebuilt anything, so the window stayed frozen until the app was restarted. Recovery runs at the top of win32_event_callback, the one place holding both &mut D3d11Cx and &mut Vec while nothing is mid-render. It releases each window's swap chain, back buffer, view and paint-beat registration (DXGI allows one flip-model chain per HWND, so the dead one must be gone first), recreates the device tier when the device really is gone, drops every GPU handle the Cx holds, and rebuilds each swap chain against the same HWND. Clearing handles is only half of a sweep. Geometry and instance uploads are gated on dirty flags cleared unconditionally once the upload runs, and textures on a dirty rect consumed by take_updated, so every gate is re-armed or the empty slot is never refilled. The CPU-side sources all survive: texture pixels live in TextureFormat::Vec*, geometry in CxGeometry, and shaders keep their compiled DXBC plus the on-disk cache, so recovery recreates shader objects without compiling any HLSL. Retries are spaced 250ms to 4s and driven by the existing signal heartbeat rather than a new timer, because the GPU can stay absent for a long time. While lost, the loop is forced to Wait at both EventFlow decisions -- every condition that would otherwise choose Poll is unsatisfiable when nothing can paint, so it would spin for the whole outage -- and pending screenshot requests are failed, both to release their requester and because a non-empty queue is itself one of those conditions.

Borrowing reads the same Option without touching the refcount; only IASetVertexBuffers genuinely needs an owned Option, which is what the code built before. Co-Authored-By: Claude Opus 5 (1M context) (cherry picked from commit ecfab9a9355d50754a7117de8303d66f8919b2ee) * d3d11: make the device-loss recovery actually work, and add a way to exercise it Three defects, each of which stopped recovery dead, and none of which is visible without running it. `MAKEPAD_D3D11_TEST_DEVICE_LOSS=` forces a full device recreation on a timer so the path can be exercised without a driver reset; a real removal cannot be provoked from inside the process. It is a stronger test than merely setting the latch, because the device really is replaced, so any GPU object the sweep fails to rebuild still belongs to the old device and cannot render against the new one. - The sweep called `set_updated` on every texture, which panics for anything that is not a `Vec*` format. The first render target it reached took the app down. Only vec textures carry a dirty rect; render targets, depth buffers and shared textures have no CPU-side contents and get their alloc record cleared instead. - Every rebuilt swap chain failed with `E_ACCESSDENIED`. DXGI allows one flip-model swap chain per HWND at a time and D3D11 destroys lazily, so the immediate context's own reference to the back-buffer view kept the old chain -- and its claim on the window -- alive after the application had dropped every handle it held. `ClearState` + `Flush` once, after all the windows have released and before any rebuild. - The post-recovery redraw marked every pass slot dirty, including ones nothing had drawn into, and `draw_pass_to_texture` unwraps `main_draw_list_id` immediately. Only passes that have one are marked. Verified against a release build: six consecutive forced device recreations, no panics, the UI rendering correctly after each (text included, so the glyph atlas re-uploads from its retained pixels), `ResizeBuffers` working on a rebuilt chain, handle count flat across recoveries, and the loop idle afterwards.

VIR — the vector IR between the splash pure-math subset detector and +//! the math backends (see platform/script/MATH_AOT.md). +//! +//!
