* Handle wasm data segments and manage brotli artifacts
Add full support for parsing, encoding and rewriting Wasm data segments: introduce WasmDataSegmentKind (Active/Passive), helpers to encode varints and const i32 exprs, and functions to rewrite the data section or replace a section payload. Update wasm_split_data_segments to preserve passive segments and data.count (section 12), only extract active segments into a separate split blob, and adjust segment counting and tests accordingly.
Bump brotli dependency to 8.0 in tools, and add remove_brotli_artifact to remove leftover .br files when brotli compression is disabled. Call this cleanup in cargo_makepad build/copy paths and when removing split data, and add .bin MIME mapping and print mapping for .bin in the server output. Tests updated to cover passive segments and data_count preservation.
* Support split data v2 and wasm rebuild
Add support for a new split data format (version 2) and the ability to rebuild a WASM module with its data section. wasm_bridge.js: parse v1/v2 split blobs, return {version, segments}, add varint encode/decode helpers, encode split-data section payloads, implement rebuild_split_wasm, fetch-and-instantiate logic to fetch both wasm and split blobs and handle v1 preloaded splits or rebuild for v2. wasm_strip.rs: bump split data version to 2, include segment kind and memory_index in encoded split data, preserve passive segments, update encoding/decoding and tests, and return the updated segment count. tools/cargo_makepad/src/wasm/compile.rs: separate target spec directories for threaded vs single builds (threads/single).
* basic splitting
* Instantiate secondary Wasm module in threads
Store and expose a compiled secondary WebAssembly module from the primary module, and ensure worker contexts (Web Worker and AudioWorklet) instantiate that secondary module before running thread entrypoints. Changes: save _secondary_module on primary_wasm in wasm_bridge, include secondary_module in WasmWebBrowser info, and add async instantiate_secondary logic + awaits in audio_worklet and web_worker so the secondary module is instantiated with {env, primary: primary_wasm.exports} prior to initializing stack/TLS or starting execution. This ensures the secondary module can import primary exports in threaded contexts and prevents race conditions by waiting for instantiation to complete.
* more cleanups

* Cold-first auto wasm split with fallback
Add a cold-only function-splitting mode and automatic fallback to preserve startup-safe behavior. Introduces wasm_split_functions_cold() and a split_auto flag to run a cold-first pass that moves defer-safe cold functions to a secondary wasm; if no useful cold candidates are found the build falls back to the normal startup-path function split so the app still gets a secondary payload.
Changes include: update to CLI help text, new split_auto handling in WasmConfig, AutoSplitOutcome variants, compile logic to prefer cold-only splits then fall back to the regular split, adjusted logging for automatic mode, and README wording clarifications. Files touched: README.md, libs/wasm_strip/src/wasm_strip.rs, tools/cargo_makepad/src/main.rs, tools/cargo_makepad/src/wasm/compile.rs, tools/cargo_makepad/src/wasm/mod.rs.
* Tune brotli compression parameters
Adjust brotli settings in tools/cargo_makepad/src/wasm/compile.rs: increase buffer size from 4KB to 64KB, lower quality from 12 to 11, and raise window size from 22 to 24. This balances throughput and compression ratio for larger wasm artifacts—bigger buffer and window can improve compression effectiveness while slightly reducing CPU cost by lowering quality.
* Add optional wasm-opt optimization flag
Introduce an optional --wasm-opt option that runs Binaryen's wasm-opt -Os on built wasm when available. Adds a wasm_opt flag to WasmConfig (default false), parses the CLI option, and integrates a try_wasm_opt helper that writes a temp wasm, invokes wasm-opt, reads back the optimized output and prints size/reporting while gracefully falling back on errors. The wasm-opt step runs before the existing split/strip pipeline. Also updates CLI help text, minor Cargo.toml formatting changes, and removes a vendor UPSTREAM.md reference.
* update readme
* Shorten split exports to $s/$p and use base62
Rename split-related exports/imports to shorter identifiers and compress numeric indices using base62. Changes: export/table slot prefix changed from "__mp_split_table"/"__mp_split_slot_*" to "$s" and the primary import namespace from "primary" to "$p" across wasm_bridge, audio_worklet, and web_worker. Introduces encode_base62 in wasm_strip to emit $f/$t/$m/$g names with base62-encoded indices, and updates primary/secondary module generation and tests accordingly. Also includes minor JS formatting/whitespace cleanups and small safety/compatibility tweaks during WebAssembly instantiation.
* Preload WASM modules and set cache headers
Inject modulepreload links into generated HTML (conditionally including wasm_bridge and bindgen when bindgen is enabled, otherwise preloading web_gl only) to improve module loading. Also change served asset Cache-Control from max-age=0 to max-age=86400 (1 day) for both brotli-compressed and uncompressed responses to enable client caching and reduce repeated fetches.
* Minify JS when copying before brotli
Add a lightweight JS minifier and apply it in cp_brotli for .js files. Introduces minify_js which strips line/block comments, collapses unnecessary whitespace, preserves strings/escaped characters and simple regex literals (heuristic), and removes empty lines. cp_brotli now attempts to read and minify .js input and write the minified output to the destination (falling back to cp on read error), then continues to optionally brotli-compress the result. This reduces payload size prior to compression with a small, simple minification step.
* Format web.js and disable XR capability checks
Apply consistent JS formatting (spacing, brace placement, object literal spacing, and minor whitespace cleanups) across platform/src/os/web/web.js. Replace the previous XR capability detection with a no-op (query_xr_capabilities now returns Promise.all([])) and remove the await call in load_deps so XR checks are not performed during startup. Also includes minor non-functional tweaks (timers, audio worklet messaging formatting, fetch call spacing, and various input/keyboard handler cleanups). Overall changes are primarily stylistic with the notable behavior change of disabling XR capability probing.
* Add WASM no-cache headers; remove web video arms
Set Cache-Control to "no-store, must-revalidate" (plus Pragma/Expires) for .wasm responses while keeping max-age=86400 for other assets; wire these into the HTTP response headers. Also remove the explicit VideoSource::InMemory and VideoSource::Filesystem match arms from the web platform code (they previously logged errors and emitted VideoDecodingError events).
Video playback: extended API with volume, playback rate, seek ranges,
buffered ranges, can_play_type, audio-only mode. Unified player wrapping
native backend (AVPlayer/GStreamer/MediaFoundation) with software fallback.
YUV shader pipeline (BT.601/709/2020, NV12 biplanar, rotation).
Camera: V4L2 backend (Linux), expanded NDK Camera2 (Android), AVCapture
stream refactor (iOS/macOS) with shared session architecture. NV12
zero-copy paths on iOS (CVMetalTextureCache) and Android (AImage planes).
Camera preview modes (texture/native/auto).
Video encoding: H264 hardware encode on Apple (VideoToolbox) and Android
(MediaCodec). Camera-to-encoder pipeline with pixel buffer passthrough.
Media plugin system: externalized codec implementation via MediaPlugin
trait. MsePlayer, VideoFrameDecoder, MediaVideoEncoder, SoftwareVideoPlayer
interfaces. Runtime codec capability query and merge.
Includes camera example app.

Replace broad cx.load_all_script_resources() calls with a targeted cx.load_script_resource(handle) to only request the specific resource needed. Refactor script resource loading (platform/src/script/res.rs) by extracting load_script_resource_impl(handle, crate_manifests) and exposing load_script_resource(handle); keep load_all_script_resources() by iterating per-handle. Improve wasm handling: resolve web_url per-resource, set explicit error states when missing, and fire async HTTP requests safely. Remove an early call to load_all_script_resources() from web startup. Additional changes: serve precompressed .br files in the local wasm dev server (with COOP/COEP headers when threaded), add wasm-specific font/theme script entries for widgets, and update various callers (draw shaders, widgets, math_view, gltf/view_splat, image) to use the per-handle loader. These changes reduce unnecessary global loads and limit network/file operations to only required resources.
* selection: clipboard delegate, primary selection, mobile UI, handles, accessibility
Level 0: Route clipboard through Makepad instead of arboard. Custom
ClipboardDelegate in havishell forwards set_text/get_text/clear through
Makepad's CopyToClipboard and pending paste state. Fix Wayland serial
constraint by queuing CopyToClipboard when no serial is available.
Level 1: Primary selection (Linux). Add CxOsOp::SetPrimarySelection,
Wayland zwp_primary_selection_device_manager_v1 protocol bindings, X11
PRIMARY atom handling. HAVI stores selection text in SharedDocumentSelection
and calls set_primary_selection on change.
Level 2: Mobile clipboard actions UI. Long-press selects word and shows
native clipboard toolbar. TextCopy/TextCut events return selection text.
Level 3: Selection handle API. Add CxOsOp Show/Update/HideSelectionHandles,
Event::SelectionHandleDrag, and HAVI integration for handle drag events.
Platform stubs for all backends.
Level 4: Accessibility plumbing. Add CxOsOp::AccessibilityUpdate with
type-erased Box<dyn Any + Send> payload. HAVI implements
notify_accessibility_tree_update to forward accesskit::TreeUpdate through
Makepad. Platform no-op stubs.
* wayland: handle primary selection data_offer child objects

Introduce a single-threaded wasm build mode and add defensive runtime handling for missing wasm threading support.
- CLI: add --no-threads flag and WasmConfig.threads to control threaded vs single-threaded builds. Parse and strip wasm-specific options before forwarding build/run args.
- Build: select target features and RUSTFLAGS based on threading; omit atomics/bulk-memory features for single-threaded builds. Adjust generated server instructions to require COOP/COEP only for threaded builds.
- Dev server: conditionally include COOP/COEP headers when serving threaded wasm artifacts.
- JS runtime (platform/src/os/web/web.js): guard audio worklet startup and thread creation on wasm._has_thread_support; make alloc_thread_stack return null with clear console warnings when required exports or alignment are missing; pass allocated thread_info to workers.
These changes enable building and running a single-threaded wasm variant without COOP/COEP server requirements and improve runtime resilience when threading features are unavailable.
The Contents.json only had a single universal+platform entry, which is
only recognized by iOS 16+. Add classic per-idiom entries (iphone, ipad,
ios-marketing) so actool compiles both sets into Assets.car. iOS 15
falls back to the idiom-based entries.

Refactor app icon handling into a unified app_icon module that replaces
the old window_icon.rs. Build-time icon generation produces platform-
native formats (ICO with multiple sizes for Windows, ICNS for macOS,
multi-resolution PNGs for Linux/Wayland/X11).
Add `cargo makepad desktop` subcommand for desktop packaging with
automatic icon detection from MAKEPAD_APP_ICON_PATH env var, or from
Cargo package metadata.
Resolve binary names from [[bin]] targets in Cargo.toml so .app bundles,
.exe outputs, and APK labels use the correct name instead of defaulting
to the package name.
Use llvm-rc for Windows .res generation (cross-compilation compatible)
with absolute link paths for reliable resource embedding.

Add WindowIcon and WindowIconBuffer types to platform/src/window.rs with
RGBA8 pixel buffer data. Embed a default 64x64 Makepad icon generated at
runtime (dark rounded rect with white M glyph).
Platform backends:
- Windows: CreateIcon from RGBA->BGRA data, set on WNDCLASSEXW.hIcon
- X11: XChangeProperty with _NET_WM_ICON atom (RGBA->ARGB u32 array)
- macOS: NSBitmapImageRep + NSImage, setApplicationIconImage on NSApp
- Wayland: vendor xdg-toplevel-icon-v1 protocol, regenerate bindings,
bind wl_shm + xdg_toplevel_icon_manager_v1 globals, create shm buffer
icon when compositor supports it, silent fallback to app_id otherwise.
Use configurable create_app_id field (default "Makepad").
Codegen: extend tools/wayland_codegen to generate xdg toplevel_icon
bindings into libs/linux/wayland-protocols/src/xdg.rs.

* Add macOS video playback support using AVPlayer + CVMetalTextureCache
Extends the Video widget from Android-only to also support macOS with
hardware-accelerated, zero-copy video rendering through Metal. Uses
AVPlayer for decoding and CVMetalTextureCache to map decoded frames
directly to MTLTextures without CPU copies.
Key changes:
- New AppleVideoPlayer module (AVPlayer + CVPixelBuffer → MTLTexture pipeline)
- FFI bindings for CVMetalTextureCache, CMTime, and related Apple APIs
- Video frame polling integrated into macOS paint cycle
- TextureFormat::VideoRGB ungated from Android-only to all platforms
- Video widget made cross-platform (TextureHandleReady wait is Android-only)
- Fixed shader aspect ratio bug (&&→|| for non-positive dimension check)
- Added video demo to uizoo and scratchpad examples

* fix: add **/* glob to Linux NDK unzip to match subdirectories
`*` alone doesn't match `/` on Linux unzip builds with WILD_STOP_AT_DIR,
causing only top-level files to be extracted. Adding `**/*` ensures bin/,
lib64/, sysroot/ subdirectories are included.
* Auto-bundle NDK shared library deps (e.g. libc++_shared.so) into APK
When libmakepad.so has NEEDED entries for shared libraries provided by
the NDK sysroot (like libc++_shared.so from C++ dependencies), those
libraries were not being included in the APK, causing runtime dlopen
failures on device.
Add bundle_ndk_shared_deps() which uses the NDK's llvm-readelf to scan
libmakepad.so for NEEDED entries, then copies any matching .so files
from the NDK sysroot base lib dir into the APK. System libraries
(present in the API-level subdirectory) are excluded since they are
provided by the Android OS at runtime.
The detection is general-purpose and not hardcoded to any specific
library name.
* fix: make SYS_GETTID arch-conditional (186 on x86_64, 178 on aarch64)
The constant was hardcoded to 178 (correct for aarch64 but maps to
query_module on x86_64), causing Android's seccomp filter to kill the
process immediately on x86_64 emulators.
* Upgrade Android NDK from r25 to r28, fix x86_64 seccomp crash
cargo_makepad:
- sdk.rs: NDK version 25.2.9519653 → 28.2.13676358, download URLs r25c → r28b
- sdk.rs: Update NDK_IN extract paths for all platforms (Windows, macOS, Linux)
- sdk.rs: macOS NDK extraction is now host-aware (darwin-aarch64 for Apple Silicon)
- compile.rs: MacosAarch64 uses native darwin-aarch64 prebuilt (no more Rosetta)
- compile.rs: ndk_prebuilt_dir() split for MacosX64 vs MacosAarch64
platform:
- libc_sys.rs: Make SYS_GETTID arch-conditional (186 on x86_64, 178 on aarch64)
Was hardcoded to 178 which maps to query_module on x86_64, causing
Android seccomp to kill the process on x86_64 emulators
- android.rs: Add pub display field on CxOs, pub make_current() on CxAndroidDisplay
for Servo embedding support
* Fix GLSL struct constructor crash on Android GLES drivers
The r28 script-based shader backend (shader_glsl.rs) generates GLSL
struct constructor syntax in the vertex/fragment main() unpack code,
e.g.: vb_geom = QuadVertex(vec2(packed_geometry_0.x, ...));
Some GLES drivers (notably Android emulator ANGLE/SwiftShader) reject
this with 'Structure constructor arguments do not match structure
fields', even though it's valid per the GLES 3.0 spec.
This is a regression from r28. The old r25 shader compiler
(generate_glsl.rs) used VarUnpacker::unpack_var which generated direct
swizzle assignments (vb_geom.xy = packed_geometry_0.xy), never struct
constructors in the unpack path. The r25 branch is not affected.
Fix: generate per-sub-field assignments for struct-typed variables in
the main() geometry/instance/varying unpack code, matching the r25
behavior. Struct constructors in user shader function bodies are
unaffected.
* fix(android): Proper fullscreen support on API 30+ and FullscreenWindow/NormalizeWindow ops
Android platform changes:
- Add CxOsOp::FullscreenWindow handler: sets os.fullscreen flag and calls JNI setFullScreen
- Add CxOsOp::NormalizeWindow handler: clears os.fullscreen and exits fullscreen
MakepadActivity.java:
- onCreate: On API 30+, switch from legacy Theme.NoTitleBar.Fullscreen to
Theme_DeviceDefault_NoActionBar to avoid FLAG_FULLSCREEN conflict
- onCreate: Call setDecorFitsSystemWindows(false) and set
LAYOUT_IN_DISPLAY_CUTOUT_MODE_ALWAYS before setContentView so SurfaceView
is laid out at y=0 from the start
- Refactor setFullScreen into applyFullScreen with proper WindowInsetsController
API on API 30+ (hide/show statusBars + navigationBars)
- Legacy path (pre-API 30) uses full immersive sticky flags
- ResizingLayout.onApplyWindowInsets: Return WindowInsets.CONSUMED to prevent
system bar insets from offsetting child SurfaceView
* Fix Android touch radius DPI scaling and revert aggressive fullscreen inset handling
- Divide touch.radius by dpi_factor alongside touch.abs for correct touch sizing
- Return insets instead of consuming them in ResizingLayout so child views get proper insets
- Remove premature setDecorFitsSystemWindows/cutout mode override; let apps opt in via FullscreenWindow
* Make DrawImage image_scale/image_pan fields pub
Needed by external crates (e.g. servo makepad_shell) that create custom
widgets using DrawImage and need to flip the Y axis for GL render textures.
