✨ Features

• [Feature][Harmony] TemplateBundle support async decoding (28ed738) @pilipala195

  On the Harmony platform, ets code runs on the main thread by default. TemplateBundle.fromTemplate can block the main thread and causing app_freeze.
  This MR introduces the TemplateBundle.fromTemplateAsync interface, which allows callers to wait asynchronously using a Promise, thus avoiding blocking other operations on the main thread.

• [BugFix] Guard removal of layout node by checking parent and using actual parent (2ea58bb) @zhongyr

  In element-mode layout, removing a child's layout node assumed this
  element was its parent, which could be false and cause incorrect removals
  or crashes. Now we verify the child has a layout node and a parent, then
  remove it from its actual parent instead of unconditionally using
  this->sl_node_. This prevents invalid parent-child operations and
  stabilizes node removal paths.

  • Add null and parent checks before removal
  • Remove child via child->slnode()->parent()->RemoveChild(child->slnode())
  • Leave a FIXME to investigate mismatched parent relationships

• [BugFix] prefers lynxGroup in LynxViewBuilder (e86ca68) @nhsprite

  prefers lynxGroup in LynxViewBuilder so that lynxView in the same LynxViewGroup may still
  has seperate globalThis in js environment.

• [BugFix][Event] Fix a gesture conflict issue when Lynx cards overlapped. (936ece6) @rAY-ooo

  description:
  Previously, because OH_ArkUI_GestureEvent_GetNode was not supported, setting a HitTestBehavior of type Transparent would reset the event_dispatcher to that of the bottom-level Lynx card when multiple Lynx cards overlapped. This caused gesture comparison to fail, resulting in upper-level Lynx cards failing to respond to clicks.

  Therefore, we set the EventDispatcher to user_data on the gesture-bound node, and then retrieved the EventDispatcher from the node in the custom gesture determination interface to ensure consistency.

• [BugFix][Memory] Unify MemoryReportTimer to use LynxEventReporter thread. (6803306) @Tamerlx

  Refactors LynxMemoryReportTimer on both iOS and Android to use the shared LynxEventReporter.delayRunOnReportThread.

  This change replaces platform-specific timers (NSTimer, ScheduledExecutorService) with a single, centralized scheduling mechanism.

  This simplifies the code, unifies threading for all reporting tasks, and improves resource management by eliminating redundant timers and threads.

• [BugFix] Making sure that TemplateData is released properly (f626001) @nhsprite

  It's needed to make sure the templateData is released with the engine thread. In this patch
  an asscociated lynxContext is bind to templateData we will post the recycle runnable to

  Changes:

  • Make ResponseHandlerProxy inherit from std::enable_shared_from_this
  • Use weak_ptr in AddResourceListener callback to safely check if proxy
    still exists before invoking delegate callbacks
  • Prevent callback execution if proxy has been destroyed

  In embedded mode, ElementManager::RequestLayout directly calls TemplateAssembler::OnLayoutAfter. Inside OnLayoutAfter, the current context is cleared, which causes a null pointer exception when GetCurrentPipelineContext()->RequestFlushUIOperation is executed after ElementManager::RequestLayout finishes.

  As a solution, we moved RequestFlushUIOperation into ElementManager::RequestLayout to fix the issue where it was being called after the current context was cleared.

🚀 Optimization

• [Optimize] add trace to LynxView's onMeasure, onLayout, onAttachToWindow, onDetachedFromWindow functions. (eb5cb3e) @ShouruiSong

  This merge request aims to add tracing capabilities to LynxView’s critical lifecycle methods—onMeasure, onLayout, onAttachedToWindow, onDetachedFromWindow, and updateViewport—to enhance performance monitoring and issue diagnostics. These trace events will provide visibility into the execution of these methods for developers.

  1. Constant Definitions:

     • Added constants like LYNX_VIEW_ON_MEASURE, LYNX_VIEW_ON_LAYOUT, etc., in the TraceEventDef class and updated corresponding definitions in the lynx_android.api file.

  2. Trace Event Integration:

     • Added LYNX_VIEW tracing metadata to the beginSection method in the LynxTemplateRender class.
     • Introduced onTraceEventBegin and onTraceEventEnd methods in the LynxView class to wrap lifecycle method executions with trace events.

  3. Parameter Passing:

     • Critical parameters such as INSTANCE_ID, LYNX_VIEW, WIDTH_MEASURE_SPEC, HEIGHT_MEASURE_SPEC, and PARAMS are included in trace events for granular analysis.

  (cherry picked from commit aaa691ff7872d7c2c5b9abd05e6241eb531ecd50)

• [Optimize] Set exception handler to OnceTask such that we can see the error message from log box. (28afcb4) @ShouruiSong

  The core objective of this merge request is to enhance the OnceTask class by adding exception handling capabilities, enabling developers to view error details in logs. This exception handling mechanism improves code robustness and maintainability, facilitating issue diagnosis and resolution when exceptions occur.

  1. OnceTask Class Updates

     • Added a new constructor OnceTask(final Callable< T > task, Consumer< Exception > exceptionHandler) to lynx_android.api.
     • Introduced the mExceptionHandler member variable in OnceTask.java and implemented the new constructor. The get method now invokes mExceptionHandler.accept() when catching exceptions, provided the handler is non-null.

  2. Dependent Class Adjustments

     • Updated LynxUI.java and UIBody.java to instantiate OnceTask using the new constructor. Exception handling logic now triggers the context.handleException() method on errors.

  3. Test Case Additions

     • Added the testExceptionHandle method in OnceTaskTest.java to validate the exception handling functionality.

• [Feature] add IProcessViewInfoHook and ViewInfo to support reusing LynxEngine. (4b53d58) @ShouruiSong

  The primary goal of this merge request is to add IProcessViewInfoHook and ViewInfo to enable reuse of LynxEngine. These changes aim to improve system performance and resource utilization, allowing LynxEngine to process view information and rendering operations more efficiently.

  ViewInfo is a critical class for enabling the reuse of the Lynx Engine. It stores essential rendering metadata (e.g., layout coordinates, clipping boundaries, z-index). After decoupling the Platform View (e.g., Android/iOS native views) from LynxUI (the cross-platform UI abstraction layer), ViewInfo acts as a platform-agnostic data layer to coordinate drawing operations.

  IProcessViewInfoHook is a crucial class for enabling the reuse of the Lynx Engine. In the future, LynxUI will inherit IProcessViewInfoHook, and ViewInfo will hold an instance of IProcessViewInfoHook. At critical stages, ViewInfo will invoke the interface methods of IProcessViewInfoHook to record rendering information.

  this to get bytecode source.

• [Feature] LynxUI inherits and implements IProcessViewInfoHook to enable the reuse of the Lynx Engine's core logic. (fb97551) @ShouruiSong

  The primary goal of this merge request is to enable LynxUI to inherit and implement the IProcessViewInfoHook interface, thereby achieving reuse of the Lynx Engine's core logic.

  • The LynxUI class now implements the IProcessViewInfoHook interface, with new methods such as processViewInfo, dispatchProcessViewInfo, etc.

  • Related classes (e.g., LynxFlattenUI, UIBody, UIGroup) have added methods to handle rendering node updates, view detachment, and other operations.

  • Added the detachWithView method in LynxBaseUI and its subclasses to manage view detachment, including recursive detachment of child views.

  • The ViewGroupDrawingOrderHelper class now includes methods to retrieve drawing order indices and prepare drawing sequences, improving control over child view rendering.

• [Feature] Provides an API for the platform layer to communicate with the Layout thread. (3cf0f79) @ChrisChan0668

  The implementation details are as follows:

  • A new API, runOnLayoutThread , is added to LynxContext, which accepts a task as a parameter.
  • This task is passed to the C++ layer, and then, leveraging the Actor's capabilities, the task is posted to the Layout thread.
  • The execution of this task is triggered on the Layout thread.
    Based on this API, the platform layer can initiate operations on ShadowNode from any thread, ensuring that all ShadowNode-related operations are executed on the Layout thread.

• [BugFix] fix nested query component. (a0036d4) @nhsprite

  Nested calling query component may cause crash now, it's caused by modifing url_to_lifecycle_option_map_ while looping url_to_lifecycle_option_map_, eg: calling queryComponent in callback of queryComponent.
  It's reasonable to use extract to accquire lifecycleOption list from url_to_lifecycle_option_map_ first, and then call OnLazyBundleLifecycleEnd for each option. QueryComponent called in OnLazyBundleLifecycleEnd will just return because templateEntry is cached now.

  TODO: adding test cases for nested query component cases.

• [BugFix][Element] Fix page element not record when AttachToElementManager causing white screen (e2cf9a7) @usczz

  In the current implementation, the reused element bundle is deeply cloned and attached to the target ElementManager by TreeResolver. TreeResolver first sets the root element as its current page, which removes the old page from the internal NodeManager. Then, FiberElement's AttachToElementManager is called recursively for each element in the tree. PageElement overrides this behavior by first calling the base class's AttachToElementManager, which records its element ID in the NodeManager. After that, it calls SetFiberPageElement to set itself as the root and removes its element ID from the internal NodeManager, causing the PageElement entry to be deleted. This removal can lead to incorrect layout results when using UNSPECIFIED or AT_MOST measure specs, as these require looking up the corresponding element in the NodeManager during layout propagation.

  In this merge request, SetFiberPageElement will be called only in PageElement’s overridden AttachToElementManager method and will be invoked before the base class’s AttachToElementManager to ensure that the page element's entry remains in the NodeManager. Additionally, a DCHECK is added in layout_mediator's OnLayoutUpdate to verify that no element entries are missing from the NodeManager during layout result propagation.

• [BugFix][ZIndex] fix the negative zIndex insertion issue (d44db20) @linxs0211

  The element container has a should_skip_index_calculation logic that skips index calculation if there are no zIndex children and insertion is at the end (ref=null). However, it doesn't account for negative_z_children_, causing incorrect index calculation. It's updated so that if any zIndex exists, index calculation is forced.

• [BugFix][Element] Fix shorthand CSS Property with CSS Variable value is reset in threaded element resolution (83a599b) @usczz

  In the current implementation, during threaded element resolution, CSS Variable resolution is postponed as an engine thread task. However, when handling shorthand CSS properties, the actual values are not resolved, leaving only their keys in the parsed_style_map. Later, in the engine thread task that refreshes the CSS styles, the shorthand properties are expanded into longhand properties. During the diffing process between the previous and current style maps, shorthand properties are mistakenly included in the list of properties that require resetting.

  In this merge request, shorthand properties are excluded from the construction of reset_style_ids when comparing the previous parsed style with the new parsed style, preventing them from being reset unintentionally.
