Summary: # Changelog: [Internal] There is no implementation for this method and it is unused. This is actually part of `HostAgent`. Differential Revision: D87220192
Summary: # Changelog: [Internal] Introduces a TracingDelegate that will receive tracing-related events on the Host side. We can't give synchronous access to tracing state to Host directly, since there is no guarantee that this call will happen on the inspector thread. Example: - `HostTarget::tracingState()` call may happen on UI thread, or whatever thread the Host is using, which reads `traceRecoding_` value. - At the same time, the `stopTracing()` call that will invalidate `traceRecording_` could happen on inspector thread. This is a pre-requisite for a better threading model, since we are going to be doing much frequent write operations from the Host side to record frame timings or screenshots. Differential Revision: D86205686
Summary: # Changelog: [Internal] An implemementation of HostTargetTracingDelegate on the android side. Notes: - `getTracingState_next()` function will replace `getTracingState()` in the diff on top. - `TracingStateListener `is temporarily added to `devsupport/interfaces`, will be moved to `devsupport/inspector` in one of the diffs on top. Differential Revision: D87123723
Summary: # Changelog: [Internal] Before this change, every `getTracingState()` call would go through jni to C++ to get the current state synchronously. This has a risk of data races, since we can't guarantee from which thread the Host will call this method. At the same time, the Tracing could be started from inspector thread, if this was initiated with CDP request. Instead, the state will be propagated asynchronously via `HostTargetTracingDelegate`, and then it will be encapsulated on the Host side. In android case, this will be part of the `ReactHostInspectorTarget`. Also removing no longer used code in `jsinspector-modern`. Differential Revision: D87123722
Summary: # Changelog: [Internal] This should not have been public in a first place. There are just no reasons for it, since Performance Monitor is still an internal concept of React Native Framework. Differential Revision: D87638584
Summary: Pull Request resolved: facebook#54632 # Changelog: [Internal] Tracing is a concept of Inspector. It should be part of the Inspector package, not general interfaces. The Inspector stack is the only mechanism that controls the tracing state of a Host. Reviewed By: cortinico Differential Revision: D87638583

Backports some CDP Performance features and stability improvements to `0.83-stable`. This includes: - Remaining implementation of Frame Timings and screenshot capture in performance traces (Android) - New support for Frame Timings and screenshot capture on iOS - Optimisations to trace chunk generation, memory usage during performance recording - `Page.captureScreenshot` (Android, iOS) All features remain gated behind feature flags (`fuseboxFrameRecordingEnabled`, `fuseboxScreenshotCaptureEnabled`). **Commits applied** - Define TracingCategory enum (facebook#54377) bd6c6bf - Use TracingCategory in TraceEvent (facebook#54378) ce60f27 - Simple parser for serialized tracing categories (facebook#54379) 62275b6 - Propagate tracing categories to recording state (facebook#54380) 3841ef0 - Re-land "Revert D85999774: [rn][android] Add FrameTiming module" (facebook#54502) 85905ad - Add screenshot category (facebook#54537) 5d9cb80 - Define HostTargetTracingDelegate (facebook#54622) be0dae0 - Define TracingDelegate for Android Host (facebook#54628) a212e95 - Use new API for tracing state on Android (facebook#54629) 532d0be - Internalize TracingState interface (facebook#54631) 58ec261 - Move TracingState interfaces to inspector package (facebook#54632) 10d0d99 - Rename values of TracingState enum (facebook#54630) be94707 - FrameTiming module to subscribe to Inspector tracing lifecycle (facebook#54633) 04ee02b - Clarify HostTracingProfile and HostTraceRecordingState (facebook#54677) ec92f12 - Introduce TimeWindowedBuffer (facebook#54679) d6ee54f - Keep tracing time window on TraceRecordingState (facebook#54673) e651563 - Define FrameTimingSequence (facebook#54674) 5b7d92f - Define an endpoint on HostTarget to capture frame timings (facebook#54672) f469aa3 - Extract frame trace events construction logic (facebook#54675) 57973fa - Define serializers for frame timings as part of HostTargetTracingProfile (facebook#54681) 587d360 - Propagate Frames data through Host (facebook#54671) 26ff069 - Cleanup no longer used jni layer for frame timings (facebook#54678) 9ba4ce6 - Fix screenshot typo (facebook#54742) 52186a3 - Add optional screenshot argument to FrameTimingSequence (facebook#54743) 57c29fc - Frame screenshot event generation (facebook#54744) b447d26 - Frame screenshots capture implementation (facebook#54745) f3c9a8d - BeginDrawing: INTENDED_VSYNC_TIMESTAMP -> VSYNC_TIMESTAMP (facebook#54765) 9221772 - Add frames category (facebook#54768) 31a0c9a - Specify correct category for SetLayerTreeId event (facebook#54769) cd055e9 - Reduce the screenshots size (facebook#54800) e4a5a56 - Remove Commit from FrameTimingSequence (facebook#54779) 39f7703 - Fix potential bitmap leaks in FrameTimingsObserver (facebook#55652) 3918dd1 - Capture initial screenshot when starting frame timing trace (facebook#55720) 863f5c0 - Refactor FrameTimingsObserver for multi-activity support (facebook#55740) 8230f3b - Reorder FrameTimingsObserver methods (facebook#55743) f56b295 - Increase frame capture quality, apply scaling after DPI normalization (facebook#55731) e5f9f5f - Fix FrameTimingsObverver to initiate PixelCopy on main thread (facebook#55744) d552f2a - Fix bitmap reuse race condition in FrameTimingsObserver (facebook#55745) 3924768 - Fix trailing frame capture after recording ended (facebook#55704) 47684ca - Move base64Encode into react/utils (facebook#55873) 422770d - Move screenshot Base64 encoding to trace serialization (facebook#55803) dc4c36e - Restore inspector addPage listener callback (facebook#55925) 8c763fc - Add tracing helper functions for RNDT traces in C++ and Kotlin (facebook#55935) 4f3f536 - Introduce fuseboxFrameRecordingEnabled flag, gate existing code (facebook#55941) 1aa7a32 - Implement Performance frames and screenshots on iOS (facebook#56015) 64a1a10 - Add pixel diffing to RCTFrameTimingsObserver (facebook#56043) 9d231af - Add dynamic sampling to frame screenshots (facebook#56048) d309cda - Switch trace event chunks from event count to size based (facebook#56080) d3b33f5 - Increase trace screenshot scale factor to 1x (facebook#56079) 972a30d - Add Page.captureScreenshot CDP support (facebook#56307) 77332d2 - Fix data race on PerformanceObserver entry buffer (facebook#56352) 5eb1ca1 - [LOCAL] Remove stale frame event code from PerformanceTracer - [LOCAL] Update Podfile.lock

Changelog: [Internal]
Tracing is a concept of Inspector. It should be part of the Inspector package, not general interfaces.
The Inspector stack is the only mechanism that controls the tracing state of a Host.
