…strumentation via WeakHashMap Track wrapped windows in a thread-safe WeakHashMap so close() can restore each window's original callback chain, preventing an orphaned SentryWindowCallback from persisting after Sentry.close(). Also handle the case where another wrapper (e.g. Session Replay) has been installed on top of ours — we skip chain mutation but still invoke stopTracking() to release resources. Guards against racing lifecycle callbacks (main thread) and close() (possibly bg thread). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Track wrapped windows in a WeakHashMap so GestureRecorder skips re-wrapping already-instrumented windows and can locate its own recorder even when another wrapper (e.g. UserInteractionIntegration) has been installed on top of it. When our wrapper is buried in the callback chain, inert() it instead of mutating the chain so unrelated instrumentation isn't broken; the next replay session wraps on top with a fresh active recorder.

… cache entry on stop Two follow-ups to the buried-wrapper path: - stopTracking() now sets an inert flag that short-circuits handleTouchEvent, so a SentryWindowCallback that can't be cut out of the chain stops forwarding events to its gesture detector and listener. Without this, the "stopped" wrapper kept emitting ui.click breadcrumbs, so as soon as a fresh wrapper was installed on top the duplicates came back. - unwrapWindow removes the wrapped window from the tracking map in the buried path too. Previously only the top-of-chain path cleared it, which meant the next startTracking() found a stale (but alive, since the inert wrapper is still referenced by the chain) entry and returned early, permanently losing gesture tracking for that window.

📜 Description
If anything installs a
Window.Callbackon top of ourSentryWindowCallbackafterstartTracking()(a third-party library, our own Session Replay, etc.), ourstopTracking()path couldn't recognize our wrapper —window.getCallback() instanceof SentryWindowCallbackwasfalse— so it was left in the chain and kept firingSentryGestureListener. Every touch then produced twoui.clickbreadcrumbs — one from the currently-installed wrapper and one from the buried stale one.Fix: both integrations now track their wrappers in a
WeakHashMap<Window, WeakReference<…>>:UserInteractionIntegration— onstopTracking(), if our wrapper is no longer at the top of the chain, we still locate it via the map and callstopTracking()on it to release resources. When our wrapper is at the top, we restore the original delegate as before. Map access is guarded by a lock so main-thread lifecycle callbacks don't race bg-threadclose().GestureRecorder(session replay) — same tracking pattern. When our recorder is buried, weinert()it (null thetouchRecorderCallback) instead of mutating the chain. ThetouchRecorderCallbackfield is now@Volatile varsoinert()can safely null it.Both integrations also skip re-wrapping a window that's already instrumented.
💡 Motivation and Context
See screenshot above — duplicate
ui.clickbreadcrumbs.Previous behavior relied on
window.getCallback() instanceof SentryWindowCallbackto detect and remove our wrapper, which only works when our wrapper is at the top. As soon as anything else wraps on top of us, detection fails, our stale wrapper stays installed, and every subsequent touch fires our listener twice.💚 How did you test it?
