From 61ebed0f950b6989dd767f7b21a8a0000f700239 Mon Sep 17 00:00:00 2001 From: Bob Date: Sun, 12 Jul 2026 17:53:48 +0000 Subject: [PATCH 1/5] feat(watcher): multi-browser WebWatcher with Firefox Compose toolbar support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Rebases #151 (FractalMachinist) onto current master, targeting only the watcher source files — no build-config or unrelated-file churn. Changes: - WebWatcher.kt: refactor using BrowserSessionTracker (extracted state machine), extractUrl() when-expression, KNOWN_BROWSER_PACKAGES set. Adds Firefox Compose toolbar support via rootInActiveWindow traversal (fixes silent empty results from the old findAccessibilityNodeInfosByViewId + bare testTag approach, verified on Fairphone 6 / Android 14 / Firefox 138). - AccessibilityNodeTraversal.kt: generic findNode/forEachNode helpers with correct recycle discipline (fixes child.recycle-before-return bug from #139). - BrowserSessionTracker.kt: pure session state machine, unit-testable without AccessibilityService or device. - UrlExtraction.kt: parseFirefoxAddressBarContentDescription, stripProtocol, processExtractedText — pure parsing, unit-testable. - extractTextByViewId: fixed AccessibilityNodeInfo leak on API 24-32 (nodes from findAccessibilityNodeInfosByViewId were never recycled). - maybeDumpTree: gated behind Log.isLoggable(TAG, Log.DEBUG); enable with `adb shell setprop log.tag.WebWatcher DEBUG`. No build-config changes needed. - WebWatcherTest.kt / CustomTabsWrapper.kt: updated instrumented tests. - BrowserSessionTrackerTest.kt / UrlExtractionTest.kt: new JVM unit tests (no device/emulator required). Note: master's aw-server-rust submodule already includes the emoji/JNI fix from aw-server-rust#547 (merged 2025-12-17), so no submodule bump is needed.

Prevents a node leak on every accessibility event that reaches a page with a WebView title. - WebWatcherTest: filter getAvailableBrowsers() to KNOWN_BROWSER_PACKAGES so the test skips URL handlers that WebWatcher doesn't emit events for, avoiding timeouts on devices with additional URL handler apps installed.
