+
+ WebCore::CaptionUserPreferencesMediaAF should use a weak observer with CFNotificationCenter
+ <https://webkit.org/b/231550>
+ <rdar://problem/84129338>
+
+ Reviewed by Darin Adler.
+
+ * SourcesCocoa.txt:
+ * WebCore.xcodeproj/project.pbxproj:
+ - Add CaptionUserPreferencesMediaAF.mm.
+
+ * page/CaptionUserPreferences.cpp:
+ (WebCore::CaptionUserPreferences::create): Add.
+ * page/CaptionUserPreferences.h:
+ (WebCore::CaptionUserPreferences):
+ - Make subclass of RefCounted<> and CanMakeWeakPtr<>.
+ (WebCore::CaptionUserPreferences::create): Add.
+ (WebCore::CaptionUserPreferences::CaptionUserPreferences):
+ - Move constructor to protected visiblity with explicit keyword,
+ and add static create() method.
+
+ * page/CaptionUserPreferencesMediaAF.cpp:
+ (WebCore::userCaptionPreferencesChangedNotificationCallback):
+ - Update to use extractCaptionUserPreferencesMediaAF() for
+ Cococa platforms. Note that -> is used for two different
+ `userPreferences` variable types based on the platform.
+ (WebCore::CaptionUserPreferencesMediaAF::create): Add.
+ (WebCore::CaptionUserPreferencesMediaAF::CaptionUserPreferencesMediaAF):
+ - Move initialization of m_listeningForPreferenceChanges to
+ class definition.
+ (WebCore::CaptionUserPreferencesMediaAF::~CaptionUserPreferencesMediaAF):
+ - Update to use m_weakObserver as observer for Cocoa platforms.
+ (WebCore::CaptionUserPreferencesMediaAF::setInterestedInCaptionPreferenceChanges):
+ - Update to use m_weakObserver as observer and
+ _CFNotificationObserverIsObjC in suspension behavior for Cocoa
+ platforms.
+
+ * page/CaptionUserPreferencesMediaAF.h:
+ (WebCore::CaptionUserPreferencesMediaAF::create): Add.
+ (WebCore::CaptionUserPreferencesMediaAF::CaptionUserPreferencesMediaAF):
+ - Move constructor to private visiblity, and add static create()
+ method.
+ (WebCore::CaptionUserPreferencesMediaAF::extractCaptionUserPreferencesMediaAF): Add.
+ (WebCore::CaptionUserPreferencesMediaAF::createWeakObserver): Add.
+ (WebCore::CaptionUserPreferencesMediaAF::m_weakObserver):
+ - Add m_weakObserver instance variable for use with
+ CFNotificationCenter.
+ (WebCore::CaptionUserPreferencesMediaAF::m_listeningForPreferenceChanges):
+ - Move initialization of m_listeningForPreferenceChanges here
+ from the constructor.
+
+ * page/cocoa/CaptionUserPreferencesMediaAFCocoa.mm: Add.
+ (-[WebCaptionUserPreferencesMediaAFWeakObserver initWithWeakPtr:]):
+ (-[WebCaptionUserPreferencesMediaAFWeakObserver userPreferences]):
+ - Declare and implement
+ WebCaptionUserPreferencesMediaAFWeakObserver class for use as
+ a weak CFNotificationCenter observer.
+ (WebCore::CaptionUserPreferencesMediaAF::createWeakObserver): Add.
+ - Helper method to call from C++ that creates weak observer
+ object from Objective-C++.
+ (WebCore::CaptionUserPreferencesMediaAF::extractCaptionUserPreferencesMediaAF): Add.
+ - Helper method to extract RefPtr<CaptionUserPreferencesMediaAF>
+ from CFNotification observer parameter.
+
+ * page/PageGroup.cpp:
+ (WebCore::PageGroup::ensureCaptionPreferences):
+ - Switch to using new create() methods.
+
+ * page/PageGroup.h:
+ (WebCore::PageGroup::m_captionPreferences):
+ - Change from std::unique_ptr<> to RefPtr<>.
