In April 2023, I made _WKRemoteObjectRegistry deserialization stricter by not allowing subclasses of the specified class to be deserialized. To make this transition as smooth as possible, I added a set of common and safe always-allowed subclasses including NSMutableString and several others. Telemetry indicates this increased the crash rate and this is to bring that crash rate back down. After analyzing 100% of the recent crash reports with useful data, I found 4 things that will help: 1. Allowing a class named "NSDecimalNumberPlaceholder" which is a subclass of NSDecimalNumber that some internal frameworks apparently use and give to Safari in a path that serializes it. Allow this. 2. Some crash logs indicate that NSDate objects are failing to decode because they are not in the set of allowed classes. There are some JS to ObjC object converters (such as the one used in WKWebView.callAsyncJavaScript) that can produce an NSDate, and this is ok and safe. Allow this too. 3. There are logs that indicate that sometimes a class is being sent from one process to another, and the receiving process has not loaded the dylib containing the ObjC class so the ObjC runtime can't find it. Add telemetry to get this class name for future diagnosis. 4. There are logs that indicate that sometimes a class is being sent that does not conform to NSSecureCoding according to NSCoder. Also add telemetry to get this class name for future diagnosis, but in this case I needed to add a @try/@catch because validateClassSupportsSecureCoding either returns YES or throws an ObjC exception, so to get the class name to CRASH_WITH_INFO I need to catch. * Source/WebKit/Shared/API/Cocoa/WKRemoteObjectCoder.mm: (alwaysAllowedClasses): (validateClass): (decodeObject): Canonical link: https://commits.webkit.org/269185@main Identifier: 267815.308@safari-7617.1.11.12-branch Commit: 6af60fb521264fbcafe8e915bcd0d067c88e5706 https://github.com/WebKit/WebKit/commit/6af60fb521264fbcafe8e915bcd0d067c88e5706 Author: Myah Cobbs <mco...@apple.com> Date: 2023-10-17 (Tue, 17 Oct 2023) Changed paths: M Configurations/Version.xcconfig Log Message: ----------- Versioning.
