     54 # Chromium's version of WebCore includes the following Objective-C classes. The
     55 # system-provided WebCore framework may also provide these classes. Because of
     56 # the nature of Objective-C binding (dynamically at runtime), it's possible for
     57 # the Chromium-provided versions to interfere with the system-provided
     58 # versions. This may happen when a system framework attempts to use
     59 # core.framework, such as when converting an HTML-flavored string to an
     60 # NSAttributedString. The solution is to force Objective-C class names that
     61 # would conflict to use alternate names.
     62 #
     63 # This list will hopefully shrink but may also grow. Its performance is
     64 # monitored by the "Check Objective-C Rename" postbuild step, and any
     65 # suspicious-looking symbols not handled here or whitelisted in that step will
     66 # cause a build failure.
     67 #
     68 # If this is unhandled, the console will receive log messages
     69 # such as:
     70 # com.google.Chrome[] objc[]: Class ScrollbarPrefsObserver is implemented in both .../Google Chrome.app/Contents/Versions/.../Google Chrome Helper.app/Contents/MacOS/../../../Google Chrome Framework.framework/Google Chrome Framework and /System/Library/Frameworks/WebKit.framework/Versions/A/Frameworks/WebCore.framework/Versions/A/WebCore.
