Hi WebKitten, As I see the following codes and grep, I seem today's all (?) ports of WebKit have enabled ENABLE_STREAMS_API flag by default. - https://trac.webkit.org/browser/trunk/Source/WTF/wtf/PlatformEnable.h?rev=26... - https://trac.webkit.org/browser/trunk/Source/cmake/OptionsFTW.cmake?rev=2632... - https://trac.webkit.org/browser/trunk/Source/cmake/OptionsWin.cmake?rev=2632... - https://trac.webkit.org/browser/trunk/Source/cmake/OptionsMac.cmake?rev=2632... - https://trac.webkit.org/browser/trunk/Source/cmake/WebKitFeatures.cmake?rev=... - https://trac.webkit.org/browser/trunk/Source/cmake/tools/vsprops/FeatureDefi... If my assumption is right, I'd like to propose to remove this `ENABLE_STREAMS_API` flag. What do you think about this? If I missed some ports, please tell me about them. -- Tetsuharu OHZEKI tetsuharu.ohzeki@gmail.com
