1// http://dev.chromium.org/blink/runtime-enabled-features 2// 3// This list is used to generate RuntimeEnabledFeatures.h/cpp which contains 4// a class that stores static enablers for all experimental features. 5// 6// Each feature can be assigned a "status": 7// status=stable -> Enable this in all Blink configurations. We are committed to these APIs indefinitely. 8// status=experimental -> In-progress features, Web Developers might play with, but are not on by default in stable. 9// status=test -> Enabled in ContentShell for testing, otherwise off. 10// status=deprecated -> Alias for "test", will be removed at some point. 11// Features without a status are not enabled anywhere by default. 12// 13// "stable" features listed here should be rare, as anything which we've shipped stable 14// can have its runtime flag removed soon after. 15// 16// condition=ENABLE_NAME is used for wrapping features in compile-time 17// #if ENABLE(FEATURE) guards. These are deprecated and should all be removed. 18 19AnyPointerMediaQueries status=experimental 20ApplicationCache status=stable 21AudioVideoTracks depends_on=Media, status=experimental 22AuthorShadowDOMForAnyElement 23BackgroundSync status=experimental 24BatteryStatus status=stable 25Beacon status=stable 26 27// This feature is deprecated and we are evangalizing affected sites. 28// See https://crbug.com/346236 for current status. 29PrefixedVideoFullscreen status=stable 30 31// Enable bleeding-edge code to make Blink draw content faster. 32// The changes enabled behind this flag are very likely to break lots of content. 33// ** DO NOT use this flag unless you know what you are doing. ** 34BleedingEdgeFastPaths 35ThemeColor status=stable 36 37ClientHintsDpr status=experimental 38ContextMenu status=experimental 39Crypto status=stable 40CSSAnimationUnprefixed status=experimental 41CSSAttributeCaseSensitivity status=experimental 42CSSCompositing status=experimental 43CSSGridLayout status=experimental 44CSSMaskSourceType status=experimental 45CSSOMSmoothScroll status=experimental 46CSSTouchActionDelay status=test 47CSSViewport status=experimental 48CSS3Text status=experimental 49CSS3TextDecorations status=experimental 50CompositedSelectionUpdate 51CustomSchemeHandler depends_on=NavigatorContentUtils, status=experimental 52Database status=stable 53DecodeToYUV status=experimental 54DeviceLight status=experimental 55DisplayList2dCanvas 56SVGFontsOnNonGDIPlatforms 57EncodingAPI status=stable 58EncryptedMedia status=test 59EncryptedMediaAnyVersion status=stable 60ExecCommandInJavaScript status=test 61ExperimentalCanvasFeatures status=test 62ExperimentalContentSecurityPolicyFeatures status=experimental 63ExperimentalWebSocket status=stable 64FastMobileScrolling 65FileAPIBlobClose status=experimental 66FileConstructor status=stable 67FileSystem status=stable 68FullscreenUnprefixed status=test 69Gamepad status=stable 70Geofencing status=test 71GeometryInterfaces status=test 72IMEAPI status=experimental 73ImageDataConstructor status=experimental 74ImageRenderingPixelated status=experimental 75IndexedDBExperimental status=experimental 76InputModeAttribute status=experimental 77LangAttributeAwareFormControlUI 78LayerSquashing status=stable 79PrefixedEncryptedMedia status=stable 80LocalStorage status=stable 81Media status=stable 82MediaCapture 83MediaController depends_on=Media, status=experimental 84MediaSource status=stable 85MediaSourceExperimental depends_on=MediaSource, status=experimental 86MediaStream status=stable 87MemoryInfoInWorkers status=experimental 88NavigationTransitions status=experimental 89NavigatorContentUtils 90NetworkInformation status=stable 91Notifications status=stable 92OrientationEvent 93// Only enabled on Android, and for certain layout tests on Linux. 94OverlayFullscreenVideo 95PagePopup status=stable 96PathOpsSVGClipping status=stable 97PeerConnection depends_on=MediaStream, status=stable 98PreciseMemoryInfo 99Presentation status=test 100PushMessaging status=experimental 101QuotaPromise status=experimental 102OverlayScrollbars 103RegionBasedColumns status=experimental 104 105RequestAutocomplete status=test 106ScreenOrientation status=stable 107ScriptedSpeech status=stable 108 109// Implements documentElement.scrollTop/Left and bodyElement.scrollTop/Left 110// as per the spec, matching other Web engines. 111ScrollTopLeftInterop status=experimental 112ServiceWorker status=experimental 113// FIXME: When ServiceWorker is status=stable add a webexposed test to 114// verify that addEventListener('fetch', ... is *not* fired when 115// onfetch is not enabled. 116ServiceWorkerOnFetch status=experimental 117SessionStorage status=stable 118SharedWorker status=stable 119PictureSizes status=stable 120Picture status=stable 121 122// window.showModalDialog is deprecated and slated for removal. crbug.com/345831 123ShowModalDialog status=deprecated 124 125// Lax Mixed Content checking for WebSockets, XHR, etc. is deprecated and slated for removal. crbug.com/389089 126LaxMixedContentChecking status=deprecated 127 128Stream status=experimental 129SubpixelFontScaling status=stable 130SubresourceIntegrity status=test 131 132// Many websites disable mouse support when touch APIs are available.
