 433
 434         When a range's slider is being moved, we set SliderThumbElement's m_inDragMode flag
 435         to true and mark the range elements as the CapturingMouseEventsElement. When we get
 436         the mouseUp event, we are supposed to exit drag mode. However, when the range element
 437         gets disabled while dragging, we do not get the mouseUp event and we need to make
 438         sure we exit dragging mode anyway. r112547 tried to fix this by calling stopDragging()
 439         in SliderThumbElement::defaultEventHandler() when the input element is disabled.
 440         While this often works, this is fragile and we sometimes fail to exit dragging mode
 441         when we should.
 442
 443         This patch addressed the issue by calling stopDragging() in
 444         SliderThumbElement::disabledAttributeChanged() instead. This is much safer as we
 445         guarantee will exit dragging mode whenever the range element gets disabled, even
 446         if SliderThumbElement::defaultEventHandler() does not get called after that.

 895         Data interaction should register type identifiers in order of priority

 900
 901         Currently, due to the shared logic for writing to a UIPasteboard (in the case of copy/paste) and the shared
 902         UIItemProvider-based pasteboard wrapper (in the case of data interaction), we don't enforce any particular
 903         ordering in which type identifiers are registered in the generated item provider. This is because
 904         -[UIPasteboard setItems:] only takes an unordered mapping of type identifiers to objects.
 905
 906         To fix this, we introduce a separate way to set pasteboard data that first writes a list of object
 907         representations in order of priority (which is dependent on the content being interacted with) and then register
 908         individual type-data mappings at the end.
 909
 910         Augmented existing API tests in DataInteractionTests to check for the existence and priority of type identifiers
 911         in the UIItemProviders created upon starting data interaction. Also adds a new unit test:
 912         DataInteractionTests.TextAreaToInput.

1116         Start implementing the libgcrypt-based platform bits of CryptoKeyEC.
1117
1118         Implement keySizeInBits() by returning the appropriate size for this
1119         object's curve type. An assertion is added to ensure that this size
1120         matches the one that's returned by gcry_pk_get_nbits() for this
1121         object's EC key as represented by the m_platformKey gcry_sexp_t object.
1122
1123         Implement platformGeneratePair() by constructing a genkey s-expression
1124         that requests a generation of an EC key for the specified curve type.
1125         The s-expression is then passed to gcry_pk_genkey(), and the public
1126         and private key data is then retrieved from the returned s-expression
1127         upon success and used to create the public and private CryptoKeyEC
1128         objects.
1129
1130         The PlatformECKey type alias is changed to match gcry_sexp_t. The
1131         CryptoKeyEC destructor releases the gcry_sexp_t object through

1394
1395         While searching for mid-word break, we measure the text by codepoints in a loop until the accumulated width > available width.
1396         When we see that the accumulated width for the individual codepoints overflows, we join the codepoints and re-measure them.
1397         These 2 widths could be considerably different for number of reasons (ligatures is a prime example). When we figure that
1398         the run still fits, we go back to the main loop (since we are not supposed to wrap the line here) and take the next codepoint.
1399         However this time we start the measurement from the last whitespace, so we end up remeasuring a potentially long chuck of text
1400         until we hit the wrapping point. This is way too expensive.
1401         This patch changes the logic so that we just go back to measuring individual codepoints until we hit the constrain again.

1940
1941         The bug happens when drawing only a rectangle of an image not the whole
1942         image. In BitmapImage::draw(), sizeForDrawing was calculated as the destRect
1943         scaled by the transformation which is applied to the GraphicsContext. Two
1944         problems with this approach. The first one is destRect can be only part of
1945         the image. The second problem is, the ratio destRect / srcRect is another
1946         scaling that needs to be considered.
1947
1948         To fix this issue, first the base size has to be size of the image and not
1949         destRect.size(). Secondly, we need to scale this base size with the context
1950         transformation multiplied by the ratio destRect / srcRect. This scaling is
1951         exactly the same scaling which is calculated in subsamplingScale(). Finally
1952         we use this scaled size as the sizeForDrawing to send to the ImageDecoder.

2067
2068         Reviewed by David Hyatt.
2069
2070         The baseline-position syntax has changed recently, so we need to update
2071         the CSS properties using the old syntax. This patch address only the
2072         content-alignment (align-content and justify-content).
2073
2074         I used this patch to adapt the implementation of the parsing logic for
2075         these properties to the new Blink's CSS Parsing Design.
2076
2077         The new baseline syntax is "[first | last ]? baseline" which implies
2078         modifying the parsing and computed value logic.
2079
2080         There are several layout tests affected by this change, so I'll update
2081         them accordingly.
2082
2083         No new tests, just added/modified some cases to the tests we
2084         already have using the new baseline values.

2285         grids. This new API allows clients to set an arbitrary limit to the number of tracks. The
2286         addition of this new API forced us to add GridPosition.cpp to the project to define the
2287         global variable we use for testing. We took the chance to move part of the implementation
2288         from the header file to the source file.
2289
2290         Last but not least, several new ASSERTs were added to Grid.cpp implementation to ensure that
2291         we do not surpass the grid track limits.

2436         Reviewed by Simon Fraser.
2437
2438         TrueType GX-style variation fonts use one particular scale for values on their
2439         weight/width/slope axes - usually the values lie between -1 and 1 on that scale.
2440         However, OpenType 1.8-style fonts use the CSS scale for values on these axes.
2441         For the purposes of font selection, these values need to lie on the same scale.
2442         However, when font selection is completed and the variation values are actually
2443         being applied to the fonts, values which lie on the font's actual scale need to
2444         be applied. This patch adds normalize*() and denormalize*() functions to perform
2445         both of these operations.
2446
2447         The conversion itself between the two scales isn't an exact mapping. Mapping
2448         slope is just a linear relationship with 0deg <=> 0 and 20deg <=> 1 (as per the
2449         CSS Fonts spec). Mapping widths is similar, it uses a 2-component piecewise
2450         linear relationship which includes the values given in the Microsoft OpenType
2451         spec for the OS/2 table's usWidthClass field. Weights are more difficult, so I
2452         plotted the CSS weights and the GX-style weights for every style of San
2453         Francisco, saw that the relationship appears to be linear, and ran a linear
2454         regression to compute the line equation.
2455
2456         As for the actual discrimination of determining whether a font is a GX-style
2457         font or not, we can use the presence of the 'STAT' table. This table didn't
2458         exist when GX fonts were being created, and OpenType 1.8 variable fonts are
2459         required to have this table.
2460
2461         Facebook uses the string ".SFNSText" in their @font-face blocks. This font is
2462         a variation font, but uses the GX-style values. Facebook asks us to create
2463         this font with a weight of 700, and because the values in the font are around
2464         1.0, we were erroneously thinking that the font wasn't bold, so we were then
2465         applying synthetic bold. This was causing text on facebook to look fuzzy and
2466         ugly.

2508
2509         The baseline-position syntax has changed recently, so we need to update
2510         the CSS properties using the old syntax. This patch address only the
2511         self-alignment (align-self and justify-self) and default-alignment
2512         (align-items and justify-items).
2513
2514         The content-distribution properties (align-content and justify-content)
2515         will be updated in a follow up patch.
2516
2517         The new baseline syntax is "[first | last ]? baseline" which implies
2518         modifying the parsing and computed value logic.

2541
2542         Animated SVG images are not paused in pages loaded in the background. We rely
2543         on FrameView::isOffscreen() to stop images animations in background tab (See
2544         logic in RenderElement's shouldRepaintForImageAnimation()). This works fine
2545         if a tab is visble and then becomes hidden (i.e. by switching to another
2546         tab). However, in the case where the tab gets loaded while in the background
2547         (e.g. opening link in new background tab, or session restore), then the
2548         animations would not be paused, due to FrameView::isOffscreen() erroneously
2549         returning false in this case.
2550
2551         Normally, the following chain of events happens:
2552         - Page is visible, we construct a main frame and its FrameView for loading
2553           the page. When a FrameView is constructed, we call FrameView::show() to
2554           make it visible. Then, if the page becomes non-visible, we call
2555           Page::setIsVisibleInternal(false) which calls FrameView::hide(). After
2556           that, FrameView::isOffscreen() correctly returns true because we properly
2557           called FrameView::hide().
2558
2559         However, when doing a load while the Page is hidden, the following was
2560         happening:
2561         - Page is not visible, we call Page::setIsVisibleInternal(false) which tries
2562           to call FrameView::hide() for the main frame but it does not have a FrameView
2563           yet (because the load has not started). We start the load and end up creating
2564           a FrameView. The FrameView constructor was calling FrameView::show()
2565           unconditionally, thus making the FrameView think is visible, even though its
2566           page isn't. At this point, FrameView::isOffscreen() was returning false
2567           and animations would keep running, even though the page is not visible.
2568
2569         To address the issue, we now call FrameView::show() in FrameView::create() only
2570         if the Page is actually visible, instead of calling it unconditionally. If the
2571         page ever becomes visible, Page::setIsVisibleInternal(true) will be called and
2572         it will take care of calling FrameView::show() then.

2655
2656         We did some work in webkit.org/b/168751 to prevent the controls bar from disappearing while the
2657         captions menu is visible. But there were two cases where the behavior was not as intended:
2658
2659             1. the controls bar would hide upon exiting the video.
2660             2. clicking on the controls bar while the caption panel is up would hide the controls bar
2661                as well as the captions panel.
2662
2663         Instead of determining that the "userInteractionEnabled" property being set to "false" is indicative
2664         of secondary UI, such as the tracks panel, being attached to the controls bar, we now have an
2665         explicit property to specify this. Now, when "hasSecondaryUIAttached" is "true", we prevent the
2666         controls bar from fading when exiting the media.
2667
2668         Additionally, when dismissing the tracks panel, we check whether a mouse event lead to this and check
2669         if the mouse was positioned over the controls bar. If that is the case, we no longer hide the controls
2670         bar and only dismiss the tracks panel.

2692         after a commit, so we now override commit(). Otherwise, the <canvas> that we draw the volume slider

3080         Rewrite the network agent's command for disabling resource caching to use Page::setResourceCachingEnabled.
3081         The old implementation was doing weird stuff like setting no-cache headers and evicting the
3082         contents of the memory cache, neither of which is correct. The new approach has no side effects

3270         https://bugs.webkit.org/show_bug.cgi?id=169145
3271         <rdar://problem/17048858>
3272
3273         Reviewed by Dean Jackson.
3274
3275         There were a variety of issues with media documents, some longstanding, and some specifically
3276         about modern media controls.
3277
3278         One issue was that fullscreen and picture-in-picture buttons would show for audio media documents,
3279         due to using a <video> element to load the audio file. We now have additional logic in MediaController
3280         to identify if the loaded media is really an audio file, and using this information to hide the
3281         fullscreen and picture-in-picture buttons.
3282
3283         Another issue was that we would inject style in MediaDocument.cpp that was specific to modern media
3284         controls when we could have the modern-media-controls module injected CSS handle this styling. We now
3285         use the injected style in the shadow root to size media documents based on the device characteristics
3286         and ensuring that page styles are overridden.
3287
3288         We also simplify how MediaDocument.cpp sets the source of the media element to simply use the "src"
3289         attribute and not a <source> element.
3290
3291         Finally, we introduce a MediaDocumentController class that is instantiated when we're dealing with
3292         a media document to hide the controls while we determine the type of media we're loading (audio vs.
3293         video) in order to apply the appropriate styling without flashes.
3294
3295         As a result of the new styles applied by the modern-media-controls module, media documents have a
3296         similar behavior on macOS and iPad, where we only enforce a min-width for video allowing them
3297         to play at their natural size otherwise, and enforcing a fixed width for audio. On iPhone however,
3298         we want to always play the media at full width, with some padding in the case of audio.

3356         REGRESSION(213764): Large images should not be decoded asynchronously when they are drawn on a canvas
3357         https://bugs.webkit.org/show_bug.cgi?id=169771
3358
3359         Reviewed by Simon Fraser.
3360
3361         Sometimes we have to draw the image immediately like when a canvas calls
3362         drawImage. In this case we have to decode the image synchronously to guarantee
3363         the drawing. Other times we need to decode with the native size of the image.
3364         The animated images have to be decoded with native size always. Otherwise
3365         the frame cache will be messed up if the same image is animated with different
3366         sizes. Currently we always decode asynchronously with sizeForDrawing. We need
3367         to decouple the decoding mode from the sizeForDrawing.
3368
3369         This patch introduce the DecodingOptions class which can store and compare the
3370         following four cases:
3371             -- Synchronous: The frame has be decoded with native size only.
3372             -- Asynchronous + anySize: This is passed from the Image::draw() callers.
3373             -- Asynchronous + fullSize: The image has to be decoded with its full size.
3374             -- Asynchronous + sizeForDrawing: The image can be decoded with sizeForDrawing unless
3375             it was decoded with either a full size or sizeForDrawing which is larger than the
3376             requested sizeForDrawing.
3377
3378         A new argument of type DecodingMode will be added to Image::draw() function.
3379         Only when the drawing comes from the render tree, it will be Asynchronous.
3380         Otherwise it will be Synchronous.

3469         (WebCore::ImageFrameCache::requestFrameAsyncDecodingAtIndex): Call hasAsyncNativeImage() instead of hasValidNativeImage()
3470         Call frameIsDecodingCompatibleWithOptionsAtIndex() instead of frame.isBeingDecoded(). Replace the call to enqueueSizeForDecoding()
3471         by appending the same ImageFrameRequest to m_frameCommitQueue.
3472         (WebCore::ImageFrameCache::isAsyncDecodingQueueIdle): Use m_frameCommitQueue to answer the question whether the decodingQueue is idle.

3476         (WebCore::ImageFrameCache::singlePixelSolidColor): Don't cache the frame if it is an animated image or the size is not a single pixel.
3477         (WebCore::ImageFrameCache::frameIsBeingDecodedAndIsCompatibleWithOptionsAtIndex): Use m_frameCommitQueue to answer the question whether an ImageFrame
3478         is being decoded and is compatible with DecodingOptions.
3479         (WebCore::ImageFrameCache::frameHasFullSizeNativeImageAtIndex): Calls ImageFrame::hasFullNativeImage() for a frame.
3480         (WebCore::ImageFrameCache::frameHasDecodedNativeImageCompatibleWithOptionsAtIndex): Calls ImageFrame::hasDecodedNativeImageCompatibleWithOptions() for a frame.
3481         (WebCore::ImageFrameCache::frameImageAtIndex): Returns the current NativeImage without caching.
3482         (WebCore::ImageFrameCache::frameImageAtIndexCacheIfNeeded): Returns the current NativeImage but cache it synchronously if needed.

3488         (WebCore::ImageFrameCache::frameHasValidNativeImageAtIndex): Deleted.
3489         (WebCore::ImageFrameCache::frameHasDecodedNativeImage): Deleted.
3490         * platform/graphics/ImageFrameCache.h: Two ImageFrameRequest queues will be used.
3491         -- The existing one m_frameRequestQueue which is shared between the main thread and decoding thread. The requests will be
3492         dequeued from it before starting the decoding. The decoded NativeImage will be cached only on the main thread. The decoding
3493         thread is not blocked by the callOnMainThread(). This means there might be multiple ImageFrameRequests which were dequeued
3494         while their NativeImages have not been cached yet.
3495         -- A new one m_frameCommitQueue which is track all the ImageFrameRequests whose NativeImages have not been cached yet.
3496         (WebCore::ImageFrameCache::frameAtIndexCacheIfNeeded): Be explicit about caching the image frame. frameImageAtIndex()
3497         returns the current image frame without caching. frameAtIndexCacheIfNeeded(). returns the current image frame but cache
3498         it if needed.

3625
3626         Currently we block style and renderer building completely if document has any loading
3627         stylesheets. In case a script queries something layout dependent we construct the render
3628         tree with whatever style we have but block painting in it.
3629
3630         This patch changes behavior so that a loading stylesheet in body only blocks rendering for elements
3631         that are after it. The expectation is that such stylesheets rarely affect elements before them
3632         and the elements can be rendered without causing ugly visible styling changes.
3633
3634         The patch replaces the old flash-of-unstyled-content (FOUC) preventation mechanism with a more
3635         fine-grained one. Paint blocking is now done on per-renderer basis with based on isNonFinal flag in
3636         RenderStyle.
3637
3638         For stylesheets in head the behavior should be largely unchanged.

3982         but not synchronously like it used to.  This assertion is now invalid, but tests
3983         that would hit it still pass.
3984         * platform/network/cf/SocketStreamHandleImplCFNet.cpp:
3985         (WebCore::SocketStreamHandleImpl::platformSendInternal):
3986         CFWriteStreamCanAcceptBytes crashes if you give it a null parameter, and that can happen now.
3987         If we have no write stream, then we cannot write.  Tests that hit this pass still.
