  80         getEditorCommandsForKeyEvent() renamed as commandsForKeyEvent(),
  81         since it now returns the list of commands to simplify the

 101         Refactor AudioContext implementation to enable automatic binding generation of promise-based methods
 102         https://bugs.webkit.org/show_bug.cgi?id=145223
 103
 104         Reviewed by Darin Adler.
 105
 106         Introducing DOMPromise as a typed wrapper above DeferredWrapper.
 107         This DOMPromise allows constraining Promise resolution/rejection to a single resolution type and rejection type.
 108         This might be useful for typed callback usage of promise based APIs, like getUserMedia() or ReadableStreamReader.read().
 109
 110         Applying DOMPromise to AudioContext close, suspend and resume.
 111         Changed binding code to represent what could be automatically generated by binding generator.
 112         Fixing unneeded copies of std::function callbacks.
 113
 114         Disabling DOMPromise copy constructors to lower chances that resolution/rejection is done twice on the same object.

 142
 143         Reviewed by Darin Adler
 144
 145         Introduced abstract ReadableStream::doPull() which is overriden in ReadableJSStream.
 146         Added support to call the "pull" JS callback in ReadableJSStream::doPull().
 147         Added calls to pull as requested by the spec (when resolving a read callback, at start time...).
 148
 149         Fixed issue in ReadableStreamReader::read() (use of successCallback(JSValue()) in lieu of endCallback())

 169         DeferredWrapper should clear its JS strong references once its promise is resolved/rejected
 170         https://bugs.webkit.org/show_bug.cgi?id=145753
 171
 172         Reviewed by Darin Adler.
 173
 174         Clear strong references at the end of DeferredWrapper::resolve and DeferredWrapper::reject.
 175         Added assertions to check that resolve or reject is called only once.
 176
 177         Removed DeferredWrapper constructor that creates internally its promise.
 178         Reason is DeferredWrapper can be resolved synchronously and promise
 179         will be lost when returning it at the end of the binding promise function.

 219         Protect FrameView from being destroyed in Document::recalcStyle()
 220         https://bugs.webkit.org/show_bug.cgi?id=143033
 221         rdar://problem/20326871
 222
 223         Reviewed by Andreas Kling.
 224
 225         This patch ensures that FrameView stays valid in Document::recalcStyle().
 226         It follows the defensive pattern we use to deal with the refcounted FrameView (see EventDispatcher::dispatchEvent)
 227
 228         When the iframe destroys itself in the onBeforeLoad callback (as the result of
 229         PostResolutionCallbackDisabler -> HTMLObjectElement::updateWidget -> guardedDispatchBeforeLoadEvent),
 230         we detach the frame and release the FrameView. However Document::recalcStyle() expects
 231         the FrameView to stay valid.

 240         3D-transformed video does not display on platforms without accelerated video rendering
 241         https://bugs.webkit.org/show_bug.cgi?id=144782
 242
 243         Reviewed by Simon Fraser.
 244
 245         Video element does not get GraphicsLayer when MediaPlayerPrivate::supportsAcceleratedRendering() returns false
 246         which means not using accelerated video decoding.
 247         Although the video element gets GraphicsLayer by changing the CSS style of video element by javascript,
 248         there is no way to set GraphicsLayer::setDrawsContent(true) for updating the video content.
 249         As a result, after changing the CSS style, the video content does not show.
 250         To avoid missing setDrawsContent(true), add conditions(!supportsAcceleratedRendering() && m_requiresOwnBackingStore).

 264
 265         The bug was caused by setSelection not updating RenderView when there is a style recalc scheduled

 310         Give the GraphicsContextState stack an inline capacity of 1, and make sure
 311         to free any heap-allocated backing store when the stack goes empty.
 312
 313         The 1 is because HTMLCanvasElement keeps one "save" on the underlying
 314         GraphicsContext at all times, and this prevents those canvases from always
 315         sitting on an empty stack with 16 capacity.

 325         SVG Fragment is not rendered if it is the css background image of an HTML element

 327
 328         Reviewed by Darin Adler.
 329
 330         To show an SVG fragment, the SVGImage has to scrollToFragment() using
 331         the resource url. The changes http://trac.webkit.org/changeset/164804
 332         and http://trac.webkit.org/changeset/164983 set the url of SVGImage to
 333         to be used later in SVGImage::draw(). The problem is the SVGImage url
 334         is only set when it is the src of an <img> tag. We did not do the same
 335         thing when the SVGImage is the css background image of an HTML element.
 336
 337         The fix is to set the url of the SVGImage always when it's created by
 338         the CachedImage. The CachedImage must have a valid url when the SVGImage

 523
 524         Reviewed by Antti Koivisto.
 525
 526         At some point, someone who didn't understand JSValue very well added checks for
 527         isEmpty (and the function isEmpty itself) in JavaScript bindings. But the engine
 528         never would pass an empty JSValue to a binding; that's used only inside the
 529         engine itself. I think this was done by some Google V8 experts a while back, so
 530         it's not entirely surprising they didn't understand this. But we don't want to
 531         keep all that unneeded code.
 532
 533         * bindings/js/JSAudioTrackCustom.cpp:
 534         (WebCore::JSAudioTrack::setKind): Removed the isEmpty clause here. I presume this
 535         was copied and pasted from script-generated bindings. While I was at it, I used a
 536         slightly more efficient code path that avoids doing a ref/deref on the string by
 537         using auto&. That's trickier to do correctly for functions with more than one
 538         argument, so I didn't do it in the bindings generator yet.
 539         (WebCore::JSAudioTrack::setLanguage): Ditto.

 547         * bindings/scripts/CodeGeneratorJS.pm:
 548         (GenerateImplementation): Use "=" syntax instead of constructor style syntax for
 549         the argument processing. I think this is more readable.
 550         (GenerateParametersCheck): For the enum code path, did the more efficient auto&
 551         idiom to avoid ref/deref on a string. For the toExistingAtomicString path,
 552         restructured so we don't have to check the flag indicating that something is atomic.
 553         Later we could also avoid the ref/deref; added a FIXME about that.
 554         (GetNativeType): Use String, not const String, for local variables. Sure, the
 555         string is const, but so is every other local variable type we use! No need to be
 556         wordy about it.
 557         (JSValueToNative): Removed the uneeded calls to isEmpty. Since the call sites no
 558         longer use construction syntax, used initializer syntax style for a couple classes
 559         that are constructed with multiple arguments.

 717         Fixes an issue where a click event was dispatched to a shadow tree node regardless of whether
 718         both the mouse press and mouse release were targeted at it. In particular, releasing the mouse
 719         on the AutoFill button activates it regardless of whether the mouse was pressed on it.
 720
 721         Currently we always dispatch a click event to a node n where the mouse was released when n is
 722         in a shadow tree regardless of whether the mouse was pressed on n. Instead we should only
 723         dispatch a click event to n if the mouse was pressed and released on n. If n is a shadow tree
 724         descendant, the mouse was released on n, and n never received a mouse press then we should
 725         dispatch the click event at the shadow host element of n to preserve the illusion to web

 743
 744         We would sometimes crash when pruning the PageCache because it was
 745         possible for frames to still be loading while in the PageCache and
 746         we would try to stop the load when the CachedFrame is destroyed. This
 747         code path was not supposed to be exercised as we were not supposed to
 748         have pages still loading inside the PageCache.
 749
 750         r185017 made sure we don't insert into the PageCache pages that are
 751         still loading. However, nothing was preventing content from starting
 752         new loads in their 'pagehide' event handlers, *after* the decision
 753         to put the page in the PageCache was made.
 754
 755         This patch prevents content from starting loads from a 'pagehide'
 756         event handler so that we can no longer have content that is loading
 757         inside the PageCache. 'ping' image loads still go through though as
 758         these are specially handled and use PingLoaders.

 777         The wrapper takes care of updating the m_dismissalEventBeingDispatched
 778         member on the Page every time the member on FrameLoader is updated. We
 779         now cache this information on the Page so that clients can cheaply
 780         query if a dismissal event is being dispatched in any of the Page's
 781         frame, without having to traverse the frame tree.

 791         made the decision to add the Page to the PageCache.

 816         Add a m_dismissalEventBeingDispatched member to the Page so that we can
 817         easily query if a dismissal event is being dispatched in any of the
 818         frames, without having to traverse the frame tree. I suspect more call
 819         sites of FrameLoader::pageDismissalEventBeingDispatched() may actually
 820         want this but I did not make such change in this patch. It is important
 821         to check all the frames and not simply the current one because a frame's
 822         pagehide event handler may trigger a load in another frame.

1052
1053         No new tests, because it's hard to test whether a DNS request has been sent. We could do
1054         this by adding new API to modify the GProxyResolver and GResolver used by the SoupSession in
1055         the network process, but even if such API were desirable, it would be a big job. Tests
1056         should not be allowed to dictate our public API.

1303         This can get extremely expensive, especially on low-memory devices.
1304         This patch makes WebKit stop handing out compositing layers for this kinda thing:

1343
1344         Limit the number of vnodes used by the WebContent processes to reduce
1345         the chance of getting killed due to the system running out of vnodes.
1346         We sometimes see the WebContent process use up to 50% of the system's
1347         vnode limit on some tests on iOS, which seems excessive. Most vnodes
1348         are due to CachedResources which are mmap'd from the WebKit disk cache
1349         and kept alive due to caches such as the Memory Cache / PageCache.
1350
1351         This patch adds tracking for the number of SharedBuffer objects that are
1352         backed by a CFDataRef as this should track most of the vnodes used by
1353         the process. The WebContent process registers a vnode pressure handler
1354         upon initialization (likely it already does for memory pressure
1355         handling). This handler gets called when the process uses over 15% of
1356         of system's vnode limit and the "critical" flag is set if it uses over
1357         20% of the system limit. The vnode pressure handler currently calls the
1358         memory pressure handler as freeing our caches (especially PageCache,
1359         MemoryCache) and doing a JS GC frees up vnodes.
1360
1361         On iPhone 6 Plus, the system limit is at 3000, which would lead to the
1362         following limits being used:
1363         soft: 450 / hard: 600
1364
1365         However, on older hardware, the system limit can be as low as 2000,
1366         which would lead to the following limits being used:
1367         soft: 300 / hard: 400
1368
1369         vnode tracking is currently only enabled on iOS because system vnode
1370         limits are usually much higher on Mac (e.g. 473695 on Mac Pro, 9984
1371         on a 2011 MacBook Air) and we normally don't get killed.

1418
1419         On WK1, the NSView we use for NSButtonCells is parented in the ScrollView.
1420         Our checkbox and radiobutton animations cause AppKit to create a CALayer which
1421         is parented into that view. As we render the animations, we see the CALayer getting
1422         drawn also.
1423
1424         The fix was to use an unparented layer on WK1 when drawing these controls, the same
1425         way WK2 does. This technique may apply to all controls, but restricting it
1426         to just the buttons at the moment is less risky.
1427

1499
1500         In WebKit, we first lay out lines, and then we lay out text inside those lines. Text is vertically centered in
1501         its containing line. If the author has not specified a particular line-height, the height of a line comes from
1502         the font metrics for the primary font of the line.
1503
1504         In iOS, we were specifically hardcoding the line height metric of Apple Color Emoji to be 0. This means that,
1505         if Apple Color Emoji is the primary font for a line, and an explicit line-height was not specified, the lines
1506         are laid out with 0 height. Then, when we vertically center the text inside the line, the top half of the text
1507         overlaps the preceeding line.
1508
1509         I'm not sure exactly why were were hardcoding this value to 0, as it is surely wrong. I'm going to ask Enrica
1510         to review this patch; hopefully she knows the answer.

1913         If a transition is running on a pseudo-element, and the host element is removed
1914         from the DOM just as the transition ends, and there is a transition event listener,
1915         then we'd crash with a null dereference in event dispatch code.

1917         AnimationController tries to clean up running animations when renderers are destroyed,
1918         but omitted to remove the element from two vectors that store element references.
1919         Elements are only added to these vectors briefly on animation end, before firing
1920         events, but failure to remove the vector entries could result in attempting
1921         to fire an event on a pseudo-element with no host element.
1922
1923         Also convert EventDispatcher code to be more robust to potentially null event
1924         targets, since it's not clear that eventTargetRespectingTargetRules() can always

2029         Combine tiny DFAs into slightly larger ones
2030         https://bugs.webkit.org/show_bug.cgi?id=145572
2031
2032         Reviewed by Alex Christensen.
2033
2034         This patch changes the ContentExtensions compiler to combine tiny DFA
2035         until they reach a minimum size.
2036
2037         The main tool introduced here is DFAMerger. It combines 2 DFAs into
2038         a single DFA that represent the union of the two machines.
2039         That is done by a simple subset construction on the "name" of the nodes
2040         in each DFAs.
2041
2042         Since we only merge 2 machines, and they are both deterministic, we know that
2043         we can only be in one state of each machine, or a state in one machine without
2044         equivalent in the other machine.
2045         We exploit that to identify the mapping between nodes. To identify a node in
2046         the new machine from nodes in the original machines, we just concatenate the node
2047         IDs into a single 64 bits number. If there is no node in one of the machine, we
2048         use a special tag.
2049
2050         The current algorithm does not have any subgraph pruning, machines grow very very
2051         quickly. Because of that, we only merge very small DFAs at the moment.

2244         Prune more resources from the MemoryCache before process suspension or
2245         on simulated memory warning by doing a synchronous JS garbage collection
2246         and sweep *before* pruning dead resources from the memory cache.
2247         Previously, we would do the garbage collection after pruning the
2248         MemoryCache which meant that a lot of resources became dead after we
2249         tried to prune them.
2250
2251         At the end a basic browsing on apple.com, we are able to remove ~17%
2252         more resources from the MemoryCache on simulated memory warning with this
2253         change.
2254
2255         Pruning as much as we can from the memory cache on critical memory
2256         pressure or before process suspension is not only useful to free up
2257         memory but also to make room in the vnode table as a lot of
2258         CachedResources are mmmap'd from the network disk cache.

2288         way, we no longer need to do a sync GC after calling the memory pressure

2340
2341         This page revealed a bug in our RenderBox code caused by the mismatch between
2342         our scrolling units, which are all integrally snapped, with our client height
2343         and widths, which are not snapped at all.
2344
2345         In certain cases, the client height would have a small subpixel difference compared
2346         to the scroll height, which would cause WebKit to believe it was scrollable. When

2364         [Cocoa] Clean up m_font inside FontPlatformData

2366
2367         Reviewed by Andreas Kling.
2368
2369         FontPlatformDatas are used as keys in a HashMap. This means that they need
2370         to be able to represent a "deleted" value. Previously, this "deleted" value
2371         was represented as setting the pointer value of m_font to -1, and guarding
2372         all uses of m_font to make sure it wasn't -1 before dereferencing it.
2373
2374         This patch simplifies FontPlatformData to represent a "deleted" value using
2375         a separate boolean member variable. This class is already big enough that
2376         the increased space is negligable (the class already contains two CoreText
2377         fonts in addition to a CoreGraphics font). Because of this simplification,
2378         m_font can now be a RetainPtr, instead of being manually retained and
2379         released.
2380
2381         There is still a long way to go before FontPlatformData is acceptably
2382         clean and understandable. This patch improves one aspect of it, and more

2862         <rdar://problem/20966828>

2864         Reviewed by Simon Fraser.
2865
2866         Tested by platform/mac-wk2/tiled-drawing/scrolling/fast-scroll-iframe-latched-select.html
2867
2868         When the scroll gesture is started when the latched scrollable container is not at the limit of its
2869         scroll region, we are NOT supposed to propagate the scroll event to the enclosing region. However,
2870         we were doing two things wrong:
2871         (1) When we recognized we were latching, we were using the right wheel event target, but not using
2872             the latched scrollable container.
2873         (2) Likewise, we were not using latched ScrollableArea when handling wheel events.
2874
2875         Instead, we were using the current scrollable container and ScrollableArea under the mouse pointer,
2876         which could be different from the point we started latching as the content scrolled.
2877
2878         The fix was to properly track the scrollable container and scrollable area during latching.
2879
2880         I attempted to store the latched ScrollableArea in the latchingState object, like we already do for the
2881         scrollable container, but found that this did not work properly. I think the life cycle of the
2882         ScrollableArea may not match the scrollable container, and since they are not reference counted I
2883         simply retrieve the ScrollableArea when needed.

2890         ContainerNode. When latching, make sure to use the ScrollableArea that is related to the latched scrollable
2891         container, not the area currently underneath the mouse pointer.

2905         Before 183498, callers of FrameLoader::changeLocation() got automatically assigned a frame name of "_self".
2906         After 183498, many remained without a frame name.
2907
2908         Later on, FrameLoader applies the <base> target as their frame name if they don't already have one.
2909
2910         When the <base> target is "_blank", that causes a new window/tab.
2911
2912         Restoring "_self" to these call sites fixes this.

2942         The composited layer always snaps to an enclosing device pixel (floors) while the renderer rounds.
2943         At certain positions (for example 0.5px on a 1x display), a gap is formed between the layer(0px) and its renderer(1px).
2944         In such cases, when the the renderer moves to a position (1.1px) where the gap is closed, we need to issue repaint on the layer

3239         Only call FrameView::viewportContentsChanged() after a style recalc if
3240         composited layers have been updated (and there is no pending layout).
3241
3242         We already viewportContentsChanged() after layout so we only need to
3243         call viewportContentsChanged() after a style recalc if it did not cause
3244         a layout but may have caused an element to become visible. In
3245         particular, this can happen in the case of composited animations (e.g.
3246         using -webkit-transform to move an element inside the viewport).
3247         Therefore, we now only call viewportContentsChanged() after a style
3248         recalc if it caused composited layers to be updated. This avoids a lot
3249         of unnecessary calls to viewportContentsChanged(), which is expensive.

3397
3398         The "should open external URLs" flag is only for main frames.
3399         It doesn't enforce any sort of policy internal to WebKit, but rather is for notifications to the policy delegate.
3400
3401         It is set from one of two places:
3402         1 - A main frame is navigated by any frame as the result of a user gesture.
3403         2 - WebKit2 API explicitly states the flag is true.
3404
3405         The flag value propagates when:
3406         1 - When a main frame document is navigated to a new main frame document.
3407         2 - When a new window is opened from a page whose main frame had the flag set.
3408         3 - When a new window is opened as the result of a user gesture.
3409
3410         The flag resets to false when:
3411         1 - A subframe navigates a main frame without a user gesture.
3412
3413         This patch is large, but does little more than the following:
3414         1 - Adds a ShouldOpenExternalURLs flag to both FrameLoadRequest and NavigationAction.
3415         2 - Makes sure anybody who creates either of those objects sets a sensible for that flag.
3416         3 - When FrameLoader creates a new DocumentLoader, it sets its flag based on whether or not the load is in a main frame,
3417             whether or not the load is from a user gesture, and based on the initiator's value of the flag.

3825         Inform the editor client that we began editing when a text field is focused either
3826         by being explicitly focused (programmatically or by user interaction) or implicitly
3827         focused when the window became active.
3828
3829         Currently we only notify the editor client that we began editing a text field when
3830         when a person actually changes the value of the field. And we always notify the
3831         client that we ended editing when a text field is defocused regardless of whether
3832         we executed a began editing callback. Moreover we notify a client that we
3833         ended editing when the field is defocused (either explicitly or implicitly when the
3834         window becomes inactive). Instead we should always notify the client that we began
3835         editing when the field is focused so that this callback is symmetric with the end
3836         editing callback.

3953
3954         There was an assertion in MemoryCache::revalidationSucceeded() making
3955         sure that the resource that was revalidated is still in the memory
3956         cache. However, nothing prevents this resource from being pruned while
3957         it is being revalidated. We do make sure that the resource in question
3958         cannot be destroyed though (see CachedResource::canDelete()).
3959
3960         This patch gets rid of this assertion as it is incorrect. Also, the
3961         fact that the resource is no longer in the memory cache is not an
3962         issue. We are merely going to call MemoryCache::remove() to remove
3963         it from the memory cache before re-adding it and updating its
3964         HTTP response. The call to MemoryCache::remove() will simply be a
3965         no-op in this case and we will not have any problem adding the
3966         resource back to the memory cache because the resource is kept alive.
