   8         Return Ref instead of PassRefPtr in create() factory functions in css,
   9         because the factory can't return null.

 192
 193         If a transition is running on a pseudo-element, and the host element is removed
 194         from the DOM just as the transition ends, and there is a transition event listener,
 195         then we'd crash with a null dereference in event dispatch code.
 196
 197         AnimationController tries to clean up running animations when renderers are destroyed,
 198         but omitted to remove the element from two vectors that store element references.
 199         Elements are only added to these vectors briefly on animation end, before firing
 200         events, but failure to remove the vector entries could result in attempting
 201         to fire an event on a pseudo-element with no host element.
 202
 203         Also convert EventDispatcher code to be more robust to potentially null event
 204         targets, since it's not clear that eventTargetRespectingTargetRules() can always
 205         manage to return a non-null node.
 206
 207         Hard to make a test because this is timing sensitive.

 309         Combine tiny DFAs into slightly larger ones
 310         https://bugs.webkit.org/show_bug.cgi?id=145572
 311
 312         Reviewed by Alex Christensen.
 313
 314         This patch changes the ContentExtensions compiler to combine tiny DFA
 315         until they reach a minimum size.
 316
 317         The main tool introduced here is DFAMerger. It combines 2 DFAs into
 318         a single DFA that represent the union of the two machines.
 319         That is done by a simple subset construction on the "name" of the nodes
 320         in each DFAs.
 321
 322         Since we only merge 2 machines, and they are both deterministic, we know that
 323         we can only be in one state of each machine, or a state in one machine without
 324         equivalent in the other machine.
 325         We exploit that to identify the mapping between nodes. To identify a node in
 326         the new machine from nodes in the original machines, we just concatenate the node
 327         IDs into a single 64 bits number. If there is no node in one of the machine, we
 328         use a special tag.
 329
 330         The current algorithm does not have any subgraph pruning, machines grow very very
 331         quickly. Because of that, we only merge very small DFAs at the moment.

 521
 522         Reviewed by Andreas Kling.
 523
 524         Prune more resources from the MemoryCache before process suspension or
 525         on simulated memory warning by doing a synchronous JS garbage collection
 526         and sweep *before* pruning dead resources from the memory cache.
 527         Previously, we would do the garbage collection after pruning the
 528         MemoryCache which meant that a lot of resources became dead after we
 529         tried to prune them.
 530
 531         At the end a basic browsing on apple.com, we are able to remove ~17%
 532         more resources from the MemoryCache on simulated memory warning with this
 533         change.
 534
 535         Pruning as much as we can from the memory cache on critical memory
 536         pressure or before process suspension is not only useful to free up
 537         memory but also to make room in the vnode table as a lot of
 538         CachedResources are mmmap'd from the network disk cache.

 546         - Move here code from in the Cocoa handler that is doing a JS garbage
 547           collection as well as a sweep, and make this code cross-platform.

 559         (WebCore::MemoryPressureHandler::platformReleaseMemory):
 560
 561         Remove iOS-specific code that was doing a JS garbage collection and

 563
 564         (WebCore::MemoryPressureHandler::install):

 568         way, we no longer need to do a sync GC after calling the memory pressure
 569         handler. This avoids code duplication and makes sure the GC is done
 570         before pruning the memory cache.

 578         Reviewed by Andreas Kling.
 579
 580         m_isEmoji used to be a public member variable only defined on iOS. This
 581         means that, whenever it was consulted, the sites were surrounded by
 582         PLATFORM(IOS) guards. A cleaner design is to use a getter and setter,
 583         which on non-iOS platforms, always return false / do nothing. Then, the
 584         use sites can just use these functions without having ugly guards.

 620
 621         This page revealed a bug in our RenderBox code caused by the mismatch between
 622         our scrolling units, which are all integrally snapped, with our client height
 623         and widths, which are not snapped at all.
 624
 625         In certain cases, the client height would have a small subpixel difference compared
 626         to the scroll height, which would cause WebKit to believe it was scrollable. When
 627         this happened, it would get stuck latched to this element and block scrolling events.

 644         [Cocoa] Clean up m_font inside FontPlatformData
 645         https://bugs.webkit.org/show_bug.cgi?id=145634
 646
 647         Reviewed by Andreas Kling.
 648
 649         FontPlatformDatas are used as keys in a HashMap. This means that they need
 650         to be able to represent a "deleted" value. Previously, this "deleted" value
 651         was represented as setting the pointer value of m_font to -1, and guarding
 652         all uses of m_font to make sure it wasn't -1 before dereferencing it.
 653
 654         This patch simplifies FontPlatformData to represent a "deleted" value using
 655         a separate boolean member variable. This class is already big enough that
 656         the increased space is negligable (the class already contains two CoreText
 657         fonts in addition to a CoreGraphics font). Because of this simplification,
 658         m_font can now be a RetainPtr, instead of being manually retained and
 659         released.
 660
 661         There is still a long way to go before FontPlatformData is acceptably
 662         clean and understandable. This patch improves one aspect of it, and more
 663         improvements will eventually follow.

1147
1148         When the scroll gesture is started when the latched scrollable container is not at the limit of its
1149         scroll region, we are NOT supposed to propagate the scroll event to the enclosing region. However,
1150         we were doing two things wrong:
1151         (1) When we recognized we were latching, we were using the right wheel event target, but not using
1152             the latched scrollable container.
1153         (2) Likewise, we were not using latched ScrollableArea when handling wheel events.
1154
1155         Instead, we were using the current scrollable container and ScrollableArea under the mouse pointer,
1156         which could be different from the point we started latching as the content scrolled.
1157
1158         The fix was to properly track the scrollable container and scrollable area during latching.
1159
1160         I attempted to store the latched ScrollableArea in the latchingState object, like we already do for the
1161         scrollable container, but found that this did not work properly. I think the life cycle of the
1162         ScrollableArea may not match the scrollable container, and since they are not reference counted I
1163         simply retrieve the ScrollableArea when needed.

1171         container, not the area currently underneath the mouse pointer.

1185         Before 183498, callers of FrameLoader::changeLocation() got automatically assigned a frame name of "_self".
1186         After 183498, many remained without a frame name.
1187
1188         Later on, FrameLoader applies the <base> target as their frame name if they don't already have one.
1189
1190         When the <base> target is "_blank", that causes a new window/tab.
1191
1192         Restoring "_self" to these call sites fixes this.

1222         The composited layer always snaps to an enclosing device pixel (floors) while the renderer rounds.
1223         At certain positions (for example 0.5px on a 1x display), a gap is formed between the layer(0px) and its renderer(1px).
1224         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

1519         Only call FrameView::viewportContentsChanged() after a style recalc if
1520         composited layers have been updated (and there is no pending layout).
1521
1522         We already viewportContentsChanged() after layout so we only need to
1523         call viewportContentsChanged() after a style recalc if it did not cause
1524         a layout but may have caused an element to become visible. In
1525         particular, this can happen in the case of composited animations (e.g.
1526         using -webkit-transform to move an element inside the viewport).
1527         Therefore, we now only call viewportContentsChanged() after a style
1528         recalc if it caused composited layers to be updated. This avoids a lot
1529         of unnecessary calls to viewportContentsChanged(), which is expensive.

1677
1678         The "should open external URLs" flag is only for main frames.
1679         It doesn't enforce any sort of policy internal to WebKit, but rather is for notifications to the policy delegate.
1680
1681         It is set from one of two places:
1682         1 - A main frame is navigated by any frame as the result of a user gesture.
1683         2 - WebKit2 API explicitly states the flag is true.
1684
1685         The flag value propagates when:
1686         1 - When a main frame document is navigated to a new main frame document.
1687         2 - When a new window is opened from a page whose main frame had the flag set.
1688         3 - When a new window is opened as the result of a user gesture.
1689
1690         The flag resets to false when:
1691         1 - A subframe navigates a main frame without a user gesture.
1692
1693         This patch is large, but does little more than the following:
1694         1 - Adds a ShouldOpenExternalURLs flag to both FrameLoadRequest and NavigationAction.
1695         2 - Makes sure anybody who creates either of those objects sets a sensible for that flag.
1696         3 - When FrameLoader creates a new DocumentLoader, it sets its flag based on whether or not the load is in a main frame,
1697             whether or not the load is from a user gesture, and based on the initiator's value of the flag.

2105         Inform the editor client that we began editing when a text field is focused either
2106         by being explicitly focused (programmatically or by user interaction) or implicitly
2107         focused when the window became active.
2108
2109         Currently we only notify the editor client that we began editing a text field when
2110         when a person actually changes the value of the field. And we always notify the
2111         client that we ended editing when a text field is defocused regardless of whether
2112         we executed a began editing callback. Moreover we notify a client that we
2113         ended editing when the field is defocused (either explicitly or implicitly when the
2114         window becomes inactive). Instead we should always notify the client that we began
2115         editing when the field is focused so that this callback is symmetric with the end
2116         editing callback.

2233
2234         There was an assertion in MemoryCache::revalidationSucceeded() making
2235         sure that the resource that was revalidated is still in the memory
2236         cache. However, nothing prevents this resource from being pruned while
2237         it is being revalidated. We do make sure that the resource in question
2238         cannot be destroyed though (see CachedResource::canDelete()).
2239
2240         This patch gets rid of this assertion as it is incorrect. Also, the
2241         fact that the resource is no longer in the memory cache is not an
2242         issue. We are merely going to call MemoryCache::remove() to remove
2243         it from the memory cache before re-adding it and updating its
2244         HTTP response. The call to MemoryCache::remove() will simply be a
2245         no-op in this case and we will not have any problem adding the
2246         resource back to the memory cache because the resource is kept alive.

2280

2282
2283         The interface of GridResolvedPosition is full of static methods
2284         that are used only internally, we should not expose them.
2285
2286         Apart from that resolveGridPositionsFromStyle() do always return
2287         a valid GridSpan from now on meaning that the caller has to ensure
2288         that the resolution does not require running the auto-placement
2289         algorithm. A new class called GridUnresolvedSpan was added for
2290         that purpose.

2448
2449         Have GraphicsLayerCA plumb the current contents scale through to TileController::adjustCoverageRect()
2450         instead of TileController getting it from TileGrid.
2451
2452         This avoids a situation where adjustCoverageRect() could cause temporarily oversized tiling coverage
2453         if called while TileGrid's content scale is outdated, and we're neither zooming or pinching, following
2454         a pinch zoom that increased the scale factor.
2455
2456         Specifically, if all the velocity data is zero, we pad the coverage rect by a horizontal and vertical
2457         margin computed like so:
2458
2459             margin = defaultTileSize / tileGrid.scale
2460
2461         If the actual scale is 5, but the TileGrid's outdated scale is e.g 0.8, you'll get a much larger
2462         margin than you really wanted. Then the whole thing gets scaled up by 5x later on, and we explode
2463         in a fiery feast of IOSurface allocations.

2478
2479         No new tests (Fixing the four broken ones should suffice).
2480
2481         The bug was that evaluating arguments in a method/constructor call has no guaranteed sequencing.
2482
2483         Clang seems to always do LTR, allowing the PassRefPtr to be evaluated as a bool in the call to
2484         navigationType() before it is "consumed" by the PassRefPtr argument.
2485
2486         In Visual Studio the PassRefPtr consumption happened before the bool evaluation, meaning `false`
2487         was always passed in to navigationType(), breaking the four tests.
2488
2489         The fix? Using PassRefPtr here was silly in the first place.

2605         This patch ensures that overlap testing for composited layers works properly when the sibling
2606         layer gets composited through its child.
2607
2608         When a layer gets composited through its child content, the recursive overlap testing should build up the
2609         overlapmap stack so that sibling content is intersected both against the child and its parent bounds.

2635
2636         We sometimes crash when destroying a PageCache CachedFrame because its
2637         DocumentLoader is still loading. This should never happen as we are not
2638         supposed to let pages are still have pending loads into the PageCache.
2639
2640         However, we were using DocumentLoader::isLoadingInAPISense() as check
2641         in PageCache::canCachePageContainingThisFrame() which is not exactly
2642         what we want. isLoadingInAPISense() no longer considers subresource
2643         loads once the frame as loaded. This means if the JS triggers a new
2644         load in a subframe after it has been loaded, then isLoadingInAPISense()
2645         will return false, despite the pending load.
2646
2647         This patch replaces the isLoadingInAPISense() check with isLoading()
2648         as this will consider all pending loads, even after the frame is
2649         loaded.
2650
2651         In most cases, using isLoadingInAPISense() was not an issue because
2652         we call DocumentLoader::stopLoading() in all subframes before starting
2653         a provisional load. However, nothing seems to prevent JS from
2654         triggering a new load after that and before the new load gets committed
2655         (which is when we save the page into PageCache).
2656
2657         No new test as we don't have a reliable reproduction case and the
2658         issue is timing related.

2670         Consider throttling DOM timers in iframes outside the viewport

2675
2676         Throttle DOM timers in iframes that are outside the viewport to decrease
2677         CPU usage, improve performance and reduce power use.
2678
2679         The approach is similar to what we already did for requestAnimationFrame
2680         in r183998.
2681
2682         We already has support for throttling DOM timers at:
2683         - Page level: for backgound pages
2684         - DOM timer level: for timers changing the style of an element outside
2685           the viewport or drawing on a canvas outside the viewport.
2686
2687         This patch adds support for throttling DOM timers at Document level so
2688         we can throttle all timers inside a specific iframe / Document. It relies
2689         on the same timerAlignmentInterval that is used for throttling at Page
2690         level with tweaks so that different Documents inside the same Page can
2691         have a different timerAlignmentInterval.

2704         not be throttled so I got rid of this behavior. I don't see any reason
2705         why we would not throttle a timer simply because it is supposed to have

3049         Since the coverage rect of a newly-constructed GraphicsLayerCA is always empty,
3050         there's no way that the layer's own bounding box can intersect with it.
3051         Hence the m_intersectsCoverageRect flag should be false after construction.
3052
3053         This fixes an issue where compositing layers in subframes would be marked as
3054         non-volatile, despite being far outside the viewport and coverage rect.

3141
3142         WebKit uses some strings which contain the lower 8-bits of UTF-16 (thereby saving space). However,
3143         ICU doesn't understand this encoding. When we want to use ICU functions with strings in this encoding,
3144         we create a UTextProvider which converts our encoded strings to UTF-16 for ICU, one chunk at a time.
3145         This object contains a vtable which we populate to perform the conversion.
3146
3147         The WebKit function which actually returns the UTF-16 chunks has two relevant arguments: an index into
3148         the encoded string which ICU is requesting, and a direction from that index which ICU is interested
3149         in. This function populates a "chunk" which is characterized by a pointer to a buffer, the length of
3150         the populated data in the buffer, and an offset into the chunk which represents the index that the
3151         requested character was put into.
3152
3153         When ICU requests data going backward, we fill in the chunk accordingly, with the requested character
3154         all the way at the end. We then set the offset equal to the length of the buffer. However, this length
3155         value is stale from the previous time the function ran. Therefore, ICU was reading the wrong index in
3156         the chunk when expecting the requested character.

3178
3179         Reviewed by Darin Adler.
3180
3181         There should be eight TextFlows. A TextFlow consists of two directions.
3182         The first one controls the inline growing direction and the second one
3183         controls the block growing direction. We are going to use the cardinal
3184         directions to define these combinations.
3185
3186         We need to extract the following information easily from the TextFlow
3187
3188         -- isTextFlowReversed() // RTL
3189         -- isTextFlowFlipped()  // the opposite direction to normal
3190         -- isTextFlowVertical() // The line grows vertically
3191
3192         Mixing WritingMode and TextDirection into TextFlow and choosing their values
3193         carefully to ease implementing the above functions can make things clearer.

3299
3300         Updated code generator to generate the necessary declarations (constructor property in the prototype, the constructor class).
3301         In the case of CustomConstructor with NoInterfaceObject, the implementation of the constructor property related JS function is changed as follow:
3302         It creates a constructor object and shadows the constructor property JS function with this object.
3303         This ensures that only one constructor object is created per prototype.
3304         The constructor is not exposed as it is not added to the global object constructor map.
3305
3306         NoInterfaceObject is asking to not make the interface visible, which is contradictory with having a visible constructor of the interface.
3307         The case for having NoInterfaceObject and CustomConstructor is the following:
3308         We do not want to expose the interface but we still want to have a constructor property on the prototype of objects implementing the interface.
3309         One such case is https://streams.spec.whatwg.org/#globals

3363         [iOS] When viewing an MJPEG stream as the main resource, only the first
3364         frame paints
3365
3366         <https://bugs.webkit.org/show_bug.cgi?id=145185>
3367         <rdar://problem/20124694>
3368
3369         This bug is caused by state not being restored between successive loads
3370         of multipart/x-mixed-replace content. Each part of the stream is not
3371         treated as a wholly new load, so if state is cleared as part of the
3372         previous page being destroyed, it may not be restored when loading
3373         the next stream part.
3374
3375         On WK1, tile cache updates are disabled in FrameView::clear(), which is
3376         called as the previous page is destroyed, but were not being
3377         reenabled when loading new replacement content from the stream.
3378
3379         On WK2, the exposed content rect was being reset to an empty rect as
3380         the previous page was destroyed, but it was not being reset by loading
3381         replacement content.
3382
3383         To fix these issues, I added two WebFrameLoaderClient callbacks;
3384         willReplaceMultipartContent() and didReplaceMultipartContent(). These
3385         are used to save and restore state between successive loads.

3587         REGRESSION (r183820): webkit.org/blog/ background painting issue on reload, when the page contains videos

3591
3592         After r183820, the media controls no longer had a wrapper that created CSS stacking context.
3593         The media controls on Mac use mix-blend-mode, which causes the compositing code to look for
3594         a stacking context ancestor and make it composited. After this change, it would walk up
3595         to a layer outside of the media element (e.g. the document element's layer), and make
3596         that composited. This triggered bugs with root background painting.
3597
3598         Prevent mix-blend-mode affecting content outside the media elements by having the media element's
3599         layer act as a stacking context.

3654
3655         Reviewed by Darin Adler.
3656
3657         WebVideoFullscreenInterfaceAVKit is used in both WebKit1 and WebKit2. In WebKit1, the model runs in the WebThread, while
3658         the interface is on the main thread. So there is code to dispatch between these two thread when communicating between the
3659         interface and the model. In WebKit2, this is handled automatically by the IPC mechanism. As a result, the threading code
3660         in WebVideoFullscreenbInterfaceAVKit and in WebVideoFullscreenModelVideoElement is redundant in WebKit2 and relies on
3661         WebThreadRun being a no-op in WebKit2.
3662
3663         This change clarifies this and simplifies the WebKit2 path by moving the WebKit1 specific threading code into
3664         WebVideoFullscreenControllerContext, which is the WebKit1 specific controller.

3912         When we fall off the end of the font fallback list, we ask the platform for which particular font we should use
3913         to display a particular codepoint. When we do this, we supply the font which is first in the fallback list so
3914         that the platform can try to match it as best it can. However, web fonts' FontPlatformData have a null m_font
3915         property, which means that we were passing nullptr to this platform fallback function.
3916
3917         The solution is something I've wanted to do for a while, which is migrate webfonts from using
3918         CGDataProviderCreateWithCFData() to using CTFontManagerCreateFontDescriptorFromData(). This call creates a
3919         CoreText font for an in-memory buffer (the old call was creating a CoreGraphics front from the same thing).
3920         This means that we can use the FontPlatformData constructor which accepts a CoreText font, thereby making web
3921         fonts not have a null m_font property. Note that not all platforms can use this call, which means that this
3922         new codepath is gated to only certain OSes (which is okay because only certain OSes use the
3923         CTFontCreatePhysicalFontDescriptorForCharactersWithLanguage() call inside FontCache). Because web fonts are the
3924         only user of the constructor which just takes a CG font, we can make the constructor private to the
3925         FontPlatformData class (as soon as all platforms can use this new codepath).

3938         An SVG with no intrinsic size does not draw correct slices when used as a border-image for an HTML element.

3940
3941         Reviewed by Darin Adler.
3942
3943         When using a non-intrinsic-sized image as an image-border, all the source
3944         slices have to be extracted from the top-left corner of the source image.
3945         This is because the right and bottom sides of the image can not be known.
3946         Also all the slices should not be stretched. In other words, the sizes of
3947         source slices for a non-intrinsic-sized image should be equal to the sizes
3948         of the destination container slices.
3949
3950         This is not compliant with the css3 w3c specs. I think the specs makes it
3951         harder to predict what exactly will be drawn for the image-border in this
3952         case. See http://www.w3.org/TR/css3-background/#border-image-slice. This
3953         approach is implemented by FireFox. And I think it gives a more predictable
3954         rendering for image-border in the case of non-intrinsic-sized images.
