   3         [GStreamer][WebRTC] Handle broken data in the libwebrtc GStreamer decoders

   7
   8         Listening to parsers warnings and error messages (synchronously so that we react
   9         right away) and requesting keyframes from the peer.
  10
  11         Also simplify the decoder code by trying to make decoding happen
  12         in one single pass, also hiding away GStreamer threading and allowing
  13         us to react as soon as the decoder/parser fails.

 146         [MSE][GStreamer] Don't use vorbisparse
 147         https://bugs.webkit.org/show_bug.cgi?id=200622
 148
 149         Reviewed by Philippe Normand.
 150
 151         This patch has been splitted from the original WebKitMediaSrc rework
 152         patch (https://bugs.webkit.org/show_bug.cgi?id=199719).
 153
 154         Unlike other parsers, vorbisparse has latency (in the sense that when
 155         it gets a chain call with a series of complete frames, it may not emit
 156         the parsed frames until another chain in the future), which makes it
 157         inappropriate for AppendPipeline, as there is no good way I know to
 158         flush it.
 159
 160         But actually vorbisparse is not known to be necessary and it was only
 161         introduced for consistency with other formats. Parsers are used in
 162         AppendPipeline to reconstruct information that is lost due to poor
 163         muxes. There have been no reported cases of this being a problem with
 164         Vorbis in WebM, so I'm just removing the parser.

 173         Factor complex line layout path out from RenderBlockFlow
 174         https://bugs.webkit.org/show_bug.cgi?id=200612
 175
 176         Reviewed by Zalan Bujtas.
 177
 178         This patch factors the line layout code that is currently part of the RenderBlockFlow and lives in RenderBlockLineLayout.cpp
 179         into a new ComplexLineLayout class. ComplexLineLayout is a member of RenderBlockFlow.
 180
 181         In the future we can stop constructing ComplexLineLayout at all when using other line layout paths.

 317         REGRESSION (r245974): Missing content on habitburger.com, amazon.com

 322
 323         In r245974 TileController::adjustTileCoverageRect() started to intersect the coverage
 324         rect with the bounds of the layer, which is wrong because this coverage rect is passed down
 325         to descendant layers, and they may project outside the bounds of this tiled layer.
 326
 327         This caused missing dropdowns on amazon.com, and a missing menu on habitburger.com on iPhone.
 328
 329         The fix is to just not do the intersection with the bounds. TileGrid::getTileIndexRangeForRect()
 330         already ensures that we never make tiles outside the bounds of a TileController.

 346
 347         The cause of the problem on iOS is that AccessibilityObject::firstAccessibleObjectFromNode
 348         used in AccessibilityRenderObject::linkedUIElements may return an object
 349         that is ignored by accessibility clients on iOS, and thus the client
 350         would not track the target of an internal link. This change ensures that
 351         accessibilityLinkedElement will return a valid accessibility element to
 352         the client, if it is exists.

 667         [WHLSL] Devirtualize the AST
 668         https://bugs.webkit.org/show_bug.cgi?id=200522
 669
 670         Reviewed by Robin Morisset.
 671
 672         This patch devirtualizes the AST for Type, Expression, and Statement.
 673         We now have an enum which represents all the concrete types in the
 674         three hierarchies. Doing dynamic dispatch is implemented as a switch
 675         on that type enum.
 676
 677         The interesting part of this patch is how to handle destruction. We do
 678         this by defining a custom deleter for all nodes in the AST. This ensures
 679         that when they're used inside UniqueRef, unique_ptr, Ref, and RefPtr,
 680         we do dynamic dispatch when we delete the object. This allows each base
 681         class to define a "destroy" method which does dynamic dispatch on type
 682         and calls the appropriate delete. We also mark all non-concrete nodes
 683         in all type hierarchies with a protected destructor, which ensures it's
 684         never called except from within the concrete child classes. We allow
 685         all concrete classes to have public destructors, as it's valid for
 686         their destructors to be called explicitly since there is no need for
 687         dynamic dispatch in such scenarios. All concrete classes are also marked
 688         as final.
 689
 690         This is a 3ms speedup on compute_boids, which is about a 10% improvement
 691         in the WHLSL compiler.

1144         [GL][GStreamer] activate wrapped shared context
1145         https://bugs.webkit.org/show_bug.cgi?id=196966
1146
1147         Reviewed by Žan Doberšek.
1148
1149         This patch consists in four parts:
1150
1151         1\ When the media player is instantiated, and it is intended to
1152         render textures, it will create a wrapped object of the
1153         application's GL context, and in order to populate the wrapped
1154         object with the GL vtable, the context has to be current. Thus,
1155         this patch makes current the shared WebKit application context,
1156         and populate the wrapped GstGLContext by activating it and filling
1157         in it. Afterwards, the wrapped context is deactivated.
1158
1159         2\ This patch makes GL texture use the RGBA color space, thus the
1160         color transformation is done in GStreamer, and no further color
1161         transformation is required in WebKit.
1162
1163         3\ Since it is not necessary to modify behavior if the decoder is
1164         imxvpudecoder, its identification and label were removed.
1165
1166         4\ As only RGBA is used, the old color conversions when rendering
1167         using Cairo (fallback) were changed to convert the RGBA, as in
1168         GStreamer's format, to ARGB32, as in Cairo format -which depends
1169         on endianness.
1170
1171         No new tests because there is no behavior change.
1172
1173         * platform/graphics/gstreamer/ImageGStreamerCairo.cpp:
1174         (WebCore::ImageGStreamer::ImageGStreamer): Only convert GStreamer
1175         RGBA to Cairo RGB32.
1176         * platform/graphics/gstreamer/MediaPlayerPrivateGStreamer.cpp:
1177         (WebCore::MediaPlayerPrivateGStreamer::createGSTPlayBin): Removes
1178         the IMX VPU identification.
1179         * platform/graphics/gstreamer/MediaPlayerPrivateGStreamerBase.cpp:
1180         (WebCore::MediaPlayerPrivateGStreamerBase::ensureGstGLContext):
1181         Intializes the wrapped GL Context.
1182         (WebCore::MediaPlayerPrivateGStreamerBase::updateTextureMapperFlags):
1183         Removes frame's color conversion.
1184         (WebCore::MediaPlayerPrivateGStreamerBase::createVideoSinkGL):
1185         Instead of parsing a string, the GstCaps are created manually, and
1186         it is set to appsink, rather than a filtered linking.
1187         * platform/graphics/gstreamer/MediaPlayerPrivateGStreamerBase.h:
1188         Removes ImxVPU enumeration value.
1189         * platform/graphics/gstreamer/VideoTextureCopierGStreamer.cpp:
1190         Adds NoConvert option to texture copier, setting an identity
1191         matrix.

1200
1201         Reviewed by Antti Koivisto and Wenson Hsieh.
1202
1203         The bug is caused by the content change observer detecting “Site Feedback” link at the bottom of
1204         the page (https://www.united.com/ual/en/US/account/enroll/default) constantly getting re-generated
1205         in every frame via requestAnimationFrame when the page is opened with iPhone UA string.
1206         Note that the content re-generation can be reproduced even in Chrome if iPhone UA string is used.
1207
1208         Ignore this constant content change in ContentChangeObserver as a site specific quirk.
1209
1210         In the future, we should make ContentChangeObserver observe the final location of each element
1211         being observed so that we can ignore content that like this which is placed outside the viewport,
1212         and/or far away from where the user tapped.

1227         The `PageAgent` is relied on by many of the other agents, so much so that it doesn't make

1229

1541         Instead of using a trie for unnamed type uniquing, use the same technique used
1542         in SynthesizeConstructors and use a HashMap of UnnamedTypeKeys. To make this
1543         profitable, we also need to devirtualize the hash and equality functions on
1544         UnnamedType, instead using an enum + switch. While this change only devirtualizes
1545         the UnnamedType subtree, we should probably do it for the entire AST in a future

1675
1676         Add to InteractionInformationAtPosition a ScrollingNodeID which represents the enclosing scrolling
1677         node that affects the targeted element's position. We use this to find a UIScrollView in the UI process.
1678
1679         The entrypoint to finding the enclosing scrolling node is ScrollingCoordinator::scrollableContainerNodeID(),
1680         which calls RenderLayerCompositor::asyncScrollableContainerNodeID() to look for a scrolling ancestor in
1681         the current frame, and then looks for an enclosing scrollable frame, or a scrolling ancestor in
1682         the enclosing frame.
1683
1684         There's a bit of subtlety in RenderLayerCompositor::asyncScrollableContainerNodeID() because if you're asking
1685         for the node that scrolls the renderer, if the renderer itself has a layer and is scrollable, you want

1868
1869         This started happening after r244494, which deferred editor state computation until the next layer tree flush
1870         when changing selection. After inserting a paragraph, the act of computing an editor state ensured that the text
1871         node containing the caret drops out of simple line layout, while grabbing the characters near the selection
1872         (i.e., calling charactersAroundPosition). This meant that when we subsequently ask positionAfterSplit whether it
1873         isRenderedCharacter() at the end of the command, we are guaranteed to have line boxes, so we get a meaningful
1874         answer and avoid inserting an extra non-breaking space.
1875
1876         However, after r244494, we defer the editor state computation until the end of the edit command; this means that
1877         we may not have line boxes for positionAfterSplit's text node renderer, due to remaining in simple line layout.
1878         In turn, this means that we end up hitting the assertion in containsRenderedCharacterOffset in debug builds; on
1879         release builds, we simply return false from containsRenderedCharacterOffset, which causes us to insert an extra
1880         space.
1881
1882         To fix this, we educate RenderText::containsRenderedCharacterOffset about simple line layout.

1895         I first contrasted the behavior of RenderTextLineBoxes::containsOffset in the cases where the OffsetType is
1896         CaretOffset or CharacterOffset, and found that the only interesting differences were:
1897
1898         1. The caret offset type case has special handling for line breaks.
1899         2. Both offset types have handling for reversed text.
1900         3. The end offset of a line box contains a caret offset, but not a character offset.
1901
1902         For the purposes of OffsetType CharacterOffset, (1) is irrelevant; furthermore, (2) is already not handled by
1903         logic in containsCaretOffset(). Thus, the only major difference in the CharacterOffset case should be (3), which
1904         we handle by only allowing the case where the given offset is equal to the very end of a text run for caret
1905         offsets, and not character offsets.

2003         [WHLSL] Make resolveFunction in Checker faster
2004         https://bugs.webkit.org/show_bug.cgi?id=200287
2005
2006         Reviewed by Robin Morisset.
2007
2008         This patch makes compute_boids faster by making function overload
2009         resolution faster inside the Checker. It's a ~6ms speedup in the
2010         checker. The main idea is to limit the number of overloads we need
2011         to look for by using a hash table that describes a function's type
2012         instead of just using a hash table keyed by a function's name.
2013
2014         The interesting implementation detail here is we must construct entries
2015         in the hash table such that they still allow constants to be resolved to
2016         various types. This means that the key in the hash table must normalize
2017         the vector of types it uses to express a function's identity. The normalization
2018         rules are:
2019         - int => float
2020         - uint => float
2021         - T* => float*
2022         - T[] => float*
2023
2024         The first two rules are because int constants can be matched against
2025         the float and uint types. The latter two rules are because the null
2026         literal can be matched against any pointer or any array reference
2027         (we pick float* arbitrarily). Even though it seems like these
2028         normalization rules would drastically broaden the efficacy of the hash
2029         table, we still see a 100x reduction in the number of overloads we must
2030         resolve inside compute_boids. We go from having to resolve 400,000
2031         overloads to just resolving 4,000.

2084         In the case where CFStringGetCStringPtr() succeeds in returning us a pointer
2085         to the CFStringRef underlying characters but it is not a common header, we
2086         would fall back to calling HTTPHeaderMap::set(const String&, const String&)
2087         which would unecessarily call findHTTPHeaderName() again to try and determine
2088         if it is a common header. Avoid this by introducing a new setUncommonHeader()
2089         private method and calling this one instead. Also got rid of some code
2090         duplication at the same time.

2103         [WHLSL] Remove the auto initialize variables pass
2104         https://bugs.webkit.org/show_bug.cgi?id=200472
2105
2106         Reviewed by Robin Morisset.
2107
2108         From a separation of concerns perspective, it's a bit nicer to make variables
2109         without initializers call their default constructors as a transformation over the AST.
2110         This removes the need for the lowering to need to worry about such things. However,
2111         changing metal lowering to deal with this is trivial. It means we need to change one
2112         line of code in Metal code generation, and we get to remove a ~50 LOC AST pass.
2113         Also, in this case, it saves us from the compile time hit of having to run the
2114         auto initialize variables phase, which takes ~1.2ms on compute_boids.

2132         Avoid string copies by passing a single StringBuilder all the way through Metal code

2259         [WHLSL] Reduce the number of variables that make it into the global struct by skipping stdlib functions and internal uses of MakePointerExpression/MakeArrayReference
2260         https://bugs.webkit.org/show_bug.cgi?id=200463
2261
2262         Reviewed by Myles C. Maxfield.
2263
2264         This patch makes it so that we put fewer variables in the global struct.
2265         This decreases end-to-end running time in compute_boids by 30% (with p = 0.0001).
2266
2267         We achieve this in two ways:
2268         1. We track if each function is user code or "standard library" code. We also
2269         count native functions as the standard library. We know a priori that the
2270         standard library never escapes any variables. So the preserve variable
2271         lifetimes phase skips analyzing all standard library functions and also
2272         skips passing the global struct to any standard library functions.
2273
2274         2. We internally emit MakePointerExpression/MakeArrayReferenceExpression nodes in
2275         the compiler in various phases. We sometimes emit these nodes in such a way
2276         that we know that this address-of expression does not cause the variable to
2277         escape. We now mark each address-of expressions as either:
2278         - Conservatively escaping. We conservatively do this for all user code.
2279         - Not escaping. This means that this address-of operation definitely does
2280         not escape the variable. If a variable never has an escaping use, we will
2281         omit putting this variable in the struct.

2412         Makes a couple of minor adjustments to how layout size scale factor is handled in ViewportConfiguration, to
2413         address some scenarios in which adjusting WKWebView's _viewScale does not have any apparent effect on the page.
2414         See changes below for more detail.

2418
2419         * page/ViewportConfiguration.cpp:
2420         (WebCore::ViewportConfiguration::initialScaleFromSize const):
2421
2422         When the page is either zoomed in or zoomed out using _viewScale, let the specified initial scale take
2423         precedence over the scale computed by fitting the content width to the view width, or the scale computed by
2424         fitting the content height to the view height.
2425
2426         This avoids a scenario in which nothing happens when increasing view scale in a responsively designed web page
2427         that has a fixed minimum width. Before this change, when computing the initial scale at a view scale that would
2428         not allow the entire content width of the page to fit within the viewport, the new initial scale would remain
2429         unchanged if the initial scale in the meta viewport is not also set to 1, because a new initial scale would be
2430         computed in ViewportConfiguration::initialScaleFromSize to accomodate for the entire content width.
2431
2432         Our new behavior allows us to zoom into the page, even if doing so would cause horizontal scrolling.
2433
2434         (WebCore::ViewportConfiguration::updateConfiguration):
2435
2436         When the page is either zoomed in or zoomed out using _viewScale and the default viewport configuration has a
2437         fixed width (e.g. on iPhone), then adjust the width of the default viewport configuration to account for the
2438         _viewScale. For example, the default width of a viewport-less web page is 980px on iPhone; at a view scale of 2,
2439         this would become 490px instead, and at 0.5 view scale, it would become 1960px.
2440
2441         This ensures that on iPhone, for web pages without a meta viewport, changing the view scale still changes the
2442         layout and initial scale of the web page.

2944         Mangled WHLSL names don't need to allocate Strings

2946
2947         Reviewed by Saam Barati.
2948
2949         To avoid allocating strings for each mangled name used to transform WHLSL to Metal, which we'd
2950         like to avoid since it is both unnecessarily expensive in time and space, we can instead just
2951         store the unique integer identifier that was being used to construct the String.
2952
2953         Since the existing mangled names were all of the form "prefix" + unsigned integer value (where
2954         prefix could be "type", "enumerationMember", "structureElement", "variable" or "function") we
2955         strongly type the integer by storing it in a struct (MangledVariableName, MangledTypeName, etc.)
2956         When the full name is actually needed, StringTypeAdapter's specialized for the structs are
2957         used to write directly into the preallocated buffers of StringBuilders or makeString().

2967
2968         Additionally, a Variant, MangledOrNativeTypeName, of MangledTypeName and String is
2969         declared to allow for the few cases where a native type (e.g. float4) is needed. The
2970         StringTypeAdapter for MangledOrNativeTypeName could be generalized for any Variant
2971         in the future, but I left it non-general for now, as it is non-obvious if one would
2972         want to store Variant<Types...>, and have each member function construct a temporary
2973         StringTypeAdapter, or store a Variant<StringTypeAdapter<Types>...> and perform conversion
2974         in the construction.

3095
3096         Reviewed by Antti Koivisto.
3097
3098         The intrinsic width for a formatting root box has 2 sets of values now. One set(min/max) is stored in the established formatting context's state
3099         while the other is in the formatting context's state where the box lives.
3100
3101         <div style="position: absolute"><div style="float: left; border: 1px solid green">foobar</div></div>
3102
3103         The float box participates in the formatting context established by the absolutely position box, but it also establishes an inline formatting context.
3104         The min/max width pair in the established context is the width of the "foobar" (same value for min/max). This set is stored in the inline formatting state.
3105         However the float box has horizontal border so the "final" min/max width pair is expanded by this border value and stored in the formatting state where
3106         the box lives (which is different from the one it establishes).
3107
3108         This and the "remove the formatting context type classes from the tree" changes open up interesting optimization opportunities.
3109         Here is a very simple case:
3110         <div style="display: inline-block; width: auto;">
3111           <div style="float: left">some text</div>
3112           <div style="float: left">some super long .... text</div>
3113           <div></div>
3114         </div>
3115         In order to lay out this content properly, we
3116         1. Compute the min/max width of the first float (expensive text measuring)
3117         2. Compute the min/max width of the second float (some more expensive text measuring)
3118         3. Compute the min/max width of the inline-block (that is pretty much the 2 float's min/max)
3119         4. Lay out the 2 floats, the empty div and the inline-block using these min/max width pairs.
3120
3121         Now if the inline-block box's display value is changed to "block" and the positioning is to absolute (style="display: box; position: absolute;")
3122         we currently(on trunk) tear down the render tree, build a new one and run all the steps again from #1 to #4.
3123
3124         In LFC, we start with the following layout tree
3125         <container> -> block formatting context
3126           <container> -> inline formatting context
3127             <anonymous inline box>
3128           <container> -> inline formatting context
3129             <anonymous inline box>
3130           <container> -> inline formatting context
3131         and when the style change happens, we don't need to tear down the tree at all. Not only that, but since every formatting contexts stay the same
3132         we can just reuse their states and actually skip all the steps (even the positioning since the absolutely positioned container has static top/bottom/left/right).
3133
3134         Surprisingly the final layout produces the exact same "display boxes" as the original layout.

3169         Web Inspector: DOM: add a special breakpoint for "All Events"
3170         https://bugs.webkit.org/show_bug.cgi?id=200285
3171
3172         Reviewed by Joseph Pecoraro.
3173
3174         Similar to the existing "All Requests" breakpoint, there should be a way to set a breakpoint
3175         that would pause for any DOM event, regardless of the event's name. This is useful for
3176         situations where the event name isn't known, or where one simply want's to pause on the next
3177         entry to the event loop.
3178
3179         Along these lines, make the "requestAnimationFrame", "setTimeout", and "setInterval"
3180         event breakpoints into special breakpoints that can be added/removed via the create
3181         breakpoint context menu. This simplifies the process for setting these breakpoints, and also
3182         makes them more discoverable (most people wouldn't consider them to be "events").

3202         the corresponding breakpoint that is added/removed is treated as a global breakpoint that
3203         applies to all events of that type (e.g. a global `listener` breakpoint would pause for any

3620
3621         DOMWindow properties may get GC'd before their Window object once their frame is detached. This
3622         is unexpected behavior given that these properties persist on the Window after the frame is
3623         detached. This patch thus updates their bindings so that they live as long as their window, not
3624         their frame.
3625
3626         Note that this also fixes a thread-safety issue since DOMWindowProperty::frame() would get called
3627         from GC threads, although its implementation looks like:
3628         """
3629           return m_window ? m_window->frame() : nullptr;
3630         """
3631
3632         Because m_window is a WeakPtr<DOMWindow> and because windows get destroyed on the main thread,
3633         we could in theory crash when dereferencing m_window->frame() from the GC thread.

3744
3745         When doing metal code generation, we frequently know whether something
3746         is null or not. This patch does a basic propagation of this information
3747         to avoid emitting excessive null checks in the generated Metal code.
3748         This is a 6% speedup (with a p value of 0.0001) in Metal compile times
3749         on compute_boids.
3750
3751         An example of a null check we now eliminate is:
3752         ```
3753         int x;
3754         thread int* ptr = &x; // We know that the lvalue for "x" is non-null, so we produce a non-null rvalue here.
3755         *ptr = 42; // We know that the "ptr" rvalue is non-null, so we omit the null check.

3771
3772         Reviewed by Darin Adler.
3773
3774         To enable directory uploading in WebKit2, we extended WebKit1's model of asking the application to generate a file for uploading.
3775         This means the WebProcess needed access to everything necessary to zip a whole directory, and clients that have not implemented
3776         the strange WKBundlePageUIClient callbacks won't be able to upload directories.  Safari's implementation had already been copied
3777         to BlobDataFileReference::generateReplacementFile, so I reused that code to do the zipping.  Instead of a complicated model of
3778         keeping track of a filename, possibly a generated filename, and whether we think we own the file or not and having nobody clean up,
3779         we now do the generation, use, and cleaning up in the network process starting with a new function generateFilesForUpload.
3780         This removes unimplemented SPI in WebUIDelegatePrivate in WebKitLegacy and stops calling the WKBundlePageUIClient related to upload
3781         file generation and replaces them with automatic behavior equivalent to Safari's implementation of the WKBundlePageUIClient calls.
3782         Since we no longer need to do these file operations in the WebProcess, I am also reverting r245322 and r246077 which tightens the sandbox.

3841
3842         Makes some targeted adjustments to the text autosizing heuristic, to ensure compatibility with several high-
3843         profile websites. See changes below for more detail.

3848         * css/StyleResolver.cpp:
3849         (WebCore::StyleResolver::adjustRenderStyleForTextAutosizing):
3850
3851         Avoid clipped sidebar links on sohu.com by not performing line-height boosting in the case where the element
3852         probably has a small, fixed number of lines. See below for more detail. Additionally, don't attempt to adjust
3853         the line height using the boosted font size, in the case where the element is not a candidate for idempotent
3854         text autosizing.
3855
3856         * rendering/style/RenderStyle.cpp:
3857         (WebCore::RenderStyle::isIdempotentTextAutosizingCandidate const):
3858
3859         Make various targeted hacks to fix a few websites:
3860
3861         -   Add a special case for top navigation bar links on yandex.ru, where line height greatly exceeds the
3862             specified font size.
3863
3864         -   Avoid boosting some related video links on v.youku.com by considering the line-clamp CSS property when
3865             determining the maximum number of lines of text an element is expected to contain.
3866
3867         -   Avoid boosting some front page links on asahi.com, which have non-repeating background images.
3868
3869         -   Add several other adjustments to more aggressively boost pieces of text on Google search results, such as
3870             taking the `word-break` CSS property into account.
3871
3872         The bottom few pixels of sidebar links on naver.com are also no longer clipped after these changes.
3873
3874         * rendering/style/TextSizeAdjustment.cpp:
3875         (WebCore::AutosizeStatus::probablyContainsASmallFixedNumberOfLines):
3876
3877         Pulls out a piece of the heuristic added to fix sephora.com in r247467 out into a separate helper method. To
3878         recap, this heuristic identifies elements with both a fixed height and fixed line height, for which the fixed
3879         height is close to an integer multiple of the line height.
3880
3881         Also makes several small tweaks in the process: (1) change the max difference between fixed line height and
3882         font size from 6 to 5 to ensure that some multiline caption text on Google search results is boosted, and (2)
3883         replace usages of `lineHeight()` with `specifiedLineHeight()`, which current prevents this function from being
3884         truly idempotent.
