  32         [DOMJIT] Add a way for DOMJIT::Patchpoint to express effects

  36
  37         CallDOMPatchpoint now has the way to tell its effects to DFG and FTL compilers.
  38         WebCore DOMJIT::AbstractHeapRepository will construct the hierarchy of the abstract
  39         heap. And then it encodes these information into the pairs of the integers.
  40
  41         And this patch also changes the DOMJIT::PatchpointParams' parameter order.
  42         So we change them in all the DOMJIT::CallDOMPatchpoint sites.

 181         [CodeGenerator] Only allow a single interface or standalone dictionary per WebIDL file
 182         https://bugs.webkit.org/show_bug.cgi?id=163889
 183
 184         Reviewed by Chris Dumez.
 185
 186         Assert that there's only one interface or standalone dictionary
 187         per WebIDL input file, and exit from the generator otherwise.
 188
 189         This avoids potential linking issues where multiple enumeration
 190         and dictionary bindings code can be generated if the source
 191         WebIDL for them is specified in a file that contains multiple
 192         interfaces or standalone dictionaries.
 193
 194         Additionally, the generator now also exits if it fails to
 195         generate code for any interface of standalone dictionary. This
 196         should avoid processing WebIDL files that are empty in
 197         substance.
 198
 199         TestException.idl and TestInterface.idl files have their second
 200         interfaces removed. In place of those a new testing IDL file is
 201         added, TestInterfaceLeadingUnderscore.idl. Like the two removed
 202         interfaces, it tests that the leading underscode in the
 203         identifier is removed by the generator.

 359         [CodeGeneratorJS] Support enums for standalone dictionaries
 360         https://bugs.webkit.org/show_bug.cgi?id=163885
 361
 362         Reviewed by Youenn Fablet.
 363
 364         Add support for enumerations in WebIDL files that specify
 365         standalone dictionaries. Implementation of this is pretty
 366         straight-forward and mirrors interface and callback generators
 367         by calling GenerateEnumerations{Header,Implementation}Content()
 368         functions in GenerateDictionary{Header,Implementation}().
 369
 370         In GenerateEnumerationsImplementationContent(), the
 371         NeverDestroyed.h header is added to the implementation includes
 372         since that class is used to hold an array of possible enum
 373         values.
 374
 375         A test enum is added to the TestStandaloneDictionary.idl file
 376         and the baselines are updated to reflect the new capability.

 401         Remove CSSCharsetRule from the CSS OM. All other browser engines have made this
 402         change. This eliminates the weird overloading of isCharsetRule to match both
 403         CSSCharsetRule and StyleRuleCharset (only used by the new parser).
 404
 405         Fix the destroy() method in StyleRuleBase to clean up StyleRuleCharsets created
 406         by the new parser properly.

 428         [CodeGeneratorJS] Standalone dictionaries have misplaced build guards
 429         https://bugs.webkit.org/show_bug.cgi?id=163881
 430
 431         Reviewed by Chris Dumez.
 432
 433         Build guards that are generated from the Conditional attribute
 434         on WebIDL dictionary declarations properly guard the relevant
 435         convertDictionary() functions for WebIDL files that also specify
 436         interfaces. But for standalone dictionaries these build guards
 437         should guard the complete header and implementation files, much
 438         like this is done for files that originate from interfaces or
 439         callbacks.
 440
 441         Before this patch, guarding a standalone dictionary resulted in
 442         malformed output because GenerateHeaderContentHeader() and
 443         GenerateImplementationContentHeader() functions both generated
 444         the #if macro that would guard the whole file, but
 445         GenerateDictionary{Header,Implementation}() didn't generate the
 446         closing #endif.
 447
 448         CodeGeneratorJS.pm now passes the conditional string, if any,
 449         to GenerateDictionary{Header,Implementation}Content() functions
 450         in case of a non-standalone dictionary. Otherwise, the
 451         conditional string, if any, is used to guard the complete
 452         header and implementation files.
 453
 454         Generator tests are updated to cover various build guard
 455         combinations on dictionaries in TestObj.idl, and the standalone
 456         dictionary WebIDL file now has a Conditional attribute to check
 457         that the build guards cover complete generated header and
 458         implementation files.

 889         [WebIDL] Add IDLType based toJS conversion

 891
 892         Reviewed by Darin Adler.
 893
 894         Adds toJS<IDLType>() functions to be the new way of converting
 895         from implementation types to JS types. These are implemented via
 896         a similar mechanism to the convert<IDL>() functions, though specializations
 897         of a JSConverter struct (rather than the Converter structs). This allows
 898         us to support arbitrarily complex aggregate types easily (e.g. sequence<(Node or DOMString?)>).
 899
 900         * Modules/geolocation/Geoposition.idl:
 901         * dom/Event.idl:
 902         Add typedef for DOMTimeStamp. Eventually, our IDLParser should do this for us, but
 903         for now it allows us to simplify the type system.

 922
 923         * bindings/js/JSDOMConvert.h:
 924         (WebCore::toJS):
 925         Add 5 primary toJS functions which take combinations of the following
 926         arguments: ExecState, JSDOMGlobalObject, ThrowScope.  All take the value
 927         to be converted as well, except in the case of the throwScope ones, where
 928         they take the value in an ExceptionOr<>.
 929
 930         To simplify the implementations of the JSConverter specializations, avoiding
 931         the need for each one to implement their conversion up to 3 times (one for just
 932         the value, one for the value and the ExecState, and one for the value, the ExecState
 933         and the global object), each JSConverter instead specifies whether it's converter
 934         needs an ExecState or global object via a static constexpr. We then use the
 935         JSConverterOverloader template, to call the correct function. This can probably be
 936         improved in the future, by inferring the number of arguments needed via SFINAE, but
 937         this seemed like a more straightforward first cut.

1184         Fix repainting of slow repaint objects in WK1 when page scale is applied
1185         https://bugs.webkit.org/show_bug.cgi?id=163854
1186
1187         Reviewed by Zalan Bujtas.
1188
1189         RenderObject::repaintSlowRepaintObject() always set the repaint container to the RenderView
1190         if it was null. This is before the call to clippedOverflowRectForRepaint(). If that function
1191         is called with a null repaintContainer, it maps the rect up through the RenderView's transform
1192         (which represents page scale), which is what we want here. Passing the RenderView itself
1193         stops the transform from being applied, which led to the bug.
1194
1195         WebKit2 doesn't suffer from this bug because containerForRepaint() always returns the
1196         composited RenderView.

1869
1870         * platform/graphics/IntSize.h:
1871         (WebCore::IntSize::area): Change to return a
1872         Checked<unsigned, T> value. Use WTF:: namespace to avoid
1873         including another header.

1876         (WebCore::IntRect::area): Ditto.
1877

1960         Reviewed by Alex Christensen.
1961
1962         Overload resolution was wrong if one of the types was a nullable union. This
1963         is because we never considered the union type itself, only its subtypes.
1964         Therefore, we checked if any of the union's subtypes were nullable but we
1965         failed to check if the union itself was nullable.

2046         Reviewed by Anders Carlsson.
2047
2048         When we receive mouse/keyboard events in a page, we want to prevent AppNap. We currently do so
2049         via the PageThrottler. This patch is to just make the WebPage drive the UserActivity directly.
2050
2051         Two reasons to do so: (1) to cleanup & simplify for further refactoring. (2) The current code
2052         isn't really achieving the desired effect. The page setting the flag in the throttler to get
2053         the activity to be set is now a less effective way of achieving this goal, since the
2054         PageActivityState bounces back across to the UI process & then messages back to the WebContent
2055         process to take the UserActivity. These extra hops defeat the purpose of making sure the boost
2056         from the initial message isn't lost.

2075         events are fired in the correct order with respect to each other, additional work will be required to ensure
2076         that input events are fired in the correct order with respect to composition(start|update|end) events and
2077         textInput events. This is held off until the expected ordering of events is officially defined in the spec.

2151
2152         Reviewed by Eric Carlson.
2153
2154         When seeking a MediaPlayerPrivateMediaSourceAVFObjC, we will first seek the AVSampleBufferRenderSynchronizer,
2155         flush and enqueue non-displaying frames, enqueue regular frames, then begin playback. The above stall will occur
2156         when we enqueue so many non- displaying frames that the display layer is not ready for normal ones before
2157         playback begins. Then, when the synchronizer attempts to synchronize the enqueued audio and video renderers, the
2158         only available samples are back at the original media time, and so it "seeks" by updating the CMTimebase back to
2159         the original media time, causing playback to appear "stalled".  The overall solution is to "flush" the contents
2160         of the renderers before the seek, so that the synchronizer doesn't reset the currentTime, and to only restart
2161         the synchronizer when there are visible (or audible) samples available for display.
2162
2163         Breaking the fix down into sections:
2164
2165         = Don't enqueue too many non-displaying samples at once:
2166         - Rename SourceBufferPrivate::flushAndEnqueueNonDisplayingSamples() to SourceBufferPrivate::flush(), and no longer
2167           pass in an array of non-displaying samples.
2168         - Add a new virtual method to MediaSample, createNonDisplayingCopy(), used by SourceBuffer to enqueue non-displaying
2169           samples.
2170         - in SourceBuffer::reenqueueMediaForTime(), use that new createNonDisplayingCopy() method to enqueue non-displaying
2171           samples in the same queue as regular samples.

2271         The parameter is nullable for both overloads which is not valid IDL.
2272
2273         - sortedTrackListForMenu(): The parameter is no longer nullable. This is a minor
2274           behavior change and it should be safe since this is Apple-specific and only
2275           called from mediaControlsApple.js which uses HTMLMediaElement.videoTracks and

2277           Note that we could have also kept one of the parameters as nullable to not
2278           change behavior but allowing null does not seem useful here.

2316         Because m_sessions can be mutated by removeSession() while iterating over m_sessions, and because
2317         PlatformMediaSessions are not refcounted, it is not enough to copy m_sessions into a copied Vector
2318         before iterating. Instead, wrap iteration of m_sessions in a convenience function, which sets an
2319         iteration counter which, when cleared, removes all null entries from m_session. In parallel, modify
2320         removeSession() to check this iteration counter, and replace the session with a null value rather

3123         When SourceBuffer receives a sample in sourceBufferPrivateDidReceiveSample() containing
3124         a trackID not previously seen in an initialization segment, it creates a default TrackBuffer
3125         object to contain that track's samples. One of the fields in TrackBuffer, description, is
3126         normally filled out when an initialization segment is received, but with this default
3127         TrackBuffer, it's still null when it's checked later in sourceBufferPrivateDidReceiveSample().
3128
3129         Rather than adding a null-check on trackBuffer.description, drop any sample that has a
3130         trackID which was not present during a previous initialization segment.

3328         Because of platform lack of support for variations in in-memory fonts,
3329         this feature should be disabled on the affected OSes.
3330
3331         No tests because there is no behavior change (on the relevant platforms).
