…y CreateTemporalX helpers https://bugs.webkit.org/show_bug.cgi?id=321041 rdar://184072358 Reviewed by Yusuke Suzuki. Every CreateTemporalX AO validates its slots before OrdinaryCreateFromConstructor, whose Get(NewTarget, "prototype") is observable. All eight Temporal constructors derived their Structure on entry, so Reflect.construct with a throwing `prototype` accessor got that error instead of the mandated RangeError. The helpers now take a TemporalNewTarget rather than a Structure*, making the wrong order unrepresentable, and are renamed after their AOs as free functions — createTemporalDate, createTemporalZonedDateTime and so on. `try*` in WebKit means "returns null without throwing", the opposite of these. Two bugs found on the way: ZonedDateTime.prototype.with open-coded InterpretISODateTimeOffset without its CheckISODaysRange and IsValidEpochNanoseconds steps, so an offset at the epoch boundary produced an out-of-range ZonedDateTime; and isValidPlainDateOrThrow threw through its own ThrowScope, leaving the caller's unchecked under --validateExceptionChecks. Also folds CalendarID into CreateTemporalYearMonth/MonthDay, adds the missing CreateTemporalInstant, and corrects the step annotations in all eight.

… background is obscured https://bugs.webkit.org/show_bug.cgi?id=320829 rdar://183841775 Reviewed by Antti Koivisto. This patch aligns WebKit with Gecko / Firefox and Blink / Chromium. Merge: https://chromium.googlesource.com/chromium/src.git/+/f3d25d319c4feb8ad68c6fde2b3ef3972384f1fe RenderBox::foregroundIsKnownToBeOpaqueInRect() computes whether a box's background is obscured by recursively checking if any descendant fully covers it, letting BackgroundPainter skip painting the background. The recursion did not account for descendants with CSS clip, so an ancestor could be treated as obscured even though the covering descendant only painted part of its border box. RenderBox::backgroundIsKnownToBeOpaqueInRect() already bails out on hasClip(), so a directly clipped child was handled. The gap was one level down: a clipped child with no background of its own was still recursed into, and an opaque grandchild filling that child was taken as covering the ancestor. The clip on the intermediate child was never consulted. Reject clipped boxes in isCandidateForOpaquenessTest() instead of in backgroundIsKnownToBeOpaqueInRect(), since CSS clip applies to a box's foreground as well as its background. hasClip() is isOutOfFlowPositioned() && !style().clip().isAuto(), so it already encodes that clip only applies to out-of-flow boxes. This makes the obscuration optimization fire less often and so paints some backgrounds that were previously skipped. The compositing path is unaffected: RenderLayerBacking::setContentsOpaque() reaches RenderBox::backgroundIsKnownToBeOpaqueInRect(), which already checked hasClip().

https://bugs.webkit.org/show_bug.cgi?id=321027 rdar://184062042 Reviewed by Mike Wyrzykowski. The IPC code generator emits a C++ message forwarder for receivers marked SwiftReceiver or SwiftReceiverBuildEnabledBy, and that forwarder, rather than the receiver itself, becomes the IPC::MessageReceiver. When such a receiver is also annotated with EnabledBy, the generated enablement check calls sharedPreferencesForWebProcess() unqualified. That method is declared by individual receivers rather than by the IPC machinery, and is absent from both IPC base classes, so it is not visible on the forwarder and the generated code fails to compile. Both shipping Swift receivers use ExceptionForEnabledBy, which is why this has gone unnoticed. It blocks moving stream receivers such as RemoteMesh, annotated EnabledBy=ModelElementEnabled, to Swift. Have the forwarder ask its target for the preferences, and look the target up before the enablement check so that it is available. The receiver-level gate and the per-message gates read the same local, so this repairs both. The two statement generators are merged into one function so that the ordering is structural rather than a convention repeated at each of the three call sites. Generated output for non-Swift receivers is unchanged. A Swift receiver annotated with EnabledBy must now expose sharedPreferencesForWebProcess() to C++. Since Swift cannot name an un-specialized class template, std::optional<SharedPreferencesForWebProcess> will need a named typedef, in the same way std::span<const char> already does for WebBackForwardList. Covered by two new fixtures in the IPC message-generator test, TestWithStreamSwiftEnabledBy (Stream with a receiver-level EnabledBy) and TestWithSwiftConditionallyAndEnabledBy (SwiftReceiverBuildEnabledBy with per-message EnabledBy). * Source/WebKit/Scripts/webkit/messages.py: (generate_target_and_enabled_by_statements): (generate_target_and_enabled_by_statements.append_swift_statements): (generate_target_and_enabled_by_statements.append_cpp_statements): (generate_message_handler): (generate_enabled_by_for_receiver): Deleted.

… its margin when the root has a border https://bugs.webkit.org/show_bug.cgi?id=321087 Reviewed by Antti Koivisto. LineBuilder::initialize() skips a pending margin when the margin state is still at the before side of the block, on the grounds that it can collapse out through that edge. That is only half the condition. RenderBlockFlow::MarginInfo says: bool canCollapseWithMarginBefore() const { return m_atBeforeSideOfBlock && m_canCollapseMarginBeforeWithChildren; } When the root has a border or padding the margin cannot collapse through its before edge, so a self collapsing block on a previous line has already committed it and the line has to move down by it. Skipping it dropped the margin outright: the block painted below while the content following it stayed at the container's top. * Source/WebCore/layout/formattingContexts/inline/InlineLineBuilder.cpp: (WebCore::Layout::LineBuilder::initialize): * LayoutTests/imported/w3c/web-platform-tests/css/CSS2/normal-flow/block-in-inline-self-collapsing-margin-001-expected.txt: Added. * LayoutTests/imported/w3c/web-platform-tests/css/CSS2/normal-flow/block-in-inline-self-collapsing-margin-001.html: Added.

…CG switch https://bugs.webkit.org/show_bug.cgi?id=321021 rdar://182280016 Reviewed by Ryosuke Niwa. When Site Isolation is off, we sometimes don't consider the WebProcess that hosts the webpage as a candidate for running same-origin shared and service workers. This is unintended. This occurs because we only record the process => site association at provisional load time, not commit time. In the case of a forced process swap due to a COOP response header: 1. Process A performs the provisional load, and records the process => site mapping. 2. We handle the COOP response header and force a BCG and process switch. 3. Process B continues the load and commits, but we never record a process => site mapping for this new process. To fix this, record the process => site mapping at commit time. This only needs to occur when Site Isolation is off; when Site Isolation is on, we were already recording the process => site mapping via a different path (in didStartUsingProcessForSiteIsolation).

…eInfo` https://bugs.webkit.org/show_bug.cgi?id=321096 rdar://184135720 Reviewed by Richard Robinson. Add a way for text extractions to grab a `WKFrameInfo`, corresponding to a node `uid` string. If the `uid` corresponds to an `iframe`, this finds the frame info corresponding to the content frame of the `iframe` element; otherwise, it falls back to returning the content frame containing the given target node. This allows agents to (for instance) evaluate script in the context of the content frame underneath an `iframe`, without requiring the agent to first extract content within the target subframe.

https://bugs.webkit.org/show_bug.cgi?id=321093 Reviewed by Antti Koivisto. The CSSWG resolved that margin-trim applies to block and multi-column containers only (w3c/csswg-drafts#13731), reverting the 2019 resolution that had extended it to flex and grid. That one predates gaps, and row-gap/column-gap covers the spacing its author was asking for. RenderFlexibleBox::isChildEligibleForMarginTrim is what made the shared RenderBox/RenderBlock trimming paths fire for flex items, so dropping the override turns them all off at once. This also removes the main- and cross-axis trim passes in FlexFormattingContext, FlexLayoutState's margin-trim item sets, and what they leave unreferenced. The two stray comments above the deleted override, about hasIntrinsicAspectRatio and template instantiations, described neither it nor its neighbor and go with it. Grid and block keep margin-trim, so all four values still parse. Removing grid, and with it the inline-* values that then have no applicable layout mode, is a follow-up, as is dropping these tests from WPT upstream. *

LineLayout::firstLineBaseline() returns a block-in-inline's own baseline, but callers expect a baseline measured from the container's border box. RenderBlock's equivalents add the child's logicalTop() for exactly this reason: if (auto baseline = child->firstLineBaseline()) return LayoutUnit { (child->logicalTop() + baseline.value()).toInt() }; So anything above the block level box - the container's padding-before, or a preceding line - is dropped from the exported baseline. * Source/WebCore/layout/integration/inline/LayoutIntegrationLineLayout.cpp: (WebCore::LayoutIntegration::LineLayout::firstLineBaseline const): * LayoutTests/imported/w3c/web-platform-tests/css/css-align/baseline-rules/first-baseline-block-in-inline-001.html: Added. * LayoutTests/imported/w3c/web-platform-tests/css/css-align/baseline-rules/first-baseline-block-in-inline-001-expected.txt: Added.

…eaded animations after a progress-based timeline changes source <https://bugs.webkit.org/show_bug.cgi?id=320837> <rdar://183856184> Reviewed by Antoine Quint. Every entry in `processTimelines` is expected to hold at least one timeline, since an entry with an empty set describes a scrolling node that no longer sources anything. Taking a timeline out of its former source and moving it to a new one empties that set, so the invariant must be restored on every update. Restoring it only while iterating `timelinesUpdate.destroyed` fails to remove empty source entries from `processTimelines` whenever an update does not destroy a timeline, so they survive until some later update for that process destroys one. Sweep empty entries unconditionally so the invariant no longer depends on what an update happens to contain. Erasing them in a single pass also removes the need to collect their keys in a temporary `HashSet`. No new tests since an empty entry is indistinguishable from an absent one through the existing testing interfaces. * Source/WebKit/UIProcess/RemoteLayerTree/RemoteProgressBasedTimelineRegistry.cpp: (WebKit::RemoteProgressBasedTimelineRegistry::update): Canonical link: https://commits.webkit.org/318657@main
…equests rdar://184133528 https://bugs.webkit.org/show_bug.cgi?id=321112 Reviewed by Ryan Reno. In 315856@main we added what was meant to be restrictions on which properties an application could override in an NSURLRequest they pass in to the WebKit API. That patch included logging of "violations" to help diagnose breakage that might later occur. The restrictions and logging were implemented in the CoreIPCNSURLRequest IPC wrapper, with the intention of catching app-supplied properties in the UIProcess before being sending to other processes. But this had the side effect of catching NSURLRequests created from within WebKit itself, such as the requests that come from CoreMedia for <audio>/<video> playback. There is a specific set of properties that ResourceRequest handles directly that we explicitly serialize out of the property set, but also passed into the "app provided property" santizing path.

A partial layout that resumes at a later line never re-runs the block, so the rest of the content runs with an empty margin state and the margin is simply dropped. partialContentTop compounds it: it is derived from the previous line's lineBoxLogicalRect().maxY(), which excludes the margin. Bail to a full layout when any line before the damaged one holds a block level box.

It returned the host's renderer unconditionally, but a host with `display: contents` has no renderer. Its user agent shadow content can still establish a scrollable area, so all three callers dereferenced null. A <details> is exactly that case: its ::details-content is a slot in the user agent shadow root, so giving the <details> `display: contents` and the ::details-content non-visible overflow crashed the WebContent process while resolving the scroll corner style during render tree construction. This is the standard way to build an animated disclosure widget whose summary participates in a parent grid, so it is reachable from ordinary content. Null check the host's renderer and fall back to the renderer establishing the scrollable area, which is the pre-existing behavior for content outside a user agent shadow root. Only the null case changes behavior. * Source/WebCore/rendering/RenderLayerScrollableArea.cpp: (WebCore::rendererForScrollbar): The host is not guaranteed to have a renderer.

…r-move of lvalue arguments <https://bugs.webkit.org/show_bug.cgi?id=321098> <rdar://184137472> Reviewed by Mike Wyrzykowski. The `T&&` parameter of `allocateAbstractType()` is a forwarding reference, so a non-const lvalue binds to it in preference to the `const T&` overload, and the unconditional move then moves the lvalue. The generated overloads in `TypeOverloads.h` pass the same `TypeVariable` lvalue to `allocateAbstractType()` more than once per candidate (e.g. `(T, T) => T`), so the Clang static analyzer reports a use-after-move. This never crashed only because `TypeVariable` is trivially copyable, so the move is really a copy; it would be a genuine use-after-free if a non-trivial member were ever added. Forward the argument instead so an lvalue is copied and only an rvalue is moved. Because the generated candidates always pass an lvalue, no move happens, so the fix stays correct regardless of whether `TypeVariable` remains trivially copyable. A single forwarding overload handles every value category, making the separate `const T&` overload redundant. No new tests since no change in behavior. * Source/WebGPU/WGSL/Overload.h: (WGSL::allocateAbstractType): Canonical link: https://commits.webkit.org/318662@main

https://bugs.webkit.org/show_bug.cgi?id=320981 Reviewed by Xabier Rodriguez-Calvar. On a device where a GStreamer seek operation leads to a pipeline async state change, we may enter a flow of internal calls that cause a second seek to zero to be executed before the first call has returned. This was detected with Spotify when performing a seek to the asset end (duration) right after playback has started from the beginning (position zero). This issue does not happen if the GStreamer seek operation does not cause a async pipeline state change. See: WebPlatformForEmbedded/WPEWebKit#1645 This patch avoids automatic playback when the video has ended (effectively helping to avoid currentTime accidentally going beyond the duration) or when a seek is still happening (avoiding currentTime to progress and change the conditions of the video). ReadyState is propagated to the player when seek has completed, helping the HTMLMediaElement algorithms to take the right decisions when seek completes. Finally, code has been added to avoid the position to ever go beyond the duration in order to avoid a degradation of the ReadyState to HaveMetadata, except when the duration is zero. This is a special case used by MediaPlayerPrivateGStreamer::duration() and MediaPlayerPrivateGStreamerMSE::duration() when the duration is unknown/unavailable, and we don't want to mess up with that and cause a stream that is just being loaded to trigger unexpected effects.

Those nodes were dropped by the assignment. They are deleted by hand, and each holds a Ref to its context, so a single dropped node leaks the whole BaseAudioContext and its graph. The loop was dead too: deleteMarkedNodes() drains m_nodesToDelete, so the condition was always false and nodes marked while deleting other nodes were never collected. Append instead of assign and loop on m_nodesMarkedForDeletion, restoring the behavior from before 6eceb6d, which drained before moving.

Coincident automation event times are legal, so an exponential ramp can have zero duration. processExponentialRamp() had no guard for that, unlike processLinearRamp(). With deltaTime == 0 the per-sample multiplier is infinite and the starting value's exponent is 0 / 0. When the event time is not frame-aligned the write cursor is already at fillToFrame, so the sample loop runs zero times -- but the trailing restore step keys off writeIndex rather than off whether the loop ran, and computes inf / inf. isEventCurrent() then skips the ramp, so the branch that would reset the value never runs; a following setTargetAtTime() writes the NaN to the output until it force-converges after 10 time constants. Guard deltaTime the way processLinearRamp() does. A zero-duration ramp has no frames left to interpolate, so the value is value2 -- which is also what WebKit already produces when the same events are frame-aligned.

…ide the source samples https://bugs.webkit.org/show_bug.cgi?id=321386 rdar://184439324 Reviewed by Chris Dumez. This patch aligns WebKit with Gecko / Firefox and Blink / Chromium. renderFromBuffer() keeps its playback position in double precision, but the reverse branch rounded that position down through floorf(), narrowing the double to float. Above 2^23 the spacing of float is 1.0, so floorf() rounds to nearest rather than down and can return a value greater than its argument: floorf(8388609.5) is 8388610. The interpolation factor derived from it on the next line is then negative, and computeSampleUsingLinearInterpolation() extrapolates past the pair of frames it is meant to be mixing between rather than interpolating between them. A read index rounded up to bufferLength also trips the bounds check at the top of the loop, breaking out and leaving the rest of the render quantum unwritten. The threshold is 2^23 frames, roughly 190 seconds at 44.1kHz. Only the reverse branch is affected; the forward branch truncates the double directly. The surrounding code already uses the double overload of floor() when computing needsInterpolation, so use std::floor() at both sites. The test renders the same content from a short buffer and from a buffer longer than 2^23 frames and requires the two to match, since playback depends only on position relative to the grain. Comparing the two rather than checking absolute sample values keeps the test independent of the interpolation or resampling filter an implementation chooses. The pattern deliberately is not a linear ramp: linearly extrapolating a linear signal happens to land on the correct value, which is why the existing negative-playbackRate tests do not catch this.

This patch aligns WebKit with Gecko / Firefox and Blink / Chromium. setBufferForBindings() returned early on a null buffer without touching m_reverb or m_buffer, so assigning null left the node fully configured with the previous impulse response. Two consequences: the attribute stopped round-tripping, since bufferForBindings() returns m_buffer and ConvolverNode.idl declares a plain nullable attribute with no custom setter, so conv.buffer = ir followed by conv.buffer = null still returned ir; and process() only zeroes its output when m_reverb is null, so the stale response kept convolving indefinitely. tailTime() and latencyTime() likewise kept reporting the old response length, holding the node in tail processing. The early return predates 2012; 103415@main only removed the adjacent ASSERT(buffer) that fired on it, leaving the clearing unimplemented. Clear m_reverb and m_buffer under m_processLock instead, which is the lock both are guarded by. The graph lock the non-null path takes is not needed here, since nothing propagates a channel count on this path. The output channel count is deliberately left alone. It was propagated downstream when the response was set, and checkNumberOfChannelsForInput() already leaves it untouched while m_buffer is null, so resetting it would reconfigure downstream nodes with no basis in the specification. Also remove the null check guarding the channel-count propagation in the non-null path, which the early return above made unreachable as false. The existing webaudio/convolver-setBuffer-null.html only set null on a fresh convolver, where m_buffer is already null, so it passed throughout. Convert it from js-test-pre.js to testharness.js so it runs in other engines, and extend it to cover the round-trip after a response is set and an offline render that must be silent afterwards. The render assertion is exact rather than thresholded, because the fixed path zeroes the bus without running the FFT. A companion assertion checks that a convolver with a response renders non-silent, so the silence check cannot pass for the wrong reason. * LayoutTests/webaudio/convolver-setBuffer-null-expected.txt: * LayoutTests/webaudio/convolver-setBuffer-null.html: * Source/WebCore/Modules/webaudio/ConvolverNode.cpp: (WebCore::ConvolverNode::setBufferForBindings): Canonical link: https://commits.webkit.org/318870@main

Follow-up to: https://bugs.webkit.org/show_bug.cgi?id=320762 This caught a previously unknown crash in getOrCreateIsolatedTree when trying to create an isolated tree for a document that's been detached from its frame. This was actually easier to hit in testing because AXObjectCache::transitionToAXThreadModeIfNeeded() iterates over every live AXObjectCache, making it more likely to randomly catch one in that state.

…dvancing the start position https://bugs.webkit.org/show_bug.cgi?id=321253 Reviewed by Yusuke Suzuki. optimizeBOL() marks the body alternatives as once-through and appends copies of the non-`^` ones as the looping set, so once-through alternatives must only be tried at the initial start position. When advancing the start position, the interpreter skipped only the first once-through alternative and resumed at the second one, so a later alternative could win over the first, e.g. /a|^x|aa/.exec("caa") returned "aa" instead of "a". The JIT emits the two sets separately and is not affected. Skip all once-through alternatives after advancing, and return NoMatch when there is no looping alternative (e.g. /^a|^b/), matching the JIT.

https://bugs.webkit.org/show_bug.cgi?id=321375 Reviewed by Simon Fraser. On a layout size change, SVGContainerLayout invalidated any gradient using relative lengths via invalidateGradient(), which nulls both m_gradient and m_attributes. The next paint then re-runs collectGradientAttributesIfNeeded() (SVGElement::synchronizeAllAttributes, serializing _every_ animated property\ to a string including the gradientTransform) and createGradient(). For an objectBoundingBox gradient this is wasted: its coordinates resolve against the object bounding box, and buildGradientIfNeeded already recomputes that userspace transform on every paint regardless of m_gradient. Only the object bounding box changed, not the gradient's own resolved data, so the cached gradient and attributes stay valid. userSpaceOnUse gradients resolve against the viewport and genuinely change with the layout size. Introduce invalidateGradientOnLayoutSizeChange(), which only repaints the gradient clients when objectBoundingBox units are used, keeping the cached gradient. * Source/WebCore/rendering/svg/RenderSVGResourceGradient.cpp: (WebCore::RenderSVGResourceGradient::invalidateGradientOnLayoutSizeChange): * Source/WebCore/rendering/svg/RenderSVGResourceGradient.h: * Source/WebCore/rendering/svg/SVGContainerLayout.cpp: (WebCore::SVGContainerLayout::layoutChildren): Canonical link: https://commits.webkit.org/318873@main

The memory cache strips the fragment identifier from HTTP URLs, so two background images differing only by fragment share one CachedResource. Style::CachedImage::equals() returned true whenever the CachedResource pointers matched, ignoring the fragment. The fragment is not cosmetic: SVGImage::drawForContainer() applies it to select the view to draw, so those two images paint differently. Comparing them equal propagated to changeRequiresRepaint(), which then skipped the repaint, leaving the old image on screen until something else invalidated the element. Only take the shared-CachedResource shortcut when the fragments also match.

Both are full applyElements() walks, O(segments) with per-curve subdivision, and Path caches neither. The accumulation loop added 2 more walks per repeat for a loop-invariant result. Inline the helper so the position and angle come from one traversal state, hoist Path::length(), and compute the end-of-path position once before the accumulation loop. That is 4 + 2 * repeatCount walks per frame down to 1, or 2 when accumulating. No behavior change. The angle now comes from a state with the same input as the one it replaces, including on failure, which the old code also read from.

…n unicode mode https://bugs.webkit.org/show_bug.cgi?id=320903 Reviewed by Yusuke Suzuki. With the /u and /v flags, YARR JIT decodes surrogate pairs for every character read. For a non-inverted character class holding only non-surrogate BMP code points, the decode is unnecessary: a surrogate code unit, a decoded non-BMP code point and errorCodePoint all lie outside of such a class, so testing the raw code unit is equivalent to testing the decoded code point. This patch reads the raw code unit for such character class terms (\w, \d, \s, [a-z], BMP-only property escapes ...) in unicode mode and lets them use the class's 64K m_table, which was disabled whenever surrogate pairs were being decoded.

There was a problem hiding this comment.
🔴 The conflict resolution in Source/JavaScriptCore/builtins/BuiltinExecutables.cpp:227 (outside GitHub's 300-file diff window) references bare isAsyncFunction, which is not in scope in the new createExecutable(..., const BuiltinSourceMetadata& scanned, ...) overload — this is an undeclared-identifier compile error on every platform. Line 223 was correctly updated to scanned.isAsyncFunction per the PR description, but line 227 was missed; change it to if (scanned.isAsyncFunction).
Extended reasoning...
What the bug is
Upstream commit 81d660ceeb2e refactored BuiltinExecutables::createExecutable() so that the source-scanning locals (hasRestParam, isAsyncFunction, parametersStart, etc.) are now computed in a separate static helper computeBuiltinSourceMetadata() and returned as a BuiltinSourceMetadata struct. The results are then passed into a new overload:
UnlinkedFunctionExecutable* BuiltinExecutables::createExecutable(VM& vm, const SourceCode& source, const BuiltinSourceMetadata& scanned, ...)The fork carries a downstream patch (from bug 304740) that bumps implementationVisibility to Private for async builtins. When re-applying that patch on top of the refactor, the merge produced this at lines 223–228:
SourceParseMode parseMode = scanned.isAsyncFunction ? SourceParseMode::AsyncFunctionMode : SourceParseMode::NormalFunctionMode;
// Async functions should have Private visibility for correct stack traces.
// See https://bugs.webkit.org/show_bug.cgi?id=304740
if (isAsyncFunction)
implementationVisibility = std::max(implementationVisibility, ImplementationVisibility::Private);Line 223 correctly reads scanned.isAsyncFunction, but line 227 was left as the bare identifier isAsyncFunction.
Why nothing brings it into scope
Verified against the source at HEAD (merge commit 6c4096e6f5):
- The only local named
isAsyncFunctionis declared at line 96 insidecomputeBuiltinSourceMetadata(), which is a separate function that returns at line 192. BuiltinExecutables.h:63definesisAsyncFunctiononly as a field ofBuiltinSourceMetadata, not as a member ofBuiltinExecutables.- The parameter list of the overload starting at line 203 does not contain it, and no local declaration between lines 203 and 227 introduces it.
- No preprocessor guard wraps line 227 — the only
#ifin the file is at line 293.
So at line 227 there is no isAsyncFunction in scope: not a local, not a parameter, not a member.
Step-by-step proof
- Compiler enters
createExecutable(VM&, const SourceCode&, const BuiltinSourceMetadata& scanned, ...)at line 203. - At line 223 it resolves
scanned.isAsyncFunction— OK, that's the struct field. - At line 227 it looks up unqualified
isAsyncFunction. Local scope: none. Parameter scope: none. Class scope (BuiltinExecutables): no such member. Namespace/global: none. - Result: error: use of undeclared identifier 'isAsyncFunction' (Clang) / error: 'isAsyncFunction' was not declared in this scope (GCC) / C2065: 'isAsyncFunction': undeclared identifier (MSVC).
Impact
This is a hard compile error that will break every build target (jsc, static libs, Bun link) on every platform (macOS, Linux glibc/musl, Windows). The PR description says the debug build succeeded and that this hunk "now reads scanned.isAsyncFunction", but the committed code at 6c4096e6f5 contradicts that — the verification build was almost certainly done before the final push, or against a working tree where line 227 had already been fixed but the fix was not staged.
Fix
Change line 227 from if (isAsyncFunction) to if (scanned.isAsyncFunction), matching line 223.

Most conflicts were the fork's quoted-include style vs upstream include churn; resolved keeping the fork style while adopting upstream's include sets. The substantive ones:
heap/HandleSet.h,assembler/ARMv7Assembler.h: deleted upstream (StrongBlock refactorff64aee116d4, ARMv7 removal6010a9ea6ce6). The fork only had include-style changes in them, so the deletions are accepted.Heap.h/Strong.h/CMakeLists.txtupdated forStrongSet.h.wtf/PlatformUse.h+interpreter/CallFrame.h: upstream removedUSE_BUILTIN_FRAME_ADDRESSentirely (2a8926009f45), deleting all the fallback paths (prepareCallOperationtopCallFrame stores,temporaryCallFrame, etc.). The fork kept the flag OFF on Windows ARM64 ("__builtin_frame_address(1) causes crashes in DFG operations", from the Windows ARM64 bring-up in January). Since the supporting fallback code no longer exists upstream, this merge takes upstream's unconditional__builtin_frame_address(1)on Windows ARM64 as well. If DFG crashes reappear on windows-aarch64, this is the first place to look; a targeted fallback would need the removed pieces restored.runtime/PageCount.h: upstream raisedMAX_ARRAY_BUFFER_SIZEfrom1ull << 32to1ull << 34; kept with the fork's commented BUN_JSC_ADDITIONS note preserved.runtime/TemporalObject.h/TemporalZonedDateTime.cpp: kept the fork'sTemporalTypeclassifier andTemporalZonedDateTime::toString(from [JSC] Expose TemporalZonedDateTime::toString and a temporalType(JSValue) classifier #393) alongside upstream's new declarations;timeZoneFromRecordnow takes upstream's renamedISO8601::ISOStringTimeZoneParseRecord.runtime/JSGlobalObject.cpp: kept upstream's newcachedLocaleCompareCollatorwhile preserving the fork's relocation ofexposeDollarVMtotools/JSDollarVM.cpp.builtins/BuiltinExecutables.cpp: the fork's async-function visibility patch now readsscanned.isAsyncFunction(upstream81d660ceeb2emoved builtin metadata computation into the generator script).cmake/WebKitMacros.cmake: took upstream's(framework STREQUAL _linked_into)form, which fixes the same empty-operand problem the fork's quoting patch addressed.cmake/OptionsJSCOnly.cmake: keptENABLE_BUN_SKIP_FAILING_ASSERTIONS; dropped the ARM32/MIPS capstone block upstream removed.Verification
