What do you think of replacing the PLATFORM(MAC) check here with a RuntimeEnabledFeatures check? This method is the only one that will require such a check – and the other PLATFORM(MAC) checks can be removed.

RuntimeEnabledFeatures should only be used as a last resort if you don't have access to the Page or Document. RuntimeEnabledFeatures is a global singleton, so does not allow for process sharing, which will no doubt bite us soon enough).

This functionality was formerly referred to as INPUT_MULTIPLE_FIELDS_UI, so maybe DateTimeMultipleFieldsUI? > Why does this need to be conditionalized at all? There are two reasons why this should be conditionalized. 1. The feature is under active development and leaves date/time inputs in a partially completed state. 2. The feature does not make sense given current iOS behaviour. On iOS, focusing on date/time inputs presents a picker in a fullscreen overlay, and individual editable fields would be inaccessible. Furthermore, iOS date/time controls have a very different appearance. That said, we could probably eventually enable this feature on iOS and make additional (platform-specific) stylesheet changes to preserve appearance, even if the functionality is inaccessible.

If we intend to keep this difference, it should be clear in the code and in the name of the conditionals. Rather than thinking about this as iOS vs. macOS, try to think about this as different behaviors. If you ever find yourself using a PLATFORM() check, really ask yourself if this is the best way to make this check. It probably isn't.

I modified the stylesheet to use "background-color: highlight;" on non-Cocoa ports. There is no concept of an accent color on other ports. I kept "background-color: -apple-system-control-accent;" on Cocoa-ports to match the appearance of system date controls.

Or is that not the point of this function? This assignment does not. However, the function should remove `DateTimeEditElement` from `element()`. I added a missing call to `InputType::destroyShadowSubtree()`. > > Source/WebCore/html/BaseChooserOnlyDateAndTimeInputType.cpp:167 > > + RefPtr<Node> node = element()->userAgentShadowRoot()->firstChild(); > > Does this need to be `RefPtr<Node>`, or can it just be `auto`? I think `auto` should be fine. > > Source/WebCore/html/shadow/DateTimeEditElement.h:72 > > + // Datetime can be represented by at most 8 fields: > > day-of-week? timezone? Day-of-week is not displayed in any of the five existing date/time controls (date, datetime-local, month, week, time). Timezone would have been necessary if `<input type=datetime>` wasn't removed from the spec. However, it is not needed for datetime-local. > > Source/WebCore/html/shadow/DateTimeNumericFieldElement.h:46 > > + void setValueAsInteger(int) override; > > NIT: should this be `final`? Modified to `final` in this patch. This is going to change in a forthcoming patch though.

Comment on attachment 407499 [details] Patch View in context: https://bugs.webkit.org/attachment.cgi?id=407499&action=review r=me, nice work! One general comment is that there's a lot of places where you could use `auto` (or `auto&`). Up to you whether to keep the explicitly written type or not, but I personally like to use `auto` for most things that are obvious from reading surrounding code :) > Source/WebCore/html/shadow/DateTimeEditElement.cpp:81 > + constexpr int countForAbbreviatedMonth = 3; > + constexpr int countForFullMonth = 4; > + constexpr int countForNarrowMonth = 5; NIT: should we move these inside the `case` for months? > Source/WebCore/html/shadow/DateTimeEditElement.cpp:108 > + return; NIT: why not replace the `break`s above with `return`? > Source/WebCore/html/shadow/DateTimeEditElement.cpp:135 > + , m_editControlOwner(makeWeakPtr(&editControlOwner)) I don't think you need the `&`.

If not, can we just make this a `FieldOwner&` instead? I'm not certain that `m_fieldOwner` cannot outlive this object. To be safe, I've kept it as a WeakPtr. > > Source/WebCore/html/shadow/DateTimeFieldElements.cpp:73 > > + setValueAsInteger(date.month() + 1); > > Does this get "transformed" back to 0-based after the user edits it? If > not, should it? We don't need to worry about it being transformed back to 0-based, since getting the full value returns a string of the form "yyyy-MM-dd" (not a DateComponents). In cases where a DateComponents is needed, the "yyyy-MM-dd" string is parsed accordingly.
