  84         [GTK][AC] Resizing the window doesn't always update the visible rect
  85         https://bugs.webkit.org/show_bug.cgi?id=189743
  86
  87         Reviewed by Michael Catanzaro.
  88
  89         Disassociate resizing that can be done on an AcceleratedSurface object
  90         between "host resizes" and "client resizes".
  91
  92         The former is done from ThreadedCoordinatedLayerTreeHost directly, and
  93         is currently used only for GTK on X11, where a new pixmap object is
  94         created on each resize, which affects the context ID that is based on
  95         that pixmap object's address.
  96
  97         The latter is done from the composition thread. It's used for GTK on
  98         Wayland and WPE. In both cases, the underlying window object does not
  99         change on each resize, but it's necessary to perform the actual resize
 100         on the composition thread.
 101
 102         So far it hasn't been performed there, which ended up pushing sizes of
 103         the WebKit view and the underlying window object out of sync during
 104         resizing, leaving parts of window unrendered.

 276
 277         When the network process serializes certificate data to other
 278         processes through the argument coders, the certificate chain, if
 279         present, is lost. In practice this means that applications using
 280         the public API to process certificate info have no details on the
 281         certificate chain, other than the very basics included in the

 410         Reviewed by Tim Horton.
 411
 412         Fixes the bug by refactoring datalist suggestion information on iOS; currently, we override text suggestions on
 413         _WKFormInputSession. This only works for a few internal clients (including Safari) that set a _WKInputDelegate
 414         and also implement either -_webView:willStartInputSession: or -_webView:didStartInputSession:, which is
 415         necessary in order to ensure that WebKit creates and maintains a form input session.
 416
 417         The two pieces of information that datalist code needs to vend to WKContentView are a list of UITextSuggestions
 418         and a custom input view, which are both currently properties of _WKFormInputSession. This patch lifts these out
 419         of the input session and makes them properties of WKContentView, which are used in
 420         WebDataListSuggestionsDropdownIOS.
 421
 422         Test: fast/forms/datalist/datalist-textinput-suggestions-order.html
 423
 424         * UIProcess/ios/WKContentViewInteraction.h:
 425         * UIProcess/ios/WKContentViewInteraction.mm:
 426
 427         Add new properties to WKContentView: an input view for datalist suggestions, and a list of text suggestions.

 433
 434         Pull out common logic when resigning first responder or tabbing to the next or previous text field into a new
 435         helper. This helper notifies `_inputPeripheral`, `_formInputSession`, and `_dataListTextSuggestionsInputView`
 436         when editing has ended; the input peripheral and suggestions input view use this chance to send the value of the
 437         form control to the web process.
 438
 439         (-[WKContentView resignFirstResponderForWebView]):
 440         (-[WKContentView inputView]):
 441
 442         If a custom input view is not set but we have an input view for a datalist's text suggestions, use the datalist
 443         input view.
 444
 445         (-[WKContentView accessoryTab:]):
 446         (-[WKContentView _stopAssistingNode]):
 447
 448         Clear datalist state on WKContentView.

 453         (-[WKContentView setDataListTextSuggestions:]):
 454         (-[WKContentView updateTextSuggestionsForInputDelegate]):
 455
 456         Pull out logic for setting suggestions on UIKit's `inputDelegate` (i.e. UIKeyboardImpl). We now first consult
 457         internally-vended text suggestions from _WKFormInputSession; if an internal client has not overridden our text
 458         suggestions, then we simply use suggestions from the current datalist (if present).
 459
 460         * UIProcess/ios/WebDataListSuggestionsDropdownIOS.mm:
 461         (-[WKDataListSuggestionsPicker updateWithInformation:]):
 462         (-[WKDataListSuggestionsPicker showSuggestionsDropdown:activationType:]):

 465         (-[WKDataListSuggestionsPopover showSuggestionsDropdown:activationType:]):
 466         (-[WKDataListSuggestionsPopover didSelectOptionAtIndex:]):
 467
 468         Change all the places that currently manipulate WKContentView's form input session to directly set text
 469         suggestions and the text suggestion input view on the content view instead.

 479         This patch adds the following:
 480         - The WebProcessPool now tells the WebsiteDataStore when a network process has
 481             been created.
 482         - The WebsiteDataStore in turn tells the WebResourceLoadStatisticsStore when
 483             a network process has been created.
 484         - The WebResourceLoadStatisticsStore makes sure to update the network processes
 485             with its cookie policy when it's notified that a network process has been
 486             created.
 487
 488         In addition, this patch changes the following:
 489         - The ResourceLoadStatisticsMemoryStore no longer keeps track of which domains
 490             it has told the network process to block cookies for. The reason is that
 491             we cannot assume that there is only one network process so we should
 492             always send complete blocking data.
 493         - The ResourceLoadStatisticsMemoryStore's functions for communicating cookie
 494             blocking state to the network process no longer take and forward the
 495             "clear first" parameter. This is because complete data is sent every time
 496             and thus the network process' set is always cleared on an update.
 497         - Removes WebsiteDataStore::networkProcessDidCrash() and
 498             WebResourceLoadStatisticsStore::scheduleCookieBlockingStateReset() since
 499             the call site---WebProcessPool::ensureNetworkProcess()---now calls
 500             WebsiteDataStore::didCreateNetworkProcess() after a network process
 501             crash and the state sync for cookie blocking is triggered.

 608         Reviewed by Tim Horton.
 609
 610         Before this patch, to make an asynchronous IPC message with a reply you had to find two objects that
 611         can talk to each other, make two new message types, send a generated identifier, keep track of that
 612         identifier, make a HashMap somewhere to store the object waiting for the response, and hook it all up.
 613         What a mess.  No wonder people take shortcuts and make strange design decisions.
 614
 615         Now, you can just use a CompletionHandler and mark the reply as Async in *.messages.in.
 616         I've adopted this with a message whose behavior is covered by the storage/indexeddb/modern/blob-cursor.html

1401         <rdar://problem/45354095>
1402
1403         Reviewed by Antti Koivisto.
1404
1405         Cap number of SuspendedPageProxy objects to 3 to avoid accumulating too many "suspended" processes.
1406
1407         Also allow a WebPageProxy to have more than one SuspendedPageProxy so that PageCache now works for
1408         more than 1 history navigation (up to 3 with the suspended page limit in this patch).
1409
1410         The following cleanup / refactoring was made to support this:
1411         - The SuspendedPageProxy objects are now owned by the WebProcessPool instead of the WebPageProxy.
1412           The WebProcessPool is in charge of limiting the number of SuspendedPageProxy objects by dropping
1413           the oldest one whenever a WebPageProxy tries to add a new one and we've already reached the limit.
1414         - WebProcessProxy no longer needs to know anything about suspended pages, which simplifies the
1415           code quite a bit. Instead, the SuspendedPageProxy objects now register themselves as
1416           IPC::MessageReceivers with their WebProcessProxy. The SuspendedPageProxy also take care of
1417           calling maybeShutdown() on their WebProcessProxy when they get destroyed.

1738         The test is doing the following:
1739         > document.execCommand("Delete"); document.execCommand("Undo");
1740
1741         Both operation are synchronous and rely on synchronous IPC from the WebProcess to the UIProcess.
1742         However, for the undo operation to succeed, the first command need to have been registered with
1743         with the UIProcess via the WebPageProxy::RegisterEditCommandForUndo IPC to the UIProcess, which
1744         is asynchronous.
1745
1746         After r236512, the UIProcess no longer processes incoming sync / async IPC in order and thus,
1747         it is possible for the WebPageProxy::ExecuteUndoRedo synchronous IPC to get processed by the
1748         UIProcess *before* the WebPageProxy::RegisterEditCommandForUndo asynchronous IPC for the
1749         previous "Delete" command. As a result, canUndo would return false and we would fail to undo.
1750
1751         To address the issue, use SendOption::DispatchMessageEvenWhenWaitingForSyncReply flag when sending
1752         the WebPageProxy::RegisterEditCommandForUndo IPC, so that it gets processed in order with regards

1874         In r230686, we switched from using UIWKSelectionAssistant to UIWKTextInteractionAssistant for handling selection
1875         in non-editable content on iOS; as such, when an editable element loses focus, instead of switching from the
1876         text interaction assistant to the web selection assistant as we've previously done, we now reset our text
1877         interaction assistant by calling `-[UIWKTextInteractionAssistant setGestureRecognizers]`, which removes all of
1878         the current text selection gesture recognizers from WKContentView and regenerates them by building up a tree of
1879         `UITextInteraction`s and adding them to the assistant (see `-[UITextInteractionAssistant
1880         addGestureRecognizersToView:]`). In particular, `_UITextSelectionForceGesture` is the gesture recognizer used to
1881         trigger text selection when long pressing.
1882
1883         After dismissing the keyboard by tapping the "Done" button, the UITextInteractions and gesture recognizers on
1884         the interaction assistant include:
1885
1886             <UITextInteraction>
1887                 …
1888                 <UITextIndirectNonEditableInteraction>
1889                     <_UIKeyboardBasedNonEditableTextSelectionInteraction>
1890                       ↳ "_UIKeyboardTextSelectionGestureForcePress" → <_UITextSelectionForceGesture>
1891
1892         However, after the keyboard dismisses due to an editable element losing focus, the UITextInteractions on the
1893         interaction assistant look like this:
1894
1895             <UITextInteraction>
1896                 …
1897                 <UITextIndirectNonEditableInteraction>
1898
1899         Subsequently, the lack of a `_UIKeyboardBasedNonEditableTextSelectionInteraction` makes text selection by long
1900         pressing impossible, since the `_UITextSelectionForceGesture` is never introduced to `WKContentView`. In UIKit,
1901         `UITextIndirectNonEditableInteraction` only adds `_UIKeyboardBasedNonEditableTextSelectionInteraction` as a
1902         child if the text input view — in our case, WKContentView — is missing an input delegate (see `-initWithView:`).
1903         In the case where the Done button is used to dismiss the keyboard, WKContentView loses first responder, and the
1904         input delegate of WKContentView is cleared out early on, before we call `-stopAssistingKeyboard`:
1905
1906             -[WKContentView(WKInteraction) setInputDelegate:]
1907             -[UIKeyboardImpl setDelegate:force:]
1908             -[UIPeripheralHost(UIKitInternal) _reloadInputViewsForResponder:]
1909             -[UIResponder _finishResignFirstResponder]
1910             -[UIResponder resignFirstResponder]
1911             -[WKContentView(WKInteraction) resignFirstResponderForWebView]
1912             -[UIKeyboardImpl dismissKeyboard]
1913
1914         However, in the case where the focused element is blurred, we end up clearing out the delegate in
1915         `-_stopAssistingNode`, *after* we've already called `-setGestureRecognizers` on the interaction assistant. This
1916         means UIKit will skip adding `_UIKeyboardBasedNonEditableTextSelectionInteraction` to the text interaction
1917         assistant.
1918
1919             -[WKContentView(WKInteraction) setInputDelegate:]
1920             -[UIKeyboardImpl setDelegate:force:]
1921             -[UIPeripheralHost(UIKitInternal) _reloadInputViewsForResponder:]
1922             -[UIResponder(UIResponderInputViewAdditions) reloadInputViews]
1923             -[WKContentView(WKInteraction) _stopAssistingNode]
1924
1925         To fix this, we simply reset our `inputDelegate` earlier in `_stopAssistingKeyboard` instead of waiting until
1926         we reload input views. This ensures that UIKit sets up the text interaction assistant's gestures when changing
1927         focus in the same way as we would when the keyboard is dismissed via `-resignFirstResponder` (e.g. when pressing
1928         the Done button).

1950         When the inspector is placed next to the web view it uses its _topContentInset and _totalHeightOfBanners
1951         to lay out the inspector so it does not underlap the window toolbar, but this technique does not work when
1952         in responsive design mode because of the different attachment view. This patch fixes the issue by using
1953         -[NSWindow contentLayoutRect] to figure out the height of the inspector instead of relying on the content
1954         insets of the web view. This requires observing -contentLayoutRect and ensure we only observe its changes

1991         be a factor of the view size; this allows internal clients to change page zoom levels on iOS. Currently,
1992         changing the page zoom level automatically zooms to the new initial scale only if the user has not manually
1993         scaled the page before, even if the page is already at initial scale (e.g. after the user double taps to zoom on
1994         a small element, and double taps again to zoom back out to initial scale).

2084         [GTK][WPE] Implement subprocess sandboxing
2085         https://bugs.webkit.org/show_bug.cgi?id=188568
2086
2087         Reviewed by Michael Catanzaro.
2088
2089         This implements sandboxing of WebKitWebProcesses.
2090
2091         The sandbox is opt-in at runtime as it is a behavior change.
2092         See webkit_web_context_set_sandbox_enabled() and the
2093         WEBKIT_FORCE_SANDBOX env var for developers.
2094
2095         This is Linux specific using Namespaces, Seccomp, and a DBus proxy service.
2096         This introduces three new dependencies:
2097
2098         - bwrap executable
2099         - libseccomp library
2100         - xdg-dbus-proxy executable
2101
2102         The use of xdg-dbus-proxy will ideally be replaced once upstream DBus
2103         gains the same filtering abilities which is a work in progress.
2104
2105         Currently the sandbox is not completed and there are a few large holes:
2106
2107         - Pulseaudio: The Pipewire project will solve this.
2108         - DRI device access: No immediate solutions planned.
2109         - Webcam device access: Pipewire will also solve this.
2110         - Webprocess network access: Will require GStreamer changes.
2111         - DConf access: Custom proxy planned.
2112         - X11 access: Wayland solves this.
2113
2114         That is not an exhaustive list but are the noteworthy ones. Filesystem access
2115         is still an evolving list as problems are found as is specific DBus name access.

2324         Add support for _setViewScale: and _viewScale on iOS. While similar in concept to macOS, changing this property
2325         on iOS uses viewport configurations to change the minimum layout size of the document and apply view scaling.
2326         Setting the view scale on iOS to a value `s` multiplies the minimium layout size by a factor `1 / s`, but also
2327         multiplies the initial, minimum and maximum scales by a factor of `s`. The net effect of applying this scale
2328         causes the page to lay out at a larger width and shrink (or a smaller width and expand) to fit the viewport.

2616         [GTK][WPE] Add mediaDevices.enumerateDevices support
2617         https://bugs.webkit.org/show_bug.cgi?id=185761
2618
2619         Reviewed by Youenn Fablet.
2620
2621         Implemented the enumerateDevices API using a new WebKit class
2622         (DeviceIdHashSaltStorage) that generates and stores the device ids
2623         hash salts per origin, used to avoid fingerprinting in the
2624         webpages.
2625
2626         The patch also adds a new type of data for the WebsiteDataStore.
2627         That way the users can call the WebsiteDataStore to show what
2628         origins have hash salt generated and remove them at some point.
2629
2630         For the moment just GTK+ and WPE ports are using this class to
2631         generate the hash salts. The patch adds code to the
2632         checkUserMediaPermissionForOrigin API implementation, it was empty
2633         until now for these ports. In this function we create an instance
2634         of a new class WebKitDeviceInfoPermissionRequest that implements
2635         the WebKitPermissionRequestIface interface, that allows the ports
2636         to use the current permission managers implemented in the
2637         embedders to handle this new kind of request the way they like
2638         it. The default implementation is deny.
2639
2640         The class WebKitDeviceInfoPermissionRequest takes care of
2641         contacting the DeviceIdHashSaltStorage and request/regenerate the
2642         hash salts accordingly.
2643
2644         Persistency is still not implemented, we will add it in a
2645         future patch.

2655         the policies regarding the hash salts when the embedder allows or

2751
2752         There's a race in WKKeyboardScrollingAnimator that's exacerbated by HIDEventGenerator
2753         being much faster than a human finger. We get our "begin" events from interpretKeyEvent,
2754         after the Web Content process has had its way with it, but currently the
2755         back-channel "handle" events (e.g. for key up, which doesn't go to interpretKeyEvent)
2756         are retrieved from handleKeyWebEvent in the UI process, which is *before*
2757         the Web Content process has had a swing at it.
2758
2759         If you lose the race (an insanely short tap like you get from HIDEventGenerator,
2760         or with a very busy Web Content process), we see handle(keyDown), handle(keyUp), begin(keyDown),
2761         and get stuck scrolling!
2762
2763         Instead, retrieve the out-of-band "handle" events from _didHandleKeyEvent,
2764         so that they're sensibly and strictly ordered with respect to the timing of interpretKeyEvent/"begin".

2872
2873         When process swapping and "suspending" the previous WebProcess in a SuspendedPageProxy,
2874         we need to keep around the main frame's ID that still exists on in this process. This
2875         is needed so that we can re-create a UI-side WebFrameProxy for the WebFrame that exists
2876         in the WebProcess, if we ever swap back to this suspended process (see login in
2877         WebPageProxy::swapToWebProcess()).
2878
2879         The bug was that the main frame ID was stored on the WebPageProxy via m_mainFrameID instead of the
2880         SuspendedPageProxy. This means that m_mainFrameID would get overriden when navigating in the new
2881         WebProcess with the value 1 (because WebFrame identifiers start at 1 and are per-WebProcess).
2882         This would lead to us constructing a WebFrameProxy with the wrong frame identifier in
2883         WebPageProxy::swapToWebProcess(), which would override an existing unrelated WebFrame in the
2884         WebProcessProxy's HashMap of frames. This would lead to crashes later on as the WebFrame
2885         would not be associated to the WebPageProxy we expect.

3253
3254         Some users have reported that Cmd-A for Select All no longer works in safaridriver.
3255         Instead, this hangs the session. This happens because the WebAutomationSession class
3256         assumes that each call to simulateKeyboardInteraction causes keyboard events to be processed,
3257         but in corner cases like Cmd-A, some events that we simulate are swallowed by AppKit and
3258         never make it back to WebKit. Because the session never gets the "keyboard events flushed"
3259         callback, it assumes the interaction is still ongoing, and never returns, causing a hang.
3260
3261         This patch consists of two parts:
3262          - Add logging of important state changes and events when simulating user input.
3263          - Make code more robust when simulating key actions that generate no events on macOS.

3321         Reviewed by Simon Fraser.
3322
3323         Introduce WKKeyboardScrollViewAnimator, which wraps WKKeyboardScrollingAnimator
3324         and provides a reasonable set of default behaviors for UIScrollView.
3325         This is the first step on the way to WKKeyboardScrollingAnimator
3326         being platform- and toolkit-agnostic, and helps avoid adding a whole
3327         bunch of code to WKContentView.
3328
3329         Adopt UIKit's scroll-to-top animation curve for whole-document scrolls.
3330
3331         Adjust WKKeyboardScrollingAnimator's physics; it now simulates a spring
3332         attached to the page when decelerating. When a key is pressed, it applies
3333         a constant force to the page (up to some maximum velocity). When released,
3334         the spring causes the page to decelerate smoothly.
3335
3336         Add rubber-banding to keyboard scrolling, based on the same spring that
3337         decelerates the page.
3338
3339         Remove the initial bounce on keydown before starting the smooth scroll.
3340
3341         Remove arrow key commands from WKContentView; this avoids double-processing
3342         incoming arrow key events, makes the event stream make more sense, and was
3343         entirely unnecessary.
3344
3345         * Platform/spi/ios/UIKitSPI.h:
3346         Add a wide variety of useful SPI.
3347

3359         manipulate a UIScrollView) instead of a WKKeyboardScrollingAnimator
3360         (which requires its clients to implement everything in terms of an
3361         abstract interface.
3362
3363         (-[WKContentView scrollViewWillStartPanOrPinchGesture]):
3364         Inform the keyboard scrolling animator that the user is going to start
3365         an interactive gesture that needs control of the scroll view, so it
3366         can stop its current animated scroll.

3405         for the lifetime of the scroll (including the force applied, maximum
3406         velocity, etc.) and return them together.
3407

3409         Use the scrollable's native scroll-to-extent animation (e.g. UIScrollView's
3410         scroll-to-top curve) for whole-document scrolls.

3418         point given the system's current energy, unless that stopping point is
3419         less than one increment from the starting point. In that case, we attach

3701         [iOS] [WK2] Expose some more editing SPI on WKWebView
3702         https://bugs.webkit.org/show_bug.cgi?id=190232

3704
3705         Reviewed by Tim Horton.
3706
3707         Exposes a few additional editing commands as SPI on WKWebView, by defining a new extension on WKWebView that
3708         also conforms to <UIResponderStandardEditActions>. This patch implements nearly all of the remaining
3709         unimplemented methods on UIResponderStandardEditActions, and the new extension augments this set of editing
3710         methods by adding additional editing helpers that don't currently exist on iOS (e.g. toggleStrikeThrough and
3711         insertUnorderedList). The names of these new methods have been largely been borrowed from their counterparts on
3712         macOS (see: `NSResponder.h`).
3713
3714         The new edit actions are added in this patch on iOS are:
3715
3716         ```
3717         - (void)alignCenter:(id)sender;
3718         - (void)alignJustified:(id)sender;
3719         - (void)alignLeft:(id)sender;
3720         - (void)alignRight:(id)sender;
3721         - (void)indent:(id)sender;
3722         - (void)insertOrderedList:(id)sender;
3723         - (void)insertUnorderedList:(id)sender;
3724         - (void)outdent:(id)sender;
3725         - (void)toggleStrikeThrough:(id)sender;
3726         - (void)setFont:(UIFont *)font sender:(id)sender;
3727         - (void)setFontSize:(CGFloat)fontSize sender:(id)sender;

3744         way as we currently treat bold, italic and underline: that is, they are enabled only when the user is in a

3934
3935         WebAutomationSession::terminate() can be called at any time to nuke the session.
3936         However, it's possible that the session is in the midst of simulating keyboard/mouse
3937         events. While in that state, there are some CompletionHandler objects waiting
3938         for key/mouse events to be flushed. We need to empty out callback maps with
3939         CompletionHandler instances so that they do not assert because they were never called.
3940
3941         I was able to test this manually by running a test that erroneously hangs
3942         while waiting for keyboard input. While the test was hung, I killed the NetworkProcess
3943         manually to trigger WebAutomationSession::terminate(). From there, I saw that the
3944         Perform Actions REST API call gets cancelled with the appropriate error code.
