CefWindowImpl::CanHandleAccelerators was returning false for
accelerators triggered in the overlay BrowserView due to
IsWindowKey (called from NativeWidgetMac::IsActive) returning
false. View::CanHandleAccelerators, on the other hand, only
checks IsActive for Aura (non-MacOS) windows. We therefore
delegate to the View implementation for consistent handling.
When running with the overlay Browser enabled (`--show-overlay-browser`),
pressing Alt+O will move the overlay Browser to a new top-level Window.
Pressing Alt+O again or closing the new Window via the close button will
return the Browser to the overlay. Closing the Browser via `window.close()`
(in the new Window or overlay) will dismiss the overlay completely as
required to maintain consistent internal state. Detection of this state is
supported by the new CefBrowserHost::IsReadyToBeClosed method.
Draggable regions in the main Browser are updated to account for the
presence or absence of the overlay Browser. Support for draggable regions
in the overlay Browser in not implemented in cefclient.
Behavior with multiple overlays, `window.close()` and draggable regions
can be tested by adding `--hide-frame --hide-controls`.
TryCloseBrowser should potentially trigger JavaScript unload handlers
and return false. Add CefBrowserHost::IsReadyToBeClosed for detecting
mandatory close state. Enable, for Chrome style browsers, LifeSpanTest
that don't require DoClose(). Update related documentation.
Avoid a circular ownership dependency between CefBrowserViewImpl and
CefBrowserPlatformDelegate[Chrome]Views (owned by CefBrowserHostBase).
Trigger CefBrowserHostBase destruction when the last CefBrowserViewImpl
reference is released.
This fixes a number of shutdown crashes related to overlay CefBrowsers
still existing at CefShutdown.
Adds new `--show-overlay-browser` command-line flag that creates an
overlay containing an Alloy-style BrowserView. The main BrowserView
may be Chrome- (default) or Alloy-style (add `--use-alloy-style`).
This overlay will only be added to standalone (non-popup) windows.
Popups triggered via the overlay will receive standard Alloy-style
handling in cefclient (e.g. Views-hosted window). Add
`--use-default-popup` for default popup handling.
ChromeCommandDispatcherDelegate forwards accelerator events to
the FocusManager through NativeWidgetMacNSWindowHost::
HandleAccelerator. Always initialize it so that accelerators also
work in a CefWindow without a BrowserView.
Some downloaded file types [1] default to opening in a Browser. Open
requests for these file types originating from the Download bubble UI
should route to the source Browser (call OnOpenURLFromTab). If
OnOpenURLFromTab is unhandled proceed with the default Chrome behavior
of opening the URL in a new default Browser.
[1] PDF, html, etc. For the complete list of file types see
ChromeDownloadManagerDelegate::IsOpenInBrowserPreferredForFile.
When the V8 sandbox is enabled, ArrayBuffer backing stores must be
allocated inside the sandbox address space. This change introduces a new
CefV8Value::CreateArrayBufferWithCopy method that copies the memory
contents into the sandbox address space.
Enabling the V8 sandbox can have a performance impact, especially when
passing large ArrayBuffers from C++ code to the JS side. We have therefore
retained the old CefV8Value::CreateArrayBuffer method that references
external memory. However, this method can only be used if the V8 sandbox is
disabled at CEF/Chromium build time.
To disable the V8 sandbox add `v8_enable_sandbox=false` to
`GN_DEFINES` when building CEF/Chromium.
The InterceptedRequestHandlerWrapper object may be deleted (likely via
~InterceptedRequest) while the task to call
InterceptedRequestHandlerWrapper:ContinueCreateURLLoaderNetworkObserver
is still pending. That binding holds a
WeakPtr<InterceptedRequestHandlerWrapper> (which is now nullptr)
resulting in the bound std::unique_ptr<PendingRequest> being deleted
while still holding a raw_ptr<network::ResourceRequest> to the
already-deleted object. This is always safe (raw_ptr will never be
dereferenced) because of the WeakPtr check.
Found using a CEF build with clang_use_chrome_plugins=true
and treat_warnings_as_errors=false.
This change rewrites remaining raw pointers reported by
chromium-rawptr checker and fixes a build error reported
by StackAllocatedChecker.
