- mac: Xcode 14.0 with macOS SDK 13.0 is now required.
- Remove CefRequestHandler::OnQuotaRequest because persistent quota is no
longer supported (see https://crbug.com/1208141)
Custom global and request context preferences can now be registered via
CefBrowserProcessHandler::OnRegisterCustomPreferences. CefRequestContext
now extends CefPreferenceManager and global preferences can be accessed
via CefPreferenceManager::GetGlobalPreferenceManager.
Use ScreenWin functions to correctly compute DIP/pixel conversions for
CEF-created top-level windows.
Fix incorrect DIPToScreenRect usage in DesktopWindowTreeHostWin when
|has_external_parent_| is true.
Fix "error: use of result of assignment to object of volatile-
qualified type 'volatile gsize' (aka 'volatile unsigned long') is
deprecated [-Werror,-Wdeprecated-volatile]" when building with
use_sysroot=false on Ubuntu 18.04.
This service is required by the "PermissionOnDeviceNotificationPredictions"
feature which is enabled by default in https://crbug.com/1350956. It uses a
Google backend service as described at https://go.dev/solutions/google/chrome.
This change removes the usage of PredictionBasedPermissionUiSelector, which
triggered this dependency, along with related startup complexity that was added
to support the optimization/prediction service in the M106 update.
DesktopWindowTreeHostWin ("Chrome_WidgetWin_0") focus needs to be set before
the associated call to WebContents::Focus. In the case of mouse click events,
this means ::SetFocus needs to be called explicitly. See updated comments in
CefBrowserPlatformDelegateNativeWin::SetFocus.
- Windows: SDK version 10.0.20348.0 is now required.
- MacOS: SDK version 12.3 (Xcode 13.3) is now required.
- Legacy swiftshader binaries (`swiftshader/*` on Win/Linux and
`libswiftshader_*.dylib` on MacOS) have been removed (see issue #3176).
All file dialogs irrespective of source, platform and runtime will now be
routed through CefFileDialogManager and trigger CefDialogHandler callbacks
(see issue #3293).
Adds Chrome runtime support for CefBrowserHost::RunFileDialog and
CefDialogHandler callbacks.
Adds Alloy runtime support for internal GTK file and print dialogs on Linux
subject to the following limitations:
1. Internal GTK implementation:
- Cannot be used with multi-threaded-message-loop because Chromium's
internal GTK implementation is not thread-safe (does not use GDK threads).
- Dialogs will not be modal to application windows when used with off-screen
rendering due to lack of access to the client's top-level GtkWindow.
2. Cefclient CefDialogHandler implementation:
- Cannot be used with Views because it requires a top-level GtkWindow.
Due to the above limitations no dialog implementation is currently provided for
Views + multi-threaded-message-loop on Linux. In cases where both
implementations are supported the cefclient version is now behind an optional
`--use-client-dialogs` command-line flag.
Expressly forbids multiple simultaneous file dialogs with the internal platform
implementation which uses modal dialogs. CefDialogHandler will still be notified
and can optionally handle each request without a modal dialog (see issue #3154).
Removes some RunFileDialog parameters that are not supported by the Chrome file
dialog implementation (selected_accept_filter parameter, cef_file_dialog_mode_t
overwrite/read-only flags).
This change adds Chrome runtime support on Windows and Linux for creating a
browser parented to a native window supplied by the client application.
Expected API usage and window behavior is similar to what already exists with
the Alloy runtime. The parent window handle should be specified by using
CefWindowInfo::SetAsChild in combination with the CefBrowserHost::CreateBrowser
and CefLifeSpanHandler::OnBeforePopup callbacks.
The previously existing behavior of creating a fully-featured Chrome browser
window when empty CefWindowInfo is used with CreateBrowser remains unchanged
and Views is still the preferred API for creating top-level Chrome windows
with custom styling (e.g. title bar only, frameless, etc).
The cefclient Popup Window test with a native parent window continues to crash
on Linux with both the Alloy and Chrome runtimes (see issue #3165).
Also adds Chrome runtime support for CefDisplayHandler::OnCursorChange.
To test:
- Run `cefclient --enable-chrome-runtime [--use-views]` for the default (and
previously existing) Views-based behavior.
- Run `cefclient --enable-chrome-runtime --use-native` for the new native
parent window behavior.
- Run `cefclient --enable-chrome-runtime --use-native --no-activate` and the
window will not be activated (take input focus) on launch (Windows only).
- Run `cefclient --enable-chrome-runtime [--use-views|--use-native]
--mouse-cursor-change-disabled` and the mouse cursor will not change on
mouseover of DOM elements.
This change configures session restore behavior for the NEXT application
restart by setting the "session.restore_on_startup" preference based on the
[CefSettings|CefRequestContextSettings].persist_session_cookies value.
This change adds a CefDownloadHandler::CanDownload callback for optionally
blocking user-initiated downloads (e.g. alt + link click or link click that
returns a `Content-Disposition: attachment` response from the server).
To test:
- Run `ceftests --gtest_filter=DownloadTest.*`.
- Run `cefclient --hide-controls`. User-initiated downloads will be blocked.
This change adds a CefCommandHandler::OnChromeCommand callback for optionally
handling Chrome commands triggered via menus or keyboard shortcuts. Supported
command IDs are listed in a new cef_command_ids.h header file.
To test: Run `cefclient --enable-chrome-runtime --hide-controls`. Most commands
will blocked and removed from context menus.
This change adds `CefBrowserSettings.chrome_status_bubble` for controlling
whether the Chrome status bubble will be used.
Testable in cefclient by passing the `--hide-chrome-status-bubble`
command-line flag.
We need to override ChromeMimeHandlerViewGuestDelegate to handle
OnGuestAttached/Detached callbacks in order to account for the guest renderer
process hosting the PDF extension.
Additional work will be required to account for the renderer process hosting the
PDF viewer when using `--enable-features=PdfUnseasoned` (see issue #2969).
- Remove CefRequestContextHandler::OnBeforePluginLoad and
CefRequestContext::PurgePluginListCache (fixes issue #3047). These methods
stopped being relevant after the removal of Flash support in January 2021.
The last remaining PPAPI plugin (PDF viewer) will switch to a non-plugin
implementation in the near future (see https://crbug.com/702993#c58) and
functionality related to plugin filtering has already been removed in
https://crrev.com/343ae351c9.
To test:
Run `cefclient.exe --use-views --hide-frame --hide-controls`
Add `--enable-chrome-runtime` for the same behavior using the Chrome location
bar instead of a text field.
Widevine CDM binaries will be downloaded on supported platforms shortly after
application startup. Widevine support will then become available within a few
seconds after successful installation on Windows or after the next application
restart on other platforms. The CDM files will be downloaded to a "WidevineCdm"
directory inside the `CefSettings.user_data_path` directory.
Pass the `--disable-component-update` command-line flag to disable Widevine
download and installation. Pass the `--component-updater=fast-update` command-
line flag to force Widevine download immediately after application startup.
See the related issue for additional usage details.
This change adds a minimal implementation of the |tabs.update| extension API and
modifies StreamsPrivateAPI::SendExecuteMimeTypeHandlerEvent to return a valid
|streamInfo.tabId| value as required by the navigateInCurrentTab implementation
in chrome/browser/resources/pdf/browser_api.js.
This change introduces a few minor CEF API behavior changes:
- A CefProcessMessage object cannot be reused after being passed to
SendProcessMessage.
- The |extra_info| argument to CefRenderProcessHandler::OnBrowserCreated may
now be NULL.
Where appropriate, we now utilize the default UTF string encoding format and
shared memory to reduce copies and conversions for the cross-process
transfer of arbitrary-length strings. For example, CefFrame::GetSource/GetText
now involves zero UTF conversions and zero copies in the browser process for
the CefString delivered to CefStringVisitor::Visit().
The policy->CanAccessDataForOrigin CHECK in NavigationRequest::
GetOriginForURLLoaderFactory was failing because unregistered schemes
(which are already considered non-standard schemes) didn't trigger the
registered non-standard scheme allowance that we previously added in
ChildProcessSecurityPolicyImpl::CanAccessDataForOrigin. This change
modifies GetOriginForURLLoaderFactory to always return an opaque/unique
origin for non-standard schemes resulting in unregistered and non-standard
schemes receiving the same treatment.
New test coverage has been added for this condition, and can be run with:
ceftests --gtest_filter=CorsTest.*CustomUnregistered*
Profile::IsIncognitoProfile() currently returns false for CEF incognito profiles
because they are not the primary OTR profile. At the same time, we don't
necessarily want IsIncognitoProfile() to return true for CEF profiles because,
among other things, that causes the BrowserView to apply the dark toolbar theme.
Instead, this change updates ProfileMenu expectations to support the CEF
incognito profiles without otherwise modifying the incognito behavior.
Note that the IsIncognitoProfile() implementation has recently changed in
https://crrev.com/7bf6eb2497 and the conclusions in this commit will likely need
to be revisited in an upcoming Chromium update.
The Chrome runtime requires that cookieable scheme information be available
at Profile initialization time because it also triggers NetworkContext creation
at the same time. To make this possible, and to avoid various race conditions
when setting state, the cookieable scheme configuration has been added as
|cookieable_schemes_list| and |cookieable_schemes_exclude_defaults| in
CefSettings and CefBrowserContextSettings. The CefCookieManager::
SetSupportedSchemes and CefBrowserProcessHandler::GetCookieableSchemes methods
are no longer required and have been removed.
This change also modifies chrome to delay OffTheRecordProfileImpl initialization
so that |ChromeBrowserContext::profile_| can be set before
ChromeContentBrowserClientCef::ConfigureNetworkContextParams calls
CefBrowserContext::FromBrowserContext to retrieve the ChromeBrowserContext
and associated cookieable scheme information. Otherwise, the
ChromeBrowserContext will not be matched and the NetworkContext will not be
configured correctly.
The CookieTest suite now passes with the Chrome runtime enabled.
