This change adds support for CEF settings configuration of accept_language_list.
If specified, this value will take precedence over the "intl.accept_languages"
preference which is controlled by chrome://settings/languages.
With the Chrome runtime, Profile initialization may be asynchronous. Code that
waited on CefBrowserContext creation now needs to wait on CefBrowserContext
initialization instead.
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*
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.
GTK3 is required by the Chrome runtime. The cefclient off-screen rendering
example no longer works with Ubuntu 16.04. With end-of-life in April 2021
we are dropping support for 16.04 in the near future in any case.
The Chrome browser can now be hosted in a Views-based application on Mac
(see issue #2969).
To launch a fully-featured Chrome window using cefsimple:
$ open cefsimple.app --args --enable-chrome-runtime
To launch a minimally-styled Views-hosted window using cefsimple:
$ open cefsimple.app --args --use-views [--enable-chrome-runtime]
To launch a fully-styled Views-hosted window using cefclient:
$ open cefclient.app --args --use-views [--enable-chrome-runtime]
Known issues:
- Some Views unit tests are currently failing on Mac.
The Chrome browser can now be hosted in a Views-based application on Windows
and Linux.
To launch a fully-featured Chrome window using cefsimple:
$ cefsimple --enable-chrome-runtime
To launch a minimally-styled Views-hosted window using cefsimple:
$ cefsimple --enable-chrome-runtime --use-views
To launch a fully-styled Views-hosted window using cefclient:
$ cefclient --enable-chrome-runtime --use-views
Views unit tests also now pass with the Chrome runtime enabled:
$ ceftests --gtest_filter=Views* --enable-chrome-runtime
Known issues:
- Popup browsers cannot be intercepted and reparented.
- Only install network intercepts for Profiles that have an associated
CefBrowserContext. For incognito windows the CefBrowserContext is
associated with the OffTheRecordProfileImpl's original Profile.
- cefsimple: Return the default CefClient instance for browser windows
created via the Chrome UI, and allow Chrome to show error pages.
Switch to using g_main_context_default() in MainMessageLoopMultithreadedGtk. As of M86
(https://crrev.com/b960daf4e6) Chromium now creates its own context in MessagePumpGlib so
we can use the default context in cefclient. This is also more "correct" from a GTK usage
perspective. As part of this change all GTK dialogs and callbacks are now executed on the
main thread instead of the UI thread (note that these are the same thread when not using
multi-threaded-message-loop).
The cursor change can now be handled by the client with both windowed and
off-screen rendering.
Returning true from OnCursorChange will disable the default cursor change
behavior. This is functionally equivalent to the
CefBrowserHost::SetMouseCursorChangeDisabled method, so that method has been
removed.
This change adds support for:
- Protocol and request handling.
- Loading and navigation events.
- Display and focus events.
- Mouse/keyboard events.
- Popup browsers.
- Callbacks in the renderer process.
- Misc. functionality required for ceftests.
This change also adds a new CefBrowserProcessHandler::GetCookieableSchemes
callback for configuring global state that will be applied to all
CefCookieManagers by default. This global callback is currently required by the
chrome runtime because the primary ProfileImpl is created via
ChromeBrowserMainParts::PreMainMessageLoopRun (CreatePrimaryProfile) before
OnContextCreated can be called.
ProfileImpl will use the "C:\Users\[user]\AppData\Local\CEF\User Data\Default"
directory by default (on Windows). Cookies may persist in this directory when
running ceftests and may need to be manually deleted if those tests fail.
Remaining work includes:
- Support for client-created request contexts.
- Embedding the browser in a Views hierarchy (cefclient support).
- TryCloseBrowser and DoClose support.
- Most of the CefSettings configuration.
- DevTools protocol and window control (ShowDevTools, ExecuteDevToolsMethod).
- CEF-specific WebUI pages (about, license, webui-hosts).
- Context menu customization (CefContextMenuHandler).
- Auto resize (SetAutoResizeEnabled).
- Zoom settings (SetZoomLevel).
- File dialog runner (RunFileDialog).
- File and JS dialog handlers (CefDialogHandler, CefJSDialogHandler).
- Extension loading (LoadExtension, etc).
- Plugin loading (OnBeforePluginLoad).
- Widevine loading (CefRegisterWidevineCdm).
- PDF and print preview does not display.
- Crash reporting is untested.
- Mac: Web content loads but does not display.

A CORS preflight request is an "OPTIONS" request sent to a server prior to a
cross-origin XMLHttpRequest or Fetch request. The server's response determines
which HTTP request methods are allowed and supported, and whether credentials
such as Cookies and HTTP Authentication should be sent with requests.
A CORS preflight request will only be sent if certain conditions are met. For
example, it will be sent for requests that have potentially unsafe HTTP
methods [1] or request headers [2]. See the NeedsPreflight function in
services/network/cors/cors_url_loader.cc for full details.
CORS preflight functionality is implemented in the network service and will not
be triggered if the client handles the request instead of allowing it to proceed
over the network. Since the preflight request itself also runs in the network
service it cannot be intercepted by the client.

The request.trusted_params.isolation_info.site_for_cookies value must
match request.site_for_cookies.
This change also adds unit test coverage for cross-origin GET redirects.
This fixes an IsCanonical() DCHECK failure triggered by calling
CanonicalCookie::Create for a non-cookieable URL.
This change also adds unit test coverage for cross-origin cookie
behavior with sub-resource requests (iframe, XHR, Fetch).
- CefURLRequest::Create is no longer supported in the renderer process
(see https://crbug.com/891872). Use CefFrame::CreateURLRequest instead.
- Mac platform definitions have been changed from `MACOSX` to `MAC`
(see https://crbug.com/1105907) and related CMake macro names have
been updated. The old `OS_MACOSX` define is still set in code and CMake
for backwards compatibility.
- Linux ARM build is currently broken (see https://crbug.com/1123214).
To reduce text execution time and flakyness this change also
introduces a global test server that is initialized when needed
and torn down after all tests have completed.
