Add support for direct DevTools protocol messaging (fixes issue #2961). This change allows the client to directly send and receive DevTools protocol messages (send method calls, and receive method results and events) without requiring a DevTools front-end or remote-debugging session. This change includes additional supporting changes: - Add a new CefRequestHandler::OnDocumentAvailableInMainFrame callback (see issue #1454). - Add a CefParseJSON variant that accepts a UTF8-encoded buffer. - Add a `--devtools-protocol-log-file=<path>` command-line flag for logging protocol messages sent to/from the DevTools front-end while it is displayed. This is useful for understanding existing DevTools protocol usage. - Add a new "libcef_static_unittests" executable target to support light-weight unit tests of libcef_static internals (e.g. without requiring exposure via the CEF API). Files to be unittested are placed in the new "libcef_static_unittested" source_set which is then included by both the existing libcef_static library and the new unittests executable target. - Linux: Remove use_bundled_fontconfig=false, which is no longer required and causes unittest build errors (see issue #2424). This change also adds a cefclient demo for configuring offline mode using the DevTools protocol (fixes issue #245). This is controlled by the "Offline mode" context menu option and the `--offline` command-line switch which will launch cefclient in offline mode. When cefclient is offline all network requests will fail with ERR_INTERNET_DISCONNECTED and navigator.onLine will return false when called from JavaScript in any frame. This mode is per-browser so newly created browser windows will have the default mode. Note that configuring offline mode in this way will not update the Network tab UI ("Throtting" option) in a displayed DevTools front-end instance.

Add support for direct DevTools protocol messaging (fixes issue #2961). This change allows the client to directly send and receive DevTools protocol messages (send method calls, and receive method results and events) without requiring a DevTools front-end or remote-debugging session. This change includes additional supporting changes: - Add a new CefRequestHandler::OnDocumentAvailableInMainFrame callback (see issue #1454). - Add a CefParseJSON variant that accepts a UTF8-encoded buffer. - Add a `--devtools-protocol-log-file=<path>` command-line flag for logging protocol messages sent to/from the DevTools front-end while it is displayed. This is useful for understanding existing DevTools protocol usage. - Add a new "libcef_static_unittests" executable target to support light-weight unit tests of libcef_static internals (e.g. without requiring exposure via the CEF API). Files to be unittested are placed in the new "libcef_static_unittested" source_set which is then included by both the existing libcef_static library and the new unittests executable target. - Linux: Remove use_bundled_fontconfig=false, which is no longer required and causes unittest build errors (see issue #2424). This change also adds a cefclient demo for configuring offline mode using the DevTools protocol (fixes issue #245). This is controlled by the "Offline mode" context menu option and the `--offline` command-line switch which will launch cefclient in offline mode. When cefclient is offline all network requests will fail with ERR_INTERNET_DISCONNECTED and navigator.onLine will return false when called from JavaScript in any frame. This mode is per-browser so newly created browser windows will have the default mode. Note that configuring offline mode in this way will not update the Network tab UI ("Throtting" option) in a displayed DevTools front-end instance.

Add chrome runtime support for more callbacks and ceftests (see issue #2969) 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. The following ceftests are now passing when run with the "--enable-chrome-runtime" command-line flag: CorsTest.* DisplayTest.*:-DisplayTest.AutoResize DOMTest.* DraggableRegionsTest.* ImageTest.* MessageRouterTest.* NavigationTest.* ParserTest.* RequestContextTest.*Global* RequestTest.* ResourceManagerTest.* ResourceRequestHandlerTest.* ResponseTest.* SchemeHandlerTest.* ServerTest.* StreamResourceHandlerTest.* StreamTest.* StringTest.* TaskTest.* TestServerTest.* ThreadTest.* URLRequestTest.*Global* V8Test.*:-V8Test.OnUncaughtExceptionDevTools ValuesTest.* WaitableEventTest.* XmlReaderTest.* ZipReaderTest.*

chrome: win/linux: Add support for browser with native parent (see issue #3294) 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.

Implement Views framework on Windows and Linux (issue #1749). - Add Views header files in a new include/views directory. - Add initial top-level window (CefWindow), control (CefBrowserView, CefLabelButton, CefMenuButton, CefPanel, CefScrollView, CefTextfield) and layout (CefBoxLayout, CefFlowLayout) support. See libcef/browser/views/view_impl.h comments for implementation details. - Add Views example usage in cefclient and cefsimple and Views unit tests in cef_unittests. Pass the `--use-views` command-line flag to cefclient, cefsimple and cef_unittests to run using the Views framework instead of platform APIs. For cefclient and cefsimple this will create the browser window and all related functionality using the Views framework. For cef_unittests this will run all tests (except OSR tests) in a Views-based browser window. Views- specific unit tests (`--gtest_filter=Views*`) will be run even if the the `--use-views` flag is not specified. - Pass the `--hide-frame` command-line flag to cefclient to demo a frameless Views-based browser window. - Pass the `--hide-controls` command-line flag to cefclient to demo a browser window without top controls. This also works in non-Views mode. - Pass the `--enable-high-dpi-support` command-line flag to cef_unittests on Windows to test high-DPI support on a display that supports it. - Add CefImage for reading/writing image file formats. - Add CefBrowser::DownloadImage() for downloading image URLs as a CefImage representation. This is primarily for loading favicons. - Add CefMenuModel::CreateMenuModel() and CefMenuModelDelegate for creating custom menus. This is primarily for use with CefMenuButton. - Add CefBrowser::TryCloseBrowser() helper for closing a browser. Also improve related documentation in cef_life_span_handler.h. - Rename cef_page_range_t to cef_range_t. It is now also used by CefTextfield. - Remove CefLifeSpanHandler::RunModal() which is never called. - Add draggable regions example to cefclient.

Enable strict site isolation by default (see issue #2498) This restores the default site isolation mode for Chromium on desktop platforms. Unit tests have been updated to reflect the new behavior expectations. Known behavior changes in CEF are as follows: - A spare renderer process may be created on initial browser creation or cross- origin navigation. This spare process may be used with a future cross-origin navigation or discarded on application shutdown. As a result CefRenderProcessHandler::OnRenderThreadCreated, which is called shortly after renderer process creation, can no longer be used to reliably transfer state for the currently in-progress navigation. Unit tests have been updated to use the CreateBrowser/OnBeforePopup |extra_info| value for transferring test state to CefRenderProcessHandler::OnBrowserCreated which will be called in the correct/expected renderer process. - Cross-origin navigations will again receive a new renderer process, as expected. This behavior had briefly regressed in M78 due to the ProcessSharingWithDefaultSiteInstances feature becoming enabled by default. - Cross-origin navigations initiated by calling LoadURL in the renderer process will now crash that process with "bad IPC message" reason INVALID_INITIATOR_ORIGIN (213). This is a security feature implemented in Chromium. - A DevTools browser created using CefBrowserHost::ShowDevTools will receive the same CefRenderProcessHandler::OnBrowserCreated |extra_info| value that was set via CreateBrowser/OnBeforePopup for the parent browser.

This is useful for understanding existing DevTools protocol usage. - Add a new "libcef_static_unittests" executable target to support light-weight unit tests of libcef_static internals (e.g. without requiring exposure via the CEF API). Files to be unittested are placed in the new "libcef_static_unittested" source_set which is then included by both the existing libcef_static library and the new unittests executable target. - Linux: Remove use_bundled_fontconfig=false, which is no longer required and causes unittest build errors (see issue #2424). This change also adds a cefclient demo for configuring offline mode using the DevTools protocol (fixes issue #245). This is controlled by the "Offline mode" context menu option and the `--offline` command-line switch which will launch cefclient in offline mode. When cefclient is offline all network requests will fail with ERR_INTERNET_DISCONNECTED and navigator.onLine will return false when called from JavaScript in any frame. This mode is per-browser so newly created browser windows will have the default mode. Note that configuring offline mode in this way will not update the Network tab UI ("Throtting" option) in a displayed DevTools front-end instance.
