4fbd247231
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.*

// Implementation of the cef::BrowserDelegate interface. Lifespan is controlled
|
|
// by the Browser object. Only accessed on the UI thread.
|
|
//
|
|
// The Browser object represents the top-level Chrome browser window. One or
|
|
// more tabs (WebContents) are then owned by the Browser object via
|
|
// TabStripModel. A new Browser object can be created programmatically using
|
|
// "new Browser" or Browser::Create, or as a result of user action such as
|
|
// dragging a tab out of an existing window. New or existing tabs can also be
|
|
// added to an already existing Browser object.
|
|
//
|
|
// The Browser object acts as the WebContentsDelegate for all attached tabs. CEF
|
|
// integration requires WebContentsDelegate callbacks and notification of tab
|
|
// attach/detach. To support this integration a cef::BrowserDelegate
|
|
// (ChromeBrowserDelegate) member is created in the Browser constructor and
|
|
// receives delegation for the Browser callbacks. ChromeBrowserDelegate creates
|
|
// a new ChromeBrowserHostImpl when a tab is added to a Browser for the first
|
|
// time, and that ChromeBrowserHostImpl continues to exist until the tab's
|
|
// WebContents is destroyed. The associated WebContents object does not change,
|
|
// but the Browser object will change when the tab is dragged between windows.
