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 we add a cef::BrowserDelegate
(ChromeBrowserDelegate) member that 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.
CEF callback logic is shared between the chrome and alloy runtimes where
possible. This shared logic has been extracted from CefBrowserHostImpl to
create new CefBrowserHostBase and CefBrowserContentsDelegate classes. The
CefBrowserHostImpl class is now only used with the alloy runtime and will be
renamed to AlloyBrowserHostImpl in a future commit.
With site-per-process enabled a spare renderer process will be created
for use with a future browser or navigation. Consequently the
|extra_info| parameter populated in OnRenderProcessThreadCreated will no
longer be delivered to OnRenderThreadCreated in the expected renderer
process. To avoid confusion these callbacks have been removed completely.
After this change CefRenderProcessHandler::OnWebKitInitialized should
be used for startup tasks in the render process, and OnBrowserCreated
should be used in the render process to recieve |extra_info| passed from
CefBrowserHost::CreateBrowser or CefLifeSpanHandler::OnBeforePopup.
- Add new CefSettings.external_message_pump option and
CefBrowserProcessHandler::OnScheduleMessagePumpWork() callback.
- Improve documentation related to CefDoMessageLoopWork().
- Pass `--external-message-pump` command-line flag to cefclient or
cef_unittests to test the new mode.
- Add the ability to pass extra information to child processes using a new CefBrowserProcessHandler::OnRenderProcessThreadCreated callback (issue #744).
- Fix OnBeforeChildProcessLaunch documentation (issue #754).

- Add CefBrowserProcessHandler interface (issue #650).
- Internally re-register supported schemes with CefCookieManager after changing the storage path (issue #651).
- Add CefResourceHandler callbacks for blocking cookie loading and saving (issue #652).
- Allow custom scheme handlers for requests that do not originate from browser content (issue #653).
- Use 'int' instead of 'RequestFlags' for CefRequest::GetFlags and SetFlags (issue #654).
- Rename cef_request.h CreateObject methods to Create (issue #655).
- Add #ifdef guards to cef_tuple.h to allow the use of both cef_runnable.h and base/bind.h in the same unit test source file.
- Retrieve cookieable schemes as part of ClientApp::RegisterCustomSchemes and register with the global cookie manager.
