Add support for MimeHandlerViewInCrossProcessFrame (fixes issue #2727) The PDF loading documentation in extension_system.cc has be updated to describe the new code paths. To support delivery of input events to the mime handler renderer process it is now necessary to route events via the correct RWHV interface. For Aura-based platforms (Windows/Linux) this means RWHVAura::On*Event and for macOS this means RWHVMac::RouteOrProcess*Event. Since Aura uses UI event types these have become the source of truth on Aura-based platforms with conversion to Web event types when needed (primarily for OSR). This change also adds a timeout for CefProcessHostMsg_GetNewBrowserInfo to avoid a hung renderer process if the guest WebContents route is not registered via CefMimeHandlerViewGuestDelegate::OnGuestDetached as expected prior to CefBrowserInfoManager::OnGetNewBrowserInfo being called. This timeout can be disabled for testing purposes by passing the `--disable-new-browser-info-timeout` command-line flag. The `--disable-features=MimeHandlerViewInCrossProcessFrame` command-line flag can be used for a limited time to restore the previous implementation based on BrowserPlugin. That implementation will be deleted starting with the 3897 branch update. Known issues: - ExecuteJavaScript calls on the frame hosting the PDF extension will not be routed to the mime handler renderer process. - The PDF extension will not load successfully if blocked by ChromePluginPlaceholder and then manually continued via the "Run this plugin" context menu option (see https://crbug.com/533069#c41).

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.

Implement NetworkService request interception/handling (see issue #2622). Implementation notes: - Chromium change: CookieMonster::SetCookieableSchemes needs to be called immediately after the CookieMonster is created in NetworkContext:: ApplyContextParamsToBuilder. Add a Profile::GetCookieableSchemes method and NetworkContextParams.cookieable_schemes member (set from ProfileNetworkContextService::CreateNetworkContextParams) to support that. - Chromium change: Add a ContentBrowserClient::HandleExternalProtocol variant that exposes additional NetworkService request information. - GetResourceResponseFilter is not yet implemented. API changes: - Resource-related callbacks have been moved from CefRequestHandler to a new CefResourceRequestHandler interface which is returned via the GetResourceRequestHandler method. If the CefRequestHandler declines to handle a resource it can optionally be handled by the CefRequestContextHandler, if any, associated with the loading context. - The OnProtocolExecution callback has been moved from CefRequestHandler to CefResourceRequestHandler and will be called if a custom scheme request is unhandled. - Cookie send/save permission callbacks have been moved from CefRequestHandler and CefResourceHandler to CefResourceRequestHandler. - New methods added to CefResourceHandler that better match NetworkService execution sequence expectations. The old methods are now deprecated. - New methods added to CefRequest and CefResponse. Known behavior changes with the NetworkService implementation: - Modifying the |new_url| parameter in OnResourceRedirect will no longer result in the method being called an additional time (likely a bug in the old implementation). - Modifying the request URL in OnResourceResponse would previously cause a redirect. This behavior is now deprecated because the NetworkService does not support this functionality when using default network loaders. Temporary support has been added in combination with CefResourceHandler usage only. - Other changes to the request object in OnResourceResponse will now cause the request to be restarted. This means that OnBeforeResourceLoad, etc, will be called an additional time with the new request information. - CefResponse::GetMimeType will now be empty for non-200 responses. - Requests using custom schemes can now be handled via CefResourceRequestHandler with the same callback behavior as builtin schemes. - Redirects of custom scheme requests will now be followed as expected. - Default handling of builtin schemes can now be disabled by setting |disable_default_handling| to true in GetResourceRequestHandler. - Unhandled requests (custom scheme or builtin scheme with default handling disabled) will fail with an CefResponse::GetError value of ERR_UNKNOWN_URL_SCHEME. - The CefSchemeHandlerFactory::Create callback will now include cookie headers. To test: - Run `cefclient --enable-network-service`. All resources should load successfully (this tests the transparent proxy capability). - All tests pass with NetworkService disabled. - The following tests pass with NetworkService enabled: - CookieTest.* - FrameTest.* (excluding .*Nav) - NavigationTest.* (excluding .Redirect*) - RequestHandlerTest.* - RequestContextTest.Basic* - RequestContextTest.Popup* - RequestTest.* - ResourceManagerTest.* - ResourceRequestHandlerTest.* (excluding .Filter*) - SchemeHandlerTest.* - StreamResourceHandlerTest.*

For Aura-based platforms (Windows/Linux) this means RWHVAura::On*Event and for macOS this means RWHVMac::RouteOrProcess*Event. Since Aura uses UI event types these have become the source of truth on Aura-based platforms with conversion to Web event types when needed (primarily for OSR). This change also adds a timeout for CefProcessHostMsg_GetNewBrowserInfo to avoid a hung renderer process if the guest WebContents route is not registered via CefMimeHandlerViewGuestDelegate::OnGuestDetached as expected prior to CefBrowserInfoManager::OnGetNewBrowserInfo being called. This timeout can be disabled for testing purposes by passing the `--disable-new-browser-info-timeout` command-line flag. The `--disable-features=MimeHandlerViewInCrossProcessFrame` command-line flag can be used for a limited time to restore the previous implementation based on BrowserPlugin. That implementation will be deleted starting with the 3897 branch update. Known issues: - ExecuteJavaScript calls on the frame hosting the PDF extension will not be routed to the mime handler renderer process. - The PDF extension will not load successfully if blocked by ChromePluginPlaceholder and then manually continued via the "Run this plugin" context menu option (see https://crbug.com/533069#c41).

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.*
