With the Chrome runtime, Profile initialization may be asynchronous. Code that
waited on CefBrowserContext creation now needs to wait on CefBrowserContext
initialization instead.
Chromium supports communication with media devices on the local network via
the Cast and DIAL protocols. This takes two primary forms:
1. Messaging, where strings representing state information are passed between
the client and a dedicated receiver app on the media device. The receiver
app communicates directly with an app-specific backend service to retrieve
and possibly control media playback.
2. Tab/desktop mirroring, where the media contents are streamed directly from
the browser to a generic streaming app on the media device and playback is
controlled by the browser.
This change adds support for device discovery and messaging (but not
mirroring) with functionality exposed via the new CefMediaRouter interface.
To test: Navigate to http://tests/media_router in cefclient and follow the
on-screen instructions.
When NetworkService is enabled requests created using CefFrame::CreateURLRequest
will call CefRequestHandler::GetAuthCredentials for the associated browser after
calling CefURLRequestClient::GetAuthCredentials if that call returns false.
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.*
This change removes cookie and request handler functionality that will not
supported by the NetworkService. Specifically, it is no longer possible to
change cookie storage locations at runime by returning a different
CefCookieManager for an already initialized CefRequestContext. After this change
you will need to use a separate CefRequestContext when creating a CefBrowser if
you require separate cookie storage.
The following methods have been removed:
- CefCookieManager::CreateManager
- CefCookieManager::GetBlockingManager
- CefCookieManager::SetStoragePath
- CefRequestContextHandler::GetCookieManager
The following methods have been renamed:
- CefRequestContext::GetDefaultCookieManager to GetCookieManager.
This change substantially simplifies the network implementation in CEF because
it is no longer necessary to proxy objects that are normally owned by Chromium.
Chromium patches that are no longer necessary will be removed as a follow-up
commit.
To test: Verify that `ceftests --gtest_filter=-PluginTest.*` pass with
NetworkService disabled. Plugin tests will be fixed in a follow-up commit.
- Windows: 10.0.17763.0 SDK is now required.
- Mac: 10.13 SDK is now required.
- Removed CefRequestContext::ResolveHostCached which is no longer supported by Chromium.
- Add CefRequestContext::LoadExtension, CefExtension, CefExtensionHandler and
related methods/interfaces.
- Add chrome://extensions-support that lists supported Chrome APIs.
- Add CefBrowserHost::SetAutoResizeEnabled and CefDisplayHandler::OnAutoResize
to support browser resize based on preferred web contents size.
- views: Add support for custom CefMenuButton popups.
- cefclient: Run with `--load-extension=set_page_color` command-line flag for
an extension loading example. Add `--use-views` on Windows and Linux for an
even better example.
- Move all tests from the top-level directory to tests/.
- Move files shared by cefclient and unittests to tests/shared/.
- Add a fused (single header/source file) version of gtest in
tests/gtest/ with associated CMake configuration.
- Test-only headers are now exposed in include/test/. Unit test
targets must define UNIT_TEST in order to access them.
- Replace usage of USING_CEF_SHARED with WRAPPING_CEF_SHARED for
clarity (only the libcef_dll_wrapper target should define it).
- Remove the RENAME_DIRECTORY CMake macro which is no longer used.
- Remove C++11 usage from unittests sources for compatibility with
the binary distribution configuration.
- Windows: Fix build errors due to chrome_elf.dll and imm32.lib
missing from the CMake configuration.
- Preferences are now associated with a CefRequestContext instead of
being stored globally.
- Add methods to CefRequestContext for getting/setting preferences.
- Support single parent inheritance in CEF API classes.
- Support non-virtual inheritance in CEF API classes.
- Support translation of CEF API sub-directories.
- Add test sub-directories for testing-only functionality that will be
available to unit tests but not exposed via the binary distribution.
- Add unit tests for the translator tool.
- Fix parsing of template parameter types that include commas.
- CefRequestContext instances can be configured using a new CefRequestContextSettings structure passed to CefRequestContext::CreateContext.
- Scheme registration is now per-request-context using new CefRequestContext::RegisterSchemeHandlerFactory and ClearSchemeHandlerFactories methods.
- Cookie managers are now per-request-context by default and can be retrieved using a new CefRequestContext::GetDefaultCookieManager method.
- CefURLRequest::Create now accepts an optional CefRequestContext argument for associating a URL request with a context (browser process only).
- The CefRequestContextHandler associated with a CefRequestContext will not be released until all objects related to that context have been destroyed.
- When the cache path is empty an in-memory cache ("incognito mode") will be used for storage and no data will be persisted to disk.
- Add CefSettings.user_data_path which specifies the location where user data such as spell checking dictionary files will be stored on disk.
- Add asynchronous callbacks for all CefCookieManager methods.
- Add PK_LOCAL_APP_DATA and PK_USER_DATA path keys for retrieving user directories via CefGetPath.
- cefclient: Add "New Window" test that creates a new window unrelated to existing windows. When used in combination with `--request-context-per-browser` the new window will be given a new and isolated request context.
