- Convert scoped_ptr to std::unique_ptr from <memory>
- Convert arraysize to base::size from include/base/cef_cxx17_backports.h
- Convert NULL to nullptr
- Include include/base/cef_callback.h instead of include/base/cef_bind.h
- Implicit conversion of CefRefPtr<T> or scoped_refptr<T> to T* is gone;
use .get() instead
See the issue for additional details.
The Chrome runtime requires that cookieable scheme information be available
at Profile initialization time because it also triggers NetworkContext creation
at the same time. To make this possible, and to avoid various race conditions
when setting state, the cookieable scheme configuration has been added as
|cookieable_schemes_list| and |cookieable_schemes_exclude_defaults| in
CefSettings and CefBrowserContextSettings. The CefCookieManager::
SetSupportedSchemes and CefBrowserProcessHandler::GetCookieableSchemes methods
are no longer required and have been removed.
This change also modifies chrome to delay OffTheRecordProfileImpl initialization
so that |ChromeBrowserContext::profile_| can be set before
ChromeContentBrowserClientCef::ConfigureNetworkContextParams calls
CefBrowserContext::FromBrowserContext to retrieve the ChromeBrowserContext
and associated cookieable scheme information. Otherwise, the
ChromeBrowserContext will not be matched and the NetworkContext will not be
configured correctly.
The CookieTest suite now passes with the Chrome runtime enabled.
This fixes an IsCanonical() DCHECK failure triggered by calling
CanonicalCookie::Create for a non-cookieable URL.
This change also adds unit test coverage for cross-origin cookie
behavior with sub-resource requests (iframe, XHR, Fetch).
To reduce text execution time and flakyness this change also
introduces a global test server that is initialized when needed
and torn down after all tests have completed.
This change also restores the Chromium default values for the
SameSiteByDefaultCookies and CookiesWithoutSameSiteMustBeSecure features. See
https://www.chromium.org/updates/same-site for feature details and rollout
timeline.
With this change the CefCookieManager::SetSupportedSchemes method can be used
to disable all loading and saving of cookies for the associated request context.
This matches functionality that was previously available via GetBlockingManager.
This change also fixes a bug where Set-Cookie headers returned for a request
handled via CefSchemeHandlerFactory would be ignored if there was not also a
CefResourceRequestHandler returned for the request.
To test: All CookieTest.* tests pass.
This change fixes a load hang when no custom handlers (CefResourceRequestHandler
or registered scheme handler) are found for a request.
To test: Run `cefsimple --enable-network-service` and all requests load. Test
expectations are unchanged.
This change allows the NetworkService to handle cookie load/save in cases where
cookies will not be filtered (CefResourceRequestHandler::GetCookieAccessFilter
returns null) and the request will be handled by the default network loader.
This represents a minor performance improvement by reducing the volume of cross-
process messaging in the default (no filtering or custom handing) case. Cookie
load/save still needs to be routed through the browser process if a filter is
returned, or if a CefResourceHandler is used for the request.
To test: Test expectations are unchanged.
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.*
The Chromium content layer (which also exposes the NetworkService interface)
generally runs on the UI thread. Previous use of the IO thread for CookieManager
callbacks is an implementation detail of the old network stack that shouldn't be
exposed to clients.
To test: Run ceftests. They should pass as expected.
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.
