This change adds a minimal implementation of the |tabs.update| extension API and
modifies StreamsPrivateAPI::SendExecuteMimeTypeHandlerEvent to return a valid
|streamInfo.tabId| value as required by the navigateInCurrentTab implementation
in chrome/browser/resources/pdf/browser_api.js.
Restore the async CreateBrowser behavior that existed prior to commit 691c9c2
because executing synchronously (for example, from inside OnContextInitialized)
causes issues on MacOS and possibly other platforms.
This change adds support for CEF settings configuration of accept_language_list.
If specified, this value will take precedence over the "intl.accept_languages"
preference which is controlled by chrome://settings/languages.
With the Chrome runtime, Profile initialization may be asynchronous. Code that
waited on CefBrowserContext creation now needs to wait on CefBrowserContext
initialization instead.
The policy->CanAccessDataForOrigin CHECK in NavigationRequest::
GetOriginForURLLoaderFactory was failing because unregistered schemes
(which are already considered non-standard schemes) didn't trigger the
registered non-standard scheme allowance that we previously added in
ChildProcessSecurityPolicyImpl::CanAccessDataForOrigin. This change
modifies GetOriginForURLLoaderFactory to always return an opaque/unique
origin for non-standard schemes resulting in unregistered and non-standard
schemes receiving the same treatment.
New test coverage has been added for this condition, and can be run with:
ceftests --gtest_filter=CorsTest.*CustomUnregistered*
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.
The server thread was not guaranteed to be released in the correct scope on
CEF shutdown. This resulted in occasional thread_restrictions assertions on
ceftests shutdown after running the URLRequestTest suite with the Chrome
runtime enabled.
Chrome currently uses chrome_100_percent.pak, chrome_200_percent.pak,
resources.pak and locales/<locale>.pak files. This change adds CEF
resources to those existing pak files and updates the Alloy runtime to
use them instead of the previous CEF-specific pak files (cef.pak,
cef_100_percent.pak, cef_200_percent.pak, cef_extensions.pak,
devtools_resources.pak) which are no longer generated.
The addition of Chrome resources results in an ~16% (~4.1MB) increase in total
combined pak file size vs. the previous CEF-specific pak files. While a size
increase is not ideal for the Alloy runtime, it seems preferable to the
alternative of distributing separate (and partially duplicated) pak files for
each runtime, which would have added ~9.8MB to the total binary distribution
size.
This fixes an `Unhandled chrome.send("getApps");` error when creating a new tab.
Creating a new tab initially loads chrome://newtab which should then be
rewritten to chrome://new-tab-page for normal profiles in
HandleNewTabURLRewrite. Failure to rewrite the URL results in the loading of
NewTabUI instead of the expected NewTabPageUI. NewTabUI loads different
resources for normal vs incognito/guest profiles (new_tab.js vs
incognito_tab.js), and new_tab.js calls chrome.send("getApps") via
page_list_view.js. This then fails in WebUIImpl::ProcessWebUIMessage because
the message is unhandled.
The Chrome browser can now be hosted in a Views-based application on Mac
(see issue #2969).
To launch a fully-featured Chrome window using cefsimple:
$ open cefsimple.app --args --enable-chrome-runtime
To launch a minimally-styled Views-hosted window using cefsimple:
$ open cefsimple.app --args --use-views [--enable-chrome-runtime]
To launch a fully-styled Views-hosted window using cefclient:
$ open cefclient.app --args --use-views [--enable-chrome-runtime]
Known issues:
- Some Views unit tests are currently failing on Mac.
The Chrome browser can now be hosted in a Views-based application on Windows
and Linux.
To launch a fully-featured Chrome window using cefsimple:
$ cefsimple --enable-chrome-runtime
To launch a minimally-styled Views-hosted window using cefsimple:
$ cefsimple --enable-chrome-runtime --use-views
To launch a fully-styled Views-hosted window using cefclient:
$ cefclient --enable-chrome-runtime --use-views
Views unit tests also now pass with the Chrome runtime enabled:
$ ceftests --gtest_filter=Views* --enable-chrome-runtime
Known issues:
- Popup browsers cannot be intercepted and reparented.
To avoid conflicting IDs between Alloy (which uses cef.pak) and Chrome
(which uses chrome_100_percent.pak) the cef/LICENSE.txt file is now included
in both cef/libcef/resources/cef_resources.grd and
chrome/app/theme/chrome_unscaled_resources.grd with different ID values.
The cef.pak file currently contains both CEF-specific resources and Chrome
resources that are already included in the default *.pak files distributed
with Chrome. In the future we should remove this duplication and just
distribute the same *.pak files as Chrome for the majority of resources.
- Only install network intercepts for Profiles that have an associated
CefBrowserContext. For incognito windows the CefBrowserContext is
associated with the OffTheRecordProfileImpl's original Profile.
- cefsimple: Return the default CefClient instance for browser windows
created via the Chrome UI, and allow Chrome to show error pages.
