Pass a new |popup_id| parameter to OnBeforePopup and call a new
OnBeforePopupAborted callback if the popup is aborted before
OnAfterCreated is called for the popup browser. Add new
CefBrowserHost::GetBrowserByIdentifier and GetOpenerIdentifier
methods to assist with retrieval of associated browsers.
In cefclient, clean up state when a popup is aborted and close
any associated popup browsers when the opener browser is closed.
This also works when running with `--use-default-popup`.
Also enables logging by default for Release builds (previously
required the `--enable-logging` flag). Logging can still be
disabled by passing the `--disable-logging` flag.
Set enable_alloy_bootstrap=false to build with Alloy bootstrap code
removed. Extension API is documented as deprecated in comments but
not compiled out with this arg.
Split the Alloy runtime into bootstrap and style components. Support
creation of Alloy style browsers and windows with the Chrome runtime.
Chrome runtime (`--enable-chrome-runtime`) + Alloy style
(`--use-alloy-style`) supports Views (`--use-views`), native parent
(`--use-native`) and windowless rendering
(`--off-screen-rendering-enabled`).
Print preview is supported in all cases except with windowless rendering
on all platforms and native parent on MacOS. It is disabled by default
with Alloy style for legacy compatibility. Where supported it can be
enabled or disabled globally using `--[enable|disable]-print-preview` or
configured on a per-RequestContext basis using the
`printing.print_preview_disabled` preference. It also behaves as
expected when triggered via the PDF viewer print button.
Chrome runtime + Alloy style behavior differs from Alloy runtime in the
following significant ways:
- Supports Chrome error pages by default.
- DevTools popups are Chrome style only (cannot be windowless).
- The Alloy extension API will not supported.
Chrome runtime + Alloy style passes all expected Alloy ceftests except
the following:
- `DisplayTest.AutoResize` (Alloy extension API not supported)
- `DownloadTest.*` (Download API not yet supported)
- `ExtensionTest.*` (Alloy extension API not supported)
This change also adds Chrome runtime support for
CefContextMenuHandler::RunContextMenu (see #3293).
This change also explicitly blocks (and doesn't retry) FrameAttached
requests from PDF viewer and print preview excluded frames (see #3664).
Known issues specific to Chrome runtime + Alloy style:
- DevTools popup with windowless rendering doesn't load successfully.
Use windowed rendering or remote debugging as a workaround.
- Chrome style Window with Alloy style BrowserView (`--use-alloy-style
--use-chrome-style-window`) does not show Chrome theme changes.
To test:
- Run `ceftests --enable-chrome-runtime --use-alloy-style
[--use-chrome-style-window] [--use-views|--use-native]
--gtest_filter=...`
- Run `cefclient --enable-chrome-runtime --use-alloy-style
[--use-chrome-style-window]
[--use-views|--use-native|--off-screen-rendering-enabled]`
- Run `cefsimple --enable-chrome-runtime --use-alloy-style [--use-views]`
Frame identifiers have changed from int64_t to string type. This is due
to https://crbug.com/1502660 which removes access to frame routing IDs
in the renderer process. New cross-process frame identifiers are 160-bit
values (32-bit child process ID + 128-bit local frame token) and most
easily represented as strings. All other frame-related expectations and
behaviors remain the same.
With PdfUnseasoned the PDF file will be loaded in a dedicated renderer process.
We identify this process by adding the kPdfRenderer command-line flag (similar
to how kExtensionProcess is used to identify an extension renderer process). We
then avoid calling GetNewBrowserInfo for the PDF renderer process because we
know the request will otherwise time out.
This change introduces a few minor CEF API behavior changes:
- A CefProcessMessage object cannot be reused after being passed to
SendProcessMessage.
- The |extra_info| argument to CefRenderProcessHandler::OnBrowserCreated may
now be NULL.
Where appropriate, we now utilize the default UTF string encoding format and
shared memory to reduce copies and conversions for the cross-process
transfer of arbitrary-length strings. For example, CefFrame::GetSource/GetText
now involves zero UTF conversions and zero copies in the browser process for
the CefString delivered to CefStringVisitor::Visit().
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.
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 `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.
