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).
This change moves the SendProcessMessage method from CefBrowser to CefFrame and
adds CefBrowser parameters to OnProcessMessageReceived and
OnDraggableRegionsChanged.
The internal implementation has changed as follows:
- Frame IDs are now a 64-bit combination of the 32-bit render_process_id and
render_routing_id values that uniquely identify a RenderFrameHost (RFH).
- CefFrameHostImpl objects are now managed by CefBrowserInfo with life span tied
to RFH expectations. Specifically, a CefFrameHostImpl object representing a
sub-frame will be created when a RenderFrame is created in the renderer
process and detached when the associated RenderFrame is deleted or the
renderer process in which it runs has died.
- The CefFrameHostImpl object representing the main frame will always be valid
but the underlying RFH (and associated frame ID) may change over time as a
result of cross-origin navigations. Despite these changes calling LoadURL on
the main frame object in the browser process will always navigate as expected.
- Speculative RFHs, which may be created as a result of a cross-origin
navigation and discarded if that navigation is not committed, are now handled
correctly (e.g. ignored in most cases until they're committed).
- It is less likely, but still possible, to receive a CefFrame object with an
invalid frame ID (ID < 0). This can happen in cases where a RFH has not yet
been created for a sub-frame. For example, when OnBeforeBrowse is called
before initiating navigation in a previously nonexisting sub-frame.
To test: All tests pass with NetworkService enabled and disabled.
Requests created using CefURLRequest::Create are not associated with a
browser/frame. When originating from the render process these requests cannot be
intercepted and consequently only http(s) and blob requests are supported. To
work around this limitation a new CefFrame::CreateURLRequest method has been
added that allows the request to be associated with that browser/frame for
interception purposes.
This change also fixes an issue with the NetworkService implementation where
redirected requests could result in two parallel requests being sent to the
target server.
To test: URLRequestTest.* tests pass with NetworkService enabled.
The optional |extra_info| parameter provides an opportunity to specify extra
information specific to the created browser that will be passed to
CefRenderProcessHandler::OnBrowserCreated() in the render process.
- 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.
- The |category| value for all TRACE calls from CEF client applications is now
"cef.client" due to https://crrev.com/331266377d.
- The |with_menu_marker| parameter to CreateMenuButton has been removed due to
https://crrev.com/7f7e382118.
Known issues:
- The CefLoadCRLSetsFile function needs to be re-implemented (see issue #2497).
- Linux: GTK2 support has been removed. The cefclient sample needs to be updated
to use GTK3 (see issue #2014).

- Switch crash reporting from crashpad to breakpad on Windows and OS X.
Adds a new chrome_elf.dll dependency on Windows (issue #1995)
- Remove CefTextfield::GetPlaceholderTextColor() method which is no
longer supported by Chromium.
- Remove |accept_lang| parameter from CefJSDialogHandler::OnJSDialog
and CefFormatUrlForSecurityDisplay (see https://crbug.com/336973#c36).

CEF/Chromium.
- Delete include/cef_runnable.h (issue #1336).
- Build the cef_unittests target using all Chromium headers. Add a
USING_CHROMIUM_INCLUDES define and libcef_dll_wrapper_unittests
target to support this. This change avoids compile errors due to
the divergence of CEF and Chromium base/ header implementations.
The libcef_dll_wrapper sources must now compile successfully with
both CEF and Chromium base/ headers (issue #1632).
- The onbeforeunload message specified via JavaScript is no longer
passed to the client (see http://crbug.com/587940).
- Building on Windows now requires the Windows 10.0.10586 SDK.
- Remove CefParseCSSColor which was implemented using Blink code in the
browser process. This is longer advisable now that the Oilpan GC is enabled.
- Avoid potential renderer process crashes by disabling script actions
on the CefV8Context passed to CefRenderProcessHandler::OnContextReleased.
POST data includes elements that are not represented (issue #1761).
- Add CefRequest::SetReferrer and CefRequest::GetReferrer[URL|Policy]. The
Referer value will no longer be stored in the header map.
- Move request-related conversion logic to CefRequestImpl and standardize the
implementation.
- Introduce native/ and osr/ folders for native (non-platform-agnostic) and
osr (windowless) code respectively.
- Introduce CefBrowserPlatformDelegate for abstracting platform-specific
implementations of browser host functionality.
- Move dialog and menu code to separate manager and platform-specific runner
implementations exposed via CefBrowserPlatformDelegate.

implementations. CefFocusHandler::OnSetFocus() will now also be called for
osr focus changes.
- Support multiple simultaneous popups (issue #1289).
- Improve ordering of CefLoadHandler callbacks. OnLoadingStateChange will
be called before and after all calls to OnLoadStart and OnLoadEnd.
OnLoadStart/OnLoadEnd calls will occur as matching pairs
(see http://crbug.com/539952#c2).
- Remove the |requesting_url| argument to CefGeolocationHandler::
OnCancelGeolocationPermission. Clients can use the |request_id| argument
to track this information themselves.
- Fix a crash when loading the PDF extension in multiple browsers with a
custom CefRequestContext (issue #1757).
- Implement CefRequestHandler::OnBeforeBrowse using NavigationThrottle
instead of ResourceThrottle (see http://crbug.com/537634). The CefRequest
object passed to OnBeforeBrowse will no longer have an associated request
identifier.
- Mac: Remove additional helper apps which are no longer required (see
http://crbug.com/520680)
- Remove the UR_FLAG_REPORT_RAW_HEADERS flag which is no longer supported (see
http://crbug.com/517114)
- Remove the CefBrowserSettings.java parameter. Java is an NPAPI plugin and
NPAPI plugins are no longer supported (see http://crbug.com/470301#c11)

CefRequestContextHandler and add a new policy argument that
supports different actions (allow, block, detect, disable) on a
per-plugin-instance basis.
- Add CefContextMenuHandler::RunContextMenu for providing a custom
context menu implementation.
- Add CefResourceBundleHandler::GetDataResourceForScale for
returning scaled resources (issue #1272).
- Add CefResourceBundle for retrieving resources from the resource
bundle (*.pak) files loaded by CEF during startup or via the
CefResourceBundleHandler.
- Linux: Fix Debug build IO access warning with CefGetMimeType.
- cef_unittests: Move the refcounting implementation from TestHandler
to subclasses in order to support interface inheritance from
subclasses.
- Windows/Mac: Use `--enable-widevine-cdm` command-line flag to
enable download of CDM binaries via the component updater.
- Linux: Use `--widevide-cdm-path` and `--widevine-cdm-version`
command-line flags to load CDM binaries that already exist on
the system.
- A cache-path value is usually required when CDM is enabled.
- Mac: 10.10 SDK is now required for building (see http://crbug.com/463170#c63).
Older SDKs can be used for a short time by setting mac_sdk_min via GYP_DEFINES.
A system-wide installation of the Pepper Flash plugin is available from Adobe
for Windows and Mac OS X platforms as a separate download. To enable automatic
detection and loading of the system-wide installation pass the
`--enable-system-flash` command-line flag.
The Pepper Flash plugin can also be loaded by specifying the file path and
version via the `--ppapi-flash-path=<path> --ppapi-flash-version=<version>`
command-line flags. The version can be identified by viewing the
manifest.json file in the same directory as the Pepper Flash plugin library.
This includes:
- Red underline of misspelled words in html text areas.
- Right-click context menu options to correct the misspelled word.
- New CefBrowser::ReplaceMisspelling method for accepting a word replacement.
- Methods added to CefContextMenuParams for retrieving spelling-related information.
- Uses the unified text checker when auto-correct is not enabled to match Google Chrome behavior.
- On Windows and Linux a hunspell dictionary file will be downloaded to the "<cache_path>/Dictionaries" directory as needed, or used from the <cache_path> directory if the file already exists there. The dictionary file will be downloaded from http://cache.pack.google.com/edgedl/chrome/dict/<LANG>-3-0.bdic where <LANG> is the language abbreviation.
- On OS X the spell checking implementation will use the system NSSpellChecker implementation.
The following command-line flags have been added:
--disable-spell-checking => Disable spell-checking support (no red underline, no dictionary file download, etc).
--enable-spelling-auto-correct => Automatically correct common misspellings while typing (like 'omre' to 'more' on Windows/Linux or 'ehlo' to 'helo' on OS X).
--enable-spelling-service => Enable use of the remote Google spelling service (this requires Google API keys).
--override-spell-check-lang=<LANG> => Use the specified dictionary language <LANG> instead of the language specified in the locales.pak file.

This implementation supports both GPU compositing and software compositing (used when GPU is not supported or when passing `--disable-gpu --disable-gpu-compositing` command-line flags). GPU-accelerated features (WebGL and 3D CSS) that did not work with the previous off-screen rendering implementation do work with this implementation when GPU support is available.
Rendering now operates on a per-frame basis. The frame rate is configurable via CefBrowserSettings.windowless_frame_rate up to a maximum of 60fps (potentially limited by how fast the system can generate new frames). CEF generates a bitmap from the compositor backing and passes it to CefRenderHandler::OnPaint.
The previous CefRenderHandler/CefBrowserHost API for off-screen rendering has been restored mostly as-is with some minor changes:
- CefBrowserHost::Invalidate no longer accepts a CefRect region argument. Instead of invalidating a specific region it now triggers generation of a new frame.
- The |dirtyRects| argument to CefRenderHandler::OnPaint will now always be a single CefRect representing the whole view (frame) size. Previously, invalidated regions were listed separately.
- Linux: CefBrowserHost::SendKeyEvent now expects X11 event information instead of GTK event information. See cefclient for an example of converting GTK events to the necessary format.
- Sizes passed to the CefRenderHandler OnPaint and OnPopupSize methods are now already DPI scaled. Previously, the client had to perform DPI scaling.
- Includes drag&drop implementation from issue #1032.
- Includes unit test fixes from issue #1245.
