This functionality stopped being relevant after the removal of Flash support
in January 2021. The last remaining PPAPI plugin (PDF viewer) will switch to
a non-plugin implementation (PdfUnseasoned) in M100.
Use chrome://inspect for remote debugging. The localhost server landing
page is currently deprecated and will be removed in M100 (see
https://crbug.com/1232509#c25).
- Remove CefRequestContextHandler::OnBeforePluginLoad and
CefRequestContext::PurgePluginListCache (fixes issue #3047). These methods
stopped being relevant after the removal of Flash support in January 2021.
The last remaining PPAPI plugin (PDF viewer) will switch to a non-plugin
implementation in the near future (see https://crbug.com/702993#c58) and
functionality related to plugin filtering has already been removed in
https://crrev.com/343ae351c9.
This CL removes the following deprecated APIs:
- base::Bind()
- base::Callback
- base::Closure
- base::CancelableCallback
- base::CancelableClosure
The behavior that these APIs provided is still available using the *Repeating*
variants. However, consider strongly whether using these variants is actually
necessary in your case or whether the *Once* variants will suffice: unless your
callback *objects* (note: not variables!) need to be called multiple times,
they most likely can and should be the Once variants.
This applies the same changes as https://crrev.com/6cc94b5339.
This removes CefSettings.ignore_certificate_errors and
CefBrowserSettings.ignore_certificate_errors. Due to NetworkService
requirements these values must now be configured globally via the
"ignore-certificate-errors" command-line flag.
This removes CefBrowserSettings.universal_access_from_file_urls and
CefBrowserSettings.file_access_from_file_urls. Due to NetworkService
requirements these values must now be configured globally via command-line
flags ("allow-universal-access-from-files" and "allow-file-access-from-files"
respectively).
Also remove the kAllowFileAccessFromFileUrls switch in CEF which duplicates
the existing kAllowFileAccessFromFiles switch in Chromium (see issue #1785).
AppCache is deprecated in favor of Service Workers and support will be
fully removed soon (~M95). See https://web.dev/appcache-removal/.
Also add missing "allow-file-access-from-files" command-line switch for
CefBrowserSettings.file_access_from_file_urls.
When BackForwardCache is enabled and the user navigates the main frame
back/forward a new RFH may be created for an existing main frame GlobalId value
and CefFrameHostImpl (e.g. an object that was previously Detach()ed after main
frame navigation called SetMainFrame, but for which RenderFrameDeleted was not
subsequently called due to insertion in the BackForwardCache). In this case we
can re-attach the new RFH to the existing main frame CefFrameHostImpl in
RenderFrameHostStateChanged and resume processing of messages.
Swapping back/forward to an existing (already loaded) renderer does not trigger
new notifications for draggable regions (e.g. RenderFrameObserver::
DraggableRegionsChanged is not called by default). We therefore explicitly
request an update of draggable regions by sending the DidStopLoading message to
the renderer.
A new |reattached| parameter is added to CefFrameHandler::OnFrameAttached to
support identification of BackForwardCache usage by the client.
To test with unit tests:
Run `ceftests --gtest_filter=DraggableRegionsTest.DraggableRegionsCrossOrigin
--enable-features=BackForwardCache`
To test manually:
1. Run `cefclient --enable-features=BackForwardCache --use-views
--url=http://tests/draggable`, note that draggable regions work.
2. Load https://www.google.com via the address bar, note that draggable regions
are removed.
3. Go back to http://tests/draggable, note that draggable regions work.
4. Go forward to https://www.google.com, note that draggable regions are
removed.
To test:
Run `cefclient.exe --use-views --hide-frame --hide-controls`
Add `--enable-chrome-runtime` for the same behavior using the Chrome location
bar instead of a text field.
Widevine CDM binaries will be downloaded on supported platforms shortly after
application startup. Widevine support will then become available within a few
seconds after successful installation on Windows or after the next application
restart on other platforms. The CDM files will be downloaded to a "WidevineCdm"
directory inside the `CefSettings.user_data_path` directory.
Pass the `--disable-component-update` command-line flag to disable Widevine
download and installation. Pass the `--component-updater=fast-update` command-
line flag to force Widevine download immediately after application startup.
See the related issue for additional usage details.
- 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.
ClientAppRenderer::Delegate callbacks are executed for all tests. In this case
CorsTest.IframeAllowScriptsCustomNonStandardSchemeToServer was crashing on Linux
because CefBrowser::GetMainFrame() returns nullptr in the renderer process when
called from a cross-origin sub-frame.
See the new cef_frame_handler.h for complete usage documentation.
This change includes the following related enhancements:
- The newly added CefBrowser::IsValid method will return false (in the browser
process) after CefLifeSpanHandler::OnBeforeClose is called.
- CefBrowser::GetMainFrame will return a valid object (in the browser process)
until after CefLifeSpanHandler::OnBeforeClose is called.
- The main frame object will change during cross-origin navigation or
re-navigation after renderer process termination. During that time,
GetMainFrame will return the new/pending frame (in the browser process) and
any messages that arrive for the new/pending frame will be correctly
attributed in OnProcessMessageReceived.
- Commands to be executed in the renderer process that may fail during early
frame initialization (ExecuteJavaScript, LoadRequest, etc.) will now be
queued until after the JavaScript context for the frame has been created.
- Logging has been added for any commands that are dropped because they arrived
after frame detachment.
A reference to a received CefProcessMessage object and/or associated argument
list can now be kept outside of the OnProcessMessageReceived callback. The
argument list is no longer explicitly owned by the CefProcessMessage object
and can be individually assigned to other CefValue types as needed (e.g. by
passing to SetList, etc). Depending on client usage this could reduce the
potential for unnecessary copies of the list contents.
Received messages can also be sent back using SendProcessMessage (after which
the CefProcessMessage would become invalid as discussed in issue #3123). This
is not new behavior but we have now added explicit unit test coverage for it.
This also no longer requires a copy of the argument list contents.
Note that a received argument list is initially read-only for logical
consistency. Assignment to another CefValue object could potentially remove
the read-only status because it is not an intrinsic property of the underlying
Chromium data type. This is fine because, at that point, ownership has been
transfered to the new CefValue object and the original logical context (as
part of the CefProcessMessage) no longer applies.
