- 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.
Fixes the following error:
Check failed: !pending_frame_callback_. Got overlapping IssueExternalBeginFrame
To test:
Run `cefclient --off-screen-rendering-enabled --external-begin-frame-enabled`
on Windows without crashing.
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.
The `--disable-request-handling-for-testing` command-line flag would previously
disable handling of all schemes, including custom schemes and internal schemes
such as devtools.
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.
This causes a race related to |notification_state_lock_| assignment when
GetMainFrame is called from multiple threads. GetMainFrame doesn't
trigger any notifications so it shouldn't need that lock. Instead, only
use NotificationStateLock on the UI thread.
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.
BackForwardCache is currently being tested via field trials (see
https://crbug.com/1171298) and can be explicitly disabled using the
`--disable-back-forward-cache` or `--disable-features=BackForwardCache`
command-line flags. The default behavior now matches the Chrome runtime.
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.
