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.
The mojo channel used for frame communication may disconnect for a variety of
reasons including frame navigation, frame destruction, or insertion into the
BackForwardCache (when the browser-side frame representation is destroyed and
closes the connection). When disconnect occurs we now evaluate the situation
and reconnect if appropriate.
Connections are now initiated solely from the renderer process and the
RenderFrame is passed as an argument to FrameAttached() instead of being
retrieved independently. Messages are queued while the frame is disconnected
and sent only after FrameAttachedAck() is received from the browser process.
The renderer process will be crashed intentionally with a "connection retry
failure" message if the reconnect fails 3 times in a row.
Add the generated includes/ directory to CEF's "config" so that source files
included in patched Chromium targets (for example, blink_glue.cc) can find
cef_config.h which will be included via `include/internal/cef_types_linux.h`
on Linux.
Fixes a shutdown crash due to `ExtensionsBrowserClient::Set(nullptr)` being
called too early. Some code that may occasionally be triggered via
`content::ContentMainShutdown()` is expecting the extensions objects to still
be valid.
This new ownership pattern matches the code in chrome/.
URLLoaderNetworkServiceObserver is used for routing certificate and
authentication callbacks from the NetworkService to the associated
StoragePartition instance. With request interception enabled this object was
previously only assigned for the initial request. This change adds assignment
for restarted/redirected requests as well.
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.
We need to override ChromeMimeHandlerViewGuestDelegate to handle
OnGuestAttached/Detached callbacks in order to account for the guest renderer
process hosting the PDF extension.
Additional work will be required to account for the renderer process hosting the
PDF viewer when using `--enable-features=PdfUnseasoned` (see issue #2969).
Browser windows created via CefBrowserHost::CreateBrowser should be shown at
creation time. These windows receive default Chromium styling, unlike
CefBrowserView windows which may contain other client-specified Views and
where show state can be configured via CefWindowDelegate::GetInitialShowState
or by calling CefWindow::Show.
- 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.
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.
