With the introduction of prerendering in Chromium it is now possible for
RenderFrameHosts (RFH) to move between FrameTrees. As a consequence we can no
longer rely on FrameTreeNode IDs to uniquely identify a RFH over its lifespan.
We must now switch to using GlobalRenderFrameHostId (child_id, frame_routing_id)
instead for that purpose. Additionally, we simplify existing code by using the
GlobalRenderFrameHostId struct in all places that previously used a
(render_process_id, render_frame_id) pair, since these concepts are equivalent.
See https://crbug.com/1179502#c8 for additional background.
When CefApp::GetRenderProcessHandler returned null
CefRenderFrameObserver::DidCreateScriptContext was returning early (not
calling CefFrameImpl::OnContextCreated) and consequently queued actions
such as JavaScript were never executed.
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.
When building on an ARM64 host the ARM64 configs (arm64) will be generated by
default and the AMD64 configs (x86,x64) will only be generated if the
CEF_ENABLE_AMD64=1 env variable is set.

When BackForwardCache is enabled the old RFH tree may be cached instead of being
immediately deleted as a result of main frame navigation. If a RFH is cached
then delivery of the CefFrameHandler::OnFrameDetached callback will be delayed
until the the RFH is ejected from the cache (possibly not occurring until the
browser is destroyed). This change in OnFrameDetached timing was causing
FrameHandlerTest.OrderSubCrossOrigin* to fail, and the inclusion of cached
frames in CefBrowserInfo::GetAllFrames was causing
FrameTest.NestedIframesDiffOrigin to fail.
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.
Automatically report unit tests to the TeamCity server if run within TeamCity.
See tests/gtest/teamcity/README.cef for details.
To test: Set the TEAMCITY_PROJECT_NAME environment variable and run ceftests.
Fixes the following error:
[FATAL:cef_bind_internal.h(868)] Check failed: receiver->HasAtLeastOneRef().
base::Bind{Once,Repeating}() refuses to create the first reference to ref-counted
objects. That typically happens around PostTask() in their constructor, and such
objects can be destroyed before `new` returns if the task resolves fast enough.
- 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

This change adds a minimal implementation of the |tabs.update| extension API and
modifies StreamsPrivateAPI::SendExecuteMimeTypeHandlerEvent to return a valid
|streamInfo.tabId| value as required by the navigateInCurrentTab implementation
in chrome/browser/resources/pdf/browser_api.js.
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.
Building with dSYMs enabled results in substantially longer link times and
provides minimal benefit for builds that are not intended for distribution.
They can still optionally be enabled by setting enable_dsyms=true via
GN_DEFINES. They remain enabled by default for official builds generated
with is_official_build=true and are required if packaging symbols via the
make_distrib.py script.
The AbortAfterCreated and AbortBeforeBrowse tests were flaking due to a race
between request handling and browser close. The tests would fail if the request
handling completed first.
