This fixes duplicate symbol errors when building CEF sample applications as
part of the Chromium build. These applications pick up a link-time dependency
on base.lib via the //sandbox and/or //testing/gtest targets which then
conflict with the symbols provided by the libcef_dll_wrapper target.
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.
If a WeakPtr references an already-destroyed object, operator-> and
operator* end up simply dereferencing nullptr. However, dereferencing
nullptr is undefined behavior and can be optimized in surprising ways
by compilers. To prevent this from happening, add a defence of last
resort and CHECK that the WeakPtr is still valid.
Based on https://crrev.com/bbb64b5c69
- CefURLRequest::Create is no longer supported in the renderer process
(see https://crbug.com/891872). Use CefFrame::CreateURLRequest instead.
- Mac platform definitions have been changed from `MACOSX` to `MAC`
(see https://crbug.com/1105907) and related CMake macro names have
been updated. The old `OS_MACOSX` define is still set in code and CMake
for backwards compatibility.
- Linux ARM build is currently broken (see https://crbug.com/1123214).
- Windows: 10.0.19041 SDK is now required.
- macOS: 10.15.1 SDK (at least Xcode 11.2) is now required.
- Remove CefMediaSource::IsValid and CefMediaSink::IsValid which would
always return true.
- Add new CefSettings.external_message_pump option and
CefBrowserProcessHandler::OnScheduleMessagePumpWork() callback.
- Improve documentation related to CefDoMessageLoopWork().
- Pass `--external-message-pump` command-line flag to cefclient or
cef_unittests to test the new mode.
- 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).
