Change the default stack size to 8 MiB for 64-bit and 0.5 MiB for 32-bit.
CEF's main thread needs at least a 1.5 MiB stack size in order to avoid
stack overflow crashes. However, if this is set in the PE file then other
threads get this size as well, leading to address-space exhaustion in 32-bit
CEF. A new CefRunWinMainWithPreferredStackSize function uses fibers to switch
the main thread to a 4 MiB stack (roughly the same effective size as the
64-bit build's 8 MiB stack) before running any other code.
This change additionally moves the existing Windows-only functions
CefSetOSModalLoop and CefEnableHighDPISupport from cef_app.h to cef_win.h.
Fix "error: use of result of assignment to object of volatile-
qualified type 'volatile gsize' (aka 'volatile unsigned long') is
deprecated [-Werror,-Wdeprecated-volatile]" when building with
use_sysroot=false on Ubuntu 18.04.
On Windows these new CefDisplay methods convert between screen pixel coordinates
and screen DIP coordinates. On macOS and Linux these methods just return a copy
of the input coordinates.
This configuration applies to Official Release builds only.
Chromium currently provides PGO profiles for Windows x86/x64, MacOS x64/ARM64
and Linux x64. Official builds for these platforms must run automate-git.py with
the `--with-pgo-profiles` command-line flag. Official builds for other platforms
must disable PGO builds by adding `chrome_pgo_phase=0` to GN_DEFINES.
The make_distrib script will now generate Doxygen docs by default
if the doxygen command-line tool is installed. Run with `--no-docs`
(`--no-distrib-docs` with automate-git.py) to disable docs generation.
This fixes official build linker errors like:
lld-link: error: Output data is larger than 4 GiB. File size 4,341,682,176 too large for current PDB page size 4096
lld-link: error: failed to write PDB file ./libcef.dll.pdb

This service is required by the "PermissionOnDeviceNotificationPredictions"
feature which is enabled by default in https://crbug.com/1350956. It uses a
Google backend service as described at https://go.dev/solutions/google/chrome.
This change removes the usage of PredictionBasedPermissionUiSelector, which
triggered this dependency, along with related startup complexity that was added
to support the optimization/prediction service in the M106 update.
Send a FrameDetached message from CefFrameHostImpl::Detach before closing
the RenderFrame connection to avoid an immediate reconnect attempt by the
renderer.
When BFCache is disabled the intentionally detached frame will never be
reconnected. When BFCache is enabled the intentionally detached frame will
be reconnected via CefFrameImpl::OnWasShown if/when it exits the cache.
Run with "--vmodule=frame_*=1 --enable-logging=stderr --no-sandbox" on the
command-line to see these log messages from both the browser and renderer
processes.
