rdar://171032272
Reviewed by Per Arne Vollan.
Add a new WebKit preference UseUIProcessForBackForwardItemLoading to gate the
UIProcess-driven
back/forward navigation feature for child frames.
- Add UseUIProcessForBackForwardItemLoading to UnifiedWebPreferences.yaml (type
bool, status
unstable, default false for all layers)
- Expose _useUIProcessForBackForwardItemLoading /
_setUseUIProcessForBackForwardItemLoading:
on WKPreferences via WKPreferencesPrivate.h and WKPreferences.mm
This flag will be used to guard all new code paths introduced in subsequent
patches.
No new tests. No behavioral changes.
