When in permissive mode, the ConfigServer will not treat reads and writes to non-pledged domains as errors, but instead turns them into no-ops: Reads will act as if the key was not found, and writes will do nothing. Permissive mode must be enabled before pledging any domains. This is needed to make GUI Widgets nicer to work with in GML Playground: a few Widgets include reads and writes to LibConfig in order to load system settings (eg, GUI::Calendar) or to save and restore state (eg, GUI::DynamicWidgetContainer). Without this change, editing a layout that includes one of these Widgets will cause GML Playground to crash when they try to access config domains that are not pledged. The solution used previously is to make Playground pledge more domains, but not only does this mean Playground has to know about these cases, but also that working on a layout file can alter the user's settings in other arbitrary apps, which is not something we want. By simply ignoring these config accesses, we avoid those downsides, and Widgets will simply use the fallback values they already have to provide to Config::read_foo_value(). |
