with ISOLATE_ENV, it isolates the global environment between scripts
just like it did before; without it, it uses a common environment
with MINIMAL_STD, it restricts even further the available library
functions; useful for configuration files that don't need to do
actual scripting, just to define some tables
The component loader is a more generic and extensible mechanism
of loading components; modules are one type of component...
The idea is to make scripts and config files also be components,
loaded by plugins that inherit WpComponentLoader
* use the activate/deactivate system from WpObject,
which allows async activation and error reporting
* drop 'module' property, use 'core' from WpObject
* Use a more complete API to introspect SPA types
* Avoid the need for the Tables enumeration; the tables
are now registered with a string
* Avoid the need for initialization, work directly on spa_types
and other static data
* Allow working with Object pods that are not Params;
the PARAMS table was previously hardcoded in the pod implementation
* Add a different dynamic type registration system, closer to
how spa type works. The only regression is that we can no longer
register additional custom object fields (custom SPA_PROP_* for example),
but this feature can be re-added later
This patch allows configuring an "extension" string that filters
files not only by extension, but also by a subdirectory of the
standard configuration path(s).
The "extension" can now have the following format:
"subdirectory/path/extension"
which is split on the last '/' and looks for files that end with
".extension" in "WIREPLUMBER_CONFIG_DIR/subdirectory/path/"
If no subdirectory is specified, the code behaves just like it did
before.
Now the WpPipewireObject interface is directly implemented by the mixin
and there is another interface that users of the mixin must implement
in order for the mixin to work proprely.
A lot of manual stuff that proxy classes had to do before are now
in the mixin. Also most of the data that would normally reside in Private
structures is now in the mixin data structure (stored as qdata on the object).
This is achieving the best amount of code reuse so far.
For impl objects (WpImpl*) there are also default implementations of the
standard pipewire object methods and the INFO & PARAM_* features are
more coherently enabled during the whole lifetime of these objects.
This is to mark private functions that are exposed in public headers.
These functions will not be exported from the library and will
generate a warning when client code is trying to use them.
