This is an attempt to unclutter the API of WpProxy and
split functionality into smaller pieces, making it easier
to work with.
In this new class layout, we have the following classes:
- WpObject: base class for everything; handles activating
| and deactivating "features"
|- WpProxy: base class for anything that wraps a pw_proxy;
| handles events from pw_proxy and nothing more
|- WpGlobalProxy: handles integration with the registry
All the other classes derive from WpGlobalProxy. The reason
for separating WpGlobalProxy from WpProxy, though, is that
classes such as WpImplNode / WpSpaDevice can also derive from
WpProxy now, without interfacing with the registry.
All objects that come with an "info" structure and have properties
and/or params also implement the WpPipewireObject interface. This
provides the API to query properties and get/set params. Essentially,
this is implemented by all classes except WpMetadata (pw_metadata
does not have info)
This interface is implemented on each object separately, using
a private "mixin", which is a set of vfunc implementations and helper
functions (and macros) to facilitate the implementation of this interface.
A notable difference to the old WpProxy is that now features can be
deactivated, so it is possible to enable something and later disable
it again.
This commit disables modules, tests, tools, etc, to avoid growing the
patch more, while ensuring that the project compiles.
A base class for objects that can have optional
features enabled and disabled. The intention is to make
this the superclass of WpProxy.
Instead of following the augment() pattern of WpProxy,
this one follows the more advanced transition pattern
that has been previously implemented in WpSessionItem.
The Dbus device reservation has been moved into a separate module, and has also
been refactored to allow reserving a device name before an actual device is
created. Devices now are created and destroyed by the monitor depending on
whether PipeWire owns the device or not. This also simplifies a lot the device
activation module to always enable devices when they are created, and never
worry about checking whether a device is acquired by PipeWire or not.
meson.build:
When the 'wrap_mode' option is set to 'nodownload' use a system version
of cpptoml. This does not require using git and having a network
connection during build, which is important for Linux packaging
infrastructure.
subprojects/cpptoml.wrap:
Pin revision to last release tag (v0.1.1).
lib/wptoml/*.cpp:
Remove 'include/' prefix from all cpptoml related includes, at is not
required.
Closes#17
* add library.name to not require adding `add-spa-lib` in pipewire.conf
or wireplumber.conf for this to work
* add a commented local=true; it can be useful to run those nodes
locally for testing, sometimes
there are underlying issues with the state management of the graph,
so it's not a very good idea to rely on it to activate / deactivate
our convert node depending on the links that exist
instead, track the links ourselves and create/destroy the corresponding
links to the target node accordingly; it's a more robust approach
it was also not entirely correct that we would previously configure
the convert node to be a driver (node.driver=true); maybe this caused
the underlying issues in the first place... we don't need it now
anyway, so it's gone
