Do not pass the params of the node in the node_info, instead,
make a method to enumerate the params. This makes it possible for
clients to only enumerate what they need and when they need it.
Improve introspection of a port, add the name and properties.
Add an enum_param method on the port that can be used to enumerate
port formats.
Change -monitor and -cli and add support for enum_params on the node
and port.
Add an audio dsp module that adds an interleaver for each audio sink
and only allows 1 buffer size and format on the ports. The idea is that
dsp (pro-audio) nodes can be inserted in this part of the pipeline.
Expose all ports as globals, linking is then done by specifying
the global id of the ports.
Add method to destroy objects. not much security on this one but
yet but it should allow priviledged clients to kill connections
and other clients etc.
Make events on the global object. Implement the bind with the event,
handle destroy of the globals.
Add link properties
Use append to preserve the order.
Make the protocol client connect call async with a callback when it
completes.
Move the connect methods into separate files, add an empty connect
method that will use the screencast portal to get a pipewire fd.
Use the remote intention to get the connect method.
Add some better error reporting.
Remove the core permission check callback. We can now use the per
client permission configuration.
Rework the flatpak module to use the permissions. When a client
connects, do the portal call and iterate all globals, updating the
permissions. Also update the permissions of newly added globals.
The client is owner of itself.
Don't pass around the client object but keep track of the current
client in the core object. This way we don't need to add a client
argument to functions and can check security when needed.
Pass client to some core functions to make it possible to check
permissions when iterating globals.
Check permissions of factory before using it.
Check permissions in link factory, only allow linking of nodes we can
see.
Check permissions in the autolink module, only try to link to nodes
we can see.
Make client permissions update behave like an atomic update of an
unordered set of permissions, which is perhaps a bit more intuitive.
Make a steal_fd method on the remote.
Add a hello method that sends the initial core info and types to
the client.
With an explicit method we can do this multiple times when we steal
the fd from a remote and use it to make a new remote.
Add properties to global objects to make it easier to select what
nodes and objects to bind too. They can also be used to implement
permissions on the globals based on properties.
Add more error handling in _register.
Make more functions return a result code.
Make a separate pw_module_register, like all other objects.
Make a link factory and use create-object to make links. That way
we can have different kinds of links based on the factory and we
can also hide the factory when link creation should be blocked.
Add a permissions call that can be used to update the permissions
of global objects. This can be used to set specific permissions
on certain objects, hide objects and define the permissions on new
objects. The system is quite generic so that we can extend it later
with more complicated match rules or so.
Remove the per-port memory and only use per-node memory. This will
make it possible to share memory between ports in the future.
Keep refs to memory on the buffers and free (close) the memory
when no longer used.
Do not send the offset and size in the add_mem call, just send the
fd and the flags. The area that we need to map from this to find the
meta, chunk and data are sent in a separate call. This should make
it possible to truncate the memory to a larger size to dynamically
allocate more shared memory for a client.
Remove the Id data type, it's not needed.
Don't automatically map memory in remote.c
Pass the original memory type from server to client.
Handle DmaBuf mem in video-play now that the server passed it on.
Add control objects for all controllable properties on ports.
Try to link compatible control properties in autolink.
Allocate shared memory for the output property memory and configure
the io area on the ports when the controls are linked.
Send the shared memfd to clients when the io area is configured.
Add port_set_io support in remote.c, mmap the control io area and
set on the port.
Add some param helpers
Add volume control to export-source update the volume before
sending each buffer.
Make an int return from pw_node_for_each_port() so that we can return
errors or early exit.
Add pw_port_for_each_param() to iterate params. And use this to collect
the formats.
Reorganize the io parameter ids and objects. Make separate enumerations
for buffer, control, input and output properties.
Add a volume output property to export-source. This is still unused
but will eventually be routed to a PropsIn io area where it can
control the volume of a mixer, for example.
Make a method to find the memory block for the given ptr. We can
use this to find the memfd of the memory if there is any. We can
then remove the Shared metadata on buffers.
