Monitor the device reservation objects and mark the device available.
Don't select nodes from devices that are not available.
Acquire the device reservation when a device starts.
Release the device reservation when we suspend the device again.
Add a asprintf helper function that handles errors correctly.
Use this in places where we use asprintf to avoid warnings when we
don't check the return value.
While we are creating objects on the monitor connection, pause the
policy connection until we have completed a roundtrip and the global
id is bound to the new object.
This way, when we resume the policy connection, we can always find the
newly created and bound object. Without the pause, it's possible that
we receive the new global on the policy connection before we got the
bind reply on the monitor connection and then we would end up with 2
proxies that are not linked together correctly.
Fixes#204
Install the example media-session
Load the media session according to the PATH
Include the example directory in the PATH so we can run the media
session.
Use the DSP media subtype to describe DSP formats. DSP formats
don't include the rate, channels and channel position in the
format and must use the rate and duration from the position io. This
makes it possible to later change the samplerate dynamically without
having to renegotiate the graph.
The same goes for the video DSP format, which uses the io_video_size
from the io_position to get the size/stride. Set this up in the node
based on the defaults from the context.
Make it possible to define defaults in the daemon config file, such
as samplerate, quantum, video size and framerate. This is stored in
the context and used for the DSP formats.
Make it possible to run the session manager without endpoint
modules. Add a simple node policy that links nodes.
Move the session-manager implementation and startup of the
endpoint monitors to a separate module.
Handle async set_param on the device
Never free a proxy without the application doing a pw_proxy_destroy.
It's hard to use when proxies are freed randomly when the server
removes the ids. You have to add destroy notify to all proxies and
deal with the arbirary order in which proxies can be freed.
Instead notify the client of the remove and let it destroy the
proxies itself in the right order. This is in line with how wayland
handles proxies.
A pw_proxy_destroy() will now send a destroy to the server and mark
the proxy as a zombie, waiting for the remove_id confirmation and
then destroy the proxy.
A server remove_id will mark the proxy as removed and emits the
removed event. The app should then pw_proxy_destroy the proxy
to free it.
Leaks all proxies in the session manager because cleanup now needs
to be handled by the app correctly.
This is more in line with wayland and it allows us to create new
interfaces in modules without having to add anything to the type
enum. It also removes some lookups to map type_id to readable
name in debug.
Add method to set and get typed objects from the context. This can
be used to pass around context objects between modules without having
to register them.
Don't pass pw_properties around when we simply need to pass around
config info, only use pw_properties when used to construct an object
that keeps the properties.
