Add return values to events and method callbacks. This makes it
possible to pass any error or async return value.
Add sync/done/error in both directions so that both proxy and resource
and perform/reply sync and produce errors.
Return a SPA_ASYNC from remote method calls (and events), keep the
sequence number in the connection.
With the core sync/done we can remove the client-node done method and
it's internal sequence number along with the seq number in method calls.
We can also use the method/event async return value to perform a sync
with as the unique sequence number for this method.
Add sync method and done/error event to proxy and resource.
Add a port_info event. With this, we get updates to ports pushed to
us, which is more convenient and also allows for better dynamic
add/remove of ports.
We don't need to the PortChanged event anymore
We can remove the get_port_ids/get_n_ports/port_get_info methods.
Update plugins
Make an eventfd for each node and listen for events when the node
is activated.
Reorganize some graphs links to make it possible to activiate nodes
by signaling the eventfd
Pass the peer node to each remote node and let the remote node
directly activate the peer when needed.
Let each node signal the driver node when finished.
With this we don't need to go through the daemon to schedule the
graph, nodes will simply activate eachother. We only go to the
server when there is a server node to schedule.
Keep stats about the state of each node and the time it was
triggered, running and finished.
Improve the allocators to always align the buffer memory to the
requested alignment
Use aligned read and writes for sse functions and check alignment,
optionally falling back to unaligned path.
Add more tests and benchmark cases
Check and warn for misaligned memory in plugins.
Remove the spa_pod_iter helpers
Remove builder/parser vararg recurse option, you have to
manually recurse into structures when needed. This simplifies
things a lot.
Pass spa_pod_frames to builder and parser explicitly, we don't
have to keep an internal stack anymore.
The parser is now almost a mirror image of the builder.
Make the parser safer when iterating over objects, add functions
to check and get pod contents in a safe way.
Make the builder return errno style results on errors
Improve performance of object properties when they are stored and
retrieved in the same order.
Add many more tests for the builder and parser
Add some benchmarks
Automatically parse and build key/value when in objects without having
to prefix the key with ":"
Automatically build control/value when in sequence without the "."
prefix.
Remove the builder with key/pod, taking a reference to the stack built
temporary pods is not allowed in c++. We can use the varargs version
with the same convenient syntax.
Remove the parser "*" option, it is unused.
Improve spa_pod_builder_add_* and spa_pod_parser_get_* and make them
look similar.
Make the monitor and device emit the info and items when the callbacks
are set. This makes it easier to implement the monitor because there
is much less state to keep around and invalidate etc.
Rework the monitors
Add bluez5 device
Set the lowest possible period time, this lowers the latency.
Adjust slaved stream when we are drifting too much.
Use faster snd_pcm_avail and only use get_status when in error.
