We must use the serial for generating the uuid.
We use the serial for the port_id and jack_port_uuid_generate() can
be used to turn that into a uuid. So all mappings to and from
uuid need to be with serials.
That tries to both set the buffersize and the samplerate of the graph.
Document them in README.md
Also add the same env variables to pw-stream and pw-filter.
The port struct's `id` member has been renamed to `port_id`,
but the `pw_log_trace_fp()` invocation sites weren't changed.
Fixes: 029539831d ("jack: rework port allocation")
Port ids should be allocated using a map.
Only keep a port_id for the ports we allocate ourselves.
Keep just one port free list, there is no reason to keep per direction
free lists.
Get the port from the object directly.
See #1714
Now that object ids are not reused we can simplify some things. We
don't need to keep a map around with our own unique ids.
Keep all objects in one per client list, mark the removed ones as
removed, allow lookups of the removed objects, recycle half of the
oldest removed objects when there are too many of them.
Remember what we last returned from jack_get_buffer_size and only
emit a buffersize change event when somwthing new is configured.
Fixes startup of jconvolver.
Fixes#1989
pipewire-jack/src/meson.build:
Add the custom `jack_implementation=pipewire` pkgconfig variable to the
generated jack.pc file to be able to distinguish jack implementations.
As jack implementations exist with jack1, jack2 and pipewire-jack, it is
not (easily) possible to distinguish them by looking at the version
alone (particularly the case with jack2 vs. pipewire-jack, as they share
the same headers).
Related to #1666
Make the alignment parameter optional when negotiating buffers.
Default to a 16 bytes alignment and adjust for the max cpu
alignment.
Remove the useless align buffer parameter in plugins, we always
set it to 16 anyway.
After we get a reposition request, bring the state to the SYNC state
again so that clients can align with the new position.
Fixes a problem with reposition when using the jack transport.
Fixes#1907
As per JACK API description the call to jack_deactivate should
disconnect all ports because an inactive client can't have connections.
This disconnect is missing in the current API and results in left-over
links after the call and malfunction to clients (e.g. Music Player
Daemon).
To fix it this commit goes through the list of links to owned ports and
disconnect them.

When a client produces output on a port and there is a link between the
output port and an input port of the client, make sure that the new
data appears on the input port.
We do this by keeping track of what links are between our ports and when
we get the peer id of a port input, we can related this to our port
again. Some mixer inputs will then fetch content from our own ports and
so we can prepare the output for them. This can be converting midi to
control messages or moving the output buffer id to the io area so that
the input mixer can pick up the new buffer.
Fixes#1839
Always pause processing until the main loop has processed the buffer
change callback. This makes it less likely for clients in the same
process to use a new buffersize before the other client has received
the callback.
In carla, one client is receiving the buffer size callback and the other
clients are expexted to be paused until the callback for the client is
completed.
Move some warnings when a wakeup was missed to info messages. The
warning can repeat a lot and is otherwise quite useless and already
reported elsewhere.
Don't do the default latency calculation, it might interfere with
the client latency values. Instead just use the client values and
fold multiples of quantum in the quantum latency field.
0 is a valid min latency so we can't use it as an unset value. Use
some large value instead and when nothing was configured, assume it
is 0.
Fixes#1839
Keep per type free_lists so that we can't reuse an old port object for
a link/node. This makes it more likely that ports are still available
after being freed.
Keep all allocated objects indexed in a global cache map. Use the global
cache index as the jack_port_id_t in connection and port registration
callbacks. Since the port_id is unique per allocated object and since
the objects types are never changed, we can always find a port with the
given port_id in the cache.
This vastly improves tools like catia that insist on querying objects
after they have been removed/destroyed.
Sort ports per node and then per node-specific port_id. This will
keep related ports together and will sort them based on when they
were created.
Fixes#1780
Add a jack.show-monitor option (default true) that makes it possible
to hide the monitor ports.
Monitor ports are not enabled by default on JACK and maybe they also
should not for PipeWire. Or maybe we need some tweaks for some apps.
See #1760
Dequeue a new buffer only once and reuse this queued buffer when
jack_port_get_buffer() is called multiple times in process().
Recycle an old buffer in the next cycle.
After calling process, mark all input buffers as consumed, process the
empty buffers and move the output buffers to the mix ports.
Fixes#1748
