When loading a module, remap the pulseaudio properties to pipewire ones
for consistency.
move the media-roles to remap, because it's more about remapping between
pa and pw.
Fixes#2076
Most feature checks already use #ifdef, and do not care about
the value of the macro. Convert all feature checks to do that,
and simplify the meson build scripts by replacing
if cond
cdata.set('X', 1)
endif
with
cdata.set('X', cond)
When the pulse server context is being freed, only a single reference
should be alive to each sample because the pending samples
are all destroyed beforehand.
Clean everything up when the context is destroyed to avoid
problems stemming from the destruction order of objects
in the context.
Furthermore, free messages after all clients have been freed
because `client_free()` may very well call `message_free()`
which would lead to memory leaks if `impl->free_messages` were
processed first.
A stream's lifetime is tied to that of the client, it cannot outlive
the client object. Streams also do not increase the client's reference
count. It is not possible for a stream to exist after the corresponding
client has been destroyed.
Hence it is not necessary to manage the client's reference count
or lifetime in `do_destroy_stream()`. All works related to a particular
stream are cancelled in `stream_free()`, which is called
before the client is destroyed.
When the `done` flag was first added in
9f9be7d7f2, it was
actually needed because cleanup was implemented
using a per-client eventfd which was signalled when
something related to the particular client needed
to be freed. The function that ran, then, checked
each stream's `done` flag, and freed them as necessary.
However, since c70a5de526,
the stream cleanup is done using a work queue, and as
a consequence, the `done` flag is no longer needed.
When the `disconnecting` flag was first added in
d44fdabea1, a client's
streams were not explicitly destroyed when it was freed,
instead, only the client's pw_core was disconnected,
which then caused all related streams to be destroyed.
Thus there needed to be a way to determine why the stream's
state changed to PW_STREAM_STATE_UNCONNECTED as it may have
been because the client is disconnecting or because the
stream has been "killed" in some other way.
The `COMMAND_{PLAYBACK,RECORD}_STREAM_KILLED` command
only needed to be sent to the client in the second case.
However, at the moment, all streams of a client are explicitly
destroyed before it's pw_core is disconnected. This makes the
`disconnecting` flag unnecessary, thus it can be removed.
Move the reference counting from `pending_sample_free()`
into `on_sample_done()` so that the client's references
are managed in a single place.
The reason why `pending_sample_free()` cannot simply call
`client_unref()` is that `client_free()` may be called from
`manager_disconnect()` regardless of the reference count,
and, in turn, `pending_sample_free()` may be called,
which could then lead to a recursive call to `client_free()`.
We should always advance the read pointer when we are underrun and
not corked. This will request more bytes from the client to make
things advance.
Fixes#2041
Use the lower 32 bits of the object serial as the index. When there is
an overflow, use an invalid index, which will probably result in a
protocol error.
Don't use max_quantum as the upper quantum limit, this is now scaled
with the rate. Use quantum_limit instead. We don't really care about the
max_quantum anymore so get rid of the field.
