When a global is removed, also remove the proxies. We can have multiple
proxies to a global otherwise when a client has a sequence of events
queued from the server like this:
Global 1 added
Global 1 removed
Global 1 added
The proxy we added in the firt event would not be destroyed because the
server did not know about it when global 1 was removed and then a
second one would be made.
Reorganize the latency setup in one place, return a desired device
latency for use as quantum.
PulseAudio assigns half of the (tlength - minreq) latency to the sink
but we can't do that because our sinks have a max-quantum of latency.
Fix this by clamping our calculated sink latency to the quantum
PulseAudio subtracts the sink latency from the tlength in adjust latency
mode, so we need to do the same.
This makes PULSE_LATENCY_MSEC values bahave more like pulseaudio.
See #1769
Keep track of the proxies and remove them when the global is removed.
Otherwise we might end up in a case where the have 2 proxies when
an add/remove/add sequence of messages was queued.
When an object is created, it is marked creating until all roundtrips
complete. If the object is removed in between, we don't remove it
because find_object does not return creating objects.
Make find_object also return the creating objects to fix this.
The current compile-time-check only tests for the getrandom() syscall
wrapper of libc. The presence of this wrapper however does not relate to
the presence of the actual syscall at runtime.
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
You are supposed to allocate with _insert_new()/_remove() or use
someone elses allocated number with _insert_at(), never mix the
two or it will give an error.
Sami Farin pointed out on #833 that on Linux kernels older than 5.6,
/dev/random blocks when entropy estimates are too low, whereas
/dev/urandom does not.

Let video-src unconditionally call _trigger_process() when it is
ready. This will either start the graph when it is the driver or emit
a RequestProcess event to the driver.
Let video-play-pull intercept the RequestProcess command and use it
to do a trigger_process(). Otherwise use a timer to pull in the next
frame.
This commit uses the video-src-alloc and video-play-reneg templates to create
examples for manual fixation at the format negotiation phase. These
clients simulate modifier negotiation done by clients handling DmaBufs.
Note: Neither client is capable of proper DmaBuf handling!
video-play-fixate can be used to test if a producer is capable to
fallback to shm buffer transport, while video-src-fixate can only be
used with the former example!
Send unfixed Format to nodes but don't proceed to the next state.
When EnumFormat is emited, change the link state back to INIT to restart
the negotiation.

Commit 42d8b2b1 "Remove legacy FreeBSD compatibility code" removed
compatibility with old versions of FreeBSD, but also removed
compatibility with old versions of Linux and glibc, which was requested
in #833.
This partially reverts commit 42d8b2b167.
Resolves: #833

In Meson, string.contains() is a substring check but array.contains() is
a full string check. Let's use 'foo in bar' style instead to avoid
confusion.
Supported since meson 0.49.0
count the number of changes and then when there are any, flip the
SERIAL bit in the param info so that the server can detect a
change. Without this, 2 updated params would not flip the bit and the
param changes would not be noticed.
You are only supposed to use _insert_new()/_remove() or _insert_at()
on the map, If we detect a _insert_at() to a removed item,
return an error because else we might corrupt the free list.
Update unit test accordingly.
Both wireplumber and media-session have a meson variable now that
represents the -uninstalled script, complete with filled-in BUILDDIR
etc.
Let's use those variables for pipewire-uninstalled.conf so we don't have
to fill in the paths here.
