As soon as a JACK app is started, the automatic quantum change is
disabled. This means no pulse/alsa app can change the quantum.
The only way to change the quantum is with node.force-quantum or
with the settings metadata.
This means only a JACK buffersize change (usually controlled from the
JACK app, such as in ardour) or a metadata change (from the command
line) can modify things. Both of those are usually caused by a user
action.
For JACK apps where the quantum is allowed to change automatically,
explicit rules need to be placed in the config.
When we get a commit error, try to resync our pointers. This fixes a
problem of endless commit errors after a quantum change because it never
manages to resync properly.
Add an extra private field to the source to store the pollevent of
the current iteration. This changes ABI but it seems an embedded source
is not used outside of our own plugins and the unit test doesn't test
this ABI case.
Whenever a source is removed, we can set the data field of the
pollevent to NULL so that it won't be handled in any iteration anymore.
Avoid dispatching the same event multiple times when doing recursive
iterations.
Add some more unit tests for this.
Fixes#2114
If a node (or metadata) forces a quantum, remove any nodes that
requested a lock-quantum so that we can change the quantum to the new
forced one.
This makes it possible to run jack clients with node.lock-quantum while
still allowing them to change the quantum qith node.force-quantum.
This commit adds a counter for loop_enter/leave and checks:
- consecutive enter are used on the same thread
- leave is used on the same thread as enter
- at destruction, the enter_count must be 0
Call spa_handle_clear() on the handle before freeing.
Actually store the loaded dll in the right array.
First clear the handle, then close the dll.
Fix iteration of the dlls.
Now that sources can't be dispatched anymore after a _remove, we don't
need to keep the destroy_list anymore and we can free the source
immediately.
See #2114
Keep the array of dispatched sources around in the loop. When a source
is removed while dispatching, set the data to NULL so that we don't try
to deref the source again or call its function.
Fixes#2114
Make all tools output to stdout (pw-mon mostly) so that we can pipe the
output around.
Send errors to stderr.
fprintf(stdout, ...) -> printf(...)
setlinebuf for stdout so that pipe works better.
See #2110
Skip spaces before the key. When the previous key ends with a ' or when
there are 2 spaces between keys, the key includes the whitespace
otherwise.
See #2086
For the modules that we load internally, place a pulse.module.id
property on the nodes.
If there is no module.id property on nodes, try to use the
pulse.module.id when introspecting. We should not remap those to
serial numbers.
Fixes#2101
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
Since meson 0.59.0, a feature object has an `allowed()`
method which returns true when the feature is set to
'enabled' or 'auto'.
Utilize that instead of the previously used
not feature.disabled()
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)
For kernels compiled with CONFIG_SND_VERBOSE_PROCFS=n, the pcmXX
/proc/asound entries do not exist. In that case, the "device busy"
check cannot be done, but we should still check existence of PCM devices
correctly.
Count the number of PCM devices from /dev/snd, which should work also
without /proc/asound or /sysfs/class/sound.
Alsa device acp probe results to missing profiles if some PCM devices
are busy. Currently, we retry based on a timeout and give up after some
retries. However, exposing cards with missing profiles is never
useful.
Never expose cards if some PCM devices are busy. Instead, retry adding
device on inotify fd close events, which arrive when some process has
closed a PCM device.
When probing for devices in alsa-udev, check via /proc to avoid inotify
busy loop.
