An shm ringbuffer that is used for low overhead server-client communication.
Signalling is done through eventfd semaphores - it's based on pa_fdsem to avoid
syscalls if nothing is waiting on the other side.

As the automake documentation says:
AM_CPPFLAGS: The contents of this variable are passed to every compilation
that invokes the C preprocessor; it is a list of arguments to the preprocessor.
For instance, -I and -D options should be listed here
AM_CFLAGS: This is the variable the Makefile.am author can use to pass in
additional C compiler flags.

Not having ORC_SOURCE defined results in different tarballs depending on
whether the dev issuing 'make dist' has orc support enabled or disabled.
Specifying ORC_SOURCE unconditionally addresses that, without causing
negative effects on users not having orc in the end.
pulsecore/core-format.c was recently added to libpulsecommon, and
core-format.c depends on functions in libpulse, which libpulsecommon
doesn't link to. That broke building with --as-needed. This patch adds
pulse/format.c to libpulsecommon, so that core-format.c doesn't need
to depend on libpulse any more. format.c pulls in also the dependency
to json-c.

I will need to use the function from outside libpulse.
I added the channel map argument, because the function will be called
from another function that is expected to initialize the channel map.
I don't know if it's in practice necessary, but it shouldn't do any
harm either.
The journal is a component of systemd, that captures Syslog messages,
Kernel log messages, initial RAM disk and early boot messages as well
as messages written to STDOUT/STDERR of all services, indexes them and
makes this available to the user.
It can be used in parallel, or in place of a traditional syslog daemon,
such as rsyslog or syslog-ng.
The journal offers a couple of improvements over traditional logging
facilities (e.g. advanced filtering capabilities).
This patch adds support for logging directly to the journal using its
native API.
Create a wrapper module called module-bluetooth-discover to avoid
breaking backward-compatibility of default.pa. This wrapper may
eventually be dropped altoghether with BlueZ 4 support.
pa_bluetooth_discovery is the struct that holds information about known
Bluetooth audio devices and other information about the Bluetooth stack.
This commit also creates bluez5-util.[ch], which will hold a lot of
utility functions to help with the BlueZ 5 support.
module-bluetooth-proximity has not worked for quite a while, since it
uses pre-BlueZ4 APIs. Nobody complained since then, which is a good
indication that it doesn't have much users. Even the original commit
message refers to it more as a toy than as something of great use: "add
new fun module that automatically mutes your audio devices when you
leave with your bluetooth phone, and unmutes when you come back"
Removing it we completely remove the dependency on libbluetooth.
A recent feature addition added a dependency on X11, but this
dependency was not specified in Makefile.am, leading to linker
errors.

The old tunnel module duplicates functionality that is in libpulse,
due to implementing the native protocol, and the protocol code in
the old tunnel module tends to get broken every now and then, because
people forget to update the tunnel module protocol implementation
when changing the native protocol. module-tunnel-source-new avoids this
problem by using libpulse to communicate with the remote server.

If there is a "Line Out" jack present, then add this path. The fallback
analog-output will be a subset of this path and removed.
I only use the "Line Out Jack" or "Line Out Front Jack" for actual jack
detection - without anything connected to the front jack, it makes little
sense to enable the port.
(Another option could perhaps be to use different paths for stereo line out
and surround line outs, but that could be a possible future improvement.)
This test is intended to measure real latency by playing a sample to a
sink and capturing that over a loopback interface. The loopback can
either be physical (cable running from headphone out to line in) or
virtual (monitor source or module loopback).
Also included in this is calibration code to make sure that volumes are
sufficiently adjusted to be able to detect the played back signal (and
that there aren't false positives due to line noise).
One of the objectives of all this is to later factor out the setup code
to allow us to easily write more loopback tests for various
functionality (volumes, resampling, mixing, etc.).
The mixer paths are not available in ${builddir} - we need to look in
${srcdir}. This should fix running an in-tree build without make install
as well as alsa-mixer-path-test in make distcheck.
Since the most straightforward way to define PA_SRCDIR was in
Makefile.am, I'm moving PA_BUILDDIR there as well for consistency.

It checks all files in the mixer/paths directory and checks
- that the file can be parsed without errors
- that the file is actually shipped in the makefile

ipacl-test fails if there is no SSH server running on your machine.
Since it is not a PulseAudio error not to have an SSH server running,
this test should not be run as part of the "make check" test suite.

The previous volume handling could cause ear damage: by default the
ladspa sink volume was 100%, and with flat volumes that would cause
the master sink volume to jump to 100% too.
idea is to allow optimized code path (similar to volume code)
and rework/specialize mixing cases to enable runtime performance improvements

pa_silence_memory() pulls sample-util as a dependency, so it had to
be moved from libpulsecore to libpulsecommon. sample-util in turn
pulls some more stuff.
This module works pretty similar to the module-role-cork.
It should be used as an alternative to that module. Basically
it decreases the volume of the streams specified in ducking_roles
in the presence of at least one stream specified in trigger_roles.
Also, it's possible to choice the volume that will be used in the
ducking streams and if it should operates in all devices or not.

This reverts commit 1569601864.
Rethinking this, it makes more sense to not add this to the check
framework. This is mostly useful for exposing ALSA driver issues, and
it's handy to be able to build this as a standalone executable.
Currently, Windows versions of pacat and friends fail because the current
poll emulation is not sufficient (it only works for socket fds).
Luckily Gnulib has a much better emulation that seems to work good enough.
The implementation has been largely copied (except a few bug fix
regarding timeout handling, to be pushed upstream) and works on pipes
and files as well. The copy has been obtained through their gnulib-tool utility,
which gives a LGPLv2.1+ licensed file.
This fixes the "Assertion (!e->dead) failed" error coming and lets pacat
and friends stream happily to/from a server (I didn't actually test parec).
final:
* includes some minor style fixes and build-time changes to allow
building a single binary for neon and non-neon systems
v4:
* fix for sample length < 4
v3:
* convert from intrinsics to inline assembly
v2:
* load and store data with vld1/vld1q and vst1/vst1q, resp., to work
around alignment issues of compiler-generated vldmia instruction
* remove redundant check for NEON flags

Commit dd31d652a ("utils: Adding a function to get volume from string")
uses pa_sw_volume_from_dB(), which is part of libpulse, in libpulsecore.
This breaks as-needed builds. We fix this by also building the volume
code in libpulsecommon.
