Add shell script to sample PulseAudio memory usage while increasing
the number of connected 'paplay' clients over time.
Linux kernel /proc/$PID/smaps Private and Shared_Dirty fields are used
to accurately measure the total size of used dirty pages over time.
This shall be useful for benchmarking the PA daemon's memory while
introducing new features like per-client SHM access and memfds.
Also add an empty benchmarks-collection directory 'benchmarks/'. All
output from the benchmarking tools shall be saved in this place, with
timestamps and symbolic links to the newest versions.

The gnome/unity-control-center UIs have a master volume slider, and
three sub-sliders: balance, fade, and subwoofer. Balance and fade
use PA's set_balance and set_fade APIs accordingly, but the subwoofer
slider sometimes does unintuitive things.
In order to make that slider behave better, let's add a LFE balance
API that these volume control UIs can use instead. With this API,
the UI can balance between "no subwoofer" and "only subwoofer" with
"equal balance" in the middle, which would make it more consistent
with the behaviour of the other sliders.

We currently only support one and two channels for volumes, and
bail out otherwise. This makes Xonar users unhappy because they
have a volume with eight channels, and bailing out means they
don't have a path/port at all.
This way they will at least have a port, which will in turn make
the gnome/unity UI behave better.

Seccomp-BPF uses SIGSYS signal to trigger
the trap handler attached to sys_open.
If the signal is blocked then the kernel kills
the process whenever pulse audio calls 'open'.
The result backtrace is terminating in sys_open.
That's why it is required to keep SIGSYS unblocked
if it is currently unblocked and trapped.
This patch allows to have pulse audio working
in the Chromium sandbox.

In case a tarball-version file is present, use that and quit.
Otherwise git will continue looking for directories, potentially
finding .git directories which are dirty and mark the version as such.

We need to guard the pstream with an extra ref to ensure
it is not destroyed at the time we check whether or not the
srbchannel is destroyed.

In case the same jack causes one port to become available and another
one unavailable, the available should be reported first.
This is to avoid unnecessary changes: e g, consider a 'Headphone Jack'
making 'Headphone' available and 'Speaker' unavailable. In case the
unavailable change triggers first, and there is also a currently available
third port (e g 'Digital out'), the routing system might choose to route
to this port because neither of the 'Speaker' and 'Headphone' ports are
available.

With the exception of when trying to clean up shm files,

If bashcompletiondir was empty, the check didn't catch that. As
a result, the symlinks that were supposed to be generated in the
completion directory were created in the root directory.
I'm not sure how much they are needed nowadays with the latest
changes to the subset elimination (I found this while
researching a bug on an older PA version), but I guess they could
be added for consistency at least.

Commit 262bdae0330e used symbols which are only available if systemd
support was compiled in. Fix by using the appropriate #ifdef guards.
Also document the resulting PULSE_LOG_JOURNAL environment variable
behavior if systemd journal support was not compiled in.
[Diwic: changed wording slightly.]

By introducing such an environment variable, applications using the
PA client libraries can configure these libraries to send their logs
directly to the journal.
While client libraries journal logging can be indirectly achieved
using PULSE_LOG_SYSLOG, this pollutes the journal. Meta data gets
replicated twice: once in the journal meta fields and once in the
syslog(3) plain-text message itself.
For attaching any backtraces, also introduce the PA-specific journal
meta field PULSE_BACKTRACE. This is the recommend journal practice
instead of appending any furuther data to the logging message itself.

The nodelete flag indicates that we don't want our libraries to be
unloaded. It's only relevant on libraries, so let's not use it for
executables. Trying to use it on executables breaks things on some
platforms.

Pulseaudio fails to build on the Alpha architecture due to a failure
in the volume-test of the test suite. I had reported this to the
Debian bug tracker [1] but the maintainer has asked that I forward the
patch to this mail list. The failure in volume-test occurs because it
is compiled with -ffast-math which implies -ffinite-math-only of which
the gcc manual states that it optimizes for floating-point arithmetic
with the assumption that arguments and results are not NaNs or
+/-infinity, and futher notes that it may result in incorrect output.
On the Alpha platform that is somewhat an understatement as the use of
non-finite floating-point arithmetic with -ffinite-math-only results in
a floating-point exception and the termination of the program.
The volume-test converts volumes into decibels (so a zero volume
becomes a negative infinity) and proceeds to add two volumes (in
decibels), thus does arithmetic with non-finite floating point numbers
despite being compiled with -ffast-math!
I attach a patch that protects against the arithmetic with non-finite
numbers for your consideration. With that patch the test-suite passes
on Alpha.
Cheers
Michael.

It is possible that we get a zero-length memchunk to work with.
Specifically, this happens the resampler (which is called before the
lfe-filter) consumes all the input data, but does not (yet) produce any
output data.
Reproduced using:
pulseaudio --resample-method=soxr-mq
pactl load-module module-null-sink sink_name=lfe_test channels=3 channel_map=front-left,front-right,lfe
paplay --raw /dev/zero --rate=48000 -d lfe_test
Thanks to the original reporter for the backtrace:

Originally pointed out by Georg Chini.
Calculating buffer = buffer + (send_counter - recv_counter)
in one branch and buffer = 2 * buffer - (recv_counter - send_counter)
looks very obviously wrong. In other words, before the patch, the
contribution from the previous lines was double-counted.
Libraries from modlibexec_LTLIBRARIES list require
not only libpulsecommon but also libpulse and
libpulsecore from lib_LTLIBRARIES list.
This patch fix race in 'make -j X install' (with X is 2 and more)
when building/installing inside chroot placed on RAM-disk(tmpfs).

Based on some googling, strtod_l() is defined in xlocale.h on BSD.
Glibc seems to define it in stdlib.h, but only if GNU extensions are
enabled (otherwise the function won't be available). So, this patch
should fix the use of strtod_l() on BSDs, but on other systems things
may or may not be still broken.
The original patch author is Jakob Fink <jfink@gmx.at>. He sent this
patch to the freebsd-gnome mailing list:

We have no strtof_l calls in the code, so it doesn't make sense to
check that function's availability. We have one strtod_l call, so
let's check that instead.
I don't know if this change makes any practical difference. I just
wondered why we had HAVE_STRTOF_L ifdefs in core-util.c for code that
didn't use strtof_l.
