Run each unit test only once. Using CPPUNIT_TEST_SUITE_REGISTRATION
from within the header meant that each unit class was registered again
for each source file that includes the header.
-fixes SIGABRT when mpd is started from a previously paused state
-regression introduced by commit: f5a923b9d1:
'OutputAll: convert to class, move instance to class Partition'
-input_audio_format was previously declared using the static modifier
ensuring it was zero-initialised by default
-the current default-initialised input_audio_format contains garbage at
runtime which allows the AudioFormat.IsDefined() 'fail fast' test in
MultipleOutputs::Update to pass and the SIGABRT follows in
AudioOutput::Open when passed the invalid input_audio_format struct
-switching AudioFormat.IsDefined() for AudioFormat.IsValid() is an
alternative workaround
-fixes regression introduced by:
'8d6fedf8177d0d2ced81e6d93d35c368b2ac69db [PATCH] Mixer: add class MixerListener'
-listener.OnMixerVolumeChanged() called GetVolume() which attempted to acquire
the lock but as per 'pa_threaded_mainloop_lock()' documentation:
This function may not be called inside the event loop thread. Events that are
dispatched from the event loop thread are executed with this lock held
-this patch seperates the underlying action of GetVolume() into a new
GetVolumeInternal() function, to be called only when the lock is already held, as
is the case for the listener.OnMixerVolumeChanged() call
Don't wait for an optimistic write to fail. This is an improved
workaround for the infamous Raspberry Pi bug (see commit af991765).
It works much better and comes without the negative side effects. The
old workaround is now obsolete.
Move code from CreateConfiguredDatabase() and add XDG support. This
implements an automatic Linux fallback for the setting "db_file" if
none was specified.
A SimpleDatabase instance can now "mount" other Database instances at
certain locations. This is used to use a new SimpleDatabase instance
for each storage mount (issued with the "mount" protocol command).
Each such instance has its own database file, stored in the directory
that is specified with the "cache_directory" option.
