This reverts commit 0e4c16e120.
This is part of the reversion of BlueZ 5 support so it can be added back
in a separate set of modules. This makes the code easier to maintain and
decrease PulseAudio's binary size.
Since the hashmap stores a pointer to the key provided at pa_hashmap_put()
time, it make sense to allow the hashmap to be given ownership of the key and
have it free it at pa_hashmap_remove/free time.
To do this cleanly, we now provide the key and value free functions at hashmap
creation time with a pa_hashmap_new_full. With this, we do away with the free
function that was provided at remove/free time for freeing the value.
This patch removes all occurrences of double and triple
newlines.
Command used for this:
find . -type d \( -name ffmpeg \) -prune -o \
-regex '\(.*\.[hc]\|.*\.cc\)' \
-a -not -name 'adrian-aec.*' -a -not \
-name reserve.c -a -not -name 'rtkit.*' \
-exec sed -i -e '/^$/{N;s/^\n$//}' {} \;
Two passes were needed to remove triple newlines.
The excluded files are mirrored files from external sources.
This patch replaces every occurrence of ')\n{' with ') {'.

With BlueZ 5, if the remote device suspends the audio, the transport
state will change to "idle" and the endpoint is not required to release
the transport, since this could introduce race conditions. Therefore,
ignore the call to pa_bluetooth_transport_release() if the transport is
not acquired any more.
The new D-Bus API doesn't support access rights, which weren't used by
PulseAudio anyway, but it does solve a race condition: now optional
acquires can be implemented by bluetooth-util atomically using the D-Bus
TryAcquire() method.
BlueZ 5 exposes a 'State' property in the media transport interface.
With regard to PA, this replaces the profile-specific interfaces, since
they were being used to know if the audio was streaming or not.
Add the code to parse the properties of the media transport object when
a PropertiesChanged signal is received.
Note that the transport might have an owner other than BlueZ, and thus
the property changes would be emitted from arbitrary senders. For
performance reasons, the installed match considers the interface name
where the property has changed.
It could be possible to install and remove the D-Bus matches dynamically
when a new owner is registered/unregistered, but filtering based on the
interface name seems good enough already.
Install matches for signals ObjectManager.InterfacesAdded and
ObjectManager.InterfacesRemoved, and process the devices that are
registered and unregistered dynamically.
Parse the result of ObjectManager.GetManagedObjects(), which includes
all objects registered, their interfaces and the corresponding
properties per interface.
The 'Name' property of the Device interface became optional in BlueZ 5
and may not be present anymore (that happens when testing against the
PTS 4.7.0), so it's better not to expose it to clients so they don't
rely on its existence.
Port creation is now slightly different. It is now similar to how
other objects are created (e.g. sinks/sources/cards).
This should become more useful in the future when we move more stuff to
the ports.
Functionally nothing has changed.
This commit makes the code cleaner, avoiding unnecessary line breaks. It
also changes the debug message elements order, to make it look more
natural ("path, interface, member" instead of "interface, path,
member").
If we find a microphone output port, it is probably something else
than a microphone. Therefore label it "Bluetooth output" instead of
"Microphone".
Same goes for Headphones and Speakers, but in the other direction.

If BlueZ crashes exactly while PulseAudio waits for the GetProperties reply, the
device has already been removed from the hashmap and therefore an assertion
failure is experienced.
The solution consists of ignoring the reply in these cases.
The problem can be observed in the following traces:
D: [pulseaudio] bluetooth-util.c: Bluetooth daemon appeared.

The card profile availability flag already provides all the necessary
information and therefore all Bluetooth ports can be merged, leaving
the two generic ones only: "bluetooth-input" and "bluetooth-output". The
availability of these port now represents whether the device is
streaming audio, with the following mapping:
- PA_AVAILABLE_UNKNOWN: some profile connected but not streaming
- PA_AVAILABLE_NO: no profiles connected
- PA_AVAILABLE_YES: some profile streaming (regardless of which)
Each port's flag represents the profiles with the corresponding I/O
capabilities (pa_direction_t).
Use the card profile availability flag instead of port availability in
order to automatically switch profiles, for example when a paired phone
starts streaming A2DP audio.
Use the transport's state to not only update the ports availability, but
also to update the card profile availability flag. The interpretation is
as follows:
- PA_AVAILABLE_UNKNOWN: BT profile is connected but no audio streaming
- PA_AVAILABLE_NO: BT profile disconnected
- PA_AVAILABLE_YES: BT profile connected and audio streaming
Generalize the availability flag in order to be used beyond the scope of
ports.
However, pa_port_availability_t is left unchanged to avoid modifying the
protocol and the client API. This should be replaced by pa_available_t
after a validation phase of this new generic enum type.
thread_mq.outq may contain some unprocessed messages, which should be
dispatched before unreffing the sink and source. If the sink and
source are unreffed before all messages to them have been dispatched,
the unreffing won't free the sink and source, and that in turn will
likely cause problems with things getting freed in a wrong order.
A transport should be considered connected only after the connection
procedure is complete, as expressed in audio_state_to_transport_state().
module-bluetooth-device should be loaded only after at least one
transport is not only created (during configuration), but also
connected.
This fixes the issue of premature acquire attempts sometimes experienced
when a headset is connected (issue not present in v3.0 though).
The previous patch removed module-gconf's dependency on the userdata
pointer of the free callback, and that was the only place where the
userdata pointer of pa_free2_cb_t was used, so now there's no need for
pa_free2_cb_t in pa_hashmap_free(). Using pa_free_cb_t instead allows
removing a significant amount of repetitive code.
While reading from the SCO socket, there is no guarantee regarding the
resulting packet size. In some rare cases, it might not even match the
alignment expected in pa_source_post(), resulting in an assertion
failure inside pa_volume_memchunk():
I: [alsa-sink] module-loopback.c: Could not peek into queue
I: [alsa-sink] module-loopback.c: Could not peek into queue
I: [alsa-sink] module-loopback.c: Could not peek into queue
E: [bluetooth] sample-util.c: Assertion 'pa_frame_aligned(c->length, spec)' failed at pulsecore/sample-util.c:725, function pa_volume_memchunk(). Aborting.
Program received signal SIGABRT, Aborted.

Make sure the reply to SetConfiguration() is sent before the internal
hook is fired. This is important because the hook could have side
effects including D-Bus interfactions (i.e. transport Acquire() being
called during module startup).
