This patch removes unsued code from |BluetoothServiceBluedroid|, related
functions, and cleans up the file. It
* removes callbacks,
* removes callback helper tasks,
* removes helper functions, and
* cleans up global variables.
Bluedroid callbacks were usually called on a separate thread that
was specific to this task. So Gecko's Bluetooth Core contained a
number of runnables for executing callback operations on the main
thread.
Since all notifications always run on the main thread, the extra
runnables are not required any longer. This patch integrates them
into the notification methods where possible.
This patch adds the Gecko-side of the Core notifications. The current
implementation of the notification methods has been copied from the
repsective Bluedroid callback methods, with only minor changes to adapt
them to Gecko data types.
A notification is a callback from the Bluetooth backend to inform
Gecko about a event. Bluedroid uses function pointers for this, but
in Gecko we use method calls instead.
Gecko implements notification handlers for the Bluetooth backend. The
backend converts incomming events to Gecko types and forwards them to
the registered notification handler.
This patch adds some runnable classes for running class methods on
the main thread. This is the base of the upcomming notification
mechanism for Bluetooth.
This patch fixes array initialization in the |Convert| functions of
|BluetoothInterface|. Designated initializers are not supported by
all compilers, so we wrap them into a macro and only used them when
possible.
This patch cleans up the interface of Bluedroid's |BluetoothScoket|
to look more similar the interface of |UnixSocketConsumer|, from
which it descends.
This patch converts Bluedroid status codes in Gecko to the
backend-neutral data type |BluetoothStatus|. All error handlers
have been adapted. The Bluedroid type |bt_status_t| only remains
in |BluetoothInterface|.
With this patch |BluetoothHandsfreeInterface| is responsible for converting all
Bluetooth data types to Bluedroid types. All callers have been adapted.
The linker mixes up |ConnectResultHandler| from BluetoothSocket.cpp
and BluetoothHfpManager.cpp. Consequently one of them gets removed
when linking libxul.so.
This patch works around the problem by renaming |ConnectResultHandler|
in BluetoothSocket.cpp to |ConnectSocketResultHandler|.
When sending a |BluetoothInterfaceRunnable3<>| to the main thread,
in the case of BluetoothSocketResultHandler, the connect and accept
operations transfer string objects by reference from the I/O thread.
When the reference is accessed, the actual string might be removed
already.
The patch fixes the problem by storing the strings as value in the
runnable object.
The Bluedroid code uses indices into global arrays while pairing
with devices. These arrays might get changed in between and the
indices become incorrect. The result is undefined.
The patch fixes the problem by using the value, a reply runnable,
directly for array lookups. No indices are required.
This bug was fixed in bluetooth2/ already, but not yet backported.
Recent patches to Bluetooth introduced asynchronous initialization of
profile manager. The code in hfp-fallback was not adapted then. This
patch updates the broken code.
