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.
Profile managers use the new class |BluetoothProfileResultHandler|
to signal the result of initializing of cleaning up operations to
|BluetoothServiceBluedroid|. |BluetoothServiceBluedroid| proceeds
once all profile handlers have finished.
Future patches will build upon this patch to create completely
asynchronous profile managers.
This patch adds a missing include statement for <errno.h> to
BluetoothInterface.cpp. This fixes the build for flatfish
devices. For safety, the patch also adds an include statement
for <unistd.h>, which might be necessary for several functions.
Currently, BluetoothSocket leaks its file descriptor on close
operations. With this patch when Gecko closes an instance of
BluetoothSocket, the file descriptor is now closed as well.
This patch removes all code related to socket setup from Bluedroid's
BluetoothSocket. The socket setup is handled by BluetoothInterface;
transparantly to its users.
Since most of the socket setup is now hidden, a comment was added to
DroidSocketImpl that explains the connection phases in server and
client.
This patch moves the accept phase of Bluedroid's |Listen| to the
implementation of BluetoothInterface. |BluetoothInterface::Accept|
handles Bluedroid's socket-setup messages and executes the result
handler with the received file descriptor and data.
Bluedroid's internal socket setup transfers 2 messages and possibly
a file descriptor as the first data of a socket connection.
This patch moves the socket-setup code for the |Connect| call to
the implementation of BluetoothInterface. BluetoothSocket only
handles the socket setup of |Listen|, and general socket state.
In preparaton of moving the Bluedroid socket setup to BluetoothInterface,
this patch introduces connection states for Bluetooth sockets. There are
4 states,
- Disconnected,
- Listening,
- Connecting, and
- Connected.
All sockets start in Disconnected and transition to Connected via one
of the other states. Server socket transition through Listening, Client
sockets transition through Connecting. There is currently a lot of code
duplication in read and write methods. This will be cleaned up when the
connection setup is handled by BluetoothInterface.
