The interface is asynchronous and bi-directional.\n\n* Changes since v1\n- Add a bugfix for Timer which prevented the test case to function \n properly.\n- Add destructor to close the IPC channel.\n- Rename attach() to bind().\n- Add isBound() mehtod.\n- Rework signal emitted for incoming data to Signal \n readyRead.\n- Make payload argument in send() const at the cost of adding a \n const_cast().\n- Dropped unused master_ property.\n- Updated documentation, thanks Laurent!\n- Add a call() method in the test case to simplify test logic.\n- Use dup() instead of opening the same file path multiple times.\n\n* Changes since RFC\n- Switch to an event notifications and signals for the ingress code\n path, making the interface asynchronous.\n- Removed any protocol helpers in the IPC object, a protocol should be\n implemented on top of the IPC.\n- Added documentation.\n- Switched to SOCK_DGRAM.\n- Send both data and file descriptors in the same sendmsg().\n- Fixed spelling and silly errors in the code.\n- Merged test case in a single binary.\n\nNiklas Söderlund (3):\n libcamera: timer: Stop timer when it is deleted\n libcamera: ipc: unix: Add a IPC mechanism based on Unix sockets\n test: ipc: unix: Add test for IPCUnixSocket\n\n include/libcamera/timer.h | 1 +\n src/libcamera/include/ipc_unixsocket.h | 57 ++++\n src/libcamera/ipc_unixsocket.cpp | 312 ++++++++++++++++++++\n src/libcamera/meson.build | 2 +\n src/libcamera/timer.cpp | 5 +\n test/ipc/meson.build | 12 +\n test/ipc/unixsocket.cpp | 390 +++++++++++++++++++++++++\n test/meson.build | 1 +\n 8 files changed, 780 insertions(+)\n create mode 100644 src/libcamera/include/ipc_unixsocket.h\n create mode 100644 src/libcamera/ipc_unixsocket.cpp\n create mode 100644 test/ipc/meson.build\n create mode 100644 test/ipc/unixsocket.cpp"}
