This is needed in order to interrupt event loops\ngracefully.\n\nThe series starts in patch 1/4 by adding a test that fails, to outline\nmissing EINTR support, which is then fixed by patch 2/4. It ends with\nanother test case for the new EventDispatcher::interrupt() method.\n\nLaurent Pinchart (4):\n tests: Test event dispatcher interruption by signal\n libcamera: event_dispatcher_poll: Handle interrupted ppoll() calls\n libcamera: event_dispatcher: Add interrupt() function\n tests: event-dispatcher: Add processEvents() interruption test\n\n include/libcamera/event_dispatcher.h | 2 +\n src/libcamera/event_dispatcher.cpp | 10 ++\n src/libcamera/event_dispatcher_poll.cpp | 82 ++++++++++----\n src/libcamera/include/event_dispatcher_poll.h | 4 +\n test/event-dispatcher.cpp | 103 ++++++++++++++++++\n test/meson.build | 9 +-\n 6 files changed, 184 insertions(+), 26 deletions(-)\n create mode 100644 test/event-dispatcher.cpp"}
