It was leaving behind a leaked reference which\n was causing unclean unbind->bind operation (due to dangling dirs)\n for the hotplug unit test to run.\n - Simplify hotplug unit test with use of std::ofstream.\n - Change CameraManager::Private::addCamera() signature to accept\n Camera arg as pass-by-value instead of pass-by-reference.\n - qcam: Finalize HotplugEvent naming with ::HotPlug and ::HotUnplug\n - Few small improvements in commit messages and rebase. \n\n\nUmang Jain (6):\n libcamera: CameraManager: Drop the vector of created PipelineHandlers\n libcamera: camera_manager: Refactor pipelines creation into separate\n function\n libcamera: device_enumerator: Emit a signal when a new devices are\n added\n libcamera: camera_manager: Introduce signals when a camera is\n added/removed\n qcam: main_window: Introduce initial hotplug support\n tests: Introduce hotplug hot-unplug unit test\n\n include/libcamera/camera_manager.h | 6 +-\n .../libcamera/internal/device_enumerator.h | 4 +\n src/libcamera/camera_manager.cpp | 60 +++++++--\n src/libcamera/device_enumerator.cpp | 13 ++\n src/libcamera/pipeline_handler.cpp | 2 +-\n src/qcam/main_window.cpp | 76 +++++++++++\n src/qcam/main_window.h | 6 +\n test/hotplug-cameras.cpp | 124 ++++++++++++++++++\n test/meson.build | 1 +\n 9 files changed, 277 insertions(+), 15 deletions(-)\n create mode 100644 test/hotplug-cameras.cpp"}
