2021-08-05Documentation: application-developer: Recommend unique_ptr for CameraManagerdevKieran Bingham
The CameraManager object should be deleted when it is no longer used to prevent it from leaking. When the application closes, the memory will be released, but it would show up in reports from memory validation tools such as valgrind if not handled correctly. Recommend best-practices in the guide and ensure it is automatically cleaned up when the CameraManager goes out of scope. Signed-off-by: Kieran Bingham <kieran.bingham@ideasonboard.com>

2021-08-05libcamera: v4l2_videodevice: Handle unexpected buffersKieran Bingham
A kernel bug can lead to unexpected buffers being dequeued where we haven't entered the buffer in our queuedBuffers_ list. This causes invalid accesses if not handled correctly within libcamera, and while it is a kernel issue, we must protect against unpatched kernels. Handle unexpected buffers by returning a nullptr, and move cache management after the validation of the buffer.

2021-08-04android: Override camera as "Internal" provided found in HAL configUmang Jain
Currently, all UVC cameras are reported with CameraLocationExternal [1] by libcamera-core since there is no universal information or standard, to know the location of these cameras. However, in the libcamera HAL layer, we can make an informed decision whether it's external or internal, simply by checking its presence in the HAL configuration file. The CameraHalManager will now assign the numerical id of the camera accordingly when initializing the CameraDevice, based on the camera facing value set in the HAL config file.

Currently CameraDevice wrapper is created first and then HAL config validity is checked. If the validity checks fail, the code path will simply return, in which case, creating CameraDevice seems a futile exercise. This patch defers the creation of CameraDevice wrapper until the HAL config validity is checked for internal cameras. This will also enable us to infer a few things beforehand, by reading the config file before creating the CameraDevice wrapper.

2021-08-03libcamera: base: class: Don't pass Extensible pointer to Private constructorLaurent Pinchart
The Extensible and Extensible::Private classes contain pointers to each other. These pointers are initialized in the respective class's constructor, by passing a pointer to the other class to each constructor. This particular construct reduces the flexibility of the Extensible pattern, as the Private class instance has to be allocated and constructed in the members initializer list of the Extensible class's constructor. It is thus impossible to perform any operation on the Private class between its construction and the construction of the Extensible class, or to subclass the Private class without subclassing the Extensible class. To make the design pattern more flexible, don't pass the pointer to the Extensible class to the Private class's constructor, but initialize the pointer manually in the Extensible class's constructor. This requires a const_cast as the o_ member of the Private class is const.
