2024-08-07libcamera: Hide *::Private classes with __DOXYGEN_PUBLIC__Laurent Pinchart
The *::Private classes are part of the internal API, as their name implies. They are defined in internal headers, but implemented in the same source file as their public counterparts. This will cause Doxygen to complain about missing class definition when splitting the public and internal API documents, as the internal headers won't be parsed by Doxygen for the public API documentation. Marking the classes with \internal isn't enough. The directive prevents the documentation block from being included in the output, but this occurs at the generation stage, after the documentation blocks are parsed. Fix this by completely hidding the implementation of the *::Private classes from Doxygen using preprocessor conditional compilation. To do so, introduce a new macro, __DOXYGEN_PUBLIC__, that will be defined for the public API documentation only.

2024-08-07libcamera: Mark internal parts of public classes with \internalLaurent Pinchart
The libcamera public API exposes classes that have parts considered internal. They inherit the Extensible class, and their internal parts are split into a Private class. Those classes are defined in public API headers, and their Private counterparts are defined in internal headers sharing a common file name (in a different directory). Both headers are documented in the same source file. For instance, include/libcamera/camera.h contains the public API of the Camera class, and include/libcamera/internal/camera.h its internal counterpart. Both are documented in src/libcamera/camera.cpp. As the internal headers are not part of the public API, they need to be hidden from the future public API builds. To prepare for doing so, mark them with the \internal Doxygen directive. Hardcode the Doxygen INTERNAL_DOCS option to YES to include the internal API. This will be changed later for the public API documentation build.

2024-08-01libcamera: ipa_proxy: Report a missing configuration as a warningMilan Zamazal
When the configuration file for an IPA module is missing, it is reported as an error in the log, for example: ERROR IPAProxy ipa_proxy.cpp:149 Configuration file 'imx219.yaml' not found for IPA module 'simple' This is misleading because several pipelines use uncalibrated.yaml in such a case and can continue working. And in case of software ISP, there is currently no other configuration file so the error is always reported. On the other hand, in some other cases the presence of the configuration file is required and it is an error if it is missing. Let's introduce a new optional argument to IPAProxy::configurationFile that specifies a fallback file if the requested file is not found. If the primary requested file is not found and a non-empty fallback file is specified then a warning is logged and the fallback file is looked up. If neither the fallback file can be found then only then an error is logged and the method returns an empty string. This change has also the benefit of putting the common fallback file ("uncalibrated.yaml") pattern to a single place.

SimplePipelineHandler::match may be called several times for different pipeline configurations. Not all of these calls must succeed. For example, for TI AM69 board with a single camera attached, the following error is reported in the log even when libcamera works fine: ERROR SimplePipeline simple.cpp:1558 No sensor found This is because a sensor is found for /dev/media0 but not for /dev/media1. The error is harmless in such a case and only confuses users who may think no camera is detected at all.

2024-07-31libcamera: Avoid variable-length arraysLaurent Pinchart
Unlike in C where they have been standardized since C99, variable-length arrays in C++ are an extension supported by gcc and clang. Clang started warning about this with -Wall in version 18: src/libcamera/ipc_unixsocket.cpp:250:11: error: variable length arrays in C++ are a Clang extension [-Werror,-Wvla-cxx-extension] 250 | char buf[CMSG_SPACE(num * sizeof(uint32_t))]; | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ One simple option is to disable the warning. However, usage of VLAs in C++ is discouraged by some, usually due to security reasons, based on the rationale that developers are often unaware of unintentional use of VLAs and how they may affect the security of the code when the array size is not properly validated. This rationale may sound dubious, as the most commonly proposed fix is to replace VLAs with vectors (or just arrays dynamically allocated with new() wrapped in unique pointers), without adding any size validation. This will not produce much better results. However, keeping the VLA warning and converting the code to dynamic allocation may still be slightly better, as it can prompt developers to notice VLAs and check if size validation is required. For these reasons, convert all VLAs to std::vector. Most of the VLAs don't need extra size validation, as the size is bound through different constraints (e.g. image width for line buffers). An arguable exception may be the buffers in IPCUnixSocket::sendData() and IPCUnixSocket::recvData() as the number of fds is not bound-checked locally, but we will run out of file descriptors before we could overflow the buffer size calculation.

The musl C library, as well as the POSIX standard, define the ioctl() function's request argument as an int. glibc and uclibc, on the other hand, define it as an unsigned long. This difference between the function prototype and the implementation in the V4L2 adaptation layer causes a compilation error with musl.

2024-07-25gstreamer: allocator: Ensure camera manager stay aliveNicolas Dufresne
Without the camera manager, it is not possible to cleanly delete the FrameBufferAllocator object. Keep the camera manager alive until all the memory object have been released. A shared_ptr to the CameraManager is introduced which is itself stored as a plain pointer and allocated and released explicitly. When more than one C++ member is required, this can be refactored to use a new C++ class, but the struct _GstLibcameraAllocator is allocated and freed by glib, so it does not have automatic destruction presently.

2024-07-25utils: gen-version: Use posix compliant dateZach DeCook
The version string of libcamera is presently appended with a date/time argument in the case of a dirty tree to show further detail of when it was built. This string is generated with the iso-8601 parameter to 'date' and produces a date string in the form: "2024-06-17T22:15:30+01:00" Strict posix shells or implementations of 'date' which may be optimised for size such as the one provided by busybox or Alpine Linux may not support the '--iso-8601' flag. To support builds on those platforms, use a direct POSIX-compliant date-format string instead matching as closely as possible to the iso-8601 definition. An exact match is not possible with those restrictions so 'date %Y-%m-%dT%H:%M:%S%Z' is used which produces 2024-06-17T22:15:30BST. The use of the human readable timezone identifier provides a friendlier output for the string than a timezone offset at the expense of being less sortable in the exceptionally low risk and unlikely event of two custom builds being compared at the same time of different timezones.

2024-07-25gstreamer: pool: Replace GstAtomicQueue with deque and mutexNicolas Dufresne
The GstAtomicQueue only supports 2 threads, one pushing, and one popping. We pop and push on error cases and we may have multiple threads downstream returning buffer (using tee), which breaks this assumption. On top of which, the release function, that notifies when the queue goes from empty to not-empty relies on a racy empty check. The downstream thread that does this check is effectively concurrent with our thread calling acquire(). Fix this by replacing the GstAtomicQueue with a std::deque, and protect access to that using the object lock.

The frame context is used to store data used for processing that frame. It is later used to either act as input for other algorithms or to fill the metadata.

When the color gains are set manually it is possible to specify a gain that wrapped the hardware limits. It would also be possible to further tune the floating point limits, but that is an error prone approach. So the limits are imposed on the integers, just before writing to the hardware.
