2022-12-24test: py: Fix test failure when ASan is enabledLaurent Pinchart
When the address sanitizer is enabled, the Python unit tests fail due to the link order runtime check as the Python interpreter is (generally) not linked to ASan. Fix this by LD_PRELOAD'ing the ASan runtime. We have to disable the leak detector as the Python interpreter itself leaks memory, which would result in test failures. To LD_PRELOAD the ASan runtime, the path to the binary needs to be known. gcc gives us a generic way to get the path, but that doesn't work with clang as the ASan runtime file name depends on the clang version and target architecture. We thus have to keep the Python test disabled when ASan is enabled and libcamera is compiled with clang.

When libcamera is compiled with the address sanitizer enabled, the v4l2_compat test generates failures in the link order runtime check, as the host v4l2-ctl and v4l2-compliance tools are not (generally) linked to ASan. For this reason, the test is disabled, which sadly shrinks test coverage. Fix this by loading the ASan runtime using LD_PRELOAD. This needs to be done from within the v4l2_compat_test.py Python script, as the Python interpreter itself leaks memory and would cause test failures if run with ASan.

This is a partial revert of commit 395d43d6d75b ("libcamera: v4l2_videodevice: Drop toV4L2PixelFormat()") The function was removed because it incorrectly maps non-contiguous V4L2 format variants (ie V4L2_PIX_FMT_YUV420M) to the API version supported by the video device (singleplanar API and multiplanar API). It was decided at the time to remove the function and let its users call directly V4L2PixelFormat::fromPixelFormat() which accepts a 'multiplanar' flags. As we aim to associate multiple V4L2PixelFormat to a single libcamera format, the next patches will verify which of them is actually supported by the video device. For now, return the contiguous version unconditionally. Re-introduce V4L2VideoDevice::toV4L2PixelFormat() and convert all the V4L2PixelFormat::fromPixelFormat() users to use it. The V4L2 compatibility layer is the only outlier as it doesn't have a video device to poke, hence it still uses V4L2PixelFormat::fromPixelFormat(). Next patches will implement the device format matching logic and handle the non-contiguous plane issue in V4L2VideoDevice::toV4L2PixelFormat().

usage The std::optional<T>::value_or(U &&default_value) function returns the contained value if available, or default_value if the std::optional has no value. If the desired default value is a default-constructed T, the obvious option is to call std::optional<T>::value_or(T{}). This approach has two drawbacks: - The \a default_value T{} is constructed even if the std::optional instance has a value, which impacts efficiency. - The T{} default constructor needs to be spelled out explicitly in the value_or() call, leading to long lines if the type is complex. Introduce a defopt variable that solves these issues by providing a value that can be passed to std::optional<T>::value_or() and get implicitly converted to a default-constructed T.

Move the logic for checking the availability of cameras from multi_stream_test to gstreamer test base class. Since single_stream_class always assumes that a camera is available on the system (which is not always the case for e.g. RPi in CI/CD environments) it makes sense to have the availability check in the base class. If no cameras are available, the behaviour should be to skip instead of a failure. We currently have 2 tests for gstreamer differing based on number of streams supported by the camera. Hence, the camera availability is checked in conjunction with the number of the streams required by the derived class.

2022-07-06test: delayed_controls: Remove sequenceOffsetJacopo Mondi
Commit 6f539a6d2fa9 ("delayed_controls: Remove reduandant firstSequence_") removed support for frame number start offset from the DelayedControls class, as it is now guaranteed that the first sequence number as it comes from the V4L2VideoDevice will always be 0. However the delayed_controls.cpp unit still has two tests that passes a non-zero first sequence number to the DelayedControl class, causing the test to spin forever and consequentially fail. Remove the two tests from the unit to fix this. The first removed test was testing the class against frame start sequence numbers greater than zero and can safely be removed. The second test was instead validating the class against sequence number overflow, which is now not possible to test anymore as the DelayedControls class now assumes 0 as first frame sequence number.
