db31477433 test: log: log_process: Fix uninitialized variable on process exit failure
If the process fails to exit before the timeout, the
LogProcessTest::exitStatus_ variable gets used uninitialized. Fix it by

03526e58d1 tests: gstreamer: Fix compiler error with gcc 8.4.0
The provider g_autoptr variable introduced by commit adb1bbb748
("tests: gstreamer: Test cameras' enumeration from GstDeviceProvider")
is left uninitialized when declared. The cleanup function could thus get
called on an unitialized variable if the scope was exited before the
variable gets initialized. This can't occur here, but gcc 8.4.0 still
complains about it:

/usr/include/glib-2.0/glib/gmacros.h: In member function ‘virtual int GstreamerDeviceProviderTest::run()’:
/usr/include/glib-2.0/glib/gmacros.h:1049:27: error: ‘provider’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
     { if (_ptr) (cleanup) ((ParentName *) _ptr); }                                                              \
                           ^
../test/gstreamer/gstreamer_device_provider_test.cpp:37:32: note: ‘provider’ was declared here
   g_autoptr(GstDeviceProvider) provider;

Silence the error by initializing the variable to NULL at declaration
time. This is a good practice in any case, as later refactoring could
otherwise introduce a scope exit before initialization.

d48e15d571 test: py: Fix test failure when ASan is enabled
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.

121b5de329 test: v4l2_compat: Enable test with ASan
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.

To LD_PRELOAD the ASan runtime, the path to the binary needs to be

e0e54965df libcamera: base: utils: Drop defopt
utils::defopt causes compilation issues on gcc 8.0.0 to gcc 8.3.0,
likely due to bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86521
that was fixed in gcc 8.4.0. gcc 8.3.0 may be considered old (libcamera
requires gcc-8 or newer), but it is shipped by Debian 10 that has LTS
support until mid-2024.

As no workaround has been found to fix compilation on gcc 8.3.0 while
still retaining the functionality of utils::defopt, remove it from the
libcamera base library. This change could be reverted once support for
gcc-8 will be dropped.

7615f58f9b test: yaml-parser: Test out-of-range checks on integer parsing
Add 16-bit integer parsing tests, including a test to verify the
out-of-range checks when parsing 32-bit integers as 16-bit values. That
test currently fails.

629e65b15b test: yaml-parser: Centralize integer parse checks
Centralize the signed and unsigned integer parse checks to avoid code
duplication. The diffstat isn't very impressive at this point, but this
will help more when adding 8-bit and 16-bit integer tests.

bf3dbaece9 py: Switch to non-blocking eventfd
Blocking wait can be easily implemented on top in Python, so rather than
supporting only blocking reads, or supporting both non-blocking and
blocking reads, let's support only non-blocking reads.

45736468c8 libcamera: v4l2_videodevice: Reintroduce toV4L2PixelFormat()
This is a partial revert of commit 395d43d6d7 ("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().

48c106429a libcamera: base: utils: Provide defopt to simplify std::optional::value_or() 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.

6724800f14 test: yaml-parser: Test dictionary items ordering
While YAML specifies that mappings are unordered, the Raspberry Pi IPA
relies on elements being ordered as in the YAML data. To replace the
dependency on boost with the YamlParser class, we thus need to guarantee
that the order is preserved. Update the corresponding unit test to
ensure this. The test currently fails at the YamlParser doesn't
correctly preserve the order, this will be fixed by the next commit.

This commit should be reverted when the Raspberry Pi IPA updates to a
new tuning data format and drops support for the old format.

feb8c9be78 libcamera: yaml_parser: Replace ok flag to get() with std::optional
The YamlObject::get() function takes a default value and an optional
bool ok flag to handle parsing errors. This ad-hoc mechanism complicates
error handling in callers.

A better API is possible by dropping the default value and ok flag and
returning an std::optional. Not only does it simplify the calls, it also
lets callers handle errors through the standard std::optional class
instead of the current ad-hoc mechanism.

Provide a get() wrapper around std::optional::value_or() to further
simplify callers that don't need any specific error handling.
