Source files in libcamera start by a comment block header, which
includes the file name and a one-line description of the file contents.
While the latter is useful to get a quick overview of the file contents
at a glance, the former is mostly a source of inconvenience. The name in
the comments can easily get out of sync with the file name when files
are renamed, and copy & paste during development have often lead to
incorrect names being used to start with.
Readers of the source code are expected to know which file they're
looking it. Drop the file name from the header comment block.
The change was generated with the following script:
----------------------------------------
dirs="include/libcamera src test utils"
declare -rA patterns=(
['c']=' \* '
['cpp']=' \* '
['h']=' \* '
['py']='# '
['sh']='# '
)
for ext in ${!patterns[@]} ; do
files=$(for dir in $dirs ; do find $dir -name "*.${ext}" ; done)
pattern=${patterns[${ext}]}
for file in $files ; do
name=$(basename ${file})
sed -i "s/^\(${pattern}\)${name} - /\1/" "$file"
done
done
----------------------------------------
This misses several files that are out of sync with the comment block
header. Those will be addressed separately and manually.

The GStreamer single stream test uses the following pipeline:
libcamerasrc ! videoconvert ! fakesink
The videoconvert element isn't useful as the data is thrown away by the
fakesink anyway. We can shorten the pipeline to
libcamerasrc ! fakesink
to save CPU time and to avoid depending on the gstreamer1.0-plugins-base
package to run the unit tests.
The test could be further simplified by replacing
gst_parse_bin_from_description_full() with gst_element_factory_make(),
now that we only add one element to the bin. The extra cost incurred by
the bin only impacts initialization time, and using a bin will make it
easier to add other elements in the future if needed. Keep the bin, and
only drop the videoconvert element.

The provider g_autoptr variable introduced by commit adb1bbb748a1
("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.

Multistream test failed with the following logs, to run on Raspberry Pi 4 due
to a bug introduced in one of the recent patches refactoring the code
that fails to set the camera-name property with a valid camera id
string.
WARN libcamerasrc gstlibcamerasrc.cpp:347:gst_libcamera_src_open:<libcamera> error: Could not find a camera named ''.
WARN libcamerasrc gstlibcamerasrc.cpp:347:gst_libcamera_src_open:<libcamera> error: libcamera::CameraMananger::get() returned nullptr
This patch assigns the camera->id() to the variable cameraName_ that is
later used to set element property "camera-name" needed to call the
specific camera which supports multistreams. Move the code to set
element property "camera-name" to base class GstreamerTest.

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.

In gstreamer, when elements are created, usually a floating [1]
reference is returned which simply means, there is no ownership
transfer (yet). Once can simply check for NULL and return through
an error path, without bothering to clean up. Hence, g_autoptr is
not much of help here.
If the NULL checks have been passed successfully, elements are ready
to use. However, we must claim ownership/reference it before using
them via g_object_ref_sink().
This patch build upon this principle and removes the g_autoptr
from gstreamer test base class (gstreamer_test.cpp) whereever
necessary to tide up the code.

The destructor tried to check if pipeline_ is a parent of libcameraSrc_.
This was needed to be checked as if it is, cleanup of libcameraSrc_
would be handled by pipeline itself.
Since, the destructor can be called anytime, even when pipeline_ hasn't
been created, the use of pipeline_ to check if libcameraSrc_ has an
ancestor as pipeline_ caused a segmentation fault.

ASan needs to be loaded first before gstreamer is loaded. This was not
possible, so verify_asan_link_order was disabled. Better way to tackle
this issue was disabling forks on the gstreamer side.
verify_asan_link_order=0 disables the check on ASan side which checks if
ASan was loaded before any other shared objects. Since, gstreamer spawns
a child helper process while building the registry, we needed to disable
this check. But with gst_registry_fork_set_enabled() it is possible to
disable spawning this child helper process, so this ensures that ASan is
loaded before any other shared object is loaded.

This patch adds a test to test if single stream using libcamera's
gstreamer element works.
We need to work around two distinct issues with ASan when enabled in the
build:
- glib has a known leak at initialization time. This is covered by the
suppression file shipped with glib, but it's not clear how to use it
automatically. For now, disable leak detection to avoid test failures.
- GStreamer spawns a child process to scan plugins. If GStreamer is
compiled without ASan (which is likely) but libcamera is, dlopen()ing
the libcamera plugin will cause an ASan link order verification
failure. Disable the verification child processes to work around the
problem. This requires gcc 8 or newer.
