39f01e9185 py: gen-py-controls: Convert to jinja2 templates
Jinja2 templates help separate the logic related to the template from
the generation of the data. The python code becomes much clearer as a
result.

As an added bonus, we can use a single template file for both controls
and properties.

5c1cb5e5bc py: gen-py-controls: Use Control class
Replace manual extraction of data from YAML with the Control helper
class. This centralizes YAML parsing and avoids manual mistakes.

a5f12d2eb3 meson: utils: Provide environment for Python scripts
Python scripts run as part of the build process need to take a few
actions specific to the environment in which they operate. One of those
is disabling the Python bytecode cache, to avoid writing .pyc files to
the source tree. This is done manually in the IPC generate.py and
parser.py scripts.

The current implementation is not ideal because it hardcodes in the
scripts information related to the environment in which they operate. As
those scripts are part of libcamera this is more of a theoretical issue
than a practical one. A second issue is that future Python scripts will
need to duplicate similar mechanisms, resulting in a higher maintenance
burden.

Address the issue with a different approach, by creating a meson
environment for the Python scripts, and passing it to the
custom_target() functions. The environment only disables the bytecode
cache for now.

The diffstat shows an increase in code size. This is expected to be
offset by usage of the environment for more Python scripts, as well as
support of more variables in the environment.

cbffcbe362 meson: Fix mismatch in controls and properties generated file names
The header for controls and properties are generated from the
control_ids.h.in and property_ids.h.in templates respectively, and the
generated files are named control_ids.h and property_ids.h.

For sources, the templates are named control_ids.cpp.in and
property_ids.cpp.in, but the output files are named controls_ids.cpp and
properties_ids.cpp. This discrepancy causes confusion. Fix it.

b8d318ebeb meson: Store controls and properties YAML files in variables
When generating control headers, the YAML files to be used are
determined dynamically based on the selected pipeline handlers. As part
of this process, the build system populates an array of meson File
objects used as an input for the control headers generation custom
target, as well as an array of file names (as strings). The file names
array is later used to generate the control source files for the
libcamera core, as well as the source code for controls support in the
Python bindings.

Both of the source code generators manually turn the array of file names
into File objects. This duplicates code and reduces readability. A third
similar implementation has also been proposed to generate control
support sources in the GStreamer element, making the issue worse.

To simplify this, store File objects instead of file names in the
controls_files array. As the meson configuration summary doesn't support
File objects, create a separate controls_files_names to store the file
names for that sole purpose.

The exact same process occurs for properties, address them the same way.

7dc38adcb5 Documentation: Split public/private documentation
The API reference pages generated by Doxygen are comprehensive, but
therefore quite overwhelming for application developers who will
likely never need to use the majority of the library's objects. To
reduce the complexity of the documentation, split it into two runs of
doxygen.

The first run of doxygen is for the public API. We pass a specific list
of source files to parse, which is built from the arrays of public
headers and sources in meson build files. This ensures that we only
generate the documentation for code from those files.

A custom Python script is needed to add the list of input files to
Doxyfile, as several of the objects included in the header and source
array are custom_tgt objects, which can't be handled as strings to
populate a variable in the configuration data.

The headers defining the Extensible and Object classes (class.h and
object.h respectively), as well as the corresponding source files, are
excluded from the public API documentation despite being referenced in
the meson public headers and sources arrays. This is due to the fact
that public API classes inherit from Extensible and Object, making the
Extensible and Object classes part of the public ABI. Those two base
classes are however implementation details and must not be accessed
directly by application code.

The second run of doxygen is for the internal API. This contains
documentation for all of the library's objects as it currently does.
This set will now be output into build/Documentation/internal-api-html.

1045522af9 libcamera: ipa_manager: Remove singleton requirement
The IPAManager class implements a singleton pattern due to the need of
accessing the instance in a static member function. The function now
takes a pointer to a PipelineHandler, which we can use to access the
CameraManager, and from there, the IPAManager.

Add accessors to the internal API to expose the CameraManager from the
PipelineHandler, and the IPAManager from the CameraManager. This
requires allocating the IPAManager dynamically to avoid a loop in
includes. Use those accessors to replace the IPAManager singleton.

Update the IPA interface unit test to instantiate a CameraManager
instead of an IPAManager and ProcessManager, to reflect the new way that
the IPAManager is accessed.

ff26e21339 libcamera: Hide *::Private classes with __DOXYGEN_PUBLIC__
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.

697bcf5b10 libcamera: Mark internal parts of public classes with \internal
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.

6c17996879 libcamera: ipa_proxy: Report a missing configuration as a warning
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.

This is because a sensor is found for /dev/media0 but not for

users who may think no camera is detected at all.  Let's change the
error to info and add the device node to the message to indicate the

efc7a85bc0 libcamera: shared_mem_object: Prevent memfd from shrinking or growing
The memfd underlying the SharedMem object must not shrink, or memory
corruption will happen. Prevent this by setting the shrink seal on the
file. As there's no valid use case for growing the memory either, set
the grow seal as well.

93d9751945 libcamera: base: memfd: Handle uClibc compatibility with function wrapper
uClibc doesn't provide memfd_create(), which led libcamera to open-code
the call using syscall(). Sprinkling the code with #ifdef's isn't the
most readable option, so improve it by providing a local implementation
of memfd_create(), and call the function unconditionally from
MemFd::create(). This makes the main code path more readable.

7f33dfc100 libcamera: Avoid variable-length arrays
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.

c9152bad5c gstreamer: Fix width and height range handling
This changes is fixing critical error message
"gst_value_set_int_range_step: assertion 'start < end' failed" observed
when building GStreamer caps from a stream configuration whose size
range holds a single size.

GStreamer range step definition requires distinct min and max values
definitions, otherwise above error message is output.

libcamera SizeRange instance may return a single size leading to
identical min and max values. Add a conditional check where the min and
max of the range are distinct during iterating the supported sizes for
each pixelformat.

To prevent appending structures that are already expressed with this
update, gst_caps_merge_structure() is used in place of
gst_caps_append_structure().

83b3141178 v4l2: v4l2_compat: Fix ioctl() prototype with musl C library
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. Fix it
by detecting the function prototype and declaring the libcamera ioctl()
handler accordingly.

0c9862d6e3 gstreamer: allocator: Ensure camera manager stay alive
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.

04f1f20337 gstreamer: pool: Replace GstAtomicQueue with deque and mutex
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.
