2024-08-15meson: Move all code generation scripts to utils/codegen/Laurent Pinchart
We have multiple code generation scripts in utils/, mixed with other miscellaneous utilities, as well as a larger code base based on mojom in utils/ipc/. To make code sharing easier between the generator scripts, without creating a mess in the utils/ directory, move all the code generation code to utils/codegen/.

2024-08-15meson: Fix mismatch in controls and properties generated file namesLaurent Pinchart
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.

2024-08-15meson: Store controls and properties YAML files in variablesLaurent Pinchart
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.

2024-08-14Documentation: Split public/private documentationDaniel Scally
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.

2024-08-12utils: checkstyle.py: Rework commit message parsingLaurent Pinchart
When parsing commit messages, the Commit class tries to optimize the process by invoking git-show once only, extracting both the commit author, title and modified files in one go. As a result, the derived Amendment class needs to implement the commit parsing separately, as the modified files need to be extracted differently for amendments (and the commit ID also needs to be retrieved differently). Furthermore, because of the list of named files, extracting the trailers needs to invoke git-show separately. Improve the situation by reworking the commit message parsing in three steps. In the first step, use git-show to extract the commit ID, author, title and body. In the second step, invoke git-interpret-trailers to extract the trailers from the body that was previously extracted. The third and final step extracts the list of modified files, using different methods for regular commits and amendments. This allows sharing code for the first two steps between the Commit and Amendment classes, making the code simpler. The Commit class still invokes git three times, while the Amendment class runs it three times instead of four, improving performance slightly.

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.

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.

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.

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.

The argument name is different in the declaration and the definition. Let's use the same one in both, namely `name'.

2024-08-01libcamera: simple: Log a missing sensor in a better wayMilan Zamazal
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. Let's change the error to info and add the device node to the message to indicate the error is specific to the given media only. It's up to the callers to report a fatal error condition if libcamera cannot work due to no matching pipeline configuration.
