ABI Compliance: abi-compliance-checker reports 99% binary compatibility and 81.4% source compatibilty between version 0.0.5 and 0.1. - Binary compatibility: 99% - Source compatibility: 81.4% - Total binary compatibility problems: 4, warnings: 2 - Total source compatibility problems: 165, warnings: 7 Now that we have funtional ABI validation, the soname has been updated from libcamera.so.0.0.5 to libcamera.so.0.1. Future releases will now maintain the same soname until an ABI breakage is detected to reduce the repackaging and rebuilding of other components that may use libcamera. The abi-compatibility report can now be generated with the new utility './utils/abi-compat.sh'. Key differences here are due to preventing the installation of internal and private headers in the packaging process, and most of this API compatibility should not be visible to applications with the exception of: - Camera::generateConfiguration ( StreamRoles const& roles ) The StreamRoles type definition has been removed. This is now handled as a Span<StreamRole> to prevent unnecessary allocations and copies. - CameraManager::addCamera ( std::shared_ptr<struct Camera> camera, std::vector<unsigned long>const& devnums ) - CameraManager::get ( dev_t devnum ) - CameraManager::removeCamera ( std::shared_ptr<struct Camera> camera ) These functions of the CameraManager were for use exclusively by the V4L2 adaptation layer, and not intended for use by applications.

2023-05-01meson: Ignore -Wredundant-move with gcc-13 and newerLaurent Pinchart
Starting from 13.1, gcc implements the C++23 version of automatic move from local variables in return statements (see https://en.cppreference.com/w/cpp/language/return). As a result, some previously required explicit `std::move()` in return statements generate warnings. This is the case when a function returns an object whose type is a class derived from the class type the function returns: struct U { }; struct T : U { }; U f() { T t; return t; } Up to C++20, the automatic move from local variables selects the move constructor of class U, which is not the move constructor of the expression. Overload resolution is then performed a second time, with t considered as an lvalue. An explicit `std::move(t)` is needed in the return statement to select the U move constructor. Starting from C++23, `t` is treated as an xvalue, and the U move constructor is selected without the need for an explicit `std::move(t)`. An explicit `std:move()` then generates a redundant-move warning, as in the valueOrTuple() function in src/py/libcamera/py_helpers.cpp. Omitting the `std::move()` silences the warning, but selects the copy constructor of U with older gcc versions and with clang, which negatively impacts performance. The easiest fix is to disable the warning. With -Wpessimizing-move enabled, the compiler will still warn of pessimizing moves, only the redundant but not pessimizing moves will be ignored.

2023-04-05meson: Really fix git version parsingLaurent Pinchart
The previous attempt to fix git version parsing in commit d34cefad1791 ("meson: Fix git version parsing") was too naive, and didn't take into account cases where the libcamera git version contains no or multiple '+' signs. Fixing this is more complex than a one-liner change, as meson doesn't support Python-style slicing of arrays or a length method on strings. The simplest and most versatile option is to patch the version string in the gen-version.sh script. Do so, and clarify the comments related to version handling in meson.build.

2023-01-30meson: Rework automatic pipeline selectionKieran Bingham
The supported pipelines are listed in three places: the meson_options.txt file, the defined array when a user selects -Dpipelines="all", and arrays defined when the default -Dpipelines="auto" is selected. This can be hard to maintain and error prone. Rework the definition of pipeline selection to a single table which specifies the architecture(s) that the pipeline handler supports and iterate it to handle the special cases for 'all', 'auto' and 'test'. The current behaviour such that 'all' takes precedence over 'auto' is maintained, and 'test' is now extended such that additional test pipeline handlers can easily be introduced. The existing implementation defines the i.MX8-ISI and RKISP1 pipeline handlers as only supported by 'aarch64'. This conversion changes the behaviour such that those pipeline handlers are now supported on both 'arm' and 'aarch64' as each of those platforms could support a 32-bit ARM build.

Not all C libraries include support for locale objects (locale_t) and the strto*_l() family of functions. A notable example is uClibc that can be compiled with a hardcoded "C" locale. Compilation then fails as the newlocale(), freelocale() and strtod_l() functions are not defined. Fix the compilation breakage by checking for the availability of the locale_t type, and fall back to strtod() when the type isn't available. This may not lead to the correct result if support for locale objects isn't available and the locale isn't hardcoded to "C", but that is such a corner case that we will likely never encounter it.

Meson introduces a .replace() method in version 0.58.0. However we aim to restrict ourselves to 0.56 meson features, as released by Debian stable. The recent introduction of release management infrastructure makes use of the .replace() method to fix up the version string when there is a mis-match between the release version and any (lack) of tags in the git version description. This breaks when built on systems with only meson 0.56.

2022-10-13meson: Shared Object version handlingKieran Bingham
The libcamera project is not yet ready to declare ABI nor API stability, but it will benefit the community to be able to provide more regular release cycles to determine 'versioned' points of history. Ideally, these releases will be made at any ABI breakage, but can be made at arbitary time based points along the way. To support releases which may not be ABI stable, declare the soversion of both the libcamera and libcamera-base library to be dependant upon both the major minor and patch component of the project version. As part of this, introduce a new 'Versions' summary section to highlight the different version components that may become apparent within any given build. Bumping versions may leave dangling libcamera.so.* symlinks in build directories. This will confuse Doxygen which will print during its directory scanning phase a warning that the symlink can't be read. As we don't need Doxygen to follow symlinks, disable it with EXCLUDE_SYMLINKS.

Usage of find_library() to find dependencies that libcamera needs to compile against can lead to the library being found even if the corresponding headers are not installed. This will then result in a compilation failure. Switch to dependency() for libdw, libunwind and lttng-ust to fix this, all three libraries come with a pkgconfig file that is usually installed by the distribution package that contains the library headers.

"ipa_modules" stores the value of the ipas meson build option. IPAs are enabled if and only if there is an enabled pipeline for an IPA listed in "ipa_modules" array. It is basically the intersection of pipelines and ipa_modules array. In order to correctly report which IPAs get enabled, let's create a new array storing this intersection.

2022-07-07meson: Correctly pass the global include to the compilerEli Schwartz
It's not safe to assume `-include config.h` works, since this depends on the functionality of the compiler that the cwd when running the compiler is searched first. When libcamera is included as a Meson subproject, the cwd of the compiler is the cwd of the main project, not of libcamera's build dir, and thus cannot be found. Instead, pass the include filename as a path based on the current build dir.

2022-01-03meson: reduce required version to 0.53Christian Rauch
Building the libcamera Android layer currently makes use of features from meson 0.55. The core libcamera framework in the default configuration without android enabled uses the 'summary' feature available in 0.53, and is the lowest supportable meson version if the Android HAL is excluded. Ubuntu 20.04 LTS currently provides meson 0.53 and represents an acceptable minimum version to support. Platforms utilising the Android component will have full control over their build environment and can ensure that they provide a more recent version of meson. Reduce the supported meson version for the project to 0.53 to facilitate building on more distributions without having to manually update the meson package. Meson will output a warning that features not available in 0.53 are used if the Android HAL is enabled. This is considered as an acceptable middleground to improve the experience on the latest Ubuntu LTS, until 22.04 LTS is released and provides a newer meson version.

2021-10-19build: Preserve upstream git versioning using meson distNaushir Patuck
When distributions build and package libcamera libraries, they may not necessarily run the build in the upstream source tree. In these cases, the git SHA1 versioning information will be lost. This change addresses that problem by requiring package managers to run 'meson dist' to create a tarball of the source files and build from there. On runing 'meson dist', the utils/run-dist.sh script will create a .tarball-version file in the release tarball with the version string generated from the existing utils/gen-version.sh script. The utils/gen-version.sh script has been updated to check for the presence of this .tarball-version file and read the version string from it instead of creating one.

The MESON_SOURCE_ROOT environnement variable does not get set when called from the meson vcs_tag() function, but does when called from the run_command() function, so that cannot be used either.

In preparation for using the AGC through the new algorithm interfaces, convert the existing code to use the new function types. Now that the process call is rewritten, re-enable the compiler flag to warn when a function declaration hides virtual functions from a base class (-Woverloaded-virtual). We never use converged_ so remove its declaration. The controls may not need to be updated at each call, but it should be decided on the context side and not by a specific call by using a lock status in the Agc structure for instance. As the params_ local variable is not useful anymore, remove it here too.

Introduce three functions in the Algorithm class to manage algorithms: - configure which is called when IPA is configured only - prepare called on EventFillParams event at each frame when the request is queued - process called on EventStatReady event at each frame completion when the statistics have been generated. The existing AGC implementation already has a function named process(), though it has different arguments. Adding the new virtual process() interface causes a compiler warning due to the AGC implementation overloading a virtual function, even though the overload can be resolved correctly.

2021-05-26android: Fix file system library usage on gcc 7 and 8Laurent Pinchart
On gcc versions older than 9, the file system library, used by the Android camera HAL configuration file parser, is implemented in a separate static library. Furthermore, on gcc 7, it's provided in the std::experimental namespace. This breaks compilation of the HAL on gcc 7, and linking on gcc 8. Fix the compilation issue by conditionally including <experimental/filesystem> and creating a namespace alias in std, and the link issue by linking to libstdc++fs on gcc versions older than 9. The inclusion of <experimental/filesystem> is a bit of a hack, and when we'll start using the file system library in another compilation unit, we should then move all this to an internal helper to abstract the compiler version.
