2022-10-20libcamera: base: log: Fix LogCategory creation issuesTomi Valkeinen
Each declaration of a LogCategory will create a new LogCategory, and will be stored in an unordered_set Logger::categories_. This means that when a plugin .so is unloaded and loaded, as happens when destructing and creating a CamereManager, we'll get duplicate categories. The Logger::registerCategory docs say "Log categories must have unique names. If a category with the same name already exists this function performs no operation.". The code does not comply with this. We solve the issue with two changes: Change the unordered_set to a vector for simplicity, as there's no need for an unordered_set. Instead of using the LogCategory constructor to create new categories in _LOG_CATEGORY() macro, use a factory method. The factory method will return either an existing LogCategory if one exists with the given name, or a newly created one.

2022-10-20libcamera: base: log: Fix use of freed nameTomi Valkeinen
LogCategory just stores the char * that was given to it in the constructor, i.e. it refers to memory "outside" LogCategory. If the LogCategory is defined in a .so that is unloaded, then it leads to the LogCategory pointing to freed memory, causing a crash. Fix this by taking a copy of the name by using a std::string instead of just storing the pointer.

2022-10-18utils: ipc: Allow the skipHeader attribute on enumsPaul Elder
Currently, enums that are passed between pipeline handlers and their IPA must be defined in a mojom file. However, there is a use case for enum/flags to be defined in a C++ header, such that the enum can be used in a component other than the pipeline handler and its IPA.

Add Flags<E> as a supported type in the IPA interface. It is used in mojom with the [flags] attribute. Any field or parameter type E that is prefixed with the [flags] attribute will direct the code generator to generate the type name "Flags<E>" and appropriate serialization/deserialization code for Flags<E> instead of for E. It is usable and has been tested in struct members, function input and output parameters, and Signal parameters. This does not add support for returning Flags as direct return values.

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.

The ControlList::set() function overload used for array controls constructs a Span from an initializer list. It doesn't specify the Span size explicitly, which results in a dynamic extent Span being constructed. That causes a compilation failure for fixed-size array controls, as they are defined as Control<T> with T being a fixed-extent Span, and conversion from a dynamic-extent to fixed-extent Span when calling ControlValue::set() can't be implicit. Fix this by constructing the Span using the size of the control, which resolves to a fixed-extent and dynamic-extent Span for fixed-size and dynamic-size array controls respectively. The ControlList::set() function that takes an initializer list can then be used for fixed-size array controls.
