2022-10-07libcamera: pipeline_handler: Implement factories through class templatesLaurent Pinchart
The REGISTER_PIPELINE_HANDLER() macro defines a class type that inherits from the PipelineHandlerFactory class, and implements a constructor and a createInstance() function. Replace the code generation through macro with the C++ equivalent, a class template, as done in libipa with the Algorithm and CameraSensorHelper factories.

Avoid naked pointer with memory allocation by returning a unique_ptr from PipelineHandlerFactory::createInstance(), in order to increase memory allocation safety. This allows iterating over factories in the CameraManager and unit tests using const pointers.

2022-03-25libcamera: base: timer: Drop start() overload with int argumentLaurent Pinchart
The start(unsigned int msec) overload is error-prone, as the argument unit can easily be mistaken in callers. Drop it and update all callers to use the start(std::chrono::milliseconds) overload instead. The callers now need to use std::chrono_literals. The using statement could be added to timer.h for convenience, but "using" is discouraged in header files to avoid namespace pollution. Update the callers instead, and while at it, sort the "using" statements alphabetically in tests.

2021-09-02libcamera: Drop emitter object pointer from signal argumentsLaurent Pinchart
Many signals used in internal and public APIs carry the emitter pointer as a signal argument. This was done to allow slots connected to multiple signal instances to differentiate between emitters. While starting from a good intention of facilitating the implementation of slots, it turned out to be a bad API design as the signal isn't meant to know what it will be connected to, and thus shouldn't carry parameters that are solely meant to support a use case specific to the connected slot. These pointers turn out to be unused in all slots but one. In the only case where it is needed, it can be obtained by wrapping the slot in a lambda function when connecting the signal. Do so, and drop the emitter pointer from all signals. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Umang Jain <umang.jain@ideasonboard.com>
2021-09-02libcamera: Don't use emitter object pointer argument to slotLaurent Pinchart
In many cases, the emitter object passed as a pointer from signals to slots is also available as a class member. Use the class member when this occurs, to prepare for removal of the emitter object pointer from signals. In test/event.cpp, this additionally requires moving the EventNotifier to a class member.

This requires files within libcamera to include them with #include <ipa/foo.h> while a third party IPA would need to use #include <libcamera/ipa/foo.h> Not only is this inconsistent, it can create issues later if IPA headers need to include each other, as the first form of include directive wouldn't be valid once the headers are installed.

2020-05-16libcamera: Move internal headers to include/libcamera/internal/Laurent Pinchart
The libcamera internal headers are located in src/libcamera/include/. The directory is added to the compiler headers search path with a meson include_directories() directive, and internal headers are included with (e.g. for the internal semaphore.h header) #include "semaphore.h" All was well, until libcxx decided to implement the C++20 synchronization library. The __threading_support header gained a #include <semaphore.h> to include the pthread's semaphore support. As include_directories() adds src/libcamera/include/ to the compiler search path with -I, the internal semaphore.h is included instead of the pthread version. Needless to say, the compiler isn't happy. Three options have been considered to fix this issue: - Use -iquote instead of -I. The -iquote option instructs gcc to only consider the header search path for headers included with the "" version. Meson unfortunately doesn't support this option. - Rename the internal semaphore.h header. This was deemed to be the beginning of a long whack-a-mole game, where namespace clashes with system libraries would appear over time (possibly dependent on particular system configurations) and would need to be constantly fixed. - Move the internal headers to another directory to create a unique namespace through path components. This causes lots of churn in all the existing source files through the all project. The first option would be best, but isn't available to us due to missing support in meson. Even if -iquote support was added, we would need to fix the problem before a new version of meson containing the required support would be released. The third option is thus the only practical solution available. Bite the bullet, and do it, moving headers to include/libcamera/internal/.
