These two changes mostly finish the C++20 migration by switching to `std::span`. This has so far been postponed because gcc 9 does not support `std::span`, but gcc 9 has just been dropped from CI. Some points: 0. patchwork did not pick up the "Use `std::span`" commit when it was sent the last time: https://patchwork.libcamera.org/cover/26313/ 1. should the minimum compiler versions be raised? 2. notably, this also affects the public interfaces (e.g. Camera::generateConfiguration(), Control<>) Barnabás Pőcze (2): treewide: Use `std::span` libcamera: base: span: Deprecate it Documentation/guides/pipeline-handler.rst | 4 +- include/libcamera/base/file.h | 10 ++-- include/libcamera/base/span.h | 16 +++---- include/libcamera/base/thread.h | 4 +- include/libcamera/camera.h | 6 +-- include/libcamera/controls.h | 22 ++++++--- include/libcamera/framebuffer.h | 10 ++-- .../libcamera/internal/byte_stream_buffer.h | 6 +-- include/libcamera/internal/camera_sensor.h | 6 +-- .../converter/converter_dw100_vertexmap.h | 5 +- include/libcamera/internal/egl.h | 14 +++--- include/libcamera/internal/framebuffer.h | 4 +- .../libcamera/internal/mapped_framebuffer.h | 4 +- include/libcamera/internal/matrix.h | 26 +++++------ include/libcamera/internal/pipeline_handler.h | 2 +- include/libcamera/internal/process.h | 6 +-- include/libcamera/internal/pub_key.h | 7 ++- .../libcamera/internal/shared_mem_object.h | 6 +-- include/libcamera/internal/v4l2_device.h | 6 +-- include/libcamera/internal/vector.h | 4 +- src/android/camera_buffer.h | 11 +++-- src/android/camera_capabilities.cpp | 3 +- src/android/camera_request.cpp | 4 +- src/android/jpeg/encoder.h | 4 +- src/android/jpeg/encoder_jea.cpp | 2 +- src/android/jpeg/encoder_jea.h | 2 +- src/android/jpeg/encoder_libjpeg.cpp | 10 ++-- src/android/jpeg/encoder_libjpeg.h | 12 ++--- src/android/jpeg/exif.cpp | 2 +- src/android/jpeg/exif.h | 7 ++- src/android/jpeg/post_processor_jpeg.cpp | 2 +- src/android/mm/cros_camera_buffer.cpp | 4 +- .../mm/cros_frame_buffer_allocator.cpp | 2 +- src/android/mm/generic_camera_buffer.cpp | 4 +- .../mm/generic_frame_buffer_allocator.cpp | 2 +- src/apps/cam/capture_script.cpp | 12 ++--- src/apps/cam/drm.cpp | 6 +-- src/apps/cam/drm.h | 4 +- src/apps/cam/file_sink.cpp | 2 +- src/apps/cam/sdl_sink.cpp | 4 +- src/apps/cam/sdl_texture.h | 4 +- src/apps/cam/sdl_texture_1plane.cpp | 2 +- src/apps/cam/sdl_texture_1plane.h | 2 +- src/apps/cam/sdl_texture_mjpg.cpp | 4 +- src/apps/cam/sdl_texture_mjpg.h | 4 +- src/apps/cam/sdl_texture_yuv.cpp | 2 +- src/apps/cam/sdl_texture_yuv.h | 2 +- src/apps/common/dng_writer.cpp | 4 +- src/apps/common/image.cpp | 6 +-- src/apps/common/image.h | 10 ++-- src/apps/common/ppm_writer.cpp | 2 +- src/apps/common/ppm_writer.h | 4 +- src/apps/ipa-verify/main.cpp | 4 +- src/apps/lc-compliance/helpers/capture.cpp | 2 +- src/apps/lc-compliance/helpers/capture.h | 3 +- src/gstreamer/gstlibcamera-controls.cpp.in | 4 +- src/gstreamer/gstlibcamera-utils.cpp | 20 ++++---- src/ipa/ipu3/algorithms/af.cpp | 6 +-- src/ipa/ipu3/algorithms/af.h | 2 +- src/ipa/ipu3/algorithms/agc.cpp | 2 +- src/ipa/ipu3/ipu3.cpp | 8 ++-- src/ipa/libipa/awb.h | 2 +- src/ipa/libipa/awb_bayes.cpp | 2 +- src/ipa/libipa/awb_bayes.h | 4 +- src/ipa/libipa/exposure_mode_helper.cpp | 2 +- src/ipa/libipa/exposure_mode_helper.h | 4 +- src/ipa/libipa/histogram.cpp | 4 +- src/ipa/libipa/histogram.h | 8 ++-- src/ipa/libipa/lsc_base.h | 2 -
