2024-05-08libcamera: Drop file name from header comment blocksLaurent Pinchart
Source files in libcamera start by a comment block header, which includes the file name and a one-line description of the file contents. While the latter is useful to get a quick overview of the file contents at a glance, the former is mostly a source of inconvenience. The name in the comments can easily get out of sync with the file name when files are renamed, and copy & paste during development have often lead to incorrect names being used to start with. Readers of the source code are expected to know which file they're looking it. Drop the file name from the header comment block. The change was generated with the following script: ---------------------------------------- dirs="include/libcamera src test utils" declare -rA patterns=( ['c']=' \* ' ['cpp']=' \* ' ['h']=' \* ' ['py']='# ' ['sh']='# ' ) for ext in ${!patterns[@]} ; do files=$(for dir in $dirs ; do find $dir -name "*.${ext}" ; done) pattern=${patterns[${ext}]} for file in $files ; do name=$(basename ${file}) sed -i "s/^\(${pattern}\)${name} - /\1/" "$file" done done ---------------------------------------- This misses several files that are out of sync with the comment block header. Those will be addressed separately and manually. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Daniel Scally <dan.scally@ideasonboard.com>
2022-08-16libcamera: base: Make message.h and mutex.h privateLaurent Pinchart
The message.h and mutex.h headers are not used in the libcamera public API. Make them private to avoid there usage in applications, and to prevent having to maintain them with a stable ABI. As mutex.h is used by libcamerasrc, the GStreamer element must switch from the libcamera_public to the libcamera_private dependency.

2021-12-01libcamera: base: Add mutex classes with thread safety annotationsHirokazu Honda
This replaces Mutex and MutexLocker with our own defined classes. The classes are annotated by clang thread safety annotations. So we can add annotation to code where the classes are used. v4l2 code needs to be annotated, which violates Mutex capability.
