2024-10-18libcamera: tracepoints: Fix copyright year for reproducible buildsBernhard M. Wiedemann
The tracepoints.h file is generated from the tracepoints.h.in template by the gen-tp-header.py script. The template contains a {{year}} placeholder for the copyright year, which the script fills with the current year. This breaks reproducible builds with at least the openSUSE debugsource package. As the gen-tp-header.py script doesn't add any copyrightable contents to the tracepoints.h file, fix this by replacing the {{year}} placeholder with the year of the last copyright-worthy change to tracepoints.h.in.

2024-08-16meson: utils: Provide environment for Python scriptsLaurent Pinchart
Python scripts run as part of the build process need to take a few actions specific to the environment in which they operate. One of those is disabling the Python bytecode cache, to avoid writing .pyc files to the source tree. This is done manually in the IPC generate.py and parser.py scripts. The current implementation is not ideal because it hardcodes in the scripts information related to the environment in which they operate. As those scripts are part of libcamera this is more of a theoretical issue than a practical one. A second issue is that future Python scripts will need to duplicate similar mechanisms, resulting in a higher maintenance burden. Address the issue with a different approach, by creating a meson environment for the Python scripts, and passing it to the custom_target() functions. The environment only disables the bytecode cache for now. The diffstat shows an increase in code size. This is expected to be offset by usage of the environment for more Python scripts, as well as support of more variables in the environment.

When running checkstyle.py in a pre-commit hook, there is either no commit message at all (when committing staged changes as a new commit), or the commit message comes from a previous commit being amended. In either case, there's no new commit message yet, and thus nothing to validate for the title and trailers checkers.

2024-08-12utils: checkstyle.py: Rework commit message parsingLaurent Pinchart
When parsing commit messages, the Commit class tries to optimize the process by invoking git-show once only, extracting both the commit author, title and modified files in one go. As a result, the derived Amendment class needs to implement the commit parsing separately, as the modified files need to be extracted differently for amendments (and the commit ID also needs to be retrieved differently). Furthermore, because of the list of named files, extracting the trailers needs to invoke git-show separately. Improve the situation by reworking the commit message parsing in three steps. In the first step, use git-show to extract the commit ID, author, title and body. In the second step, invoke git-interpret-trailers to extract the trailers from the body that was previously extracted. The third and final step extracts the list of modified files, using different methods for regular commits and amendments. This allows sharing code for the first two steps between the Commit and Amendment classes, making the code simpler. The Commit class still invokes git three times, while the Amendment class runs it three times instead of four, improving performance slightly.

This prevents trailers from being located when the patch contains a local changelog. There is unfortuantely no 'no-no-divider' option to the trailers format specifier.

2024-07-25utils: gen-version: Use posix compliant dateZach DeCook
The version string of libcamera is presently appended with a date/time argument in the case of a dirty tree to show further detail of when it was built. This string is generated with the iso-8601 parameter to 'date' and produces a date string in the form: "2024-06-17T22:15:30+01:00" Strict posix shells or implementations of 'date' which may be optimised for size such as the one provided by busybox or Alpine Linux may not support the '--iso-8601' flag. To support builds on those platforms, use a direct POSIX-compliant date-format string instead matching as closely as possible to the iso-8601 definition. An exact match is not possible with those restrictions so 'date %Y-%m-%dT%H:%M:%S%Z' is used which produces 2024-06-17T22:15:30BST. The use of the human readable timezone identifier provides a friendlier output for the string than a timezone offset at the expense of being less sortable in the exceptionally low risk and unlikely event of two custom builds being compared at the same time of different timezones.
