This script checks for inconsistencies on symbols declared in Config.in and used in .mk files. Currently it checks only symbols following the pattern BR2_\w+ . The script first gets the list of all files in the repository (using git ls-files like 'make check-flake8' already do). Then it parses all relevant files, searching for symbol definitions and usages, and add entries into a database. At the end, the database is searched for inconsistencies: - symbol that is part of "choice" and is referenced with "select"; - legacy symbol being referenced in packages; - legacy symbol being redefined in packages; - symbol referenced but not defined; - symbol defined but not referenced; - legacy symbol that has a Note stating it is referenced by a package (for legacy handling) but is referenced in the package without a comment "# legacy"; - legacy symbol that has a Note stating it is referenced by a package but it is not actually referenced. There is also a debug parameter --search that dumps any filename or symbol entries from the database that matches a regexp. Sample usages: $ utils/check-symbols $ utils/docker-run utils/check-symbols $ utils/check-symbols --search 'GETTEXT\b|\/openssl' At same time the script is created: - add unit tests for it, they can be run using: utils/docker-run python3 -m pytest -v utils/checksymbolslib/ - add two more GitLab CI jobs: check-symbols (to check current tree using the script) and check-check-symbols (to check the script against its unit tests) Cc: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Signed-off-by: Ricardo Martincoski <ricardo.martincoski@gmail.com> [Peter: print warnings to stderr, rename change_current_dir() to change_to_top_dir()] Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
