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)
