From bedac77e9348e7a54c0ec364fb61df90cd893972 Mon Sep 17 00:00:00 2001 From: Brett Holman Date: Mon, 6 Dec 2021 15:27:12 -0700 Subject: Add Strict Metaschema Validation (#1101) Improve schema validation. This adds strict validation of config module definitions at testing time, with plumbing included for future runtime validation. This eliminates a class of bugs resulting from schemas that have definitions that are incorrect, but get interpreted by jsonschema as "additionalProperties" that are therefore ignored. - Add strict meta-schema for jsonschema unit test validation - Separate schema from module metadata structure - Improve type annotations for various functions and data types Cleanup: - Remove unused jsonschema "required" elements - Eliminate manual memoization in schema.py:get_schema(), reference module.__doc__ directly --- cloudinit/util.py | 17 ++++++++++++++++- 1 file changed, 16 insertions(+), 1 deletion(-) (limited to 'cloudinit/util.py') diff --git a/cloudinit/util.py b/cloudinit/util.py index 2045a6ab..1b462a38 100644 --- a/cloudinit/util.py +++ b/cloudinit/util.py @@ -347,7 +347,7 @@ def extract_usergroup(ug_pair): return (u, g) -def find_modules(root_dir): +def find_modules(root_dir) -> dict: entries = dict() for fname in glob.glob(os.path.join(root_dir, "*.py")): if not os.path.isfile(fname): @@ -2751,4 +2751,19 @@ def get_proc_ppid(pid): ppid = int(parts[3]) return ppid + +def error(msg, rc=1, fmt='Error:\n{}', sys_exit=False): + """ + Print error to stderr and return or exit + + @param msg: message to print + @param rc: return code (default: 1) + @param fmt: format string for putting message in (default: 'Error:\n {}') + @param sys_exit: exit when called (default: false) + """ + print(fmt.format(msg), file=sys.stderr) + if sys_exit: + sys.exit(rc) + return rc + # vi: ts=4 expandtab -- cgit v1.2.3
