Make validate-json fail on invalid input.
GtsJsonValidator.validate() can return result.ok == False, but main writes the report and returns normally. Both CLI entrypoints then exit with status 0, so CI cannot reject invalid JSON from the command status. Raise SystemExit(1) after writing the JSON when not result.ok, and update tests/test_json_validation.py:73 to expect it.

🌐 Web query:
Python os.walk followlinks=True infinite recursion symlink loop documentation
💡 Result:
The Python os.walk() function does not automatically handle or prevent infinite recursion when followlinks=True is enabled [1][2][3]. Because os.walk() does not track the directories it has already visited, it will follow symbolic links that point to parent directories (or other directories already in the current traversal path), resulting in an infinite loop [1][2][3]. To prevent infinite recursion when using followlinks=True, you must manually keep track of the directories visited [1]. A reliable way to do this is to store the device ID and inode number of each directory you visit in a set [1]. The following example demonstrates this approach: import os visited_dirs = set for dirpath, dirnames, filenames in os.walk('.', followlinks=True): # Get unique identifier for the current directory st = os.stat(dirpath) dirkey = (st.st_dev, st.st_ino) # If already visited, remove from dirnames to prune the search if dirkey in visited_dirs: dirnames[:] = [] continue visited_dirs.add(dirkey) # Continue processing... It is important to note that even when followlinks=False (the default), os.walk() still identifies symbolic links to directories and includes them in the dirnames list (though it does not descend into them) [4][5][6]. This behavior is considered unintuitive by some users [7], but it is the long-standing design of the function [6]. In recent Python versions (3.12+), an internal mechanism os._walk_symlinks_as_files was introduced to allow for more granular control over this behavior, which is now utilized by pathlib.Path.walk() to treat symlinks as files rather than directories [7][5].

Guard the directory walk against symlink cycles.
os.walk(..., followlinks=True) follows directory symlinks and does not track visited directories. A symlink to an ancestor can make validate-json recurse indefinitely.

Narrow the GTS-relatedness heuristic.
_is_gts_related currently matches "gts." in every nested string. A normal JSON document can therefore enter registration and receive "GTS-related document has no registrable GTS ID", which makes result.ok false.
Base relatedness on the configured identifier fields. Validate candidate values with GtsID.is_valid. For schemas, use a valid $id, not a $schema URL. For instances, accept valid entity IDs and valid configured type fields. Preserve type-only instances with a valid type ID and no entity ID.

Skip instances that are not registered in GtsStore.
When _register_gts_entities finds a duplicate key, it does not register that entity. _validate_instances still calls store.validate_instance(key), which retrieves the first entity for that key. Any failure is then reported with the duplicate entity's file and index. Add the same identity check used by _validate_schemas.

Batch validation is useful, but I suggest addressing these points before merging:
The Python implementation already prunes excluded directories correctly, performs actual JSON Schema meta-validation, uses named constructor arguments, and includes three tests for the new path. Keep those improvements and extend coverage for malformed IDs, incidental GTS mentions, duplicates, schema-ID URI rules, traversal failures, and exit status. Reviewed against |
