From 0f547931397f1d2de871dc4a53a66b5c4cd250dd Mon Sep 17 00:00:00 2001 From: Claude Date: Sun, 24 May 2026 15:12:49 +0000 Subject: [PATCH 1/3] Fix critical bugs, security vulnerability, and code quality issues MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Critical: - FloatValidator now rejects integers (isinstance check replaces float() cast) - IntegerValidator now rejects strings and bools (strict isinstance check) - ForeignListProperty.get_db_value() no longer crashes — initialize return_type - ValleyDecoder now requires an allowed_types allowlist to prevent arbitrary class instantiation from untrusted JSON Major: - Schema class gets _create_error_dict = True default; validate() no longer AttributeErrors - BaseProperty.validate() and get_db_value() use `is None` instead of falsy check (fixes 0/False/[]/'' being treated as missing) - DateValidator/DateTimeValidator raise on invalid strings immediately instead of silent pass - ForeignProperty/ForeignListProperty use to_dict() instead of ._data directly - FloatProperty now wires up min_value/max_value kwargs like IntegerProperty Minor/Nit: - Remove `import time`; use datetime.date.fromisoformat() - BooleanProperty.get_default_value() returns None when unset - Replace `type(None)` antipattern with `is not None` - Add type hints and docstrings to DateValidator/DateTimeValidator - Use f-strings consistently in date validators - Fix __unicode__ -> __str__ in example schemas - ChoiceValidator handles non-dict choices safely - Guard inspect.getmodule() None return in ValleyEncoder - Remove collections.OrderedDict from declarative.__prepare__ (redundant in 3.7+) - Fix octal escape typo in EmailValidator regex (\001-011 -> \001-\011) - ForeignListProperty.get_validators() uses append() instead of insert(len()) - Stale StringProperty docstring "CharProperty" corrected - Add PEP 8 blank line between DateTimeValidator and BooleanValidator - Clarify requirements.txt as Poetry-managed https://claude.ai/code/session_01JGryFUpmEmKYAVhqSrkV8R --- requirements.txt | 2 +- valley/declarative.py | 7 +-- valley/properties.py | 39 +++++++------ valley/schema.py | 1 + valley/tests/examples/example_schemas.py | 2 +- valley/tests/test_declarative.py | 5 +- valley/tests/test_utils.py | 13 ++++- valley/utils/json_utils.py | 27 +++++++-- valley/validators.py | 70 ++++++++++-------------- 9 files changed, 94 insertions(+), 72 deletions(-) diff --git a/requirements.txt b/requirements.txt index 8b13789..2b4395f 100644 --- a/requirements.txt +++ b/requirements.txt @@ -1 +1 @@ - +# Dependencies are managed via Poetry.
