oso 0.5.2

New features

Support for constructors with both positional and keyword arguments ( #405)

• In languages that support both positional and keyword arguments (currently Python and Ruby), Oso now supports registering classes with constructors that use both.

• The syntax for calling a constructor with mixed arguments from an Oso policy is:

  new MyClass(1, 2, foo: 3)
  

• As with Python and Ruby, positional arguments must come before keyword arguments.

• For more, see documentation for the new operator.

Other bugs & improvements

• The Node.js library will now throw an InvalidConstructorError when attempting to register a non-constructable object via registerClass. ( #392)
• Rule indexing performance improvements. ( #409)
• Standardize handling of ±∞ and NaN across all language libraries. ( #410)
• Better warnings for unknown specializers that are similar to built-in types. ( #403)
• Fix an issue with readline’s calculation of the cursor position in the Python REPL on Linux. ( #397)
