Add comprehensive test coverage for union types with None to prevent
regression of the issubclass() TypeError that was occurring when
checking if None is in a union type.
Motivation: A warning should encourage consistent usage of inventory.machines setting targetHost inside the machine should be considered a custom override
Changing the warning strings to avoid the term 'nix'/'json' both inventory and nixos machines are nix features
- Remove _serialized field from vars interface to prevent serialization
errors with throwing passBackend field
- Implement direct selection of generator fields using multi-select syntax
- Refactor vars_generators() to use new Generator.from_flake() method that
selects only safe fields (avoiding non-serializable values)
- Remove unused legacy methods: Generator.from_json(), Var.from_json(),
Prompt.from_json()
- Update precaching to match new selection approach
This fixes the serialization errors that were preventing vars from working
with the new password-store implementation by avoiding the problematic
_serialized field entirely.
When using multiselect with outPath like {outPath,?meta}, nix evaluation
collapses the attrset to just the outPath string, breaking further selection.
Add validation during selector parsing to catch this and provide a clear error.
- Remove deployment.json file generation from outputs.nix
- Add throw for deprecated deployment.file usage with upgrade instructions
- Remove vars data from deployment.data
- Update Machine class to use direct select() calls instead of deployment property
- Update all deployment property accesses to use direct selectors
- Add precaching for frequently accessed values in update.py:
- Module paths for facts and vars
- Deployment settings (requireExplicitUpdate, nixosMobileWorkaround)
- Services and generators data
- Secret upload locations
- This removes unnecessary JSON serialization and makes the code more composable
- Remove nix(), eval_nix(), and build_nix() methods from Machine class
- Add select() method that handles machine-specific attribute prefixes
- Update all usages to use machine.select() directly
- Handle Path conversion and tmp_store logic at call sites
- This simplifies the Machine API and prepares for deployment.json removal
