Privacy Fixer System
====================

This document provides technical details about the privacy fixer implementation for automatically renaming functions with privacy violations. The system handles both W9004 violations (functions that should be private) and W9005 violations (private functions that should be public).

Overview
--------

The privacy fixer system implements automatic function renaming with a **safety-first design philosophy**. It identifies privacy violations through bidirectional analysis:

- **W9004 Detection**: Public functions that should be private (add underscore prefix)
- **W9005 Detection**: Private functions that should be public (remove underscore prefix)

The system can automatically apply these renames, but only when it can guarantee the safety of the operation.

**Core Principle**: Better to skip a function than to rename it incorrectly.

The system operates in four phases:

1. **Detection Phase**: Identify privacy violations using W9004 and W9005 analysis
2. **Analysis Phase**: Find all references to functions requiring privacy changes
3. **Safety Validation Phase**: Ensure renaming can be done safely without breaking code
4. **Renaming Phase**: Apply the actual renames and update all references
5. **Optional Sorting Phase**: Automatically resort functions after privacy fixes with ``--auto-sort``

Design Philosophy
-----------------

Safety-First Architecture
~~~~~~~~~~~~~~~~~~~~~~~~~

The implementation prioritizes safety over completeness:

- **Conservative Approach**: Only rename functions where ALL references can be found and validated
- **Comprehensive Analysis**: Analyze all possible reference types (calls, assignments, decorators, etc.)
- **Validation Guards**: Multiple safety checks prevent unsafe operations
- **Dry-Run Support**: Preview changes before applying them
- **Backup Creation**: Automatic backup files for safety

**Trade-off**: Some valid renamings may be skipped to ensure zero false positives.

User Control and Transparency
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

- **Explicit Opt-in**: Users must explicitly request privacy fixes (``--fix-privacy`` flag)
- **Clear Reporting**: Detailed reports explain what can/cannot be renamed and why
- **Incremental Processing**: Users can apply fixes file-by-file for better control
- **Rollback Support**: Backup files allow easy rollback of changes

Architecture Overview
---------------------

Core Components
~~~~~~~~~~~~~~~

The privacy fixer consists of three main classes:

.. code-block:: text

    ┌─────────────────┐    ┌──────────────────┐    ┌──────────────────┐
    │ FunctionReference │    │  RenameCandidate │    │   PrivacyFixer   │
    │                 │    │                  │    │                  │
    │ - AST node      │    │ - Function node  │    │ - Analysis logic │
    │ - Location info │    │ - Old/new names  │    │ - Safety checks  │
    │ - Context type  │    │ - References     │    │ - Apply renames  │
    │                 │    │ - Safety status  │    │ - Generate report│
    └─────────────────┘    └──────────────────┘    └──────────────────┘

**Data Flow**:

.. code-block:: text

    Module AST -> Find References -> Safety Validation -> Rename Application
                       |                       |                      |
                       v                       v                      v
              FunctionReference    RenameCandidate      Updated Source

Integration Points
~~~~~~~~~~~~~~~~~~

The privacy fixer integrates with existing system components:

- **W9004 Detection**: Uses existing ``should_function_be_private()`` logic from ``utils.py``
- **AST Analysis**: Leverages same ``astroid`` infrastructure as the PyLint plugin
- **CLI Integration**: Extends existing CLI with ``--fix-privacy`` argument
- **Configuration**: Respects existing ``public-api-patterns`` configuration

Implementation Details
----------------------

1. FunctionReference Class
~~~~~~~~~~~~~~~~~~~~~~~~~~

Represents a single reference to a function within a module.

.. code-block:: python

    class FunctionReference(NamedTuple):
        """Represents a reference to a function within a module."""

        node: nodes.NodeNG      # AST node containing the reference
        line: int               # Line number of the reference
        col: int                # Column offset of the reference
        context: str            # Type of reference

**Reference Context Types**:

- ``"call"``: Function call (``function_name()``)
- ``"assignment"``: Variable assignment (``var = function_name``)
- ``"decorator"``: Decorator usage (``@function_name``)
- ``"reference"``: Generic name reference

**Usage Example**:

.. code-block:: python

    # For code: result = helper_function()
    ref = FunctionReference(
        node=call_node,
        line=42,
        col=12,
        context="call"
    )

2. RenameCandidate Class
~~~~~~~~~~~~~~~~~~~~~~~~

Represents a function that potentially can be renamed to private.

.. code-block:: python

    class RenameCandidate(NamedTuple):
        """Represents a function that can be safely renamed."""

        function_node: nodes.FunctionDef    # Original function AST node
        old_name: str                       # Current function name
        new_name: str                       # Proposed private name
        references: List[FunctionReference] # All found references
        is_safe: bool                      # Safety validation result
        safety_issues: List[str]           # Reasons if unsafe

**Lifecycle**:

1. **Creation**: Built from W9004 detection results
2. **Reference Analysis**: Populated with all found references
3. **Safety Validation**: ``is_safe`` and ``safety_issues`` determined
4. **Processing**: Either applied (if safe) or skipped (if unsafe)

**Status Examples**:

.. code-block:: python

    # Safe to rename
    safe_candidate = RenameCandidate(
        function_node=func_ast,
        old_name="helper_function",
        new_name="_helper_function",
        references=[ref1, ref2],
        is_safe=True,
        safety_issues=[]
    )

    # Unsafe to rename
    unsafe_candidate = RenameCandidate(
        function_node=func_ast,
        old_name="complex_function",
        new_name="_complex_function",
        references=[ref1],
        is_safe=False,
        safety_issues=["Function name found in string literals"]
    )

3. PrivacyFixer Class
~~~~~~~~~~~~~~~~~~~~~

Main orchestration class that coordinates the privacy fixing process.

.. code-block:: python

    class PrivacyFixer:
        """Handles automatic renaming of functions that should be private."""

        def __init__(self, dry_run: bool = False, backup: bool = True):
            self.dry_run = dry_run      # Preview mode
            self.backup = backup        # Create .bak files

**Key Methods**:

**generate_report()** - *✅ IMPLEMENTED*
    Generate human-readable reports of rename operations and status.

Reference Detection Algorithm
-----------------------------

The reference detection system uses recursive AST traversal to find all possible references to a target function.

AST Traversal Strategy
~~~~~~~~~~~~~~~~~~~~~~

.. code-block:: python

    def find_function_references(self, function_name: str, module_ast: nodes.Module):
        """Find all references using recursive AST traversal."""

        references = []
        decorator_nodes = set()  # Prevent double-counting

        def _check_node(node):
            # 1. Check for function calls
            # 2. Check for decorator usage
            # 3. Check for name references
            # 4. Recursively process children
            pass

        _check_node(module_ast)
        return references

**Reference Type Detection**:

1. **Function Calls**:

   .. code-block:: python

       # Detects: function_name()
       if isinstance(node, nodes.Call):
           if isinstance(node.func, nodes.Name) and node.func.name == function_name:
               # Found function call
               pass

2. **Decorator References**:

   .. code-block:: python

       # Detects: @function_name
       if hasattr(node, 'decorators') and node.decorators:
           for decorator in node.decorators.nodes:
               if isinstance(decorator, nodes.Name) and decorator.name == function_name:
                   # Found decorator usage
                   pass

3. **Assignment References**:

   .. code-block:: python

       # Detects: var = function_name
       if isinstance(node, nodes.Name) and node.name == function_name:
           if isinstance(node.parent, nodes.Assign):
               # Found assignment reference
               pass

**Duplicate Prevention**:

The algorithm prevents double-counting of decorator nodes that appear both as decorators and as name references during AST traversal:

.. code-block:: python

    decorator_nodes = set()

    # Mark decorator nodes to prevent double-counting
    decorator_nodes.add(id(decorator))

    # Skip if already processed as decorator
    if id(node) in decorator_nodes:
        pass

**Edge Cases Handled**:

- **Function Definitions**: Skips the function definition itself
- **Call Node Functions**: Avoids double-counting ``func`` in ``func()``
- **Complex Decorators**: Handles ``@module.decorator`` patterns
- **Nested References**: Recursively finds references in nested scopes

Safety Validation System
-------------------------

The safety validation system implements multiple conservative checks to ensure renaming operations won't break code.

Validation Categories
~~~~~~~~~~~~~~~~~~~~~

1. **Name Conflict Detection**
   *Status: ✅ Fully implemented with module AST scanning*

   Checks if the proposed private name already exists:

   .. code-block:: python

       def _has_name_conflict(self, candidate: RenameCandidate) -> bool:
           # Check module AST for existing function with new_name
           # Conservative approach: assumes conflict if check fails
           return False  # or True on exception

2. **Dynamic Reference Detection**
   *Status: ✅ Framework implemented with conservative detection*

   Identifies dynamic references that can't be safely renamed:

   .. code-block:: python

       # These patterns make renaming unsafe:
       getattr(obj, "function_name")         # Dynamic attribute access
       hasattr(obj, "function_name")         # Dynamic attribute check
       setattr(obj, "function_name", value)  # Dynamic attribute setting
       eval("function_name()")               # Code evaluation
       exec("result = function_name()")      # Code execution

3. **String Literal Detection**
   *Status: ✅ Framework implemented with conservative validation*

   Finds function names embedded in string literals:

   .. code-block:: python

       # These make renaming potentially unsafe:
       sql_query = "SELECT * FROM helper_function_results"
       log_message = f"Calling helper_function with args {args}"
       documentation = """The helper_function does..."""

4. **Reference Context Validation**
   *Status: ✅ Implemented*

   Ensures all references are in contexts we can handle:

   .. code-block:: python

       def validate_contexts(candidate):
           safe_contexts = {"call", "assignment", "decorator", "reference"}
           issues = []

           # Any reference in an unknown context is considered unsafe
           for ref in candidate.references:
               if ref.context not in safe_contexts:
                   issues.append(f"Unsafe context: {ref.context}")

           return len(issues) == 0

Conservative Safety Design
~~~~~~~~~~~~~~~~~~~~~~~~~~

**Default to Unsafe**: When validation cannot be completed, the system assumes unsafe conditions.

.. code-block:: python

    def _has_name_conflict(self, candidate: RenameCandidate) -> bool:
        try:
            # Attempt to check for conflicts
            return self._check_module_for_conflicts(candidate)
        except Exception:
            return True  # Conservative: assume conflict exists

**Multiple Validation Layers**: All checks must pass for a rename to be considered safe:

.. code-block:: python

    def is_safe_to_rename(self, candidate: RenameCandidate) -> Tuple[bool, List[str]]:
        issues = []

        if self._has_name_conflict(candidate):
            issues.append("Name conflict detected")

        if self._has_dynamic_references(candidate):
            issues.append("Dynamic references found")

        if self._has_string_references(candidate):
            issues.append("String references found")

        # All checks must pass
        return len(issues) == 0, issues

Integration with Privacy Detection System
------------------------------------------

The privacy fixer builds on the comprehensive privacy detection system from ``utils.py`` which includes both W9004 and W9005 detection.

Detection Integration
~~~~~~~~~~~~~~~~~~~~~

**Bidirectional Detection Logic** (in ``utils.py``):

.. code-block:: python

    def should_function_be_private(
        func: nodes.FunctionDef,
        module_path: Path,
        project_root: Path,
        public_patterns: Optional[Set[str]] = None,
    ) -> bool:
        """Detect if a public function should be private based on import analysis."""

    def should_function_be_public(
        func: nodes.FunctionDef,
        module_path: Path,
        project_root: Path,
    ) -> bool:
        """Detect if a private function should be public based on external usage."""

**Privacy Fixer Integration**:

.. code-block:: python

    def analyze_module(self, module_path: Path, project_root: Path,
                      public_patterns: Optional[Set[str]] = None) -> List[RenameCandidate]:
        """Identify privacy violations using W9004/W9005 detection."""
        # Implementation:
        # 1. Parse module AST
        # 2. Extract all functions
        # 3. Use should_function_be_private() for W9004 candidates
        # 4. Use should_function_be_public() for W9005 candidates
        # 5. Build RenameCandidate objects
        # 6. Run reference detection and safety validation

**Configuration Consistency**:

Both systems respect the same configuration options:
- ``public-api-patterns``: Functions to treat as public API
- ``enable-privacy-detection``: Whether to perform privacy analysis

CLI Integration
---------------

The privacy fixer is fully integrated with the existing CLI system through comprehensive arguments.

Implemented CLI Arguments
~~~~~~~~~~~~~~~~~~~~~~~~~

**--fix-privacy**
    *Status: ✅ IMPLEMENTED*

    Enable automatic privacy fixing mode:

    .. code-block:: bash

        pylint-sort-functions --fix-privacy src/

    **Behavior**:
    - Identifies W9004 violations (functions that should be private)
    - Identifies W9005 violations (private functions that should be public)
    - Performs comprehensive safety analysis
    - Applies safe renames automatically
    - Reports unsafe cases for manual review
    - Creates backup files for safety

**--privacy-dry-run**
    *Status: ✅ IMPLEMENTED*

    Preview privacy fixes without applying them:

    .. code-block:: bash

        pylint-sort-functions --fix-privacy --privacy-dry-run src/

**--auto-sort**
    *Status: ✅ IMPLEMENTED*

    Automatically resort functions after privacy fixes:

    .. code-block:: bash

        pylint-sort-functions --fix-privacy --auto-sort src/

    **Output Example**:

    .. code-block:: text

        Privacy Fix Analysis:

        ✅ Can safely rename 2 functions:
          • helper_function → _helper_function (3 references)
          • utility_func → _utility_func (1 reference)

        ⚠️  Cannot safely rename 1 function:
          • complex_helper: Function name found in string literals

**Integration with Existing Options**:

The privacy fixer respects existing configuration:

.. code-block:: bash

    # Respect public API patterns
    pylint-sort-functions --fix-privacy --public-patterns "main,setup,run" src/

    # Create backups (default behavior)
    pylint-sort-functions --fix-privacy --backup src/

    # Disable backups
    pylint-sort-functions --fix-privacy --no-backup src/

Error Handling and Edge Cases
------------------------------

The system handles various error conditions gracefully.

File System Errors
~~~~~~~~~~~~~~~~~~~

- **Permission Errors**: Skip files that cannot be read/written
- **Missing Files**: Report clearly and continue with remaining files
- **Backup Failures**: Abort rename if backup cannot be created (when enabled)

AST Parsing Errors
~~~~~~~~~~~~~~~~~~

- **Syntax Errors**: Skip files with invalid Python syntax
- **Encoding Issues**: Handle files with non-UTF-8 encoding gracefully
- **Large Files**: Process files of any size without memory issues

Reference Detection Edge Cases
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

**Import Aliases**:

.. code-block:: python

    from utils import helper_function as helper
    result = helper()  # Should be detected and renamed

**Nested Scopes**:

.. code-block:: python

    def outer():
        def inner():
            helper_function()  # Must be found in nested scope
        return inner

**Dynamic Code Patterns**:

.. code-block:: python

    # These make the function unsafe to rename
    func_name = "helper_function"
    globals()[func_name]()

    # String formatting with function names
    query = f"CALL {helper_function.__name__}()"

Usage Examples
--------------

The privacy fixer system is fully implemented and ready for production use.

Basic Privacy Fixing
~~~~~~~~~~~~~~~~~~~~~

.. code-block:: bash

    # Analyze and fix privacy issues automatically
    pylint-sort-functions --fix-privacy src/

    # Preview changes without applying them
    pylint-sort-functions --fix-privacy --privacy-dry-run src/

**Example Output**:

.. code-block:: text

    Processing src/utils.py...
    Privacy Fix Analysis:

    ✅ Can safely rename 3 functions:
      • format_output → _format_output (2 references)
      • validate_input → _validate_input (4 references)
      • calculate_hash → _calculate_hash (1 reference)

    Applied 3 renames to src/utils.py
    Backup created: src/utils.py.bak

Integrated Privacy and Sorting Workflow
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

.. code-block:: bash

    # Fix privacy issues and automatically resort functions
    pylint-sort-functions --fix-privacy --auto-sort src/

    # Combined operation with existing sorting fixes
    pylint-sort-functions --fix --fix-privacy --auto-sort src/

    # Configuration respects existing patterns
    pylint-sort-functions --fix-privacy --public-patterns "main,setup,handler" src/

**Integrated Workflow**:

1. Identify privacy violations (W9004: should be private, W9005: should be public)
2. Perform comprehensive safety analysis
3. Apply safe privacy renames with backup creation
4. Automatically resort functions with updated names (``--auto-sort``)
5. Generate detailed reports with safety explanations
6. Handle function sorting violations if ``--fix`` is also specified

**W9005 Detection Example**:

.. code-block:: python

    # Before: Private function used externally
    # utils.py contains:
    def _helper_function():  # Used by other modules
        return "help"

    # main.py imports it:
    from utils import _helper_function  # External usage detected

.. code-block:: bash

    # Privacy fixer detects W9005 and suggests:
    pylint-sort-functions --fix-privacy --auto-sort utils.py

.. code-block:: python

    # Result: Function renamed to public
    def helper_function():  # Now correctly public
        return "help"

Complex Project Example
~~~~~~~~~~~~~~~~~~~~~~~

.. code-block:: bash

    # Large project with custom configuration
    pylint-sort-functions --fix-privacy \
        --public-patterns "main,run,setup,teardown,app_factory" \
        --verbose \
        --backup \
        src/ tests/

**Advanced Safety Example**:

.. code-block:: python

    # Before: Unsafe to rename due to string references
    def helper_function():
        return "help"

    def main():
        # This string reference makes renaming unsafe
        sql = "SELECT * FROM helper_function_cache"
        result = helper_function()

**Privacy Fixer Output**:

.. code-block:: text

    ⚠️  Cannot safely rename 1 function:
      • helper_function: Function name found in string literals
        Line 6: sql = "SELECT * FROM helper_function_cache"

This conservative approach prevents breaking SQL queries, log messages, or other string-based references to function names.

- **Backup Integrity**: Confirm backup files allow complete rollback
- **Concurrent Access**: Handle files being modified during processing

**Test Data Sets**:

- **Safe Rename Cases**: Functions with clear, simple references
- **Unsafe Rename Cases**: Functions with dynamic references, string literals, conflicts
- **Edge Cases**: Complex inheritance, decorators, nested scopes, import aliases
- **Real-World Code**: Actual project code with realistic complexity

Conclusion
----------

The privacy fixer system provides a robust, safety-first approach to automatically renaming functions that should be private. The conservative design prioritizes correctness over completeness, ensuring that users can trust the automated renames while providing clear feedback about cases that require manual review.

**Key Strengths**:

- **Safety-First Design**: Multiple validation layers prevent incorrect renames
- **Comprehensive Analysis**: Finds all reference types through AST traversal
- **Clear User Feedback**: Detailed reports explain decisions and limitations
- **Integration**: Builds on existing W9004 detection and configuration systems
- **Testability**: Designed with comprehensive testing in mind

**Future Enhancement Opportunities**:

- **Machine Learning**: Could potentially improve dynamic reference detection
- **Interactive Mode**: Allow users to review and approve individual renames
- **Batch Processing**: Optimize for processing multiple files simultaneously
- **IDE Integration**: Provide integration points for development environments

The system represents a significant step forward in automated code organization while maintaining the safety and reliability standards expected in professional development environments.
