+# Python 3.8/3.9 Compatibility Linting
+
+This document describes the compatibility linting rules integrated into the ccBitTorrent project to ensure Python 3.8 and 3.9 compatibility.
+
+## Overview
+
+The compatibility linter enforces design patterns from [`compatibility_tests/COMPREHENSIVE_RESOLUTION_PLAN.md`](../compatibility_tests/COMPREHENSIVE_RESOLUTION_PLAN.md) to prevent Python 3.10+ syntax from being introduced into the codebase.
+
+## Linting Tools
+
+### 1. Custom Compatibility Linter
+
+**Location**: [`dev/compatibility_linter.py`](compatibility_linter.py)
+
+A custom Python script that checks for:
+- **Union type syntax (`|`)**: Detects `type | None` and `type1 | type2` patterns
+- **Built-in generic types**: Detects `tuple[...]`, `list[...]`, `dict[...]`, `set[...]` without `from __future__ import annotations`
+
+**Usage**:
+```bash
+# Check all files in ccbt/
+uv run python dev/compatibility_linter.py ccbt/
+
+# Check specific files
+uv run python dev/compatibility_linter.py ccbt/session/session.py
+
+# JSON output
+uv run python dev/compatibility_linter.py ccbt/ --format json
+```
+
+**Integration**: Automatically runs as part of pre-commit hooks (see [`dev/pre-commit-config.yaml`](pre-commit-config.yaml))
+
+### 2. Ruff Configuration
+
+**Location**: [`dev/ruff.toml`](ruff.toml)
+
+Ruff is configured with:
+- **Target Python version**: `py38` (ensures compatibility checks)
+- **Ignored rules**: `UP045` and `UP007` (which suggest using `|` syntax) are intentionally ignored to enforce compatibility
+
+## Design Patterns Enforced
+
+### Pattern 1: Union Type Syntax
+
+**Invalid (Python 3.10+ only)**:
+```python
+def func(param: str | None = None) -> dict | None:
+ pass
+
+var: int | float = 1.0
+```
+
+**Valid (Python 3.8/3.9 compatible)**:
+```python
+from typing import Optional, Union
+
+def func(param: Optional[str] = None) -> Optional[dict]:
+ pass
+
+var: Union[int, float] = 1.0
+```
+
+**Detection**: The compatibility linter detects union syntax (`|`) in:
+- Function parameters: `param: type | None`
+- Return types: `-> type | None`
+- Variable annotations: `var: type | None`
+- Type aliases: `TypeAlias = type | None`
+
+### Pattern 2: Built-in Generic Types
+
+**❌ Invalid (Python 3.8 without `__future__`)**:
+```python
+_PacketInfo = tuple[UTPPacket, float, int]
+items: list[str] = []
+mapping: dict[str, int] = {}
+```
+
+**Valid Option 1 (Recommended)**:
+```python
+from __future__ import annotations
+
+_PacketInfo = tuple[UTPPacket, float, int]
+items: list[str] = []
+mapping: dict[str, int] = {}
+```
+
+**Valid Option 2 (Alternative)**:
+```python
+from typing import Tuple, List, Dict
+
+_PacketInfo = Tuple[UTPPacket, float, int]
+items: List[str] = []
+mapping: Dict[str, int] = {}
+```
+
+**Detection**: The compatibility linter detects built-in generic types (`tuple[...]`, `list[...]`, `dict[...]`, `set[...]`) and checks if `from __future__ import annotations` is present in the first 20 lines of the file.
+
+## Issue Types
+
+The compatibility linter reports issues with the following types:
+
+1. **`union-syntax-param`**: Union syntax in function parameter
+2. **`union-syntax-return`**: Union syntax in return type
+3. **`union-syntax-var`**: Union syntax in variable annotation
+4. **`union-syntax-alias`**: Union syntax in type alias
+5. **`builtin-generic-tuple`**: `tuple[...]` without `__future__` import
+6. **`builtin-generic-list`**: `list[...]` without `__future__` import
+7. **`builtin-generic-dict`**: `dict[...]` without `__future__` import
+8. **`builtin-generic-set`**: `set[...]` without `__future__` import
+
+## Integration
+
+### Pre-commit Hooks
+
+The compatibility linter runs automatically before commits via pre-commit hooks:
+
+```yaml
+- id: compatibility-linter
+ name: compatibility-linter
+ entry: uv run python dev/compatibility_linter.py ccbt/
+ language: system
+ types: [python]
+ files: ^ccbt/.*\.py$
+```
+
+### CI/CD Pipeline
+
+The compatibility linter should be integrated into CI/CD pipelines to catch issues before merging. Add to `.github/workflows/ci.yml`:
+
+```yaml
+- name: Check Python 3.8/3.9 compatibility
+ run: |
+ uv run python dev/compatibility_linter.py ccbt/
+```
+
+## Fixing Issues
+
+### Automatic Fixes
+
+Some issues can be fixed automatically:
+
+1. **Union syntax**: Replace `type | None` with `Optional[type]`
+2. **Complex unions**: Replace `A | B | C` with `Union[A, B, C]`
+3. **Built-in generics**: Add `from __future__ import annotations` at the top of the file
+
+### Manual Fixes
+
+Complex cases may require manual review:
+- Nested types: `dict[str, int | None]` → `dict[str, Optional[int]]`
+- Type aliases with unions
+- Context-specific type annotations
+
+## Examples
+
+### Example 1: Function with Union Type
+
+**Before**:
+```python
+def get_value(key: str) -> str | None:
+ return cache.get(key)
+```
+
+**After**:
+```python
+from typing import Optional
+
+def get_value(key: str) -> Optional[str]:
+ return cache.get(key)
+```
+
+### Example 2: Built-in Generic Type
+
+**Before**:
+```python
+def process_items(items: list[str]) -> dict[str, int]:
+ return {item: len(item) for item in items}
+```
+
+**After**:
+```python
+from __future__ import annotations
+
+def process_items(items: list[str]) -> dict[str, int]:
+ return {item: len(item) for item in items}
+```
+
+### Example 3: Complex Union
+
+**Before**:
+```python
+def parse_value(value: str | int | float) -> str | None:
+ try:
+ return str(value)
+ except Exception:
+ return None
+```
+
+**After**:
+```python
+from typing import Optional, Union
+
+def parse_value(value: Union[str, int, float]) -> Optional[str]:
+ try:
+ return str(value)
+ except Exception:
+ return None
+```

+
+- [`compatibility_tests/COMPREHENSIVE_RESOLUTION_PLAN.md`](../compatibility_tests/COMPREHENSIVE_RESOLUTION_PLAN.md) - Full compatibility resolution plan
+- [`dev/ruff.toml`](ruff.toml) - Ruff linting configuration
+- [`dev/pre-commit-config.yaml`](pre-commit-config.yaml) - Pre-commit hook configuration
+
+## Troubleshooting
+
+### False Positives
+
+The linter may report false positives for:
+- Bitwise OR operations (e.g., `flags | MASK`)
+- String literals containing `|`
+- Comments containing type annotations
+
+These are filtered out automatically, but if you encounter issues, please report them.
+
+### Performance
+
+The linter processes files sequentially. For large codebases, consider:
+- Running on specific directories: `uv run python dev/compatibility_linter.py ccbt/session/`
+- Using JSON output for programmatic processing
+- Excluding test files if not needed
+
+## Contributing
+
+When adding new compatibility checks:
+
+1. Add the pattern to `dev/compatibility_linter.py`
+2. Update this documentation
+3. Test with existing codebase
+4. Add to pre-commit hooks if appropriate

+Compatibility Linter for Python 3.8/3.9 Compatibility.

+1. Union type syntax (`|`) - should use `Optional` or `Union` instead
+2. Built-in generic types without `__future__` import - requires `from __future__ import annotations` for Python 3.8
+3. `tuple[...]` usage - should use `Tuple[...]` from typing for Python 3.8 compatibility
+4. `tuple[...]` in type aliases - even with `__future__` import, type aliases are evaluated at runtime in Python 3.8
+5. `Tuple[...]` usage without proper import from typing - must import `Tuple` from typing
+6. Other compatibility patterns
