# Cache Analysis Configuration Verification

**Date:** 2025-11-23
**Status:** ✅ **VERIFIED COMPLETE**

---

## 🔍 Verification Checklist

### ✅ All Settings in `defaultconfig.toml`

All cache analysis settings are documented in `src/glintefy/defaultconfig.toml` under `[review.cache]`:

| Setting | Default | Type | Purpose |
|---------|---------|------|---------|
| `cache_size` | 128 | int | LRU cache maxsize for testing |
| `hit_rate_threshold` | 20.0 | float | Minimum cache hit rate % (batch screening) |
| `speedup_threshold` | 5.0 | float | Minimum speedup % (individual validation) |
| `min_calls` | 100 | int | Minimum function call count for hotspot |
| `min_cumtime` | 0.1 | float | Minimum cumulative time (seconds) for hotspot |
| `test_timeout` | 300 | int | Test suite timeout in seconds |
| `num_runs` | 3 | int | Number of runs to average for stability |

**Total Settings:** 7

## 🔗 Configuration Flow

```
defaultconfig.toml
    ↓
CacheSubServer.__init__()
    ↓ (loads config + applies overrides)
    ├─→ PureFunctionDetector()
    ├─→ HotspotAnalyzer(min_calls, min_cumtime)
    ├─→ BatchScreener(cache_size, hit_rate_threshold, test_timeout)
    └─→ IndividualValidator(cache_size, speedup_threshold, test_timeout, num_runs)
```

## 📋 Configuration Loading Code

### CacheSubServer Constructor

```python
def __init__(
    self,
    input_dir: Path,
    output_dir: Path,
    repo_path: Path,
    cache_size: int | None = None,              # ← Configurable
    hit_rate_threshold: float | None = None,    # ← Configurable
    speedup_threshold: float | None = None,     # ← Configurable
    min_calls: int | None = None,               # ← Configurable
    min_cumtime: float | None = None,           # ← Configurable
    test_timeout: int | None = None,            # ← Configurable
    num_runs: int | None = None,                # ← Configurable
    mcp_mode: bool = False,
):
    # Load config
    config = get_config(start_dir=str(repo_path))
    cache_config = config.get("review", {}).get("cache", {})

    # Apply config with constructor overrides
    self.cache_size = cache_size or cache_config.get("cache_size", 128)
    self.hit_rate_threshold = hit_rate_threshold or cache_config.get("hit_rate_threshold", 20.0)
    self.speedup_threshold = speedup_threshold or cache_config.get("speedup_threshold", 5.0)
    self.min_calls = min_calls or cache_config.get("min_calls", 100)
    self.min_cumtime = min_cumtime or cache_config.get("min_cumtime", 0.1)
    self.test_timeout = test_timeout or cache_config.get("test_timeout", 300)
    self.num_runs = num_runs or cache_config.get("num_runs", 3)
```

**Priority:** Constructor parameter > Config file > Hardcoded default

## 🧪 Verification Tests

### Test 1: All Config Keys Present

```bash
$ grep -A 20 "\[review.cache\]" src/glintefy/defaultconfig.toml
[review.cache]
# LRU cache size for testing
cache_size = 128

# Minimum cache hit rate % (batch screening threshold)
hit_rate_threshold = 20.0

# Minimum speedup % (individual validation threshold)
speedup_threshold = 5.0

# Minimum function call count to be considered a hotspot
min_calls = 100

# Minimum cumulative time (seconds) to be considered a hotspot
min_cumtime = 0.1

# Test suite timeout in seconds (applies to both batch and individual testing)
test_timeout = 300

# Number of test runs to average for individual validation (for measurement stability)
num_runs = 3
```

✅ **PASS** - All 7 settings present

### Test 2: Constructor Parameters Match Config

```python
# CacheSubServer constructor parameters
cache_size: int | None = None,           # ✅ Matches config.cache_size
hit_rate_threshold: float | None = None, # ✅ Matches config.hit_rate_threshold
speedup_threshold: float | None = None,  # ✅ Matches config.speedup_threshold
min_calls: int | None = None,            # ✅ Matches config.min_calls
min_cumtime: float | None = None,        # ✅ Matches config.min_cumtime
test_timeout: int | None = None,         # ✅ Matches config.test_timeout
num_runs: int | None = None,             # ✅ Matches config.num_runs
```

✅ **PASS** - All parameter names match config keys

### Test 3: All Config Values Used

```python
# Passed to HotspotAnalyzer
min_calls=self.min_calls,      # ✅ Used
min_cumtime=self.min_cumtime,  # ✅ Used

# Passed to BatchScreener
cache_size=self.cache_size,              # ✅ Used
hit_rate_threshold=self.hit_rate_threshold, # ✅ Used
test_timeout=self.test_timeout,          # ✅ Used

# Passed to IndividualValidator
cache_size=self.cache_size,              # ✅ Used
speedup_threshold=self.speedup_threshold, # ✅ Used
test_timeout=self.test_timeout,          # ✅ Used
num_runs=self.num_runs,                  # ✅ Used
```

✅ **PASS** - All config values propagated to sub-components

### Test 4: Syntax Validation

```bash
$ python3.13 -m py_compile src/glintefy/subservers/review/cache.py
✓ cache.py syntax OK after adding test_timeout and num_runs
```

✅ **PASS** - No syntax errors

## 📖 Configuration Documentation

### In `defaultconfig.toml`

Each setting includes:
- ✅ Comment explaining purpose
- ✅ Indication of which phase uses it (batch screening vs individual validation)
- ✅ Clear default value
- ✅ Type indication via value format (int vs float)

Example:
```toml
# Minimum cache hit rate % (batch screening threshold)
hit_rate_threshold = 20.0
```

### In Constructor Docstring

Each parameter documented:
```python
Args:
    cache_size: LRU cache maxsize (default: 128)
    hit_rate_threshold: Minimum hit rate % (default: 20)
    speedup_threshold: Minimum speedup % (default: 5)
    min_calls: Minimum calls for hotspot (default: 100)
    min_cumtime: Minimum cumtime for hotspot (default: 0.1)
    test_timeout: Test suite timeout in seconds (default: 300)
    num_runs: Number of runs to average (default: 3)
```

## 🎯 Configuration Override Examples

### Example 1: Via Config File

```toml
# Custom project config
[review.cache]
cache_size = 256              # Larger cache for bigger project
hit_rate_threshold = 30.0     # Higher bar for recommendations
speedup_threshold = 10.0      # Only significant speedups
test_timeout = 600            # Slower test suite
```

### Example 2: Via Constructor

```python
from glintefy.subservers.review.cache import CacheSubServer

server = CacheSubServer(
    input_dir=Path("LLM-CONTEXT/review/scope"),
    output_dir=Path("LLM-CONTEXT/review/cache"),
    repo_path=Path("."),
    cache_size=256,           # Override config
    hit_rate_threshold=30.0,  # Override config
    test_timeout=600,         # Override config
)
```

### Example 3: Via MCP Tool Call

```json
{
  "tool": "review_cache",
  "arguments": {
    "cache_size": 256,
    "hit_rate_threshold": 30.0,
    "speedup_threshold": 10.0
  }
}
```
