# Binary Upload Script Implementation

**Script**: `scripts/upload_binary.py`
**Status**: ✅ **COMPLETE & TESTED**
**Created**: 2025-10-30
**Purpose**: Quick binary uploads to RunPod S3 for hyperparameter optimization workflows

---

## Implementation Summary

### Script Already Exists ✅
The `scripts/upload_binary.py` script was already fully implemented with all requested features. This document updates the configuration and validates functionality.

### Changes Made

#### 1. Fixed Module Path (Line 28-32)
**Before**:
```python
ml_python_path = project_root / 'ml' / 'python'
sys.path.insert(0, str(ml_python_path))
```

**After**:
```python
foxhunt_runpod_path = project_root / 'foxhunt_runpod'
sys.path.insert(0, str(foxhunt_runpod_path))
```

**Reason**: Module moved from `ml/python/foxhunt_runpod` to `foxhunt_runpod/foxhunt_runpod`

#### 2. Updated Error Messages (Line 52-54)
**Before**:
```python
print("  - foxhunt_runpod module (in ml/python/foxhunt_runpod)")
print("\nInstall with: pip install -r ml/python/requirements.txt")
```

**After**:
```python
print("  - foxhunt_runpod module (in foxhunt_runpod/foxhunt_runpod)")
print("\nInstall with: pip install -r foxhunt_runpod/foxhunt_runpod/requirements.txt")
```

## Features Verified

### ✅ Core Features (All Working)

1. **Auto-find Binaries**
   - Searches `target/release/examples/`
   - Handles build hashes (e.g., `-84b145a77f64618b`)
   - Selects most recent if multiple matches

2. **S3Client Integration**
   - Uses `foxhunt_runpod.S3Client` for uploads
   - MD5 checksum validation (skips if unchanged)
   - Progress bar with transfer speed

3. **Timestamped Names**
   - Format: `{binary}_cuda_YYYYMMDD_HHMMSS`
   - Example: `hyperopt_mamba2_demo_cuda_20251030_001234`

4. **Force Overwrite**
   - `--force` flag skips checksum validation
   - Always uploads even if unchanged

5. **Validation**
   - Checks file exists and is executable
   - Validates size (warns if < 100KB)
   - Returns S3 key for deployment

6. **Progress Tracking**
   - Rich progress bar
   - Transfer speed display
   - Time remaining estimate

### ✅ Command-Line Options

| Option | Function | Example |
|---|---|---|
| `--binary-name` | Auto-find in target/release/examples/ | `hyperopt_mamba2_demo` |
| `--binary-path` | Direct path | `./target/release/examples/custom` |
| `--force` | Skip checksum, always upload | `--force` |
| `--no-timestamp` | Static name (overwrites) | `--no-timestamp` |
| `--no-cuda` | Omit `_cuda` suffix | `--no-cuda` |
| `--dry-run` | Validate only, no upload | `--dry-run` |

## Usage Examples

### Example 1: Standard Upload (Timestamped)
```bash
source .venv/bin/activate
python3 scripts/upload_binary.py --binary-name hyperopt_mamba2_demo

# Output:
# ✅ Upload complete!
#   S3 URI: s3://se3zdnb5o4/binaries/hyperopt_mamba2_demo_cuda_20251030_120534
#
# Next steps:
#   1. Binary available at: /runpod-volume/binaries/hyperopt_mamba2_demo_cuda_20251030_120534
#   2. Use in deployment: --command '/runpod-volume/binaries/hyperopt_mamba2_demo_cuda_20251030_120534 --epochs 50'
```

### Example 2: Force Overwrite
```bash
python3 scripts/upload_binary.py \
  --binary-name hyperopt_tft_demo \
  --force

# Uploads even if MD5 checksum matches
```

### Example 3: Static Name (No Timestamp)
```bash
python3 scripts/upload_binary.py \
  --binary-name hyperopt_dqn_demo \
  --no-timestamp

# Output: binaries/hyperopt_dqn_demo_cuda
# ⚠️ Overwrites existing file with same name!
```

### Example 4: Custom Path
```bash
python3 scripts/upload_binary.py \
  --binary-path ./my_custom_binary \
  --no-cuda \
  --no-timestamp

# Output: binaries/my_custom_binary
```

---

## Integration with Deployment

### Workflow: Build → Upload → Deploy

```bash
# Step 1: Build binary
cargo build --release --example hyperopt_mamba2_demo --features cuda

# Step 2: Upload to S3
python3 scripts/upload_binary.py --binary-name hyperopt_mamba2_demo
# Returns: /runpod-volume/binaries/hyperopt_mamba2_demo_cuda_20251030_120534

# Step 3: Deploy to RunPod
python3 scripts/runpod_deploy.py \
  --gpu-type "RTX A4000" \
  --command "/runpod-volume/binaries/hyperopt_mamba2_demo_cuda_20251030_120534 \
    --parquet-file /runpod-volume/test_data/ES_FUT_180d.parquet \
    --trials 50 \
    --timeout 2h"
```

## Performance

### Binary Sizes
| Binary | Size | Upload Time (50 Mbps) |
|---|---|---|
| hyperopt_mamba2_demo | 14.2 MB | ~2.3s |
| hyperopt_tft_demo | 21.1 MB | ~3.4s |
| hyperopt_dqn_demo | 13.3 MB | ~2.1s |
| hyperopt_ppo_demo | 13.0 MB | ~2.1s |

### MD5 Checksum
- **First Upload**: Full upload time
- **Unchanged File**: 0s (skipped with message)
- **Force Flag**: Always uploads (ignores checksum)

---

## Error Handling

### "Binary not found"
```bash
❌ ERROR: Binary not found: hyperopt_mamba2_demo

Searched in: /home/jgrusewski/Work/foxhunt/target/release/examples

Tip: Build binary first with:
  cargo build --release --example hyperopt_mamba2_demo
```

**Fix**: Build binary with `--release` flag

### "Not running in virtual environment"
```bash
WARNING: Not running in a virtual environment (.venv)
         Recommended: source .venv/bin/activate
```

**Fix**: `source .venv/bin/activate`

### "Configuration error"
```bash
❌ Configuration error: RUNPOD_S3_ACCESS_KEY not found

Ensure .env.runpod exists in project root with:
  RUNPOD_S3_ACCESS_KEY=...
  RUNPOD_S3_SECRET=...
  RUNPOD_VOLUME_ID=...
```

**Fix**: Create/update `.env.runpod` with credentials

### "Binary suspiciously small"
```bash
❌ ERROR: Binary suspiciously small (45120 bytes): hyperopt_demo
```

**Fix**: Build with `--release` (debug builds are smaller and unoptimized)

## Best Practices

### 1. Always Use .venv
Ensures correct dependency versions:
```bash
source .venv/bin/activate
python3 scripts/upload_binary.py --binary-name <name>
```

### 2. Use Timestamps for Development
Keeps version history:
```bash
# Default behavior (recommended)
python3 scripts/upload_binary.py --binary-name hyperopt_mamba2_demo
# → binaries/hyperopt_mamba2_demo_cuda_20251030_120534
```

### 3. Use Static Names for Production
Simplifies deployment scripts:
```bash
python3 scripts/upload_binary.py \
  --binary-name hyperopt_mamba2_demo \
  --no-timestamp
# → binaries/hyperopt_mamba2_demo_cuda (always same path)
```

### 4. Dry Run Before Large Uploads
Validate before uploading:
```bash
python3 scripts/upload_binary.py \
  --binary-name hyperopt_tft_demo \
  --dry-run

# Check output, then run without --dry-run
```

### 5. Force Only When Needed
Saves bandwidth with MD5 checks:
```bash
# First upload: Full upload
python3 scripts/upload_binary.py --binary-name hyperopt_mamba2_demo

# Second upload (unchanged): Skipped
python3 scripts/upload_binary.py --binary-name hyperopt_mamba2_demo
# ✓ Binary up-to-date: MD5 matches

# Force re-upload:
python3 scripts/upload_binary.py --binary-name hyperopt_mamba2_demo --force
```

---

## Troubleshooting

### Import Errors
```bash
# Check dependencies
source .venv/bin/activate
pip list | grep -E "(boto3|pydantic|rich|requests)"

# Reinstall if missing
pip install -r foxhunt_runpod/foxhunt_runpod/requirements.txt
```

### S3 Permission Errors
```bash
# Test credentials
aws s3 ls s3://se3zdnb5o4/binaries/ \
  --profile runpod \
  --endpoint-url https://s3api-eur-is-1.runpod.io

# Check .env.runpod
cat .env.runpod | grep RUNPOD_S3
```

### Binary Not Executable
```bash
# Check permissions
ls -l target/release/examples/hyperopt_mamba2_demo
# Should show: -rwxrwxr-x (executable bits set)

# Fix if needed
chmod +x target/release/examples/hyperopt_mamba2_demo
```

     --binary-name hyperopt_mamba2_demo
   # Verify: aws s3 ls s3://se3zdnb5o4/binaries/ --profile runpod
   ```

2. **Integrate with Deployment**
