Unified File System - Complete Implementation Summary

🎯 Overview

The bot now has a fully unified file management system where:

1. ✅ All files saved with per-user limits (configurable in .env)
2. ✅ All files accessible by code_interpreter and AI models via file_id
3. ✅ All work (data analysis, Python code, etc.) runs through code_interpreter

---

📋 Key Features

1. File Storage & Limits

• Location: /tmp/bot_code_interpreter/user_files/{user_id}/
• Metadata: MongoDB (file_id, filename, file_type, file_size, expires_at, etc.)
• Per-User Limit: Configurable via MAX_FILES_PER_USER in .env (default: 20)
• Auto-Cleanup: When limit reached, oldest file is automatically deleted
• Expiration: Files expire after FILE_EXPIRATION_HOURS (default: 48 hours, -1 for permanent)

2. Supported File Types (80+ types)

# Tabular Data
.csv, .tsv, .xlsx, .xls, .xlsm, .xlsb, .ods

# Structured Data
.json, .jsonl, .ndjson, .xml, .yaml, .yml, .toml

# Database
.db, .sqlite, .sqlite3, .sql

# Scientific/Binary
.parquet, .feather, .hdf, .hdf5, .h5, .pickle, .pkl,
.joblib, .npy, .npz, .mat, .sav, .dta, .sas7bdat

# Text/Code
.txt, .log, .py, .r, .R

# Geospatial
.geojson, .shp, .kml, .gpx

3. File Access in Code

All user files are automatically accessible via:

# AI generates code like this:
df = load_file('file_id_abc123')  # Auto-detects type!

# Automatically handles:
# - CSV → pd.read_csv()
# - Excel → pd.read_excel()
# - JSON → json.load() or pd.read_json()
# - Parquet → pd.read_parquet()
# - HDF5 → pd.read_hdf()
# - And 75+ more types!

4. Unified Execution Path

User uploads file (ANY type)
    ↓
upload_discord_attachment()
    ↓
Saved to /tmp/bot_code_interpreter/user_files/{user_id}/
    ↓
MongoDB: file_id, expires_at, metadata
    ↓
User asks AI to analyze
    ↓
AI generates Python code with load_file('file_id')
    ↓
execute_python_code() runs via code_interpreter
    ↓
Files auto-loaded, packages auto-installed
    ↓
Generated files (plots, CSVs, etc.) auto-sent to user
    ↓
After expiration → Auto-deleted (disk + DB)

---

⚙️ Configuration (.env)

# File expiration (hours)
FILE_EXPIRATION_HOURS=48    # Files expire after 48 hours
# FILE_EXPIRATION_HOURS=-1  # Or set to -1 for permanent storage

# Maximum files per user
MAX_FILES_PER_USER=20       # Each user can have up to 20 files

📊 User Experience

File Upload

📊 File Uploaded Successfully!

📁 Name: data.csv
📦 Type: CSV
💾 Size: 1.2 MB
🆔 File ID: abc123xyz789
⏰ Expires: 2025-10-04 10:30:00
📂 Your Files: 3/20

✅ Ready for processing! You can now:
• Ask me to analyze this data
• Request visualizations or insights
• Write Python code to process it
• The file is automatically accessible in code execution

💡 Examples:
Analyze this data and show key statistics
Create visualizations from this file
Show me the first 10 rows
Plot correlations between all numeric columns

Code Execution

# AI automatically generates code like:
import pandas as pd
import seaborn as sns
import matplotlib.pyplot as plt

# Load user's file (file_id from context)
df = load_file('abc123xyz789')  # Auto-detects CSV!

# Analyze
print(df.describe())
print(f"\nShape: {df.shape}")

# Visualize
sns.heatmap(df.corr(), annot=True)
plt.savefig('correlation_heatmap.png')

# Export results
df.describe().to_csv('statistics.csv')

All generated files are automatically sent to the user!

🧪 Testing

Test File Upload

1. Upload CSV file → Should show detailed info with file_id
2. Check 📂 Your Files: 1/20 counter
3. Ask "analyze this data"
4. AI should generate code with load_file('file_id')
5. Code executes, results sent back

Test File Limit

1. Upload 20 files
2. Upload 21st file → Oldest should be auto-deleted
3. Counter should show 20/20

Test File Types

• CSV: pd.read_csv() auto-detected
• Excel: pd.read_excel() auto-detected
• JSON: json.load() or pd.read_json() auto-detected
• Parquet: pd.read_parquet() auto-detected
• etc.

Test Expiration
