bloky 0.1.1

Analyzes Python code to detect blocking operations

Bloky

A Python tool that analyzes Python code to detect blocking operations that could impact performance in async contexts.

Features

• Boto3 Detection: Identifies synchronous boto3 client calls
• Database Session Detection: Finds usage of synchronous Session instead of AsyncSession
• File Operations: Detects blocking file I/O operations
• Network Calls: Identifies synchronous HTTP requests
• Recursive Scanning: Analyzes all Python files in directories and subdirectories
• Detailed Reporting: Provides comprehensive reports with code snippets

Installation

Install from source (development)

pip install -e .

Install from PyPI (when published)

pip install bloky

Usage

After installation, you can use the bloky command from anywhere:

Analyze a directory

bloky /path/to/your/project

Analyze a single file

bloky /path/to/file.py

Save report to file

bloky /path/to/project --output blocking_report.txt

Alternative: Run directly without installation

python main.py /path/to/your/project

Detected Issues

The analyzer detects several types of blocking operations:

1. boto3_sync_call: Synchronous boto3 client calls
2. potential_boto3_sync: Potential boto3 operations
3. sync_session_usage: Using Session instead of AsyncSession
4. sync_db_operation: Synchronous database operations
5. sync_file_operation: Blocking file I/O
6. sync_network_call: Synchronous HTTP requests

Example Output

🚨 BLOCKING OPERATIONS DETECTED
==================================================

SUMMARY:
  boto3_sync_call: 2 occurrences
  sync_session_usage: 1 occurrences

BOTO3 SYNC CALL:
------------------------------
  📍 /path/to/file.py:15
     Synchronous boto3 client call detected
     Code: scheduler = get_boto_client("scheduler")
            target = {"Arn": arn, "Input": state_input, "RoleArn": role_arn}
            schedule = scheduler.create_schedule(

SYNC SESSION USAGE:
------------------------------
  📍 /path/to/file.py:45
     Using synchronous Session instead of AsyncSession
     Code: def playbook_list_get(
            self,
            request: Request,
            satori_db: Session,

Examples of Detected Patterns

Boto3 Synchronous Calls

# This will be detected
scheduler = get_boto_client("scheduler")
schedule = scheduler.create_schedule(...)

Database Session Issues

# This will be detected - using Session instead of AsyncSession
def some_function(self, satori_db: Session):
    result = satori_db.query(Model).all()

File Operations

# This will be detected
with open('file.txt') as f:
    content = f.read()  # Blocking read operation

Network Calls

# This will be detected
import requests
response = requests.get('https://api.example.com')  # Blocking HTTP call
