Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

BfClientSession

Session is the main class, not BfClientSession.

Query

✓ from pybatfish.question import Question

✗ from pybatfish.question import Query

Use Question class, not Query.

load_questions

✓ from pybatfish.question import load_questions

Connect to a Batfish service and verify the connection.

from pybatfish.client.session import Session # Initialize session (replace with your batfish service URL) bf = Session(host='localhost', port=9999) # Check connection print(bf.check_connection())

Debug

Known issues

breakingSession constructor changed: 'host' parameter no longer accepts http:// prefix. Use just hostname.

fix

Use bf = Session(host='localhost', port=9999) without http://

affects: >=2025.0.0

breakingQuestion loading now requires explicit question directory. Default questions are not automatically loaded.

fix

Use load_questions() to load built-in questions, or provide a path.

affects: >=2024.12.0

gotchaSession must be initialized before any question or analysis. Creating multiple sessions can lead to unexpected behavior.

fix

Use a single session object for the duration of the script.

affects: all

deprecatedBfClientSession (from pybatfish.client.session import BfClientSession) is deprecated in favor of Session.

fix

Use Session class instead.

affects: >=2024.10.0

Errors

Common errors & fixes

AttributeError: module 'pybatfish' has no attribute 'client'

Importing directly from pybatfish instead of submodules.

fix

Use 'from pybatfish.client.session import Session' instead of 'import pybatfish; pybatfish.client...'

pybatfish.client.session.SessionException: Could not connect to server: Connection refused

Batfish service is not running or incorrect host/port.

fix

Ensure Batfish is running on the specified host and port. Check with: bf.check_connection()

TypeError: 'host' is an invalid keyword argument for Session()

Using outdated import path or passing url instead of host.

fix

Use Session(host='localhost', port=9999) and ensure you import from correct module.

ModuleNotFoundError: No module named 'pybatfish'

Package not installed or installed in a different venv.

fix

Run 'pip install pybatfish' and ensure the correct Python interpreter is used.
