Environment details
- OS type and version: Ubuntu 18.04
- Python version: Python 3.7.7
- pip version: pip 20.2.1
google-cloud-firestoreversion: 1.8.1
Steps to reproduce
- Create a Firestore collection called "docs" and a single document with the id "sample"
- Run the code below.
Code example
from google.cloud import firestore
import threading
firestore_client = firestore.Client()
doc_ref = firestore_client.collection('docs').document('sample')
callback_done = threading.Event()
def on_snapshot(doc_snapshot, changes, read_time):
for doc in doc_snapshot:
print(doc.to_dict())
callback_done.set()
doc_watch = doc_ref.on_snapshot(on_snapshot)
callback_done.wait(10)
doc_watch.unsubscribe()This code prints "Background thread did not exit." But I'm following the code from this documentation directly, so it seems like a bug that a warning would be printed on normal behavior.
