How to close the SSL connection correctly?

[Steinadler177]

Is there a method that I can close the SSL connection which is build by Subgrounds? I checked the API document which doesn't have a similar content.

I tried to close it with contextlib, but it also can't solve this problem.

# Import the Subgrounds library
    
from subgrounds import Subgrounds
from contextlib import closing
import os


def another_function():
    

    # load_dotenv()
    graph_api_key = '<REDACTED>'
    # Create a new Subgrounds object
    with closing(Subgrounds()) as sg:


        # Load the Uniswap v3 subgraph using a specific API endpoint
        uni = sg.load_subgraph(
            f'https://gateway.thegraph.com/api/{graph_api_key}/subgraphs/id/ELUcwgpm14LKPLrBRuVvPvNKHQ9HvwmtKgKSH6123cr7')
        # <REDACTED>
        # Query the financialsDailySnapshots endpoint with a specified order, limit, and filter criteria
        latest_snapshots = uni.Query.financialsDailySnapshots(
            orderBy=uni.FinancialsDailySnapshot.timestamp,
            orderDirection='desc',
            first=1,
        )

        # Convert the query results to a Pandas dataframe and extract the first row
        res = sg.query_df(latest_snapshots).squeeze()
        pass
    print("Another function")


another_function()

which would give me two error message:

AttributeError: 'Subgrounds' object has no attribute 'close'
I can't close it like this.

sys:1: ResourceWarning: unclosed <ssl.SSLSocket fd=1588, family=23, type=1, proto=0, laddr=('local_address'), raddr=('remote_address')>

That's the real problem. When the program end, PY just simply terminate everything and trigger this error. I can read data from this, but how to safely close the connection?

There's no need to utilize contextlib.closing for this purpose, it won't add anything extra to the with Subgrounds() as sg behavior.

Unfortuntely, this SSL socket warning has crept up in a recent update to subgrounds and I haven't fully figured out where it came from. It can safely be ignored and won't affect anything and if the messages get in the way, you can use the warnings module to ignore them from the output:

import warnings                                                           
                                                                              
warnings.filterwarnings('ignore', category=ResourceWarning)

The intended usage should be as follows:

with Subgrounds() as sg:
    sg.load_subgraph("<url here>")
    data = sg.query_df([...])

You can learn more about query grouping in our docs! Let me know if you have further questions!

Understood. I'll try to import this warn filter for this module. Thank you very much! Please change the issue status on your control.
