[Python] Discord.py logging in multiple times when restarted

I'm working on a project that has a Discord client running in a background thread to listen to incoming messages. I noticed each time the client is stopped & restarted, it logs in 1 extra time, as shown below.

The session ID is the same for each group of logins but different between groups.

Below is basic code I wrote to test this bug and get the output above. I have both discord.py and discord.py-self installed.

import discord
from discord.ext import tasks
import threading
import time

USER_TOKEN = 'aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa'

class BgThread(threading.Thread):
def run(self):
self.client = self.DiscordClient()
try:
self.client.run(USER_TOKEN) # blocking
except Exception as ex:
print('The DiscordClient errored.')
print(str(type(ex)))
print(str(ex))
print(str(traceback.format_exc()))
print('Closed')

class DiscordClient(discord.Client):
def __init__(self):
super().__init__()
self.shouldStop = False

async def on_ready(self):
print('Ready. ' + str(len(self.sessions)) + ' sessions, ' + str(len(self.connections)) + ' connections, ' + \
str(len(self.relationships)) + ' relationships')
self.checkShouldStop.start()

@tasks.loop(seconds=1.0)
async def checkShouldStop(self):
if self.shouldStop:
await self.close()

if __name__ == '__main__':
while True:
# Make and run a new background thread.
bgThread = BgThread()
bgThread.start()
time.sleep(5)

# Stop the background thread.
bgThread.client.shouldStop = True
while (bgThread.is_alive()):
time.sleep(0.5)
time.sleep(3)


Here is a filtered Wireshark capture from running the code above. The filter is basically (ip.src==anyOfDiscordsIPs || ip.dst==anyOfDiscordsIps) && (tcp.connection.syn || tcp.connection.fin || tls.handshake.type==1 || tls.handshake.type==2). Discord has 10 IP addresses according to the DNS response I received, so the filter is decently long.

The Wireshark capture appears the same for each of the 3 times the Discord client connected. That, plus the number of sessions not increasing in my program's "Ready" output each time, tells me this is most likely just a logging issue and not a real "logging in multiple times" issue. However, I am not confident in this conclusion.



Anyone know why this bug is happening? I'm making a brand new BgThread object each time, so there's also a brand new discord.Client object each time.
