Bug Report
Filling out the following details about bugs will help us solve your issue sooner.
Reproducible in:
slackclient version: 2.0.0
python version: 3.7
OS version(s): Centos in Docker
I am developing a Slack chatbot in Python
Acting as a Docker container
The problem is that the container suddenly takes 100% of the CPU
CPU doesn't grow slowly, suddenly takes 100%
The same thing happens if you delete everything in slack_translate
In fact, the issue occurs even if you are running python without doing anything in the slack workspace.
Please advise if you have any problems
Here is my source
import os
import time
import slack
project_name = os.environ['project_name']
source = os.environ['source']
target = os.environ['target']
slack_api_token = os.environ['slack_api_token']
translation = os.environ['translation']
translation_token = os.environ['translation_token']
environment = os.environ['environment']
@slack.RTMClient.run_on(event='message')
def slack_translate(**payload):
event = payload['data']
if 'subtype' not in event:
channel_id = event['channel']
thread_ts = event['event_ts']
user = event['user']
webclient = payload['web_client']
message = event['text']
webclient.chat_postMessage(
channel=channel_id,
text=message
)
time.sleep(0.5)
if __name__ == "__main__":
rtm_client = slack.RTMClient(token=slack_api_token)
rtm_client.start()
