Passing Tab / driver between asyncio tasks

[mrwillis]

Hi Mike,

Searched around but couldn't find an example of this. I have a bunch of asyncio tasks and I'm trying to use the Tab and Browser objects in different ones, but all my await function invocations of the Tab or Browser objects hang in the child tasks. So here's an example

driver: cdp_driver.cdp_util.Browser

async def watch_participant_count():
    """Watch the participant count and trigger shutdown when everyone leaves"""
    last_count = None
    
    logging.info("Starting participant count watcher...")
    
    page = driver.main_tab
    
    logging.info("Switching to Google")
    
    
    await driver.get("https://google.com") # HANGS HERE IF INVOKED AS A TASK
    
    logging.info("Switched to Google")

   # Try to find the participant count element
   logging.info("Looking for participant count element...")
   count_element = await page.select('div.uGOf1d', 1) # ALSO HANGS HERE IF INVOKED AS A TASK

# other function
async def join_google_meet():
    global driver, ffmpeg_process
    logging.info("Starting Google Meet session")
    driver = await cdp_driver.cdp_util.start_async(xvfb=True, lang="en")
  # ...
  # other stuff...
  # ...
  # Start participant count watcher
      participant_watcher_two = await watch_participant_count() # This works fine
  # causes problems in the function: participant_watcher = asyncio.create_task(watch_participant_count()) 

I've also tried for example directly passing in the driver and or page vs global objects, but it also seems to hang. Is there any way to do this?

See the existing async examples for correct use:

• examples/cdp_mode/raw_async.py
• examples/cdp_mode/raw_cookies_async.py
• examples/cdp_mode/raw_multi_async.py
• examples/cdp_mode/raw_req_async.py
• examples/cdp_mode/raw_xhr_async.py

Those use "Syntax Format 24", from the 25 Syntax Formats.

For general asyncio questions, the internet may be of better help.
