Hello everyone. How can I catch a session termination event?
I can except for ConnectionError or AuthKeyUnregisteredError, but they work only in 50% of cases when my session is terminated.
If they don't, I try to use .is_connected() and .is_user_authorized(), buy they are showing both True after termination, and if I try to do .get_me() (or actually any client-related method) it just hangs forever. No error, no response.

Like which part of my code should I implement this? Sorry I don't really know what catch_up is or how it works. Can you explain in greater detail?

This is the current code I have. Is this the most optimized/right way of writing the code? Previously I was not using asyncio (just using client.start) but a member here recommended me to try it out. But the result is the same, still seeing delays in receiving message.

async def monitor_messages():
    async with TelegramClient("session1", API_ID, API_HASH) as client:
        # Define the event handler
        @client.on(events.NewMessage(chats=SOURCE_CHANNEL))
        async def handler(event):
            if "Market Cap" in event.message.message:
                try:
                    # Extract token contract address
                    contract_address = re.search(CONTRACT_REGEX, event.message.message).group(0)
                    # Construct and send the /buy command to the trading bot
                    command = f"/buy {contract_address} {BUY_AMOUNT}"
                    await client.send_message(GMGN_BOT_USERNAME, command)
                except Exception as e:
                    logging.error(f"Error: {e}")

        await client.run_until_disconnected()

if __name__ == "__main__":
    asyncio.run(monitor_messages())

@disk6969 Hey sir. If you can recall, I have a similar use case over here where I need to detect new messages from a channel in real-time. You've mentioned switching to iter_messages is an option but has restrictive limits (i.e. unrealistic to be polling every second), and that using catch_up might be an option too. From my understanding, catch_up is intended for scenarios where the client might disconnect and you might want to process missed messages. But my purpose is focused on monitoring new incoming messages in real-time only. With that said, should I still try iter_message with a polling frequency of 1 second, or is that totally not recommended?

Thanks, but i fix it in this way:

# media = message.media
# self.obj = message

if isinstance(media, MessageMediaPhoto):
   self.downloadMedia(f"P{self.obj.id}.jpg")
   self.write(f"[ PHOTO ] - ({self.obj.id})")

Hey Juan Carlos Cautter, don't do that again (offtopic non-English) or I will ban you. You have been warned.

You don't 'need' to, unless it's imperative you create custom filename.. then prefer message.file.ext and message.file.mime_type and message.file.media.id

MessageDeleted.Event doesn't contain any reference to the topic ID, only group ID, and topic msg IDs are not unique

there's no way to know from which topic a delete event originates from?

Is there any way to detect media type?

This code always ends with an error

if self.obj.media.photo:
   self.downloadMedia(f"P{self.obj.id}.jpg")
   self.write("[ PHOTO ] - (self.obj.id)")
   
  elif self.obj.media.voice:
   self.downloadMedia(f"A{self.obj.id}.mp3")
   self.write("[ VOICE ] - (self.obj.id)")
   
  elif self.obj.media.video:
   self.downloadMedia(f"V{self.obj.id}.mp4")
   self.write("[ VIDEO ] - (self.obj.id)")
   
  elif self.obj.media.document:
   self.downloadMedia(f"D{self.obj.id}.mp4")
   self.write("[ DOCUMENT ] - (self.obj.id)")
   
  else:
   self.downloadMedia(f"-{self.obj.id}")
   self.write("[ FILE ] - (self.obj.id)")

'MessageMediaDocument' object has no attribute 'photo'

If I use that then I'll stick with using events.NewMessage?

It isn't solely for that. mainly when catch_up=True isn't passed to TelegramClient

you make a pull request if you want something added, providing the timeit benchmark code of old and new

but features aren't added in V1 telethon, but may be merged for V2
