webrtc p2p replication Infinite loop

[BingCoke]

This is something that can happen with a certain probability (and the probability is quite high). The code repository is: https://github.com/BingCoke/replication-test.git run yarn server and run yarn dev; When multiple pages are opened simultaneously to demonstrate the synchronization effect, and I randomly click on an item to delete it, there is a chance of triggering an infinite loop—where the item gets repeatedly created and deleted indefinitely.

Another possible scenario is when I keep deleting items until all items on one page are removed, but some items may still remain on other pages. These remaining items might disappear upon refreshing the page, or they could reappear on other open pages.

btw, When I printed the changes of each find operation, I noticed that when I deleted a certain item, the value in the database would change multiple times—sometimes up to 8 times. The item would be repeatedly deleted and recreated in the database, ultimately increasing its revision count by eight.

finally

  }
]

So it ultimately wasn't deleted after all...

Hi @BingCoke I have no idea what is going on there to be honest. Please debug.
