- Publisher: Steemit
Expected behaviour
App Continues to stream posts after this is caught (stopped catching it to get the stack trace) but with try-except, it just freezes upon this error occurring.
Hoping that there is some way to restore the connection, at the same point it left at
Actual behavior
The program hangs after the crash and doesn't continue to collect posts from the blockchain (or other data for that matter)
How to reproduce
I think it may have something to do with my internet, as it is rather slow!
Just stream the blockchain as so:
steem = Steem(nodes=["https://api.steemit.com"],keys=['postingkey'])
blockchain = Blockchain()
stream = map(Post, blockchain.stream(filter_by=["comment"]))
- App version: 1.0.1
- Operating system: Ubuntu 16.04.3 LTS Xenial running inside of WSL
- Python Version: 3.6.5
