To Reproduce running instance from master code on testnet: https://github.com/copernet/copernicus/commit/3a07937d0a62239de752dd1bf61a9a344a4dd023

Expected behavior quickly download the headers of all block. when peer hang we should switch to other peers to download the headers.

fixing this one

whunmr commented 5 years ago

due to simulated slow connection, at least 3 peer were disconnected.

| => grep "disconnect timeout" ~/.bitcoincash/logs/copernicus.log
2018/12/14 15:41:35.539 [W] [syncmanager.go:244]  disconnect timeout sync peer:39.108.100.122:8333
2018/12/14 16:04:15.539 [W] [syncmanager.go:244]  disconnect timeout sync peer:47.52.233.52:8333
2018/12/14 16:23:55.539 [W] [syncmanager.go:244]  disconnect timeout sync peer:206.189.115.28:8333

and finally started to download blocks:
