# This shell script is for ElectrumX docker containers using https://github.com/lukechilds/docker-electrumx
# This script is to solve the ElectrumX DB::flush_count overflow meme https://github.com/kyuupichan/electrumx/issues/185
# A flush_count would overflow after 455 days for Bitcoin. For altcoins with a faster blocktime it happens much quicker.
# This script is originally written for Viacoin with a blocktime of 24 seconds (25x faster than Bitcoin so the flush count needs to be done more often.

# Please use the right environment variables for your ElectrumX container 
# DAEMON_URL, COIN and -V

# original usage from https://github.com/lukechilds/docker-electrumx
#
#docker run \
#  -v /home/username/electrumx:/data \
#  -e DAEMON_URL=http://user:pass@host:port \
#  -e COIN=BitcoinSegwit \
#  -p 50002:50002 \
#  lukechilds/electrumx

# please note in this script -v is different:
# -v /root/electrumx:/data \
# You need to change this if you want it to work 
# This script is for now only tested on Viacoin with VialectrumX fork
