DB::flush_count overflow fix for ElectrumX servers running in a docker container

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 kyuupichan/electrumx#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

  -v /home/username/electrumx:/data \
  -e DAEMON_URL=http://user:pass@host:port \
  -e COIN=Viacoin \
  -p 50002:50002 \
  viacoin/electrumx

please note in this script -v is different:

-v /root/electrumx:/data \

You need to change this if you want it to work

• flush
• cronjob every x days to flush
• make it easier to use

sudo crontab -e

add to the end of the file

55 23 * * * /path/to/flushcount.sh

Feel free to contribute, this would help others running ElectrumX within a docker container
