Btcpool-slparser (share log parser) module analysis core mechanism Summary

• Three functions are supported:
  ??Specify the date and UID to print the share information of the user specified by the specified date to stdout.
  ????When uid = 0, the share information of all users on the specified date is printed.
  ??Specify date but no UID, read sharelog of the specified date, and write the statistics to the database.
  ????Statistics by worker, user, and pool: accept1h, accept1d, score1h, score1d, reject1h, and reject1d
  ????The database only retains statistics for the last three months
  ??If neither date nor uid is specified, the system listens for file changes, reads share and statistics, and writes data to the database every 15 seconds.
  ???? * Start the HTTPd service at the same time and enable serverstatus and workerstatus.
