//TODO: Rewrite this so its cleaner
// BigDump ver. 0.28b from 2007-06-08
// Staggered import of an large MySQL Dump (like phpMyAdmin 2.x Dump)
// Even through the webservers with hard runtime limit and those in safe mode
// Works fine with Internet Explorer 7.0 and Firefox 2.x
// Author: Alexey Ozerov (alexey at ozerov dot de)
// AJAX & CSV functionalities: Krzysiek Herod (kr81uni at wp dot pl)

// THIS SCRIPT IS PROVIDED AS IS, WITHOUT ANY WARRANTY OR GUARANTEE OF ANY KIND
// USAGE
// 1. Adjust the database configuration in this file
// 2. Drop the old tables on the target database if your dump doesn't contain "DROP TABLE"
// 3. Create the working directory (e.g. dump) on your web-server
// 4. Upload bigdump.php and your dump files (.sql, .gz) via FTP to the working directory
// 5. Run the bigdump.php from your browser via URL like http://www.yourdomain.com/dump/bigdump.php
// 6. BigDump can start the next import session automatically if you enable the JavaScript
// 7. Wait for the script to finish, do not close the browser window
// 8. IMPORTANT: Remove bigdump.php and your dump files from the web-server
// If Timeout errors still occure you may need to adjust the $linepersession setting in this file
// LAST CHANGES
// *** Improved error message for file open errors
// *** Handle CSV files (you have to specify $csv_insert_table)
// *** Restart script in the background using AJAX
