<?php
define( 'UPDATE_VERSION' , 1003 );
/**
*
* update.php - automatic system update
*
* Automatically update database schemas and any other development changes such that
* copying the latest files from the source code repository will always perform a clean
* and painless upgrade.
*
* Each function in this file is named update_rnnnn() where nnnn is an increasing number
* which began counting at 1000.
*
* At the top of the file "boot.php" is a define for DB_UPDATE_VERSION. Any time there is a change
* to the database schema or one which requires an upgrade path from the existing application,
* the DB_UPDATE_VERSION and the UPDATE_VERSION at the top of this file are incremented.
*
* The current DB_UPDATE_VERSION is stored in the config area of the database. If the application starts up
* and DB_UPDATE_VERSION is greater than the last stored build number, we will process every update function
* in order from the currently stored value to the new DB_UPDATE_VERSION. This is expected to bring the system
* up to current without requiring re-installation or manual intervention.
*
* Once the upgrade functions have completed, the current DB_UPDATE_VERSION is stored as the current value.
* The DB_UPDATE_VERSION will always be one greater than the last numbered script in this file.
*
* If you change the database schema, the following are required:
* 1. Update the file database.sql to match the new schema.
* 2. Update this file by adding a new function at the end with the number of the current DB_UPDATE_VERSION.
* This function should modify the current database schema and perform any other steps necessary
* to ensure that upgrade is silent and free from requiring interaction.
* 3. Increment the DB_UPDATE_VERSION in boot.php *AND* the UPDATE_VERSION in this file to match it
* 4. TEST the upgrade prior to checkin and filing a pull request.
