* This file keeps track of upgrades to the data module
|
|
|
19 |
*
|
|
|
20 |
* Sometimes, changes between versions involve
|
|
|
21 |
* alterations to database structures and other
|
|
|
22 |
* major things that may break installations.
|
|
|
23 |
*
|
|
|
24 |
* The upgrade function in this file will attempt
|
|
|
25 |
* to perform all the necessary actions to upgrade
|
|
|
26 |
* your older installation to the current version.
|
|
|
27 |
*
|
|
|
28 |
* If there's something it cannot do itself, it
|
|
|
29 |
* will tell you what you need to do.
|
|
|
30 |
*
|
|
|
31 |
* The commands in here will all be database-neutral,
|
|
|
32 |
* using the methods of database_manager class
|
|
|
33 |
*
|
|
|
34 |
* Please do not forget to use upgrade_set_timeout()
|
|
|
35 |
* before any action that may take longer time to finish.
