18 * This file keeps track of upgrades to Moodle.
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.

46 * Main upgrade tasks to be executed on Moodle version bump
47 *
48 * This function is automatically executed after one bump in the Moodle core
f9488a6f 49 * version is detected. It's in charge of performing the required tasks
39b90b51
EL
50 * to raise core from the previous version to the next one.
51 *
52 * It's a collection of ordered blocks of code, named "upgrade steps",
f9488a6f 53 * each one performing one isolated (from the rest of steps) task. Usually
39b90b51
EL
54 * tasks involve creating new DB objects or performing manipulation of the
55 * information for cleanup/fixup purposes.
56 *
57 * Each upgrade step has a fixed structure, that can be summarised as follows:
58 *
59 * if ($oldversion < XXXXXXXXXX.XX) {
f9488a6f 60 * // Explanation of the update step, linking to issue in the Tracker if necessary
39b90b51
EL
61 * upgrade_set_timeout(XX); // Optional for big tasks
62 * // Code to execute goes here, usually the XMLDB Editor will
63 * // help you here. See {@link http://docs.moodle.org/dev/XMLDB_editor}.
64 * upgrade_main_savepoint(true, XXXXXXXXXX.XX);
65 * }
66 *
67 * All plugins within Moodle (modules, blocks, reports...) support the existence of
68 * their own upgrade.php file, using the "Frankenstyle" component name as
69 * defined at {@link http://docs.moodle.org/dev/Frankenstyle}, for example:
70 * - {@link xmldb_page_upgrade($oldversion)}. (modules don't require the plugintype ("mod_") to be used.
71 * - {@link xmldb_auth_manual_upgrade($oldversion)}.
72 * - {@link xmldb_workshopform_accumulative_upgrade($oldversion)}.
73 * - ....
74 *
75 * In order to keep the contents of this file reduced, it's allowed to create some helper
76 * functions to be used here in the {@link upgradelib.php} file at the same directory. Note
f9488a6f 77 * that such a file must be manually included from upgrade.php, and there are some restrictions
39b90b51
EL
78 * about what can be used within it.
79 *
80 * For more information, take a look to the documentation available:
81 * - Data definition API: {@link http://docs.moodle.org/dev/Data_definition_API}
82 * - Upgrade API: {@link http://docs.moodle.org/dev/Upgrade_API}
