  2. MDL-34086 META: Increase robustness of upgrade from 1.9 to 2.2
  3. MDL-25948

Sites using 1.9.x, but originally installed with < 1.7, fail upgrading to 2.0 due to null fields in mdl_user table

    • PostgreSQL
    • MOODLE_20_STABLE, MOODLE_21_STABLE, MOODLE_22_STABLE

      1. Install Moodle 1.6 using Postgres.

      I had some issues here with getting Moodle's installer to generate the config.php as it could not connect to the database. I ended up having to create the file myself and specify the port. Eg.

      $CFG->dbtype = 'postgres7'; // mysql or postgres7 (for now)
      $CFG->dbhost = 'localhost'; // eg localhost or db.isp.com
      $CFG->dbname = 'name'; // database name, eg moodle
      $CFG->dbuser = 'user'; // your database username
      $CFG->dbpass = 'pass'; // your database password
      $CFG->dbport = '5432';
      $CFG->prefix = 'mdl_'; // Prefix to use for all table names

      $CFG->dbpersist = false; // Should database connections be reused?

      Remove all references of insertion to logs (eg. INSERT INTO prefix_log_display (module, action, mtable, field) VALUES ('forum', 'add', 'forum', 'name')) from lib/db/postgres7.sql and mod/forum/db/postgres7.sql before the upgrade as they will cause database errors. This is an issue in 1.6/1.7 so not reporting.

      2. Upgrade to 1.9, then to 2.1
      3. Ensure there are no null column errors. eg.

      Debug info: ERROR: column "lastip" contains null values.
      4. Compare the upgraded user table field attributes (default values, length etc) to those of a fresh install to ensure they are the same (note, they will be in the wrong order as the upgrade to 1.9 changes this (another issue?))
      5. Repeat, except for step 2 upgrade to 2.2

      In sites currently using 1.9.x, that have been originally installed with < 1.7 and then upgraded to 1.9 (even passing through 1.8), the mdl_user table have many NULLable columns without DEFAULTs.

      This will cause upgrading to 2.0.x failing due to db errors.

      -----------------------------------------------------------------
      I attached a simple SQL script that add DEFAULTs and sets NOT NULLs, as a freshly installed 1.9.x (please edit to change table prefix)
