Add environment check for versions not supporting PHP 7.4

XMLWordPrintable

    • MOODLE_36_STABLE, MOODLE_37_STABLE
    • MOODLE_35_STABLE, MOODLE_36_STABLE, MOODLE_37_STABLE
    • Hide

      Note: Testing this issue requires, for some points, a running version of PHP 7.4 (at the time of writing, current version is PHP 7.4rc1).

      Note2: Valid trick, alternatively, if finding a working version is hard... the lib/environmentlib.php file can be edited, after every checkout, replacing the two existing calls to phpversion() by, simply: '7.4.0' (quotes included).

      A) Using PHP 7.1.x - All upgrades work (all supported versions)

      1. Install a Moodle 3.5.x site (MOODLE_35_STABLE)
      2. Upgrade to 3.6.x (MOODLE_36_STABLE)
      3. Upgrade to 3.7.x (MOODLE_37_STABLE)
      4. Upgrade to 3.8dev (master).
      5. Verify that all the upgrades above work without problem.

      B) Using PHP 7.1.x - Upgrades to 36 & 37 with PHP 7.4 don't work

      1. Install a Moodle 3.5.x site (MOODLE_35_STABLE)
      2. Switch to PHP 7.4 (or use the valid trick)
      3. Try to upgrade to 3.6.x (MOODLE_36_STABLE)
      4. Verify that upgrade doesn't work and you get the "PHP version 7.4 is not supported" message.
      5. Try to upgrade to 3.7.x (MOODLE_37_STABLE)
      6. Verify that upgrade doesn't work and you get the "PHP version 7.4 is not supported" message.
      7. Try to upgrade to 3.8dev (master).
      8. Verify that the upgrade works without problem.

      C) Confirm that environment.xml is 100% the same over all branches

      1. Verify that the following git commands return no differences (empty output) 

        git diff MOODLE_35_STABLE master -- admin/environment.xml
        		 
        git diff MOODLE_36_STABLE master -- admin/environment.xml
        		 
        git diff MOODLE_37_STABLE master -- admin/environment.xml

      On Moodle 3.6 and 3.7, add an environmental check about PHP 7.4 not being supported.

      See previous MDL-63421 as reference for this and the behavior in previous branches (3.4 and 3.5).

      Changes are added to all supported versions (security-only included).

      Usual changes to perform to Moodle Docs include (updated to the new PHP 7.4 information):

      • A note in the PHP 7 page about the WIP and the current status, like this.
      • TODO (docs_required) Whenever the new version release notes is available (near release) something like this.
