      Prerequisites

      You will need to re-create the problem by manually altering db records, so an access and permission to update the database is required.

      1. On a fresh install, find the Guest user and manually set the user in the database as 'deleted'.
        • The guest user is the record in the user table with the username "guest".
        • You can run the following query
          • UPDATE mdl_user SET deleted = 1 WHERE username LIKE '%guest%';
      2. Manually remove the context of the guest user from the database.
        • You can run the following query
          • DELETE FROM mdl_context WHERE contextlevel = 30 AND instanceid IN (SELECT id FROM mdl_user WHERE username LIKE '%guest%');
      3. Purge the cache.

      Test 1

      1. Find the hash of the commit "MDL-69751 course: Handle missing guest user context" (ex. f47f244b8e777a98eaacd4b94ca3b2f469b0f542)
      2. Checkout to the specific commit by using the following command

      git checkout f47f244b8e777a98eaacd4b94ca3b2f469b0f542

      (assuming f47f244b8e777a98eaacd4b94ca3b2f469b0f542 it the commit hash of  "MDL-69751 course: Handle missing guest user context")

      1. Login as Admin.
      2. Create a Course.
      3. Go to the Course and turn editing on.
      4. Click on any 'Add an activity or resource' link to open the activity chooser.
      5. In the activity chooser:
        • confirm an error message "Coding error detected, it must be fixed by a programmer: The guest user context does not exist." is being displayed.

      Test 2

      We now need to get our branch back to normal. Run the following command:

      • testing the integration master branch (if not testing on the integration branch replace 'master' with the name of the pull master branch 'MDL-69751-master') 

        git checkout master

      • testing the integration 3.10 branch (if not testing on the integration branch replace 'master' with the name of the pull 3.10 branch 'MDL-69751-310') 

        git checkout MOODLE_310_STABLE

      • testing the integration 3.9 branch (if not testing on the integration branch replace 'master' with the name of the pull 3.9 branch 'MDL-69751-39') 

        git checkout MOODLE_39_STABLE

      1. Login as Admin.
      2. Go to Site Administration and run the upgrade.
      3. After the upgrade is finished, create a Course.
      4. Go to the Course and turn editing on.
      5. Click on any 'Add an activity or resource' link to open the activity chooser.
      6. In the activity chooser:
        • confirm that the activity chooser works properly without any error messages.
      7. Check in the database whether the guest user has been properly restored using the following query :
        • SELECT deleted FROM mdl_user WHERE username LIKE '%guest%';
        • confirm the returned result is 0;
      8. Check in the database whether the guest user context exists using the following query:
        • SELECT * FROM mdl_context WHERE contextlevel = 30 AND instanceid IN (SELECT id FROM mdl_user WHERE username LIKE '%guest%');
        • confirm that the query returns a result.

      1. That issue was not fixed by MDL-69079 patch in Moodle version 3.9.2+ (Build: 20200918)
      2. There is no guest user in  my moodle db.
      3. When you try add new activity in one course you see message "Invalid User" and  system log shows:
