Thanks Aaron.

I've been pulled off Mahara for a while to focus on some Moodle dev for
a client, and was going to get stuck into bug fixes and improvements to
the CSV import and export functionality. I'll happily look at this too.
Would you prioritise it higher than the CSV import/export?

Regards,

Nigel

Title:
  artefact installed upgrade problem

Status in Mahara ePortfolio:
  Confirmed

Bug description:
  When there is an artefact plugin missing and one tries to upgrade
  another artefact plugin there is an error:

  [WAR] cb (lib/errors.php:739) Failed to get a recordset: postgres7 error: [-1: ERROR:  update or delete on table "artefact_installed_type" violates foreign key constraint "arte_art_fk" on table "artefact", referer: https://mahara-testing/admin/upgrade.php
  [Tue Mar 04 08:52:46 2014] [error] [client 127.0.0.1] [WAR] cb (lib/errors.php:739) DETAIL:  Key (name)=(socialprofile) is still referenced from table "artefact".] in adodb_throw(DELETE FROM "artefact_installed_type" WHERE (plugin = ? AND name NOT IN (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)), Array), referer: https://mahara-testing/admin/upgrade.php

  This is due to the fact the missing plugin has artefacts in the
  artefact table.

  This line in lib/upgrade.php (approx line 500)
   
              delete_records_select('artefact_installed_type', $select,
                                    array_merge(array($pluginname),$types));

  needs to have some sort of checking if associated items exist for the
  plugin being removed and remove them first (or have some try { } catch
  (Exception $e) {} to let the user know that there was an issue with
  plugin A but still allow plugin B to be upgraded.
