This just deletes all the upgrade steps previous to 3.5.0. Some
small adjustments, like tweaking globals can also be applied
when needed.
Also includes an upgrade step to prevent upgrading from any
version < 2018051700 (v3.5.0) as anti-cheating measure.
Previous commits have removed/deprecated all the upgradelib functions
not used anymore in codebase. Deletion has been documented in corresponding
upgrade.txt files:
- upgrade_fix_block_instance_configuration()
- upgrade_theme_is_from_family(), upgrade_find_theme_location()
and linkcoursesectionsupgradescriptwasrun setting
- upgrade_block_positions
- upgrade_fix_config_auth_plugin_names()
and upgrade_fix_config_auth_plugin_defaults()
- format_xxx_upgrade_remove_numsections(), format_xxx_upgrade_hide_extra_sections()
and format_xxx_upgrade_add_empty_sections()
- filter_mathjaxloader_upgrade_cdn_cloudflare()
and filter_mathjaxloader_upgrade_mathjaxconfig_equal()
- get_assignments_with_rescaled_null_grades()
These have been kept because continue being used by restore:
- \core\task\refresh_mod_calendar_events_task
The values stored in these user preferences were valid for the old
flickr auth mechanism and are not usable any more. The new oauth1 based
version needs to store both the token (in the flickr_access_token
preference) and the token secret (flickr_access_token_secret). The new
version does not need to store the user's nsid.
The cryptic names of these legacy settings are a result of how dealing
with user preferences was originally implemented.
