CSRF protection for the login form. The authenticate_user_login function was
extended to validate the token (in \core\session\manager) but by default it
does not perform the extra validation. Existing uses of this function from
auth plugins and features like "change password" will continue to work without
changes. New config value $CFG->disablelogintoken can bypass this check.
Significant string changes:
* completionpass_help, gradetopassnotset in mod_quiz - grade to pass set
in quiz settings not gradebook
* namecolumnmissing,core_cohort - fixing incorrect message about adding
users to a cohort
get_cache_flags() is only useful when you want multiple responses or
you don't know the name/key for the value pair. We know the name/key
here is the session ID, so use get_cache_flag() instead and gain the
performance benefit.
LTS (3.5) requires previous LTS (3.1)
This just deletes all the upgrade steps previous to 3.1.0. Some
small adjustments, like adding missing MOODLE_INTERNAL or tweaking
globals can also be applied when needed.
Also includes an upgrade step to prevent upgrading from any
version < 2016052300 (v3.1.0) as anti-cheating measure.
Next commit will get rid of/deprecate all the upgradelib functions
not used anymore in codebase.
The unit tests were failing because the upgrade step was missed.
In addition, there was a typo in a variable name, which meant that the
role was not actually synchronised.

While ldap_get_entries_moodle() PHPdocs state that it returns "array
ldap-entries with lower-cased attributes as indexes.", this is not true. It
uses ldap_get_attributes() internally, which returns both numerically indexed
attribute names, and dictionary-like entries indexed by attribute names.
Current code lowercases the dictionary-like entries, but then uses the
numerically indexed entries for the attribute names used as keys in the
returned array. The numerically indexed names might or might not be lowercased,
depending on the LDAP server and PHP version) version. E.g., OpenLDAP 2.x,
Novell eDirectory 8.x and MS Active Directory return mixed-cased attribute
names, and PHP 5.x and PHP 7.x don't lowercase them inside ldap_get_entries().
This is probably why all calls to ldap_get_entries_moodle() are followed by
calls to array_change_key_case(), even if that shouldn't be necessary.
So make sure we always return lower-cased attributs as indexes and add some
unit tests to avoid regressions in the future.
As a result of fixing the auth plugins config storage in MDL-12689, many
settings would be falsely reported as new ones by
admin/upgradesettings.php. We do not want to confuse admins so we try to
reduce the bewilderment by pre-populating the config_plugins table with
default values. This should be done only for disabled auth methods. The
enabled methods have their settings already stored, so reporting actual
new settings for them is valid.
It has never been guaranteed that settings.php would always be included
from inside the core\plugininfo\auth::load_settings() scope only.
Alternative fix would be to use $plugininfo->name but I think it is
better to be explicit here (same as we are explicit with setting names,
strings etc).
Significant string changes:
* errorinvalidbyhour,core_calendar - correcting number from 59 to 23
* cron_help,core_admin - updated recommendation to run cron every minute
* tour1_content_end, tour1_content_welcome, tour2_content_end,
tour2_content_welcome all in tool_usertours - removing reference to
3.2
* invalidsesskey,core_error and invalidsesskey,mod_wiki - more
understandable error message
* pluginname_help and pluginnamesummary in qtype_essay - explaining that
the question type can be used for file uploads
* formatnoinline, mustattach and mustrequire in qtype_essay - changing
the word 'inline' to 'online'
Some auth plugins used to have a mix of the legacy style of plugin names
in config_plugins table (such as 'auth/mnet') and the new correct
style (such as 'auth_mnet'). Attempting to rename the setting plugin via
low level SQL UPDATE could lead to duplicate key violation.
The patch introduces a new helper function to safely migrate the old
settings to the new ones, eventually informing the admin about the
values mismatch.
There is at least one LDAP server (Sun Directory Server) that doesn't
support Paged Results extension, even if it supports LDAP version 3. So
checking just for LDAP version is not enough.
If possible, we check the supportedControl attribute of the LDAP rootDSE
and see if the paged results control is available. This needs an LDAP
connection, which might not be possible to establish before we configure
some essential LDAP settings (server, bind user, password, etc.). Thus
we try to establish the connection and check the supportedControl
attribute. But if we fail, we perform only basic checks that are less
accurate and err on the side of cautiousness.
