In PHPUnit 7.x and above, IsEqual->value became private and, as far
as our with exceptions class inherits from it, we cannot access to
that anymore.
So, in order to avoid that, we are overriding the constructor, capturing
the original value for own use and forgetting.
A more formal, alternative, solution would be to make our
exceptional class to inherit from Constraint and make the
class a pure dispatcher to different constraints, with IsEqual being
just one of them.
But we followed the easiest path here. Not ideal, but efective.
Namely:
- 3rd param of assertEquals() cannot be null.
- Some incorrect uses of assertNotEmpty().
- Comparing 2 strings now uses strict (===) evaluation.

Solution here is one of:
a) Return to the previous situation, making the comparison
softer. That can achieved by forcing different types, so
float == string works.
b) Changing APIs (both forms and database return strings) to
perform some conversion to floats. That would make float
comparison (with floats or strings) to work too.
The patch here follows the a) approach. Changing all the internals
for proper float handling sounds excesive when it has been working
perfectly since ever. So we went the easier route, just getting
rid of the new === comparisons when needed by changing expectation
types to float.
To generate a new composer.lock for a given Moodle branch:
- Remove composer.lock
- Remove vendor
- Remove composer caches:
php composer.phar clearcache
- Using lower PHP version supported (7.1.x for Moodle 3.7), update:
php composer.phar update

\cache::make() may return a cache_disabled subclass but callers, specifically
user/lib.php:user_create_user(), invoke \cache::purge_current_user() which was
only implemented by the cache_session subclass. Added empty
\cache::purge_current_user() which subclasses can implement, i.e.
cache_session, or not, i.e. cache_disabled.
\core_analytics\model::create and \core_analytics\model::enable methods
are called from install/upgrade scripts. Therefore, they should not
include any capability check. Their capability checks are actually
redundant, as the user capabilities are already checked in the
entry-point scripts.
These coding style issues were spotted while working on the issue. No
real changes here, just the coding style fixes attached to the patchset
for convenience.
Similarly to how the scheduled tasks work, we now automatically check
and make sure that all the models specified in the component's
db/analytics.php file exist during the installation or upgrade of the
component.
The original implementation did not work well for checking that the
given model does NOT exist. If no record was found in the
analytics_models table, the code execution continued and it reached the
moment when indicators were checked. If no indicators were provided, the
call ended up with error 'array_keys() expects parameter 1 to be array,
boolean given' (because indicators were set to false).
The functionality of the \core_analytics\manager::add_builtin_models()
method is to be replaced with automatic update of models provided by the
core moodle component. There is no need to call this method explicitly
any more. Instead, adding new models will be done by updating the
lib/db/analytics.php file and bumping the core version.
When the API had originally been designed, it was assumed that the
presence of the time splitting method implies no requirement for the
machine learning backend and that it is a sign of less performance
demanding models. So it seemed to be safe and useful to have such models
automatically enabled. That assumption did not prove to be valid. Most
of the time is spent calculating indicators that depend on log tables.
We realized it would be useful to be able to specify the default time
splitting method without the need to have such models auto-enabled.
