While, right now, sites using long (> 10 chars) $CFG->prefix
can continue working (because we still don't have any table
> 28 chars), as soon as some new table with long name is added,
it won't work with PostgreSQL anymore (if the 63 limit is raised).
Hence, this environmental check will verify on both install and
upgrade that the $CFG->prefix is always <= 10 chars.
Sites with longer prefixes will need to rename all their tables
(and maybe other objects, depending on the dbtype) to use a shorter
prefix.
Do not enclose \core_grades_renderer::user_heading() in
$OUTPUT->heading() and enclose the user's name in the user heading in
<h2> tags instead.
- Having <div> inside <h2> results in errors in HTML validation.
- Enclosing the whole user heading in <h2> results in the other
elements in the user heading (Message, Add to contacts) to be announced
to screen readers which can result in confusion.
TinyMCE has a default entity_encoding 'named',
which causes text with diacritic symbols to be converted to HTML entities,
e.g. pâté will be convert to pâté
That will be a problem with the Glossary auto-linking filter if a course has a text concept like pâté,
then the filter will likely fail to get the text concept.
Changing the TinyMCE entity_encoding to 'raw' will resolve the problem.
The token information was not being properly cleared from the $SESSION.
As a result, certain errors were occurring when users attempted to
reconnect within the same session.
When updating a manual enrolment instance, the value of 'notifyall' field must be calculated automatically based on the value of
'expirynotify' field. The relevant plugin's method missed that, thus, the value of 'notifyall' field was never updated when
editing a manual enrolment instance and changing the 'expirynotify' setting.
A functional test has been added to test the entire behaviour of the relevant plugin's method.
When the user picture is being rendered as a link but the user's full
name is not being included in the link and the alt text turns out to be
empty, we could end up with a link without a discernible text. This is
an accessibility issue that will affect screen reader users. If this is
the case, use the full name as the user picture's alt text.
* Add sr-only column headers for the select and actions columns.
* Define unique IDs for the preset name links using array indices.
* Label the radio buttons via aria-labelledby attribute pointing to
the ID of the preset's link.
