Editor stylesheets are kept separately to standard plugin stylesheets so
that they can be provided to style individual iframes where loading the
standard Moodle stylesheets would be incorrect.
Unfortunately the editor stylesheet system does not consider that
subplugins may want to add small individual styling to the editor but
this is required in some situations.
The window.tinyMCE.editors API was present in version 3 of TinyMCE, but
is not present in later versions. As a result, this check tries to loop
over a variable which does not exist and throws an error in the process.
We should check that window.tinyMCE *and* window.tinyMCE.editors both
exist before attempting to loop over them.
Fixes the site home secondary nav, so that nodes added by plugins
implementing the PLUGIN_extend_navigation_frontpage callback can be
displayed for users who don't have the 'course:update' capability.
This change comprises:
- Removed course:update capability checks from site home (index.php)
and from the secondary nav view. This isn't needed since the nav is
capability aware.
- Fixed the initialisation of the secondary nav for the frontpage
course, removing erroneous duplicate 'home' nodes. The nav is now only
shown if there are nodes to display.
Allow adhoc tasks to implement this method, so they too can have
descriptive names for themselves. Default implementation added to
return the class name itself.
The changes introduced here are completely safe, just we stop
binding SITEID and, instead, embed it in the SQL.
Why? Because Oracle 21 has started to return non-sense results
when SITEID is bound.
After lots of tests, attempts, debugging... we have been unable
to find any logic to the need of this change and also, have been
unable to reproduce the problem with a standalone script that
pretty much runs the same queries that the ones changed here.
I'm sure that there is something, somewhere, but have failed
to find it, grrr.
Please read MDL-75208 and linked issues to find more information
about this problem, that is one of the biggest mysteries I've
seen recently. Maybe at the end there is a tiny detail that
explains it all, but it's really well hidden.
