Also removed write_header() and write_footer(). The reason for this
is because in core we want to know if the format being used supports
multiple sheets. To do this, and ensure we do not break third-party
dataformat plugins, we are using method_exist(). If write_header()
and write_footer() remain in the base class then this will always
be true.
Repository instances are stored in the 'repository' table. Repositories
in the table are either 'Enabled and visible' or 'Enabled but hidden'.
Hidden repositories still serve their files, but are not visible in the
filepicker UI. Disabling a repository instance removes its record from
the table.
In the original implementation of the plugin manager (see b9934a17), the
method plugintype_repository::get_enabled_repositories() correctly
returned all records from the repository table. Then as a part of the
bigger refactoring in MDL-41437, the commit bde002b8 replaced the
original method with the new get_enabled_plugins() one which started to
return visible repositories only.
As a consequence, the admin tree stopped populating setting page nodes
for hidden repository instances. So attempting to visit their setting
page threw a section error. Credit goes to Ike Quigley for debugging and
tracing this down.
This patch fixes the way how the list of enabled repositories is
populated by the plugin manager so that both visible and hidden
repositories are returned again. This does not affect the filepicker
itself as it is using its own methods for obtaining the list.
Previously we did not require the lib.php files for each module
in this ad-hoc task, which meant that the *_refresh_events functions
would only be called if some lucky sequence of events led to the
lib.php file for the module being required.
Instead we should use the component_callback function which can handle
that stuff automagically.
MS makes a big mess of returning scopes from oauth requests. They only return the custom MS scopes like
User.Read and they never return non-MS scopes (like openid, profile, email).
These combo icons are used to mark something the current element. They
are supposed to be used in places like the course outline to
mark/highlight a section as the current one. Also workshop uses them to
switch to a phase (mark it as the current one).
