Added two new buttons to the group page to bulk enable or disable the
selected groups messaging settings.
Supporting Javascript modules were also added to disable/enable the
buttons depending on the groups selected in the picker.
Previously group bulk actions were handled by prepending
_act in the value of the input, and then using a custom function that
accessed $_GET and $_POST to determine which was pressed.
This was refactored in favor of the more standard method of using
optional_param.
Previously the content of the stored file was extracted and stored in a
variable, passed around, and then submitted to MoodleNet. This results
in very high memory consumption when dealing with MoodleNet.
The stored_file should be passed around as a first-level param to
discourage this, and the content should _never_ be loaded into memory.
Instead file streams and resources should be used to allow Guzzle/Curl
to buffer the file from disk/other storage straight to MoodleNet.
This change introduces a new get_psr_stream() method to:
* stored_file
* file_system
This allows us to fetch a Psr Stream implementing the
PSR\Http\Message\StreamInterface and pass it into Guzzle, which means
that there is no need to load the entire file content into memory to
serve it.
We shouldn't invent fileareas with invalid values (specifically in
this case, the `itemid` overflowed maximum length of the field on
Oracle).
Given the generated file is transitory in nature, instead store it
in the users draft area.
It's possible to have some Moodle components soft linked instead
of being real directories within codebase (within dirroot).
For example, Composer's "vendor" directory can be soft linked
(from elsewhere), or also plugins can be installed using soft
links.
In those cases, Moodle calculates the $SCRIPT global as null. And,
then, string operations on it are emitting a PHP deprecation message
with PHP 8.1 and up.
This fix just ensures that the behaviour is the same than before
PHP 8.1, aka: ltrim(null) = '' (empty string), without any PHP warning.
This makes it possible to share a single activity to a MoodleNet
instance (which has been enabled for sharing in site admin).
This utilises the core\moodlenet\activity_packager to create an
activity backup, then sends it using the MoodleNet create resource
API specification.
