Expected behaviour

• Do not see any deprecation warning.

Actual behaviour

• Listed some deprecation warnings.

Server information

• mysql 8.0.

Client information

• OS: linux
• Browser: brave.

Additional information

• I have just detected that the information from version.php ($plugin->supported = [39, 400];) does not related to that informed on Moodle Plugins: Logstore xAPI 2022101800 (Moodle 3.9, 3.10, 3.11, 4.0, 4.1). Should it include 401 in that range? It is not a problem for installing it on Moodle 4.1.*, though.

[jpahullo]

I have checked the Moodle path for some of those events, like in:

https://github.com/moodle/moodle/tree/main/lib/classes/event

in particular:

https://github.com/moodle/moodle/blob/MOODLE_401_STABLE/lib/classes/event/content_viewed.php

and yes, there is the deprecation message.

If I understand it correctly, since this plugin collects all possible events in Moodle, we will see these deprecation messages, unfortunately.

So, maybe it is not a problem really. Maybe we just need to know that this deprecation warnings appear if developer level debug is activated on Moodle.

[jpahullo]

The real problem, maybe, is that these deprecation messages appear everywhere, on every single page from administration menu and also on the Moodle Home page (moodle.url/). These deprecation messages do not appear on the moodle.url/my/ page nor on moodle.url/my/courses.php.

Should these deprecation messages appear only when editing the plugin parameters and while running the scheduled task, if the developer level debug is activated?

It is like the plugin is loaded on every single page.

If we are telling the plugin that the events will be sent through scheduled task, maybe there is no need to load the plugin on every page.

I do no know, just mentioning it.

Thanks,

Jordi

What I detected also is that events from deprecation messages does not appear on the list of candidate events to send into the LRS. So, the list of events eligible to be sent into LRS seems correct.

The only problem is regarding seeing everywhere the deprecation messages.

Without this plugin, it does not happen.

Thanks,

Jordi

I have reached to know why this debugging messages are shown.

In our Moodle we make use of $CFG->debugusers = '...';. In the debugging() function, it is considered as $forceddebug if this variable is set and the current user is in that list of users.

My idea was what it is actually done already on the core:

https://github.com/moodle/moodle/blob/main/report/eventlist/classes/list_generator.php#L47-L52

However, I realize that having the $CFG->debugusers in use, it has no effect.

Would you like to be provided with a patch like this?

+    $CFG->debugusers = $debugusers;

     return array_filter($availableevents, function($k) use ($environmentevents) {
         return in_array($k, $environmentevents);

With this patch, we do not see any debugging message while navigating through administration options. It is really annoying.

What do you think?

[jpahullo]

Finally, we have added this patch #858 to our Moodle site, so that we would like to contribute it to you and this plugin.

Thanks a lot for your support.
