Default Calendar module frequently refreshes

@sdetweil
i forgot to mention that i experience the same constant refresh/reload issue on both the host and browser instances of the MM that displays the default calendar module, so i guess it’s not isolated to browser on my PC where I view both MM instances.

What would the command be that I need to run to view the npm output?

@DarrenO-0 as MagicMirror is started by pm2 the command would be

pm2 logs —lines=xxxx

Two dashes in front of lines
Where xxxx is the number of most recent lines of output, default 15

You can also examine the files the logs are collected in,
In the ~/.pm2/logs. Folder, notice the . in front of pm2

The fact that you see it on other browsers confirms to
Me that this is fetch timing cycle related.
If you look at both displays at once, my guess is the refresh at the same time

I restored my MM from an image i took of it from prior to upgrading to Debian 13 and, so far, I am not experiencing the same refresh.
I’ll keep an eye on things over the next few hours and see if the issue re-occurs.

@DarrenO-0 thx. Id really like to see the logs from both for the event broadcast cycle

There was a big calendar parser change in. 33 and another coming in. 34

I just made this github issue to track this issue.

@michaelarnauts I replied to it, but there you have a different complaint.

The system design is
Pull the iCal file via the URL
It’s whatever events the source calendar wants to send , we have no control , it’s all text

We convert that to a usable list
And then figure out the repeating events and get a list that could be displayed, expired and not , as of right this second

Then we send that list out to other modules to use
MMM-CalendarExt3 for example, which displays a wall cal view, using the events in view expired or not

Then we process the not expired list and display the xx that you wanted

And repeat that whole process for the next fetchInterval
Once every xx minutes or whatever you have it set to

For each URL configured , we do the exact same process, each sending events when they are fetched. One URL processor doesn’t know about the next, they ALL run independently

I’d upgraded to .33 in mid-Oct and had only upgraded Debian from 12 to 13 earlier this month but don’t recall noticing the issue prior to the OS upgrade.

i’ll see how i go with it under Debian 12 over the weekend and probably re-upgrade to Debian 13 early next week to then see if the issue re-presents itself.
Interestingly, the calendar that contains the most events is the one that was listed in the pm2 logs when the host was issue under Debian 13.
Now that the system is back under Debian 12, I’ll recheck the logs to see if the same notification in the pm2 logs is listed.

One item i also noted in the pm2 logs was it identified that pm2 was out of date and i need to upgrade.
I’m not 100% sure, but I think my MM is currently on 6.0.6, and 6.0.13 is the latest stable version available.
I did attempt to upgrade pm2 from the instructions at pm2.io using “npm install pm2@latest -g” or “sudo npm install pm2@latest -g” and though it appeared to upgrade, it always returned an error that “-g” was an unknown command or option.
When i then run pm2 --version, it still reported that i was running 6.0.6.

@DarrenO-0 on the pm2 side there are two parts

the code on the disk
and the part running

to change the part running
you need to execute

sudo pm2 updatePM2
