MMM-CalendarExt3 only one calendar not updating

[sdetweil]

@MMRIZE will have to advise. this is the depth of my knowledge

i work on the default calendar
well, one thing
when you refresh the page, all the modules web components are reloaded. the default cal sends a request to its node helper to get events. and it has them already, so sends immediately

and of course because the default cal will be shown, its shows with the correct events, right??

[emlowe]

Yea, I believe the default calender is working and broadcasting correctly - not sure exactly where Ext3Agenda is having problems - but I have a few ideas I plan to try out.

[emlowe]

Bah! I have to apologize - I was on the develop branch but apparently, I was some commits behind and I think I was missing the commit that fixed the “clipping” problem

I made sure to update to the head of develop and things are working much better now. So it seems all along it has been the known issue

Doh!

[emlowe]

Actually have to take this back. Currently testing running in server only mode and a browser so I can see the console easier

When I see in the log this line:

[2025-01-27 13:52:24.893] [INFO] Calendar-Fetcher: Broadcasting 22 events from <redacted>

I can say that modules are NOT getting any calendar notifications, despite this log entry. They are not broadcast. I added some code to Ext3Agenda to print out when it gets any notification, and it never gets any CAL items. (I see it getting DOM_CREATED, DOM_UPDATED, etc,etc)

I see in the console log the following:

sorting events count=0
slicing events total maxcount=100

which seems odd given that the helper reported broadcasting 22 events. Those items repeat in the console log , but it’s always sorting events count=0

UNTIL I refresh the browser - Now I see the Ext3Agenda module getting CALENDER_EVENTS and sorting events count=22

[emlowe]

I guess I should have run some tests with just the standard calendar module.

Now just using the standard calendar module - and it just says “Loading” despite having also printed “Broadcasting 22 events from”

[sdetweil]

@emlowe as you updated to the develop branch, did you also redo the npm run install-mm

[emlowe]

I did yes - so the current test results are this

The calendar did eventually appear - but it took quite some time - I wasn’t watching, so I don’t know when exactly - I’ll test again. But it was several minutes after the log output of “broadcasting 22 events”

[sdetweil]

@emlowe the default for ext3 is 30 mins
if missed at waitFetch

only see the timing in
pm2 log

default calendar working, right?

[emlowe]

@sdetweil No, I’m stopped testing Ext3 and I am only testing the default calendar.

it is not working - I see Loading... for some number of minutes or hours, I haven’t determined any consistency. This test run is now past 45 mins and it still says Loading… despite having broadcast the events 9 times:

still says Loading ... - if I refresh the browser page - then they all appear immediately

[sdetweil]

@emlowe can you extract those events out to a file

curl -sL theurl >somefile.txt
and share the file and your calendar config in an email to me
same userid at gmail

so i can look at it

one other thing is open the developers window console tab
ctrl-shift-i, select the console tab
or do
npm run start:dev

and see if there are any errors
the browser side broadcasts so it GOT the events block
then it processes for the ui

[emlowe]

@sdetweil No errors in the console log

If I wait long enough where this seems anywhere between 15min to an hour or more, they do appear without a manual refresh.

maybe it’s a complexity issue - when I curl the calender link (it’s a google private ICS link) - the resulting file is 4.8MB - I imagine parsing that is somewhat time-consuming

[sdetweil]

@emlowe yes, and new code takes longer than old with lots of events

what is the calendar refreshinterval

[emlowe]

@sdetweil You mean fetchInterval: 5 * 60 * 1000?

the calendar module doesn’t have refreshinterval does it?

[sdetweil]

@emlowe fetchInterval is same

[emlowe]

I added various log outputs to node_helper.js and calendar.js

node_helper is sending the socket notification for CALENDAR_EVENTS
this is not received by the front end code in calendar.js

I don’t know what happens to it, but I added logging to print out in calendar.js whenever the socketNotificationReceived handler is called and it doesn’t print.

(unless I refresh the page - at which point it does)

[emlowe]

Something even stranger - if I immediately refresh the page it also works. Here I mean is:

npm run server
got to browser and bring up host:8080
calendar will say “Loading” for a very long time
(despite the events getting broadcast)

But if I :
npm run server
go to browser and bring up host:8080
calender says “Loading”
Refresh the page immediately
calendar says “Loading”
calendar will immediately show the events as soon as the events are broadcast

@emlowe oh, “cool” ugh, i opened an issue about that last year

just reopened
https://github.com/MagicMirrorOrg/MagicMirror/issues/3380

can you add the contents of your post in an comment
actually this one

[MMRIZE]

Hmmm… I was in our traditional ceremony with my family - a lunar new year, so I couldn’t catch this post. Sorry.
Anyway, this symptom is not my module’s fault, right? There were some reports similar to this, but not figured out.

[sdetweil]

@emlowe can you try this , configure bigger socketio buffer
see the post in the issue

[sdetweil]

ok, that didnt help
