Third-Party Module - how to get help?
-
@ember1205 yes, u installed the original… when one develops enhancements of a git project, you make a connected copy (fork), anything u change can be sent back to the author with a ‘pull request’. I didn’t change any of his install instructions.
when u are on a git project, there is a button, clone or download(the fork, not the original), u press that, and then click the little clipboard icon to copy the url for the git clone command
at any time, you can see where your instance is sourced from by doing
git remote -vin the module folder
so, I would rename the current folder out of the way (the original doesn’t work at all for me)
cd ~/MagicMirror/modules mv MMM-ImagesPhotos MMM-ImagesPhotos.orig git clone https://github.com/sdetweil/MMM-ImagesPhotosand then restart the mirror
-
Sigh. Best laid plans… lol
At any rate - I actually rm’ed the original dir and re-did the clone using YOUR version. Came right up and started working properly right out of the gate.
Thanks for not only all of the help, but all of the patience. I do learn quickly, and this should now remain fairly firmly entrenched in my brain going forward.
Now I’m off to see how to modify the CSS of MM to change some of the font aspects for text!

@ember1205 cool. thanks for the feedback… come on back when u need help, there are amazing talented folks who can help with just about everything!

I know this is marked ‘solved’, but I wanted to mention that A ) the module does still crash with “out of memory” errors and B ) a little bit of investigative tinkering makes me think that this all ties back to a garbage collection issue with Java.
If I change the timing of how often the images change, I can effectively ‘force’ or almost eliminate a crash. The shorter the duration between photos, the more likely a crash will occur. I changed the timing to 45 seconds and saw the setup run reliably from power on at 7AM until power off at 11PM for multiple days in a row.
Shortening the window down to 5 seconds between images will cause the system to crash typically within about 10-15 minutes at a maximum.
At no time do I actively witness memory levels dropping down to zero, but that could just be “bad luck” in not seeing the issue arise when it errors out. Is there an easy way on the Pi to track a process and watch for a specific, correlating event when something crashes?

Also - I caught this error with your debug output:
Failed to load resource: the server responded with a status of 404 (Not Found) :8080/MMM-ImagesPhotos/photos:1That’s at the beginning of the console output along with another error I have seen later in the console:
MMM-ImagesPhotos Could not load photos photosrequest.onreadystatechange @ :8080/modules/MMM-ImagesPhotos/MMM-ImagesPhotos.js:65Any thoughts on those?

@ember1205 i am not aware of any debugging tools or strategy that can get to the type of issue being encountered. I have been chasing these for the last 4 years…
i also think the error reported is bogus, caused by the mishandling of some other error.
the ‘problem’ is that the browser thinks IT is in control of the content update cycle, but with all these modules running separate timer event handlers, it is not.
I have debugged a lot of ‘electron is single threaded’ problems down to , ‘you might THINK its single threaded, but it is NOT’… when the timer fires, SOMETHING is getting interrupted… in gosh knows what state…
one way you might prove this, is to turn off every other module, so only ONE does any content updating (it is a web page after all)
One of my modules has 2-10 images loaded over the top of the web page, on independent timing cycles. i traced failures to attempting to load an image, while an image load was already in progress. I added code to my module to prevent this behavior, and my failures went away.
I added a background image thing, and they returned when my module is running…
they are both loading images at the same time sometimes… and electron crashes… in various ways.I have been trying (last 6 months) to find a mechanism to serialize this across multiple modules, without changing the modules, but have failed so far.
we are also running on an age old electron (3.x), which the most recent version that will run for MM is 6.x) (7.x will not run)

:8080/MMM-ImagesPhotos/photos:1
yeh, the code attempts to load the folder… once… I haven’t debugged it cause it doesn’t matter

Thanks.
What about second error I mentioned? Or, is that essentially part of the overall error?
-
@ember1205 part of the same… looking at it now
-
ok, fixed the error message… a startup timing error…
module tried to get images from node_helper, before node_helper had established the linkage…
(if u are using my repo)
go to your MMM-ImagesPhotos folder and dogit pull
then restart mirror app

I don’t seem to be seeing that error any more, but now it’s crying about not using HTTPS (warning, not error, and specifically for Electron). For whatever reason, that warning wasn’t showing up in the console prior although I’m sure that it was there in some capacity.
I -do- see an indication of an error but can’t seem to find any error in the console.
-
@ember1205 that big pile of warning is just that warning… a couple years ago, the networking community decide that EVEY website should move away from http, to https, to reduce hacking the clear text content as it went by…
so, electron is warning that u didn’t use https

Oh, I’m well aware. This sort of stuff is “what I do” every day. I just find it interesting that I didn’t see it before, see it now, and can’t seem to find the error that is being indicated is present.
Switching to an external browser allows me to find the error - it’s actually related to one of the weather modules. The specific complaint is that I don’t have permission to load the weather map.
Failed to load resource: the server responded with a status of 401 (Unauthorized) https://api.openweathermap.org/data/2.5/forecast/daily?id=< removed>&units=imperial&lang=en&APPID=< removed>I’ll have to look and see if I can turn off the attempt to load that map.

cool…
i can’t explain why it wasn’t shown before… I see it all the time (assuming I don’t have some filter enabled to select just messages for specific modules…)…
oh I did a dummy routine to replace the MM provided one that echos notifications received,
cause the darned clock module sends an annoying notice every second. -

hasn’t this been resolved with a recent update? If not it should be.
With the update to 2.10.0 I don’t get any notifications by the clock anymore. -
@lavolp3 not different
if (self.config.displaySeconds) if u have seconds displayed on your time, u still get notices
this is the default setting (was on 2.9, is on 2.10)
-
@ember1205 you need to do another git pull…
i found a case where it doesn’t update the image anymore…

Will do.
As an aside… I directly witnessed an odd scenario the other day when I had it refreshing every five minutes… one of the images only loaded the upper half on the screen (the bottom half of the screen had no image and was blank). I could not tell what image it was as I have quite a few in rotation and the frame continued on cleanly from there with the next image.
Is that in any way related to what you found?

@ember1205 no… I have seen the slow paint issue myself many times…
electron is having some painting problem… again we are on 3.0.13, no longer supported since way back…
I had tried to get us to 6.0.12 this release, but the test system failed, and they removed this change from the 2.10 release
(but I have seen paint problems on 6.0.12 too)u can try this manually
cd ~/MagicMirror npm install electron@6.0.12 -

cd ~/MagicMirror npm install electron@6.0.12What I saw seemed to be different from a “slow paint” issue - it painted the top half and stopped. It sat there for a few seconds and then the image switched to the next one.
While upgrading manually would certainly get me to something newer for Electron, it puts me in the position of not having a “standard install” for future troubleshooting and such. It’s a double-edged sword…
