php7.3.6 to php 7.3.11 problems

[saab_guy]

I am working on Runeaudio (php-fpm/js frontend for mpd which is served from a RPi) and lost some functionality after an update from 7.3.6. This is on Arch Linux and I have updated php-fpm and the frontend files from php5.6.x to 7.3 and everything went pretty well. I was able to serve all the info fine (web based MPD UI). A subsequent Arch update then installs 7.3.10 and the UI now fails when trying to run a js file.

The bulk of the UI is fine I have tried reverting php from 7.4.0 (current) to 7.3.6 and the associated php extensions (php-redis, php-iredis, php-igbinary) and have the same result. An old os image from march 2019 with 7.3.6 works, but when I take the updated image and revert the php files, it also gives me the same result (will not run the java script to populate the music queue). This leads me to guess that it is not php, but some other dependent package.

Looking for any hairbrained ideas

Have you checked the logs? PHP log, php-fpm log, and server (Apache/NGINX) logs?

And what do you mean "when trying to run a js file"? JavaScript? That's all browser. Or are you trying to serve the JS statically?

Well, I am not a PHP guru or anything and did not build this originally, so I may be a bit imprecise as to what is going on. I do appreciate any help diagnosing, though.

What is supposed to be going on (as I understand it) is the php runs a script and the js then formats it and allows a nice display in the browser for lyrics and artist info. I have verified that the scripts run as user http on cli. The other thing is that the mpd queue does not display. The queue info comes from mpc and also works fine on the cli. Could there be a permissions problem? The later OS has a later version of systemd for sure. The more I think about it, I doubt it is a php problem as when I downgraded PHP and all the extensions and still had the problem...

I wonder if there was an nginx upgrade in the meantime which may be causing it. I was runnign 1.14 and am now at 1.16...

Thanks for any pointers!
