Translations on debian 'bookworm' systems may cause server errors

Describe the bug

This is a follow up of issue #5147. With the patch train provided by @netniV on top of the #5147 commits, the error message is still the same. I verified that /usr/share/php is in the include_path according to the cacti viewtech phpinfo page (although I couldn't find where it set).

[Thu Jan 12 15:27:31.996663 2023] [php:error] [pid 1005126] [client 127.0.0.1:38190] PHP Fatal error:  Uncaught Error: Class "PhpMyAdmin\\MoTranslator\\Cache\\InMemoryCache" not found in /usr/share/php/PhpMyAdmin/MoTranslator/Translator.php:115\nStack trace:\n#0 /usr/share/cacti/site/include/global_languages.php(379): PhpMyAdmin\\MoTranslator\\Translator->__construct()\n#1 /usr/share/cacti/site/include/global_languages.php(190): load_gettext_motranslator()\n#2 /usr/share/cacti/site/include/global.php(539): include_once('...')\n#3 /usr/share/cacti/site/include/auth.php(27): require_once('...')\n#4 /usr/share/cacti/site/settings.php(25): include('...')\n#5 {main}\n  thrown in /usr/share/php/PhpMyAdmin/MoTranslator/Translator.php on line 115

In Debian, the version in stable (bullseye) seems to work as expected. The php-phpmyadmin-motranslator package has changed since bullseye, the caching is new.

Although I believe this is a problem that mostly lies with Debian, I'm glad with the help offered by @netniV. I hope we can improve the code to help debugging, even if I need to fix the issue in the end in Debian.

[netniV]

Those logs look good. I'm going to commit the patch we have, and then if we need to adjust that, there'll be a follow-up commit.

[netniV]

There does seem to be a problem with the javascript includes though... need to check that.

Hi @paulgevers,

Unfortunately, I don't have those packages. My system works with the current MoTranslator.

Can you possibly zip up the /usr/share/php folder to send over those packages installed for me? I can then replace my local version and see what's going on (after backing mine up first of course!). Otherwise, I'd need a bullseye system to properly test on.

One thing you could try and do is replace the use of Translator.php and StreamReader.php with autoload.php alone. That may make things work properly.

[paulgevers]

https://packages.debian.org/sid/all/php-phpmyadmin-motranslator/download has links to the Debian packages that you can use to get the files (obviously in a tiny bit weird container, but alas). Let me know if that works for you.

[paulgevers]

And replacing

            'files' => ['Translator.php', 'StringReader.php' ],

with

            'files' => ['autoload.php' ],

seems to work.

[netniV]

OK, so I think we will update with that and I will test if with works with the current environment, since I have that installed.

[paulgevers]

By the way (maybe worth a different report) after switching the language in the settings, you need to clear your session cookie to make it active.

[netniV]

Yes, please create a separate issue for that. I thought that had been handled previously though.
