Describe the Bug

The same as #1269 , It should have be solved by #1270 . However, it still the same, when running occ, which make the occ not run.

Expected Behavior

can run occ recognize:download-models in shell

To Reproduce

just update to NC 31, with recognize enabled, and then run any occ, will see the "PHP Fatal error".
If diable recognize app, occ can run.
If I change the apps/recognize/lib/Service/Logger.php file like #1272, i.e., remove "string|\Stringable" in all function definitions in Logger.php, the occ will works again.

Debug log

PHP Fatal error: Declaration of OCA\Recognize\Service\Logger::emergency(Stringable|string $message, array $context = []): void must be compatible with PsrExt\Log\LoggerInterface::emergency($message, array $context = []) in /var/www/html/nextcloud/apps/recognize/lib/Service/Logger.php on line 34

Mh, that's a lot of apps. Tough to say which is the culprit, but I think you have another app that brings an old version of the LoggerInterface as a dependency which causes this error in recognize. The LoggerInterface that comes with nextcloud server is here for reference: https://github.com/nextcloud/3rdparty/blob/stable31/psr/log/src/LoggerInterface.php and it does have the same signatures that the recognize app uses.

Ok there are three file not be the same:

The_____same   ./apps/recognize/vendor/psr/log/src/LoggerInterface.php
Not_the_same   ./apps/ncdownloader/vendor/psr/log/Psr/Log/LoggerInterface.php
The_____same   ./apps/suspicious_login/vendor/psr/log/src/LoggerInterface.php
Not_the_same   ./apps/suspicious_login/vendor-bin/psalm/vendor/psr/log/Psr/Log/LoggerInterface.php
The_____same   ./apps/maps/vendor-bin/psalm/vendor/psr/log/src/LoggerInterface.php
The_____same   ./3rdparty/psr/log/src/LoggerInterface.php
Not_the_same   ./3rdparty/scssphp/scssphp/src/Logger/LoggerInterface.php

[marcelklehr]

Then it's likely ncdownloader. Can you try disabling that?

[berlin2123]

This issue persists as before. It is unrelated to whether ncdownloader or suspicious_login is enabled.

[marcelklehr]

mh, maybe it's still a different app. I definitely cannot reproduce this on a fresh install of nc 31 and recognize 9.0.7 :/

[berlin2123]

I've just identified the cause of this issue: the system installed the php-pecl-psr package. After uninstalling it, occ runs normally.

# os: rockylinux 9
dnf list installed | grep psr
# the output:
php-pecl-psr.x86_64                              1.2.0-3.el9.remi.8.3                               @remi-modular
# occ runs OK, after remove:
dnf remove php-pecl-psr

Additionally, specifying the PSR library to use in the recognize file—i.e., using the one from your own source code instead of the one installed via DNF—might help avoid this issue.

[marcelklehr]

I don't think there's more I can do than this: https://github.com/nextcloud/recognize/blob/main/lib/Service/Logger.php#L10
If you install PHP dependencies on your machine, be prepared that they might break your apps. That's how PHP works, sadly.
