framework: StreamHandler class not found when logging deprecation warnings

Laravel Version: 8.80
PHP Version: 8.1
Database Driver & Version: mysql 8

Description:

When trying to use deprecation logging feature, some of my endpoint crashes with error 500 and nothing is catched in laravel’s logs. I found this in /var/log/nginx/myproject-error.log :

[error] 815505#815505: *1186160 FastCGI sent in stderr: "PHP message: PHP Fatal error:  Uncaught Error: Class "Monolog\Handler\StreamHandler" not found in /home/forge/myproject/vendor/laravel/framework/src/Illuminate/Log/LogManager.php:175

It looks pretty similar to https://github.com/laravel/framework/pull/39938

Steps To Reproduce:

in config/logging.php :


'deprecations' => env('LOG_DEPRECATIONS_CHANNEL', 'null'),

'channels' => [
        ...
        'php_deprecation_warnings' => [
            'driver' => 'single',
            'path' => storage_path('logs/php-deprecation-warnings.log'),
        ],
]

in .env :

LOG_DEPRECATIONS_CHANNEL=php_deprecation_warnings

And unfortunately, I can’t reproduce it locally either, so I have no way to inspect what the initial exception is.

you should always update config files when upgrading Laravel versions. Tools like Laravel Shift can greatly help with this.

Totally agree with you. Only that the config for the emergency logger, in this case, is what is the default in the code any way.

But I’ll add the emergency logger and test.

Hey @JackWH yea, got quite an amount of time into tracking this thing 😅 . Most of the currently relevant information is stowed away in the thread at https://github.com/php/php-src/issues/8164. It just so happens that I posted in there earlier today stating I would try out 8.1.6RC1. Currently running 8.1.6RC1-fpm in one of the sites in production which as of yet hasn’t gone haywire 🤞 (although it might take a couple of days).

I don’t have a way to reproduce this. I propose that we wait a little bit more, until we have other people with the same issue (if any…) and maybe they are able to provide us a way to reproduce this.

Meanwhile, if you are able to understand what’s happening, let me know.

I encountered the same error in our staging environment this morning after upgrading to framework version v8.83.1. Could not get it to trigger locally though.

Rolling back to v8.83.0 did not solve it though.

monolog versions: 2.3.5

We use LOG_DEPRECATIONS_CHANNEL=stderr
