Description
Symfony version(s) affected
6.1
Description
Monolog 3.2 has made the Logger class final (see Seldaek/monolog@3cba75e ). This might lead to deprecation notices when initializing the Symfony logger
How to reproduce
Manually add Monolog ^3.2 to your composer dependencies
Initialize the Symfony logger in your code, e.g. a CLI command. When the logger is initalized for the first time (with a clean cache), you will get an error message that looks like this:
User Deprecated: The "Monolog\Logger" class is considered final. It may change without further notice as of its next major version You should not extend it from "Symfony\Bridge\Monolog\Logger". {"exception":"[object] (ErrorException(code: 0): User Deprecated: The "Monolog\Logger" class is considered final. It may change without further notice as of its next major version. You should not extend it from "Symfony\Bridge\Monolog\Logger". at /var/www/vendor/symfony/error-handler/DebugClassLoader.php:330)"} []
Possible Solution
A short-term fix would be to restrict the possible versions of Monolog to any version below 3.2 in the composer.json file of monolog-bridge
The long-term fix would be to change Symfony\Bridge\Monolog\Logger as a facade for a Monolog\Logger instance, possibly wrapping a logger and implementing the Psr\Log\LoggerInterface and Monolog\ResettableInterface for backwards compatibility.
