constant LoggerChannel::MAX_CALL_DEPTH in Drupal 9

Same name and namespace in other branches

1. 8 core/lib/Drupal/Core/Logger/LoggerChannel.php \Drupal\Core\Logger\LoggerChannel::MAX_CALL_DEPTH

Maximum call depth to self::log() for a single log message.

It's very easy for logging channel code to call out to other library code that will create log messages. In that case, we will recurse back in to LoggerChannel::log() multiple times while processing a single originating message. To prevent infinite recursion, we track the call depth and bail out at LoggerChannel::MAX_CALL_DEPTH iterations.
