Version

Platform

Linux dev 6.6.34-0-lts #1-Alpine SMP PREEMPT_DYNAMIC Mon, 17 Jun 2024 10:01:45 +0000 x86_64 Linux

Description

The rolling file appender's prune_old_logs() function calls metadata.created().ok()? which does not work on Alpine Linux.

called `Result::unwrap()` on an `Err` value: Error { kind: Unsupported, message: "creation time is not available on this platform currently" }

This causes log files to accumulate forever.
