) -> StringExpand description
Checks if the given log file exceeds the maximum allowed size (in bytes). If so, it appends a sequence number to generate a new file name. Returns the final log file path to use.
- file_path: the initial time-based log file path.
- base_file_path: the original base log file path.
- date_str: the current date string.
- max_size: maximum file size in bytes (e.g., 1GB).
