invalid time str

Error message

invalid time str

What it means

clear_logs parses log file names of the form YYYY-MM-DD-HH (split on '-' must yield exactly 4 parts) into a NaiveDateTime. If the file name does not split into 4 dash-separated segments, this error is returned and the file is skipped/not deletable. It is a filename-format guard for the log cleanup job.

Solutions

1. Ensure only files named YYYY-MM-DD-HH.log reside in the log directory; move or ignore others
2. Update the parser to skip non-matching files instead of erroring
3. Align the filename regex with the current log rotation naming before cleanup

Example fix

// before
if sa.len() != 4 { return Err(anyhow::anyhow!("invalid time str")); }
// after
if sa.len() != 4 { log::debug!("skipping non-dated log file: {}", s); return Ok(()); } // treat as not-deletable

fn is_dated_log_name(name: &str) -> bool {
    name.split('-').count() == 4 && name.ends_with(".log")
}

match parse_time_str(file_name) {
    Ok(t) => /* compare and maybe delete */,
    Err(_) => log::debug!("skipping non-dated log file: {}", file_name),
}

When it happens

Trigger: The scheduled clear_logs job encounters a file in the log directory whose name, when split by '-', has other than 4 components - e.g. 'app.log', 'error-2026.log', or logs written by a different/older naming scheme.

Common situations: Foreign or user-created files in the log directory, log names changed across app versions, or files like 'service.log' sitting alongside dated logs.
