日志文件不存在

Error message

日志文件不存在

What it means

ErrLogFileNotFound is returned when the requested log target does not exist under the configured log root. openValidatedLogFile returns it when the log root directory itself is absent, or when Lstat on the date directory fails with fs.ErrNotExist. It is a clean, typed "no such log" signal, distinct from unreadable (permissions) or invalid (malformed) path errors.

Solutions

1. List available dates first via the list-dates API and pick an existing one.
2. Verify the configured log output directory (GVA_CONFIG log dir) exists on the server and contains the expected date folders.
3. If logs should exist, check volume mounts / log rotation cleanup that may have deleted old files.
4. Confirm client and server agree on the day (timezones) — request the server's date.

Example fix

// before
GET /logViewer/content?date=2025-08-30&path=app.log  // ErrLogFileNotFound (no such date dir)
// after
GET /logViewer/dates?month=2025-08  // pick an existing date, then request content

dates, err := client.ListDates(ctx, month)
if err != nil { return err }
if !slices.Contains(dates, date) {
	return fmt.Errorf("no logs for %s; available: %v", date, dates)
}

content, err := client.ReadContent(ctx, date, path)
if err != nil && errors.Is(err, ErrLogFileNotFound) {
	// show "no logs for this day" in the UI; optionally fall back to the nearest earlier date
}

When it happens

Trigger: ReadContent/ListFiles for a date that has no directory under the configured log root (e.g. a day with no logs); requesting logs before the app has written any; log root misconfigured or deleted after date validation passed.

Common situations: Querying logs for today before the first write; pointing GVA log config at a custom path that was cleaned; Docker containers where logs live on an ephemeral or unmounted volume; timezone differences between client and server days.
