getting task info: %w

Error message

getting task info: %w

What it means

Get wraps any non-ErrNoRows error from the tasks-table SELECT with 'getting task info: %w'. Unlike the not-found case, this signals a database-level failure while reading status, message, and attempt for the given task ID.

Solutions

1. Read the wrapped inner error to pinpoint the cause (I/O error, lock, schema, context).
2. Confirm the data directory is accessible and not opened by another process.
3. If the schema changed between versions, back up and remove/rename the old database file so it is recreated.
4. Retry with a fresh or longer-lived context if the error is context cancellation or a transient lock.

info, err := q.Get(ctx, taskID)
if err != nil {
    if errors.Is(err, context.Canceled) || ctx.Err() != nil {
        return retryGet(taskID)
    }
    if strings.Contains(err.Error(), "not found") {
        return nil // not-found is a separate, expected path
    }
    return fmt.Errorf("DB read failed: %w", err)
}

When it happens

Trigger: QueryRowContext fails for reasons other than no rows: the SQLite database is locked/corrupt, the context was cancelled mid-query, the tasks table schema is incompatible (missing columns after a version change), or the DB file is unreadable.

Common situations: A second process holding a write lock on the DB; corrupt database from a hard crash; querying a data directory created by an older plugin version whose tasks table lacks new columns; caller cancelling the context during polling loops.
