关键摘要:

• 在SyncFileInfoPrivate::updateFileType()函数中，移除了对fileMode的赋值操作，可能会影响后续代码逻辑。需要确认这一改动是否符合预期。
• 在BasicWidget::basicFill()函数中，增加了对fileCalculationUtils的连接操作，但没有相应的注释说明连接的目的和作用。

是否建议立即修改:

• 是，需要确认SyncFileInfoPrivate::updateFileType()函数中移除fileMode赋值操作的合理性，并添加必要的注释。
• 是，建议添加注释来解释fileCalculationUtils连接操作的目的和作用，以便其他开发者理解代码的意图。
