PX4开发指南-15.3.维护

Maintenance notes

• 这个页面选择并描述了一些工具来帮助分析代码库的状态并支持其维护。

• Analyze churn

• The amount of churn, so the number of changes done to a file can be an indicator which files/parts might need refactoring.

• To find churn metrics a tool such as Churn can be used:

gem install churn

• An example output as of v1.6.0-rc2 would be:

cd src/Firmware
churn --start_date "6 months ago"
