Init calls in the Golang package

This is a created article in which the information may have evolved or changed.

Multiple init functions can exist in a package

Bloggers are not responsible, 3 should be each init will be called, and the order is fixed

1. The init () call order for the same go file is from top to bottom
2. For different files in the same package, the Init () function in each file is called from small to large by the file name string, for
3, for different packages, if not interdependent, according to the main package "import first Call" in order to call the Init () in its package
4. If the package has dependencies, first call Init () in the first dependent package
This order is at least valid for Golang 1.1.2 (tested by my own programming)
