I'm not an expert on this, and I hope I don't get anything wrong here. There are two versions of App Engine: flexible and standard. In the flexible environment you can import any package and write Go code in the normal way; your program will run in a Docker container. In the standard environment you can import any package other than unsafe. But in the standard environment operations that make direct system calls or modify the file system will fail with an error; you have to use the App Engine APIs for those operations. There is a general description at https://cloud.google.com/appengine/docs/standard/go/runtime . I don't know if there is a specific list of operations that are not supported.
