I was trying to use goweb (https://github.com/stretchrcom/goweb) on app-engine (1.1). I also have a go 1.1 installation.
I was surprised to get this error on the browser and terminal:
The Go application could not be built.
/home/jlvazquez/goprojects/src/github.com/stretchrcom/goweb/paths/path.go:74: undefined: "strings".TrimPrefix
Investigating, it seems that appengine's strings package is NOT the same as the normal go 1.1 strings package or the one on the web. For instance, TrimPrefix does NOT exist on appengine.
Why is this happening?
I believe that this is not a sandboxing question, the strings' function trimPrefix is quite a basic one to be "forbiden" (it does not make any sense to filter it out)
