cmd/go: go get panics when import path contains "cmd/something" #7638
Description
by toffaletti:
What does 'go version' print? go version go1.2.1 darwin/amd64 What steps reproduce the problem? If possible, include a link to a program on play.golang.org. I have a git repo https://github.com/toffaletti/gogetpanic that reproduces the problem. Check out the repo and run make, which is just running go get -d -t ./... after setting GOPATH. What happened? panic: runtime error: invalid memory address or nil pointer dereference [signal 0xb code=0x1 addr=0x58 pc=0x25b83] goroutine 1 [running]: runtime.panic(0x35c9e0, 0x77ff99) /usr/local/go/src/pkg/runtime/panic.c:266 +0xb6 main.downloadPackage(0xc210151c00, 0xc210085600, 0xc2100b9c01) /usr/local/go/src/cmd/go/get.go:259 +0x33 main.download(0xc2100b9c01, 0x15, 0xc210095600, 0x0) /usr/local/go/src/cmd/go/get.go:166 +0x9ea main.download(0xc2100aa320, 0x14, 0xc210095600, 0xc2100b9301) /usr/local/go/src/cmd/go/get.go:232 +0x70a main.runGet(0x77d100, 0xc21000a050, 0x1, 0x1) /usr/local/go/src/cmd/go/get.go:72 +0xc8 main.main() /usr/local/go/src/cmd/go/main.go:161 +0x4f1 goroutine 3 [syscall]: os/signal.loop() /usr/local/go/src/pkg/os/signal/signal_unix.go:21 +0x1e created by os/signal.init·1 /usr/local/go/src/pkg/os/signal/signal_unix.go:27 +0x31 make: *** [default] Error 2 What should have happened instead? go get should find the "cmd/everything/widget" import path in GOPATH or at least tell me not to have this kind of ridiculous import path instead of just panic.
