cmd/go: unable to run go commands from within another GOROOT #30756
Description
First off: This is a weird issue. I acknowledge that. But it messes with my personal workflow, so I'm curious whether it can be satisfactorily resolved.
Reproduce:
- Clone toolchain to
.../a; run.../a/make.bash - Ditto in
.../b cd .../b/src- Execute
.../a/bin/go test bytes
Result:
go: reserved module path std not allow outside of GOROOT/src
There are three things going on here:
- Grammatical error in error message.
- Mysterious error message; it took me a while to realize the problem.
- I don't see why this no longer works. Why must this be an error?
For context: When working on the compiler, I generally hang out in GOROOT/src. I use compilecmp to generate built toolchains with different versions. Then I refer to those versions by absolute path to run benchmarks.
This also sometimes happens under the hood. I already had to fix compilecmp because it could not be run from GOROOT/src because of the same issue.
It's an annoyance to have to cd around to run benchmarks, take care with what dir you're piping results to, etc.
