go/types: in TestStdlib, import from source instead of export data TestStdlib was failing after running rm -r $(go env GOROOT)/pkg/*/cmd as the builders do when building binary releases.¹ For users who write programs that depend on go/types, it should be reasonable to run the tests for go/types as part of 'go test all', and those tests should pass even if they installed Go from a binary release. I had originally drafted this as a fallback to import from source only if the affected packages can't be imported by the default export-data importer. Unfortunately, I realized that we don't currently have a builder that tests the actual release (#46900), so it is quite likely that the fallback path would bit-rot and produce unexpected test regressions. So instead, we now unconditionally import from source in TestStdlib. That makes the test substantially slower (~15s instead of ~5s on my workstation), but with less risk of regression, and TestStdlib is skipped in short mode already so short-mode test time is unaffected. If we change the builders to test the actual release configuration, we can consider restoring the faster path when export data is available. ¹https://github.com/golang/build/blob/df58bbac082bc87c4a3cdfe336d1ffe60bbaa916/cmd/release/release.go#L533-L545 For #43232 Change-Id: I764ec56926c104053bb2ef23cf258c8f0f773290 Reviewed-on: https://go-review.googlesource.com/c/go/+/330252 Trust: Bryan C.
