A recurrence of #9767 except in that case the download happened and then go get failed to build the downloaded code. Now it's not downloading the code at all.

There is a test for this in cmd/go already but it doesn't run on builders because it needs an external network.

cmd/go: fix bug in test of go get ./path needing to download path
f0a3018 
rsc.io/toolstash is gone; use rsc.io/pprof_mac_fix.

This fixes a bug in the test. It turns out the code being tested here
is also broken, so the test still doesn't pass after this CL (filed #19769).

This bisects to CL 33158, which also caused other problems. I wonder if we should roll back that CL instead.

I didn't see this issue before. At first glance, it looks like a duplicate of issue #20175, which I was notified about and sent a fix for. I'm still waiting on your review of that CL. https://go-review.googlesource.com/c/42350/ Can you look at it first?

I've confirmed, this issue is the same as #20175, and my fix in CL 42350 fixes it too.

This is cmd/go on tip:

$ go test -v -run=TestGoGetDotSlashDownload cmd/go
=== RUN   TestGoGetDotSlashDownload
--- FAIL: TestGoGetDotSlashDownload (0.05s)
	go_test.go:310: running testgo [get ./pprof_mac_fix]
	go_test.go:323: standard error:
	go_test.go:324: can't load package: package ./pprof_mac_fix: cannot find package "./pprof_mac_fix" in:
			/var/folders/tw/kgz4v2kn4n7d7ryg5k_z3dk40000gn/T/gotest134427085/src/rsc.io/pprof_mac_fix
		
	go_test.go:333: go [get ./pprof_mac_fix] failed unexpectedly: exit status 1
FAIL
exit status 1
FAIL	cmd/go	1.701s

And this is with CL 42350:

$ go test -v -run=TestGoGetDotSlashDownload cmd/go
=== RUN   TestGoGetDotSlashDownload
--- PASS: TestGoGetDotSlashDownload (2.27s)
	go_test.go:310: running testgo [get ./pprof_mac_fix]
PASS
ok  	cmd/go	3.842s

Should we close one of the two issues as duplicate? If so, which one; this issue was earlier, but the other has more information posted in it. Or let the CL close both?

Thanks for the fix, and sorry about the delayed review. I hadn't pinged you on this because I didn't bisect it until this morning.

@rsc No problem, I'm happy to follow up and resolve any issues my work might (unintentionally) cause. Thanks!
