What did you do?

% mkdir -p $GOPATH/src/p
% cd $GOPATH/src/p
% go test .
stat /var/folders/lv/028ssy8n19v56_k2q43kkb5r0000gn/T/: no such file or directory

What did you expect to see?

% go test .
can't load package: package d: no buildable Go source files in /home/dfc/src/p

What did you see instead?

% go test .
stat /var/folders/lv/028ssy8n19v56_k2q43kkb5r0000gn/T/: no such file or directory

Note: go1.8rc3 returns

% go test .
can't load package: package p: no buildable Go source files in /Users/dfc/src/p

Sorry for the noise, after flicking the build rev back and forth a few times I can no longer reproduce the issue

This is very confusing. The same command entered with a delay, fails the first time, then works the second

zapf(~/src/github.com/travisjeffery/jocko) % go test
stat /var/folders/lv/028ssy8n19v56_k2q43kkb5r0000gn/T/: no such file or directory

// a minute passes

zapf(~/src/github.com/travisjeffery/jocko) % go test
can't load package: package github.com/travisjeffery/jocko: no buildable Go source files in /Users/dfc/src/github.com/travisjeffery/jocko

It's important to note that a small amount of time passes before running the command a second time. Even though no other process is run, the problem appears to fix itself.

I'm going to close this issue, I think it's a problem with this machine.

Sorry for the noise, it turned out to be a badly written test

travisjeffery/jocko#24

On linux this would be a noon as /tmp us usually not owned by the user, but on OSX $TMP is a subdirectory of a larger temporary directory created on login.
