Previously, we were never obfuscating runtime and its direct
dependencies. Unfortunately, due to linkname, the runtime package is
actually closely related to dozens of other std packages as well.
Until we can obfuscate the runtime and properly support go:linkname
directives, obfuscating fewer std packages is a better outcome than
breaking and not producing any obfuscated code at all.
The added test case is building runtime/pprof, which used to cause
failures:
# runtime/pprof
/go/src/runtime/pprof/label.go:27:21: undefined: context.Context
/go/src/runtime/pprof/label.go:59:21: undefined: context.Context
/go/src/runtime/pprof/label.go:93:16: undefined: context.Context
/go/src/runtime/pprof/label.go:101:20: undefined: context.Context
The net package was also very close to obfuscating properly thanks to
this change, so its test is now run as well. The only other remaining
fix was to not obfuscate fields on cgo types, since those aren't
obfuscated at the moment.
The map is pretty long, but it's only a temporary solution and the
command to obtain the list again is included. Never obfuscating the
entire std library is also an option, but it's a bit unnecessary.
Fixes#134.
Previously garble heavily used env vars to share data between processes.
This also makes it easy to share complex data between processes.
The complexity of main.go is considerably reduced.
