Daniel Martí 511779d8ff testdata: set GOPRIVATE in all but two tests (#104)
basic.txt just builds main.go without a module. Similarly, we leave
imports.txt without a GOPRIVATE, to test the 'go list -m' fallback.

For all other tests, explicitly set GOPRIVATE, to avoid two exec calls -
both 'go env GOPRIVATE' as well as 'go list -m'. Each of those calls
takes in the order of 10ms, so saving ~26 exec calls should easily add
to 200-300ms saved from 'go test -short'.

lu4p 7df14ad860 Fix reflect detection if -literals is passed.
Fixes #93.

The second typecheck lead to the creation of different type objects,
which didn't match the types in the blacklist anymore.

It turns out we don't need the second typecheck,
therfore it is now removed.

Daniel Martí d0e01478f0 keep build flags when calling 'go list'
Otherwise any build flags like -tags won't be used, and we might easily
end up with errors or incorrect packages.

The common case with -tags is covered by one of the integration test
scripts. On top of that, we add a table-driven unit test to cover all
edge cases, since there are many we can do quickly in a unit test.

Fixes #82.

Daniel Martí 80538f19c7 blacklist struct fields with reflection too
In the added test, the unexported field used to be garbled.

Reflection can only reach exported methods, exported fields, and
unexported fields. Exported methods and fields are currently never
garbled, so unexported fields was the only missing piece.

exclude identifiers used via reflection
If reflect.TypeOf or reflect.ValueOf are used on a type declared in the same package,
don't garble that type name or any of its fields.

Fixes #15.

Daniel Martí 19e4c098cd make selection of packages configurable via GOPRIVATE
Carefully select a default that will do the right thing when inside a
module, as well as when building ad-hoc packages.

This means we no longer need to look at the compiler's -std flag, which
is nice.

Also replace foo.com/ with test/, as per golang/go#37641.

Fixes #7.

Daniel Martí 5aaa086e5d don't remove "//go:" compile directives
For example, this broke cgo, since it uses go:linkname.

Daniel Martí d72c00eafd support building modules which require other modules
We use 'go list -json -export' to locate required modules. This works
fine to locate direct module dependencies; since we're building in the
current module, we run 'go list' in the correct directory.

However, if we're building one of those module dependencies, and it has
other module dependencies of its own, we would fail with cryptic errors
like:

	typecheck error: [...] go list error: updates to go.sum needed, disabled by -mod=readonly

This is because we would try to run 'go list' outside of the main
module, probably inside the module cache. Instead, use a $GARBLE_DIR env
var from the top-level 'garble build' call to always run 'go list' in
the original directory.

We add a few small modules to properly test this.

Updates #9.

Daniel Martí 302cc137b6 test that filenames are garbled
We've done this for a while, but we weren't testing it.

Daniel Martí 308e984293 don't use regexes when searching binaries for strings
This is a bit simpler, and saves us a small amount of CPU work in the
tests.

Daniel Martí 30524ea282 shorten 'go test -short' run time
Down from ~11s to ~7s, as we can skip some extra checks.

While at it, avoid duplicate 'go test' builds in test.txt.

Daniel Martí e08dd99c1e introduce a binary grep command for the tests
The problem with the "grep" built-in command is that it prints the
entire data if there is an error. We don't want megabytes of binary
output for a test.
