Because the package versions in go.mod match what we use in Godeps.json,
there are no substantive code diffs. However, there are some tiny
differences resulting from how go mod vendors things differently than
godep:
go mod does not preserve executable permissions on shell scripts
Some packages have import lines like:
package ocsp // import "golang.org/x/crypto/ocsp"
godep used to remove the comment from these lines, but go mod vendor does not.
This introduces several indirect dependencies that we didn't have
before. This is because godep used to operate at a package level, but
go mod operates at a module (~= repository) level. So if we used a
given repository, but didn't use all of its packages, we wouldn't
previously care about the transitive dependencies of the packages we
weren't using. However, in the go mod world, once we care about the
repository, we care about all of that repository's transitive
dependencies. AFAICT this doesn't affect vendoring.
Fixes#4116
Godep apparently breaks when trying to parse code that specifies build tags for versions of golang above that with which it was built (which it shouldn't be parsing in the first place). This breaks the travis tests since `golang.org/x/net/context` now contains golang 1.9 specific code. In order to get around this we temporarily disable the error check for `godep save ./...` in test.sh. Opened #2965 to revert this once Godep is fixed or we move to golang 1.9.
Requires an update to `golang.org/x/net` and adding `golang.org/x/text`.
