- Add helper script to simplify glide usage.
- Add validation script for unwanted changes to vendoring.
- Relax/tighten up .{git,docker}ignore to cover vendored files properly.
- .validate: Protect from unbound variable in case of nounset setting.
- Install more recent hg version in the build container.
- Remove glide installation steps from Dockerfile.
- Update documentation.
validate-glide is called with errexit enabled (in script/make.sh that
sources validate-glide), which means that grep returning a non-zero exit
code will cause the script to terminate prematurely. Thus, we will never
get to the point where we see the error message.
The fix is to embed the grep check directly inside the if statement.
