The docker project absurdly *copies* all of the dependencies into the
vendor/ directory instead of using git submodules or avoiding
unnecessary vendoring entirely. We manually remove these changes until
they learn to use tools how they're intended.
As an aside, we recommend using a more intelligent, modern tool like
systemd-nspawn instead.
Note: When go-grpc-prometheus was in the main $gopath (even at this
version) and everyone else was where they always were in vendor/ this
didn't build! It gave errors like:
have SendHeader("github.com/purpleidea/mgmt/vendor/google.golang.org/grpc/metadata".MD) error
want SendHeader("google.golang.org/grpc/metadata".MD) error
and I got frustrated. Putting it "next" to the other vendored deps seems
to have fixed this. Where are the golang docs that explain this
phenomenon?
This also requires golang 1.8+ as that is a requirement for etcd. It's
probably a reasonable thing for us too.
Note the older versions of etcd had some bugs with the concurrency
package and other things, so this is a necessary bump.
This was a major deadlock that hit the file resource. I didn't notice it
earlier because I was using an older version of fsnotify and I hadn't
done a go get -u to refresh it. I finally tracked this down, and will
vendor the repository until a fix upstream or a workaround downstream is
added.
The upstream issue is: https://github.com/fsnotify/fsnotify/issues/123
