Note that this assumes that both (docker login) and (oc login) has
happened, the credentials can be read from the usual config files,
and that the default OpenShift instance should be used.
This includes copy&pasted/modified/simplified code from OpenShift
and Kubernetes, primarily for config file parsing and setting up
TLS and HTTP authentication.
This is much smaller than linking to the upstream OpenShift client
libraries, which via various abstractions and registration drag in much
(dozens of megabytes) more code.
The primary loss from this simplification is automatic conversions
between various versions of the API objects, both for the REST API and
for local configuration storage.
This does not contain downloading/uploading signatures, which depends on
server-side support.
Set GOPATH to start with ./vendor so that we use the dependencies in our
vendored versions instead of dependencies in whatever other version is
elsewhere in GOPATH.
And then undo it when trying to list the non-vendor subpackages in the
current directory.
github.com/coreos/etcd as of v2.2.5 uses a Godeps subdirectory, and
imports packages by including the Godeps path fragments directly in the
package name; so we can't just remove the subdirectory and vendor the
included package directly. So, add a flag to clone() to surpress
removing the vendor subdirectories.
Instead of only checking dependencies of the "main" packages, include
also test dependencies of all subpackages of the project, and their
transitive dependencies.
Otherwise the "clean" step of hack/vendor.sh would drop most .go files
from vendor/ as unused.
Also commits refreshed versions of a few of the vendored packages.
Validating only committed files is not useful in the natural
$test_everything_passes; commit; push
workflow; the failures will not be caught locally, only by Travis later
(and only if PRs are used instead of direct commits to master).
So, use the working directory state instead of last commit for
validations; and remove misleading comments in checks which already use
the working directory state.
