The alias for vendor/github.com/onsi/ginkgo/ginkgo ensures that code like
30e99cb2a9/experiment/kind-conformance-image-e2e.sh (L110)
continues to work. The one without "vendor/" is there just in case that it
was used because it also worked.
Long term, "ginkgo" is a nicer, version independent alias. It gets used
internally to avoid future churn and gets documented also publicly in the
Makefile help.
The caveat is that there's no guarantee that a future v3 CLI will be compatible
with current invocations. But the most common usage is through
hack/ginkgo-e2e.sh, which can deal with such differences.
- update all the import statements
- run hack/pin-dependency.sh to change pinned dependency versions
- run hack/update-vendor.sh to update go.mod files and the vendor directory
- update the method signatures for custom reporters

This commit cleans up references to the old kubernetes-node-e2e-images
project. In the process it removes the `LIST_IMAGES` mode as listing
large numbers of public cloud projects is not particularly useful, and
has been somewhat broken for a long period of time - as we defaulted
launching a VM to a different project than listing.
Make's "define" feature (macros) is subtle and it took me a long time to
convince myself this all works. In particular, we (prior to this commit)
are terribly inconsistent about the use of `$` vs `$$`. We mostly get
away with it because the "variables" are more like "constants", but the
inconsistency trips up some things. For example, using `$(shell)`
inside a macro will run at macro expansion time rather than when the
resulting make code is executed.
For a contrived, but concrete example, derived from our Makefile:
```
define MACRO
ifeq ($(DBG),1)
$(warning dbg is $(DBG))
endif
endef # macro
TGTS=a b c
$(foreach pfx, $(TGTS), $(eval $(MACRO)))
default:
@echo $@
```
yields:
```
$ make
Makefile:8: dbg is
Makefile:8: dbg is
Makefile:8: dbg is
default
$ make DBG=1
Makefile:8: dbg is 1
Makefile:8: dbg is 1
Makefile:8: dbg is 1
default
```
This is because `$(warning)` is evaluated as the macro is expanded.
Replace that with `$(shell)` and you can see how you might end up
running a bunch of things you didn't need to run. The fix is:
```
define MACRO
ifeq ($(DBG),1)
$$(warning dbg is $$(DBG))
endif
endef # macro
TGTS=a b c
$(foreach pfx, $(TGTS), $(eval $(MACRO)))
default:
@echo $@
```
which yields:
```
$ make
default
$ make DBG=1
Makefile:8: dbg is 1
Makefile:8: dbg is 1
Makefile:8: dbg is 1
default
```
We COULD have only changed `$(warning)` to `$$(warning)` and left
`$(DBG)` alone, because that's a cheap expansion. I chose NOT to do
that here because it requires brainpower to think about this all, and it
seems easier to set a simple rule: inside a `define`/`endef` block, you
always use `$$` unless you KNOW that you NEED expansion-time evaluation
(as in the `$(prefix)` in this commit, which is effectively an argument
to the macros).
