.. that are not migrated to CSI in 1.26 *and* are based on a block device.
NFS and CephFS may use the same volume as several PVs and then mounting
with -o context won't work.
This was originally added in the early days of go.mod in order to ensure that the root k8s.io/kubernetes
go.mod file reflected all the versions of dependencies we were using, and to ensure that go commands didn't spuriously
increment these versions.
With module pruning in go1.17+ and go defaulting to mod=readonly mode in go1.16+, this is no longer necessary.
Some of our API types contain fields that get rendered very poorly by
gomega.format.Object because they contain lots of internal information, for
example CreationTimestamp. As a result, dumping full API object typically gets
truncated.
What we want is a representation that is a) multi-line (in contrast to the
stringer implemented by our types) and b) drops empty fields where it
was defined that this is okay.
The normal YAML representation fits that requirement. We just need to teach
gomega how and when to do that. This cannot be done for each type through a
generated GomegaString method (lots of code, additional dependency in public
API on YAML encoder), but it can be done inside tests by adding a formatting
handler (new gomega feature).
Our tooling cannot handle very long failure messages well:
- when unfolding a test in the spyglass UI, it fills the entire screen
- failure correlation for http://go.k8s.io/triage has resource constraints
We cannot enforce that all tests only produce short failure messages and even
if we could, depending on the test failure, including more information may be
useful to understand it.
To achieve both goals (summary for correlation and overview, all details
available when digging deeper), too longer failure messages now get truncated,
with the full message guaranteed to be captured in the test output.
"Too long" is arbitrarily chosen to be similar to the gomega.MaxLength because
that has been a limit for failure message size in the past.
When gomega.format exceeds the default size of 4000, it truncates and prints:
Gomega truncated this representation as it exceeds 'format.MaxLength'.
Consider having the object provide a custom 'GomegaStringer' representation
or adjust the parameters in Gomega's 'format' package.

These instructions don't help the user of the e2e.test binary unless we provide
a command line flag.
Gomega adds support for formatting extensions and StopTrying in matchers.
Ginkgo enhances DeferCleanup.
This also triggered an update of other dependencies.
The Desired State of World can require a different SELinux mount context than
is in the Actual State of World and it's perfectly OK. For example when
user changes SELinux context of Pods or when the context is reconstructed
after kubelet restart.
Don't spam log and don't report errors to the user as event - reconciler
will do the right thing and unmount the old volume (with wrong context) and
mount a new one in the next reconciliation. It's not an error, it's
expected workflow.
