All wrappers except for ExpectNoError are identical to their gomega
counterparts. The only advantage that they have is that their invocations are
shorter.
That advantage does not outweigh their disadvantages:
- cannot be used in combination with gomega.Eventually/Consistently
- not a full replacement for gomega, so we just end up using both
- don't support passing a stack offset and thus cannot be used in helper
functions
- ginkgolinter does not work for them, so sub-optimal calls like this one
are not reported:
framework.ExpectEqual(len(items), 0)
->
gomega.Expect(items).To(gomega.BeEmpty())
- developers try to make do with what's available in the framework, leading
to sub-optimal checks like this:
framework.ExpectEqual(true, strings.Contains(event.Message, expectedEventError), "Event error should indicate non-root policy caused container to not start")
->
gomega.Expect(event.Message).To(gomega.ContainSubstring(expectedEventError), "Event error should indicate non-root policy caused container to not start")
So let's remove these wrappers. As a first step they get marked as deprecated.
This enables stricter
linting (https://github.com/kubernetes/kubernetes/pull/109728), once enabled,
to report new code which uses them.
All of these issues were reported by https://github.com/nunnatsa/ginkgolinter.
Fixing these issues is useful (several expressions get simpler, using
framework.ExpectNoError is better because it has additional support for
failures) and a necessary step for enabling that linter in our golangci-lint
invocation.

Fix the waiting logic in the e2e test loop to wait
for resources to be reported again instead of making logic on the
timestamp. The idea is that waiting for resource availability
is the canonical way clients should observe the desired state,
and it should also be more robust than comparing timestamps,
especially on CI environments.

The podresources e2e tests want to exercise the case on which a device
plugin doesn't report topology affinity. The only known device plugin
which had this requirement and didn't depend on specialized hardware
was the kubevirt device plugin, which was however deprecated after
we started using it.
So the e2e tests are now broken, and in any case they can't depend on
unmaintained and liable to be obsolete code.
To unblock the state and preserve some e2e signal, we switch to the
sample device plugin, which is a stub implementation and which is
managed in-tree, so we can maintain it and ensure it fits the e2e test
usecase.
This is however a regression, because e2e tests should try their hardest
to use real devices and avoid any mocking or faking.
The upside is that using a OS-neutral device plugin for the tests enables
us to run on all the supported platform (windows!) so this could allow
us to transition these tests to conformance.

The check for "resources available on a node" must treat nodes that are not
listed as "no resources available". The previous logic only worked because all
nodes were listed during E2E testing. The upcoming integration testing is
covering additional scenarios and triggered this broken case.
It provides more readable output and has additional APIs for using it inside a
unit test. goleak.IgnoreCurrent is needed to filter out the goroutine that gets
started when importing go.opencensus.io/stats/view.
In order to handle background goroutines that get created on demand and cannot
be stopped (like the one for LogzHealth), a helper function ensures that those
are running before calling goleak.IgnoreCurrent. Keeping those goroutines
running is not a problem and thus not worth the effort of adding new APIs to
stop them.
Other goroutines are genuine leaks for which no fix is available. Those get
suppressed via IgnoreTopFunction, which works as long as that function
is unique enough.
Example output for the leak fixed in https://github.com/kubernetes/kubernetes/pull/115423:

- test/e2e/framework/*.go should have very minimal dependencies.
We can enforce that via import-boss.
- What each test/e2e/framework/* sub-package uses is less relevant,
although ideally it also should be as minimal as possible in each case.
Enforcing this via import-boss ensures that new dependencies get flagged as
problem and thus will get additional scrutiny. It might be okay to add them,
but it needs to be considered.

The previous approach was based on the observation that some Prow jobs use the
--report-dir parameter instead of the E2E_REPORT_DIR env variable. Parsing the
command line was necessary to use the --json-report and --junit-report
parameters.
But that is complex and can be avoided by triggering the creation of complete
reports in the E2E test suite. The paths are hard-coded and relative to the
report directory to keep the code simple.
There was a report that k8s-triage started processing more data after
6db4b741dd was merged. It's unclear whether
that was because of the new <report-dir>/ginkgo_report.xml file. To avoid
this potential problem, the reports are now in a "ginkgo" sub-directory.
While at it, error checking gets enhanced:
- Create directories at the start of
the suite and bail out early if that fails.
- *All* e2e suites using the framework do this, not just test/e2e.
- Added missing error checking of truncated JUnit report writing.
Currently `kubectl debug` only supports passing names in command line.
However, users might want to pass resources in files by passing `-f` flag like
in all other kubectl commands.
This PR adds this ability.
With the change of the CRI-O jobs to use butane, we now have a
verification for base64 data urls in place. This means that the
following URL is invalid:
```

```
This means we have to pass valid base64 to the URL. To fix that, we now
allow to inject SSH key values with both, the
`GCE_SSH_PUBLIC_KEY_FILE_CONTENT` field and its base64 encoded variant.

The NPD test checks when NPD started to determine if it is needed to
check the kubelet start event. The current logic requires parsing the
journalctl logs which is quite fragile and is broken now because of
systemd changing the expected log format.
Newer versions of systemd do not print "end at" or "logs begin at" and
instead may print "No entries", which will result in the test panicking.
```
$ journalctl -u foo.service
-- No entries --
```
For units started, it will not print "end at" or "logs begin at":
```
root@ubuntu-jammy:~# journalctl -u foo.service
Feb 08 22:02:19 ubuntu-jammy systemd[1]: Started /usr/bin/sleep 1s.
Feb 08 22:02:20 ubuntu-jammy systemd[1]: foo.service: Deactivated successfully.
```
To avoid relying on log parsing which is fragile, let's instead directly
ask systemd when the NPD service started and parse the resulting
timestamp.

There is a test in wait.sh integration suite which is checking the
given timeout value(passed by user) is equal to actual happened timeout value.
However, this test rarely gets `no matching resources found` error and
causes flakyiness. The reason is we are running wait command, immediately
after applying deployment. In reality, timeout test does not care about
deployment, since it is testing the timeout by passing invalid configurations.
But we need this deployment to not get `no matching resources found` error.
That's why, this PR adds deployment assertion before executing wait command.
The recently introduced failure handling in ExpectNoError depends on error
wrapping: if an error prefix gets added with `fmt.Errorf("foo: %v", err)`, then
ExpectNoError cannot detect that the root cause is an assertion failure and
then will add another useless "unexpected error" prefix and will not dump the
additional failure information (currently the backtrace inside the E2E
framework).
Instead of manually deciding on a case-by-case basis where %w is needed, all
error wrapping was updated automatically with
sed -i "s/fmt.Errorf\(.*\): '*\(%s\|%v\)'*\",\(.* err)\)/fmt.Errorf\1: %w\",\3/" $(git grep -l 'fmt.Errorf' test/e2e*)
This may be unnecessary in some cases, but it's not wrong.
Instead of pod responses being printed to the log each time polling fails, we
get a consolidated failure message with all unexpected pod responses if (and
only if) the check times out or a progress report gets produced.
This renames PodsResponding to WaitForPodsResponding for the sake of
consistency and adds a timeout parameter. That is necessary because some other
users of NewProxyResponseChecker used a much lower timeout (2min vs. 15min).
Besides simplifying some code, it also makes it easier to rewrite
ProxyResponseChecker because it only gets used in WaitForPodsResponding.
WaitForPodToDisappear was always called such that it listed all pods, which
made it less efficient than trying to get just the one pod it was checking for.
Being able to customize the poll interval in practice wasn't useful, therefore
it can be replaced with WaitForPodNotFoundInNamespace.
WaitForPods is now a generic function which lists pods and then checks the pods
that it found against some provided condition. A parameter determines how many
pods must be found resp. match the condition for the check to succeed.
The code becomes simpler (78 insertions, 91 deletions), easier to read (all
code entirely inside WaitForPodsRunningReady, no need to declare and later
overwrite variables) and possibly more correct (if all API calls failed,
the resulting error was ignored when allowedNotReadyPods > 0).
None of the users of the functions passed anything other than nil or an empty
map and the implementation ignore the parameter - it seems like a candidate for
simplification.
When a Gomega failure is converted to an error, the stack at the time when the
failure occurs may be useful: error wrapping provides some bread crumbs that
can be followed to determine where the failure really occurred, but error
wrapping may be missing or ambiguous.
To provide the additional information, a FailureError now includes a full stack
backtrace. The backtrace intentionally makes no attempt to exclude framework
functions besides the gomega support itself because helpers like
e2e/framework/pod may be relevant.
That backtrace is not included in the failure message for the sake of
brevity. Instead, it gets logged as part of the test's output.
gomega.Eventually provides better progress reports: instead of filling up the
log with rather useless one-line messages that are not enough to to understand
the current state, it integrates with Gingko's progress reporting (SIGUSR1,
--poll-progress-after) and then dumps the same complete failure message as
after a timeout. That makes it possible to understand why progress isn't
getting made without having to wait for the timeout.
The other advantage is that the failure message for some unexpected pod state
becomes more readable: instead of encapsulating it as "observed object" inside
an error, it directly gets rendered by gomega.
Calling gomega.Expect/Eventually/Consistently deep inside a helper call chain
has several challenges:
- the stack offset must be tracked correctly, otherwise the callstack
for the failure starts at some helper code, which is often not informative
- augmenting the failure message with additional information from each
caller implies that each caller must pass down a string and/or format
string plus arguments
Both challenges can be solved by returning errors:
- the stacktrace is taken at that level where the error is
treated as a failure instead of passing back an error, i.e.
inside the It callback
- traditional error wrapping can add additional information, if
desirable
What was missing was some easy way to generate an error via a gomega
assertion. The new infrastructure achieves that by mirroring the
Gomega/Assertion/AsyncAssertion interfaces with errors as return values instead
of calling a fail handler.
It is intentionally less flexible than the gomega APIs:
- A context must be passed to Eventually/Consistently as first
parameter because that is needed for proper timeout handling.
- No additional text can be added to the failure through this
API because error wrapping is meant to be used for this.
- No need to adjust the callstack offset because no backtrace
is recorded when a failure occurs.
To avoid the useless "unexpected error" log message when passing back a gomega
failure, ExpectNoError gets extended to recognize such errors and then skips
the logging.
Calling WaitForPodTerminatedInNamespace after testFlexVolume is useless because
the client pod that it waits for always gets deleted by testVolumeClient:
0fcc3dbd55/test/e2e/framework/volume/fixtures.go (L541-L546)
Worse, because WaitForPodTerminatedInNamespace treats "not found" as "must keep
polling", these two tests always kept waiting for 5 minutes:
Kubernetes e2e suite: [It] [sig-storage] Flexvolumes should be mountable
when non-attachable 6m4s
The only reason why these tests passed is that WaitForPodTerminatedInNamespace
used to return the "not found" API error. That is not guaranteed and about to
change.
Unknown pods are pods which are unknown pods to the kubelet, but are still
running in the container runtime. If kubelet detects a pod which is not in
the config (i.e. not present in API-server or static pod), but running as
detected in container runtime, kubelet should aggressively terminate the pod.
This situation can be encountered if a pod is running, then kubelet is
stopped, and while stopped, the manifest is deleted (by force deleting the
API pod or deleting the static pod manifest), and then restarting the
kubelet. Upon restart, kubelet will see the pod as running via the container
runtime, but it will not be present in the config, thus making the pod a
"unknown pod". Kubelet should then proceed to terminate these unknown pods.
Add two tests that ensure that unknown pods will be terminated (1)
static pods and (2) API pods. The test will start a pod, stop the
kubelet, force delete the pod (by deleting the manifest or force
deleting the pod), and then restarting the kubelet. The container
runtime is then queried to ensure the containers are terminated by
kubelet.

The device plugin test expects that no other pods are running prior to
the test starting. However, it has been observed that in some cases
some resources may still be around from previous tests. This is because
the deletion of resources from other tests is handled by deleting that
test's framework's namespace which is done asynchronously without
waiting for the other test's namespace to be deleted.
As a result, when the node e2e device plugin starts, there may still be
other pods in process of termination. To work around this, add a retry
to the device plugin test to account for the time it takes to delete the
resources from the prior test.

PVCs using the ReadWriteOncePod access mode can only be referenced by a
single pod. When a pod is scheduled that uses a ReadWriteOncePod PVC,
return "Unschedulable" if the PVC is already in-use in the cluster.
To support preemption, the "VolumeRestrictions" scheduler plugin
computes cycle state during the PreFilter phase. This cycle state
contains the number of references to the ReadWriteOncePod PVCs used by
the pod-to-be-scheduled.
During scheduler simulation (AddPod and RemovePod), we add and remove
reference counts from the cycle state if they use any of these
ReadWriteOncePod PVCs.
In the Filter phase, the scheduler checks if there are any PVC reference
conflicts, and returns "Unschedulable" if there is a conflict.
This is a required feature for the ReadWriteOncePod beta. See for more context:

The ClusterIP allocator tries to reserve on part of the ServiceCIDR
to allocate static IPs to the Services.
The heuristic of the allocator to obtain the offset was taking into
account the whole range size, not the IPs available in the range, the
subnet address and the broadcast address for IPv4 are not available.
This caused that for CIDRs with 16 hosts, /28 for IPv4 and /124 for
IPv6, the offset calculated was higher than the max number of available
addresses on the allocator, causing this to panic.

There are two runtime class tests which required the container runtime
config to include explicit configuration for `test-handler`. The current
logic skips these tests in non GCE environments. This skip is too strict
since the test is skipped in node e2e environments and in other
environments such as kind, which support running the test and also
configure `test-handler`.
Instead of skipping based on provider, add a new function
`NodeSupportsPreconfiguredRuntimeClassHandler` which examines the
underlying container runtime config and checks if the config includes
`test-handler`. The check is a bit brittle since it assumes container
runtime config paths, but it is a net improvement over skipping the test
entirely on non GCE environments.
This results in the test working in the common test environments, namely
GCE kube-up, node e2e, and kind.
