If not all medium priority pods are allowed to preempt low priority pods
first the high priority pods may occupy the low priority spot and
disallow medium priority pods to preempt all low priority pods. Thus
leaving some low priority pods without a DeletionTimestamp field set and
failing the "Check all low priority pods to be about to preempted."
check.
Finalizers do not work as expected when an informer with a field
selector is used. Any time a pod changing its state gets excluded by the
field selector a synthetic delete event is issues even though the pod
with a finalizer set is still present. Thus, making the scheduler
schedule the high and medium priority pods before any of the low
priority pod finalizers is removed. Instead, rely on preStop hook and
TerminationGracePeriodSeconds to keep all low priority pods long enough
included by the field selector so all high priority pods can set their
.status.nominatedNodeName field.
Also, update the check for how many medium priority pods are expected to
be scheduled. Each node can accept 10 pods of the given extended
resources. Given there's 5 high priority created per node, there's
always 5 times number of nodes spots left for the medium priority pods.
We have "-kube-test-repo-list" command line flag to override the image registry. If we store it in global variable, then that overriding cannot take effect.
And this can cause puzzling bugs, e.g.: containerIsUnused() function will compare incorrect image address.
This changes the text registration so that tags for which the framework has a
dedicated API (features, feature gates, slow, serial, etc.) those APIs are
used.
Arbitrary, custom tags are still left in place for now.
framework.SIGDescribe is better because:
- Ginkgo uses the source code location of the test, not of the wrapper,
when reporting progress.
- Additional annotations can be passed.
To make this a drop-in replacement, framework.SIGDescribe generates a function
that can be used instead of the former SIGDescribe functions.
windows.SIGDescribe contained some additional code to ensure that tests are
skipped when not running with a suitable node OS. This gets moved into a
separate wrapper generator, to allow using framework.SIGDescribe as intended.
To ensure that all callers were modified, the windows.sigDescribe isn't
exported anymore (wasn't necessary in the first place!).
The spaces are redundant because Ginkgo will add them itself when concatenating
the different test name components. Upcoming change in the framework will
enforce that there are no such redundant spaces.

This touches cases where FromInt() is used on numeric constants, or
values which are already int32s, or int variables which are defined
close by and can be changed to int32s with little impact.

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.
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.
