This field is not used in the kubeadm code. It was brought from
cli-runtime where it's used to support complex relationship between
command line parameters, which is not present in kubeadm.
Change 04300826fd has introduced
"e2e/common" package dependency on volumemode testusuite. This results in
pulling all tests defined in common package while running storage e2e tests,
which are not necessary.
The only interested part from common package is the WaitTimeoutForEvent().
This patch fixes an issue in the TopologyManager that wouldn't allow
pods to be admitted if pods were launched with the SingleNUMANode policy
and any of the hint providers had no NUMA preferences.
This is due to 2 factors:
1) Any hint provider that passes back a `nil` as its hints, has its hint
automatically transformed into a single {11 true} hint before merging
2) We added a special casing for the SingleNumaNodePolicy() in the
TopologyManager that essentially turns these hints into a
{11 false} anytime a {11 true} is seen.
The current patch reworks this logic so the that TopologyManager can
tell the difference between a "don't care" hint and a true "{11 true}"
hint returned by the hint provider. Only true "{11 true}" hints will be
converted by the special casing for the SingleNumaNodePolicy(), while
"don't care" hints will not.
This is a short term fix for this issue until we do a larger refactoring
of this code for the 1.17 release.
Fix the `staticcheck` failures for `test/e2e/node`. All of the
staticcheck errors were for variables which were never used. When these
values were `err`, we added processing for the errors. When they were
values that were just never used, we stopped giving them a name.
Changes following up on shuffle sharding util package.
Made the validation checking function return a slice of error messages
rather than just a bit.
Replaced all the `int32` with `int` because this is intended for more
than just the priority-and-faireness feature and so should not be a
slave to its configuration datatypes.
Introduced ShuffleAndDealIntoHand, to make memory allocation the
caller's problem/privilege.
Made the hand uniformity tester avoid reflection, evaluate the
histogram against the expected range of counts, and run multiple test
cases, including one in which the number of hash values is a power of
two with four extra bits (as the validation check requires) and one in
which the deck size is not a power of two.
Implement several shuffle sharding functions including ShuffleAndDeal,
ShuffleAndDealToSlice.
Add benchmarks and tests for shuffle sharding to test performance,
correctness and distribution uniformity.
