non blocking comments: Preserve future PodResources fields when copying. The helper constructs a new empty struct and manually copies every current field. If Velero adds another field later, this function will silently discard it until updated—particularly relevant because ephemeral-storage fields were themselves recently added. Start with result := *pr, then overwrite only empty known quantities with "0". See defaults.go lines 25–55. Add an integration regression case matching the reported failure exactly. The helper unit test covers partial fields, but the node-agent ConfigMap test uses all CPU/memory fields, while the production example uses only memoryLimit. Add a node-agent test with only memoryLimit: "100Mi" and, ideally, another with only ephemeralStorageLimit. Assert that all other serialized quantities are "0". This would catch accidental removal of the normalization call, not merely defects within the helper. |

Why the changes were made
https://redhat.atlassian.net/browse/OADP-8548
Velero datamover and maintenance Pod config the default values of "" causes parser errors. The default value has to be "0" for unbounded. If PodResources is only partially set, despite all values are optional, the result is Velero ignores them all.
As a result, a Pod with
memoryLimitorephemeralStorageLimitwill not be evicted when violated unless all values:cpuRequest,cpuLimit,memoryRequest,memoryLimit,ephemeralStorageRequest,ephemeralStorageLimitare set.This issue also applies to OADP-1.5/OADP-1.4 without the
ephemeralStorageRequestandephemeralStorageLimitfields.This includes @kaovilai requested revisions from the previous PR targeting
oadp-1.6branch.Note: Cherry-picking to OADP-1.5/OADP1.5 will require removal of defaults.go
EphemeralStorageRequestandEphemeralStorageLimitas these fields do not exist in those version.Changes since the original PR:
Added a check that DPA Spec is unchanged despite PodResources serialization may not match the DPA Spec object due to unset values -> "0" in the following modules:
How to test the changes made
Modified unit tests to account for the change that the values must be "0" on output if unset.
Built the container and tested the following DPA in OCP 4.22.

Node-agent configmap output:
.metadata.managedFields from output shown have been removed because they are annoying to read.
