: NO-ISSUE: Migrate away from deprecated ioutil

[sebrandon1]

ioutil has been deprecated since Go 1.16: https://go.dev/doc/go1.16#ioutil

Tracking issue: redhat-best-practices-for-k8s/telco-bot#52

Migration from ioutil to os for file and directory operations:

• Replaced ioutil.ReadFile with os.ReadFile and ioutil.ReadDir with os.ReadDir in core configuration and bundle loading logic, such as in pkg/profiling/config/config.go and staging/api/pkg/manifests/bundleloader.go. [1] [2] [3] [4]

• Updated validation and testing files to use os.ReadFile instead of ioutil.ReadFile, including files like staging/api/pkg/validation/internal/community.go, crd_test.go, csv_test.go, object_test.go, and operatorgroup_test.go. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10]

• Updated additional internal and registry logic to use os.ReadFile, os.WriteFile, and os.MkdirTemp in place of their ioutil counterparts, such as in operatorhub.go, buildahregistry/_options.go, and provisioner_kind.go. [1] [2] [3] [4] [5] [6]

@sebrandon1 thanks so much for this!

Unfortunately, the changes done under the staging directory need to happen upstream first and then get downstreamed.
I've created two PRs:

• Migrate away from ioutil operator-framework/api#463
• Migrate away from ioutil operator-framework/operator-registry#1865

that bring your proposed changes to the upstream components.

Could you please revert the changes under staging and just check in the pkg/profiling/config changes?

@sebrandon1 please consider rebasing this change to fix issues in the pkg directory.
