ParseBoolerror breaks Reconcile whenfeature.compliance_tagsis missing.
strconv.ParseBool("")returns an error, and the caller at lines 148-151 surfaces this error fromReconcile, failing the entire reconciliation. Existing deployments whose default ConfigMap predates the newfeature.compliance_tagskey will now go into an unrecoverable error loop.Beyond that, the log message immediately above (
"... - compliance tagging is disabled") tells the operator the feature was gracefully disabled, which is inconsistent with returning an error that aborts reconciliation. The previous behavior (per the PR summary) was to continue without failing — that is the correct semantic here, sincecompliance_tagsis an optional feature gate.🛠️ Proposed fix

controllers/account/account_controller_test.goline 1325 was updated to setfeature.compliance_tags: "false"explicitly, which masks this regression in tests.

Inline comments:
In `@controllers/account/account_controller_test.go`:
- Around line 1324-1330: The test ConfigMap in
controllers/account/account_controller_test.go currently sets
"feature.compliance_tags": "false", which masks a regression in
generateAccountTags by preventing the missing-key code path from being
exercised; remove that "feature.compliance_tags" entry from the test's map so
tests cover the case where the key is absent (ensuring generateAccountTags
returns nil for missing-key scenarios) and leave a comment if you want to keep
it as documentation.
In `@controllers/validation/account_validation_controller_test.go`:
- Around line 416-424: The test dereferences validationErr after errors.As could
fail in the ValidateAccountOrigin() test; update the test so that after the
errors.As check on err into validationErr (using errors.As(err,
&validationErr)), you immediately fail/return/continue when it returns false to
avoid nil dereference, then proceed to assert validationErr.Type ==
InvalidAccount and validationErr.Err.Error() == tt.expectedErr; ensure
references to ValidateAccountOrigin(), AccountValidationError, validationErr,
and tt.expectedErr are used so the fix is applied to the correct assertions.
- Around line 573-584: The test currently calls errors.As(err, &validationErr)
but proceeds to dereference validationErr even when errors.As returned false;
update the ValidateAccountTags() test so that after the errors.As check fails
you immediately call t.Fatalf or return (e.g., t.Fatalf("expected
AccountValidationError, got %v", err)) to stop further execution, ensuring
validationErr is only accessed when errors.As succeeds; keep references to
AccountValidationError, errors.As, validationErr, and the enum values
MissingTag, IncorrectOwnerTag, AccountTagFailed so the subsequent message checks
remain unchanged.
In `@pkg/totalaccountwatcher/totalaccountwatcher.go`:
- Around line 105-106: The break inside the select when handling stopCh.Done()
is ineffective (it only exits the select, not the outer for) and should be
replaced with a return to stop the goroutine; update the handler that logs
"Stopping the totalAccountWatcher" in the for-select loop in totalAccountWatcher
(pkg/totalaccountwatcher, function totalAccountWatcher or the method containing
stopCh.Done()) to return after logging instead of using the //nolint and break
so the watcher actually exits gracefully.
In `@pkg/utils/utils.go`:
- Around line 13-14: The import ordering and a production dependency on a test
package must be fixed: reorder imports in pkg/utils/utils.go so standard library
imports come first, then third-party packages, and only then local/project
packages (move "github.com/openshift/aws-account-operator/test/fixtures" after
third-party imports or remove it), and eliminate the use of fixtures.NotFound in
production code by defining the NotFound sentinel error in a non-test package
(e.g., create pkg/errors or pkg/constants with var NotFound = errors.New("not
found")), update pkg/utils/utils.go to import that package instead of the test
fixtures and replace fixtures.NotFound usages, and update any import statements
accordingly.

so the string comparison only happens when tt.wantErr is non-nil; update the
branch around errors.Is/errors.As and AccountValidationError to return
appropriately when tt.wantErr is nil.

Nitpick comments:
In `@controllers/account/account_controller_test.go`:
- Line 1519: The nolint directive is incorrect: replace the current
//nolint:errcheck on the single-value type assertion tmpcli.(*mock.MockClient)
with the proper linter name (//nolint:forcetypeassert) or, preferably, change
the assertion to the comma-ok form (tmpcli, ok :=
tmpcli.(\u002amock.MockClient)) and fail the test if !ok; update both
occurrences (the one assigning mockAWSClient and the one at the other reported
location) to use either the correct //nolint:forcetypeassert or the safe
comma-ok check so the linter suppression is effective or the test is explicit
about the assertion failure.
In `@pkg/utils/utils.go`:
- Line 13: The production package imports the test package fixtures and uses
fixtures.NotFound; remove that test dependency by adding a production error
constant (e.g., ErrNotFound) in pkg/utils (or a suitable production package) and
replace uses of fixtures.NotFound with that constant (specifically update the
reference at the location using fixtures.NotFound around line 129). Remove the
import "github.com/openshift/aws-account-operator/test/fixtures" from the
imports and ensure you add the new ErrNotFound = errors.New("not found")
declaration (or similar) in utils.go or a shared production errors file so
production code no longer depends on test packages.

Test ConfigMap masks the generateAccountTags regression.
Setting feature.compliance_tags: "false" here makes existing tests pass under the new error-returning behavior of generateAccountTags, but production ConfigMaps may not contain this key — see the corresponding comment on controllers/account/account_controller.go (lines 448-456). Once that function is fixed to return nil for the missing-key case, this entry can remain (it's still useful documentation) but won't be required for correctness.

to dereference validationErr even when errors.As returned false; update the
ValidateAccountTags() test so that after the errors.As check fails you
immediately call t.Fatalf or return (e.g., t.Fatalf("expected

| //nolint:staticcheck // SA4011: false positive on nil check | ||
| break |
There was a problem hiding this comment.
The break statement is ineffective and the staticcheck warning is a true positive, not a false positive.
In Go, a break statement inside a select that is itself inside a for loop only breaks from the select, not the outer for loop. When stopCh.Done() is triggered, this code logs "Stopping the totalAccountWatcher" but immediately continues the loop, preventing graceful shutdown.
The SA4011 staticcheck warning correctly identifies this bug. Suppressing it as a "false positive" is incorrect and masks a real correctness issue.
🔧 Proposed fix: Replace break with return
case <-stopCh.Done():
log.Info("Stopping the totalAccountWatcher")
- //nolint:staticcheck // SA4011: false positive on nil check
- break
+ return
}

Fix import ordering and remove production dependency on test package.
The file has two issues:
-
Import ordering violation: The
test/fixturesimport (line 13) is placed before third-party imports (lines 15-18). Go conventions group imports as: standard library → third-party packages → local/project packages. This import should move after all third-party imports. -
Production code importing test package:
pkg/utils/utils.goimportsgithub.com/openshift/aws-account-operator/test/fixturesand usesfixtures.NotFoundat line 129. Production code should not depend on test packages. Consider moving theNotFounderror definition to a production-appropriate location (e.g., a constants or errors package) and updating the reference.

Summary
This PR fixes 45 mechanical lint violations to enable CI/PROW validation. These are low-risk, automated fixes that prepare the codebase for subsequent PRs addressing context threading and complexity reduction.
This is PR1 of 4 in our systematic approach to resolving 117 total lint violations (see #987).
Changes by Category
1. Error Handling Modernization (errorlint) - 22 violations
What: Converted error handling from legacy (pre-Go 1.13) patterns to modern wrapped error handling.
Changes:
errors.Is()err.(type)) →errors.As(err, &target)%winfmt.Errorf()Why:
errors.Is()anderrors.As()properly handle wrapped errors (Go 1.13+), preventing bugs where wrapped errors aren't detected.Example:
2. Error Propagation (nilerr) - 6 violations
What: Fixed cases where errors were swallowed instead of returned.
Changes:
//nolint:nilerrwhere nil return is safety feature (config.go payer account handling)3. Error Checking in Tests (errcheck) - 4 violations
What: Added error checking in test code that was silently ignoring errors.
Changes:
GetClient()errors withExpect(err).ToNot(HaveOccurred())Why: Prevents silent test failures and nil pointer panics.
4. Exhaustive Enum Handling (exhaustive) - 11 violations
What: Added handling for all enum cases in switch statements.
Changes:
//nolint:exhaustivewhere default case handles unknownsWhy: Dev modes (Local/Cluster) should SKIP AWS support operations, not perform them.
5. Unused Parameters (unparam) - 2 fixes
What: Removed parameters that were never used in function bodies.
Changes:
getCCSClient(): Removed unusedcurrentAcctparametersetAccountFailed(): Removed unusedstateparameter (alwaysAccountFailed), removed unusedreconcile.ResultreturnWhy: Reduces maintenance burden and makes code intent clearer.
6. Pre-allocation (prealloc) - 6 optimizations
What: Pre-allocated slice capacity when final size is known.
Changes:
make([]T, 0, len(source))instead ofvar slice []TcastAWSRegionType,buildPolicyNameSlice,ValidateOptInRegions,GetIAMTags,GetEC2TagsWhy: Avoids multiple reallocations during append operations.
7. Type Conversions (unconvert) - 3 fixes
What: Removed unnecessary type conversions.
Changes:
time.Duration(time.Duration(...))double conversions8. Formatting (gofmt/goimports) - 17 files
What: Applied standard Go formatting and import ordering.
