[tencent-tcr.PrepareForPush] the namespace of resource canno

Error message

[tencent-tcr.PrepareForPush] the namespace of resource cannot be null

What it means

Returned by the Tencent TCR adapter's PrepareForPush (src/pkg/reg/adapter/tencentcr/adapter.go:221) when resource.Metadata exists but resource.Metadata.Repository is nil. The adapter splits Repository.Name into namespace and repository to call createPrivateNamespace/createRepository, so a nil Repository pointer is rejected before any Tencent API call.

Solutions

1. Set Metadata.Repository with a non-empty Name for every pushed resource.
2. Run the slice-wide validation helper first to get the failing index.
3. Copy the whole Metadata (including Repository pointer) when cloning source resources.
4. Add a builder unit test asserting Repository != nil.

Example fix

// before
Metadata: &model.ResourceMetadata{Vtags: []string{"v1"}},

// after
Metadata: &model.ResourceMetadata{
    Repository: &model.Repository{Name: "myns/myrepo"},
    Vtags:     []string{"v1"},
},

for i, r := range resources {
	if r == nil || r.Metadata == nil || r.Metadata.Repository == nil {
		return fmt.Errorf("resources[%d]: missing resource/metadata/repository", i)
	}
}

func hasRepository(r *model.Resource) bool {
	return r != nil && r.Metadata != nil && r.Metadata.Repository != nil
}

if err := a.PrepareForPush(resources); err != nil {
	if strings.Contains(err.Error(), "namespace of resource cannot be null") {
		// set Metadata.Repository before retry
	}
	return err
}

When it happens

Trigger: Calling tencentcr PrepareForPush with ResourceMetadata that omits the Repository field (only Vtags/Artifact set).

Common situations: Tag-oriented metadata reused for push; struct clones dropping fields; builders where Repository assignment sits in a rarely-taken branch.
