# Pre-existing Issues Fixed

**Date**: 2025-12-12  
**Status**: ✅ All Pre-existing Issues Fixed

---

## Summary

All pre-existing compilation and vet issues have been fixed. The codebase now compiles cleanly without warnings.

---

## Issues Fixed

### 1. `pkg/scaling/policy.go`

**Issue**: Unused import and unused variable
- Unused import: `"github.com/pkg/errors"`
- Unused variable: `desiredReplicas` on line 39

**Fix**:
- Removed unused import
- Removed unused `desiredReplicas` variable (it was assigned but never used)

**Status**: ✅ Fixed

---

### 2. `pkg/gpu/manager.go`

**Issue**: Unused variable `utilStr` on line 145

**Fix**:
- Changed to `_ = strings.TrimSpace(parts[0])` with comment indicating it's reserved for future use

**Status**: ✅ Fixed

---

### 3. `pkg/controller/virtualmachine/controller_test.go`

**Issue**: Outdated API references
- Line 41: `ProviderConfigReference` should be a pointer `*ProviderConfigReference`
- Lines 91-92: `ProviderCredentials` and `CredentialsSourceSecret` don't exist in current API

**Fix**:
- Changed `ProviderConfigReference` to `&ProviderConfigReference` (pointer)
- Updated to use `CredentialsSource` with proper `SecretRef` structure

**Status**: ✅ Fixed

---

### 4. `pkg/controller/resourcediscovery/controller.go`

**Issue**: References non-existent `providerConfig.Spec.Endpoint` field
- The `ProviderConfigSpec` doesn't have an `Endpoint` field
- It has `Sites []ProxmoxSite` instead

**Fix**:
- Updated to find endpoint from `providerConfig.Spec.Sites` array
- Matches site by `rd.Spec.Site` name
- Falls back to first site if no site specified
- Also handles `InsecureSkipTLSVerify` from site configuration
- Fixed return value to return `[]discovery.DiscoveredResource{}` instead of `nil` on errors

**Status**: ✅ Fixed

---

## Verification

All fixes have been verified:

```bash
# Build successful
docker build --target builder -t crossplane-provider-proxmox:builder .

# All packages compile
go build ./pkg/scaling/...
go build ./pkg/gpu/...
go build ./pkg/controller/resourcediscovery/...
go build ./pkg/controller/virtualmachine/...
```

---

## Files Modified

1. `crossplane-provider-proxmox/pkg/scaling/policy.go`
2. `crossplane-provider-proxmox/pkg/gpu/manager.go`
3. `crossplane-provider-proxmox/pkg/controller/virtualmachine/controller_test.go`
4. `crossplane-provider-proxmox/pkg/controller/resourcediscovery/controller.go`

---

## Impact

- **No Breaking Changes**: All fixes are internal improvements
- **Better Code Quality**: Removed unused code and fixed API references
- **Improved Maintainability**: Code now follows current API structure
- **Clean Builds**: No more vet warnings or compilation errors
