fix(tests): improve context setup for audit logging in DNS provider service tests
- Updated context key definitions in dns_provider_service_test.go to use string constants instead of custom types for user_id, client_ip, and user_agent. - Ensured proper context values are set in audit logging tests to avoid defaulting to "system" or empty values. - Enhanced in-memory SQLite database setup in credential_service_test.go to use WAL mode and busy timeout for better concurrency during tests.

# CI Docker Build Failure Analysis & Fix Plan
|
||||
# Backend Coverage Investigation - PR #461
|
||||
|
||||
**Issue**: Docker Build workflow failing on PR builds during image artifact save
|
||||
**Workflow**: `.github/workflows/docker-build.yml`
|
||||
**Error**: `Error response from daemon: reference does not exist`
|
||||
**Date**: 2026-01-12
|
||||
**Status**: Analysis Complete - Ready for Implementation
|
||||
**Investigation Date**: 2026-01-12 06:30 UTC
|
||||
**Analyst**: GitHub Copilot
|
||||
**Status**: ✅ ROOT CAUSE IDENTIFIED
|
||||
**Issue**: Backend coverage below 85% threshold due to test failures
|
||||
|
||||
---
|
||||
|
||||
## Executive Summary
|
||||
|
||||
The `docker-build.yml` workflow is failing at the **"Save Docker Image as Artifact" step (lines 135-142)** for PR builds. The root cause is a **mismatch between the image name/tag format used by `docker/build-push-action` with `load: true` and the image reference manually constructed in the `docker save` command**.
|
||||
**CONFIRMED ROOT CAUSE**: Audit logging tests in `dns_provider_service_test.go` are failing because the request context (user_id, source_ip, user_agent) is not being properly set or extracted during test execution.
|
||||
|
||||
**Impact**: All PR builds fail at the artifact save step, preventing the `verify-supply-chain-pr` job from running.
|
||||
**Coverage Status**:
|
||||
- **Current**: 84.8%
|
||||
- **Required**: 85%
|
||||
- **Deficit**: 0.2%
|
||||
|
||||
**Fix Complexity**: **Low** - Single step modification to use the exact tag from metadata output instead of manually constructing it.
|
||||
**Test Status**:
|
||||
- ✅ **Passing**: 99% of tests (all tests except audit logging)
|
||||
- ❌ **Failing**: 6 audit logging tests in `internal/services/dns_provider_service_test.go`
|
||||
|
||||
**Impact**: Tests are failing → Coverage report generation is affected → Coverage drops below threshold
|
||||

## Root Cause Analysis
|
||||
## Detailed Findings
|
||||
|
||||
### 1. The Failing Step (Lines 135-142)
|
||||
### 1. Test Execution Results
|
||||
|
||||
**Location**: `.github/workflows/docker-build.yml`, lines 135-142
|
||||
**Command**: `/projects/Charon/scripts/go-test-coverage.sh`
|
||||
|
||||
```yaml
|
||||
- name: Save Docker Image as Artifact
|
||||
if: github.event_name == 'pull_request'
|
||||
run: |
|
||||
IMAGE_NAME=$(echo "${{ github.repository_owner }}/charon" | tr '[:upper:]' '[:lower:]')
|
||||
docker save ghcr.io/${IMAGE_NAME}:pr-${{ github.event.pull_request.number }} -o /tmp/charon-pr-image.tar
|
||||
ls -lh /tmp/charon-pr-image.tar
|
||||
**Duration**: ~32 seconds (normal, no hangs)
|
||||
|
||||
**Result Summary**:
|
||||
```
|
||||
PASS: 197 tests
|
||||
FAIL: 6 tests (all in dns_provider_service_test.go)
|
||||
Coverage: 84.8%
|
||||
Required: 85%
|
||||
Status: BELOW THRESHOLD
|
||||
```
|
||||
|
||||
**What Happens**:
|
||||
- **Line 140**: Normalizes repository owner name to lowercase (e.g., `Wikid82` → `wikid82`)
|
||||
- **Line 141**: **Constructs the image reference manually**: `ghcr.io/${IMAGE_NAME}:pr-${PR_NUMBER}`
|
||||
- **Line 141**: **Attempts to save the image** using this manually constructed reference
|
||||
### 2. Failing Tests Analysis
|
||||
|
||||
**The Problem**: The manually constructed image reference **assumes** the Docker image was loaded with the exact format `ghcr.io/wikid82/charon:pr-123`, but when `docker/build-push-action` uses `load: true`, the actual tag format applied to the local image may differ.
|
||||
**File**: `backend/internal/services/dns_provider_service_test.go`
|
||||
|
||||
### 2. The Build Step (Lines 111-123)
|
||||
**Failing Tests**:
|
||||
1. `TestDNSProviderService_AuditLogging_Create` (line 1589)
|
||||
2. `TestDNSProviderService_AuditLogging_Update` (line 1643)
|
||||
3. `TestDNSProviderService_AuditLogging_Delete` (line 1703)
|
||||
4. `TestDNSProviderService_AuditLogging_Test` (line 1747)
|
||||
5. `TestDNSProviderService_AuditLogging_GetDecryptedCredentials`
|
||||
6. `TestDNSProviderService_AuditLogging_ContextHelpers`
|
||||
|
||||
**Location**: `.github/workflows/docker-build.yml`, lines 111-123
|
||||
**Error Pattern**: All tests fail with the same assertion errors:
|
||||
|
||||
```yaml
|
||||
- name: Build and push Docker image
|
||||
if: steps.skip.outputs.skip_build != 'true'
|
||||
id: build-and-push
|
||||
uses: docker/build-push-action@263435318d21b8e681c14492fe198d362a7d2c83 # v6
|
||||
with:
|
||||
context: .
|
||||
platforms: ${{ github.event_name == 'pull_request' && 'linux/amd64' || 'linux/amd64,linux/arm64' }}
|
||||
push: ${{ github.event_name != 'pull_request' }}
|
||||
load: ${{ github.event_name == 'pull_request' }}
|
||||
tags: ${{ steps.meta.outputs.tags }}
|
||||
labels: ${{ steps.meta.outputs.labels }}
|
||||
no-cache: true
|
||||
pull: true
|
||||
build-args: |
|
||||
VERSION=${{ steps.meta.outputs.version }}
|
||||
BUILD_DATE=${{ fromJSON(steps.meta.outputs.json).labels['org.opencontainers.image.created'] }}
|
||||
VCS_REF=${{ github.sha }}
|
||||
CADDY_IMAGE=${{ steps.caddy.outputs.image }}
|
||||
```
|
||||
Expected: "test-user"
|
||||
Actual: "system"
|
||||
|
||||
Expected: "192.168.1.1"
|
||||
Actual: ""
|
||||
|
||||
Expected: "TestAgent/1.0"
|
||||
Actual: ""
|
||||
```
|
||||
|
||||
**Key Parameters for PR Builds**:
|
||||
- **Line 117**: `push: false` → Image is **not pushed** to the registry
|
||||
- **Line 118**: `load: true` → Image is **loaded into the local Docker daemon**
|
||||
- **Line 119**: `tags: ${{ steps.meta.outputs.tags }}` → Uses tags generated by the metadata action
|
||||
### 3. Root Cause Analysis
|
||||
|
||||
**Behavior with `load: true`**:
|
||||
- The image is built and loaded into the local Docker daemon
|
||||
- Tags from `steps.meta.outputs.tags` are applied to the image
|
||||
- For PR builds, this generates **one tag**: `ghcr.io/wikid82/charon:pr-123`
|
||||
**Problem**: The test context is not properly configured with audit metadata before service calls.
|
||||
|
||||
### 3. The Metadata Step (Lines 105-113)
|
||||
|
||||
**Location**: `.github/workflows/docker-build.yml`, lines 105-113
|
||||
|
||||
```yaml
|
||||
- name: Extract metadata (tags, labels)
|
||||
if: steps.skip.outputs.skip_build != 'true'
|
||||
id: meta
|
||||
uses: docker/metadata-action@c299e40c65443455700f0fdfc63efafe5b349051 # v5.10.0
|
||||
with:
|
||||
images: ${{ env.REGISTRY }}/${{ env.IMAGE_NAME }}
|
||||
tags: |
|
||||
type=raw,value=latest,enable={{is_default_branch}}
|
||||
type=raw,value=dev,enable=${{ github.ref == 'refs/heads/development' }}
|
||||
type=raw,value=beta,enable=${{ github.ref == 'refs/heads/feature/beta-release' }}
|
||||
type=raw,value=pr-${{ github.event.pull_request.number }},enable=${{ github.event_name == 'pull_request' }}
|
||||
type=sha,format=short,enable=${{ github.event_name != 'pull_request' }}
|
||||
**Evidence**:
|
||||
```go
|
||||
// Test expects these context values to be extracted:
|
||||
assert.Equal(t, "test-user", event.UserID) // ❌ Gets "system" instead
|
||||
assert.Equal(t, "192.168.1.1", event.SourceIP) // ❌ Gets "" instead
|
||||
assert.Equal(t, "TestAgent/1.0", event.UserAgent) // ❌ Gets "" instead
|
||||
```
|
||||
|
||||
**For PR builds**, only **line 111** is enabled:
|
||||
```yaml
|
||||
type=raw,value=pr-${{ github.event.pull_request.number }},enable=${{ github.event_name == 'pull_request' }}
|
||||
**Why This Happens**:
|
||||
1. Tests create a context: `ctx := context.Background()`
|
||||
2. Tests set context values (likely using wrong keys or format)
|
||||
3. Service calls `auditService.Log()` which extracts values from context
|
||||
4. Context extraction fails because keys don't match or values aren't set correctly
|
||||
5. Defaults to "system" for user_id and "" for IP/agent
|
||||
|
||||
**Location**: Lines 1589, 1593-1594, 1643, 1703, 1705, 1747+ in `dns_provider_service_test.go`
|
||||
|
||||
### 4. Coverage Impact
|
||||
|
||||
**Package-Level Coverage**:
|
||||
|
||||
| Package | Coverage | Status |
|
||||
|---------|----------|--------|
|
||||
| `internal/services` | **80.7%** | ❌ FAILED (6 failing tests) |
|
||||
| `internal/utils` | 74.2% | ✅ PASSING |
|
||||
| `pkg/dnsprovider/builtin` | 30.4% | ✅ PASSING |
|
||||
| `pkg/dnsprovider/custom` | 91.1% | ✅ PASSING |
|
||||
| `pkg/dnsprovider` | 0.0% | ⚠️ No tests (interface only) |
|
||||
| **Overall** | **84.8%** | ❌ BELOW 85% |
|
||||
|
||||
**Why Coverage Is Low**:
|
||||
- The failing tests in `internal/services` prevent the coverage report from being finalized correctly
|
||||
- Test failures cause the test suite to exit with non-zero status
|
||||
- This interrupts the coverage calculation process
|
||||
- The 0.2% shortfall is likely due to uncovered error paths in the audit logging code
|
||||
|
||||
### 5. Is This a Real Issue or CI Quirk?
|
||||
|
||||
**VERDICT**: ✅ **REAL ISSUE** (Not a CI quirk)
|
||||
|
||||
**Evidence**:
|
||||
1. ✅ Tests fail **locally** (reproduced on dev machine)
|
||||
2. ✅ Tests fail **consistently** (same 6 tests every time)
|
||||
3. ✅ Tests fail with **specific assertions** (not timeouts or random failures)
|
||||
4. ✅ The error messages are **deterministic** (always expect same values)
|
||||
5. ❌ No hangs, timeouts, or race conditions detected
|
||||
6. ❌ No CI-specific environment issues
|
||||
7. ❌ No timing-dependent failures
|
||||
|
||||
**Conclusion**: This is a legitimate test bug that must be fixed.

||||

|
||||
|
||||
## Specific Line Ranges Needing Tests
|
||||
|
||||
Based on the failure analysis, the following areas need attention:
|
||||
|
||||
### 1. Context Value Extraction in Tests
|
||||
|
||||
**File**: `backend/internal/services/dns_provider_service_test.go`
|
||||
|
||||
**Problem Lines**:
|
||||
- Lines 1580-1595 (Create test - context setup)
|
||||
- Lines 1635-1650 (Update test - context setup)
|
||||
- Lines 1695-1710 (Delete test - context setup)
|
||||
- Lines 1740-1755 (Test credentials test - context setup)
|
||||
|
||||
**What's Missing**: Proper context value injection using the correct context keys that the audit service expects.
|
||||
|
||||
**Expected Fix Pattern**:
|
||||
```go
|
||||
// WRONG (current):
|
||||
ctx := context.Background()
|
||||
|
||||
// RIGHT (needed):
|
||||
ctx := context.WithValue(context.Background(), middleware.UserIDKey, "test-user")
|
||||
ctx = context.WithValue(ctx, middleware.SourceIPKey, "192.168.1.1")
|
||||
ctx = context.WithValue(ctx, middleware.UserAgentKey, "TestAgent/1.0")
|
||||
```
|
||||
|
||||
**This generates a single tag**: `ghcr.io/wikid82/charon:pr-123`
|
||||
### 2. Audit Service Context Keys
|
||||
|
||||
**Note**: The `IMAGE_NAME` is already normalized to lowercase at lines 56-57:
|
||||
```yaml
|
||||
- name: Normalize image name
|
||||
run: |
|
||||
IMAGE_NAME=$(echo "${{ env.IMAGE_NAME }}" | tr '[:upper:]' '[:lower:]')
|
||||
echo "IMAGE_NAME=${IMAGE_NAME}" >> $GITHUB_ENV
|
||||
```
|
||||
**File**: `backend/internal/middleware/audit_context.go` (or similar)
|
||||
|
||||
So the metadata action receives `ghcr.io/wikid82/charon` (lowercase) as input.
|
||||
**Problem**: The tests don't know which context keys to use, or the keys are not exported.
|
||||
|
||||
### 4. The Critical Issue: Tag Mismatch
|
||||
**What's Needed**:
|
||||
- Document or export the correct context key constants
|
||||
- Ensure test files import the correct package
|
||||
- Ensure context keys match between middleware and service
|
||||
|
||||
When `docker/build-push-action` uses `load: true`, the behavior is:
|
||||
### 3. Coverage Gaps (Non-Failure Related)
|
||||
|
||||
1. ✅ **Expected**: Image is loaded with tags from `steps.meta.outputs.tags` → `ghcr.io/wikid82/charon:pr-123`
|
||||
2. ❌ **Reality**: The exact tag format depends on Docker Buildx's internal behavior
|
||||
**File**: `backend/internal/utils/*.go`
|
||||
|
||||
The `docker save` command at line 141 tries to save:
|
||||
**Coverage**: 74.2% (needs 85%)
|
||||
|
||||
**Missing Coverage**:
|
||||
- Error handling paths in URL validation
|
||||
- Edge cases in network utility functions
|
||||
- Rarely-used helper functions
|
||||
|
||||
**Recommendation**: Add targeted tests after fixing audit logging tests.
|
||||
|
||||
---
|
||||
|
||||
## Recommended Fix
|
||||
|
||||
### Step 1: Identify Correct Context Keys
|
||||
|
||||
**Action**: Find the context key definitions used by the audit service.
|
||||
|
||||
**Likely Location**:
|
||||
```bash
|
||||
ghcr.io/${IMAGE_NAME}:pr-${{ github.event.pull_request.number }}
|
||||
grep -r "UserIDKey\|SourceIPKey\|UserAgentKey" backend/internal/
|
||||
```
|
||||
|
||||
But this **manually reconstructs** the tag instead of using the **actual tag applied by docker/build-push-action**.
|
||||
**Expected Files**:
|
||||
- `backend/internal/middleware/auth.go`
|
||||
- `backend/internal/middleware/audit.go`
|
||||
- `backend/internal/middleware/context.go`
|
||||
|
||||
**Why This Fails**:
|
||||
- The `docker save` command requires an **exact match** of the image reference as it exists in the local Docker daemon
|
||||
- If the image is loaded with a slightly different tag format, `docker save` throws:
|
||||
```
|
||||
Error response from daemon: reference does not exist
|
||||
```
|
||||
### Step 2: Update Test Context Setup
|
||||
|
||||
**Evidence from Error Log**:
|
||||
```
|
||||
Run IMAGE_NAME=$(echo "Wikid82/charon" | tr '[:upper:]' '[:lower:]')
|
||||
Error response from daemon: reference does not exist
|
||||
Error: Process completed with exit code 1.
|
||||
**File**: `backend/internal/services/dns_provider_service_test.go`
|
||||
|
||||
**Lines to Fix**: 1580-1595, 1635-1650, 1695-1710, 1740-1755
|
||||
|
||||
**Pattern**:
|
||||
```go
|
||||
// Import the middleware package
|
||||
import "github.com/Wikid82/charon/backend/internal/middleware"
|
||||
|
||||
// In each test, replace context setup with:
|
||||
ctx := context.WithValue(context.Background(), middleware.UserIDKey, "test-user")
|
||||
ctx = context.WithValue(ctx, middleware.SourceIPKey, "192.168.1.1")
|
||||
ctx = context.WithValue(ctx, middleware.UserAgentKey, "TestAgent/1.0")
|
||||
```
|
||||
|
||||
This confirms the `docker save` command cannot find the image reference constructed at line 141.
|
||||
### Step 3: Re-run Tests
|
||||
|
||||
### 5. Job Dependencies Analysis
|
||||
|
||||
**Complete Workflow Structure**:
|
||||
|
||||
```
|
||||
build-and-push (lines 34-234)
|
||||
├── Outputs: skip_build, digest
|
||||
├── Steps:
|
||||

├── needs: build-and-push
|

|
||||
├── Steps:
|
||||
│ ├── ❌ Download artifact (artifact doesn't exist)
|
||||
│ ├── ❌ Load image (cannot load non-existent artifact)
|
||||
│ └── ❌ Scan image (cannot scan non-loaded image)

verify-supply-chain-pr-skipped (lines 724-754)
|

├── needs: build-and-push
|
||||
└── if: github.event_name == 'pull_request' && needs.build-and-push.outputs.skip_build == 'true'
|
||||
```
|
||||
|
||||
**Dependency Chain Impact**:
|
||||
|
||||
1. ❌ `build-and-push` **fails** at line 141 (`docker save`)
|
||||
2. ❌ Artifact is **never uploaded** (lines 144-150 are skipped)
|
||||
3. ❌ `verify-supply-chain-pr` **cannot download** artifact (line 517 fails)
|
||||
4. ❌ **Supply chain verification never runs** for PRs
|
||||
|
||||
### 6. Verification: Why Similar Patterns Work
|
||||
|
||||
**Line 376** (in `test-image` job):
|
||||
```yaml
|
||||
- name: Normalize image name
|
||||
run: |
|
||||
raw="${{ github.repository_owner }}/${{ github.event.repository.name }}"
|
||||
IMAGE_NAME=$(echo "$raw" | tr '[:upper:]' '[:lower:]')
|
||||
echo "IMAGE_NAME=${IMAGE_NAME}" >> $GITHUB_ENV
|
||||
```
|
||||
|
||||
This job **pulls from the registry** (line 395):
|
||||
```yaml
|
||||
- name: Pull Docker image
|
||||
run: docker pull ${{ env.REGISTRY }}/${{ env.IMAGE_NAME }}:${{ steps.tag.outputs.tag }}
|
||||
```
|
||||
|
||||
✅ **Works because**: It pulls a pushed image from the registry, not a locally loaded one.
|
||||
|
||||
**Line 516** (in `verify-supply-chain-pr` job):
|
||||
```yaml
|
||||
- name: Normalize image name
|
||||
run: |
|
||||
IMAGE_NAME=$(echo "${{ github.repository_owner }}/charon" | tr '[:upper:]' '[:lower:]')
|
||||
echo "IMAGE_NAME=${IMAGE_NAME}" >> $GITHUB_ENV
|
||||
```
|
||||
|
||||
✅ **Would work if**: The artifact existed. This job loads the image from the tar file, which preserves the exact tags.
|
||||
|
||||
**Key Difference**: The failing step tries to save an image **before we know its exact tag**, while the working patterns either:
|
||||
- Pull from registry with a known tag
|
||||
- Load from artifact with preserved tags
|
||||
|
||||
---
|
||||
|
||||
## The Solution
|
||||
|
||||
### Option 1: Use Metadata Output Tag (RECOMMENDED ✅)
|
||||
|
||||
**Strategy**: Extract the exact tag from `steps.meta.outputs.tags` and use it directly in `docker save`.
|
||||
|
||||
**Why This Works**:
|
||||
- The `docker/metadata-action` generates the tags that `docker/build-push-action` **actually applies** to the image
|
||||
- For PR builds, this is: `ghcr.io/<owner>/charon:pr-<number>` (normalized, lowercase)
|
||||
- This is the **exact tag** that exists in the local Docker daemon after `load: true`
|
||||
|
||||
**Rationale**:
|
||||
- Avoids manual tag reconstruction
|
||||
- Uses the authoritative source of truth for image tags
|
||||
- Eliminates assumption-based errors
|
||||
|
||||
**Risk Level**: **Low** - Read-only operation on existing step outputs
|
||||
|
||||
### Option 2: Inspect Local Images (ALTERNATIVE)
|
||||
|
||||
**Strategy**: Use `docker images` to discover the actual tag before saving.
|
||||
|
||||
**Why Not Recommended**:
|
||||
- Adds complexity
|
||||
- Requires pattern matching or parsing
|
||||
- Less reliable than using metadata output
|
||||
|
||||
### Option 3: Override Tag for PRs (FALLBACK)
|
||||
|
||||
**Strategy**: Modify the build step to apply a deterministic local tag for PR builds.
|
||||
|
||||
**Why Not Recommended**:
|
||||
- Requires more changes (build step + save step)
|
||||
- Breaks consistency with existing tag patterns
|
||||
- Downstream jobs expect registry-style tags
|
||||

|
||||
## Recommended Fix: Option 1
|
||||
|
||||
### Implementation
|
||||
|
||||
**File**: `.github/workflows/docker-build.yml`
|
||||
**Location**: Lines 135-142 (Save Docker Image as Artifact step)
|
||||
|
||||
#### Before (Current - BROKEN)
|
||||
|
||||
```yaml
|
||||
- name: Save Docker Image as Artifact
|
||||
if: github.event_name == 'pull_request'
|
||||
run: |
|
||||
IMAGE_NAME=$(echo "${{ github.repository_owner }}/charon" | tr '[:upper:]' '[:lower:]')
|
||||
docker save ghcr.io/${IMAGE_NAME}:pr-${{ github.event.pull_request.number }} -o /tmp/charon-pr-image.tar
|
||||
ls -lh /tmp/charon-pr-image.tar
|
||||
```
|
||||
|
||||
**Issue**: Manually constructs the image reference, which may not match the actual tag applied by `docker/build-push-action`.
|
||||
|
||||
#### After (FIXED - Concise Version)
|
||||
|
||||
```yaml
|
||||
- name: Save Docker Image as Artifact
|
||||
if: github.event_name == 'pull_request'
|
||||
run: |
|
||||
# Extract the first tag from metadata action (PR tag)
|
||||
IMAGE_TAG=$(echo "${{ steps.meta.outputs.tags }}" | head -n 1)
|
||||
echo "🔍 Detected image tag: ${IMAGE_TAG}"
|
||||
|
||||
# Verify the image exists locally
|
||||
echo "📋 Available local images:"
|
||||
docker images --filter "reference=*charon*"
|
||||
|
||||
# Save the image using the exact tag from metadata
|
||||
echo "💾 Saving image: ${IMAGE_TAG}"
|
||||
docker save "${IMAGE_TAG}" -o /tmp/charon-pr-image.tar
|
||||
|
||||
# Verify the artifact was created
|
||||
echo "✅ Artifact created:"
|
||||
ls -lh /tmp/charon-pr-image.tar
|
||||
```
|
||||
|
||||
#### After (FIXED - Defensive Version for Production)
|
||||
|
||||
```yaml
|
||||
- name: Save Docker Image as Artifact
|
||||
if: github.event_name == 'pull_request'
|
||||
run: |
|
||||
# Extract the first tag from metadata action (PR tag)
|
||||
IMAGE_TAG=$(echo "${{ steps.meta.outputs.tags }}" | head -n 1)
|
||||
|
||||
if [[ -z "${IMAGE_TAG}" ]]; then
|
||||
echo "❌ ERROR: No image tag found in metadata output"
|
||||
echo "Metadata tags output:"
|
||||
echo "${{ steps.meta.outputs.tags }}"
|
||||
exit 1
|
||||
fi
|
||||
|
||||
echo "🔍 Detected image tag: ${IMAGE_TAG}"
|
||||
|
||||
# Verify the image exists locally
|
||||
if ! docker image inspect "${IMAGE_TAG}" >/dev/null 2>&1; then
|
||||
echo "❌ ERROR: Image ${IMAGE_TAG} not found locally"
|
||||
echo "📋 Available images:"
|
||||
docker images
|
||||
exit 1
|
||||
fi
|
||||
|
||||
# Save the image using the exact tag from metadata
|
||||
echo "💾 Saving image: ${IMAGE_TAG}"
|
||||
docker save "${IMAGE_TAG}" -o /tmp/charon-pr-image.tar
|
||||
|
||||
# Verify the artifact was created
|
||||
echo "✅ Artifact created:"
|
||||
ls -lh /tmp/charon-pr-image.tar
|
||||
```
|
||||
|
||||
**Key Changes**:
|
||||
|
||||
1. **Extract exact tag**: `IMAGE_TAG=$(echo "${{ steps.meta.outputs.tags }}" | head -n 1)`
|
||||
- Uses the first (and only) tag from metadata output
|
||||
- For PR builds: `ghcr.io/wikid82/charon:pr-123`
|
||||
|
||||
2. **Add debugging**: `docker images --filter "reference=*charon*"`
|
||||
- Shows available images for troubleshooting
|
||||
- Helps diagnose tag mismatches in logs
|
||||
|
||||
3. **Use extracted tag**: `docker save "${IMAGE_TAG}" -o /tmp/charon-pr-image.tar`
|
||||
- No manual reconstruction
|
||||
- Guaranteed to match the actual image tag
|
||||
|
||||
4. **Defensive checks** (production version only):
|
||||
- Verify `IMAGE_TAG` is not empty
|
||||
- Verify image exists before attempting save
|
||||
- Fail fast with clear error messages
|
||||
|
||||
**Why This Works**:
|
||||
|
||||
- ✅ The `docker/metadata-action` output is the **authoritative source** of tags
|
||||
- ✅ These are the **exact tags** applied by `docker/build-push-action`
|
||||
- ✅ No assumptions or manual reconstruction
|
||||
- ✅ Works for any repository owner name (uppercase, lowercase, mixed case)
|
||||
- ✅ Consistent with downstream jobs that expect the same tag format
|
||||
|
||||
**Null Safety**:
|
||||
|
||||
- If `steps.meta.outputs.tags` is empty (shouldn't happen), `IMAGE_TAG` will be empty
|
||||
- The defensive version explicitly checks for this and fails with a clear message
|
||||
- The concise version will fail at `docker save` with a clear error about missing image reference
|
||||

|
||||
|
||||
## Side Effects & Related Updates
|
||||
|
||||
### No Changes Needed ✅
|
||||
|
||||
The following steps/jobs **already handle the image correctly** and require **no modifications**:
|
||||
|
||||
1. **Upload Image Artifact** (lines 144-150)
|
||||
- ✅ Uses the saved tar file from the previous step
|
||||
- ✅ No dependency on image tag format
|
||||
|
||||
2. **verify-supply-chain-pr job** (lines 495-722)
|
||||
- ✅ Downloads and loads the tar file
|
||||
- ✅ References image using the same normalization logic
|
||||
- ✅ Will work correctly once artifact exists
|
||||
|
||||
3. **Load Docker Image step** (lines 524-529)
|
||||
- ✅ Loads from tar file (preserves original tags)
|
||||
- ✅ No changes needed
|
||||
|
||||
### Why No Downstream Changes Are Needed
|
||||
|
||||
When you save a Docker image to a tar file using `docker save`, the tar file contains:
|
||||
- The image layers
|
||||
- The image configuration
|
||||
- **The exact tags that were applied to the image**
|
||||
|
||||
When you load the image using `docker load -i charon-pr-image.tar`, Docker restores:
|
||||
- All image layers
|
||||
- The image configuration
|
||||
- **The exact same tags** that were saved
|
||||
|
||||
**Example**:
|
||||
**Command**:
|
||||
```bash
|
||||
# Save with tag: ghcr.io/wikid82/charon:pr-123
|
||||
docker save ghcr.io/wikid82/charon:pr-123 -o image.tar
|
||||
|
||||
# Load restores the exact same tag
|
||||
docker load -i image.tar
|
||||
|
||||
# Image is now available as: ghcr.io/wikid82/charon:pr-123
|
||||
docker images ghcr.io/wikid82/charon:pr-123
|
||||
cd /projects/Charon/backend
|
||||
go test -v -race ./internal/services/... -run TestDNSProviderService_AuditLogging
|
||||
```
|
||||
|
||||
The `verify-supply-chain-pr` job references:
|
||||
**Expected**: All 6 tests pass
|
||||
|
||||
### Step 4: Verify Coverage
|
||||
|
||||
**Command**:
|
||||
```bash
|
||||
IMAGE_REF="ghcr.io/${{ env.IMAGE_NAME }}:pr-${{ github.event.pull_request.number }}"
|
||||
/projects/Charon/scripts/go-test-coverage.sh
|
||||
```
|
||||
|
||||
This will match perfectly because:
|
||||
- `IMAGE_NAME` is normalized the same way (lines 516-518)
|
||||
- The PR number is the same
|
||||
- The loaded image has the exact tag we saved
|
||||
**Expected**: Coverage ≥85%
|
||||

|
||||
|
||||
## Confidence Assessment
|
||||
|
||||
**Overall Confidence**: 🟢 **95%**
|
||||
|
||||
**High Confidence (>90%)**:
|
||||
- ✅ Root cause is identified (context values not set correctly)
|
||||
- ✅ Failure pattern is consistent (same 6 tests, same assertions)
|
||||
- ✅ Fix is straightforward (update context setup in tests)
|
||||
- ✅ No concurrency issues, hangs, or timeouts
|
||||
- ✅ All other tests pass successfully
|
||||
|
||||
**Low Risk Areas**:
|
||||
- Tests run quickly (no hangs)
|
||||
- No race conditions detected
|
||||
- No CI-specific issues

|
||||
|
||||
## Is This Blocking the PR?
|
||||
|
||||
**YES** - This is blocking PR #461 from merging.
|
||||
|
||||
**Why**:
|
||||
1. ✅ Coverage is below 85% threshold (84.8%)
|
||||
2. ✅ Codecov workflow will fail (requires ≥85%)
|
||||
3. ✅ Quality checks workflow will fail (test failures)
|
||||
4. ✅ PR cannot be merged with failing required checks
|
||||
|
||||
**Severity**: 🔴 **CRITICAL** (blocks merge)
|
||||
|
||||
**Priority**: 🔴 **P0** (must fix before merge)

## IMMEDIATE ACTIONS (Next 30 Minutes) ⚡
|
||||
|
||||
### 1. Find Context Key Definitions
|
||||
|
||||
**Execute this command**:
|
||||
```bash
|
||||
cd /projects/Charon/backend
|
||||
grep -rn "type contextKey\|UserIDKey\|SourceIPKey\|UserAgentKey" internal/middleware internal/security internal/auth 2>/dev/null | head -20
|
||||
```
|
||||
|
||||
**Expected Output**: File and line numbers where context keys are defined
|
||||
|
||||
**Timeline**: 2 minutes
|
||||
|
||||
---
|
||||
|
||||
### 2. Inspect Audit Logging Test Setup
|
||||
|
||||
**Execute this command**:
|
||||
```bash
|
||||
cd /projects/Charon/backend
|
||||
sed -n '1580,1600p' internal/services/dns_provider_service_test.go
|
||||
```
|
||||
|
||||
**Look For**:
|
||||
- How context is created
|
||||
- What context values are set
|
||||
- What imports are used
|
||||
|
||||
**Timeline**: 3 minutes
|
||||
|
||||
---
|
||||
|
||||
### 3. Compare with Working Audit Tests
|
||||
|
||||
**Execute this command**:
|
||||
```bash
|
||||
cd /projects/Charon/backend
|
||||
grep -rn "AuditLogging.*context.WithValue" internal/ --include="*_test.go" | head -10
|
||||
```
|
||||
|
||||
**Purpose**: Find examples of correctly setting audit context in other tests
|
||||
|
||||
**Timeline**: 2 minutes
|
||||
|
||||
---
|
||||
|
||||
## FIX IMPLEMENTATION (Next 20 Minutes) 🔧
|
||||
|
||||
Once context keys are identified:
|
||||
|
||||
1. **Update test helper or inline context setup** in `dns_provider_service_test.go`
|
||||
2. **Apply to all 6 failing tests** (lines 1580-1595, 1635-1650, 1695-1710, 1740-1755, etc.)
|
||||
3. **Re-run tests** to validate fix
|
||||
4. **Verify coverage** reaches ≥85%
|
||||
|
||||
**Timeline**: 20 minutes
|
||||
|
||||
---
|
||||
|
||||
## VALIDATION (Next 5 Minutes) ✅
|
||||
|
||||
```bash
|
||||
# 1. Build a PR-style image locally
|
||||
docker build -t ghcr.io/wikid82/charon:pr-test .
|
||||
# Step 1: Run failing tests
|
||||
cd /projects/Charon/backend
|
||||
go test -v ./internal/services/... -run TestDNSProviderService_AuditLogging
|
||||
|
||||
# 2. Verify the image exists
|
||||
docker images ghcr.io/wikid82/charon:pr-test
|
||||
# Step 2: Run full coverage
|
||||
/projects/Charon/scripts/go-test-coverage.sh
|
||||
|
||||
# 3. Save the image
|
||||
docker save ghcr.io/wikid82/charon:pr-test -o /tmp/test-image.tar
|
||||
|
||||
# 4. Verify the tar was created
|
||||
ls -lh /tmp/test-image.tar
|
||||
|
||||
# 5. Load the image in a clean environment
|
||||
docker rmi ghcr.io/wikid82/charon:pr-test # Remove original
|
||||
docker load -i /tmp/test-image.tar # Reload from tar
|
||||
docker images ghcr.io/wikid82/charon:pr-test # Verify it's back
|
||||
# Step 3: Check coverage percentage
|
||||
tail -5 backend/test-output.txt
|
||||
```
|
||||
|
||||
**Expected Result**: All steps succeed without "reference does not exist" errors.
|
||||
|
||||
### Phase 2: CI Testing
|
||||
|
||||
1. **Apply the fix** to `.github/workflows/docker-build.yml` (lines 135-142)
|
||||
2. **Create a test PR** on the `feature/beta-release` branch
|
||||
3. **Verify the workflow execution**:
|
||||
- ✅ `build-and-push` job completes successfully
|
||||
- ✅ "Save Docker Image as Artifact" step shows detected tag in logs
|
||||
- ✅ "Upload Image Artifact" step uploads the tar file
|
||||
- ✅ `verify-supply-chain-pr` job runs and downloads the artifact
|
||||
- ✅ "Load Docker Image" step loads the image successfully
|
||||
- ✅ SBOM generation and vulnerability scanning complete
|
||||
|
||||
### Phase 3: Edge Cases
|
||||
|
||||
Test the following scenarios:
|
||||
|
||||
1. **Different repository owners** (uppercase, lowercase, mixed case):
|
||||
- `Wikid82/charon` → `wikid82/charon`
|
||||
- `TestUser/charon` → `testuser/charon`
|
||||
- `UPPERCASE/charon` → `uppercase/charon`
|
||||
|
||||
2. **Multiple rapid commits** to the same PR:
|
||||
- Verify no artifact conflicts
|
||||
- Verify each commit gets its own workflow run
|
||||
|
||||
3. **Skipped builds** (chore commits):
|
||||
- Verify `verify-supply-chain-pr-skipped` runs correctly
|
||||
- Verify feedback comment is posted
|
||||
|
||||
4. **Different PR numbers**:
|
||||
- Single digit (PR #5)
|
||||
- Double digit (PR #42)
|
||||
- Triple digit (PR #123)
|
||||
|
||||
### Phase 4: Rollback Plan
|
||||
|
||||
If the fix causes issues:
|
||||
|
||||
1. **Immediate rollback**: Revert the commit that applied this fix
|
||||
2. **Temporary workaround**: Disable artifact save/upload steps:
|
||||
```yaml
|
||||
if: github.event_name == 'pull_request' && false # Temporarily disabled
|
||||
```
|
||||
3. **Investigation**: Check GitHub Actions logs for actual image tags:
|
||||
```yaml
|
||||
# Add this step before the save step
|
||||
- name: Debug Image Tags
|
||||
if: github.event_name == 'pull_request'
|
||||
run: |
|
||||
echo "Metadata tags:"
|
||||
echo "${{ steps.meta.outputs.tags }}"
|
||||
echo ""
|
||||
echo "Local images:"
|
||||
docker images
|
||||
```
|
||||
**Expected**:
|
||||
- ✅ All 6 tests pass
|
||||
- ✅ Coverage ≥85%
|
||||
- ✅ No test failures
|
||||

|
||||
## Success Criteria
|
||||
## SUMMARY OF FINDINGS
|
||||
|
||||
### Functional
|
||||
### Root Cause
|
||||
**Context values for audit logging are not properly set in DNS provider service tests**, causing:
|
||||
- user_id to default to "system" instead of test value
|
||||
- source_ip to be empty instead of test IP
|
||||
- user_agent to be empty instead of test agent string
|
||||
|
||||
- ✅ `build-and-push` job completes successfully for all PR builds
|
||||
- ✅ Docker image artifact is saved and uploaded for all PR builds
|
||||
- ✅ `verify-supply-chain-pr` job runs and downloads the artifact
|
||||
- ✅ No "reference does not exist" errors in any step
|
||||
- ✅ Supply chain verification completes for all PR builds
|
||||
### Impact
|
||||
- ❌ 6 tests failing in `internal/services/dns_provider_service_test.go`

| Permissions Issue | ❌ Unlikely | Other Docker commands work |
|
||||
|
||||
**Conclusion**: **Tag Mismatch** is the root cause.
|
||||
|
||||
### Evidence Supporting Root Cause
|
||||
|
||||
1. ✅ **Build step succeeds** (no reported build failures)
|
||||
2. ✅ **Error occurs at `docker save`** (after successful build)
|
||||
3. ✅ **Manual tag reconstruction** (lines 140-141)
|
||||
4. ✅ **Inconsistent with docker/build-push-action behavior** when `load: true`
|
||||
5. ✅ **Similar patterns work** because they either:
|
||||
- Pull from registry (test-image job)
|
||||
- Load from artifact (verify-supply-chain-pr job)
|
||||
|
||||
### Fix Summary
|
||||
|
||||
**What Changed**: Use exact tag from `steps.meta.outputs.tags` instead of manually constructing it
|
||||
|
||||
**Why It Works**: The metadata action output is the authoritative source of tags applied by docker/build-push-action
|
||||
|
||||
**Risk Level**: **Low** - Read-only operation on existing step outputs
