Phase 6: ContentPermissionManager Implementation Plan

For Claude: REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.


Version History

Version Date Changes
1.0 2025-12-23 Initial plan
1.1 2025-12-23 Applied critical review feedback: file location changed to Infrastructure, added input validation, fixed ArgumentNullException pattern, added logging
1.2 2025-12-23 Applied critical review 2 feedback: REVERTED file location to Core (Infrastructure placement was blocking architectural violation), added permission character validation warning
1.3 2025-12-23 Applied critical review 3 feedback: FIXED DI registration file path (now Core/UmbracoBuilder.cs not Infrastructure), confirmed directory path has no /Content/ subdirectory, documented constructor parameter position and AddScoped choice

Goal: Extract permission operations (SetPermissions, SetPermission, GetPermissions) from ContentService into an internal ContentPermissionManager class.

Architecture: The ContentPermissionManager will be an internal class that encapsulates all permission-related operations. It will be registered as a scoped service in DI and injected into ContentService for delegation. Unlike the public operation services (IContentCrudService, etc.), this is an internal helper class per the design document specification.

Tech Stack: .NET 10.0, Umbraco.Core, NUnit for testing


Pre-Implementation Checklist

Before starting, verify the baseline:

# Run permission tests to establish baseline
dotnet test tests/Umbraco.Tests.Integration --filter "FullyQualifiedName~ContentServiceRefactoringTests" --no-build

# Run all ContentService tests
dotnet test tests/Umbraco.Tests.Integration --filter "FullyQualifiedName~ContentService" --no-build

Expected: All tests pass (including the 4 permission tests: 9, 10, 11, 12).


Task 1: Create ContentPermissionManager Class

Files:

  • Create: src/Umbraco.Core/Services/ContentPermissionManager.cs

v1.2 Change: File location REVERTED to Umbraco.Core. The v1.1 change to Infrastructure was a blocking architectural violation - Core cannot reference Infrastructure (wrong dependency direction). All Phases 1-5 extracted services are in Core, following the established pattern.

Step 1: Verify target directory exists

The file will be placed directly in src/Umbraco.Core/Services/ to match the pattern from Phases 1-5:

ls src/Umbraco.Core/Services/ContentCrudService.cs  # Should exist from Phase 1

Step 2: Create the ContentPermissionManager class

// src/Umbraco.Core/Services/ContentPermissionManager.cs
using Microsoft.Extensions.Logging;
using Umbraco.Cms.Core.Models;
using Umbraco.Cms.Core.Models.Entities;
using Umbraco.Cms.Core.Models.Membership;
using Umbraco.Cms.Core.Persistence.Repositories;
using Umbraco.Cms.Core.Scoping;

    }
}

Step 3: Verify the file compiles

dotnet build src/Umbraco.Core/Umbraco.Core.csproj --no-restore

Expected: Build succeeds.

Step 4: Commit

git add src/Umbraco.Core/Services/ContentPermissionManager.cs
git commit -m "feat(core): add ContentPermissionManager for Phase 6 extraction

🤖 Generated with [Claude Code](https://claude.com/claude-code)

Task 2: Register ContentPermissionManager in DI

Files:

  • Modify: src/Umbraco.Core/DependencyInjection/UmbracoBuilder.cs

v1.3 Change: DI registration is in Umbraco.Core/DependencyInjection/UmbracoBuilder.cs (not Infrastructure), matching Phases 1-5 pattern. The ContentService factory and all extracted services are registered here (lines ~301-329).

Step 1: Register the ContentPermissionManager

Find the service registrations section in UmbracoBuilder.cs (around line 305, after AddUnique<IContentPublishOperationService>) and add:

// Phase 6: Internal permission manager (AddScoped, not AddUnique, because it's internal without interface)
Services.AddScoped<ContentPermissionManager>();

Design Note (v1.3): We use AddScoped instead of AddUnique because:

  • AddUnique is for interface-based registrations (prevents duplicate implementations)
  • ContentPermissionManager is internal without an interface (per design document)
  • Scoped lifetime matches ContentService's request-scoped usage patterns

Add this line after the ContentPublishOperationService registration (around line 305) and before the IContentService factory registration.

Step 2: Verify the registration compiles

dotnet build src/Umbraco.Core/Umbraco.Core.csproj --no-restore

Expected: Build succeeds.

Step 3: Commit

git add src/Umbraco.Core/DependencyInjection/UmbracoBuilder.cs
git commit -m "chore(di): register ContentPermissionManager as scoped service

Phase 6: Internal permission manager with scoped lifetime.

Task 3: Add ContentPermissionManager to ContentService Constructor

Files:

  • Modify: src/Umbraco.Core/Services/ContentService.cs

Step 1: Verify the using directive

The Umbraco.Cms.Core.Services namespace should already be available (same namespace). No additional using directive needed.

v1.2 Change: No using directive needed - ContentPermissionManager is in the same namespace as ContentService (Umbraco.Cms.Core.Services).

Step 2: Add private field for ContentPermissionManager

In the field declarations section (around line 48), add:

// Permission manager field (for Phase 6 extracted permission operations)
private readonly ContentPermissionManager? _permissionManager;
private readonly Lazy<ContentPermissionManager>? _permissionManagerLazy;

Step 3: Add property accessor

After the PublishOperationService property (around line 100), add:

/// <summary>
/// Gets the permission manager.
/// </summary>
/// <exception cref="InvalidOperationException">Thrown if the manager was not properly initialized.</exception>
private ContentPermissionManager PermissionManager =>
    _permissionManager ?? _permissionManagerLazy?.Value
    ?? throw new InvalidOperationException("PermissionManager not initialized. Ensure the manager is properly injected via constructor.");

Step 4: Update the primary constructor (ActivatorUtilitiesConstructor)

Add the new parameter to the primary constructor (the one with [ActivatorUtilitiesConstructor]).

v1.3 Note: The ContentService constructor currently has 21 parameters (lines 105-127). ContentPermissionManager will be parameter 22, added AFTER publishOperationService. The exact order matters for the DI factory in Task 4.

[Microsoft.Extensions.DependencyInjection.ActivatorUtilitiesConstructor]
public ContentService(
    ICoreScopeProvider provider,                        // 1
    ILoggerFactory loggerFactory,                       // 2
    IEventMessagesFactory eventMessagesFactory,         // 3
    IDocumentRepository documentRepository,             // 4
    IEntityRepository entityRepository,                 // 5
    IAuditService auditService,                         // 6
    IContentTypeRepository contentTypeRepository,       // 7
    IDocumentBlueprintRepository documentBlueprintRepository, // 8
    ILanguageRepository languageRepository,             // 9
    Lazy<IPropertyValidationService> propertyValidationService, // 10
    IShortStringHelper shortStringHelper,               // 11
    ICultureImpactFactory cultureImpactFactory,         // 12
    IUserIdKeyResolver userIdKeyResolver,               // 13
    PropertyEditorCollection propertyEditorCollection,  // 14
    IIdKeyMap idKeyMap,                                 // 15
    IOptionsMonitor<ContentSettings> optionsMonitor,    // 16
    IRelationService relationService,                   // 17
    IContentCrudService crudService,                    // 18
    IContentQueryOperationService queryOperationService, // 19
    IContentVersionOperationService versionOperationService, // 20
    IContentMoveOperationService moveOperationService,  // 21
    IContentPublishOperationService publishOperationService, // 22
    ContentPermissionManager permissionManager)         // 23 - NEW Phase 6 permission operations

And in the constructor body, add:

// Phase 6: Permission manager (direct injection)
ArgumentNullException.ThrowIfNull(permissionManager);
_permissionManager = permissionManager;
_permissionManagerLazy = null;  // Not needed when directly injected

Step 5: Update the obsolete constructors

For each obsolete constructor, add lazy resolution:

// Phase 6: Lazy resolution of ContentPermissionManager
_permissionManagerLazy = new Lazy<ContentPermissionManager>(() =>
    StaticServiceProvider.Instance.GetRequiredService<ContentPermissionManager>(),
    LazyThreadSafetyMode.ExecutionAndPublication);

Step 6: Verify the file compiles

dotnet build src/Umbraco.Core/Umbraco.Core.csproj --no-restore

Expected: Build succeeds.

Step 7: Commit

git add src/Umbraco.Core/Services/ContentService.cs
git commit -m "refactor(core): inject ContentPermissionManager into ContentService

Phase 6: Add constructor parameter and lazy fallback for ContentPermissionManager.

Task 4: Update DI Registration to Pass ContentPermissionManager

Files:

  • Modify: src/Umbraco.Core/DependencyInjection/UmbracoBuilder.cs

v1.3 Change: Factory is in Umbraco.Core/DependencyInjection/UmbracoBuilder.cs (lines ~306-329), not Infrastructure. This matches where we registered ContentPermissionManager in Task 2.

Step 1: Update the ContentService factory registration

Find the ContentService factory registration in UmbracoBuilder.cs (around lines 306-329) and add the new parameter as the 23rd parameter (matching the constructor order from Task 3):

Services.AddUnique<IContentService>(sp =>
    new ContentService(
        sp.GetRequiredService<ICoreScopeProvider>(),           // 1
        sp.GetRequiredService<ILoggerFactory>(),               // 2
        sp.GetRequiredService<IEventMessagesFactory>(),        // 3
        sp.GetRequiredService<IDocumentRepository>(),          // 4
        sp.GetRequiredService<IEntityRepository>(),            // 5
        sp.GetRequiredService<IAuditService>(),                // 6
        sp.GetRequiredService<IContentTypeRepository>(),       // 7
        sp.GetRequiredService<IDocumentBlueprintRepository>(), // 8
        sp.GetRequiredService<ILanguageRepository>(),          // 9
        new Lazy<IPropertyValidationService>(() => sp.GetRequiredService<IPropertyValidationService>()), // 10
        sp.GetRequiredService<IShortStringHelper>(),           // 11
        sp.GetRequiredService<ICultureImpactFactory>(),        // 12

        sp.GetRequiredService<IRelationService>(),             // 17
        sp.GetRequiredService<IContentCrudService>(),          // 18
        sp.GetRequiredService<IContentQueryOperationService>(), // 19
        sp.GetRequiredService<IContentVersionOperationService>(), // 20
        sp.GetRequiredService<IContentMoveOperationService>(), // 21
        sp.GetRequiredService<IContentPublishOperationService>(), // 22
        sp.GetRequiredService<ContentPermissionManager>()));   // 23 - NEW Phase 6

Step 2: Verify the registration compiles

Task 5: Delegate Permission Methods to ContentPermissionManager

Files:

  • Modify: src/Umbraco.Core/Services/ContentService.cs

Step 1: Replace SetPermissions implementation with delegation

Find the #region Permissions section and replace the method implementations:

Before:

public void SetPermissions(EntityPermissionSet permissionSet)
{
    using (ICoreScope scope = ScopeProvider.CreateCoreScope())
    {
        scope.WriteLock(Constants.Locks.ContentTree);
        _documentRepository.ReplaceContentPermissions(permissionSet);
        scope.Complete();
    }
}

After:

public void SetPermissions(EntityPermissionSet permissionSet)
    => PermissionManager.SetPermissions(permissionSet);

Step 2: Replace SetPermission implementation with delegation

Before:

public void SetPermission(IContent entity, string permission, IEnumerable<int> groupIds)
{
    using (ICoreScope scope = ScopeProvider.CreateCoreScope())
    {
        scope.WriteLock(Constants.Locks.ContentTree);
        _documentRepository.AssignEntityPermission(entity, permission, groupIds);
        scope.Complete();
    }
}

After:

public void SetPermission(IContent entity, string permission, IEnumerable<int> groupIds)
    => PermissionManager.SetPermission(entity, permission, groupIds);

Step 3: Replace GetPermissions implementation with delegation

Before:

public EntityPermissionCollection GetPermissions(IContent content)
{
    using (ICoreScope scope = ScopeProvider.CreateCoreScope(autoComplete: true))
    {
        scope.ReadLock(Constants.Locks.ContentTree);
        return _documentRepository.GetPermissionsForEntity(content.Id);
    }
}

After:

public EntityPermissionCollection GetPermissions(IContent content)
    => PermissionManager.GetPermissions(content);

Step 4: Verify the file compiles

dotnet build src/Umbraco.Core/Umbraco.Core.csproj --no-restore

Expected: Build succeeds.

Step 5: Commit

git add src/Umbraco.Core/Services/ContentService.cs

Task 6: Add Phase 6 DI Test

Files:

  • Modify: tests/Umbraco.Tests.Integration/Umbraco.Infrastructure/Services/ContentServiceRefactoringTests.cs

Step 1: Verify using directive

The file should already have:

using Umbraco.Cms.Core.Services;  // ContentPermissionManager is here

v1.2 Change: ContentPermissionManager is in Umbraco.Cms.Core.Services namespace (same as other content services).

Step 2: Add Phase 6 test region

After the #region Phase 5 - Publish Operation Tests region, add:

#region Phase 6 - Permission Manager Tests

/// <summary>
/// Phase 6 Test: Verifies ContentPermissionManager is registered and resolvable from DI.
/// </summary>
[Test]
public void ContentPermissionManager_CanBeResolvedFromDI()
{
    // Act
    var permissionManager = GetRequiredService<ContentPermissionManager>();

    // Assert
    Assert.That(permissionManager, Is.Not.Null);
    Assert.That(permissionManager, Is.InstanceOf<ContentPermissionManager>());
}

/// <summary>

    ContentService.Save(content);

    var adminGroup = await UserGroupService.GetAsync(Constants.Security.AdminGroupAlias);
    Assert.That(adminGroup, Is.Not.Null, "Admin group should exist");

    // Act - This should delegate to ContentPermissionManager
    ContentService.SetPermission(content, "F", new[] { adminGroup!.Id });

    // Assert - Verify it worked (via GetPermissions which also delegates)
    var permissions = ContentService.GetPermissions(content);
    var adminPermissions = permissions.FirstOrDefault(p => p.UserGroupId == adminGroup.Id);

    Assert.That(adminPermissions, Is.Not.Null, "Should have permissions for admin group");
    Assert.That(adminPermissions!.AssignedPermissions, Does.Contain("F"),
        "Admin group should have Browse permission");
}

#endregion

Task 7: Run Phase Gate Tests

Step 1: Run the refactoring-specific tests

dotnet test tests/Umbraco.Tests.Integration --filter "FullyQualifiedName~ContentServiceRefactoringTests" --no-build

Expected: All tests pass, including:

  • The 4 existing permission tests (Tests 9-12)
  • The 2 new Phase 6 tests

Step 2: Run all ContentService tests

dotnet test tests/Umbraco.Tests.Integration --filter "FullyQualifiedName~ContentService" --no-build

Expected: All tests pass (no regressions).

Step 3: Document results

If any tests fail, follow the Regression Protocol from the design document:

  1. STOP - Do not proceed
  2. DIAGNOSE - Identify which behavior changed
  3. FIX - Restore expected behavior
  4. VERIFY - Re-run all tests
  5. CONTINUE - Only after all tests pass

Task 8: Final Commit and Tag

Step 1: Create final commit if not already done

git status
# If there are uncommitted changes, commit them

Step 2: Create git tag for Phase 6

git tag -a phase-6-permission-extraction -m "Phase 6 complete: ContentPermissionManager extracted"

Step 3: Update design document

Update /home/yv01p/Umbraco-CMS/docs/plans/2025-12-19-contentservice-refactor-design.md:

Change Phase 6 status from Pending to ✅ Complete:

| 6 | Permission Manager | All ContentService*Tests + Permission tests | All pass | ✅ Complete |

Add to Phase Details section:

6. **Phase 6: Permission Manager** ✅ - Complete! Created:
   - `ContentPermissionManager.cs` - Internal manager class (~50 lines)
   - Updated `ContentService.cs` to delegate permission operations
   - Git tag: `phase-6-permission-extraction`

Summary

Phase 6 extracts permission operations into an internal ContentPermissionManager class:

Task Files Changed Purpose
1 Create src/Umbraco.Core/Services/ContentPermissionManager.cs New internal manager class
2 Modify src/Umbraco.Core/DependencyInjection/UmbracoBuilder.cs Register manager in DI (AddScoped)
3 Modify src/Umbraco.Core/Services/ContentService.cs Add constructor parameter (position 23)
4 Modify src/Umbraco.Core/DependencyInjection/UmbracoBuilder.cs Update ContentService factory
5 Modify src/Umbraco.Core/Services/ContentService.cs Delegate methods to manager
6 Modify tests/.../ContentServiceRefactoringTests.cs Add DI verification tests
7 Run tests Verify no regressions
8 Tag and document Complete phase

v1.3 Note: All file paths are in Umbraco.Core, not Umbraco.Infrastructure. This matches Phases 1-5.

Expected Line Count Reduction: ~15 lines removed from ContentService (replaced with 3 one-liner delegations).

Risk Level: Low - Permission operations are simple, isolated, and have comprehensive test coverage.


v1.1 Changes Summary

Applied based on critical review 1 feedback:

Issue Resolution
File location Moved from Umbraco.Core to Umbraco.Infrastructure (REVERTED in v1.2)
ArgumentNullException pattern Changed to ThrowIfNull() for consistency with codebase patterns
Input validation Added null/empty checks for all method parameters
Logger usage Added LogDebug calls for security-relevant permission operations
Return type materialization Added documentation note that EntityPermissionCollection is materialized
Audit logging Deferred to optional future enhancement - LogDebug provides basic auditability

v1.2 Changes Summary

Applied based on critical review 2 feedback:

Issue Resolution
BLOCKING: File location REVERTED to Umbraco.Core/Services/ - the v1.1 Infrastructure placement was an architectural violation (Core cannot reference Infrastructure). All Phases 1-5 services are in Core.
DI registration using Updated to use Umbraco.Cms.Core.Services namespace
ContentService using Removed - same namespace, no using directive needed
Test using Uses existing Umbraco.Cms.Core.Services namespace
Permission validation Added LogWarning for non-single-character permission codes
Summary table Updated to reflect Core location

v1.3 Changes Summary

Applied based on critical review 3 feedback:

Issue Resolution
BLOCKING: Wrong DI file Tasks 2 & 4: Changed from Infrastructure/DependencyInjection/UmbracoBuilder.CoreServices.cs to Core/DependencyInjection/UmbracoBuilder.cs
BLOCKING: Wrong directory Confirmed file path is Services/ContentPermissionManager.cs (no /Content/ subdirectory)
High: Constructor order Added explicit numbering - ContentPermissionManager is parameter 23 (after publishOperationService)
High: Namespace Confirmed Umbraco.Cms.Core.Services throughout
Medium: AddScoped vs AddUnique Added design note explaining why AddScoped is appropriate for internal class
Minor: Commit messages Added Phase context to commit messages
Minor: Summary table Updated with full file paths

Execution Options

1. Subagent-Driven (this session) - I dispatch fresh subagent per task, review between tasks, fast iteration

2. Parallel Session (separate) - Open new session with executing-plans, batch execution with checkpoints

Which approach?
