V9: Send content type notifications on copy

[nikolajlauridsen]

This PR migrates #12330 to V9, adding the missing content type events when copying:

• MemberTypes
• DocumentTypes
• MediaTypes

These missing events are:

• Saving
• Changed
• Saved

Testing

Add notifications handlers the the expected event and try and copy the different content types.

I used this notification handler and put a breakpoint on each handle method:

using Microsoft.Extensions.Logging;
using Umbraco.Cms.Core.Composing;
using Umbraco.Cms.Core.DependencyInjection;
using Umbraco.Cms.Core.Events;
using Umbraco.Cms.Core.Notifications;

namespace Umbraco.Cms.Web.UI
{
    public class TestHandler :
        INotificationHandler<MemberTypeSavedNotification>,
        INotificationHandler<MemberTypeChangedNotification>,
        INotificationHandler<MemberTypeSavingNotification>,
        INotificationHandler<ContentTypeSavedNotification>,
        INotificationHandler<ContentTypeSavingNotification>,
        INotificationHandler<ContentTypeChangedNotification>,
        INotificationHandler<MediaTypeSavedNotification>,
        INotificationHandler<MediaTypeChangedNotification>,
        INotificationHandler<MediaTypeSavingNotification>
    {
        private readonly ILogger<TestHandler> _logger;

        public TestHandler(ILogger<TestHandler> logger) => _logger = logger;

        public void Handle(MemberTypeSavingNotification notification) => _logger.LogInformation("Member type saving notification received");

        public void Handle(MemberTypeChangedNotification notification) => _logger.LogInformation("Member type changed notification received");

        public void Handle(MemberTypeSavedNotification notification) => _logger.LogInformation("Member type saved notification received");

        public void Handle(ContentTypeSavingNotification notification) => _logger.LogInformation("Content type saving notification received");

        public void Handle(ContentTypeChangedNotification notification) => _logger.LogInformation("Content type changed notification received");

        public void Handle(ContentTypeSavedNotification notification) => _logger.LogInformation("Content type saved notification received");

        public void Handle(MediaTypeSavingNotification notification) => _logger.LogInformation("MediaTypeSavingNotification received");

        public void Handle(MediaTypeChangedNotification notification) => _logger.LogInformation("Media type changed notification received");

        public void Handle(MediaTypeSavedNotification notification) => _logger.LogInformation("Media type saved notification received");

    }

    public class TestHandlerComposer : IComposer
    {
        public void Compose(IUmbracoBuilder builder) =>
            builder
                .AddNotificationHandler<MemberTypeSavedNotification, TestHandler>()
                .AddNotificationHandler<MemberTypeChangedNotification, TestHandler>()
                .AddNotificationHandler<MemberTypeSavingNotification, TestHandler>()
                .AddNotificationHandler<ContentTypeSavedNotification, TestHandler>()
                .AddNotificationHandler<ContentTypeChangedNotification, TestHandler>()
                .AddNotificationHandler<ContentTypeSavingNotification, TestHandler>()
                .AddNotificationHandler<MediaTypeSavedNotification, TestHandler>()
                .AddNotificationHandler<MediaTypeChangedNotification, TestHandler>()
                .AddNotificationHandler<MediaTypeSavingNotification, TestHandler>();
    }
}
