[Question] Is there any way to force reload authorization provider during runtime?

Assume the following authorization provider:

namespace Languages.Authorization
{
    public class LanguagesAuthorizationProvider : AuthorizationProvider
    {
        public override void SetPermissions(IPermissionDefinitionContext context)
        {
            using (var scope = IocManager.Instance.CreateScope())
            {
                var _permissionProvider = IocManager.Instance.Resolve<IPermissionManager>();
                var _langManager = IocManager.Instance.Resolve<ILanguageManager>();

                var administration = context.CreatePermission(PermissionNames.Administration);
                var languages = administration.CreateChildPermission(PermissionNames.Administration_Languages);
                languages.CreateChildPermission(PermissionNames.Administration_Languages_Create);
                languages.CreateChildPermission(PermissionNames.Administration_Languages_Read);
                languages.CreateChildPermission(PermissionNames.Administration_Languages_Update);
                languages.CreateChildPermission(PermissionNames.Administration_Languages_Delete);
                languages.CreateChildPermission(PermissionNames.Administration_Languages_List);

                var languageTexts = languages.CreateChildPermission(PermissionNames.Administration_Languages_Texts);
                languageTexts.CreateChildPermission(PermissionNames.Administration_Languages_Texts_List);
                var languageTextsUpdate = languageTexts.CreateChildPermission(PermissionNames.Administration_Languages_Texts_Update);
                var LanguageTextsRead = languageTexts.CreateChildPermission(PermissionNames.Administration_Languages_Texts_Read);


                foreach (var lang in _langManager.GetLanguages())
                {
                    languageTextsUpdate.CreateChildPermission($"{PermissionNames.Administration_Languages_Texts_Update}.{lang.Name}");
                }

                foreach (var lang in _langManager.GetLanguages())
                {
                    LanguageTextsRead.CreateChildPermission($"{PermissionNames.Administration_Languages_Texts_Read}.{lang.Name}");
                }


            }
        }

Now a new language is added but permissions provider is not aware of newly added language. Is there a way to force Authorization to reload permissions? It is somehow related to #3538 but the difference here is that permissions usage is predicted during design time: see for example part of LocalizationTextsAppService:

  public async Task AddEditTranslation(LanguageTextsInput input)
        {
            
            await PermissionChecker.AuthorizeAsync(PermissionNames.Administration_Languages_Texts_Update + "." + input.Language);
            if (input.Value == null) input.Value = "";
            await _langTextsManager.UpdateStringAsync(null, input.Source, new System.Globalization.CultureInfo(input.Language), input.Key, input.Value);
        }

For development i can easily restart app pool, but this is not an option to a highly traffic web app due to app pool warm up

@raphaeldiasrj today i was facing this issue and just made this solution up you can try it i’m still in the middle of project building and it’s working fine with me

1. I copied this files and pasted them in my project (PermissionDefinitionContextBase , PermissionDictionary,PermissionManager).

2. In my Core Module in PreInitialize()

//Added this Handler so i can redirect every IPermissionManager to my Custom Implementation
            IocManager.IocContainer.Kernel.AddHandlerSelector(new PermissionManagerHandler());

And The PermissionManagerHandler

public class PermissionManagerHandler : IHandlerSelector 
    {      
        public bool HasOpinionAbout(string key, Type service)
        {
            return typeof(IPermissionManager) == service;
        }
        public IHandler SelectHandler(string key, Type service, IHandler[] handlers)
        {
            return handlers.First(x => x.ComponentModel.Implementation == typeof(PermissionManager));
        }
    }

1. In Custom Permission Manager i Modified the Initialize Function by adding
   Permissions.Clear(); then every time i add a new Permission i call the initialize function so i can republish every thing

2. in Core Module PostInitilize Method add IocManager.Resolve<PermissionManager>().Initialize();

@tamys : Did @AhmedGoGo’s solution work? I have tried but faced the error “No component for supporting the service Abp.Authorization.PermissionManager was found”. Could you share some advices?

Try to change the Namespace of the copied files to yours instead of Abp.Authorization

and be sure that the copied PermissionManager implements ISingletonDependency
