Refactoring the creation of database schema and base/default data creation. Adding extension method to get all properties for interfaces in PetaPoco used for mapping. Creating ServiceContext and adding it to the UmbracoContext to provide access to the various services. Adding UmbracoContext to BaseDatabaseFactory test.

using NUnit.Framework;
Fixes ServiceContext to ensure the repo's are lazy instantiated because their ctor's rely on the RepositoryResolver.Current being initialized which normally doesn't occur until after the ServiceContext is constructed. Adds instance level caching for the GetRecursiveValue method in case this is called more than one time for a property in one view. Reverts PetaPocoUnitOfWork to allow more than one call to Commit().. this isn't 'best practices' per se but it is more for performance reasons because otherwise we'd have to create a new repo object + uow for any bulk saving operations... The end result is the same, bulk operations in the Services cannot be processed in one transaction. Fixing up the ContentServiceTests by ensuring that the shared and always open sqlce connection with the legacy SqlCeContextGuardian is closed on TearDown.

UmbracoSettings.UseLegacyXmlSchema = false;
Created RepositoryInstanceResolver/Factory to replace the configuration based instantiation of Repo's. Added unit tests to support resoling each instance, fixed CodeFirstTests to ensure that the base.TearDown() method is called. Changed the BaseMapper's to internal.
2012-12-09 09:01:00 +05:00
Changed all data services to create one repository type in the constructor instead of resolving them in each method since they are only supposed to be using their single unit of work anyways (resolving will return the same repository anyways, but in some cases it might have been with a different UOW) Removed SetUnitOfWork method on IRepository as this is not needed. Removed the old implementation of RepositoryResolver and replaces it with the RepositoryInstanceResolver (but maintained the name of RepositoryResolver)
