UnitOfWork: How to rollback and keep the logs

Question

I have a method as below:

using (var unitOfWork = _unitOfWorkManager.Begin())
{
    var result = await ExcuteOperator(input);
    if (!result.WorkflowStatus) 
    {
        unitOfWork.Dispose();
    }
    unitOfWork.Complete();
}


public async Task<ExecuteOperatorOutput> ExcuteOperator(ExecuteOperatorInput input)
{                  
    //Doing something
    DoSomething(input);

    //Insert log
    await _logRepository.InsertAsync(logInput);

    //Recursive
    return await ExcuteOperator(input);
}

My question is: How to rollback the unitOfWork manually without throw exception before unitOfWork.Complete() and keep the inserted logs?

Answer 1

There is no way to rollback the unitOfWork manually.

See rationale/attempts: https://github.com/aspnetboilerplate/aspnetboilerplate/issues?q=rollback

That said, an interested reader is welcome to attempt and solve the issues.

How to keep the logs after the transaction rolled back?

Begin a new unitOfWork that gets completed:

public async Task<ExecuteOperatorOutput> ExcuteOperator(ExecuteOperatorInput input)
{                  
    //...

    using (var unitOfWork = _unitOfWorkManager.Begin(TransactionScopeOption.RequiresNew))
    {
        await _logRepository.InsertAsync(logInput);
        unitOfWork.Complete();
    }

    //...
}
