Reino: Time and State

A computação distribuída consiste em tempo e estado. Isto é, para que mais de um componente se comunique, é necessário compartilhar o estado, o que exige tempo.

A maioria dos programadores antropomorfiza seu trabalho. Eles enxergam um thread de controle executando todo o programa da mesma forma como enxergariam a si mesmos fazendo o trabalho inteiro por conta própria. Computadores modernos, entretanto, alternam entre tarefas com muita rapidez e, em sistemas multi-core, multi-CPU ou distribuídos, dois eventos podem ocorrer exatamente ao mesmo tempo. Defeitos rapidamente são postos nas lacunas entre o modelo do programador de como um programa é executado e o que ocorre na realidade. Esses defeitos estão relacionados com interações inesperadas entre threads, processos, tempo e informações. Essas interações ocorrem por meio de estados compartilhados: semáforos, variáveis, o sistema de arquivos e, basicamente, todas as coisas capazes de armazenar informações.

Race Condition: Roaming Data Access

C#/VB.NET/ASP.NET

Abstract

O desenvolvedor está usando a propriedade RoamingFolder ou RoamingSettings da classe Windows.Storage.ApplicationData.

Explanation

As propriedades RoamingFolder e RoamingSettings obtêm um contêiner no repositório de dados do aplicativo em roaming, que pode então ser usado para compartilhar dados entre mais dois dispositivos. Ao gravar e ler objetos armazenados no repositório de dados do aplicativo móvel, o desenvolvedor aumenta o risco de comprometimento. Isso inclui a confidencialidade, a integridade e a disponibilidade dos dados, aplicativos e sistemas que compartilham esses objetos por meio do repositório de dados em roaming.

Os desenvolvedores devem evitar o uso dessa funcionalidade sem primeiro implementar os controles técnicos necessários.
