--------------------------------------------------
> Shindig bootstrap service/composite code smells and is incomprehensible
> -----------------------------------------------------------------------
>
> Key: AMDATUOPENSOCIAL-55
> URL: http://jira.amdatu.org/jira/browse/AMDATUOPENSOCIAL-55
> Project: Amdatu OpenSocial
> Issue Type: Improvement
> Reporter: Bram de Kruijff
> Assignee: Ivo Ladage - van Doorn
> Fix For: 0.2.0
>
>
> This is about how the OpenSocial shindig bundle bootstraps its services. Just
> logging this because I ran into it while refactoring HttpContext and got into
> a deadlock caused by a lock in a a callback. Took me an hour to get some
> understanding of what is happening. My initial suggestion would be to change
> the GuiceInjectorServiceImpl part from service to simple delegate to
> ShindigRegistrationServiceImpl removing the need for complex orchestration
> through service dependencies.
> 01. Activator adds Component GuiceInjectorService|GuiceInjectorServiceImpl to
> DepManager
> 02. DepManager starts GuiceInjectorService!GuiceInjectorServiceImpl#instance
> (1st time on instance)
> 03. Activator adds Component
> ResourceProvider,ShindigService|ShindigRegistrationServiceImpl to DepManager
> 04. DepManager injects GuiceInjectorService|GuiceInjectorServiceImpl#instance
> into ShindigRegistrationServiceImpl
> 05. DepManager inits ShindigRegistrationServiceImpl (seems previsous step
> always in time...?)
> 06. ShindigRegistrationServiceImpl.init() add Component
> Servlet|GuiceInjectorServiceImpl#instance to DepManager
> 07. DepManager does starts Servlet|GuiceInjectorServiceImpl#instance (2nd
> time on instance)
> 08. DepManager does callback to DispatcherService.servletAdded with
> Servlet|GuiceInjectorServiceImpl#instance
> 09. DispatcherService does init(ServletConfig) on
> Servlet|GuiceInjectorServiceImpl#instance
> 10. Servlet|GuiceInjectorServiceImpl#instance.init(ServletConfig) adds
> Component GuiceInjectorServlet!GuiceInjectorServiceImpl#instance
> 11. DepManager starts GuiceInjectorServlet!GuiceInjectorServiceImpl#instance
> (3rd time on instance)
> 12. DepManager injects GuiceInjectorServlet!GuiceInjectorServiceImpl#instance
> into ResourceProvider,ShindigService|ShindigRegistrationServiceImpl
> 13. DepManager starts
> ResourceProvider,ShindigService|ShindigRegistrationServiceImpl
> 14. ResourceProvider,ShindigService|ShindigRegistrationServiceImpl ads
> several Components for servlets
> 15 DepManager does callback to DispatcherService.servletAdded for previsous
> step
