> Issue Type: Bug
> Reporter: Sebastian Schaffert
> Assignee: Sebastian Schaffert
> Priority: Minor
>
> In the default Sesame SailRepositoryConnection, the getValueFactory() method
> returns the value factory of the SailRepository. In KiWi this is a bit
> problematic, because the value factory needs a database connection for
> loading nodes when needed. When someone uses the getValueFactory() method,
> this means that there will be two database connections open, which can be a
> problem for several reasons:
> - transaction isolation (database): nodes created in the one connection are
> not yet available in the other
> - connection leakage: the value factory connection managed by the KiWiStore
> will only be closed on shutdown(); if someone forgets a proper shutdown, this
> can result in connection leakage
> The solution would be to implement a custom version of SailRepository and
> SailRepositoryConnection which directs the getValueFactory() to the value
> factory of the SailConnection.
