! d3web Sessions in Multi-Threaded Environments
At line 131 changed one line
In general a single d3web session is not thread-safe for write access. Reading the session contents from multiple threads is ok. But having an applications where multiple threads simultaneously read/write to a session, they need to be synchronized Even if there is only one thread that writes to the session, it need to be synchronized with all reading threads. By convention, in d3web this should be done using the "Session"-Object as the semaphore for synchronization. This makes sure that your code will be interoperable with all other applications code (also considering this convention), without being in danger to create deadlocks.
! Are d3web's Session objects thread-safe for multi-threaded environments?
