java - Do @SessionScoped beans have concurrency issues? -


obviously, it's easy have multiple parallel requests accessing same @sessionscoped bean in web app context. correct in believing have explicitly control synchronization when accessing @sessionscoped bean within requests?

depends on mean by:

explicitly control synchronization when access @sessionscoped bean within requests

you right there may several threads accessing @sessionscoped bean in parallel. have take care of thread safety. whether need explicitly control synchronization (or synchronize @ all) depends on how shared state used or modified different threads. if use classes java.util.concurrent or java.util.concurrent.atomic, may achieve perfect thread-safety without single synchronized statement.

but yes, have take care of thread safety.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
