Semaphore Equivalent

Question Text​

From running and inspecting the code in support/apache2-simulator/apache2_simulator_semaphore.py, which of the following is an an equivalent to the value of the semaphore sem?

Question Answers​

  • The value of msg_mutex

  • The time a worker thread has to wait before running

  • The length of the messages list
  • The number of worker threads

sem is incremented (release()) upon adding a message to the messages list and decremented (acquire()) when removing a message from said list. So it's a rough equivalent to the length of this list.
