  1. # Replace master locks and monitor locks with C Threads mutex variables.
  2. # In the kernel replace event-based waiting with waiting on C Threads
  3. # condition variables.  
  4.  
  5. # For user locks and condition variables, we would like to maintain binary
  6. # compatibility with existing Sprite code.  This could get ugly, though, given
  7. # that we want to ditch the event-based internals.  So, we'll punt on binary
  8. # compatibility (which should be okay, since there are very few programs that
  9. # use Sprite synchronization calls) and change Sprite primitives to C Threads
  10. # primitives (in some almost source-compatible way).  The "almost" refers to
  11. # not supporting the "wakeup on signal" flag.  We will assume this flag isn't
  12. # required by user programs and deal with problems that occur if this
  13. # assumption is wrong (hopefully by fixing the user code).
  14.  
  15. # There will also be a general per-process condition variable that can be used
  16. # for waiting on remote hosts.  This will also be the condition variable that
  17. # replaces the PCB address in the event-based code.
  18.  
  19. # For signals, probably don't need extra bits in proc syncFlags.  Instead,
  20. # just check when the process comes back from the context switch whether
  21. # there's a signal pending.  This does introduce a race condition, in case a
  22. # signal happens at about the same time the condition is woken up: you won't
  23. # know which event actually caused the wakeup to occur.  But do you care?
  24. # (The alternative is to add a "wakeup on signal" bit and a "was woken by
  25. # signal" bit to the proc syncFlags.)
  26. # Add a field pointing to the condition that the process is
  27. # waiting on.
  28.  
  29. LOCK_MONITOR            # keep.
