Message:

major re-work of the threading / thread-locking design:

1) drop the input thread
2) merge job and task threads
3) define locks for:

  • Command : ops that use the opihi command parser and related
  • Client : ops to manage client connections
  • Control : ops that manipulate the controller elements
  • JobTask : ops that manipulate the Job and/or Task lists

The old threading / locking effectively serialized all operations,
except for client command; however the client and other ops that used
the opihi parse could collide. the new model allows for more parallel
operations, and prevents these thread conflicts.

     34  We've been surviving with a slightly broken threading / locking
     35  model.  I would like to clean it up.  Previously, the threads where
     36  blocking at a very coarse level, and there were certain interactions
     37  that were not thread-safe.  Here are my notes on re-working this:
     38
     39  * we have 6 threads:
     40
     41    * main (top-level parent) : after it spawns the 5 child threads,
     42      this thread waits for new clients and adds them to the list of
     43      active clients with 'AddNewClient'
     44
     45    * clientsThread (ListenClients): this thread is listening for
     46      commands from the clients; when it receives a complete command,
     47      it executes the command using 'multicommand'.
     48
     49    * tasksThread
     50      CheckTasks
     51        NextTask
     52
     53
     54
     55    * jobsThread
     56
     57    * controllerThread
     58      CheckControllerStatus : race condition is irrelevant
     59
     60    * inputsThread
     61      AddNewInput called by clientThread
     62      (not sure this is really being used:
     63           server input (filename) calls 'input'
     64           server module (filename) calls 'module'
     65
     66  * functions which need to be thread-safe:
     67    * AddNewClient
     68    * gprint and supporting functions must be thread safe (extensively
     69      used...)
