I've provided a merge proposal which works with both single and multiple
processes. I think that this is a good long-term solution that keeps the
same functionality as we have now. Could you take a look at that and
merge it if you agree?

The first workaround that you have suggested still has problems due to
the GIL. The merge proposal that I've provided gets around this.

Thanks

James

Title:
  Scheduler is not working when OpenERP is running with gunicorn

Status in OpenERP Server:
  Confirmed

Bug description:
  The OpenERP scheduler ois not working correctly in version 6.1 when
  OpenERP is running using gunicorn. In the initial investigations that
  I've done I think that the problem is because each gunicorn worker is
  running in a separate thread, so the memory space is different.
  OpenERP is designed to be stateless, so this should be fine. However,
  in the case of the scheduler, tasks are being pushed and popped from
  the heap... which will be different for each process.

  I think that a more robust solution would be add the tasks to the
  database and the cron Master Thread process would read from the
  database (instead of the heap).

  This is straightforward to verify: create some scheduled actions that
  are due to be run (there are some in the system by default) and start
  OpenERP using gunicorn. You should see that the scheduled actions
  aren't run. Then compare what happens when OpenERP is started in a
  single-threaded manner e.g. ./openerp-server -d dbname. This time
  you'll see that the schedule actions are run.
