A remote Rails application (such as a Bourreau)
is currently stopped by sending it a signal (SIGTERM
by default) from an external process (the ruby script
cbrain_remote_ctl when remote control is configured).
A new command 'stop_yourslf' on the control channel
could do the trick even more cleanly: the remote
resource receiving it could:

  • stop its workers
  • stop the SSH master channels for the data providers
  • stop the SSH master channels for the
  • Bourreaux (N/A for the Bourreaux themselves)
  • send itself a TERM signal using spawn_fully_independent()

Although cleaner, I feel this is a low-priority back-end improvement which can be administered manually (as we do currently).

Several fixes all bundled together.
13718d5 
1- The controls channel for Bourreau has a new 'StopYourself'
   command, which is much more efficient than the old way
   of stopping the rails app using an external script.
   Fixes aces#55 .
2- The 'ibc' utility provides access to it with the 'J' command
3- Tooltips in the interface could never be positioned
   at offset_x set to 0 because 0 is falsy in javascript. Fixed.
4- We no longer ever keep a backup of database.yml on remote sites.
5- Userfiles viewers that have conditions which crash no
   longer prevent the 'show' page from rendering; instead the
   viewer is ignored and removed from the available list.
   Fixes aces#25
6- Task forms for boutiques tasks will present list
   inputs in proper order.
   Fixes aces#830
7- Support for lists for File inputs in boutiques
   Fixes aces#831
