A new ``auto`` value for the configuration option
|
|
|
|
``upgrade_levels.compute`` is accepted, that allows automatic determination
|
|
|
|
of the compute service version to use for RPC communication. By default, we
|
|
|
|
still use the newest version if not set in the config, a specific version
|

|
|
if asked, and only do this automatic behavior if 'auto' is
|
|
|
|
configured. When 'auto' is used, sending a SIGHUP to the service
|
|
|
|
will cause the value to be re-calculated. Thus, after an upgrade
|
|
|
|
is complete, sending SIGHUP to all services will cause them to
|
|
|
|
start sending messages compliant with the newer RPC version.
