Hi all,
I'm curious if there is a reason why there is before_resync_target but
not before_resync_source. Probably the rationale is that noone needed it
before :)
Background: the current capabilities to configure resync order or number
of resyncs per machine is doable either via manual pause-sync actions,
or via the syncer's '--after' parameter. However, in environment where
this is dynamic, it's hard to create a static map, and it would be
useful to have such a before_resync_source action that the helper can
act on - e.g. to pause the minor, to set its sync speed based on current
machine status, etc.
So… would it make sense to send a patch adding these two actions
(before/after)?
thanks,
iustin
