Bryan Boreham cda1084777 Check validity of IP subnets 
Be more consistent about this - check in the same way whether at startup
or during allocation.

Bryan Boreham 6847a3551d Persist the ring in Shutdown() and AdminTakeoverRanges(). 
Also make AdminTakeoverRanges cause pending ops to be retried.

Bryan Boreham 8405e0759a Clarify the function of the periodic ticker. 
- it either retries for consensus or retries operations we would have tried previously.
There is no point retrying pending operations if we are waiting for consensus.

Bryan Boreham fb3ed9c1a6 Re-organise checking of persisted data so the failure paths bail out 
of the function first.
Also bail out if there is no persisted ring, since persisted 'owned'
data isn't meaningful in that state.

Bryan Boreham 61fc5d56fb Refactor: move initialisation in the case that we don't use persisted data

stop ipam tests from leaking routers
 2016-04-11 13:34:21 +01:00
Matthias Radestock 695babf7ba make Allocator.Stop() idempotent and non-blocking 
So that tests don't have to be careful about ensuring that allocators
are stopped exactly once, or rely on the magic mesh.ChannelSize for
non-blocking behaviour.

Bryan Boreham ecf1887e5b Initialize Paxos quorum to 0 until this node needs to request consensus. 
With a 0 quorum we will participate in voting, but will not actively
try to form a ring.

Adam Harrison e9081c6607 Allow specification of initial IPAM ring via --ipam-seed 2016-03-21 09:49:54 +00:00
Matthias Radestock 9f10b21c9c use Space.NumFreeAddresses for calculating transferred ip count 
...rather than Space.NumFreeAddressesInRange; we don't care about the
universe.

Alternatively we could make Space.AddRanges return the count. But
AddRanges doesn't know whether the ranges overlap with existing free
space - that is only guaranteed by the context - so would have to do
much the same before/after calculation.

Another alternative would be to add the range sizes in
AdminTakeoverRanges. But that is more code and less clear.

Matthias Radestock 62d823850c make rmpeer report on size of transferred space, and not fail

We can have outstanding allocations for different ranges owned by
different peers, so we should not short circuit after the first space
