Bryan Boreham 39ac1a0037 Collect existing weave addresses at start-up, to avoid a race when 
doing it from the script

Note we need to run weaver in the host pid namespace, so it can search
for existing container IPs. Also now we are firing off sub-processes
it's better to not be PID 1 so Linux doesn't expect us to reap zombies.

Matthias Radestock 27632b118f prevent excessive ring fragmentation due to repeated space requests 
Merging a ring now indicates whether the ring has been updated. This
prevents excessive allocation retries, which in turn can result in
repeated space requests - i.e. if an allocation cannot proceed due to
lack of space - which in turn can result in excessive ring
fragmentation since many of the requests will result in the creation
of a new ring entries, due to the need to split ranges.

Fixes #2181.

Matthias Radestock c0c5906d07 fix simulation of periodic gossip in TestTransfer 
`GossipBroadcast` in the `TestRouter` only goes one hop. In
`TestTransfer` the three peers are connected in a chain, and hence we
need to take extra care to ensure propagation to all peers.

Fixes #2180.

Bryan Boreham f84b933d7c Leave container allocations for a time after death 
so they will be reclaimed if the container is restarted.
Still cancel pending operations immediately a container dies
 2016-01-12 14:38:44 +00:00
Matthias Radestock 751ccd02f6 don't stall in ipam on early container death 
When a container died before we got into the allocation code (inside
the allocator run loop) we would not cancel the allocation since the
container death event will have been processed by the allocator before
it had any knowledge of the container.

The fix is to move the container-aliveness check inside the allocation
code. That way we still detect the death even if the event has already
flown past.

We only need to perform the check once, since any subsequent death
will result in an event that is processed by the allocator when it has
recorded the container in its state.

Fixes #1459.
