Bryan Boreham 61b0d0ba9e Merge pull request #2149 from weaveworks/stop-test-router 
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 
Closes #2058.

Adam Harrison bceabe32a2 Try all pending allocations 
We can have outstanding allocations for different ranges owned by
different peers, so we should not short circuit after the first space
request.

Bryan Boreham e468399616 Extend the timeout for dead containers to 30 seconds, 
but remove them if they are destroyed, to reduce starvation
when users are creating and destroying containers quickly.

Bryan Boreham f84b933d7c Leave container allocations for a time after death

Bryan Boreham 4672e9ec1f Generalise ticker so we can use it for more than paxos,

Matthias Radestock 274265f001 typo 2015-12-21 17:03:03 +00:00
Matthias Radestock 3cd199e852 make GossipData immutable 
The same piece of GossipData can be shared and subject to different
Merge operations. We either need to copy the data when we share it, or
create copies on modification, i.e. copy-on-write.

We choose the latter, since it is more efficient and there is just one
mutating operation.

Fixes #1697.

Matthias Radestock dc9f8762ca move generic communication substrate into its own 'mesh' package 
This is mostly a matter of moving some files, changing package names,
changing some imports, and changing some type references.

We duplicate the odd constant & global var, and the intmac/macint
functions, since neither 'router' or 'mesh' nor, really,' common' are
a natural home for them.

Matthias Radestock 8bd77c0d47 refactor: get rid of router/utils.go 
most functions end up in other files in the router package, but a few
land in common.
