* Module name changed to `github.com/rajch/weave`
* Added environment variable `CHECKPOINT_DISABLE=1` to default manifests, to bypass weaveworks telemetry
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.
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.
- Abide by gossip interface (return nil, not empty gossip) so gossip converges!
- Make sure we don't say an old entry version is new to us; add some more tests.
- Add dns test for 3 (or N) hosts
- Extend mock gossip router to ensure reconsumption off diffs yield nil
- Don't increment version when re-adding existing entry.
- Nameserver holds a sorted list of (hostname, peer, container id, ip) tuples.
- Entries are gossiped using topology gossip / broadcast - only new/updated entries
are propogated as expected.
- Entries for a given peer are removed when the connection to the peer is lost.
- Entries are tombstoned when containers die. Tombstones are kept for 10mins,
as they do not need to survive partition, only gossip propagation delay.
