Matthias Radestock f80410bf59 switch to gossip broadcast for topology updates 2015-04-06 14:17:23 +01:00
Matthias Radestock f4416bfadc introduce Routes.EnsureRecalculated 
A means to ensure that any preceeding route recalculation requests
have been processed. It's akin to a global promise.

Matthias Radestock 6bc660068f use GossipSender for GossipBroadcast 
This makes GossipBroadcast properly async.

Matthias Radestock 8a2828d57d add "representation of received update" to return of Peers.ApplyUpdate 2015-04-06 14:17:23 +01:00
Matthias Radestock a58eb6ba7d make gossip broadcast operate on GossipData 2015-04-06 14:00:51 +01:00
Matthias Radestock 9b9d8a03aa refactor: make Peer.Connections() return a set instead of a slice 
This is more flexible since it allows callers to perform efficient
lookups on the result.

canonical sets

Matthias Radestock e8e9a43abd tired of typing "struct{}{}" 2015-04-06 11:53:51 +01:00
Matthias Radestock 6db12d682e make PeerNameSet a more broadly used type 2015-04-06 11:45:17 +01:00
Matthias Radestock 74b3f8d44e use map[...]struct{} for sets instead of map[...]bool 
See https://groups.google.com/d/msg/golang-nuts/lb4xLHq7wug/MhrSLkyS4F8J

We don't really care about the performance aspect of this, but using
struct{}{} values is in some way canonical since it means the
representation carries no redundant information.

Matthias Radestock 6f2f25aca5 don't complain in weave status about weavedns absence/errors

Matthias Radestock 4ebbdabfa1 never, ever use 10.0 for anything 
it has a high probability of conflicting
 2015-04-04 22:00:06 +01:00
Matthias Radestock 95c1e226f0 use routes based on tcp overlay connectivity for gossip 
i.e. include asymmetric and non-established connections
This is TRTTD since gossip flows over the tcp overlay.

Matthias Radestock 91ed22a953 refactor(ish): generalise an abstraction 
LocalPeer.NextBroadcastHops -> ConnectionsTo
thus separating the computation of who we want to connect to from
obtaining the associated Connections

Matthias Radestock fdea7d93f9 refactor: improve abstraction in connection gossip handling 
- turn previously free-floating functions into methods on GossipChannel
- move gossip message type dispatch from connection into router

Matthias Radestock 6f398a7459 refactor(ish): raise GossipSender abstraction level slightly 2015-04-03 18:33:59 +01:00
Matthias Radestock 7166d151aa make route calculcation more efficient and properly async 
Instead of following the usual actor pattern, we use a 1-place channel
with a non-blocking send. Essentially, if there is already a pending
recalculation request queued up, there is no point enqueuing another
one.

David Wragg 587a67d701 Comment 
It's not blindingly obvious where this 'found' comes from.

Matthias Radestock 5648f87717 oops 
broke this in 45740b1419
 2015-04-02 13:03:42 +01:00
Matthias Radestock 488c5c5a2d bump default connection limit to 30 
I can get 29 weaves running on my laptop, and once all connections are
established, the avg cpu load is ~10%. 30 runs into difficulty because
the concurrent connection establishment does create a very high load,
resulting in some timeouts. But that wouldn't happen when running each
weave in a separate machine (with more CPU resources overall than my
single laptop).

Stop gap solution for #426.

Matthias Radestock 24f3634254 pass WEAVE_CONTAINER_NAME to weavexec 2015-04-02 10:13:52 +01:00
Matthias Radestock ea3c5c5f90 introduce (undocumented) weave test-launch command 
which allows launching of several weave routers on the same machine,
by invoking this multiple times with different WEAVE_CONTAINER_NAMEs.

The routers are not connected to the bridge and do not perform any
capture/injection. So this is mainly intended for testing of
administrative and control plane functionality, rather than routing.

Move away from recursive go test, as it cannot output a merged coverage profile.
