Renames `config` to `generate-config` and implements a new `config`
command that generates the configuration file based on the current
state instead of printing a static string.
Primary message interface is the MessageBroker which is an attribute of the Messenger.
MessageBroker implementations:
- Gossip (memberlist)
- Broadcast (uses HTTP, received by existing Handler)
- Static (no-ops)
Changes CacheSize from `int` to `uint32` for consistency with protobuf.
Removes unnecessary dependencies in glide:
- `github.com/aws/aws-sdk-go`
- `golang.org/x/net` (although this gets included by memberlist)
TODO:
- [ ] Add tests around the Messenger and MessageBroker objects.
- [ ] Refactor CreateSliceMessage to work with views.
- [ ] Support propogation of meta data on PATCH calls.
fixing some issues from last rebase
Changes Gossiper to NodeSet.
Adds StaticNodeSet (for testing) and GossipNodeSet (for memberlist) implementations.
Changes NodeSet interface to return a pilosa-specific generic instead of `NodeSet interface`.
Removes NumMembers from interface (which is specific to memberlist).
Implements a Messenger interface with which to send inter-node messages via NodeSet.
The Pilosa implementation occurs in the GossipNodeSet.
Implements the Messenger as an object on Server, Handler, and Index.
Uses HealthStatus constants.
Removes commented-out code.
for gossip, make sure to bind to both host and port, and advertise those as well
adjust messenger to work with the db schema logic
add dependencies: hashicorp/memberlist, golang.org/x/sync
add dependency: golang.org/x/net
Uses `errgroup` to handle errors from broadcast messages.
Marshals message one time instead of once for every node.
Adds error handling for some errors that were being swallowed.
