kaiyou 129291e848 Use interface name instead of cluster name 
The cluster name option is not required anymore and
removed, the interface name is used to name the cluster
directly. For backward compatibility, the old path for storing
cluster state is tried as a fallback when loading.

kaiyou f1de2def7f Add Banner and StatePath settings 
Banner is used to carry a custom etc/hosts banner while StatePath holds
the path to cluster state storage.

kaiyou 61988692a1 Parse arguments in the tests entrypoint 
Add an argument parsing routine to the tests entrypoint, and use it
to parse the interface name, passed to
wireguard-go.

This is a temporary fix until the state path is made
configurable.

kaiyou e9b9239eae Reinstante cluster.LocalNode 
This makes for more straightforward calls. Also, generate
the localNode directly in wg.New.

kaiyou 5b6923c272 Unexporter AssignOverlayAddress 
Instead, the overlay address is assigned upon creation.
Also, the wireguard state is responsible for populating
the local node object.

kaiyou 32a300ffeb Rename node.Decode and node.Encode 
EncodeMeta and DecodeMeta are more explicit.

kaiyou 078946dbdd Use localNode to store the local node name 
Also rename setupDelegate to SetLocalNode, so that
main can call SetLocalNode then Update().

kaiyou faf1c35d96 Implement the delegate interface on Node 
Implementing on Node makes a bit more sense than implementing on Cluster
even if the difference in code is insignificant.

kaiyou b0e41d5c35 Rename WgState to State and NewWgState to New 
This also caused renaming local variables to avoid
conflicting with the wg package name itself.

kaiyou 3a882eb112 Generate the local node directly in main.go 
Instead of using a trivial function, simply generate the
local node from main.go, manually assign fields from the
nodeMeta struct.
 2020-05-13 13:52:54 +02:00
kaiyou 0162f9da2c Add unit tests for state functions 
Currently unit tests only succeed if the state path
is writeable, since it is hardcoded.

kaiyou 46da51b7aa Implement node function as type functions 
This means nodeMeta can be private again, and also makes it
easier to pass a Node object to the cluster for local meta,
instead of a generic byte[] function.

For later updating, that node is passed using Update() instead
of New().

kaiyou dadfbee083 Split the application into modules 
Splitting into modules will help keep concerns separate,
at the cost of a slightly more verbose code.

kaiyou 0e799d6074 Parse metadata outside of cluster.go 
Move the calls for metadata decoding from the cluster
membership management loop to the main loop. This task
was not directly related to the cluster, and was adding
complexity, including the need for multierr structures.
 2020-05-13 13:52:54 +02:00
kaiyou 366f906d5d Do not pass the config object to newCluster 
Decouple the config structure from the cluster management and
stop passing the config object around.
 2020-05-13 13:52:54 +02:00
kaiyou 97525f4b10 Stop using wireguard in cluster.go 
The wireguard is mostly used to compute metadata.
Metadata is now computed by main.go and encoded in
node.go, the cluster only receives a function generating
the binary metadata.
 2020-05-13 13:52:54 +02:00
kaiyou 0d93439d0d Move node related stuff to node.go 
The cornerstone for exchanging data is the node
structure and associated metadata. Moving it to a
separate file (maybe later a separate module) will help
decoupling.
