kaiyou 5b6923c272 Unexporter AssignOverlayAddress 
Instead, the overlay address is assigned upon creation.
Also, the wireguard state is responsible for populating
the local node object.
 2020-05-13 13:52:54 +02:00
kaiyou c50011bc36 Use errors.Wrap instead of manual formatting 2020-05-13 13:52:54 +02:00
kaiyou 32a300ffeb Rename node.Decode and node.Encode 
EncodeMeta and DecodeMeta are more explicit.
 2020-05-13 13:52:54 +02:00
kaiyou 078946dbdd Use localNode to store the local node name 
Also rename setupDelegate to SetLocalNode, so that
main can call SetLocalNode then Update().
 2020-05-13 13:52:54 +02:00
kaiyou 28a31efc1f Rename saveState to state.save 2020-05-13 13:52:54 +02:00
kaiyou d85fb84398 Unexport state from the cluster package 2020-05-13 13:52:54 +02:00
kaiyou 9ddcbb7914 Apply suggestions from code review 
Review suggestions in the documentation

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.
 2020-05-13 13:52:54 +02:00
kaiyou f715cfa787 Remove the unneeded writeToEtcHosts function 2020-05-13 13:52:54 +02:00
kaiyou 61104a9272 Add some comments to the main function 2020-05-13 13:52:54 +02:00
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.
 2020-05-13 13:52:54 +02:00
kaiyou 5d1acc1fab Add documentation to public functions and types 2020-05-13 13:52:54 +02:00
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.
 2020-05-13 13:52:54 +02:00
kaiyou 13e1515f7d Split cluster into multiple files 2020-05-13 13:52:54 +02:00
kaiyou 622cfce1ad Add unit tests for node encoding/decoding 2020-05-13 13:52:54 +02:00
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().
 2020-05-13 13:52:54 +02:00
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 b0bfeb1f8e Move the metadata parsing code to node.go 2020-05-13 13:52:54 +02:00
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.
 2020-05-13 13:52:54 +02:00
kaiyou 5772640cf9 Fix a simple typo 2020-05-13 13:52:54 +02:00
kaiyou f2e53dd869 Lower the complexity of newCluster() 
Move the computation of clusterKey and bindAddress
to separate functions.
