Remove Kademlia dependencies from Satellite and Storagenode (#2966)
What:

cmd/inspector/main.go: removes kad commands
internal/testplanet/planet.go: Waits for contact chore to finish
satellite/contact/nodesservice.go: creates an empty nodes service implementation
satellite/contact/service.go: implements Local and FetchInfo methods & adds external address config value
satellite/discovery/service.go: replaces kad.FetchInfo with contact.FetchInfo in Refresh() & removes Discover()
satellite/peer.go: sets up contact service and endpoints
storagenode/console/service.go: replaces nodeID with contact.Local()
storagenode/contact/chore.go: replaces routing table with contact service
storagenode/contact/nodesservice.go: creates empty implementation for ping and request info nodes service & implements RequestInfo method
storagenode/contact/service.go: creates a service to return the local node and update its own capacity
storagenode/monitor/monitor.go: uses contact service in place of routing table
storagenode/operator.go: moves operatorconfig from kad into its own setup
storagenode/peer.go: sets up contact service, chore, pingstats and endpoints
satellite/overlay/config.go: changes NodeSelectionConfig.OnlineWindow default to 4hr to allow for accurate repair selection
Removes kademlia setups in:

cmd/storagenode/main.go
cmd/storj-sim/network.go
internal/testplane/planet.go
internal/testplanet/satellite.go
internal/testplanet/storagenode.go
satellite/peer.go
scripts/test-sim-backwards.sh
scripts/testdata/satellite-config.yaml.lock
storagenode/inspector/inspector.go
storagenode/peer.go
storagenode/storagenodedb/database.go
Why: Replacing Kademlia

Please describe the tests:
• internal/testplanet/planet_test.go:

TestBasic: assert that the storagenode can check in with the satellite without any errors
TestContact: test that all nodes get inserted into both satellites' overlay cache during testplanet setup
• satellite/contact/contact_test.go:

TestFetchInfo: Tests that the FetchInfo method returns the correct info
• storagenode/contact/contact_test.go:

TestNodeInfoUpdated: tests that the contact chore updates the node information
TestRequestInfoEndpoint: tests that the Request info endpoint returns the correct info
Please describe the performance impact: Node discovery should be at least slightly more performant since each node connects directly to each satellite and no longer needs to wait for bootstrapping. It probably won't be faster in real time on start up since each node waits a random amount of time (less than 1 hr) to initialize its first connection (jitter).

Storj V3 Network

Go Report Card Go Doc Coverage Status Alpha

Storj is building a decentralized cloud storage network. Check out our white paper for more info!


Storj is an S3-compatible platform and suite of decentralized applications that allows you to store data in a secure and decentralized manner. Your files are encrypted, broken into little pieces and stored in a global decentralized network of computers. Luckily, we also support allowing you (and only you) to retrieve those files!

Contributing to Storj

All of our code for Storj v3 is open source. Have a code change you think would make Storj better? Please send a pull request along! Make sure to sign our Contributor License Agreement (CLA) first. See our license section for more details.

Have comments or bug reports? Want to propose a PR before hand-crafting it? Jump on to our Rocketchat and join the #dev channel to say hi to the developer community and to talk to the Storj core team.

Want to vote on or suggest new features? Post it on ideas.storj.io.

Issue tracking and roadmap

See the breakdown of what we're building by checking out the following resources:

Install required packages

To get started running Storj locally, download and install the latest release of Go (at least Go 1.12) at golang.org.

You will also need Git. (brew install git, apt-get install git, etc). If you're building on Windows, you also need to install and have gcc setup correctly.

We support Linux, Mac, and Windows operating systems. Other operating systems supported by Go should also be able to run Storj.

Download and compile Storj

Aside about GOPATH: Go 1.11 supports a new feature called Go modules, and Storj has adopted Go module support. If you've used previous Go versions, Go modules no longer require a GOPATH environment variable. Go by default falls back to the old behavior if you check out code inside of the directory referenced by your GOPATH variable, so make sure to use another directory, unset GOPATH entirely, or set GO111MODULE=on before continuing with these instructions.

First, fork our repo and clone your copy of our repository.

git clone git@github.com:<your-username>/storj storj
cd storj

Then, let's install Storj.

go install -v ./cmd/...

Make changes and test

Make the changes you want to see! Once you're done, you can run all of the unit tests:

go test -v ./...

You can also execute only a single test package if you like. For example: go test ./pkg/identity. Add -v for more informations about the executed unit tests.

Push up a pull request

Use Git to push your changes to your fork:

git commit -a -m 'my changes!'
git push origin master

Use Github to open a pull request!

License

The network under construction (this repo) is currently licensed with the AGPLv3 license. Once the network reaches beta phase, we will be licensing all client-side code via the Apache v2 license.

For code released under the AGPLv3, we request that contributors sign our Contributor License Agreement (CLA) so that we can relicense the code under Apache v2, or other licenses in the future.
