Go Dispatch client

 

Overview

Disgo (dispatch + go) is the first client implementation of the Dispatch protocol. Dispatch enables the Zero-Knowledge Analytics of distributed data without comprimising data ownership, privacy, or security.

Come talk with us!

If you have any questions or just want to get to know us better, come say hi in our discord channel (https://Dispatchlabs.io/discord)

Download

With Go installed, enter either of the following commands into your terminal:

go get github.com/dispatchlabs/disgo
or
git clone http://github.com/dispatchlabs/disgo (into your GOPATH)

If you have yet to install Go, visit our tutorial or download straight from the Golang website.

How to run a Disgo node

Disgo is a full dispatch node, and you can run it right out of the box. Simply run the following commands in your terminal:

cd $GOPATH/src/github.com/dispatchlabs/disgo
go get ./...
go run main.go

Using the protocol (Dancing the Disgo 🕺)

• Non-technical users of the protocol can use the network scanner to interact with the protocol.

• Developers "dance the disgo" with our decentralized HTTP API, JavaScript SDK, or Java SDK.

Configuration

The disgo package relies on the configuration loaded by commons

Contributing

We would love your help developing the protocol! It's a big project and we're a small team, so all contributions are encouraged. For more information on how to get a developer environment set up, please check out our dev-tools repo.

Proxy to Delegates

Localhost requests to bookkeeper requiring delegates should be proxied to random delegate.

Concern Regarding Code Quality of Badger

My Posts will be deleted on badger repository. So posting it here, since you guys use badger.

Badger team did changes on May 9th to introduce move keys.
dgraph-io/badger@7af0076

There were many bugs, issues related to same thing which were fixed over months. The last fix was done a week back. The issues ranged from badger being stuck in recursive loop during get to badger not returning data which was inserted.

dgraph-io/badger@d1185f0
dgraph-io/badger@af99e5f
dgraph-io/badger@d055ef4
dgraph-io/badger@3340933
dgraph-io/badger@2e3a32f

@manishrjain How do you plan to address the code quality of badger.

Prompt to create github issue on unhandled error

The idea is if an error has not been handled in code, prompt user to submit the error code and callstack to github. This could be a setting only for alpha/beta releases.
Example:

f, err := os.Open("filename.ext")
if err != nil && reportError() {
    openbrowser("https://github.com/dispatchlabs/disgo/issues/new?title=Missing fil%20to%20invalid%20chain%3A%20%5Bunknown%2C%200%5D&body=%60%60%60%20%0AError%3A%20Launcher%20co")
}

func openbrowser(url string) {
	var err error

	switch runtime.GOOS {
	case "linux":
		err = exec.Command("xdg-open", url).Start()
	case "windows":
		err = exec.Command("rundll32", "url.dll,FileProtocolHandler", url).Start()
	case "darwin":
		err = exec.Command("open", url).Start()
	default:
		err = fmt.Errorf("unsupported platform")
	}
	if err != nil {
		log.Fatal(err)
	}

}
func reportError() bool {
	var response string
	_, err := fmt.Scanln(&response)
	if err != nil {
		log.Fatal(err)
	}
	okayResponses := []string{"y", "Y", "yes", "Yes", "YES"}
	nokayResponses := []string{"n", "N", "no", "No", "NO"}
	if containsString(okayResponses, response) {
		return true
	} else if containsString(nokayResponses, response) {
		return false
	} else {
		fmt.Println("Report error? Type yes or no and then press enter:")
		return reportError()
	}
}
