Grid - a decentralized version control system

Technology

• golang
• Linux-like file system
• download & upload in HTTP
• compared with git：
  • tech: grid runs as microservices
  • decentralized: any local Grid can become server anytime anywhere
  • easy: more explicit in usage and reminders
  • extensible: can use extensions to see the change between different submit history

Key Features

 server runs grid. Clients also run `grid`. It is a decentralized deployment. Server is nothing different from clients (they all run grid). Since they all run grid, they can be seen as a **grid node** on the internet. So you can actually synchronize things to everywhere(not just Gridle server). Everyone can be either Grid server/ grid client.

the only thing that server is different from client, is server runs Gridle Service but clients don’t

Download

grid -d url
grid download url

#if download before
grid sync

Upload

grid add ./hello.cpp
grid add all #if you are lazy
grid submit "title" "description"
grid sync

imagine that there is a local server for each project they download

after using grid sync, local server will send a request to synchronize to the server

Every single submit has its own ID stored in file system to be identified

History

grid trace <historyID> # in this step, local server will just trace back into the history
grid sync # this step is irrversible. cuz it will affect to cloud server directly

Connect to the Server (other grid nodes)

uses HTTP

grid connect <ip address>
grid test # to test if the sync runs well
grid chat "test" #talk to server

Branch

grid branch create "name"

grid branch delete "name" #this needs 2-step authentication

grid branch "main" #switch to the branch

Conflict (when sync)

• if there are already new changes in the project, but it will not be conflicted with the submit that I am syncing with, it can just choose to merge

$ grid sync
- sync starts!
- Fatal Error: conflict between two submits
- but you can choose to use "grid merge"

$ grid merge
- sync starts!
- [=================] 100%
- Succeeded.

• also can choose to restore files to become the status before it changed

Decentralized Storage of Projects

 Since everything in Grid is decentralized, so does the storage. Grid is integrated a go server. We can see Grid as microservices which communicates with each other by http

Version

 You can actually divide the project into multiple stages (like different versions). Every single version in Grid has its own `release` and `code`

 Version is actually the special version of branch. But we can choose a branch as a specific version. And we can also add release into version like how we did in branch

It is also available to use grid branch to switch our workflow into specific version

$ grid version create
name: Gridle_1.0
version:  1.0.1
description: It is an official version of Gridle

$ grid branch "Gridle_1.0"
$ grid version "Gridle_1.0"

$ grid version update 1.1.2 #updating
$ grid version history #to see the history of updating in version
$ grid history #it is different from the last command. grid history is to see the history of submits in this branch
$ grid submit history 1213 #This is used to see the exact detail of selected submit.

$ grid sync release #it will automatically update "release" folder into the release of this version

Hash Used in Grid

Grid will allocate everything with an identification: `SHA-1` value.

Every file in Grid will be along with a `hash` value, which can be used to see whether the files have been changed by comparing their values.
