Cognitive Systems

Git – what is it?

• Linus Torvalds – inventor of Linux wanted a better source control system – so

he wrote one

• Very popular in the open source community and increasingly in enterprises

• Distributed Version Control System

• Some distinctives

• NOT a server! Just a simple executable

• Stores all of its meta data in one .git directory at the root of your

repository

• Very fast !

Cognitive Systems

Snapshots, Not Differences -> Nearly every operation

local -> FAST!!

From https://git-scm.com/book/en/v2/Getting-Started-Git-Basics

Other VCS store deltas from the

original

Git stores full copies (links, compressed)

Everyone has a full repository

Nearly every operation is local

Full redundancy with all other

repositories


Cognitive Systems

Small & Fast!

Cognitive Systems

High-level flow


Cognitive Systems

Staging area?

• Before the commit, files get "staged"

• Why?

– Commit only one of several changed files

– Commit only a portion of a changed file!

6/18/2017

Cognitive Systems

Hash codes

• All content is check-summed into a SHA-1 hash code

• From then on the file is referred to by that hash code

• Probability of collision is very small ~ # of sand grains on earth

• => the content is tracked so empty directories are not

• Commits are also referred to by a hash code


Cognitive Systems

Branching and Merging

Cognitive Systems

Git hooks

• To install a git hook, just put an executable file in the hooks directory

• The name of the file is the hook

• Example, to install a post-receive hook, do this from the .git/hooks directory

(depending on how you created the repository, the hooks directory may need

to be created)

• Then, populate the file with the commands needed


Cognitive Systems

git hooks (https://git-scm.com/docs/githooks)

• applypatch-msg

• pre-applypatch

• post-applypatch

• pre-commit

• prepare-commit-msg

• commit-msg

• post-commit

• pre-rebase

• post-checkout

• post-merge

• pre-push

• pre-receive

• update

• post-receive

• post-update

• push-to-checkout

• pre-auto-gc

• post-rewrite

• rebase

bit.ly/5733sc1-op1 - 5733SC1 instructions

ssh-keygen contained in 5733SC1 IBM Portable Utilities for i5/OS

*BASE & Option 1

$ ssh-keygen$ ls ~/.sshauthorized_keys id_rsa id_rsa.pub known_hosts

ssh-keygen creates necessary files

Copy/paste id_rsa.pub into GitHub/Bitbucket web interface

$ cat ~/.ssh/id_rsa.pubssh-rsa AAAABxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxpomIpqNexxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxLUMp4zhi4BqGHIl [email protected]

To communicate with repository via SSH, you need to give them

your public SSH key for password-less authentication.

Cognitive Systems

Where can I get Git?

• Can download to your PC

• Can add to your Eclipse

• Can use http://github.org right now and have it hosted in the cloud

• this how a lot of open source is developed

• Or ……

• Install it on your IBM i !

• 5733-OPS option 6

• And then install PTF

• Coming soon

• Follow DeveloperWork Page on 5733OPS

Cognitive Systems

Free form RPG in Orion!


Cognitive Systems

• Aaron Bartell published an article just recently on Orion/RPG

• He told me that he had the most screen caps in any article he has ever

written

• Detailed scenario of how to develop in RPG using Orion

Industry pundits have already published articles

Think through the implications of editing RPG in a

browser

• You can now edit RPG on any device that has a browser

• Windows

• Linux

• Mac

• Tablet

• Phone

• Etc.

• It requires no installation per user


Cognitive Systems

Orion - Language Support

• First class editor support for

• JavaScript

Cognitive Systems

RDi and Git

• Eclipse has a free extension to support

Git called EGit

• Anyone with Eclipse can install it from

the Help->Eclipse Marketplace…

• If you have RDi Java Modernization

Edition – it is an optional component


Cognitive Systems

Think through the implications of Orion + Git

Here's a scenario:

Jesse is travelling. He's at the airport and just has a tablet and his

phone. He receives an urgent call from Edmund that there's a

bug in his code and Sam's pay is incorrect. He logs onto Orion,

fixes the bug, and pushes the change back to Git. Back at the

office, Edmund fetches the change from Git into an i Project in

RDi and recompiles the program. Sam's pay is fixed and the

problem didn't have to wait until Jesse returned from his trip.

Cognitive Systems

Edit RPG to change Sam’s pay – original pay 50000.99


Cognitive Systems

Sam’s pay is edited – now 50000.33

Cognitive Systems

Change is now in the Git repository history


Cognitive Systems

Fetch from Git into RDi
