Open Source for IBM i

– New LPO – 5733OPS Open Source for IBM i o New license program option o Designed for Open Source offerings on IBM i

5733-OPS: a bit unconventional?

• 5733-OPS has 15 options available NOW!

• The options themselves are placeholders

• Function will be delivered via PTF

• We now have a PTF group for each IBM i release!!

SF99123 (7.1) SF99223 (7.2) SF99225 (7.3)

7 9/22/2016

Things we deliver with every new language/version

• ILE Object Toolkit • Toolkit for each environment to easily allow connections to ILE objects and information – Built on XMLService

• SQL Connector • Easy integrated (from the open source language) way to transfer data to and from DB2 for i leveraging SQL

Node.JS – 5733OPS Option 1

• What’s Node.JS? – Simply put, Node.js is server-side JavaScript – Based on Google Chrome V8 Engine.

• Why Node.JS? – Great for web development! o JavaScript is already widely used on the client side of web development o Can now do both – High Performance o Node.js is designed to maximize throughput and efficiency. – Increasing popularity: o More than 70,000 third-party extensions are available on www.npmjs.org now. © 2016 IBM Corporation

Python 3 – 5733OPS Option 2

• What’s Python? – A powerful general-purpose language – Interpreted

• Why Python? – Easy to use o Language is designed to be a "fun" language o Can be considered the 'CL language for the modern programmer' o Easy for IBM i programmers to learn

– Very, very popular o Over 85,000 third-party extensions are available on http://pypi.org

Python success stories!

• https://www.python.org/about/success/

• 41+ real-life success stories across multiple domains

10 9/22/2016

Origin of the "Python" name?

"Now, it's quite simple to defend yourself against a man armed with a banana. First of all you force him to drop the banana; then, second, you eat the banana, thus disarming him. You have now rendered him helpless."

"This parrot is no more! He has ceased to be!"

"I’m sorry to have kept you waiting, but I’m afraid my walk has become rather sillier recently."

"I don't like Spam©!"

"That rabbit's dynamite!"

IBM i chroot (change '/' location), 5733OPS Option 3

Ranger chroot /QOpenSys/ranger '/' is … /usr/bin/bsh /QOpenSys/ranger/(*) Bobby chroot /QOpenSys/bobby '/' is … /usr/bin/bsh /QOpenSys/bobby/(*) Lefty chroot /QOpenSys/lefty /usr/bin/bsh '/' is … /QOpenSys/lefty/(*)

Wild Bill '/' is ... chroot /QOpenSys/wildbill /QOpenSys/wildbill/(*) /usr/bin/bsh admin No chroot, '/' is … /(*) No problem, but you are not going to mess up my system, so chroot you.

11 9/22/2016

IBM i compilation environment, 5733OPS Option 3

• Scripts to set up gcc and other popular build tools

• PASE has XLC, not free, and not very compatible for Open Source

• Not only can you get a real build environment, you can do so inside a "chroot" and have isolated, sandboxed versions of the build environment!

5733 OPS – Lots delivered in June 2016!

• Option 1 – Node.JS 2.x • Option 2 - Python 3 Enhanced • Option 3 – GCC / chroot

12 9/22/2016

June 2016 enhancements to option 2 – Python 3.4

• Python v3.4 was initially delivered June 2015 • Key updates in June – Wheel (updated packaging mechanism) – Package add-ons as wheels – Rebuild with gcc technology to allow easier integration with community – Better support for Django, a powerful web framework for Python o Django requires a database o Only solution previously was to use Zend DBi (out of process), PyMySQL, and a spec of MySQL that doesn't meet Django requirements o Now we have a solution that goes straight to DB2

5733 OPS – Lots delivered in June 2016!

• Option 1 – Node.JS 2.x • Option 2 - Python 3.4 • Option 3 – GCC / chroot • Option 4 – Python 2.7 • Option 5 – Node.JS 4.x • Option 6 – Git New • Option 7 – Tools • Option 8 – Orion • Option 9 – cloud-init

13 9/22/2016

Option 4 – Python 2.7

• Python v2.7 (option 4) to be delivered 1H2015 – initial delivery, built with GCC – Wheel – toolkit and database connector

– Why? o Python 2 and Python 3 are not fully compatible o Python 3 not fully accepted by the Python community o Many applications still built on Python 2

Option 5 – Node v4

• Previously shipped Node.js v0.x (option 1)

• Node v4 move is important – New Javascript engine (much better performance) – New Javascript language features (classes, among other things)

14 9/22/2016

Option 6- Git

• Open Source distributed version control system • Source control for virtually any language • Powerful and flexible • Can have hooks to perform custom actions when new code is integrated • Already in use in the IBM i community

Option 7 - Tools • Some of the packages downloaded via GCC tool kit are core to the success of Open Source development for IBM i

• In June, we shipped key packages – bash – zip – unzip

• Others that are being considered… – shellinabox – gzip – bz2 – tar – perl

15 9/22/2016

shellinabox – future?

• Candidate for OPS option 7 • Access an SSH terminal through virtually any web browser • No browser plugins required, just basic CSS and JavaScript support

Option 8 – Eclipse Orion

• Provides a web enabled editor interface • Rich git integration • BlueMix integration • Targeting Node, Python and Modern RPG developers • Not meant to compete with RDi, more complementary – Hope to attract and supplant more green screen SEU users • Contains base open source Orion with a RPG syntax highlighter supporting Fully Free Form RPG only (along with an SQL subset) • Integration story with RDi will be based on Git

16 9/22/2016

Option 9 – Cloud-init for IBM i

• Cloud-init is a script that enables virtual machine activation and initialization • Additive to the PowerVC/PowerVM offering

Welcome to the Waitless World

Which language to choose?

17 9/22/2016

Ruby

• The language: – Everything (yes, everything) is an object – Blocks (closures) integral to the language – Easy to create domain-specific languages • Pros: – Powerful language – Very expressive, “Beautiful” – Rails very popular web development • Cons: – Not as popular as Python outside of web – Language warts not tolerated, will break things to make them better → you must keep up – Paradigm shift from traditional RPG/C/Java

Python

• The language – Indentation determines block level (love it or hate it) – Easy to integrate with C/C++ code → many packages created • Pros – Easy to pick up for RPG/C/Java developers – “Conservative”: slow change, compatibility a goal, straight-forward syntax – Many packages available – Has an IBM i toolkit with direct-call capability (iLibCall) – Taught in many colleges • Cons – Not as popular for web (but capable: Django, Bottle) – Python 2 vs Python 3 incompatibilities (improving)

18 9/22/2016

Node.JS (JavaScript)

• The language – Curly-brace style language (C/C++/Java) – Prototype-based, not Class-based (no inheritance) – Highly asynchronous, event-driven • Pros – Use same language for frontend and backend – Lots of buzz around Node.js now – Node.js uses JIT, not interpreted (good performance) • Cons – Syntax is “awful” (projects to compile to JS: CoffeeScript, TypeScript, …) – Asynchronous more difficult than synchronous, requires different mindset, “Callback hell” (Promises improves things) – Event-driven IO not unique to Node, see EventMachine (Ruby), Twisted (Python), ... – Not as popular outside of web

PHP

• The language – Often embedded into HTML • Pros – The "granddaddy" of open source languages on i – The most IBM i shops running PHP, the most community – Comes with a robust Development Environment – Can get a support contract from Zend (1 year free) • Cons – Currently not as quickly-moving – Typically only used for serving up web pages

19 9/22/2016

The right answer?

• It depends….

• Things to consider: – popularity/momentum – packages available – What are you using it for? (typically wouldn't use Node.JS or PHP for general purpose scripting, for instance) – tooling – skills

The wrong answer?

• There is no wrong answer!!

• likely not your last language decision…

Open source to the rescue!! CRTFRMSTMF, written in RPG https://bitbucket.org/BrianGarland/crtfrmstmf

(by the way, also wired into the Relic package manager)

OSSILE

• Created with partnership to host more ILE open source code • Populated today with UDTF's from Christian Jørgensen – Machine info – Cartridge info – Image catalog details

• Will absort CRTFRMSTMF

• Code queued up with help from the Large User Group (LUG), more specifically: Michael P. Scott

• Key points: – Will compile into a library called "OSSILE" – Will be integrated with the Relic Package manager

29 9/22/2016

OSSILE

• Coming…. – User-defined table functions (UDTF's). Nature of services includes: o Process Control Locks o Interrogate all kinds of IBM i object types o Activation group garbage collector o Table Spaces o XML Services o Block Fetching – Other handy utilities o CLRPFMSBX – Clear a physical file even if it has triggers or referential integrity constraints. o ENDOBJLCK – An interactive command that collects all the jobs that are holding locks on an object and ends them elegantly o GENSRVLYR – A template-based code generator that builds a service program for a table, providing all the basic CRUDE operations plus Table Space support
