Zigi gseuk - open source conference 2019 presentation v1.0
- 1. ZIGI - Developing Open Source Software for The Mainframe Henri Kuiper zdevops.com November 2019 Session MO Place your custom session QR code here. Please remove the border and text beforehand.
- 10. Let's be honest, who remembers these?? • Packaging your code with a rubber band • Tagging it with a sharpie • Pray to the punch-card gods that Steve from operating would not drop them
- 11. Collaboration: how do we do it? The Mainframe Peeps • Shared datasets? • TSO XMIT? • CBTTAPE? • ISPW / Endevor / Topaz / SCM ? • Anything else? • Does it scale 'outside of the Enterprise'? The Rest of the World™
- 18. Rough Timeline 2018 2019 Q4 Q1 2021 Q2 Q3 Presented on GIT and showcased 'zigi' ar GSEUK 05/11/209 Email from Lionel 02/04/2019 1st XMIT of panel flow 01/06/2019Approval for open source 26/04/2019 ISPF 'kinda' working 17/06/2019 zigiception 03/09/2019 zigi v1r0 released 07/11/2019
- 19. Challenges • Timezones • How to collaborate on z/OS development • (the main reason I started zigi in the first place lol) • z/OS 1.10 vs. z/OS 2.1+ • Skill Gaps • Technical Challenges
- 21. Collaborate development without zigi • Sending each other XMIT files • Keeping umpteen versions of 'his stuff' and 'my stuff' • Diffs via SuperC (we all love 3.12 don't we?) • Merges via 'cc, cc, cut, paste, a' rituals (that sometimes broke) • Timezone difference turned out to be a big helper • So did shifting priorities • Still a big P.I.T.A. in hindsight (especially now zigi is alive)
- 22. Operating System Differences • I was not running the latest and greates ZPDT at the start • Latest git (by rocketsotware) did not work on my 1.11 • Features zigi despreately needed were only in the newer version of git • Managing two 'branches' (manually) one for 1.11 and one for 2.1+ • Operating System setup differences. (PREFIX/NOPREFIX, available HLQ's, ALLOC issues
- 23. Skill Gaps • Lionel is an ISPF Guru but lacked GIT usage experience • I'm somewhat of a seasoned GIT user, yet a noob in ISPF Panel development • Luckily we had a common ground: mainframes, the love for open source and collaboration and an almost nerdy desire for perfection J • We both learned a lot from each other and it was a ton of fun!
- 24. Technical "Challenges" • Staying true to the 'default' ISPF way of working whilst using the way of git. • Moving datasets between MVS (z/OS) and OMVS (USS) • SSH Keys.. • LMMSTATS • One word: bpxwunix.... Aaaargh! • Git on USS best(?) runs in bash not sh • Detecting 'system'-valid DATASETNAMES (on every system)
- 27. bpxwunix(cmd,,stdin.,so.,se.) • Never use a logon shell J • But then there is no $HOME L • You notice /etc/profile and ~/.profile are not sourced... • And sometimes, they print stuff...
- 28. Getting files from USS to MVS and vice versa • The 'Scottish'-commands: • OPUT & OGET are 'from the MVS point of view' • OGET: OMVS/USS -> MVS • OPUT: MVS -> OMVS/USS • The 'normal' cp-command: • Consider the –M and –U options • We all know cp "//'SOME.DATASET(MEMBER)'"/path/to/target ? • Make sure to escape the $-sign!
- 29. Some statistics... • Lines of Code : •4295 • Number of commits: •251 • Number of issues: •128 (17 open) • Amount of fun: •∞
- 31. Live Demo and Release :) • Installing zigi • Creating our first repository • Pushing to GitHub • Cloning from GitHub
