Hi Karl, I’m pretty sure everyone’s time is finite, I know mine is! I feel your pain ;-)
My suggestion remains that you pull-request your existing automation code, in whatever state it’s in, into a new directory in the PDLPorters/devops repo. Or, if that’s easier, just copy-paste your code as comment on this issue (https://github.com/PDLPorters/devops/issues/5) opened some time ago by the mighty Zaki. I am hoping this is easily actionable and with minimal friction. Hopefully some people will have the chance to help the creator of PDL with feedback from a quick go at using his new container technology?

That includes things like ‘learning how this CI thing works’. But I have automated this to some extent and hope to do more. It would be nice to have the GitHub CI take care of it, if such a thing is possible? Right now I would like some people to try out the docker container, and report back.

I’d suggest a similar benefit would arise if you released SciPDL more often, but it’s up to you. Having thought more about this, I think the existing PDLPorters/devops repo would be ideal: could you please push on a branch of that, making a new directory within it called something like build-docker, putting your files in there, then make a PR so that people can take a look? Regarding the number of releases of PDL, my approach has been to release it when I thought something valuable was ready. You’ll recall that in the past, just because PDL wasn’t released very often, didn’t mean every single release was perfect. There’s one bit in a release notes from the past proudly noting a release with over 50 fixed tickets. Those fixes were sat on for a considerable period of time, with users unable to benefit from them. We do have literal “continuous integration” (using GitHub Actions) which has all the tests Zaki and I could think of to throw at it, for every single push on any branch: it builds on Ubuntu, CentOS, MacOS, Windows, Cygwin (only for releases, it’s too slow otherwise). It would be easy(ish) to have, probably only for releases, an additional build step that updated a Docker image with SciPDL (and as an added benefit, would show any breakages of that). The CI reports all pushes, and build results, on the IRC channel, which I do recommend sitting on. Having SciPDL be an additional “canary in the coal mine” would be of considerable value. As for which is the last “stable release”, I understand the question, but for the reasons in the last two paragraphs I can’t really accept the premise. If you look at https://metacpan.org/pod/PDL, there’s a not-very-up-to-date “Testers” readout (the numbers are cached, it only shows currently 100 passes), and link. If you follow the link, the current version shown is for 2.057 (the latest), http://matrix.cpantesters.org/?dist=PDL+2.057: it shows 131 passes, 7 unknown (which are build failures, each of which I know the reason for), and no failures (either 100% passes, or 95%, depending on how you count it), across 70 configurations (OS, Perl version). How “stable” were you after, exactly? 😉 Best regards, Ed From: Karl Glazebrook<mailto:karlglazebr...@mac.com> Sent: 17 August 2021 01:56 To: Ed .<mailto:ej...@hotmail.com> Cc: perldl<mailto:pdl-general@lists.sourceforge.net>; Bob Abraham<mailto:abra...@astro.utoronto.ca> Subject: Re: [Pdl-general] SciPDL Docker Hi Ed, It’s a Dockerfile and a build shell script that runs inside it. I went that way as that is what I did for MacOS and docker seemed a nice way of bypassing all the issues with Debian packaging (see other thread) which are frankly doing my head in! I am not sure I feel comfortable sharing my dubious build scripts, could be dangerous, but maybe if it sits within PDL repo. BTW I only make a new SciPDL once or twice a year. It’s kind of my thing to bundle up all the stuff I normally like but others find it useful. So - I see there have been a huge number of new PDL versions this year, which is fantastic (esp. the new complex numbers approach) but I also see things are in a high state of flux. Continuous integration of new changes are not my thing, at least not for SciPDL, what would be the last ’stable version’ to build against do you think? I hope that question makes sense, Karl On 17 Aug 2021, at 1:01 am, Ed . <ej...@hotmail.com<mailto:ej...@hotmail.com>> wrote: Hi Karl, That’s great! Can you share your Dockerfile? Is it on GitHub? I’m thinking it would be great to have it within PDLPorters, maybe in a repo called (very imaginatively) “docker”. Yes, there is in fact now a 2.057 (which restored the DELETEDATA mechanism which it turns out people were using for other than mmap – oops). Please give it a go!

It was on my to-do list for a while, helped me learn more about Docker. So you can run it anywhere you can run Docker with a command like: docker run -it karlglazebrook/scipdl pdl It has pgplot (make sure to set X11 DISPLAY for this) and all the usual stuff etc. I include in my SciPDL ‘kitchen sink' This is still on PDL-2.025, same as MacOS, and is an intel builf, next round to it is to update the PDL versions in SciPDL. (Did I see v56 recently! Jeepers...) best Karl
