Re: [Pharo-dev] Roadmap to Pharo 7 Release

by Stephane Ducasse

Hi Peter Now we do not want to rely on Glamour. You should pay attention since it is not maintained and producing memory leaks and we would like to avoid to have to fight to find them. I do not know what are the plans of feenk at this level. This is why we started to redesign Spec.

Re: [Pharo-dev] AnnouncementSubscription and Ephemerons

by Stephane Ducasse

Hi Torsten Thanks for this question. Ephemerons do not work in Pharo sadly and we know it. We cannot then take advantage of them. What you see is in fact a degradation of the situation around the VM. :( We are concerned about this but the path for our future in this domain is unclear. What is clear is that we will reduce the number of Plugin (as pablo did for freetype) and use FFI. But FFI callbacks are not really good. And we need a threaded VM. Now nothing happens on this front. Let us face it there is a bad energy around. After years of discussion our engineers are still struggling and slowed down because of the dispersion of plugin code. In addition, from what I understood there is no development branch :) amazing is not it in 2020! On another scale, since 1 year, I was focusing on making that our institute offers a permanent position to Clement but I failed because the forces against where too strong (politics) and clement should reapply next year. Now to improve his CV, clement is doing a postdoc at VUB and will start working on Truffle (the VM of Oracle) and continue to work part time on Sista. This is not that bad, like that he will gain experience on other systems and in the future we will be in the position to see if there are real alternatives for us. May be writing a new VM on top of other existing infrastructure is the way to go. We will see in the future. To be fully transparent - we will have one phd working on IoT and how to reduce/clean the image and VM size and many other points she will probably work on a fork because I cannot suicide a student (by asking her to understand the messy plugin architecture) and she will need some space to experiment. Now if improvements she will perform take ages to be integrated in the main VM I will ask her not to do it and to focus on her future and science. I imagine that everybody paying attention to people can understand this.

In .git_filters/RevDateURL.smudge there's a line that retrieves the commit date from git: $date = `git log --format=%ad -1`; to get the (short) hash we can simply add: $shorthash = `git log --format=%h -1`; The string substitution can then proceed as for the date. I think it would be worthwhile having both the date and hash in the --version info. I'm happy to add this in and update the --version output if there's general agreement. > As Alistair says, the issue is fixed in the VMMaker.oscog package commit > VMMaker.oscog-eem.2359, which is > > commit 1f0a7da9d4e8dcf4cdfac07014decdadac6937bb > Author: Eliot Miranda <eliot.miranda(a)gmail.com> > Date: Thu Mar 15 18:09:12 2018 -0700 Which unfortunately is 1 commit after the version you have.
