Re: [Pharo-users] Contrib CI > Cannot build

The priority of the consortium is to pay the salary of clement and esteban and so far we are there yet. For the rest is a bonus. We get the inria Jenkins for free and yes SmalltalkHub is still beta but this is not because I tried to push nicolas petton to deliver and also stay in Smalltalk. So as soon as iceberg is working for me, I will move all my projects to github and I will encourage everybody to do the same.

Yes we check with christophe and we got some linux salves totally super strange. My book was systematically breaking on it. We reported it to the service. I know that Inria is hiring a new guy to improve the service.

Re: [Pharo-users] Dictionary whose values are dictionaries

Thanks. This is nice. I'm thinking that the at:at: could be a nice addition to our Dictionary class.

STH having trouble, VM snapping, CI going tits up randomly. We need to get our act together here. Because it makes it hard to showcase our stuff to third parties. Is that why we get Git, Travis and AppVeyor going strong these days? Maybe some consortium money could be used to have some hosted Jenkins service with proper SLA.

Contrib CI > Cannot build

by phil＠highoctane.be

I am trying to get JiraTalk on the contrib CI but it keeps failing. Check: https://ci.inria.fr/pharo-contribution/job/JiraTalk/16/PHARO=50,VERSION=dev… Clues? I am able to load the configuration and do all of this on my local Jenkins, so I am puzzled (albeit I do not have slaves etc). I tried to put linux or ubuntu in the [Advanced] "limit where the job can run" but to no avail. Help. Phil

Nice pick up. Now in Settings (in a fresh 60473 image), filtering on "halo" shows only: * Cycle both directions * Encloses fullbounds * Exhibits bounds so the comment seems irrelevant and #halosEnabled & #halosEnabled: each have one implementor class-side of Morph with one sender from MorphTest each, and one sender from Morph>>addHalo: and "Morph halosEnabled" ==> true, so the statement seems unnecessary.

Its an evolutionary book originally from Squeak. It could well be that some parts of the book have been cleaned better than others to match Image changes. Thanks for reporting, and even better if you can correct it. cheers -ben
