Hello, during last couple of weeks i was busy migrating migrating VM jobs from Hudson server to more up to date Jenkins server and creating a jobs for running tests on newly built VMs. The new location for built VMs are https://ci.lille.inria.fr/pharo/view/Cog/ I disabled the old jobs on Hudson server (https://pharo-ic.lille.inria.fr/hudson/view/Cog/) and also put a comment where they moved. So, from now all VMs which are built on Jenkins server will be automatically tested. If you go to jenkins page, you could see that each job , like StackVM-Unix has a parallel job named StackVM-Unix Tests , which runs tests after successful build of corresponding VM. The image which is used to run tests is Pharo 1.4. latest build (can be found on same server - https://ci.lille.inria.fr/pharo/view/Pharo%201.4/job/Pharo%201.4/) So, in this way we have a streamlined continuous integration setup, which tests every possible combination(s) of VMs and latest Pharo image, so we can easily track regressions as well as different behavior between platforms (ideally, there should be none ;)) Details about new builds: - it is a merge with VMMaker.oscog-eem.115 which contains an important fix for #become: primitive With this fix, i could say that Cog VMs are much stable! Problems, not yet solved: Windows: - there is no windows jobs yet, because we're still having problems with windows slave (it is inaccessible right now), but once it will work, i will add jobs for windows as well. Mac Cocoa builds: - i migrated the cocoa builds to jenkins server as well, but it is not yet using an updated verison of sources (we have to wait till Esteban will sync sources) - also those VMs cannot run tests because command-line interface for them is severely broken now :( -- Best regards, Igor Stasenko AKA sig.
