[Pharo-project] Releasing 1.3: TODOs

by Marcus Denker

TODOs to get 1.3 released: 1) store a 1.3Core on gforge build with an old vm. Double check it works with old VM. It is likely that, again, I did not think about this for some of the images on gforge... it might mean that we need to re-generate images and re-build the Full image based on that. I should again stress that this situation is sucking the live out of people (at least me) and we need to *simplify* our story *considerably*. This is *not* sustainable like this. 2) store a 1.3 on gforge (take form Hudson). double check with old vm 3) update the one-click with reasonable Vms. Which ones? I am confused wrt to VMs, so I need help here. 4) update the website. - especially regarding VMs For 1.4, we should *really* *really* make sure that we auto-generate the *final* *unchanged* release artefact... and *one* *defined* family of VMs, with the one-click (and just one one-click, not two) build from the latest VM.

[Pharo-project] Cog VMMaker.oscog-eem.114/r2485

by Eliot Miranda

Hi All, please find new VMs in http://www.mirandabanda.org/files/Cog/VM/VM.r2485/. These fix a couple of long-standing bugs. One is a rare crash in GC on copying a compiled method, caused by the VM not making sure that a copy of a method that has been compiled to machine code is an independent copy. The other is a potential bug in GC with become where a become causes some machine code methods to gain references to young objects but the VM forgets to include these methods in the young referrers (those machine code methods that refer to young objects). -- best, Eliot

[Pharo-project] small fix to help newbies

by P.

Hi folks, I'm sending this email to both Squeak-dev and Pharo-project as you can see. This is to suggest a fix. I typed this on a workspace: closure := [:x | Transcript show: x]. closure value: "hey". And when I "did it", the VM had me looking at this: closure := [:x | Transcript show: x]. closure value: "hey". Argument expected -> Which is cryptic at best for a newbie. I visited #squeak(a)irc.freenode.net and asked there. Ken Causey helped me out and even he missed the difference between "" and '' for a second. I believe it would be beneficial to newbies to have this enhanced somehow, to point out the fact that strings aren't double-quoted. Thanks, Peter

Re: [Pharo-project] Web app security

by Diogenes Moreira

+1. but in this way, you will be protect the "external" enviroment.(filesystem, process,etc) you have the internal enviroment risks.. in the image.. I think, the best way, is generate some like a sandbox.. a filesystem segment and image segment with the "Inmutables Object".. where the user can't change the instances/objects and others where the user playing.
