thanks Now do you have a case where the categories get lost (because they should be saved in the change file) And we may broke something. Which version are you using?

Re: [Pharo-project] Crash dump report

by StÃ©phane Ducasse

thanks a lot for sharing that with us. Did you try with the VM with the new semaphores? and without the new semaphores handling? In the two cases the primitives used looks different. Could you also provide a size of the image? If the crash reproducible?

It seems that I *was* using Spec after all :-) Only I didn't know it... At least I think so, since I defined the UI programmatically... I used information from here: http://book.pharo-project.org/book/LanguageAndLibraries/GUI/PolymorphTutori… and here: http://www.pharocasts.com/2011/02/pharo-gui-with-polymorph.html And if I understand correctly Spec and Polymorph don't compare, because Spec "uses" Polymorph (right?). 2012/11/12 Damien Cassou <damien.cassou(a)gmail.com>: > On Mon, Nov 12, 2012 at 8:06 PM, Sebastian Nozzi <sebnozzi(a)gmail.com> wrote: >> P.S. 2 -- I was amazed at how easy it was to code the UI!

Re: [Pharo-project] [Pharo-users] CategorySaver

by Fernando Olivero

Sebastian, thanks for sharing your code and thoughts. Maybe what Mariano was implying is that you already have the data for the backup in the changes, and having yet another mechanism for that adds complexity to the system. I think is a good idea, but too focused on the categories you choose up front..and not on those actual changes you perform on the system. Which is why the recovering from the changes file is better. Dont worry, the image crashes every now and then to all of us! fortunately since Pharo1.0, less and less every day... Regarding the UI, you should check out Spec, by Benjamin and Stef. It's easier to create morphs programmatically than with the raw Polymorph. And also check out Glamour, the ones used in Moose.

You probably never need any backup... until you do :-).

First, thanks for sharing this with us. Now, I would really like to understand if this is a real need of a new tool or a demonstration that the current tools need some improvements. As you may know, we always have the .changes and therefore we can tools to recover lost data from there. We have the change sorter, the "recover lost code", etc. We are even able to load the .changes in another image. So...my question is, what is the actual problem/limitations with those which are "solved" with this new tool?? or in other words, why do we need this new tool? should we improve the already existing tools instead?

hey sounds nice :) does it save version after version right?
