Stef, Apologies if I am exploiting something you meant to send privately, but "draft of a chapter" on FFI?????!!!!!! :) :) :) I'm no expert, but I certainly like to see what is being written. It is difficult to imagine how I could fail to learn something from it.

Re: [Pharo-project] Windows disappear in saved image on startup

by Larry Kellogg

Hello Stef, Thanks for the reply. Sorry for the delay in responding. I have been working on a local copy of Pharo. I will have to get back to the Amazon instance at some point in the near future. It would be great if I didn't have to start from scratch. >> Did you publish your packages? No, I did not publish my packages. They're not for public consumption, at least not in their current state.

I am also puzzled by this behavior. Perhaps I will post a short video that shows how all of the windows coming up, with the state saved correctly, and then, a second later, everything disappearing. It is a frustrating bug.

If you just need to retrieve packages from squeaksource, you might use the chilean mirror http://dsal.cl/squeaksource/ On Wed, Nov 30, 2011 at 10:22 AM, Fabrizio Perin <fabrizio.perin(a)gmail.com>wrote: > It is alive but slow.

Thank you! > > The problem is of course less one's own packages, but the big packages we > depend on, Seaside, Glorp, XMLSupport, â¦ > yes :( But... what I do for my images ( http://marianopeck.wordpress.com/2011/11/19/loading-projects-and-building-y…) is to use the same package-cache for ALL images. Since I am building all the time, it is likely all needed mcz will be in such package-cache. If you use the last version of those packages (seaside, glorp, etc), then it will load the last one found in package-cache. If you use a fixed version, if it is found, not problem. If it is not found -> error. So...in my builder, I can do GeneralImageBuilder buildOffline: true. THen: loadPackages: packagesOrGroups | version repo | self generalPreLoad. version := (ConfigurationOfMariano project version: #bleedingEdge). self class buildOffline ifTrue: [ repo := MCDirectoryRepository new. repo directory: self sharedPackageCacheDirectory. version repositoryOverrides: (OrderedCollection with: repo). ]. version load: packagesOrGroups. Conclusion: 90% of the times, I am able to recreate an image from my own package-cache. Cheers -- Mariano http://marianopeck.wordpress.com
