The problem of the instability of SS is that using files as a back end when you put hundred thousands of files in on folder does not scale. Guess how many files are in the seaside repository :) and the pharo?

Re: [Pharo-project] Addition to "About Pharo" dialog

by GermÃ¡n Arduino

I think that having problems in software is a common reality, unfortunately. May be Squeaksource and it's servers (I don't know) are having a lot in these days, but the point I would mention is that is needed to think in "availability" more than in have 0 problems. The problems will exist, sooner or later, with SmalltalkHub or Squeaksource3, the challenge is, in my point of view, to have availability (some ways of reaction) in front of different failures. May be Squeaksource3 (based in Gemstone) is already covering this topic, and surely also SmalltalkHub could do it, but this is the key in my opinion, not have a single point of failure. Just my 2 cents. 2011/8/27 StÃ©phane Ducasse <stephane.ducasse(a)inria.fr>: > > On Aug 26, 2011, at 7:14 PM, Alexander LazareviÄ wrote: > >> Hi Stef! >> >> 2011/8/26 StÃ©phane Ducasse <stephane.ducasse(a)inria.fr> >> In Squeak alexander lazaverich did a SystemReporter.

Re: [Pharo-project] squeaksource is down

by Oscar E A Callau

Hi, I understand you. It is actually not a problem of squeakSource. But for me, it is really a pain in the a** , because I need to download some project that seems to be only in the squeaksource (at least the version that I want). Isn't there a mirror? If not, we can start to think about it. Cheers. Oscar On 27 Aug 2011, at 05:08, Fabrizio Perin wrote: > Hi, > sorry but this time it is not fault of squeaksource.

Re: [Pharo-project] #name

by Jimmie Houchin

I want to state that I naively and accidentally experienced this. I was using #name as a temp variable in a class method, representing the name of a file. I did not notice that my anticipated temp variable was not a temporary variable but rather a variable that once assigned to change the name of my class. I corrupted several images with this method before tracking down what was the cause of my corruption. I was not attempting to use #name as a class or instance variable. So this discussion did not come to memory. I just wanted to add my experience to the archives of this list so that others may understand the dangers involved and possibly help with discovery of their problem should they make the same mistake.

No, because 'DeNigrisSetup-Platform.pharo' is not a package name, but a package name and a branch name. Earlier versions of Gofer also supported prefix matches, but it was removed it early on because it is very fragile. If you really needed it, you could easily add your own GoferReference subclass.

A new GemStone-hosted SS sounds good, but my own curiousity is burning. I probably missed the discussion about whether we ever attempted to debug and fix this situation by means other than complete replacement. I'm very curious to know, what is the nature of the scalability/crashing problem with SS that this community has been (uncharacteristically) unable to solve?
