Fwd: Pharo

I am forwarding this dialog I held with Stuart for reference in the list. ---------- Forwarded message ---------- From: Ramiro Diaz Trepat <ramiro(a)diaztrepat.name> Date: Sat, Jul 25, 2009 at 7:31 PM Subject: Re: Pharo To: Stuart Herring <st-lists(a)stuartherring.com> Hi Stuart,That was a great idea, I did not know you could just drag & drop .sar files to the image. In spite of that, the server is not working in Pharo. When I run: serverConsole := MagmaServerConsole new open: dbPath; processOn: 51001. It hangs on MagmaSession>>submit:to: It may have to do with the new Closures in Pharo, I don't know. Cheers, and thanks for your help. r.

Fwd: Problems loading Ma client-server
by Mauro Esposito 26 Jul '09

26 Jul '09

Hello everybody, I am having problems trying to install *Ma client server package* and it's dependences. I have tried with Squeak 3.8 and 3.10 but it shows an exception and it doesn't continue loading any more. I think it will be useful for what i want to do. I want to send an object to a remote socket. I am working with Squeak 3.8 because it has classes (StreamingMP3Sound and others) that are not included in latest images like 3.10. I want to know if there's another way to load it (I have also tried to load it from the PackageLoader but it didn't work), like an ".st" file or if some image that already has it installed. I have to say that I don't speak English so i tried to do my best. Thank You!

Magma: r42Gamma5
by Chris Muller 12 Jul '09

12 Jul '09

I have just posted yet another gamma release of Magma 1.0, release 42, to both MagmaTester project of SqueakSource and also SqueakMap. It contains several great fixes and enhancements: - Renewed WriteBarrier support! Please feel free to enable the WriteBarrier flag for 30%-300% overall client performance improvement (depending on many factors). The entire test suite passes with WriteBarrier on and I am using it in one of my own applications. If anyone encounters any WriteBarrier problems, I will support them. - Some significant additional performance improvements regardless of whether WriteBarrier is used. - Fix for removing indexes from an existing MagmaCollection. - Fix for using index keySizes > 1023 bits! - HA fixes and more robust HA deployment. - Several fixes for use of ForwardingProxys, final step to achieving massive scale. - Better error-handling. - Fix for compile-error that occurs in later Squeak images. - Fix for interrogating which session has a MagmaCollection "locked" (e.g., due to rebuilding an index). Wow, I didn't think so many things would be improved from gamma4, *thanks* folks for all of the problem reports! The change in the RepositoryDefinition regarding the ForwardingProxy's required a minor "upgrade" to the RepositoryDefinition of legacy repositories. This happens automatically (but with a Warning first). After installing this latest code, when the repository is re-opened, a Warning will be signaled to upgrade from 10 to 11. Press Proceed to do the upgrade. Hopefully you will not find any further problems and this will be the last gamma for release 42! - Chris

Chris After much cussing I loaded R41.2 and it works fine in seaside 2.8.4. I think this is significant as increasingly only web apps are viable. There is the minor load error. I appreciate your work.
