[Pharo-project] 'file:spaceTally.st' asUrl retrieveContents should work?

by Mariano Martinez Peck

Hi...I was running a pharo headless in Mac OS running something like this: ./Pharo/VM/Squeak\ 4.2.5beta1U.app/Contents/MacOS/Squeak\ VM\ Opt -headless Pharo/imagenes/Pharo-1.1-11411dev10.07.1/Pharo-1.1-11411dev10.07.1.image spaceTally.st And I come to the problem that there is an error while trying to process spaceTally.st. This file is a text file that just contains "SpaceTally new printSpaceAnalysis" Now....to conclude, the problem is that according to the wonderful and nice CodeLoader (I really hate this class...I promise I will do something with it) this: 'file:spaceTally.st' asUrl retrieveContents should answer me the contents ("SpaceTally new printSpaceAnalysis") ...but instead nil is returned. The file exist. Is this wrong? is it expected? how can I fix it ? Thanks!! Mariano

Is PostgresV3 production ready, last time I checked it seemed like it was not ready vs the older PostgresV2. I must have missed its progress (no pun intended). Is there some writeup about this package somewhere ? Thx, Sven

These apps use Squeak trunk images (updated regularly, but manually) with Seaside 3.0 (some with Comet), WebClient, SqueakSSL, OSProcess, PostgresV3. These are not mission critical apps (a few minutes downtime is acceptable), but they are running 24/7. Before WebClient+SqueakSSL we used Curl, but the plugin was leaking memory, so the images had to be restarted regularly. Curl was also significantly slower.

I added links to the latest unstable to the download page. I change the links to 1.1 to point to stable-core and stable, too. So they will be correct when we do a 1.0.1 http://www.pharo-project.org/pharo-download Marcus -- Marcus Denker -- http://www.marcusdenker.de INRIA Lille -- Nord Europe. Team RMoD.

[Pharo-project] Making the compilation process more testeable

by NicolÃ¡s Paez

Hi, I am working on a project experimenting with the compiler-related stuff. I had to introduce some small modifications to some classes used in the compilation process in order to complete my experiment. I wrote some test to be sure I don't any add buggy code. While doing this I noticed that if you try to compile "invalid" code programmatically instead of getting an exception you just get some messages on the Transcript. After debugging for a while, I discovered that one of the classes responsible of this behavior is *UndeclaredVariableWarning** *(defaultAction method). I have just reported an issue for this: http://code.google.com/p/pharo/issues/detail?id=2852 Regards. Saludos! Nico. blog: http://nicopaez.wordpress.com
