[Pharo-project] [ANN] SqueakNOS update released!

by Javier PimÃ¡s

For all those who may be intrested, we are glad to announce that we have just uploaded an updated version of SqueakNOS to our site. You can find the updated download links here <http://squeaknos.blogspot.com/p/download.html>. This release adds the following items to the previous version: (99.9% modeled with objects) - Improved support for ATA devices access - Implementation of a model of files and directories - Implementation of FAT32 filesystem - Support for reading sources from the hard disk - Support for X86 paging setup and handling of page faults - Implementation of a model of free and used memory - Implementation of image snapshotting (based on the paging mechanism) - Based on Pharo, but also supporting Squeak and Cuis - Added some primitives for communicating between VM and image - Support for Alien and FFI - Added basic support for writing to serial via VM so that it's possiblo to out debug info to the outside world. - Added pretty basic ATA benchmarks - Added some scripts to automatize work done from the outside world - Many code cleanups Future directions are: - Support for Cog VM - Investigate replacing SqueakNOS plugin with NativeBoost so that we do more on the image - Offloading memory pages to disk - More tests - Benchmarks For the brave ones, remember that you can always generate a SqueakNOS image by using the ConfigurationOfSqueakNOS (which is a bit outdated now), or by manually loading the packages from monticello. Also to generate a SqueakNOS VM download its code from GIT (hosted on sourceforge.net) Don't forget to visit squeaknos.blogspot.com for news and instructions. We hope to be able to write more soon. Many thank's t all the people who made it possible to understand the code and to develop all this. SqueakNOS' Team -- Javier PimÃ¡s Ciudad de Buenos Aires

Re: [Pharo-project] [Pharo-users] Do you have a tool that works on Pharo ?

by Dale Henrichs

Mariano, You are correct, you need 1.0-beta.28 or later for symbolic versons to work. I intend to keep Metacello running on all versions of Pharo and Squeak4.x and GemStone. For example, I load Seaside30 into a Pharo1.0 image every time a new Seaside30 version is released. ... If anyone finds a problem with Metacello on any platform or version report it (send mail to the Metacello Group or submit an issue: http://code.google.com/p/metacello/issues/entry) and I will fix the bug. Which just leaves use with "upgrade magic" and the user will have to do that ... at this point, I don't think it is a good idea to have Metacello "phone home" for automatic upgrading, so it takes a manual operation to upgrade: ConfigurationOfMetacello project updateProject. ConfigurationOfMetacello load. I am continuously fixing bugs in Metacello and I recommend that users periodically update to pick up the latest bug fixes, so it is probably worth mentioning at the beginning of the section that folks should upgrade to the latest Metacello version whether or not they plan to load additional tools. You can check for new versions on this page: http://code.google.com/p/metacello/wiki/10betaVersionDescriptions and you can tell what version you are currently running by printing this expression: ConfigurationOfMetacello project currentVersion.

Another problem I found is that symbolic versions where integrated AFTER Pharo 1.0 and 1.1 were released. So, if you document that people should use #stable instead....then they will raise an error in Pharo 1.0 or 1.1. A possible solution is to change your conf so that it makes sure to update Metacello. BUt this is complicated because you cannot be sure that metacello will always work there. IF metacello 28 (where symbolics are) works perfect in 1.0 and 1.1, AND IF there is a magic way to tell metacello to update only to .28 then we can add such code in #stable or some place in the conf.. but I am not sure. I prefer to document clearly. cheers mariano Dale On Mar 21, 2011, at 4:00 AM, Alexandre Bergel wrote: Shouldn't it be: (Smalltalk at: #ConfigurationOfOCompletion) project version: 'stable' load.

Someone that knows how that he has to browse MetacelloRepository, probably knows how to install the software, what it is, etc. With this page (after, moved to the pharo website) we want to targe business and new comers. Imagine someone arriving to Pharo and asking himseld "mmmmm does Pharo have XXX that I have in YYY language? ". So the idea is to show all the available tools.
