Re: [Magma] Error creating a Repository

My apologies in advance if I've goofed somehow. I am at work now, so I can't research the issue, but please make sure you try it in a fresh 3.2final image because that is what I verified all the test cases in before I posted it. I will look into it tonight when I get home. - Chris __________________________________________________ Do You Yahoo!? Yahoo! Health - Feel better, live better http://health.yahoo.com

> I break with �undefineAllVirtualInstVars� that MagmaCollection class don�t recongnize in method �initialize�... Folks, the posted version will successfully load into a fresh 3.2 final image and all of the test cases run through. That's the quality-check I did for this first release. Are you using 3.2 final?

UML tool
by Jason Dufair 01 Aug '02

01 Aug '02

Does anyone recommend a (free) UML tool? I want to document STOMP and I've started playing with ArgoUML, a tool I looked into a few years ago. Seems pretty nice, but a) is a bit more than I need, it seems and b) seems to be very java-oriented. Thanks. -- Jason Dufair - jase(a)dufair.org http://www.dufair.org/ "Nobody gets a lifetime rehearsal As specks of dust, we're universal" -- Indigo Girls

[ENH] Point>>sign
by ducasse＠iam.unibe.ch 01 Aug '02

01 Aug '02

from preamble: "Change Set: Point>>sign Date: 1 August 2002 Author: stephane ducasse define the method sign returning a point representing the sign of the receiver constituents. Certain methods often accept aPoint or a number but sign was not defined on Point reducing the polymorphism between number and points. "!

(Assuming as Tim mentioned that it could be moved to an official-looking 'squeakfoundation' site of some sort.) The AllProjects page is better than nothing, but this would be a lot better. I have actually already talked with Cees about moving it (when it's ready) to SqF. Thanks for the support. Right now it hung on me... Hrmph. :-) regards, Göran

Has anyone bothered to check out SqueakMap?
by Göran Hultgren 01 Aug '02

01 Aug '02

Hi guys! I don't want to NAG, but have anybody at least looked at SqueakMap running in part on: http://marvin.bluefish.se:8000/sm Do note that SqueakMap is NOT only for the new modules system - far from it in fact. Let me reiterate in short: - A master server will run SqueakMap on squeakfoundation.org (or similar) - It will have the webUI you can see above (but prettier and with more functions) - You will be able to search (using Scott's engine), browse (similar to Yahoo or GNOME software map), register and update Squeak packages and Module repositories. - A Squeak package is simply a piece of published Squeak software. It does not need to be packaged as a 3.3alpha Module. - A module repository is more or less a "mount point" in the global virtual module namespace that the new modules system introduces. - You will also be able to run your own "local" slave map in your image and synchronize it really efficiently using simple HTTP/gzip (straight through firewalls and a modem will do) with the master. - The slave map (and the master) keeps it's state in one simple logfile using chunkformat. Simple, efficient and since the map opens/closes on each operation it is always written to disk. - You will have a nice MVC/Morphic browser to do all these functions inside Squeak. - You will be able to install any module (as in the new modules system) in the world by just knowing it's module path since the slave map will be able to figure out which repository the module resides in. Well, it will not bring World Peace but it sure will be an important piece of the Squeak community so PLEASE... Take a look, read the help pages and give me some FEEDBACK. regards, Göran Göran Hultgren, goran.hultgren(a)bluefish.se GSM: +46 70 3933950, http://www.bluefish.se \"Department of Redundancy department.\" -- ThinkGeek

Hi! "Brent Vukmer" <bvukmer(a)blackboard.com> wrote: > I think SqueakMap looks really, really cool. I think it would be great if this also store feature requests / bug reports, and associated change sets, for a given package or module. Feature requests and bug reports: Sure! Sounds like an interesting capability. We just need it to be simple. I am thinking if we could just add some sort of general "annotation" feature and then the user use the categories to classify those annotations into "bug reports" or "feature requests" or "bug fix" etc. And if these annotations could also be linked together in threads we would solve a whole bunch of problems using one single mechanism. Example 1: I just saw that Chris has a typo in his summary - "mutliuser". I can't change his registration since I don't have the password (well, if I am one of the administrators I could of course but let's say I am not). But I could just enter an "annotation" using a simple Form at the bottom of the package presentation page and classify that annotation as a "Registration comment" (given that such a category exists of course). Chris could also (when entering the registration) choose what annotation categories he would like to be email-notified about. So given that he elected to be notified about "Registration comments" he would get an email with the annotation and a link to it. Example 2: I detect a bug in Magma and would like to file a bug report. We could set up SqueakMap to listen to the mailinglist and to collect bug reports that has the UUID of the package in them. Or you could simply add an annotation like above but classify it as "Package bug report". Given that we have a nice set of "flags" on annotations, Chris could later - when the bug has been fixed - change the state for the bug report annotation and perhaps even add an annotation himself as a "reply" to it. All in all such an annotation system would look a tiny bit like Hypernews but simpler and with some extra whistles so that it can handle bugs and fixes etc. Will think about it more. The annotations would typically not be stored together with the current map because you wouldn't always want to synch all that down. But we could simply add another logfile for such "extra info". And the next thing you mentioned: To be able to store associated files. Sure, we could add that capability too. regards, Göran

This is what we did recently. Got the image down to 6.0Mb and the download for both Linux and Win32 including VM etc to a 3.2-3.5Mb zip-file.

Well, when Modules start working we can forget about shrinking (to a large extent at least) and start with a really tiny kernel image and then simply just load it up with all the Modules needed. And to do partitioning like in 2) above you would instead use ImageSegments which are really fast to load. regards, Göran
