[Magma] Error creating a Repository
by Hernan Wilkinson 01 Aug '02

01 Aug '02

Hi, I just donwloaded Magma and installed it. I tried to create a repository just as the example shows, MagmaRepositoryController create: 'c:\temp\myRepository.magma' root: Dictionary new but I get "UndefinedObjects are not indexables" becuase requestPrototypes is nil... Am I missing something? Do I need to do something else before creating a repository? Thanks, Hernan. __________________________________________________ Do You Yahoo!? Yahoo!

RE: Has anyone bothered to check out SqueakMap?
by Brent Vukmer 01 Aug '02

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. -----Original Message----- From: Göran Hultgren [mailto:goran.hultgren@bluefish.se] Sent: Wednesday, July 31, 2002 7:53 PM To: squeak-dev(a)lists.squeakfoundation.org Subject: Has anyone bothered to check out SqueakMap? 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

Re: [ANN] Introducing Magma, an object database for Squeak
by goran.hultgren＠bluefish.se 01 Aug '02

Ok, I am hammering in postings right now but what the heck. Chris - have you run any load tests or regression tests? I mean - how stable would you say Magma is right now? Or some benchmarks like filling it up with gazillions objects, doing senselessly many transactions etc? I am terribly tempted to use it - not for SqueakMap though because it is too large as a dependency for SqueakMap. But for just about every other project I can think of... :-) regards, Göran

Hi again! Btw, here is a simpler variant on your load.ws with a prompter (load.st might be a more suitable name I think), I think it is equivalent actually: | path | path _ FillInTheBlank request: 'What is the path to the Magma changesets? (end with delimiter)' initialAnswer: (FileDirectory default pathName, FileDirectory slash). #( 'MaExceptionExtensions.8.cs' 'MaBaseAdditions.82.cs' 'MaTraversingObjectGraphs.28.cs' 'MaMinimalObject.15.cs' 'MaObjectSerialization.1.cs' 'MaClientServerSupport.88.cs' 'MaArmoredCode.32.cs' 'MaSpecialCollections.26.cs' 'MaDynamicInstanceVariables.13.cs' 'MagmaClient.26.cs' 'MagmaServer.27.cs' 'MaSqueakDomain.41.cs' 'MagmaTester.36.cs') do: [:fileName | (FileStream oldFileNamed: path, fileName) fileIntoNewChangeSet] regards, Göran

I agree with Dan on that. I tried MVC on a 3.2 gamma but found some problems (bugs ?) then I returned to old and reliable 2.8. Yes, I want to move to 3.2 with MVC as soon it works smoothly. cheers, #Jean.

I believe it may be the case that MVC users also tend to use stable releases, and therefore many may still be using 2.8. So if you are or might be an MVC user, in addition to answering Scott, please say... What release do you use now? Do you plan to move to 3.2 in the near future? Thanks - Dan

A couple of quick ones: "Optimistic locking offers reduced concurrency..." - that should be "increased", right? And the other way around at: "Pessimistic locking increases concurrency...". Ah, I see you have a somewhat different definition of the word "concurrency" at http://minnow.cc.gatech.edu/squeak/2666 That might be confusing. As a sidenote GemStone sends "events" to the clients when they ought to "cross" as you call it. And if they don't follow that advice they are finally "forced to abort" or something like that I think. Btw, at Swikipage 2639 " simulteneous indexes" should be "simultaneous indices". I think. :-) The page was locked so... At page 2638 the "Two kinds of ReadStrategies" seems a bit incomplete. Perhaps you could proof read that again. In the example - where do you specify the instance variables and their levels? If I am not mistaken there is also another "nitpicky" variant of conflict that I assume you have ignored - if transaction A reads object foo that has been changed by transaction B after A started. I believe GemStone calls that a "read conflict" or something. The idea being that logically transactions "occur in full" at the time of their commit and transaction A should not be permitted to depend on a "stale" value in foo. IIRC GemStone has some kind of "full checks" or something that you can turn on when deploying to enable this nitpickyness. Whatever, just thinking aloud. :-) ...ok, now I have read through all swiki pages I could find and darn - this sounds pretty great! Actually if it is as good as it sounds :-) it is one of the most exciting things in Squeak for a loooong time! I am ecstatic. Hmmm, I will look into perhaps using this for SqueakMap... Ah, now I just read about the license! Good. I sortof gathered that since you have used the Swiki to document it. :-) regards, Göran

Hi, I just grabbed the file /Smalltalk/Squeak/3.2/unix-linux/Squeak-3.2-sparc-sun-solaris2.8-3.2-4.tar.gz from st.cs.uiuc.edu. gunzip complains about an unexpected end of file. Yes, I made sure that I did a binary transfer. -Dwight

Making external plugins as shared libraries on OpenBSD?
by Craig Latta 01 Aug '02

01 Aug '02

Hi-- On OpenBSD 3.1, it seems that Unix Squeak 3.2-4 creates static libraries for external plugins (.a files), not shared-object libaries (.so files). What change should I make to the build machinery to make external plugins that I can load dynamically? thanks, -C -- Craig Latta improvisational musical informaticist craig(a)netjam.org www.netjam.org Smalltalkers do: [:it | All with: Class, (And love: it)]
