Re: [Pharo-users] Experiences with non RDBs?

by Norbert Hartl

Hi, I think I don't need to refer to your concrete example. Basically an object is a named key-value store. So a class A with instance variable a,b,c is just something like A a -> valueOfA b -> valueOfB c -> valueOfC A subclass of A would either have the same amount of variables or more. So subclass B of A could look like B a -> valueOfA b -> valueOfB c -> valueOfC d -> valueOfD If you have a serialized form of a B you need to know that it is a B in order to read all of the 4 values back into the right object type. - in OODBs this case is easy. The serialization contains everything from the key-values and the class that they belong to. Sometimes the data format on disk is the same as in memory so there is less to do. The difference between magma and gemstone is that magma is an addition to an image. That means you have your smalltalk image in memory and than you have magma. With magma you define a persisted root object, e.g. a Dictionary. Everything you attach to the Dictionary will be persisted if you do a commit. Well, you need to do your changes inside a transaction but there are always ways to make this look nearly transparent. In gemstone everything is already persisted including all the classes and objects. As soon as you attach a newly created object somewhere that is already persistent it will be persisted, too. The easiest way of handling your data is to keep an instance variable in your class that holds the instances. Et voila, that's all! All you objects are persisted. Speaking of seaside gemstone can be used doing autocommits on a request basis so you don't have to care at all about transactions. You just use your objects and that is it. Querying is like using collections. If you need special kind of querying either for your problem or performance you can provide a special type of collection that is optimized for the problem - In XMLDBs / document databases (CouchDB) you just have a representation of that key-value store. Be it an xml element or a Javascript object in JSON format they are both key-value stores. You then need to serialize/deserialize those formats. Reading a subclass is just a matter of providing the right class name when reading the serialized format. References can be handled multiple ways, but default ones will be id/idref in XML and link/Uri in restful ways. Querying in XMLDB is using xpath, in CouchDB and document databases I don't know if there is a general query support - In SQL databases the instance variables are mapped to columns of a table or multiple tables and each row is an object. Relationships of objects are handled by keys in the tables. A 1:1 relationships contains a key of the relation source in the relation target table. A n:m relationship needs an intermediate table that maps relation source keys to relation target keys. Talking about inheritance this gets easily complicated. Basically there are two options. You can solve it like everyone would expect it, let's say more BNF like. You would have a table A for class A and a table B for class B. Now in all tables of objects that reference A or B you need an additional information which class is meant: A or B. The tables than could be joint correctly after evaluation the additional value. Another strategy is to do multiple lookups until you've found the right value. The other approach is to make one table that is a super set of all needed variables. The keys are unique among all the subclasses and can be lookuped up more easily. But you waste some space because a lot of the columns would be empty. In any case you need to change your database schema if you change your model. Joins and number of requests can grow easily so that your application will be slowed down. Glorp gives you all of these strategies if you want them. My personal advize would be to avoid inheritance in that scenario completely or do only the simplest cases possible. Relational databases and object oriented approaches just don't fit together. You need to decide if your problem is more of the one or the other type. Then take one of those two approaches. Querying is based on column types and joins. Glorp is providing a query protocol that is similar to collections. You just need to use some things differently due to the nature of the layer below is different.

You need to care only about your data model, and can do anything, what naturally you want to do with your data. OODB handling all of it behind the scenes. All what is you have to do is to designate the transaction boundaries, where you dealing with data, so you can abort /commit it at some logical point. The rest of stuff can be used without caring about persistence - you working with objects as if they are just objects , as if you having your data in image. As simple as that. Of course, there are indexes and other helpful stuff, which could help you work more efficiently with larger data sets, but it is optional. So, while in RDBMS your are a servant of database (because you have to follow all requirements for every query/data model you put there), with OODB - it is a database your servant and doing everything for you, without much interference and without dictating you how your data structures should be organized. So, i think this answering your question about inheritance: if you need inheritance, just use it. :) > Regards > Friedrich > > -- > Q-Software Solutions GmbH; Sitz: Bruchsal; Registergericht: Mannheim > Registriernummer: HRB232138; Geschaeftsfuehrer: Friedrich Dominicus > > _______________________________________________ > Pharo-users mailing list > Pharo-users(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-users > -- Best regards, Igor Stasenko AKA sig.

Re: [Pharo-users] Experiences with non RDBs?

by Norbert Hartl

And I'm using gemstone :) All of the persistence solutions have specialities that make them useful. Be it - GOODS that is supposed to be language neutral. You can share your objects between smalltalk and java e.g. - Magma is smalltalk only but full-featured OODB that is easy to set up and it is quite powerful. For server deployment I can't say. It is that Chris always states that you can achieve decent performance but other people always complain about its performance - CouchDB/document databases. Is also kind of language neutral. When "just persist and query" is your main concern (which is it most of the time) than CouchDB might be a good choice. With this you can access your objects from either the server or from the client using javascript. Should be fairly ease to do - gemstone if you consider persistence as just a necessity because your memory is not persisted by default and it is too small to keep everything. Or in other words if you just want to care about _your_ problems and not the problem of the persistence ;) - SQL to integrate legacy application or to feature a business problem that is relational in its nature which OO problems are not per se - XMLDB if your problem domain is not only about document but about XML documents and X**** search capabilties. And there a lot more that are combinations of any of the above etc. Norbert On 07.04.2010, at 12:36, StÃ©phane Ducasse wrote: > I know > > Inceptive.be is using GOODS. > Hilaire used magma > Netstyle.ch postgres > > Now this is easter holidays here so people are busy eating chocolate. > > Stef > > On Apr 7, 2010, at 8:41 AM, Friedrich Dominicus wrote: > >> I just wonder about experiences with non relational databases like e.g >> - Magma >> - Gemstone >> - others >> >> and/or limits of the diverse ORM mappers. >> - Glorp >> - Magritte >> - others >> >> Regards >> Friedrich >> >> >> -- >> Q-Software Solutions GmbH; Sitz: Bruchsal; Registergericht: Mannheim >> Registriernummer: HRB232138; Geschaeftsfuehrer: Friedrich Dominicus >> >> _______________________________________________ >> Pharo-users mailing list >> Pharo-users(a)lists.gforge.inria.fr >> http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-users > > > _______________________________________________ > Pharo-users mailing list > Pharo-users(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-users

It is just classes. If you want to develop your "home office" separately from your "study" then you should look to put them in separate packages that you can load separately. However, consider your dependencies carefully.

And... I'm good with OOP (and I read every book about OOP and Smalltalk I could get my hands on, including a few of yours, and enjoyed them all). What I'm not grokking is: my understanding of Squeak (which I applied to Pharo) from all of Alan Kay's work is that it's moving closer toward an "application-less" virtual world, where all objects can communicate with all others - instead of Microsoft Money holding my financial data hostage in a proprietary data file, and Apple holding my notes in Mail.app data files, *I* hold all these objects (and the system itself), all written in Smalltalk, so I have complete control over my computer world. Now... what I am curious about (and haven't found a book to address), is what (if any) are the strategies one uses to conceptually make sense of a virtual world of possibly thousands of (normally, mostly) unrelated objects. For example, 9 out of 10 times, I probably don't care that I have journal entries alive in my image when I'm processing receipts, but the one time I want to cross-reference the journal for keywords for certain purchases, I want access to them. And all I've seen in reference books is how to develop "an application" in Squeak/Pharo i.e. code that does one conceptual thing e.g. moves a turtle, rolls a die, creates a laser game - which were all totally great, and also did not give me any insight to this particular question. Maybe it's something really obvious to a long-time Smalltalker that no one's bothered to write down?! Thanks again. Sean

Re: [Pharo-users] Projects/Project Windows

by Mariano Martinez Peck

Hi Sean. As Stef said, Projects were removed from Pharo. Not completely yet. I guess you are using a PharoDev image. Those images are based in PharoCore 1.0. You can take Project class and look the references. If you take a look at PharoCore 1.1 images and look for references, you will see there are a lot less. But sill, the class is present and it has only one instance.

In Squeak, this was the mechanism I used to keep objects from different domains separate, but the amazing Smalltalk beauty of it was that the objects could talk and act across the boundary. I was building a utopian digital world without the artificial boundaries of "applications." Is there a similar (or better) mechanism for this in Pharo? For example: If I was using an image for all my personal computing, and I wanted to manage both my personal accounting and my journal; in Squeak, I would create a MyMoney project and a MyJournal project. How would you handle this goal in Pharo? My objective is to have every domain object in my life be able to communicate with every other object, without having one huge, unmanageable pile. Maybe keep the objects in repositories stored in class instance variables in top-level project-like objects?

Projects/Project Windows

by DeNigris Sean

How do you create Projects in Pharo? In Squeak, you can select "new morphic project" from the world menu. I found out how to do the same thing programmatically: > Project newMorphicOn: nil. The SystemWindow appears - great, no problem; except... I can't figure out how to enter the project. When I click on it (which would enter it in Squeak), nothing happens. I tried a bunch of other stuff, but couldn't make it happen. Thanks! Sean p.s. more generally, is there a way to get removed Squeak world menu options through the GUI?

If the "default" doesn't satisfy your needs, then yes. There is no need to explicitly look the code. You can just inspect for example: (ConfigurationOfO2 project version: '1.2') groups Then, you can inspect a particular group, and inspect the result of the message "includes" to see what it is included in such group.

Lot of things in Squeak looked cool but was introducing a lot of spaghettis code and maintainability problems. If somebody implement good flap for Pharo we may integrate them.

So, when I click Configuration -> show shared tabs menu option I get this error: ======================================================================= MessageNotUnderstood: Project>>currentToggleFlapsSuppressed Project(Object)>>doesNotUnderstand: #currentToggleFlapsSuppressed [] in ToggleMenuItemMorph(MenuItemMorph)>>invokeWithEvent: BlockClosure>>ensure: CursorWithMask(Cursor)>>showWhile: ToggleMenuItemMorph(MenuItemMorph)>>invokeWithEvent: ToggleMenuItemMorph(MenuItemMorph)>>mouseUp: ToggleMenuItemMorph(MenuItemMorph)>>handleMouseUp: MouseButtonEvent>>sentTo: ToggleMenuItemMorph(Morph)>>handleEvent: MorphicEventDispatcher>>dispatchDefault:with: MorphicEventDispatcher>>dispatchEvent:with: ToggleMenuItemMorph(Morph)>>processEvent:using: MorphicEventDispatcher>>dispatchDefault:with: MorphicEventDispatcher>>dispatchEvent:with: MenuMorph(Morph)>>processEvent:using: MenuMorph(Morph)>>processEvent: MenuMorph>>handleFocusEvent: [] in HandMorph>>sendFocusEvent:to:clear: [] in PasteUpMorph>>becomeActiveDuring: BlockClosure>>on:do: ======================================================================= How do I get around this issue to have Pharo display the Shared Tabs? Any help is really appreciated. Thanks.

Using FFI on linux 64 bits

by Daniel Galdames G.

Hi, i was trying to use FFI plugin on a 64 bits linux, but when I try the test, or FFI-Examples, the vm crash with a segmentation fault. I was able to use FFI with a i686 vm, calling 32 bits libraries. Is there any way to make a 64 bits vm to call 64 bits libraries? or it isn't supported yet? Thanks. Daniel Galdames G.

Re: [Pharo-users] ecompletion and new browser

by Mariano Martinez Peck

Hi Yoandy. How did you install O2 ? If you see in the welcome worspace of the image you are using, it explains how to load O2, which is: Gofer new squeaksource: 'MetacelloRepository'; package:'ConfigurationOfO2'; load. ((Smalltalk at: #ConfigurationOfO2) project version: '1.2') load: 'Dev'. Can you confirm that installing it in that way, still the autocompletion doesn't work ? because it should Cheers Mariano 2010/4/2 Yoandy RodrÃguez MartÃnez <yrodriguezma(a)uci.cu> > Hello: > I've downloaded the new Pharo image (Pharo-1.0-10515-rc3) from the site and > just learned to use Metacello and Monticello (thanks to Stephane and Mariano > btw).

ecompletion and new browser

by Yoandy RodrÃguez MartÃnez

Hello: I've downloaded the new Pharo image (Pharo-1.0-10515-rc3) from the site and just learned to use Metacello and Monticello (thanks to Stephane and Mariano btw). This image comes with a different browser that the one I was using before so after a little searching I found O2 and got it from Squeaksource but now the completion plugin it's missing from the browser. how can i fix this? thanks in advance.
