ESUG = Edinburgh Airport

by Benjamin

Is there some of you who will arrive at the Edinburgh airport around 17h ? Because Jannik Laval and I will be there, so if we can share a taxi and be a bit less lost, it could be cool :) Ben

Memories about an ESUG talk: Smalltalk's Image Problem

by Offray Vladimir Luna CÃ¡rdenas

HI all, I was making a talk here in Colombia trying to invite people to conform a Smalltalk study group. I was showing them Pier and Seaside as "selling points" for making a project and there is some initial interest. The typical questions about: * If Smalltalk is so good, why is not widely known ? * Which famous/big project is made with Smalltalk ? where in place. I think that Pier, Seaside, Etoys, Scratch, DrGeo, Croquet, are really good projects to motivate people towards learning Smmalltalk, but they're kind of "niche" projects (I have no problem with that), but searching for information about who to solve these questions I found this talk on ESUG 2009: http://www.esug.org/Conferences/2009/Current+List+of+Talks/Smalltalk%27s+Im… So I wonder if anyone has the memories/slides of this talk and, of course, what community thinks about these questions. Thanks, Offray

Fwd: [ANN] Fuel release version 1.6

by Mariano Martinez Peck

---------- Forwarded message ---------- From: Martin Dias <tinchodias(a)gmail.com> Date: Fri, Aug 19, 2011 at 6:14 AM Subject: [ANN] Fuel release version 1.6 To: esug-list(a)lists.esug.org, pharo-project(a)lists.gforge.inria.fr Cc: Mariano Martinez Peck <marianopeck(a)gmail.com> Hello! I want to announce the new release version number 1.6 of Fuel, a binary serialization framework for Pharo that provides extremely fast deserialization. More information on our home page<http://rmod.lille.inria.fr/web/pier/software/Fuel>. Again, I thank ESUG for sponsoring me through the SummerTalk<http://www.esug.org/wiki/pier/Promotion/SummerTalk/SummerTalk2011>program. You can download this version in Pharo 1.2.1 with: Gofer new squeaksource: 'Fuel'; package: 'ConfigurationOfFuel'; load. ((Smalltalk at: #ConfigurationOfFuel) project version: '1.6') load. This version does not add any new concrete functionality but has two main achievements: a performance improvement and a design clean up. Many changes included in this release are part of a design clean up. They are a necessary step forward to new functionalities that are coming soon. They make code more understandable. They enable simpler extension. Happily they also helped to improve serialization performance by reducing unnecessary interactions. And it is specially important a bottleneck in graph analysis stage we have successfully attacked, obtaining great results. Details: - Removed explicit references to cluster classes scattered around the system. For example, in previous versions Float>>fuelCluster has an explicit reference to FLFloatCluster. This version replaces this by a double dispatch interaction. - Clusters: Better reification. Removed annoying IDs. Removed Singleton instance creation mechanism, now mappers manage uniqueness in a better way. - Mappers: They were simplified. New mapping machanism inspired on Chain of Responsibility pattern. The global objects detection has been optimized considerably. - Analyzer: Part of its behavior and state has been moved to a new abstraction called 'clusterization'.

For sqlite, squeakdbx should call the sqlite api to retrieve column datatype for each row and each colum while fetching data. Hi Alain. I am reading this: http://www.linuxnetworks.de/doc/index.php/OpenDBX/C_API/odbx_column_type From SqueakDBX, we send odbx_column_type ONCE PER RESULTSET. You can see this in #processNextResultSet:querySettings: that for every resultset it sends #processResultWithRows:resultHandle:querySettings: Now.... should we send odbx_column_type and friends ONCE PER RAW? As far as I can see, in other databases we don't need to do that. But maybe we are wrong and you are right. Norbert? Anyway, if you want to give it a try to Sqlite, what about overwrite #moveNext: in SqlitePlatform and do something to set the new type for every raw. From what I can see, if the type depends on each raw and it should be asked for every raw, then a design change is needed so that we can move the description from the REsultSet to the Raw :) But it may have implications I don't know. Perhaps squeakDbx could get only true object values (are rawValues really needed) ?. Well, it depends on the user needs. Now, a key point is what GLORP should use. Or perhaps another solution would be to call the sqlite api if the stored datatype is UNKNOWN in column description ... (only for sqlite, but sounds like a bad trick) sounds like a hask, but if it works it is at least a valid workaround. I am perplexed ...

Re: [Pharo-users] DBXTypeNotSupoorted with Glorp

by Alain Rastoul

Hi, I finally found that when called in C with the same api calls that those made by opendbx, sqlite correctly returns datatype of columns when fetching rows, the problem is clearly that the data type is stored in SQueakDBX column description for the resultset the first time it fetches the first row. For sqlite, squeakdbx should call the sqlite api to retrieve column datatype for each row and each colum while fetching data. But it may have implications I don't know. Perhaps squeakDbx could get only true object values (are rawValues really needed) ?. Or perhaps another solution would be to call the sqlite api if the stored datatype is UNKNOWN in column description ... (only for sqlite, but sounds like a bad trick) I am perplexed ...

cascaded update of objects with Glorp

by Alain Rastoul

Hi, I am trying to update a composite object in a database with Glorp. I have a Customer object with a reference to an Address object. In my seaside app, I have a ListView that calls a CustomerEditView when I click on a customer. with: edit: aCustomer | response | response := self call: (self editor new model: aCustomer copy). response ifNotNil: [ self session database update: aCustomer with: response]. (database is a is a facade to the Glorp system, and update: anObject with: anotherObject perform the variable instance assignments of an object to another in a glorp unit of work). when I click on Cancel button in my CustomerEditView, the address is modified in the list with what has been typed in the form. (a shallow copy points to the same Address object) so I tryed: ... model: anObject deepCopy ... And I have a DuplicatePrimaryKeyException in Glorp when I click on the save button, because Glorp don't want to have two different objects with the same primary key - that makes sense. Do anyone know a way to do this in Glorp without updating each field of the linked object (in the final model, I will have 3 addresses), ie, doing the update cascade in a simple way. I am thinking about implementing an updateFrom: anotherObject or copyTo: anotherObject in my Customer and Address objects but it does not fit right with basic types (String, integers etc) and I am sure someone had the same problem before me. Any idea, comments or suggestions are welcome Thanks in advance, Cheers, Alain

If anyone has 5 minutes to kill having a look and give some feedback, I'd appreciate it. It's in squeaksource - I think I set it up so anyone can see it ... let me know if it isn't (and how to make it visible too! :) It only has an add function so far (and the page search is only linear - I'll get to that). useage x := BTree withOrder: 2. x add: 11.

Re: [Pharo-users] MAConditionError opens a debugger

by laurent laffont

Romain I've looked at it. The problem is that SeasideHosting (thus SmallHarbour :) is rather old and Magritte seems to be used in an obsolete way. So the MAConditionError is not catch anymore by (removed in Seaside 3) MAValidationDecoration>>processChildCallbacks: So I put an ugly hack in SHLoginComponent waiting for rewriting it the right way (but not now too tired).
