[Pharo-project] Help mapping large database objects to Smalltalk objects

by Mariano Martinez Peck

Hi folks: I started to code a bit the large support for SqueakDBX to large objects and I want to ask you for help. In a first step, I will start with the basic large objects: CLOB, NCLOB, XML, BLOB. Now, I need to map each of them, to an Smalltalk object. I though about this: CLOB -> String NCLOB -> String XML -> String and the the user do whatever they want with the string representing the XML. BLOB -> ByteArray what do you think? are there suitable objects in a core image ? (I don't want to depend in another package) Now, do you know which is the faster why to create a ByteArray from a String ? and vice-versa ? just asString ? Another question....to get a field value of a row, I call an OpenDBX using FFI like this: apiQueryFieldValue: handle index: index "const char* odbx_field_value( odbx_result_t* result, unsigned long pos )" <cdecl: char* 'odbx_field_value' (ulong ulong) module: 'opendbx'> ^self externalCallFailed As you can see that function of OpenDBX answer me in a char* the value of the field. The problem is...suppose that field is a large object (a CLOB for example). A Clob can be 1gb or even more....of course, that will be bad for my image (freeze ? crash ? I don't know...). I would like to validate the size of that before bring it into the image, so that not to crash or whatever. I want to put like a limit. The problem is that I don't know how to do that from Pharo side....is that possible ? or the only way is to change OpenDBX side ? Thanks a lot in advance, Mariano

[Pharo-project] about and:and:and:and: and or:or:

by StÃ©phane Ducasse

hi all Jannik and jb started to replace all the and:and: and:and:and: and:and:and:and: and the same for or: by they equivalent ie 1 =2 or: [ 1=3 ] or: [1=1] => 1 =2 or: [ 1=3 or: [1=1]] the new compiler optimize both while the old one not. So now I would like to see what do you think. Personnally I do not like and:and:and: and more Now for and:and: I'm hesitating. Stef

[Pharo-project] adding traits programatically

by Esteban Lorenzano

Hi, I'm trying to add/remove traits from a class programatically and I have a problem... What I'm doing is, for instance: NSProxy traitCompostition: TNSLogConsole. and NSProxy traitComposition: TNSLogNone. (as a way to replace logging strategies)... but nothing happens... bah... in the browser the class definition is affected, but the application still works as if none changed... do I need to force a class recompilation after changing trait composition? what I'm doing wrong? Cheers, Esteban
