Fwd: [Cuis] ProcessSpecificVariable and DynamicVariable

Hola gente!
Ayer lei este email de maese @garduino. No entendi el ejemplo, donde se usa ahi ProcessSpecificVariable o DynamicVariable? Que es ProcessSpecificVariable? Me imagino algo como thread local storage Que es DynamicVariable? Gracias por cualquier info Nos leemos! Angel "Java" Lopez @ajlopez gh:ajlopez ---------- Forwarded message ---------- From: Germán Arduino <[hidden email]> Date: Mon, Dec 17, 2012 at 11:23 PM Subject: [Cuis] ProcessSpecificVariable and DynamicVariable To: [hidden email] Hi Juan, List: In Pharo and Squeak exist the classes of the subject. A common use is a the way that follow: ZnConnectionTimeout value: 5 during: [ ^ ZnClient new get: 'http://zn.stfx.eu/zn/small.html' ] These classes are not present in Cuis and I not found nothing similar to try the same thing. Even the Process in Cuis have different methods and as I don't know this part very deep I want to ask what should do the correct way here. I should implement this classes and the missing method in Process? Or I should use other classes already present in the Cuis image to achieve the same goals?

Hola Angel:
La verdad que yo tampoco tengo muy claro exactamente porque hay una clase para esto que sólo la usa Zinc y nadie más (al menos dentro de la imagen base). Después con más tiempo voy a mirar los test que vi que hay en Squeak.

Interesante!
Supongo que se puede simular con un dictionario que tenga como clave un proceso, y como valor el valor que buscas. Me imagino a mano alzada: Object subclass: #ProcessSpecificVariable instanceVariableNames: 'dict' .... ! !ProcessSpecificVariable methods! initialize dict := Dictionary new "no tengo aca como se llama un dictionario tipo hashtable en Smalltalk" ! value ^dict at: Process current "tampoco se si es Process current o algo asi, y agregaria algun ifAbsent: [^nil]" ! value: aValue dict at: Process current put: aValue ! ! Y DynamicVariable? Tambien es de Zinc? Relacionado con ProcessSpecificVariable o para otra cosa? Nos leemos!

Sip, fijate ProcessSpecificVariable >>value
^Processor activeProcess environmentAt: self ifAbsent: [self default]. (Y default es nil). DynamicVariable hereda de ProrcessSpecificVariable, pero no es de Zinc entiendo yo (están en Pharo y Squeak con diferentes implementaciones). Por otro lado, lo que decia que me sonaba extraño es que no encontré en las imágenes base otros usuarios de esas clases, así que supongo que son para paquetes externos. Pero francamente, no conozco como surgieron estas clases, el porque, las motivaciones y más aún ¿por qué están en la imagen base si no se usan? Lamento no poder aportar mucho más por ahora.
