[Pharo-project] is there an easy way to know the SmallInteger instances?
by Mariano Martinez Peck Dec. 2, 2010

Dec. 2, 2010

If I do SmallInteger alIInstances I get an empty array, and of course, with SmallInteger instanceCount I get zero. Now, I can understand that from the VM point of view, but for the final user, this should be polymorphic. For example, for instanceCount, I would like to know all the "variable slots" that has a 1 in the last bit. Is this already possible? if true, which message? if not, should I hack in the vm and code a primitive that does this? And the same for allInstances, if I can inspect 5, I should be also to inspect SmallInteger allInstances, and SmallInteger allInstances first, etc.... thanks Mariano

by Denis Kudriashov Dec. 2, 2010

Dec. 2, 2010

Hello, I need implement remote updating some dll's for running pharo application. This dll's used by FFI. I want done this by unloading dll from VM. Then loading new updated dll. And then continue app execution. Is it possible? Or only way is to restart pharo?

Re: [Pharo-project] Changesets with LF/CRLF instead of CR?
by StÃ©phane Ducasse Dec. 1, 2010

Dec. 1, 2010

ok stefan as a general principle, I'm open to change for the better :) Now how much? - cost to do - cost of impact - who is helping to fix bugs after - is community happy? For lot of changes we (me myself and I and a couple of others) take the cost and assume the risks. Now you see my question arriving? Are you in charge, committed (SCRUM reference to the pig and chicken story) ?

[Pharo-project] [ANN] New Smalltalk VM Beginners mailing list
by Mariano Martinez Peck Dec. 1, 2010

Dec. 1, 2010

Hi everybody. We want to announce that we've created a mailing list called "Smalltalk VM Beginners" where all the people interested in VM can share knowledge. The aim of this mailing list is create a good and positive energy and spread the knowledge around the Squeak VM. If you always wanted to know something on the VM but never dare to ask, join the mailing-list, may be we will not know it but we will try hard to learn it together. The idea is that we can help each other, welcome people to learn about the VM, and increase and share the knowledge about it in the community. Everybody can ask questions, everybody can help. This mailing list has more or less the same idea of pharo-users or squeak-beginners. Now, to clarify the objectives of the mailing list, we propose some requirements: - Be polite, respectful. - No question is stupid and all questions are welcome. We welcome the most basic questions someone can ask about the VM like, "is it written in C?" "How can I download the code?" - This mailing list should be useful for people that are just interested in knowing a little about the VM, to those who want to know how certain things are done, and specially for those that are learning about the VM because they need to extend or modify it. - If you have a heavy question, you will probably not get the answer in this mailing-list but this is not a problem you can ask in the Squeak VM mailing list. - The idea is that we can help each other. So, the link to the mailing list is: http://lists.squeakfoundation.org/mailman/listinfo/vm-beginners Address: vm-beginners(a)lists.squeakfoundation.org. Cheers

[Pharo-project] [OSProcess] Proposal for Pharo 1.2 compatibility
by Cyrille Delaunay Dec. 1, 2010

Dec. 1, 2010

Hello, I would suggest to replace the two methods -------------------------------------------------------------- OSPRocess class >> platformName "After Squeak version 3.6, #platformName was moved to SmalltalkImage " ^ ((Smalltalk classNamed: 'SmalltalkImage') ifNil: [^ Smalltalk platformName]) current platformName OSPRocess class >> osVersion "After Squeak version 3.6, #osVersion was moved to SmalltalkImage " ^ ((Smalltalk classNamed: 'SmalltalkImage') ifNil: [^ Smalltalk osVersion]) current osVersion -------------------------------------------------------------- by: ------------------------------------------------------------- OSProcess class >> platformName ^ ((Smalltalk classNamed: 'OSPlatform') ifNil: [ (Smalltalk classNamed: 'SmalltalkImage') current ifNil: [^ Smalltalk platformName]]) platformName OSProcess class >> osVersion ^ ((Smalltalk classNamed: 'OSPlatform') ifNil: [ (Smalltalk classNamed: 'SmalltalkImage') current ifNil: [^ Smalltalk osVersion]]) osVersion ------------------------------------------------------------ to avoid deprecation messages when using it in Pharo 1.2. Does it looks good? I'm not able to publish on the squeaksource repository

Re: [Pharo-project] Transforming WSDL in a local model - Which HTTP client ? (was Web Services - SoapOpera problems)

That's not quite what happened, the SAP Connect relies on the WS stack to do the WS part, it adds SAP specific integration, and yes it also provides the alternative proprietary RFC protocol as well (not everything in SAP was exposed via WS at that point). Anyway, I can certainly sympathise with the sentiment expressed in this thread. IMO, CORBA comes out as the pinacle of simplicity when compared to the WS stack as it is today. The problem is not just the sheer number of specs, but also the laxity and vagueness of individual specs themselves. There's so much room for different interpretations of everything that interoperability beyond trivial examples is nearly impossible (generally the small monkeys just have to ape what the few gorillas decide to do). Anyway, the easiest in this case likely is to simply observe the communication of the PHP based solution and implement just that specific protocol. Each WSDL spec basically defines (whatever that means in the WS context) a custom protocol, you need just one of those, not all of them.

[Pharo-project] Protocol Buffers anyone?
by GÃ¶ran Krampe Dec. 1, 2010

Dec. 1, 2010

Hi! I want to build an API for Riak (awesome NoSQL db) and there is a choice of using HTTP or Protocol Buffers. Evidently Protocol Buffers offer a quite higher degree of performance so I am leaning towards that. Now, has anyone dabbled with implementing Protocol Buffers for Squeak/Pharo/Smalltalk? Couldn't find anything. regards, GÃ¶ran
