This is a long known problem: http://code.google.com/p/pharo/issues/detail?id=2353. For now it can only be avoided by not using WideString (i.e. by not using an encoded server adapter).

Re: [Pharo-users] metacello question

by Dale Henrichs

Werner, I was away on vacation last week and didn't see your question .... If I were to guess, I would say that when you "removed package Pattern" it was not actually removed from the system (perhaps you just removed the class instead of unloading the package?) The package still existing is very suspicious... Metacello will not usually load on top of a dirty package, so when you tried again, the package Pattern was not reloaded ... Metacello will dump information about skipping dirty packages into the Transcript ....

Re: [Pharo-users] **Important Please read** Towards First Class Tasks

by StÃ©phane Ducasse

Hi guys I'm in town. Now I want to make clear the following: This idea is much more on having an effort to collect todo and manage to kill some of them regularly than to engage to for long task. As an example for the UI I would like - layout fixed so that glamour IDE can work - in place edit in list items (for example to be able to directly edit the protocol of a method in a sender list) - an option to get list showing only elements matching an input on the fly What you see is that we should have list of "simple" tasks that people can sign in for. The idea is that we should coordinate a bit to make progress.

Hi list, I'd love to have something like: #(#a #b) combinationsWith: #('one' 'two' 'three') collect: [:i :j | i , ' matches ' , j asString] That returns the collection: #('a matches one' 'a matches two' 'a matches three' 'b matches one' 'b matches two' 'b matches three') In other words, is there some kind of vectorial-product-like method for collections in Smalltalk?

Re: [Pharo-users] detecting and reacting to a race condition/infinite loop

by Werner Kassens

Hi Paul, and everytime you made a coffee and then you went back to your computer it has rebooted, since the ui-interface noticed it was in an infinite loop waiting for your input <g>. but its generally not really possible. consider an object that has a variable i and these 4 methods: Counter>>initialize i:=0 Counter>>inc i:=i+1 \\ 42 Counter>>count 200 timesRepeat: [self inc] Counter>>dumb [self inc. i<50]whileTrue it would not be sufficient to store the state of _all_ variables, the moment one var changes, it would not be sufficient to store the state of the program at this moment (iow that it is in method inc when i gets set to the same value), you would also need to store the history of the program states (iow that it comes from method dumb). werner

Re: [Pharo-users] metacello question

by Paul DeBruicker

Depending on how you load your configuration you might need a line in the baseline that says: spec group: 'Core' with:#('Pattern'). Then try (ConfigurationOfPattern project) latestVersion load or if you've defined #stable: ConfigurationOfPattern load Also in your version10 method do you define what version of Nile you want to load? -- View this message in context: http://forum.world.st/metacello-question-tp3648875p3649112.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Hapao installation

by Romain Verduci

Hello, I tried to download Hapao in Pharo 1.2.2 with the code in the Hapao website : Gofer new squeaksource: 'Spy'; package: 'ConfigurationOfSpy'; load. (Smalltalk at: #ConfigurationOfSpy) perform: #loadDefault When I load the packages, there is a dependency with SubscriptionRegistry package, what is this package ? Finally, when I want to run Hapao in the Pharo menu, there is the following message: MessageNotUnderstood: PluggableDialogWindow>>beResizeable. In fact this message does not exist in the system, is it because of SubscriptionRegistry package isn't load ? Or because I did something wrong ? Thanks for answers. Romain

detecting and reacting to a race condition/infinite loop

by Paul DeBruicker

Is there a way to detect when an image has entered an infinite loop? If so could I then halt it, save the image, and reboot from a previously known good configuration automatically? I have a site with a weird bug on a remote server that has become annoying to debug because when the infinite loop occurs the RFB process becomes unresponsive. Or maybe I should stop running headless temporarily and use X forwarding through SSH. Anyways, is there a way to detect an infinite loop an react to it? Thanks Paul

Pharo showcase demos?

by Simon Denier

Question: what do you show to other people when you want to demo Pharo/Smalltalk? in 15 minutes / 30 minutes / 1 hour Do you have a typical example? Do you use a kata? Or a full blown application? What tools do you show? I'm looking for successful recipes/topos to present Pharo in a technical context: the premice is that people are interested by Pharo, but they will not be convinced by a toy case and a basic demo of tools. A TDD demo would be more efficient I guess. That would be cool to have a list of such showcases depending on the context (duration of demo, technical level of people, interest...) -- Simon Denier

Re: [Pharo-users] Fuel: Could not find a serializer with id=0

by Martin Dias

Yes, we have to work on it. I think version handling should be added wrapping the basic serializer, like other features like a checksum, compression, or encryption. So the class that serializes just worries about serialization. For example, in the Moose extension we are signing the stream with this prefix: 'FLMoose', version where version represents a two-byte integer. A kind of faÃ§ade adds this behavior in FLMooseContainerWriter and FLMooseContainerReader, throwing error when either stream doesn't begin with 'FLMoose', or it is a different version. Implementation of FLMooseContainerWriter and FLMooseContainerReader are questionable, but my point is that I believe version is a meta-information about the stream that can be appended optionally. Do you agree?

Not really. The problem seems to be that the file was not correctly written. Objects are grouped in clusters. So we write the id of the cluster, then the amount of objects of such clusters and finally we write those objects. At materialization, we read the data. In this case, it seems we are reading something different from expected, so we do something like clusterId := stream readInteger to get the id but in fact we are getting a zero, because we are actually reading something different from expected.

Re: [Pharo-users] **Important Please read** Towards First Class Tasks

Hi, The idea of Pharo Tasks is not to get things rigid and to stop the individuals from contributing. This should continue to happen. Instead, the idea is to start acknowledging that Pharo has became larger, and that the integration and drive of individual contributions has more dimensions that can be handled by the core group alone. So, the Pharo Task Force is a mechanism for teams to form around some larger topics. Like I said beforetime, I want to work on the IDE. This is a topic that is larger than one person can and should do. But, it is also a topic that requires integration of contributions, and it won't work by simply doing a union of choices. Just like now the Core team relentlessly cleans up the language and infrastructure, so should the IDE deserve a similar approach to get it strong and reinvented. People should know that this project exists and that they can contribute in a more organized way. This won't work by force. But, if someone wants to build/lead/integrate a project like this, I think it can work nicely.

Are you trying to repeat experience of Squeak teams? I can remind you that they are never worked and failed in the end. And i think that problem is that its hard to coordinate people which are located around the globe and their main tasks are completely different. Another reason is that you cannot enforce any kind of responsibility for delaying or not delivering , because we're talking about enthusiasts. I believe that individual people with own vision and own, personal, agenda could do much more. If someone would like to voluntary coordinate some activities, i am all for it. Now this means that given person should have plan in his head and stick with it, and keep an eye, ask around, communicate, and of course try coordinate people. But is it really need to be formalized like that? We, as community could discuss the agendas, and then a concrete steps to implement it. Now, its not really matters who will do it, as long as there enough people interested in helping with it. And its completely pointless to form groups of individuals, only to be listed as a group member on site and doing nothing (for whatever objective reason). So, the right questions about any improvement, which we would like to see in future is: - do/why we need that - who can do that if both of these questions can be answered positively, then it is only a matter of time for new feature to appear. And to my opinion, putting any kind of formality around it is completely orthogonal to what will happen in reality. -- Best regards, Igor Stasenko AKA sig.
