[Pharo-project] Committing on dead squeak source freezes to death my system
by StÃ©phane Ducasse Nov. 5, 2012

Nov. 5, 2012

Hi I thought that there was a timeout to reach a server and that after I could get back the system. Right now I cannot. I'm using the latest pharo2.0 and I could not unfreeze it. Any idea suggestions? Stef

[Pharo-project] Are the any Fuel file analysis tools/techniques?
by Yanni Chiu Nov. 5, 2012

Nov. 5, 2012

This scenario has happened a few times... Stuff is serialized and de-serialized (to/from files) without problem. Code changes are made. At some later date, I notice that the Fuel file is orders of magnitude bigger than it used to be. I usually manually de-serialize, and navigate the structures until I find the cause of the bloating. Is there some package or code snippets that can quickly summarize the object classes and sizes in a serialized file, or from its in-memory de-serialized form?

[Pharo-project] Job ProgressBar logic is bogus
by StÃ©phane Ducasse Nov. 3, 2012

Nov. 3, 2012

Job ProgressBar logic is bogus here we have: progress ^ (currentValue - min) / (max - min) raises ZeroDivide. and progress is invoked by basicProgress: basicProgress: aNormalizedFloat "Set the progress: 0.0 - 1.0 without triggering an update" currentValue := (min + ((max - min) * aNormalizedFloat)) In my case I have currentValue, min and max = 1 does anybody know this code? and how we can fix it. How to reproduce the problem MCStReaderTest debug: #testCommentWithStyle Here we have fileInFrom: aStream | changes | changes := ChangeSet scanFile: aStream from: 0 to: aStream size. aStream close. ('Processing ', self packageName) displayProgressFrom: 1 ^^^^^ which set the min to 1. Setting it to 0 can solve the problem but the progress bar should be more robust to: changes size ^^^^^^^^^^ max to 1 during:[:bar| | chgRec | 1 to: changes size do:[:i| bar current: i. chgRec := changes at: i. self perform: (chgRec type copyWith: $:) asSymbol with: chgRec. ]. ].

[Pharo-project] Aida with Realtime (WebSockets) support released
by Janko MivÅ¡ek Nov. 2, 2012

Nov. 2, 2012

Dear Smalltalkers, I think it can be safely claimed that Aida/Web is a first Smalltalk web framework, even more, one of the first frameworks at all to integrate HTML5 WebSockets for so called realtime web apps. Realtime in sense that values on the page are updated immediately when value changes on the server, without needing to manually reload a page. You can see that in action from WebSocket-capable browsers (latest Firefox and Chrome) if you open in two browsers the online Aida realtime counter demo, click buttons on one and observe changes instantly in both browsers: http://demo.aidaweb.si/demos?view=realtime And how easy is using real-time in your code? See the simplified code of above demo: WebDemoApp>>viewRealtime | e counterElement | self enableRealtime. counterElement := e add: self counterElement. (e addButtonText: ' Decrement ') noSubmit; onClickDo: [self observee decCounter]. (e addButtonText: ' Increment ') noSubmit; onClickDo: [self observee incCounter]. self observee onChangeDo: [counterElement update] on: counterElement app: self. self add: e. WebDemoApp>>counterElement | e | e := WebElement newSpan. e style: 'font-size: 40px'. e addText: self observee counter printString. ^e To describe this code a bit: you first enable realtime for this view of demo App. Element on the webpage to update in realtime must be created in a separate method (#counterElement). After buttons for increment and decrement we come to the main part - registering the block to execute on every change of domain object. Calling simply #update to the counter element is enough to be updated on all browsers which currently observe that counter demo. How this works? Behind the scenes a so called realtime channel is open between browser and Aida server. This WebSocket based channel is bidirectional and full-duplex, meaning that Aida can send back to the browser a message at any time. In above case a command to update the counter element is sent back to all browsers immediately after counter is changed. New Aida 6.5 Interim release is released for Squeak, Pharo and VisualWorks and available from usual places. See http://www.aidaweb.si for more. Everyone is welcome to try it and come with suggestions how to use this new feature, how to improve it, ....
