[Pharo-project] Surprising binary messages!

5 is the surprising answer of the expression: 6 + 4 / 2 It should be 8 But, I got 5 in both 1.1 and 1.2. Noury

Ah, my bad, I misspelled the category on XTReadStream and so it was omitted. I didn't find a way to browse a "package" in Pharo 1.2 so I'm struggling a bit to keep the categories in line. Thanks for the note, a new version of Xtras is on squeaksource.

>the current behavior of ConfigurationOfPharo loads Metacello >completly, included packages like Metacello-Help and Metacello-ProfStef OK, then its fine >someone can update that to 1.0-beta.28 and you will see the new versions. When I switch to Metacello "1.0-beta.28" in ConfigurationOfPharo then it fails while loading OB. A conflict since Metacello uses OB too, maybe in another version?

[Pharo-project] Xtreams-Xtras: hashing and HMAC
by mkobetic＠gmail.com Jan. 18, 2011

Jan. 18, 2011

I started playing with FFI and got the hashing streams working. They require OpenSSL's libcrypto, which should be available on any reasonably recent Unix and OSX. The VW version also has interface to native Windows bcrypt.dll (available on Vista and later) but I haven't done that part yet. Anyway the hashing streams seem to work and performance isn't bad either. Hashing 100MB of ones [ (([ 1 ] reading limiting: 100000000) hashing: 'md5') -= 0; close; digest ] timeToRun takes little over 5 seconds on not particularly fast machine. The above expression runs about 2.5 times faster on VW on the same machine, but that's probably due to the time spent in the block based terminal. Profile on VW says that only about 15% of the time is spent in the hashing layer. Hashing the 21M pharo image is pretty much instant: ((FileDirectory default / 'pharo.image') reading hashing: 'md5') -= 0; close; digest The code is in Xtreams-Xtras and Xtreams-XtrasTests (note that you'll have to load FFI!). I tested it on Pharo 1.2 beta with both cog vm and standard vm. There are few test failures with file terminals that don't seem to like to be closed twice. Should be an easy fix. Enjoy, Martin P.S.: If any resident FFI experts find the time and interest to look over my C bindings and find something wrong, please let me know. In particular I have't quite figured out how to work with struct fields that contain arrays (e.g. 'unsigned char [128]'). I figured out that I can declare the actual size of the field as a third parameter in the #fields declaration, but the accessors generated for the field are not right. I suspect they need to be some form of ExternalData but I don't quite grok how that should be created (see e.g. HMAC_CTX>>key). Also it seems that there isn't a type definition for 'int' so I'm replacing all references to that with 'long'. Is that how it's done?

Re: [Pharo-project] [squeak-dev] more Info in aboutSqueak

In the SystemReporter you can chose what system information should be gathered. So you could have a compact overview of the image and the VM or a full length/all details report. Add the repository SystemReporter to Monitcello. MCHttpRepository location: 'http://www.squeaksource.com/SystemReporter' user: '' password: '' Load the package SystemReporter and do SystemReporter open in a workspace. This very simple and needs to be polished further. License is MIT and everybody is invited to add code. It's easy to extend the reporter and it is explained in the class comment. This works with Squeak Trunk and Pharo 1.1.1 (needs to get rid of the deprecation warning) Alex

[Pharo-project] Metacello Help book in Pharo-Dev
by Torsten Bergmann Jan. 18, 2011

>The problem is that we have 25 pages of metacello explanation before that >blog (which will be added to the book chapter). Hi Stef, I do not mean to add the blog contents! His latest blog post shows a Pharo help book that is available as monticello documentation: See this screenshot: http://gemstonesoup.files.wordpress.com/2011/01/screenshot.png http://gemstonesoup.files.wordpress.com/2011/01/screenshot.png http://gemstonesoup.files.wordpress.com/2011/01/profstef-tutorial.png and I ask if it would make sense to add it to Pharo-dev by default or if one only gets it if he knows about Metacello and how to load this book. Since it includes the API-Doc I think this would mean to include Metacello too into Pharo-dev... Bye T. -- GMX DSL Doppel-Flat ab 19,99 Euro/mtl.!

Why? 6 + 4 is 10 and devided by 2 is 5. (there is no operator precedence) Marcus -- Marcus Denker -- http://www.marcusdenker.de INRIA Lille -- Nord Europe. Team RMoD.

[Pharo-project] Was not able to update with #12304
by Torsten Bergmann Jan. 18, 2011

Jan. 18, 2011

Looks like a Cog issue, I was able to reproduce it: When I download "PharoCore-1.2.zip" from https://pharo-ic.lille.inria.fr/hudson/job/Pharo%20Core%201.2/126/ (which is a Pharo 1.2 Core #12303 image) and I directly start the image with the latest Win32 Cog VM from Eliot then I'm not able to go through update #12304 via the update mechanism as I already wrote in [1]. I get this error: => ClassBuilder(Object)>>doesNotUnderstand: #reshapeClass:toSuper: When I use the standard VM I'm able to update correctly to the latest version pharo core 1.2 #12307 Maybe Eliot is able to reproduce and fix it. Until then I switch to standard VM.
