github-cache organisation
by Ben Coman July 23, 2016

July 23, 2016

Just a general observation and first impression of installing a github hosted project. After installing OSSubprocess from the Catalog Browser on Pharo 50760, which uses repository... github://marianopeck/OSSubProcess:v0.2.4/repository ...I see file "github--marianopeckOSSubprocessv0241266307023333901887488330764830.zip" sitting next to my .image file. That would seem to dirty up that area when I start to use git more often. I'd expect that file to be placed in one of the cache folders. cheers -ben

[ANN] JSONWebToken
by Norbert Hartl July 22, 2016

July 22, 2016

Hi, thanks to the inquiry of Sven I published an implementation of JSONWebToken to smalltalkhub. It is available at http://smalltalkhub.com/#!/~NorbertHartl/JSONWebToken <http://smalltalkhub.com/#!/~NorbertHartl/JSONWebToken> For those who don't know JSONWebToken or short JWT pronounced "jot" is a token format suitable for authentication and authorization. The token consist of a header, a payload and a signature. The header defines crypto algorithms, compression and other things needed to read a token on reception. The payload is called a claim set which is basically a dictionary with well-known and custom keys. If we think about OAuth or OpenId the values contained map directly to JWT claims. For OpenID connect which is an identification mechanism on top of OAuth the usage of JWT is one of the building blocks. What are the advantages in using JWT? - it defines a header for encoding the content so it is quite flexible in the ways compression and encryption of the key is done - defines a payload which maps arbitrary keys and there is a set of well-known keys that implementations of OAuth, OpenID can understand - defines a signature that makes it easy to trust the information contained or to give the token to someone who is not trusted - token format is a single line string so it can be used e.g. in HTTP authentication headers A problem JWT can solve: In our company we have a lot of little REST servers serving some duties. To minimize the chaos I want to have a central authentication and authorization point. If we assume having 20 images running and we look at typical way how authorization works: there is image A (Authentication), image S (Service) und client C. Client C wants to use the service S 1. client C authenticates and retrieves authorization information from A (or from S which redirects him to A) 2. client C hands out the authorization information to S 3. S needs to check at A if the information is valid (client C could have modified it or generated it) 4. S grants C access Taking the assumption of having 20 service images, every image would need to get back to A in order to check authorization information. The more services images you have the more load it will put on A. In a JWT use case scenario the same would look like 1. client C authenticates and receives a JWT containing authorization information. The token is signed by A 2. client C hands out JWT to service S 3. S checks the signature of A and knows that the authorization information contained is valid. 4. S grants C access FYI, Norbert

[Ann] Major Seamless update
by Denis Kudriashov July 21, 2016

July 21, 2016

I glad to finally release new version of Seamless (0.8.2). It could be loaded by: Gofer it smalltalkhubUser: 'Pharo' project: 'Seamless'; configuration; loadStable. It works in Pharo 5 and 6. It is complete redesign of original version with the goal to make it more flexible, reliable and simple. (original version was created by Nikolaos Papoulias) Seamless is foundation for RemoteDebuggingTools. It allows reuse existing debugger to work with remote process by transparent network communication. Particularly new version provides required flexibility to reduce number of requests between distributed objects. No debugger changes was needed to make it work relatively fast with remote model. For more details look at my blog <http://dionisiydk.blogspot.fr/2016/07/major-seamless-update.html> and read docs: Seamless <https://ci.inria.fr/pharo-contribution/view/Books/job/PharoBookWorkInProgre…> and Basys <https://ci.inria.fr/pharo-contribution/view/Books/job/PharoBookWorkInProgre…> As usual feedback is welcome. Best regards, Denis

Athens Font Rendering Bug
by J.F. Rick July 20, 2016

July 20, 2016

Perhaps other people have already reported this for Bloc but something is wrong with the font rendering of Athens. Here's the code and how it is rendered in Athens vs how it is rendered in BitBlt. It seems like Athens adds more space between letters than is supposed to be there. tMorph := TextMorph new. font1 := TextFontReference toFont: (LogicalFont familyName: 'Arial' fallbackFamilyNames: nil pointSize: 28 stretchValue: 5 weightValue: 400 slantValue: 0). font2 := (TextFontReference toFont: (StrikeFont familyName: 'Atlanta' size: 11)). t1 := 'this is font1' asText addAttribute: font1. t2 := ' and this is font2' asText addAttribute: font2. tMorph contents: (t1,t2). Cheers, Jeff

State of Pharo in comparison with the "Pharo vision" document
by Julien Delplanque July 20, 2016

July 20, 2016

Hello everyone, For a university project I need to write a little about Pharo. I found the "Pharo vision" document [1] and I am curious about the actual state of Pharo in comparison with it. I have seen some things on the mailing list but I would like some help to gather the state of each goal described in "Pharo vision" version 1.0. I made a list with the goals and wrote some of the (little) knowledge I have about some elements (I also joined it to this mail in case it is not readable): Goals -> State ------------------- 1. Creation of the Pharo Consortium -> Created 2. Small kernel & validated packages -> ? 3. A Robust and Extensible System Events -> ? 4. Rewrite of Filesystem/Streams -> ?/XStream? 5. Announcements and Ephemerons -> ? 6. UI Canvas for Zoomable Interfaces -> Bloc? 7. Bootstrap of the Core -> ? 8. Fully parametrized compiler tool chain -> ? 9. Packages as real objects -> ? 10. Package Meta-Data -> PackageManifest? 11. Less Model Clutter and Duplication -> ? 12. Building and Reusing UI Logic -> Spec? 13. New Network Layer -> ? 14. Serializers -> Fuel 15. SystemChangeNotifier replacement -> ? 16. Cleaning Morphic -> Still valid? (asking because of Bloc existance) 17. Everybody should be able to compile VMs -> ? 18. VMs identification and regression testing -> ? 19. One Unified FFI framework -> Created and still being enhanced 20. 64 Bits -> I saw the screenshot on Twitter but what is the state now? 21. New Object Formats -> ? If some of you know the state of one or many of these project and have the time to give me some information about it/them, I would be really grateful. Thanks in advance, Julien Links: [1]: https://gforge.inria.fr/frs/download.php/30434/PharoVision.pdf

Support for more arrays
by Thibault Raffaillac July 20, 2016

July 20, 2016

Hi, Here is a quick draft for more array sizes as discussed last week. http://smalltalkhub.com/#!/~ThibaultRaffaillac/Collections-Arrays It yields (* => new): SByteArray* and ByteArray ShortArray* and UShortArray* IntegerArray and UIntegerArray* LongArray* and ULongArray* SWordArray* and WordArray FloatArray and DoubleArray* I don't know if this is the right way to make a package (also considering the obvious name), anyway here are the unresolved issues: _ ByteArray and WordArray are unsigned, IntegerArray is signed! The package does not rename any though, I go for conservative :p _ Do we have primitives for 8/16/32/64 sreads/ureads/writes? Doing sign extension by hand is painful. _ Same for 32/64 bit IEEE float reads/writes? Current code implicitly transfers float values through integer registers which is SLOW (worse on ARM). _ A big part of the system is hardcoded with assumption (isBytes or isWords), therefore the inspector does not seem to display values&metadata properly. We should probably fix all occurrences of isBytes. Is there a bug filed already? Cheers, Thibault
