OSProcess error with Linux 64-bit VM
by Luke Gorrie July 19, 2017

July 19, 2017

Hoi, Does OSProcess work for other people with a 64-bit Linux VM? I am seeing strange errors specifically when I build in 64-bit mode: Processes always immediately print an obscure error and exit with status 127. The error is printed by the child process. It seems to contain some control characters, or a funky text encoding, and a large number for its error code. [pid 19070] writev(2, [{"/bin/sh", 7}, {": ", 2}, {" \n\2303\374\177", 6}, {": ", 2}, {"", 0}, {"", 0}, {"\270\271\247\336;\177", 6}, {": ", 2}, {"Error 18446744073136382760", 26},\ {"\n", 1}], 10) = 52 More complete strace output in this gist: https://gist.github.com/ 81ca7b1c6b8cc412b66951bb6d57e1ea Reproduce with e.g. OSProcess command: 'pwd' (it doesn't seem to matter what command is chosen.) Anybody else see this / not see this? Any ideas? Could be that some of the magic in the UnixOSProcessPlugin fork method is not working on 64-bit or with my toolchain...?

Need help for SmartTest/CORA
by Benoit Verhaeghe July 19, 2017

July 19, 2017

Hi everyone, I'm working on SmartTest/CORA. It's a plugin that help us with test. It shows us only the test we should run to well tests ours applications. And it will run automatically the tests (or not if you disable this option). It will be great if you can help me by installing it. You only have to execute this command : Metacello new githubUser: 'badetitou' project: 'TestsUsageAnalyser-CORAExtends' commitish: 'master' path: '.' ; baseline: 'TestsUsageAnalyserCORAExtends' ; load . You can also use the plugin with jenkins. Everything are explained here : http://badetitou.github.io/research/smalltalk/2017/07/05/CORA/ Tell me if you are in trouble during the installation Thanks for your help Benoit

Automatic Refactoring Disranging Seaside Rest Methods
by lionelakue July 18, 2017

July 18, 2017

Hello everyone, When you copy an image or sometimes when you make a Metacello commit, your methods are automatically refactored. This uncleanse the code (replacing context meaningfull variable names with gereric identifiers) and prevents seaside request parameters . Which are mapped to method parameters by uri strings: ToDoHandler>>searchFor: aString <get> <path: '/search?query={aString}'> ^ String streamContents: [ :stream | ToDoList default items do: [ :each | (each title includesSubString: aString) ifTrue: [ stream nextPutAll: each title; crlf ] ] ] will become: ToDoHandler>>searchFor: arg1 <get> <path: '/search?query={aString}'> ^ String streamContents: [ :arg2| ToDoList default items do: [ :arg3| (each title includesSubString: aString) ifTrue: [ arg2 nextPutAll: arg3 title; crlf ] ] ] So will end having a Parameter not found exception because arg1 and aString mismatche. Is there a way to disable automatic refactoring?

by Mariano Martinez Peck July 18, 2017

July 18, 2017

Hi all, A while back our team presented Quuve [1], a customizable investment management ecosystem for professional investors. We also discussed the technologies employed to build it [2] (it is developed on Pharo and deployed on GemStone). We are reaching out again because we recently revamped our website [3] and created a number of promotional videos that demonstrate Quuve's power [4]. We would appreciate your help in marketing our wares! Quuve is the world's first fully integrated and customizable research and portfolio management platform. The system offers powerful features never before seen by the investment community and it empowers users to tailor tools in ways that accommodate their idiosyncratic investment style. In the coming years, customization, data-inheritance, shared databases, machine-learning, and robo-trading will become standard among investors of all sizes, and we expect Quuve will blaze the trail. If you have any questions about Quuve please let us know.

Recursively downloading Pharo packages / Building images with Nix
by Luke Gorrie July 18, 2017

July 18, 2017

Howdy! I want to build Pharo images using Nix <https://nixos.org/nix/>. On the one hand this should look basically like the Jenkins scripts, but on the other hand the build must run inside a sandbox that is isolated from the network. So I need to download all of the code that I need ahead of time because I am not able to contact Github, SmalltalkHub, etc, once the build is running. I am not sure how to approach this problem yet but I have a preliminary question. Is there an easy way that I could "recursively" download all the Smalltalk code (etc) required for an application onto the local filesystem, and then load this into a Pharo image that does not have network access? Concrete example - How could I write a Pharo script that downloads all the software required to install Moose in a standard Pharo 6.0 image? Then how could I load that into an image off the local filesystem? I feel like there should be a solution here, since Monticello seems to be able to cache packages locally on the filesystem, but I don't how enough experience to quite know how to approach it. If this is possible then the "utopian" vision could be to recursively download every Pharo package that exists, in every relevant version, and make them available in the Nix universe. This is what Nix does with Python, R, Emacs, etc packages. Or if this turns out to be difficult for some reason then I could perhaps build the Pharo image externally - e.g. on the Inria Jenkins - and then import that into Nix as an opaque binary. This is probably the simplest solution but it is not very appealing from my Nix-centric viewpoint because I won't have visibility into what has changed between one image build and the next. Feedback would be much appreciated! -Luke P.S.

Zinc redirect bug?
by Aliaksei Syrel July 15, 2017

July 15, 2017

Hello, I am trying to download a file from *bintray* with the help of ZnClient. I'm doing the following: ZnClient new systemPolicy; url: ' https://dl.bintray.com/syrel/Moz2D/osx/development/i386/libMoz2D.dylib'; get; yourself which results in Error 403. At the same time wget works as expected: wget https://dl.bintray.com/syrel/Moz2D/osx/development/i386/libMoz2D.dylib Trying to open this url in a browser works too. I tried to find out what may cause the error and it looks like it is something related to redirects because request and response headers look good... Thanks, Alex

macOS Sierra support
by Sven Van Caekenberghe July 15, 2017

July 15, 2017

Hi, Can someone who really knows/understand please describe where to find the necessary Pharo VM's to run on the newly released macOS Sierra (10.12) ? In particular it seems old VM's just stop working and recent VM's that do work either have issues or cannot run older (3.0, 4.0) images. Thanks, Sven PS: I have not yet upgraded, but one of my colleagues did and he got stuck: even after we found a VM that worked, it could only run 5.0 images, not his production 4.0 images. Needless to say, this is not good. PS2: Another really annoying problem is the following: he saved all his (really important) scripts using Script Manager as a FUEL. Moving between 4.0 and 5.0 FUEL stops working (version incompatibility) - this is really not cool, why would a newer FUEL not be able to read older FUEL. He ended up copying string data by opening the binary FUEL file in a text editor.
