[Pharo-project] Don't ever ever halt in #startUp:
by Sebastian Sastre Nov. 10, 2012

Nov. 10, 2012

â¦I mean ever. Because you'll screw your image. Mostly when you also are on OS X but, for some crazy reason of the Universe, your TimeMachine was not operating normally on your laptop while coding. Aaaaand you weren't committing in the monticello repo because it was work in progress and you were expecting to reach some goal. Ever. Soâ¦ I'm in that situation with an image now :( I've the false good idea of putting a halt in an SomeApp class>>startUp: method and now, when I open the image, it tries to, stays for about 2 seconds and crashes. Any of you guys have a workaround/hack to rescue it? sebastian o/ PS: I've tried with startup.st with the code that removes that method but no luck.

Re: [Pharo-project] NB Capabilities
by Fernando Olivero Nov. 9, 2012

Nov. 9, 2012

Hi, i wanted to give my opinion on this, since i've encountered some of the problems you mention. Sometimes to benefit from the simplicity of Smalltalk while coexisting with other tools, we must cope with low level technology "glue code". NB made it easy to do so, compared to Alien,FFI, writing plugins in C. When i first started with Squeak and the Pharo1.0, it was a real pain interfacing with external libraries, THANKS Igor! Still someones needs to do it, hence why a lot of people of this community spent loads of time coding this "extra work" to be able to do their "real work". I wouldn't say that you need to be extremely bright to built a wrapper library using NB, once you know what api you want to call, and the type of arguments. There's plenty of examples out there, and Igor always responds with tough questions! Give a try! maybe its easier than you think.

[Pharo-project] Recovering Changes from a broken image
by Sven Van Caekenberghe Nov. 9, 2012

Nov. 9, 2012

Hi, One of the cool things of Smalltalk's images/changes file is that you can do a World Menu > Tools > Recover lost changesâ¦ to get back most [1] of your code in case your image/OS/machine suddenly crashed or you forgot to save your image or commit your Monticello packages. But we all have encountered the situation where the image is broken, saved in such a state that it no longer starts up properly. In that case your code might seem lost forever. No, it is not ! Two days ago I had this problem myself and I remembered something Marcus said some time ago: you can access the changes file of one (in casu your broken image) from another (working) image to select/recover the changes you want. It worked perfectly. The easiest procedure it to copy the .changes file from the broken image and rename its extension to .cs and then open it from a World Menu > Tools > File Browser and open a Changes browser on it. I found this very useful. This is a really important technique to be aware of. Sven [1] Sadly, not everything is logged in the changes file: creation of new classes, method deletions are not recorded. -- Sven Van Caekenberghe http://stfx.eu Smalltalk is the Red Pill

[Pharo-project] [Jenkins] about Pharo ci infrastructure...
by Marcus Denker Nov. 9, 2012

Nov. 9, 2012

Hello, We are experiencing some stability issues with https://ci.lille.inria.fr/pharo/ But the good news is: people here have been busy, and there will be a completely new ci infrastructure soon. https://ci.inria.fr This is right now in Beta, so please do not yet request accounts without checking with us first (and in general, it makes only sense to have an account if you need to do something like changing the configuration, not for normal use like downloads or checking the status of a build). This setup is for inria-wide deployment, and inria is a bit larger then RMoD... there are over 170 teams, >4500 employees... so this installation needs to be tested well before it can be rolled out. The good news is that RMoD (and thus Pharo) is part of the beta test! TimeLine ------------- -> Beta test started 31/10 -> We will recreate the whole setup of the old jenkins there for testing (possibly simplified using the new command line options) -> The installation will go in production in January What will it give us? ----------------------------- -> We can create whole Jenkis setups by pressing a button. (e.g. we will create a private RMoD ci server for internal things, we could think about splitting the VM builds into it's own Jenkins, or a jenkins for every version of Pharo...) -> Slaves can be created easily (uses CloudStack behind) -> external guest users can connect to the slaves via SSH (or remote Desktop for Win) -> much better infrastructure and support -> *Much* more resources. Disk size for Slaves, space for keeping artefacts So, the ci infrastructure of Pharo will see a very boost soon. Marcus -- Marcus Denker -- http://marcusdenker.de

[Pharo-project] Pharo Kernel Tests failures
by Pavel Krivanek Nov. 9, 2012

Nov. 9, 2012

Hi, I created a summary of tests that fail on Pharo Kernel. Currently 44 tests are failing as result of about 16 issues. https://docs.google.com/spreadsheet/ccc?key=0AjSsmZhqtUTedHBid1R4U0hFOVBWME… Keep in mind that Pharo Kernel has not complete tests coverage because some tests packages need reorganization. On the other hand the amount of loaded tests is not small. It has 7250 tests while full Pharo has 9659 tests. Help in this area is welcome ;-) We (at least I) want to have green tests for the final 2.0 release. Cheers, -- Pavel

Re: [Pharo-project] [ANN] Pharo Online Help 1.0
by Stephan Eggermont Nov. 9, 2012

Nov. 9, 2012

Hi Torsten, You might be interested in the TutorialBrowser in http://ss3.gemstone.com/ss/SpaTutorial It uses Glamour to build both tutorial texts and exercises where the exercise can be done directly in the browser. To see all, you need to load the data from the attached zip. Set the loading director in the Configuration (bad name, I know) The latest version is the XpDays2012 Next step would be to integrate the markdown parser and create better looking texts.

[Pharo-project] Fixing the StackInterpreterSimulator for Pharo 1.4
by Stefan Marr Nov. 9, 2012

Nov. 9, 2012

Hi: The attached change set fixes bit rot in the StackInterpreterSimulator and related classes. Here a brief summary: - VMClass>>#doOrDefer: now uses ProcessBrowser>>#isUIProcess: instead of Project - it replaces the use of #asDisplayText with StringMorph>>#contents:. - use of ThreadStream>>#on: is replaced with ThreadSafeTranscript>>#new - Utilities is replaced by UIManager>>#default - and #primitiveGetAttribute now uses the non-depricated `Smalltalk vm getSystemAttribute: attr` For the last change, I wonder whether that's going to work, because that code is going to be translated to C, right? Is anyone interest in these changes? Should I also fix the other simulators? With them, I can load a Pharo 1.2.1 image in the simulator, I wasn't patient enough to wait for a 1.4 image to complete loading. | sim | InterpreterStackPage initialize. sim := StackInterpreterSimulator new. sim openOn: '/.../Downloads/Pharo-1.2.1-11.04.03/Pharo-1.2.1.image'. sim openAsMorph. [ sim run ] fork.
