Re: [Pharo-project] Weird problem...having several "implementors" for the same method and class

by Mariano Martinez Peck

Benjamin: do, I don't do any copy explicitly. Eliot: yes, I thought it should be somethig related to that. Even more, I already tried Smalltalk fixObsoleteReferences, but still the same problem. Now, I have inspected those 4 copies of the CompiledMethodClass , and see the pointers to them, and all of them are pointed from an array. Here I attach an screenshot of the array and my proxies. Now the problem is that I don't know which is that array, nor how to fix it. Do you imagine which array can be? If I try to do a chase pointers of that array, the image hungs... I tried also evaluating ScriptLoader new cleanUpForRelease that does a lot cleanings...but they remain there. If I load all my code in a fresh image, I dont have it 4 times...only one. So I guess that something happened in my image. The array you see in the picture has: 'an Array(BalloonState UndefinedObject Boolean FillStyle Authorizer ConnectionQueue Password ChangeRecord MidiPrimTester BitBlt MailAddressParser PopUpMenu Random

Re: [Pharo-project] Fwd: [Hudson] 'Pharo' activated

by Adrian Lienhard

What's the status of Hudson? I can help configuring and maintaining it if needed. I was looking at the tests in in the latest PharoCore and what would be very helpful is to know since which update a test is failing to be able to relate the failure to a specific change. It would also allow us to fix tests (or the change that broke them) immediately after an update. This is much more effective than fixing tests half a year later. In the latest core we have: 7908 run, 7826 passes, 50 expected failures, 20 failures, 12 errors, 0 unexpected passes Cheers, Adrian On Sep 15, 2010, at 08:58 , Marcus Denker wrote: > > On Sep 15, 2010, at 12:09 AM, Schwab,Wilhelm K wrote: > >> Which targets do you plan to offer? >> > core 1.1.X > full 1.1.X > one-click 1.1 > core 1.2 > > later: > ful 1.2 > one-click 1.2 > > even later: > vm for mac, win, linux auto-build > > Projects: > - Opal > - Ocean > ..... more as needed > > > -- > Marcus Denker -- http://www.marcusdenker.de > INRIA Lille -- Nord Europe.

Re: [Pharo-project] Pharo integration in enterprise feedback

by Tudor Girba

Hi, I recently introduced Pharo in a small-medium software company (parametrix.ch). They use it for Moose (moosetechnology.org) to analyze their systems written in various languages and to introduce an assessment approach in their day to day development process (humane-assessment.com) A number of them are now learning to program in Pharo and Moose.

Hello, I don't have any such stories. I am using Pharo personally and for business, but I own the business I use it for. :) I think an effective way to evangelize Pharo/Squeak/Smalltalk is to when anybody has the liberty to do so, use it in the small areas where the business has a need and no dependencies or any particular bureaucratic requirements. Encourage coworkers to try it for personal projects, invite them to local user groups. Even if it is simply to explore something different and unknown. Find out some of their interests and where possible and reasonable demonstrate a Pharo solution for their interests. I think the more people we can get to choose Pharo/Squeak/Smalltalk for personal interests, the more people will begin to use it for the jobs at work that they have the liberty to choose. Over time this could lead to understanding of the benefits that Pharo/Squeak/Smalltalk can bring to the enterprise environment or to the developers life in general. If they use it at home, they may also help to improve our enterprise story so that they can make a living using their tool of choice. In the meantime we can improve our enterprise story. And I think we are working on that. Working both ends toward the middle seems to be the way to proceed to me. Just a few thoughts. Jimmie
