[Pharo-project] My idea of Metacello configurations for Pharo
by Mariano Martinez Peck Dec. 30, 2009

Dec. 30, 2009

Hi folks. I just wanted to write down my ideas of the Metacello configurations for our Pharo Images. The idea is to use Metacello to manage the dependencies and version of the packages, have a history of the releases and be more modular. You will be able to take a core image and easily load what you want. We will have a ConfigurationOfPharo and that's what you will probably use. However, this conf depends and delegates to another configurations (the conf of each package). So, the first step is to make each little conf to work, and then, we focus in the pharo one. So....lists of points: 1) I have been writing several configurations so far. One configuration per external project that is loaded in Pharo Dev images. Examples: Shout, OCompletion, RefactoringBrowser, OmniBroswer, O2, etc.. The idea is to implement and be sure each of this conf is working before doing the ConfigurationOfPharo. 2) All configurations will be published here: http://www.squeaksource.com/MetacelloRepository This repository is like the ibiblio for maven, or the Universe for the apt-get, or similar. In a near future we will have tools that work with this (Esteban Lorenzano is working in Loader for example). 3) Each configuration must be PERFECTLY loaded in a Pharo Core image without doing or installing nothing. To do this, I have to declare properly the dependencies. This mean, that you will be able to take a core image load the ConfigurationOfShout for exameple, or OCompletion and you will be able to load it. Metacello will take care of all the dependencies. You will also be able to install part of the project and not all (for example, only core or core + tests, or whatever). 4) I started with the Dev packages. We will do this test first to see if Metacello really help us in our project. If this goes well, then, in a second step, we will take care about the Web images. 5) I started with the 1.0 Dev packages. 1.1 is unestable and several external packages even don't load in it. So, will do 1.1 in a second step. 6) As there were no versions of Metacello in all the external projects, I started with 1.0 in ALL. Shout 1.0, OCompletion 1.0, RB 1.0, etc. This has nothing to do with Pharo 1.0. They are just the version number. And after this is released, we really need PLEASE, that the maintainers of those packages also creates the following versions for them. 7) I took as a base, the versions of the 10496 image. I have been using this image since in was release, 12 hours a day, and seems to be very stable to me. I mean, the version 1.0 of ConfigurationOfPharo will be like the 10496 image. When everything is done and working, create a new image will be very easy. 8) We need some features from Metacello which are in the todo list. So, we will have to wait a bit for them. OK, that's all. What do you think? Soon I will send an email for the configurations of all projects and will ask for help and feedback from their developers. Cheers, Mariano

Re: [Pharo-project] Issue with gofer/metacello

I've been able to address the problems with Metacello and pharo1.0-10502-rc1dev09.12.2. Version 1.0-beta.18 (just released see: http://groups.google.com/group/metacello/msg/a12918b4bd11c0ef for the announcement) has been tested with both: - pharo1.0-10493-rc1dev09.11.2 - pharo1.0-10502-rc1dev09.12.2 the class-side #ensureMetacello methods for configurations also need to be updated to work with pharo1.0-10502-rc1dev09.12.2. See: http://code.google.com/p/metacello/wiki/EnsureMetacello for a suggested implementation. I plan to update the #ensureMetacello methods for the configurations in MetacelloRepository tonight.

[Pharo-project] Help with a crash
by Mariano Martinez Peck Dec. 30, 2009

Dec. 30, 2009

Hi folks! I am having a crash in Mac OS using Squeak 4.2.2beta1U.app when trying to swap out unactive classes. In the image it appears a windows or something like a console with just a part of the stacktrace. I attach an screenshot. In PharoDebug.log I have nothing. I even tried to run the VM from command line, but nothing is shown in the console.. I opened a MacOS Console and the only thing I see is: "12/29/09 5:54:19 PM Spotlight[217] Invalid kMDItemPath for pharo1.0-10496-rc1dev09.11.5.dbx.changes " So, how can I get the full stacktrace of that ? Thanks Mariano

Yes. I definitely want to have a new release that includes all of Lukas' latest work, pulled from the wiresong repository. I'm just a bit bogged down in Real Life at the moment. :-) Colin

[Pharo-project] Issue with gofer/metacello
by Alexandre Bergel Dec. 29, 2009

Dec. 29, 2009

Hi! Last week, the following expression was used to load Mondrian. Gofer new squeaksource: 'Mondrian'; addPackage: 'ConfigurationOfMondrian'; load. (Smalltalk at: #ConfigurationOfMondrian) perform: #loadLastStable. With the last version of Pharo (10502), I get few deprecation warnings (package: should be used instead of addPackage: and version: instead of addVersion:). After proceeding these warnings, I have a rollback: MNU GoferPackageReference class>>name:repository: Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Yes, we definitely need a little more process around this. I'm thinking of having a separate inbox repository where contributions can be made. Once a contribution had been tested, it would be promoted to the main repository. Ultimately, I'd like to have a robot do at least part of that - run the tests and either report test failures or promote the changes - but for now we can do it manually. Thoughts? Colin

Dec. 29, 2009

>We have been discussing this and we want to be sure people understand that >1.1 is unstable and very yet in development. Yes, but I name them similar to the images they were built from (the ones Damien provides). You have to ask him to rename them first. At least I've updated the download page to: Windows Installer 1.0-10502-rc1dev09.12.2 (Pharo 1.0 RC1) Windows Installer 1.1-11112-alphadev09.12.2 (Pharo 1.1 unstable Alpha) Bye Torsten -- Jetzt kostenlos herunterladen: Internet Explorer 8 und Mozilla Firefox 3.5 - sicherer, schneller und einfacher! http://portal.gmx.net/de/go/atbrowser

If you're running a test suite to ensure that OB is working, it should include all the Refactory tests. BTW, no disrespect intended. I'm very glad to have refactoring integration in OB, tests or no tests! Colin
