Generally speaking, you should consider the image and changes file a pair and always send them together zipped. You might also sign up for a free Dropbox account at http://db.tt/slWGE17, it makes sharing large files trivial and free with direct links to them instead of forcing me to watch ads while waiting for a countdown. Here's a link to that image with the test running still up and all tests passing... http://dl.dropbox.com/u/7097835/SandstoneDBTestFails.image I didn't do anything at all, I simply ran the tests and they all passed. You've got something weird going on with your system. I'm also using cog, here's my version info... cog -version 3.9-7 #1 Fri Apr 1 12:48:48 PDT 2011 gcc 4.1.2 Croquet Closure Cog VM [CoInterpreter VMMaker-oscog.54] Linux mcqfes 2.6.18-128.el5 #1 SMP Wed Jan 21 10:44:23 EST 2009 i686 i686 i386 GNU/Linux plugin path: /usr/local/lib/squeak/3.9-7/ [default: /usr/local/lib/squeak/3.9-7/] So I'd suggest downloading a fresh one click image from the Pharo site, loading SandstoneDb, and running the tests again. If that fails, perhaps there are some permissions issues with the folders, try renaming the image and restarting it so a fresh set of folders are created and see if that helps. If you find more info or the issue I'm definitely interested in what caused it since I can't recreate the issue even in your image. -- Ramon Leon http://onsmalltalk.com

Moose solves a real and important problem that developers (both Smalltalkers and non-Smalltalkers) have: how to improve the productivity of the effort spent on assessment.

Call for ideas for DBXTalk UI

by Mariano Martinez Peck

Hi guys. Thanks to the ESUG SummerTalk, DBXTalk team has started to work with the new products of the DBXTalk suite. However, for one of the tools in special we would like to hear your opinion. Just a little introduction to the two other tools: 1) A new Glorp port from VW to Pharo. In addition, we provide the DBX driver for Glorp, by the name of GlorpDBX. Guillermo Polito is mostly working on this. 2) A new tool that uses Magritte and the database metadata to automatically generate the mappings between objects and tables. The idea is to do it two-way: a) read the metadata from an existing database -> create magritte descriptions -> generate Glorp mappings -> query with Glorp b) write magritte descriptions for the mappings -> generate database schema -> generate Glorp mappings -> query with Glorp or something like that....it is not completely decided but that's the idea. This way we can autogenerate the Glorp mappings and then use Glorp normally. Santiago Bragagnolo is working mostly on this. The third product, and here the question, is going to be a UI for the DBXTalk suite. This UI would do the core functionalities of tools like SQLDeveloper, MySQL Explorer, pgAdmin, etc. This is basically: - visualize and get information of: tables, views, schemas, relations, indexes, etc. - be able to modify the previous items and impact them in the database - write queries and get results So...why this tool if we can also use external tools like SQLDeveloper, MySQL Explorer, pgAdmin, etc ? a couple of reasons: 1) having the tool inside the image is easier (just the same way you sometimes install an Eclipse plugin instead of using such programs) 2) the same tool works for all databases 3) we can customize it with particular things of DBX Gisela Decuzzi is working mostly on this. Now....what use cases do you think are useful for such UI ? what kind of things would you like ? what things we can do that are related to Glorp and to the magritte tool? what things can we do to have even more advantages than just using external programs ? I have the following things in mind: - Special console for DBX/Glorp logs. - Be able to edit Magritte description for mappings. - Sync the tables and mapping while edditing. - A new inspector for inspecting restultsets, where you see one rows and columns. Let us know. Once again, thanks ESUG for the sponsorship to the team. Mariano http://marianopeck.wordpress.com

Relative position of submorph

by Ulrich Vollert

Hi, I am doing my first steps with Pharo, and I am deeply impressed and amazed about this wonderful development world of Smalltalk. Thanks to all developers who made Pharo available! As my first project, I am trying to develop an animation and want to animate a subclass of ImageMorph named PlaneMorph in a StandardWindow. I defined a method PlaneMorph>>step which calculates new positions like: step .... self position: newPosition When adding my PlaneMorph to a StandardWindow like window addMorph: PlaneMorph new the coordinates are not relative (inside) of the window but relative to the main window of Pharo. My solution to position PlaneMorph relative to the position of the StandardWindow: I tell the PlaneMorph to which surrounding window it belongs (PlaneMorph new window: window), store the window in an instance variable of PlaneMorph and positon it in PlaneMorph>>step relative to the window as self position: newPosition + window position Is this solution good design? I wonder whether it is a good idea that the PlaneMorph knows about the window. Regards, Ulrich
