[Pharo-project] [BUG][FIX] CompiledMethodTrailer
by Igor Stasenko May 12, 2011

May 12, 2011

Okay, seems like i found the bug. (CompiledMethodTrailer new sourcePointer: 0) testEncoding fails. And it happens only when you pass 0 as source pointer!! Such an obscure case! @squeakers, for the context, check the discussion "Problem with CompiledMethodTrailer" in pharo-dev list.

Because this means that everything is GPL, and that people therefore will have problems using it to make money in many cases. (and no, the GPL does not help to get contributions back: I *do not want* contributions of code where the author is forced to release code...)

[Pharo-project] legal counsel for pharo?
by merlyn＠stonehenge.com May 12, 2011

May 12, 2011

A question recently came up on the squeak-dev mailing list about the legality of including GPL code in Squeak core, as to where the line might be. This is especially interesting because of the OpenQwaq release recently. I was able to answer the question for Squeak core definitively by saying "if you have questions, Squeak is part of the SFC, so we have legal representation through the SFLC". This permits potential contributors to get free legal advice about whether their code would be permitted into Squeak core without violating the Apache/MIT license. Which got me wondering, for Pharo, what's the equivalent? Have you guys retained a lawyer or other arrangements for which you can sort out license issues? Who is the "SFLC" equivalent for Pharo? -- Randal L.

Hi guys With cyrille we experience sometimes CompiledMethod with nil category and this can break hard some problem. We were thinking but not sure that it would be good to make sure that nil is not returned but 'as yet unclassified' What do you think? Do you have any idea of potential problem? Stef

[Pharo-project] Call for ideas for DBXTalk UI
by Mariano Martinez Peck May 12, 2011

May 12, 2011

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
